Squad

Shared context: read shared.md for project config & auth, pipeline levels, status transitions, API endpoints, error handling, and agent context flow.

Safety principles: read principles.md — mandatory, not optional.

Commands

/squad or /squad list — View Board

BOARD=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/board?project=$PROJECT&summary=true")

Output: markdown table with ID, Status, Priority, Title.

Epics: the board response carries an epics aggregate (each with children_progress and a derived epic_status). Group children under their epic from this aggregate + the embedded parent/children edges — never from tag parsing (see shared.md → Task Relationships & Epics). Show each epic's children_progress (e.g. 2/5 done).

/squad context — Session Handoff

Run first when starting a new session. Fetch board and output pipeline state: Implementing / Plan Review / Impl Review / Testing / Recently Done / Next Todo.

BOARD=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/board?project=$PROJECT&summary=true")

/squad add <title> — Add Task

1. Ask user for priority, level (L1/L2/L3), description, tags (use AskUserQuestion) 2. Build JSON safely with jq (see shared.md → JSON Safety), POST to API, capture the new task ID. tags MUST be a JSON array — the canonical stored format the board renders. Split the user's comma-separated input into an array, e.g. --arg tags "$TAGS" then tags: ($tags | split(",") | map(gsub("^ +| +$";""))) in the jq body (no tags → omit the field or pass [], never ""). 3. Images: if the user gave image file path(s) (e.g. /squad add "Login bug" --image ./bug.png, or "attach ./shot.png"), upload each to the new task via the attachment API (see shared.md → "Upload an image attachment"). Output the task ID + the returned attachment url(s). A pasted image with no path → ask the user to save it to a file first (the upload reads a local file).

/squad move <ID> <status> — Move Task

Always follow `shared.md` → Move Protocol in order.

Step 1 (check current status + level) → Step 2 (consult the matrix) → Step 3 (execute the move).

On 400: self-correct once via the response's .allowed[0]; notify the user after 2 failures.

/squad edit <ID> — Edit Task

Ask user which fields to modify, then PATCH via API. To attach an image to an existing task, upload a local image file via the attachment API (shared.md → "Upload an image attachment").

/squad remove <ID> — Delete Task

curl -sL "${AUTH_HEADER[@]}" -X DELETE "$BASE_URL/api/orgs/$SQUAD_ORG/task/$ID?project=$PROJECT"

/squad stats — Statistics

Column counts come from the board summary; per-actor token/event totals come from a single GET /api/activity/stats call (server-side GROUP BY actor — no per-task loop, no board fetch for tokens).

export BOARD=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/board?project=$PROJECT&summary=true")
export STATS=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/activity/stats?project=$PROJECT")
python3 << 'PY'
import json, os

board = json.loads(os.environ['BOARD'])
stats = json.loads(os.environ['STATS'])
columns = ['todo', 'plan', 'plan_review', 'impl', 'impl_review', 'test', 'done']

# Column counts (summary is keyed by status, each an array of cards)
counts = {col: len(board.get(col, [])) for col in columns}
counts['total'] = sum(counts.values())
print("## Column Counts\n")
print("| Status | Count |")
print("|--------|-------|")
for col in columns:
    print(f"| {col} | {counts[col]} |")
print(f"| **total** | **{counts['total']}** |")

# Per-actor token/event stats — straight from the aggregate endpoint
rows = stats.get('stats', [])
totals = stats.get('totals', {})
print("\n## Agent Token Usage\n")
if not rows or totals.get('tokens', 0) == 0 and totals.get('events', 0) == 0:
    print("No token data")
else:
    print("| Actor | Events | Tokens (est.) |")
    print("|-------|--------|---------------|")
    for r in sorted(rows, key=lambda r: r.get('actor', '')):
        print(f"| {r.get('actor', 'unknown')} | {r.get('events', 0)} | {r.get('tokens', 0):,} |")
    print(f"| **Total** | **{totals.get('events', 0)}** | **{totals.get('tokens', 0):,}** |")

/squad project — Current Project Context (AI Context Docking)

Fetch the current project's context from the projects table. Use this at the start of a session to load project purpose, stack, brief, relationships, and task counts in one call.

PROJECT_DATA=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT")

Output: formatted project context including:

• Purpose (WHY this project exists)
• Stack (technologies used)
• Brief (compressed current state + direction + recent decisions)
• Category and status
• Task counts by status
• Links to related projects

If the project is not registered, suggest running /squad-init to register it.

/squad project all — Full Project Map

Fetch all projects grouped by category. Useful for understanding the full project landscape.

ALL_PROJECTS=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/projects")

Output: projects grouped by category (e.g. personal, tools, skills) with names and purposes.

/squad project brief — View/Update Project Brief

The brief is a compressed context summary (200–500 chars) that agents consume at low token cost.

View current brief:

curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT" | jq -r '.brief // "No brief set"'

Set brief directly:

curl -sL "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT" \
  -H 'Content-Type: application/json' \
  -d '{"brief": "..."}'

AI-assisted update (`/squad project brief update`): 1. Fetch current project info + recent done tasks (GET /api/board?project=$PROJECT&summary=true) 2. Analyze: current state, recent completions, active direction 3. Draft a concise brief (200–500 chars) covering: what exists now, where we're heading, recent key decisions 4. Present to user for confirmation → PATCH to save

/squad project update <field> <value> — Edit Project Metadata

Update any project field via PATCH:

# Update purpose
curl -sL "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT" \
  -H 'Content-Type: application/json' \
  -d '{"purpose": "new purpose"}'

# Archive project
curl -sL "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT" \
  -H 'Content-Type: application/json' \
  -d '{"status": "archived"}'

Supported fields: name, purpose, stack, brief, status, category, repo_url.

/squad project link — Manage Project Relationships

# Add relationship
curl -sL "${AUTH_HEADER[@]}" -X POST "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT/links" \
  -H 'Content-Type: application/json' \
  -d '{"target_id": "other-project", "relation": "depends_on"}'

# Remove relationship
curl -sL "${AUTH_HEADER[@]}" -X DELETE "$BASE_URL/api/orgs/$SQUAD_ORG/projects/$PROJECT/links" \
  -H 'Content-Type: application/json' \
  -d '{"target_id": "other-project", "relation": "depends_on"}'

Relations: extends, serves, depends_on, shares_data.

Setup & Web Board

Run /squad-init first to register this project — it writes .squadrc (SQUAD_PROJECT=…, plus an optional SQUAD_ORG=<label> org selector) at the repo root, committed so your whole team's agents target the same board project. The token never goes in a project file — it's an org-scoped API key resolved as SQUAD_AUTH_TOKEN env > SQUAD_AUTH_TOKEN_<SQUAD_ORG> > bare SQUAD_AUTH_TOKEN= from ~/.squad/auth (see shared.md).

Open the deployed board at https://squad.steloit.com/?project=<PROJECT> (or via the configured SQUAD_BASE_URL). Features: 7-column pipeline, drag-and-drop (valid transitions only), card lifecycle modal, agent log viewer, 10s auto-refresh.

Squad Safety-First Principles

Speed is not the goal. Doing it right is the goal. These apply to every Squad skill and every pipeline agent — read them before planning or implementing a card.

---

Codebase-First Exploration (before planning)

• Don't assume — read the relevant files and existing patterns before you plan. A wrong

assumption early quietly contaminates everything downstream.

• Map the existing interfaces, file structure, and dependencies, then fix scope.
• Follow patterns already in the codebase rather than inventing new ones.
• "It's probably wired like this" is forbidden — plan only from facts confirmed in the code.

Card-Split Criteria

Split a card (or send it back to /squad-refine) if any hold:

• Estimated implementation time exceeds ~1 hour
• The change spans two or more layers (DB / service / UI / …)
• Rollback on failure would be complex — prefer small, reversible changes
• One or more requirements are still uncertain

Pre-Flight Check (before status → impl)

• Is the card's completion condition (done_when) clear and verifiable?
• Are in-scope and out-of-scope stated, so the work can't drift?
• If this card fails, are the other cards unaffected?

Done Means Verified (not "looks done")

• "Looks done" is not done. A card is complete only when its done_when checks have

actually run and passed — show the evidence (the command run and its output, test results, build exit).

• Run the gates before handing off: format, lint, typecheck, tests; fix what fails.
• Fix the root cause, not the symptom — never suppress an error to make a check pass.

Forbidden

• Starting implementation without refining first
• "Just ship it and clean up later" progress
• Expanding a card's scope mid-implementation
• Fixing friction with Squad itself inline, or leaving your task to chase it — if you notice friction with

Squad itself — the skills/board/orchestrator you work with, not the project you work on (an ambiguous skill instruction, an awkward board API, a clunky orchestrator step, a weak template, a bug), report it, don't fix it: file a friction report per shared.md → "Squad Friction Reports" and continue your actual task. The worked project's own bugs are NOT friction reports — those belong on that project's board.

• Planning from assumptions without reading the codebase
• Weakening a safeguard to pass review — deleting or skipping tests, suppressing

errors, or lowering a check instead of fixing the code

Squad DB Schema & Data Formats

Table: tasks

The task resource as returned by the board REST API (GET /api/orgs/:org/task/:id). This documents the JSON the API exposes — the board owns its own storage. Tasks are addressed by their display id <KEY>-<seq> (e.g. SQD-42) in every API path.

A projected read (?fields=a,b,c) returns only the requested fields (plus id, project, status); a full read (no ?fields=) additionally embeds activity, comments, and relationships.

Attachments are not part of the task JSON — they live behind their own endpoints

(POST /task/:id/attachment, DELETE /task/:id/attachment/:stored_name, download

GET /uploads/:stored_name). A task read does NOT embed an attachments array.

Agent Nicknames

Each agent has a fixed nickname used in all log records, field headers, and current_agent.

Signature Header Rule

Every agent MUST prepend a signature header to the content it writes:

> **Planner** `<MODEL_PLANNER>` · 2026-02-24T10:00:00Z

This makes every card field self-documenting — you can see at a glance who wrote what and when.

JSON Formats

review_comments / plan_review_comments

[
  {
    "reviewer": "Inspector",
    "model": "<MODEL_INSPECTOR>",
    "status": "changes_requested",
    "comment": "> **Inspector** `<MODEL_INSPECTOR>` · 2026-02-20T14:30:00Z\n\n## Review Findings\n\n1. Missing error handling",
    "timestamp": "2026-02-20T14:30:00.000Z"
  }
]

status must be "approved" or "changes_requested". reviewer must be the agent's nickname (e.g. "Inspector", "Critic").

test_results

[
  {
    "tester": "Ranger",
    "model": "<MODEL_RANGER>",
    "status": "pass",
    "lint": "0 errors, 0 warnings",
    "build": "Build successful",
    "tests": "42 passed, 0 failed",
    "comment": "> **Ranger** `<MODEL_RANGER>` · 2026-02-20T15:00:00Z\n\nAll checks passed.",
    "timestamp": "2026-02-20T15:00:00.000Z"
  }
]

status must be "pass" or "fail". tester must be the agent's nickname ("Ranger").

Table: task_activities

The immutable machine event stream for a task — one append-only event per agent step; events are never edited or deleted.

Event shape as returned by the activity API:

{"id": "<uuid>", "task_id": "SQD-42", "actor": "Planner", "model": "<MODEL_PLANNER>", "message": "Plan complete. 4 files to modify.", "tokens": 12000, "created_at": "2026-02-20T10:05:00.000Z"}

• id is an opaque string (used as the ?before=<id> pagination cursor); task_id is the display id <KEY>-<seq> (e.g. SQD-42), not a number. There is no project field on the event.
• actor is the squad actor (see actor vocabulary below); model is the resolved provider model from models.json (or system for Orchestrator/Heartbeat) — it may be null.
• tokens is optional/null — estimated total tokens (input + output) for the step; omit when unknown (missing counts as 0 in stats).
• created_at is server-set — clients do not send a timestamp.
• Clients send only {actor, model?, message, tokens?} on append. The board classifies each event internally (whether it was written by a human, an agent, or the system, and the kind of event); those classifications are NOT part of the append body or the returned shape — do not send or expect them.

Table: task_comments

The mutable human comment channel. Skills NEVER write this.

Comment shape as returned by the API: {"id": "<uuid>", "task_id": "SQD-42", "author": <string|null>, "content": "...", "created_at": "<iso>"} (task_id is the display id; there is no project field).

Activity & Comment Endpoints

Embedding rule: a single-task GET embeds the full activity + comments arrays only when there is no `?fields=` param; a projected read and the board summary/list do NOT carry them. Read activity via a full GET or GET /api/task/:id/activity — never ?fields=activity.

Actor vocabulary

(The Coach is not an activity actor — it writes to the run-audit store + files friction cards, never /task/:id/activity.)

Appending an event (orchestrator)

After each agent completes, the orchestrator appends ONE signed event — a single atomic POST, no read-modify-write:

python3 -c "
import subprocess, json
body = {'actor': 'NICKNAME', 'model': 'MODEL', 'message': 'MESSAGE'}
# Optional: include 'tokens' (estimated input+output), omit when unknown.
# body['tokens'] = TOKENS
subprocess.run(['curl','-sL',*auth_header,'-X','POST',f'{base_url}/api/orgs/{org}/task/{task_id}/activity?project={project}','-H','Content-Type: application/json','-d',json.dumps(body)], capture_output=True)
"

Replace NICKNAME with the agent's nickname (e.g. Planner, Builder), and MODEL with the resolved value from models.json.

Token Estimation Guide: the orchestrator estimates each agent's usage based on context size + output length. Example: context ~8k input + ~2k output → tokens: 10000. If unknown, omit the key (never send tokens: null) — missing tokens count as 0 in stats.

Table: projects

CREATE TABLE IF NOT EXISTS projects (
  id TEXT PRIMARY KEY,
  name TEXT NOT NULL,
  purpose TEXT,
  stack TEXT,
  brief TEXT,
  status TEXT DEFAULT 'active',
  category TEXT,
  repo_url TEXT,
  created_at TIMESTAMPTZ DEFAULT NOW(),
  updated_at TIMESTAMPTZ DEFAULT NOW()
);

Table: project_links

CREATE TABLE IF NOT EXISTS project_links (
  source_id TEXT REFERENCES projects(id) ON DELETE CASCADE,
  target_id TEXT REFERENCES projects(id) ON DELETE CASCADE,
  relation TEXT NOT NULL,
  PRIMARY KEY (source_id, target_id, relation)
);

Schema Migrations

New columns are added with ADD COLUMN IF NOT EXISTS in PostgreSQL — idempotent, no try/catch needed. Schema migrations run automatically on the board server at startup.

Squad Shared Context

Manages project tasks in PostgreSQL via the Squad board HTTP API. All projects share a single centralized DB on the deployed Squad board.

Project Config & Auth

Read the project name from .squadrc (SQUAD_PROJECT=, committed at the repo root, created by /squad-init). Auth is resolved tool-agnostically and org-scoped: the SQUAD_AUTH_TOKEN env var first, then the per-org SQUAD_AUTH_TOKEN_<SQUAD_ORG> line in the ~/.squad/auth credential file (mode 600), then the bare SQUAD_AUTH_TOKEN= default in that file. SQUAD_ORG is read from the env, else from .squadrc. The token is an org-scoped, scoped API key (carries its org + permission scopes server-side); it is never echoed, cat'd, or Read.

# 1. Project name: .squadrc → directory name
PROJECT=""
[ -f .squadrc ] && PROJECT=$(grep '^SQUAD_PROJECT=' .squadrc | cut -d= -f2-)
[ -z "$PROJECT" ] && PROJECT=$(basename "$(pwd)")

# 2. Auth token — env > per-org line > bare default (all from ~/.squad/auth)
SQUAD_ORG="${SQUAD_ORG:-}"
[ -z "$SQUAD_ORG" ] && [ -f .squadrc ] && SQUAD_ORG=$(grep '^SQUAD_ORG=' .squadrc | cut -d= -f2-)
if [ -z "$SQUAD_ORG" ]; then
  echo "ERROR: SQUAD_ORG is not set. Every board call is org-scoped (/api/orgs/<org>/...)." >&2
  echo "Set it from the mint dialog's \`SQUAD_ORG=<slug>\` line — add \`SQUAD_ORG=<slug>\` to .squadrc" >&2
  echo "(committed) or export SQUAD_ORG=<slug> for this shell. Resolution order: env > .squadrc." >&2
  exit 1
fi
AUTH_TOKEN="${SQUAD_AUTH_TOKEN:-}"; AUTH_SOURCE=$([ -n "$AUTH_TOKEN" ] && echo env || echo none)
if [ -z "$AUTH_TOKEN" ] && [ -f "$HOME/.squad/auth" ]; then
  if [ -n "$SQUAD_ORG" ]; then
    AUTH_TOKEN=$(grep "^SQUAD_AUTH_TOKEN_${SQUAD_ORG}=" "$HOME/.squad/auth" | cut -d= -f2-)
    [ -n "$AUTH_TOKEN" ] && AUTH_SOURCE="org:$SQUAD_ORG"
  fi
  if [ -z "$AUTH_TOKEN" ]; then
    AUTH_TOKEN=$(grep '^SQUAD_AUTH_TOKEN=' "$HOME/.squad/auth" | cut -d= -f2-)
    [ -n "$AUTH_TOKEN" ] && AUTH_SOURCE=default
  fi
fi
# The per-org grep is anchored `^SQUAD_AUTH_TOKEN_${SQUAD_ORG}=` so the bare
# `SQUAD_AUTH_TOKEN=` line can never match a per-org lookup, and vice-versa.
# Hyphenated labels match literally (it is a grep string, not a shell var name).

# 3. Board URL — env → ~/.squad/config → deployed default
BASE_URL="${SQUAD_BASE_URL:-}"
[ -z "$BASE_URL" ] && [ -f "$HOME/.squad/config" ] && BASE_URL=$(grep '^SQUAD_BASE_URL=' "$HOME/.squad/config" | cut -d= -f2-)
BASE_URL="${BASE_URL:-https://squad-api-285415501393.asia-south1.run.app}"
AUTH_HEADER=()
if [ -n "$AUTH_TOKEN" ]; then
  AUTH_HEADER=(-H "Authorization: Bearer $AUTH_TOKEN")
fi

If .squadrc is absent, PROJECT falls back to the directory name — prompt the user to run /squad-init to register it explicitly.

Resolution: token = SQUAD_AUTH_TOKEN env > SQUAD_AUTH_TOKEN_<SQUAD_ORG> (~/.squad/auth) > bare SQUAD_AUTH_TOKEN= (~/.squad/auth); SQUAD_ORG = env > .squadrc (required — every board call is org-scoped /api/orgs/<org>/...; unset is a fail-fast pre-flight error pointing to the mint dialog's SQUAD_ORG=<slug> line / .squadrc); URL = SQUAD_BASE_URL env > ~/.squad/config > deployed default; project = .squadrc (SQUAD_PROJECT=) > directory name.

Multi-org store format

~/.squad/auth (mode 600) holds flat, per-org lines plus an optional bare default — no INI/sections:

SQUAD_AUTH_TOKEN_acme=<acme org-scoped key>
SQUAD_AUTH_TOKEN_globex=<globex org-scoped key>
SQUAD_AUTH_TOKEN=<optional bare default key>

<label> is a local nickname (the org slug from the mint dialog) reused verbatim in .squadrc's SQUAD_ORG=<label>. Single-org users set nothing — just the bare SQUAD_AUTH_TOKEN= default, which is exactly today's behavior (back-compat). The store lines are emitted only by the mint UI (Settings → API Keys) — never by a skill, which never sees or writes the token.

Auth errors — 401 vs 403

The token resolves straight into the Authorization header; never echo/cat/Read it or ~/.squad/auth, and never use curl -v. Note: a missing SQUAD_ORG is a pre-flight failure — it stops before any request is even sent (no 401/403), with the actionable error above pointing to the mint dialog's SQUAD_ORG=<slug> line / .squadrc. Two distinct, scope-aware cases (plain text the agent relays — non-interactive):

• 401 (no / invalid / expired token). Board returned 401 — no valid token for $SQUAD_ORG/this board. The human mints or refreshes an org-scoped key in the board's web UI (Settings → API Keys) and runs the store command it prints — per-org line SQUAD_AUTH_TOKEN_<org>=… (multi-org) or the bare SQUAD_AUTH_TOKEN=… default (single-org), mode 600. The token is never pasted to the agent. (Don't print a URL — the skill only knows the API BASE_URL, and the mint page lives in the web UI; just point at Settings → API Keys.)
• 403 FORBIDDEN (valid token, missing scope). Board returned 403 FORBIDDEN — the API key is valid but lacks the required scope for this action. The human mints a key with the needed scopes in the web UI (Settings → API Keys). Do not retry until a wider-scoped key is stored.

SQUAD_BASE_URL is optional (defaults to the deployed board; self-host only, via env or ~/.squad/config).

Quick debug check before a failing request (value-free — never prints the token):

echo "SQUAD_PROJECT=$PROJECT"
echo "SQUAD_BASE_URL=$BASE_URL"
echo "SQUAD_ORG=${SQUAD_ORG:-unset (REQUIRED — fail-fast; add SQUAD_ORG=<slug> to .squadrc)}"
echo "SQUAD_AUTH_TOKEN=$([ -n "$AUTH_TOKEN" ] && echo configured || echo empty)"
echo "SQUAD_AUTH_SOURCE=$AUTH_SOURCE"   # env | org:<label> | default | none

Pipeline Levels

Level is set at task creation and stored in the level column.

7-Column AI Team Pipeline

Req → Plan → Review Plan → Impl → Review Impl → Test → Done

Model keys are resolved to real provider models through models.json.

Model Resolution

Skills that dispatch agents (squad-run, squad-refine, …) resolve models the same way — defined once here. Detect the provider, then read_model <key> / read_effort <key> look the key up in models.json.

# Provider: SQUAD_MODEL_PROVIDER env → Codex/Claude env signals → .claude/.codex dir → models.json default_provider
MODEL_PROVIDER=${SQUAD_MODEL_PROVIDER:-}
if [ -z "$MODEL_PROVIDER" ] && [ -n "${CODEX_THREAD_ID:-}${CODEX_CI:-}" ]; then MODEL_PROVIDER=codex; fi
if [ -z "$MODEL_PROVIDER" ] && [ -n "${CLAUDE_PROJECT_DIR:-}${CLAUDECODE:-}" ]; then MODEL_PROVIDER=claude; fi
if [ -z "$MODEL_PROVIDER" ] && [ -d .claude ]; then MODEL_PROVIDER=claude; fi
if [ -z "$MODEL_PROVIDER" ] && [ -d .codex ]; then MODEL_PROVIDER=codex; fi

read_model() {   # read_model <key> → real model name for the resolved provider
  local key="$1"
  python3 - "$MODEL_PROVIDER" "$key" <<'PY'
import json, pathlib, sys
d = json.loads(pathlib.Path("../squad/models.json").read_text())
provider = sys.argv[1] or d["default_provider"]
print(d["providers"][provider][sys.argv[2]])
PY
}

read_effort() {  # read_effort <key> → reasoning_effort for provider/key (may be empty)
  local key="$1"
  python3 - "$MODEL_PROVIDER" "$key" <<'PY'
import json, pathlib, sys
d = json.loads(pathlib.Path("../squad/models.json").read_text())
provider = sys.argv[1] or d["default_provider"]
print(d.get("reasoning_effort", {}).get(provider, {}).get(sys.argv[2], ""))
PY
}

Move Protocol (orchestrator-owned)

This protocol belongs to the orchestrator (squad-run). Only the orchestrator moves cards. Individual agents never run it — they record verdicts (via the record-only endpoints) and the orchestrator reads those verdicts and issues the move. Always follow this sequence before moving a card.

Step 1 — Check current state

TASK=$(curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/task/$ID?project=$PROJECT&fields=status,level")
STATUS=$(echo "$TASK" | jq -r '.status')
LEVEL=$(echo "$TASK" | jq -r '.level')

Step 2 — Determine next status via the Level × Status matrix

done has no forward transition — it is reached only by normal moves and left only by the explicit POST /api/task/:id/reopen action (done → todo). It is reopenable, not strictly terminal.

Step 3 — Execute the move

RESPONSE=$(curl -sL -w "\n%{http_code}" "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/task/$ID?project=$PROJECT" \
  -H 'Content-Type: application/json' \
  -d "{\"status\": \"$NEXT_STATUS\"}")
HTTP_CODE=$(echo "$RESPONSE" | tail -1)
BODY=$(echo "$RESPONSE" | head -1)

Self-correction on 400 (once)

if [ "$HTTP_CODE" = "400" ]; then
  # Read a valid destination from the response's allowed[] array and retry
  ALLOWED=$(echo "$BODY" | jq -r '.allowed[0]')
  if [ -n "$ALLOWED" ] && [ "$ALLOWED" != "null" ]; then
    curl -sL "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/task/$ID?project=$PROJECT" \
      -H 'Content-Type: application/json' \
      -d "{\"status\": \"$ALLOWED\"}"
  else
    # If allowed is also empty: keep status, record the failure via POST /activity, notify the user
    echo "ERROR: cannot move task $ID from $STATUS — API returned: $BODY"
  fi
fi

On 2 consecutive failures: keep status, record the failure via POST /api/task/:id/activity (actor=Orchestrator), notify the user.

API Access

All DB operations go through the deployed Squad board HTTP API ($BASE_URL).

The attachments field on a task read is a JSON array of {filename, stored_name, url, size, uploaded_at} — the url is a public R2 link, and the web board renders it for humans. Accepted: png, jpg/jpeg, gif, webp, svg. Deleting a task removes its R2 objects.

Viewing an attachment as an agent is host-dependent:

• Claude Code: download it (above), then Read the local file — it renders as vision. ✅
• Codex: a URL in the prompt is treated as text (not fetched); Codex sees images only when attached at launch via --image <path>. So download first then pass --image, or just cite the url.

Don't assume an agent auto-sees an attachment — surface the url/local path and use the host's image tool where available.

If AUTH_TOKEN is set, keep using the shared AUTH_HEADER array so every request can target the same protected board deployment without repeating conditional header logic.

Only a done task can be reopened; reopening clears its lifecycle timestamps and current_agent, preserves prior work (plan, comments, counts, results), and records the action as an activity event (server-side). Reopening any non-done task returns 409 {"error":"only a done task can be reopened","status":"<current>"} and changes nothing.

Optimistic Concurrency (version / ETag / If-Match)

Every task row carries an integer version that increases by 1 on every write. A single-task GET returns it both as the version field and as a strong ETag: "<version>" header.

To make a conditional (compare-and-set) write, echo that version back on the generic PATCH:

• If-Match: "<version>" header (preferred), or
• "expected_version": <version> in the JSON body (curl-friendly fallback; the header wins if both are present).

If the supplied version no longer matches the row, the PATCH is rejected with 412 {"error":"Precondition failed: version mismatch","currentVersion":<int>} and nothing is written — re-read the task and retry. Omit the precondition for an unconditional write (back-compatible default). A successful PATCH returns {"success":true,"version":<new version>} — except a bare same-status no-op PATCH (no field actually changes), which returns the full task row instead of {success, version}.

# Conditional update: only applies if the row is still at version 7
curl -sL "${AUTH_HEADER[@]}" -X PATCH "$BASE_URL/api/orgs/$SQUAD_ORG/task/$ID?project=$PROJECT" \
  -H 'Content-Type: application/json' \
  -H 'If-Match: "7"' \
  -d '{"status": "plan_review"}'
# → {"success":true,"version":8}   (or 412 {"error":"Precondition failed: version mismatch","currentVersion":<int>})

The pipeline orchestrator is the sole writer of status transitions, so by default it issues moves without a precondition — correctness rests on that single-ownership, not on the conditional write. The machinery above guards against other concurrent writers (a second orchestrator, a batch run, or a manual board edit).

Derived Verdict Fields (read-only)

A single-task GET exposes three read-only derived fields — the status of the latest verdict at each stage, or null if that stage has no verdict yet:

The orchestrator reads these to get each stage's verdict directly, instead of parsing the comment/result JSON arrays. They are computed fields, not columns — you cannot write them. A full read returns all three; a projected fields= read returns only those you name. (The board summary view computes only last_review_status and last_plan_review_status, not last_test_status — read the single task for the test verdict.)

Activity vs Comments

A task has two distinct append-only channels, backed by the task_activities and task_comments child tables (see schema.md):

• `activity` (machine event stream). Every event is produced by a squad actor as a side-effect of work — agent steps, the commit record, batch "Verified", kickstart "Impact", heartbeat warnings, reopen. Skills append events here; events are immutable (no edit/delete route). This replaces the old agent_log JSON column.
• `comments` (human channel). Free-form human comments only. Skills NEVER write the human channel (/comment). Machine records are events, not comments.

The differentiation rule: machine work → activity; humans → comments. A skill that wants to record anything it did writes an event, never a comment.

Append an event — POST /api/task/:id/activity?project=

The single atomic append path (no read-modify-write). Body {actor, model, message, tokens?}:

{"actor": "Builder", "model": "<MODEL_BUILDER>", "message": "Implementation complete.", "tokens": 25000}

• actor, model, message — required, must be non-empty strings.
• tokens — optional; if present must be a finite number (omit the key when unknown — never send tokens: null).
• No client timestamp — the server sets created_at.
• On success → {"success": true, "event": {id, project, task_id, actor, model, message, tokens, created_at}} and the task version is bumped.
• Invalid body → 400 and nothing is written.

Actor vocabulary (the actor field)

Pipeline agents do NOT self-append — the orchestrating skill (squad-run) appends one event per agent step; each agent writes only its own domain field (plan, implementation_notes, the verdict endpoints, …). See Agent Context Flow.

Read events — GET /api/task/:id/activity?project=

The purpose-built reader: chronological (ORDER BY id ASC), supports ?limit (≤500) and ?before=<id> for pagination. Returns {"activity": [<event>, …]}.

Full-read-only embedding

A single-task GET with no `?fields=` param embeds the full activity + comments arrays directly on the task. A projected read (?fields=...) does NOT embed them, and the board summary/list does NOT carry activity at all. So to read a task's activity, use a full task GET (embedded activity) or the dedicated GET /api/task/:id/activity — never ?fields=activity (not embedded) and never the board summary.

Per-actor stats — GET /api/activity/stats?project=[&task_id=]

Server-side per-actor aggregate (one GROUP BY actor) → {"success": true, "stats": [{"actor", "events", "tokens"}, …], "totals": {"events", "tokens"}}. The scalable source for cross-task token stats — one call, no per-task loop (the board summary no longer carries activity).

Human comments — POST /api/task/:id/comment · DELETE /api/task/:id/comment/:commentId

The human-only channel ({content}, optional author). Documented for completeness; skills must not write it.

Squad Friction Reports

Any squad skill or pipeline agent that hits friction with Squad itself (the skills/board/orchestrator you work with, not the project you work on) — an ambiguous skill instruction, an awkward board API, a clunky orchestrator step, a weak or missing template, an agent-ergonomics annoyance, or a bug — files a structured friction report so Squad improves from its own use. This is report, not fix: never leave your actual task to chase it, and never file the worked project's own bugs here (those go to that project's board). See principles.md → Forbidden.

A report is a low-priority card on project `squad`, tagged friction, triage. It lands as a todo card carrying both tags (not promoted into the active backlog); a human triages it later — promoting it into a real card (removing triage) or deleting it.

Report schema

The card description is this structured body (Markdown is fine; keep the field labels):

Anti-flood guardrails

• Evidence bar. No file:line or repro → do not file. Vague "this felt awkward" is not a report.
• Per-invocation cap N=3. A single skill run files at most 3 reports. One squad-run pipeline

pass counts as one invocation across all 6 agents (not 3 per agent) — the orchestrator owns the budget for a run; standalone runs (one refine, one explore) own their own.

• Dedup against the board. Before filing, read open friction cards and skip (or append your

evidence to a `friction`-tagged card) that already covers the same friction — match on area + the normalized title (lowercase, collapse whitespace, drop punctuation). Don't re-file a duplicate.

Dedup check (before filing)

# Open friction cards (not done), id+title from the summary.
# The summary is an object keyed by status (todo/plan/plan_review/impl/impl_review/test/done),
# each an array of cards; flatten the non-done buckets so `done` cards are excluded by construction.
curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/board?project=squad&summary=true" \
  | jq -r '[ .todo, .plan, .plan_review, .impl, .impl_review, .test ] | add // []
           | .[]
           | select((.tags // "") | test("friction"))
           | "\(.id)\t\(.title)"'
# If a returned title (normalized) matches your report's area+title, skip or append — do not re-file.

Filing a report (reuses the Create-task endpoint)

A report is created with the same `POST /api/task` documented above (API Access → API Endpoints), forced to project=squad, priority=low, with the two tags as a JSON array. Build the body with jq or Python (see JSON Safety) so newlines/quotes in evidence can't break the JSON:

SQUAD_BASE_URL_FOR_REPORTS="${SQUAD_BASE_URL:-https://squad-api-285415501393.asia-south1.run.app}"
BODY=$(jq -n \
  --arg area "board-api" \
  --arg severity "med" \
  --arg title "<one-line friction>" \
  --arg evidence "<what you did + concrete friction + file:line or repro>" \
  --arg suggestion "<optional fix/direction>" \
  --arg source_project "<project you were working on>" \
  --arg source_task "<task id on that project>" \
  '{title: $title, project: "squad", priority: "low", level: 1,
    tags: ["friction", "triage"],
    description: ("**area:** " + $area + "\n**severity:** " + $severity
      + "\n**evidence:** " + $evidence
      + "\n**suggestion:** " + $suggestion
      + "\n**source_project:** " + $source_project
      + "\n**source_task:** " + $source_task)}')
curl -sL "${AUTH_HEADER[@]}" -X POST "$SQUAD_BASE_URL_FOR_REPORTS/api/orgs/$SQUAD_ORG/task" \
  -H 'Content-Type: application/json' -d "$BODY"
# → {"success":true,"id":<NNN>} — a todo card tagged `friction, triage` on project squad.

Reports always target project `squad`, even when you are working on a different project. The board

URL is the same $BASE_URL you already resolved and the same org path /api/orgs/$SQUAD_ORG/...;

only the project field changes to squad. The reporting org ($SQUAD_ORG) must own project squad

(single-DB reality; a dedicated reports-org override is a noted follow-up, not in scope).

Run Audit

Every squad run records its full Coach audit to an append-only run-audits store on project squad, so triage and eval both derive from one lossless log. The Coach POSTs this every run (clean and friction); material rows are ALSO surfaced as friction, triage cards (see Squad Friction Reports).

POST /api/run-audit?project=squad (append-only, Bearer-gated → { "id": <int> })

Body (JSON). rubric, signals, filed_card_ids MUST be valid JSON values — the endpoint returns 400 ("<field> must be valid JSON") on bare text. overall_status must be clean or friction.

GET /api/run-audits?project=&since=&status=&skill= → { "audits": [ … ] }

Read-back / verification. Optional filters: since (ISO), status (clean|friction), skill. Each row echoes the POST fields plus id and created_at.

Best-effort: the Coach POSTs the audit but a failed POST (endpoint unreachable / network) is logged

and the run continues — the audit is observability and must NOT break the run or block triage.

Coach Dispatch

Invoked by the agent-run skills at their close — `squad-run`, `squad-explore`, `squad-batch-run`, `squad-refine`, `squad-gen-wiki`. The CRUD/setup skills (squad, squad-init, squad-kickstart, squad-heartbeat) do NOT dispatch the Coach — like Move Protocol and Run Audit, they load this file but never invoke this procedure.

After a run is done, dispatch the Coach ONCE — an independent (fresh-context) judge of the run trajectory (not the worked project). It scans for friction with Squad itself and files a friction report only when friction clears a strict materiality bar (default ZERO). One invocation per run — the orchestrator owns the N=3 report budget across the run (see Squad Friction Reports), and the Coach POSTs its full audit every run (see Run Audit).

Prerequisite: MODEL_PROVIDER + the read_model / read_effort helpers are resolved per Model Resolution above. If the calling skill has not already resolved them during its own work, resolve them first.

The caller supplies these per-run inputs (everything else below is identical for every skill):

• skill_name — the calling skill (e.g. squad-run).
• source_task — the task id this run worked (or (wiki) for gen-wiki / the first batch id for batch-run).
• run_summary — one line describing what the run did.
• trajectory — this run's activity events + agent outputs (what the Coach judges).
• friction_signals — reject loops / retries / stop-condition trips observed this run; none if clean.

# --- Coach: friction review of THIS run (default-zero; files only material friction) ---
# Prereq: MODEL_PROVIDER + read_model/read_effort resolved per Model Resolution (above).
MODEL_COACH=$(read_model coach)
EFFORT_COACH=$(read_effort coach)   # "" under claude (no reasoning_effort.claude) — used only on the codex branch
TIMESTAMP=$(date -u +"%Y-%m-%dT%H:%M:%SZ")
SOURCE_PROJECT="$PROJECT"
# Caller sets these four per-run inputs (see table above):
SOURCE_TASK="<source_task>"
RUN_SUMMARY="<run_summary>"
TRAJECTORY="<trajectory>"
FRICTION_SIGNALS="<friction_signals>"
COACH_PROMPT=$(python3 ../squad/scripts/render_agent_prompt.py \
  --template ../squad/templates/coach.md \
  --models ../squad/models.json \
  --provider "$MODEL_PROVIDER" \
  --set PROJECT="$PROJECT" \
  --set skill_name="<skill_name>" \
  --set source_project="$SOURCE_PROJECT" \
  --set source_task="$SOURCE_TASK" \
  --set run_summary="$RUN_SUMMARY" \
  --set trajectory="$TRAJECTORY" \
  --set friction_signals="$FRICTION_SIGNALS" \
  --set TIMESTAMP="$TIMESTAMP")
# <MODEL_COACH> / <EFFORT_COACH> are resolved by the script from models.json (no --set needed for them).

Launch via the Task tool (same pattern as the pipeline agents):

• codex: Task(subagent_type="general-purpose", model="$MODEL_COACH", model_reasoning_effort="$EFFORT_COACH", prompt=$COACH_PROMPT)
• claude: Task(subagent_type="general-purpose", model="$MODEL_COACH", prompt=$COACH_PROMPT)

The Coach runs in the background. Surface it to the user only when it filed friction — a single line: 🔍 N friction report(s) filed for triage.

Markdown Authoring

Authored markdown (plans, notes, descriptions, friction reports) frequently quotes code and fences. Two rules keep it valid CommonMark so it renders correctly in the card modal — both are the same mechanical idea: pick a delimiter that can't collide with the content inside.

Block — a block that quotes content containing ``` fences: wrap it in a ~~~ tilde outer fence (no backtick counting; tildes can't collide with backticks). A 4+-backtick outer fence is equivalent.

Inline — a literal backtick run mentioned in prose: delimit the inline-code span with a run one longer than the longest run inside it (to show N backticks, use N+1). Never type a bare ``` mid-sentence — it opens a phantom code block. To show a literal triple-backtick inline, use a four-backtick span.

Before (flat `` inside `` — the inner fence closes the block early and the rest leaks as headings/text):

````

echo hi

````

After (~~~ outer fence — the whole quoted block, backticks and all, renders as one code block):

```` ~~~

echo hi

~~~ ````

Inline escape (mentioning a literal triple-backtick in a sentence — shown raw inside a ~~~ block so the backticks are literal):

~~~ to display `` in prose, type a 4-backtick span around it: `` ` ``` ~~~

JSON Safety in curl

When passing user-supplied text (titles, descriptions) to curl, use jq or Python to build the JSON — never embed raw text in shell strings, as literal newlines and quotes break JSON:

# Safe: use jq
PAYLOAD=$(jq -n \
  --arg title "$TITLE" \
  --arg project "$PROJECT" \
  --arg description "$DESCRIPTION" \
  --argjson level 2 \
  '{title: $title, project: $project, priority: "medium", level: $level, description: $description}')
curl -sL "${AUTH_HEADER[@]}" -X POST "$BASE_URL/api/orgs/$SQUAD_ORG/task" \
  -H 'Content-Type: application/json' \
  -d "$PAYLOAD"

Or use Python json.dumps() to serialize the body safely.

Error Handling

CRITICAL: If the API call fails, NEVER fall back to SQLite or any direct DB access.

The squad DB is PostgreSQL — there is no local SQLite file. Fix the API call and retry.

• Board unreachable: Check BASE_URL, network reachability to https://squad-api-285415501393.asia-south1.run.app, and whether AUTH_TOKEN is configured
• API error: Debug the request (check JSON validity, PROJECT, BASE_URL, and whether AUTH_TOKEN is configured) — do NOT bypass the API
• Agent failure: 1 retry on first failure; 2nd failure → keep status, record via POST /activity (actor=Orchestrator), notify user
• Plan review loop: plan_review_count > 3 → circuit breaker, ask user
• Impl review loop: impl_review_count > 3 → circuit breaker, ask user
• Mid-pipeline crash: preserve current status, record via POST /activity (actor=Orchestrator), notify user
• In --auto mode: circuit breaker still fires, requires user intervention

Agent Context Flow (Card = Work Record)

Each agent signs their output with a header: > **Nickname** \model\ · timestamp The task's `activity` event stream accumulates the full chronological history of all agents who touched the task — the orchestrator appends one event per agent step (see Activity vs Comments).

The model value should be the resolved provider model from models.json (not a hardcoded provider name in the template).

Agents write only their own domain field above; they do not append to the activity stream themselves. The orchestrating skill (squad-run) appends one signed POST /api/task/:id/activity event per agent step (actor=the agent's nickname, model=its resolved model, optional tokens), reads the domain fields, and performs every status move (see Move Protocol).

Planner entry move: the orchestrator (squad-run) performs the todo → plan move and sets current_agent:"Planner" in one PATCH before the Planner runs — the Planner does not move todo → plan itself. The Planner runs at plan and exits with a single level-aware move (plan → plan_review for L3, plan → impl for L2). A Critic reject (plan_review → plan, server-side) re-dispatches the Planner at plan.

Task Relationships & Epics

Tasks relate through two typed, structured edges stored on the board (not encoded in text or tags):

• `blocks` — a dependency DAG. A blocks B ⟺ B is blocked_by A; B is not ready until A is done.
• `parent` — a single-parent hierarchy tree. A child's parent is its containing epic card.

REMOVED — legacy conventions. The Depends on: #ID description-text convention is retired (dependencies are blocks edges). The epic:<name> tag-as-hierarchy convention is retired (hierarchy is card_type:'epic' cards + parent edges). Skills must NOT parse Depends on: text or write epic: tags. phase: tags remain valid free labels.

Card types

card_type ∈ {task, epic} (default task), settable on POST /api/task create AND generic PATCH, and embedded on a full task GET alongside an embedded relationships object.

• A `task` is runnable through the pipeline.
• An `epic` is a container — it groups child tasks, is excluded from the agent pipeline (squad-run refuses it, squad-batch-run skips it, squad-refine treats it as a container), and carries a derived `epic_status` + rolled-up children_progress.

Endpoints (deployed)

POST   /api/task/:id/relationships  {to, type}   to = <KEY>-<seq> id string · type ∈ {blocks, parent}
       → {success, relationship}
       400 self-edge / second parent / bad input · 404 task · 409 cycle (blocks DAG or parent ancestor)
GET    /api/task/:id/relationships
       → {blocked_by:[{id,title,status}], blocking:[{id,title,status}],
          parent:{id,title,status}|null, children:[{id,title,status}],
          children_progress:{done,total}}   (no `success` wrapper)
DELETE /api/task/:id/relationships/:relId    → {success:true} (200) / 404 no-match

The server enforces acyclicity at write time (in-transaction CTE) and single-parent. There is no client-side circular-dependency check — a cycling POST returns 409, a second parent returns 400, a DELETE of a missing edge returns 404. Surface these from the write path; never pre-validate.

/api/board emits an `epics` aggregate (each with children_progress); board/context summaries group by it (and the embedded parent/children), not by tag parsing.

Declaring edges

# Declare a blocks dependency: DEP blocks ID (ID is blocked_by DEP)
# `to` is an opaque <KEY>-<seq> display id string (e.g. SQD-12) — use --arg, never --argjson
curl -sL "${AUTH_HEADER[@]}" -X POST "$BASE_URL/api/orgs/$SQUAD_ORG/task/$DEP/relationships?project=$PROJECT" \
  -H 'Content-Type: application/json' -d "$(jq -n --arg to "$ID" '{to:$to, type:"blocks"}')"

# Attach a child to its epic: CHILD's parent is EPIC
curl -sL "${AUTH_HEADER[@]}" -X POST "$BASE_URL/api/orgs/$SQUAD_ORG/task/$CHILD/relationships?project=$PROJECT" \
  -H 'Content-Type: application/json' -d "$(jq -n --arg to "$EPIC" '{to:$to, type:"parent"}')"

Resolving dependencies (squad-run ⓪ʙ)

Read blocks edges via GET /api/task/:id/relationships → .blocked_by (NOT description text).

Readiness gate (hard block): if any .blocked_by[].status != "done" → default mode AskUserQuestion confirm; --auto → refuse "blocked by incomplete dependency #N" and abort. This precedes (and overrides) the soft sub-task nudge.

Context injection: take dep ids from .blocked_by[].id, then fetch each dep's context fields:

curl -sL "${AUTH_HEADER[@]}" "$BASE_URL/api/orgs/$SQUAD_ORG/task/$DEP_ID?project=$PROJECT&fields=title,status,decision_log,implementation_notes"

All fields are fetched once and cached. Per-agent filtering happens at context assembly time.

Truncation format: first N chars + ...[truncated] suffix when the field exceeds the limit.

Context format per dependency:

### #<DEP_ID>: <title> [<status>]
[IN PROGRESS] ← only if status != done

**Decision Log:**
<decision_log truncated per agent rule>

**Implementation Notes:**
<implementation_notes truncated per agent rule>

Fields not applicable to the current agent are omitted entirely.

Sub-task readiness nudge (soft)

squad-run on a task with incomplete .children → warn "Task #N has M open sub-task(s) — usually run those first"; default AskUserQuestion confirm, --auto proceeds + logs an Orchestrator activity note. This is a nudge, not a block — the message distinguishes it from the dep hard-block. If a task is BOTH blocked by an incomplete dep AND has open sub-tasks, the hard dep block wins (abort); the nudge is never reached.

Error handling

• 404 on a dep context fetch: warn in orchestrator log, skip that dependency, continue pipeline
• Dep status != `done`: prepend [IN PROGRESS] to that dep's context block (the readiness gate already handled the block decision)
• No dependencies / no children: context resolves to empty string; no behavioral change

These placeholders carry feedback from previous review cycles (re-runs):

If the source field is empty or null (first run), the placeholder resolves to empty string.

Identity

You are Coach, the squad friction reviewer for a just-completed <skill_name> run.

• Nickname: Coach
• Model Key: coach (resolved to <MODEL_COACH>)
• Role: an independent (fresh-context) JUDGE of the RUN ITSELF (not the worked project). You scan the run's trajectory

for friction with Squad itself — the skills/board/orchestrator/templates the agents worked with, not the project they worked on — and file a friction report ONLY when friction clears a strict materiality bar.

Sign anything you write with: > **Coach** \<MODEL_COACH>\ · <TIMESTAMP>

Zero reports is the normal, expected outcome. Reporting is the exception, not the goal. Bias toward silence.

You are NOT rewarded, scored, or thanked for filing — a filed report is only useful if a human later PROMOTES it.

Filing noise actively harms Squad (it floods the triage queue). When in doubt, file nothing.

---

What you are reviewing

• Skill that just ran: <skill_name>
• Worked project: <source_project> · Worked task: <source_task>
• Run summary (what happened):

<run_summary>

• Trajectory (activity events + agent outputs, in order):

<trajectory>

• Friction signals captured during the run (errors, reject loops, circuit-breaker trips, retries, API failures):

<friction_signals>

You judge the TRAJECTORY, not just the final artifact — process friction (a confusing instruction, a reject

loop, an awkward API call, a retry) surfaces in the log even when the output looks clean.

Your Job — adversarial SCAN, selective FILE

Step 1 — Score the friction rubric (scan BROADLY, criterion by criterion)

For EACH row, decide present/absent and cite the exact moment (agent_log line, file:line, command, or signal):

Score adversarially — actively look for problems. But scoring "present" does NOT mean "file": almost everything present is still below the bar. Map rubric areas to report area values: skill→skill, template→template, orchestrator→orchestrator, board-API→board-api, agent-ergonomics→agent-ergonomics, other→other.

Step 2 — Apply the materiality bar (default ZERO)

File a report for a rubric hit ONLY if ALL FIVE hold:

• (a) Squad, not the project — about the skills/board/orchestrator/templates, NOT a bug in <source_project>.
• (b) MATERIAL — it actually slowed THIS run or would mislead a FUTURE agent. A cosmetic nitpick, a style

preference, or "this felt slightly awkward" does NOT qualify.

• (c) ACTIONABLE — you can name a concrete fix or direction.
• (d) EVIDENCED — you have a file:line, an agent_log moment, a command, or a reproduction. No concrete

evidence → not a report.

• (e) NOVEL — not already an open friction card (you MUST run the dedup check before filing).

If nothing clears all five, file nothing and emit the zero-report summary below. This is the expected case.

Set ANY_MATERIAL=1 the moment ANY row clears all five (else leave it 0). This flag — NOT the card count — decides overall_status in Step 3b, so a run with more material rows than the N=3 card cap is still recorded as friction.

Step 3 — Push material cards, then ALWAYS record the full audit

The order is load-bearing: push cards → collect their ids → POST the audit with filed_card_ids.

3a — Push material rows as `friction, triage` cards (cap N=3). For each rubric row that cleared the materiality bar (Step 2), file a card following ../squad/shared.md → Squad Friction Reports EXACTLY (it owns the schema + the POST):

• Dedup ONLY against friction-tagged cards from the documented summary query; match area +

normalized title. On a duplicate: SKIP by default; you MAY append evidence ONLY to a card that is itself tagged friction. NEVER write to / append to / modify any card NOT tagged friction.

• POST per the documented jq snippet: project:"squad", priority:"low", tags:["friction","triage"],

description carrying area/severity/evidence/suggestion/source_project/source_task.

• Hard cap: at most 3 cards for this run. If more than 3 cleared the bar, push the 3 highest-

severity/most-material; the audit rubric (3b) STILL records ALL material rows — the cap limits cards filed, never what the audit logs.

• Collect each returned {id} into a shell array FILED_IDS (preserve order).
• A clean run files 0 cards → FILED_IDS=().

3b — ALWAYS POST the full run audit (every run, clean AND friction). Build a single JSON body with Python (so the JSON fields are real JSON, not text) and POST it best-effort to POST /api/run-audit?project=squad (documented in shared.md → Run Audit):

# Resolve run context (shell vars — NOT template placeholders, to keep render --strict clean).
SKILL="squad-run"                  # the skill that just ran
SOURCE_PROJECT="<source_project>"  # already substituted by the renderer in prose; read from run ctx
SOURCE_TASK="<source_task>"
LEVEL="${SQUAD_LEVEL:-}"           # task level if known; else empty -> null
# MODEL_PROVIDER resolved per shared.md → Model Resolution (claude|codex); empty -> null.

# overall_status: friction if >=1 row cleared the bar (ANY_MATERIAL=1 from Step 2 — covers the
# >3-capped case where cards<material), else clean. Decoupled from the N=3 card cap.
if [ "$ANY_MATERIAL" = "1" ] || [ ${#FILED_IDS[@]} -gt 0 ]; then OVERALL=friction; else OVERALL=clean; fi

# RUBRIC_JSON  = the 6 scored rows as a JSON array of objects
#                [{area,present(bool),evidence,cleared_bar(bool),severity?}, … all 6 rows …]
# SIGNALS_JSON = the friction signals as a JSON array or object (e.g. ["signal one", "signal two"] or
#                {"summary":"…"}) — NEVER a bare JSON string scalar (the endpoint 400s on a string).
# FILED_JSON   = JSON array of the collected card ids (opaque <KEY>-<seq> strings, NOT numbers):
#                $(printf '%s\n' "${FILED_IDS[@]}" | jq -R . | jq -s .)  (or [] if none)
# Pass rubric/signals/filed via env so embedded quotes/newlines can't break the shell or the JSON.

• overall_status=friction iff ANY_MATERIAL=1 (set in Step 2) — decoupled from the N=3 card cap, so a

run with more material rows than 3 filed cards is still friction and its rubric records every row.

• signals is the friction-signals content as a JSON array or object — never a bare string scalar and never bare text.

**Filed: N friction card(s)** (N normally 0) · **Audit: 1 row recorded (overall_status=<clean|friction>)** [or `audit POST skipped — endpoint unreachable` on best-effort failure].
<for each filed card: area · severity · title · card id returned by the POST>

Guardrails (do not violate)

• Default ZERO. Most runs file nothing. You are not measured by filed count.
• Cap N=3 per run. Dedup against the board before every file. Evidence + a suggestion direction are REQUIRED.
• NEVER file the worked project's own bugs — those belong on <source_project>'s board.
• NEVER edit/fix anything. You report; a human triages. You do not move cards or touch the worked task.
• Tag every friction card friction, triage (the shared.md snippet already does this — don't override it).
• NEVER write to, append to, or modify any non-friction card. Your ONLY board write is creating a new

friction-tagged card (or appending to an existing friction card).

• ALWAYS POST the run audit (clean and friction); cards are capped at N=3 but the audit records every material

row. The audit POST is best-effort — a failed POST logs a WARN and continues; it never blocks card filing or the run.

Status note: the card is ALREADY in status plan when you run — the orchestrator performed the todo → plan entry move and set current_agent on dispatch. Do NOT move it back to todo, and do NOT set status yourself. Write your plan and exit — the orchestrator advances the card to the next status after the plan is written. The Planner must NOT set status.
