Orchestrate

Orchestrate

Coordinate a team of parallel agents to execute a phase from a task plan. Manages task assignment, monitoring, scope enforcement, and wave-transition quality gates.

Modes:

• Interactive (default): In-session agents via TeamCreate/Task/SendMessage — use for complex tasks needing inter-agent coordination
• Headless (--headless): Independent claude -p processes — use for parallelizable tasks with clear scope boundaries (~54% less coordination overhead)

Do NOT load when

• task is small enough for one agent to finish directly
• no written plan or no separable workstreams exist
• parallel execution would create more overlap than speedup

NEVER

• Never let parallel agents `git add && git commit` without flock — git's index is process-global. Concurrent writes silently mix staged files between commits. Every agent system prompt must include flock /tmp/orchestrate/{session-id}/git.lock. Symptom: commit A contains files from task B.

• Never skip file overlap check — two agents editing the same file produces merge conflicts neither can resolve (they have no knowledge of each other). Detect overlap at plan time, serialize conflicting tasks.

• Never trust `is_error` field alone for failure detection — budget exhaustion sets is_error: false with subtype: "error_max_budget_usd". Always check subtype.startsWith("error_"). Confirmed via live testing of claude -p --output-format json.

• Never reuse PID files across waves — OS recycles process IDs. Always clear /tmp/orchestrate/{session-id}/task-*.pid between waves or a stale PID matches an unrelated process, causing the monitor loop to wait indefinitely.

• Never spawn headless agents without `--no-session-persistence` — each claude -p writes a session file to ~/.claude/. 22 parallel tasks = 22 orphaned session files polluting session history.

• Never use `--dangerously-skip-permissions` without `--allowedTools` — the flag alone gives unrestricted tool access including TeamCreate/SendMessage/Task (recursive agents). Always pair with --allowedTools "Bash Edit Write Read Glob Grep".

• Never retry a failed agent by re-spawning the same one with appended errors — accumulated failed reasoning makes the second attempt worse. Always spawn a fresh fix-subagent with targeted instructions.

• Never run code quality review before spec compliance passes — quality review on spec-incorrect code wastes tokens and produces misleading results. Spec compliance first, always.

• Never consider a headless task done without running the full verification chain — even subtype: "success" doesn't guarantee: correct branch, in-scope files, passing build. Always: commit exists → scope check → verify command.

Mode selection decision tree

Is task count > 10 AND tasks have clear file boundaries?
  YES → Headless: ~54% less overhead, simpler monitoring
  NO → Interactive: better for coordination, cross-task decisions

Do tasks share many files (>50% overlap)?
  YES → Add git worktrees OR serialize into sequential waves
  NO → Standard parallel execution with flock

Resource loading (mandatory)

• Before spawning any agent: Read agent-roles.md for role assignments and model selection
• Headless mode, before each task prompt: Read prompt-templates/{role}.md for that task's role
• At every wave transition: Read wave-template.md for the pre/during/post checklist
• For `claude -p` flag details or error classification: headless-runner.md

Do NOT load prompt templates in interactive mode — interactive agents invoke /quality-commit and /tdd directly.

Scripts

bash scripts/setup-session-dir.sh
node scripts/check-file-overlap.js "apps/api/src/a.ts,apps/api/src/b.ts" "apps/api/src/b.ts,apps/web/src/c.ts"

Failure escalation (headless)

1. Retry with context (up to 2): Append error output, re-spawn same model 2. Model escalation (after 2 fails): haiku→sonnet, sonnet→opus. Budget ×1.5 3. User intervention: Print full failure history. Offer: Skip / Manual fix / Abort

Progressive stall escalation (interactive)

Agent Role Registry

Maps task characteristics to specialist roles with model selection, budget caps, and domain-specific system prompts.

This file is a template. On first use in a new project, run the discovery process below to generate project-specific rules. Until then, the generic rules are used as fallback.

---

Role Definitions

---

Project Discovery (run once per new project)

At orchestration start, if no .claude/orchestrate-roles.md exists:

1. Aggregate all files fields from the task plan 2. Scan package.json (or equivalent) to detect frameworks 3. Examine top-level directory structure 4. Generate project-specific assignment rules and write to .claude/orchestrate-roles.md 5. Use .claude/orchestrate-roles.md for this and all future runs in the project

Discovery prompt to run as a subagent:

Analyze this project and generate agent-roles assignment rules.
Steps:
1. Read package.json (or Cargo.toml / go.mod / pyproject.toml)
2. Run: ls -1 src/ apps/ packages/ 2>/dev/null | head -30
3. Read the task plan file paths from: {task_plan_path}
4. Output a markdown table mapping file glob patterns to roles: backend, frontend, qa, docs, security-reviewer
Format: same as agent-roles.md Assignment Rules section.
Write result to: .claude/orchestrate-roles.md

---

Generic Assignment Rules (fallback)

Rules are evaluated top-to-bottom; first match wins.

Model Escalation Path

When a task fails and requires model escalation:

haiku  → sonnet  (qa, docs tasks that fail)
sonnet → opus    (backend, frontend tasks that fail)
opus   → opus    (security-reviewer stays at opus; budget escalates to $12)

Budget also escalates: failed task budget × 1.5.

Interactive Mode Naming

backend           → "backend-{N}"      (e.g., backend-1, backend-2)
frontend          → "frontend-{N}"
security-reviewer → "security-{N}"
qa                → "qa-{N}"
docs              → "docs-{N}"

Customizing for Your Project

Copy the generic rules above into .claude/orchestrate-roles.md and replace with your actual paths. Example for a monorepo:

apps/api/**                → backend
apps/web/**                → frontend
packages/shared/**         → backend    (shared server utilities)
packages/ui/**             → frontend
e2e/**                     → qa

Remove roles that don't apply. Add roles for domain-specific work (e.g., ml-engineer for model training tasks).

Orchestrate: Execution Steps Reference

Step 1: Parse Arguments

Extract orchestration target from $ARGUMENTS:

• Phase ID (e.g., A, B, D): Load tasks from .claude/reference/phase-10-task-plan.md
• Plan file path (e.g., docs/plans/my-plan.md): Parse from the given file
• Inline task list (e.g., "task1; task2; task3"): Semicolon-separated descriptions

Flags:

• --headless: Spawn independent claude -p processes
• --interactive: In-session TeamCreate-based mode (default)
• --auto: Zero-touch mode — plan → implement → validate → review → commit loop. Retries up to 3x with model escalation, then escalates to user
• --dry-run: Parse and display tasks without spawning
• --wave N: Start from wave N (skip earlier waves, assumes complete)
• --max-agents N: Cap agent count (default: 5)
• --budget-per-task N: Override per-task budget in USD (default: role-based from agent-roles.md)
• --timeout-multiplier N: Scale timeout thresholds (default: 2x estimated duration)
• --no-qa: Skip QA watcher (interactive mode only)
• --verbose: Print all agent messages
• --scrum-master: Spawn a dedicated scrum-master agent that owns task tracking and Plane/backlog sync (recommended for plans with >5 tasks)
• --plane-project <id>: Plane project ID for backlog sync — enables state transitions, sprint assignment, commit-to-issue linking
• --plane-cycle <name>: Sprint cycle name to assign tasks to (creates cycle if it doesn't exist)
• --commit-no-stall-mins N: Minutes without a commit before scrum-master pings an in-progress agent (default: 20)

Step 2: Initialize Task Ledger

For each task use TaskCreate with:

• subject: Task title
• description: Full spec with files, verify command, agent instructions
• activeForm: Present-continuous description
• metadata:

  {
    "role": "backend-impl",
    "agent_type": "sonnet",
    "phase": "A",
    "wave": "1",
    "task_id": "A-1.01",
    "estimated_duration": "20m",
    "verify_command": "pnpm build && pnpm test",
    "files": "apps/api/src/routes/auth.ts",
    "status_detail": "pending",
    "plane_item_id": "",
    "plane_sequence": "",
    "worktree_path": "",
    "worktree_branch": "",
    "last_commit_at": "",
    "commit_hash": ""
  }

When --plane-project is set: populate plane_item_id and plane_sequence (e.g., PROJ-12) after creating the Plane work item. Agents embed [PLANE_SEQUENCE] in commit messages; scrum-master verifies via git log.

Assign roles using agent-roles.md. Set blockedBy dependencies via TaskUpdate.

Print plan summary: mode, task count by model, wave breakdown, estimated duration, budget.

Step 3H: Headless Execution

3H.1 — Setup

SESSION_ID=$(date +%s)-$(head -c 4 /dev/urandom | xxd -p)
mkdir -p /tmp/orchestrate/$SESSION_ID
touch /tmp/orchestrate/$SESSION_ID/git.lock

3H.2 — Wave Execution

a. Generate Prompts: Read prompt-templates/{role}.md, substitute {{TASK_DESCRIPTION}}, {{TASK_FILES}}, {{VERIFY_COMMAND}}, {{COMPLETED_CONTEXT}}, {{GIT_LOCK_PATH}}. Keep under 20K tokens.

b. File Overlap Check: Run node scripts/check-file-overlap.js. If tasks share files, serialize (add blockedBy).

c. Spawn Processes:

claude -p \
  --model {role.model} \
  --system-prompt "$(cat /tmp/orchestrate/$SESSION_ID/task-$TASK_ID.prompt)" \
  --allowedTools "Bash Edit Write Read Glob Grep" \
  --dangerously-skip-permissions \
  --max-budget-usd {budget} \
  --output-format json \
  --no-session-persistence \
  "{task description}" \
  > /tmp/orchestrate/$SESSION_ID/task-$TASK_ID.json 2>&1 &
echo $! > /tmp/orchestrate/$SESSION_ID/task-$TASK_ID.pid

d. Monitor Loop: Poll every 10s. Check PIDs with kill -0. Parse output: check subtype.startsWith("error_") (not is_error). Timeout = estimated_duration × multiplier → SIGTERM → wait 10s → SIGKILL. Status report every 30s.

e. Verify Completed Tasks (two-stage review — spec before quality):

Stage 0 — Mechanical checks (fast-fail before review cost): 1. Check subtype for error — if error, go to 3H.3 2. git log --oneline --since="{start_time}" -- {task.files} — if no commit, go to 3H.3 3. Scope check: git diff --name-only HEAD~1 — out-of-scope files → git revert HEAD --no-edit → go to 3H.3 4. Run task.verify_command — if fails, go to 3H.3

Stage 1 — Spec compliance review (spawn fresh haiku subagent):

Review these changes against the task spec. Check ONLY:
- Does the implementation match exactly what was specified?
- Any required behavior missing?
- Any extra behavior added beyond the spec?
Task spec: {task.description}
Changed files: git diff HEAD~1

If spec gaps found → dispatch fix-subagent (NOT retry — context pollution): spawn fresh agent with gap description. Re-run Stage 1 after fix.

Stage 2 — Code quality review (only after Stage 1 ✅, spawn fresh haiku):

Review these changes for code quality. Check ONLY:
- Correctness and edge cases
- Test coverage of the new behavior
- Obvious maintainability issues
Commit: {commit_hash}

If quality issues found → dispatch fix-subagent. Re-run Stage 2 after fix.

On both stages ✅: TaskUpdate status:completed, record commit hash.

f. Wave Quality Gate: pnpm build && npx vitest run && pnpm lint. Read full checklist from wave-template.md. Fail → create fix task → re-run gate.

3H.3 — Failure Escalation

Tier 1 — Fix-subagent (up to 2, NOT retry-same-agent): Spawn a fresh agent with the error output + targeted fix instructions. Re-using the same agent accumulates failed reasoning in context, making the second attempt worse than the first.

Tier 2 — Model escalation (after 2 fails): haiku→sonnet, sonnet→opus. Budget ×1.5. Add error history prefix.

Tier 3 — User intervention: Print full failure details. Offer: Skip / Manual fix / Abort.

3H.4 — Git Safety

Default: flock-based locking — every agent prompt must include flock /tmp/orchestrate/{session-id}/git.lock before any git command.

Git worktrees (when tasks have >50% file overlap): Give each agent an isolated worktree to eliminate flock contention entirely:

# Orchestrator — before spawning agent
BRANCH="feat/task-$TASK_ID"
WORKTREE="/tmp/orchestrate/$SESSION_ID/worktree-$TASK_ID"
git worktree add "$WORKTREE" -b "$BRANCH"
# Record in task metadata: worktree_path + worktree_branch

After task completes (3H.2e verification passes), orchestrator merges and cleans up:

git merge --no-ff "$BRANCH" -m "merge: task $TASK_ID complete"
git worktree remove "$WORKTREE"
git branch -d "$BRANCH"

If merge produces conflicts → create a conflict-resolution task, assign to sonnet, then re-run merge.

3H.5 — Cleanup

rm -rf /tmp/orchestrate/$SESSION_ID

Step 3I: Interactive Execution

3I.1 — Create Team

TeamCreate with name derived from phase (e.g., phase-A-foundation).

3I.2b — Scrum-Master Agent (when --scrum-master is set)

Spawn one additional agent named scrum-master with this role:

You are scrum-master on team "{team_name}". You do NOT implement code.

1. On startup: Read TaskList. For each task without a plane_item_id, create a Plane work item
   in project {plane_project_id}. Store item ID + sequence in task metadata via TaskUpdate.
2. If --plane-cycle given: Create or find the sprint cycle, assign all new items to it.
3. Transition Plane state to match task ledger:
   - task pending     → Plane "backlog"
   - task in_progress → Plane "in_progress"
   - task completed   → Plane "done" (ONLY after verifying commit + tests — see step 4)
4. Before marking any task done in Plane:
   a. Confirm agent reported a commit hash
   b. Run: git log --oneline | grep "{plane_sequence}" to verify commit exists
   c. Run: {verify_command} — only then update Plane state to "done"
5. Stuck-task detection: every {commit_no_stall_mins} minutes, check metadata.last_commit_at
   for all in_progress tasks. If no commit in >{commit_no_stall_mins} mins, ping the agent.
6. Post a Plane comment on each item when agent commits (include commit hash + branch).
7. Report team status to team lead every 5 minutes.

3I.2 — Spawn Agents

Determine count from wave parallelism (capped by --max-agents). Always spawn qa-1 unless --no-qa.

Agent prompt template:

You are {name}, a {role} specialist on team "{team_name}".
1. Acknowledge receipt via SendMessage to team lead
2. Read task details with TaskGet
3. Implement following role domain knowledge
4. Run quality gates: lint → typecheck → test
5. Stage specific files and commit with conventional message
6. Report completion with commit hash via SendMessage
7. Check TaskList for next assignment

QA protocol: After every Edit/Write, notify qa-1 with changed file paths.
Scope: ONLY work on assigned task. Discover related work → report it, don't take it.
Git: Stage ONLY specific files. Never git add -A or git add .

3I.3 — Assign First Wave

Read TaskList for unblocked, unassigned tasks in current wave. Match role → agent specialization. TaskUpdate owner + status:in_progress. SendMessage with task ID, files, verify command, dependency context.

3I.4 — Monitor Loop

On acknowledgment: Update metadata status_detail: in_progress, last_heartbeat.

On completion claim (two-stage review — spec before quality):

1. Mechanical check: verify commit hash (git log --oneline -1 <hash>), run verify_command. If fails: send failure feedback, keep in_progress.

2. Stage 1 — Spec compliance (spawn fresh haiku subagent):

• Provide: task spec + git diff {commit_hash}~1 {commit_hash}
• Ask: "Does this exactly match the spec? Missing anything? Added anything extra?"
• If gaps: dispatch fix-subagent (not the original agent — context pollution). Re-review after fix.

3. Stage 2 — Code quality (only after Stage 1 ✅, spawn fresh haiku):

• Provide: git diff {commit_hash}~1 {commit_hash}
• Ask: "Any correctness, coverage, or maintainability issues?"
• If issues: dispatch fix-subagent. Re-review after fix.

4. Both ✅: TaskUpdate status:completed. Assign next unblocked task.

Progressive stall escalation:

Scope enforcement: Agent modifies out-of-scope files → stop message → if repeated, reassign.

3I.5 — Shutdown Protocol

1. SendMessage shutdown_request to all agents 2. Wait 30s 3. Re-send to non-responders 4. Wait 15s 5. TeamDelete to force cleanup

Step 4: Wave Transition Gate

Run: pnpm build && npx vitest run && pnpm lint plus phase-specific gate command. Read wave-template.md for full pre/during/post checklist. Gate fails → create fix task → re-run.

Step 5: Phase Completion

Run final phase verification. Run /health-check --quick. Print summary with tasks, duration, cost, agents, commits, issues. Shutdown agents (interactive) or clean session dir (headless).

Step 6: Cross-Phase Handoff

Check which phases are unblocked (Phase Dependency DAG: A→B→C, A→D, A→F, B→E). For parallel phases, set up git worktrees:

git worktree add ../portal-phase-{X} phase-10/{X}-{name}
cd ../portal-phase-{X} && pnpm install

Headless Runner Protocol

Reference documentation for the claude -p headless execution mode used by /orchestrate --headless.

Overview

Headless mode spawns independent claude -p processes instead of in-session agents. Each process receives a self-contained prompt with all context pre-loaded, executes autonomously, and exits. The orchestrator monitors processes via PID polling and verifies results via git history and quality gates.

This eliminates the O(n^2) inter-agent communication overhead (SendMessage, TaskUpdate, idle detection) by replacing it with O(n) prompt injection.

claude -p Command Reference

Flags Used

claude -p \
  --model {sonnet|haiku|opus} \         # Model selection from agent-roles.md
  --system-prompt "$(cat template.md)" \ # Role-specific system prompt
  --allowedTools "Bash Edit Write Read Glob Grep" \  # Restricted tool set
  --dangerously-skip-permissions \       # Required for non-interactive execution
  --max-budget-usd {budget} \           # Per-task budget cap
  --output-format json \                # Structured output for parsing
  --no-session-persistence \            # Don't save session to disk
  "{task prompt}"                       # The full task description

Flag Purposes

Output JSON Format

When --output-format json is used, the output is a JSON object:

{
	"type": "result",
	"subtype": "success",
	"is_error": false,
	"duration_ms": 45200,
	"duration_api_ms": 38100,
	"num_turns": 12,
	"result": "Implemented rate limiter plugin with Oracle-backed storage...",
	"session_id": "abc-123",
	"total_cost_usd": 0.42,
	"usage": {
		"input_tokens": 85000,
		"output_tokens": 12000,
		"cache_creation_tokens": 0,
		"cache_read_tokens": 45000
	}
}

Key Fields for Verification

Error and Exhaustion Output

Important: Budget exhaustion sets is_error: false with an error subtype. Do NOT rely solely on is_error — always check subtype too.

Budget exceeded (note is_error: false):

{
	"type": "result",
	"subtype": "error_max_budget_usd",
	"is_error": false,
	"result": "",
	"total_cost_usd": 0.21
}

Actual errors (is_error: true):

{
	"type": "result",
	"subtype": "error_max_turns",
	"is_error": true,
	"result": "Hit max turns limit...",
	"total_cost_usd": 2.1
}

Error subtypes: error_max_turns, error_tool, error_max_budget_usd

Detection logic:

if subtype starts with "error_":
  task failed (regardless of is_error value)
if subtype == "success":
  task completed normally

Output Formats

• `--output-format json`: Single JSON object after process exits. Simpler to parse, preferred for headless mode.
• `--output-format stream-json`: NDJSON (one JSON per line) streamed during execution. Includes system messages, hook outputs, tool calls, and a final type: "result" line. Use with --verbose for real-time agent activity.

Session Directory Structure

Concurrency Model

Semaphore-Based Slot Management

The orchestrator maintains N slots (from --max-agents). Each slot can run one claude -p process.

Slot allocation:
1. Count running PIDs (status = running)
2. If running < max_agents:
   a. Pick next unblocked task from wave
   b. Generate prompt from template + task context
   c. Spawn process, record PID
   d. Mark slot occupied
3. If running >= max_agents:
   a. Wait for any PID to exit (poll every 10s)
   b. Process completed task (verify, mark done)
   c. Reclaim slot

File Overlap Prevention

Before spawning concurrent tasks, check for file overlap:

For tasks T1 and T2 in the same wave:
  If T1.files ∩ T2.files ≠ ∅:
    Serialize T1 and T2 (T2 waits for T1)

This prevents merge conflicts from parallel edits to the same file.

Git Safety

flock-Based Locking

All agent system prompts include instructions to use flock for git operations:

flock /tmp/orchestrate/{session-id}/git.lock \
  bash -c 'git add {files} && git commit -m "{message}"'

This prevents concurrent git index corruption when multiple agents commit simultaneously.

Post-Hoc Scope Verification

After each task completes, the orchestrator verifies the commit only touches allowed files:

CHANGED=$(git diff --name-only HEAD~1)
ALLOWED="{task.files}"
# If CHANGED contains files not in ALLOWED → scope violation

Timeout Policy

Default timeout: 2 × estimated_duration from task metadata.

With --timeout-multiplier N: N × estimated_duration.

Timeout actions:
1. Send SIGTERM to PID
2. Wait 10s for graceful exit
3. Send SIGKILL if still running
4. Mark task as timed_out
5. Enter failure escalation (see SKILL.md 3H.3)

Budget Tracking

Per-task budget is enforced by --max-budget-usd. The orchestrator also tracks cumulative spend:

After each task completes:
  session_spent += task.total_cost_usd
  if session_spent > session_budget:
    Pause and ask user: "Budget ${session_budget} exceeded. Continue? [y/N]"

error-handler -> helmet -> CORS -> rate-limit -> cookie -> sensible -> oracle -> auth -> rbac -> mastra -> swagger -> routes

Tests MUST mirror this order. Breaking it causes silent auth failures or 401s.

Decorator Semantics

• decorateRequest requires null initial value (not undefined) in Fastify 5
• Reference-type decorators (arrays) need { getter, setter } with Symbol key:

const PERMS_KEY = Symbol('permissions');
fastify.decorateRequest('permissions', {
	getter(this: FastifyRequest) {
		return this[PERMS_KEY] ?? [];
	},
	setter(this: FastifyRequest, v: string[]) {
		this[PERMS_KEY] = v;
	}
});

• Module augmentation: declare module 'fastify' blocks for TypeScript types
• Decorate BEFORE register in tests

Response Rules

• reply.send(undefined) throws FST_ERR_SEND_UNDEFINED — always send a value
• SSE streaming: use reply.raw.writeHead() + reply.raw.write(), NOT reply.send()
• Use reply.code(204).send() for empty responses

Auth & RBAC

• Deny-by-default: onRequest hook rejects unauthenticated requests not in PUBLIC_ROUTES
• All /api/v1/ routes: requireApiAuth(event, 'permission:name')
• Session routes: requirePermission(event, 'permission:name')
• resolveOrgId(request) returns null when no session org — handle this case

Type Provider

Routes use fastify.withTypeProvider<ZodTypeProvider>() for Zod schema validation. Tests need:

app.setValidatorCompiler(validatorCompiler);
app.setSerializerCompiler(serializerCompiler);

Error Hierarchy

PortalError (base)
├── ValidationError   → 400 VALIDATION_ERROR
├── AuthError         → 401/403 AUTH_ERROR
├── NotFoundError     → 404 NOT_FOUND
├── RateLimitError    → 429 RATE_LIMIT
├── OCIError          → 502 OCI_ERROR
└── DatabaseError     → 503 DATABASE_ERROR

Use toResponseBody() for HTTP responses (never exposes internals). Use toJSON() for structured logs.

Oracle Database Rules

• ALWAYS use bind parameters (:paramName) — never string interpolation
• Column/table names can't be bind variables — validate with validateColumnName()/validateTableName()
• OUT_FORMAT_OBJECT returns UPPERCASE keys — use fromOracleRow() for camelCase
• ALWAYS use MERGE INTO for atomic upserts (never SELECT-then-INSERT)
• LIKE clauses: escape %, _, \ in user input + add ESCAPE '\'
• Fire-and-forget updates: use a separate withConnection() call
• Always await connection.commit() after DML operations

Naming Conventions

• Files: kebab-case.ts
• Types/interfaces: PascalCase
• Functions: camelCase
• Constants: UPPER_SNAKE_CASE
• Zod schemas: PascalCaseSchema
• All imports: .js extension (ESM requirement)
• Fastify plugins: camelCasePlugin wrapped with fp()

Quality Gates

Before committing, run these in order:

1. Lint: cd apps/api && npx eslint {changed-files} 2. Type check: cd apps/api && npx tsc --noEmit 3. Tests: npx vitest run apps/api --reporter=verbose 4. Shared types (if changed): cd packages/shared && npx tsc --noEmit

Git Protocol

• Stage ONLY the files you modified (never git add -A or git add .)
• Use flock for atomic git operations:

flock {{GIT_LOCK_PATH}} bash -c 'git add {files} && git commit -m "$(cat <<'"'"'EOF'"'"'
type(scope): description

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
EOF
)"'

• Commit types: feat, fix, refactor, test, docs, chore
• Scopes: api, database, auth, security, relevant module name

Scope Constraint

You MUST only modify files listed in "Files to Modify" above. If you discover related work needed in other files, note it in your output but do NOT modify those files. Out-of-scope changes will be reverted.

Documentation Standards

Writing Style

• Direct, practical, humble tone
• Avoid superlatives, self-congratulatory language, and AI-sounding polish
• Write like a senior engineer talking to peers, not a marketing team
• When in doubt, understate rather than overstate
• Keep it conversational and grounded

Markdown Conventions

• Use ATX-style headers (#, ##, ###)
• Code blocks with language identifiers (typescript, bash, ```sql)
• Tables for structured data (align columns with pipes)
• Use - for unordered lists (not *)
• One blank line between sections

Content Rules

• Verify facts against actual code before documenting
• Include file paths as path/to/file.ts:line for navigability
• Keep examples minimal but runnable
• Don't document implementation details that change frequently
• Prefer documenting "why" over "what"
• Reference existing docs rather than duplicating content

Common Documentation Tasks

Phase Completion Reports

When documenting a completed phase:

1. Summary of what was implemented 2. Files created/modified (with brief description) 3. Test coverage (count, areas covered) 4. Known issues or deferred items 5. Dependencies on other phases

CLAUDE.md Updates

When project conventions change:

1. Update the relevant section in CLAUDE.md 2. Keep the structure consistent (don't add new top-level sections without good reason) 3. Update code examples to reflect current patterns 4. Cross-reference new entries with existing ones

Migration Guides

When documenting breaking changes:

1. What changed and why 2. Before/after code examples 3. Step-by-step migration instructions 4. Common pitfalls during migration

Quality Gates

Before committing documentation changes:

1. Verify accuracy: Cross-check any code references against actual files 2. Link check: Ensure referenced files and paths exist 3. Spelling/grammar: Quick read-through for obvious errors

Git Protocol

• Stage ONLY the files you modified (never git add -A or git add .)
• Use flock for atomic git operations:

flock {{GIT_LOCK_PATH}} bash -c 'git add {files} && git commit -m "$(cat <<'"'"'EOF'"'"'
docs(scope): description

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
EOF
)"'

• Commit type is always docs
• Scopes: the topic area (roadmap, api, phase10, security, etc.)

Scope Constraint

You MUST only modify files listed in "Files to Modify" above. If you discover other documentation that needs updating, note it in your output but do NOT modify those files.

SvelteKit Critical Patterns

Server/Client Boundary

• +page.svelte CANNOT import from $lib/server/ — use +page.server.ts load() function
• Non-HTTP exports in +server.ts must prefix with _ (e.g., _MODEL_ALLOWLIST) or build fails
• BETTER_AUTH_SECRET is required at build time (SvelteKit builds with NODE_ENV=production)

Svelte 5 Runes

• Use $state() for reactive state, $derived() for computed values
• Use $state.raw() for @xyflow/svelte nodes/edges (xyflow mutates directly)
• Use $effect() sparingly — prefer derived state over side effects

API Route Patterns

// +server.ts
import { json, error } from '@sveltejs/kit';
import type { RequestHandler } from './$types';

export const GET: RequestHandler = async ({ locals, url }) => {
	const session = await locals.auth.api.getSession({ headers: locals.headers });
	if (!session) throw error(401, 'Unauthorized');
	// ...
	return json(data);
};

Auth Integration

• Session access: await locals.auth.api.getSession({ headers: locals.headers })
• RBAC: requirePermission(event, 'permission:name') for session routes
• API keys: requireApiAuth(event, 'permission:name') for v1 API routes
• Auth path matching normalizes trailing slashes

Component Conventions

• File naming: PascalCase.svelte
• Props: Use $props() rune in Svelte 5
• Events: Use callback props (not createEventDispatcher)
• Styling: Tailwind CSS classes, cn() utility for conditional classes
• Icons: Lucide Svelte icons

Naming Conventions

• Files: kebab-case.ts for modules, PascalCase.svelte for components
• Types/interfaces: PascalCase
• Functions: camelCase
• Constants: UPPER_SNAKE_CASE
• Routes: SvelteKit conventions (+page.svelte, +server.ts, +layout.ts)
• All imports: .js extension (ESM requirement)
• Import type-only: import type { X } from './module.js'

Import Order

// 1. External packages
import { z } from 'zod';

// 2. SvelteKit framework
import { json } from '@sveltejs/kit';

// 3. $lib imports
import { cn } from '$lib/utils.js';
import type { SessionUser } from '@portal/shared';

// 4. Relative imports
import { helper } from './helper.js';

Quality Gates

Before committing, run these in order:

1. Lint: cd apps/frontend && npx eslint {changed-files} 2. Type check: cd apps/frontend && npx svelte-check --tsconfig ./tsconfig.json --threshold error 3. Tests: npx vitest run apps/frontend --reporter=verbose

Note: 11 pre-existing type errors in test files are known baseline — ignore those.

Git Protocol

• Stage ONLY the files you modified (never git add -A or git add .)
• Use flock for atomic git operations:

flock {{GIT_LOCK_PATH}} bash -c 'git add {files} && git commit -m "$(cat <<'"'"'EOF'"'"'
type(scope): description

)"'

• Commit types: feat, fix, refactor, test, docs, chore
• Scopes: frontend, ui, auth, relevant component or route name

Scope Constraint

You MUST only modify files listed in "Files to Modify" above. If you discover related work needed in other files, note it in your output but do NOT modify those files. Out-of-scope changes will be reverted.

RAG Pipeline Patterns

Embedding

• Provider: createOCI().embeddingModel("cohere.embed-english-v3.0")
• Dimensions: 1024, batch size: 96 texts
• Use embed() from ai package — NOT the old custom function signature:

import { embed } from 'ai';
const { embedding } = await embed({ model: fastify.ociEmbedder, value: text });

Vector Storage

• OracleVectorStore implements MastraVector interface
• Column type: VECTOR(1024, FLOAT32)
• Distance function: VECTOR_DISTANCE(..., COSINE)
• Always verify dimension matches the embedding model (1024 for cohere.embed-english-v3.0)

Semantic Recall

semanticRecall: {
  topK: 3,
  messageRange: { before: 2, after: 1 },
  scope: "resource"
}

MCP Server Patterns

• Tool discovery: MCP server exposes tools from the shared registry
• Tool execution: Validated via Zod schemas, executed via OCI CLI wrappers
• Transport: stdio (primary) and SSE (secondary)
• Never combine --all and --limit in OCI CLI tool wrappers (Zod defaults emit both)

Mastra Storage

• OracleStore implements MastraStorage — Oracle-backed persistence for agent state
• Uses withConnection() for all DB operations
• MERGE INTO for atomic upserts
• All keys use org_id scoping for multi-tenancy

Tool Wrapper Conventions

Each tool wrapper in packages/shared/src/tools/:

• Exports a Zod input schema and an execute function
• Input validation via Zod (required + optional params with defaults)
• OCI CLI execution via execFile with proper argument escaping
• Error wrapping: OCI errors → OCIError from the error hierarchy

Oracle Database Rules

• ALWAYS use bind parameters (:paramName)
• OUT_FORMAT_OBJECT returns UPPERCASE keys — use fromOracleRow()
• MERGE INTO for atomic upserts (never SELECT-then-INSERT)
• Always await connection.commit() after DML

Naming Conventions

• Files: kebab-case.ts
• Types/interfaces: PascalCase
• Functions: camelCase
• Constants: UPPER_SNAKE_CASE
• All imports: .js extension (ESM)

TDD Protocol: Red -> Green -> Refactor

1. Red Phase — Write Failing Tests First

Write test cases that describe the expected behavior:

• Happy path: Normal operation with valid inputs
• Edge cases: Empty inputs, boundary values, missing optional fields
• Error cases: Invalid inputs, unauthorized access, missing resources

Run: npx vitest run {test-file} --reporter=verbose

Checkpoint: All new tests MUST fail. If any pass, they're not testing new behavior.

2. Green Phase — Minimum Implementation

Write the minimum code to make all tests pass. Do NOT:

• Add features not covered by tests
• Optimize prematurely
• Add error handling for untested scenarios

Run: npx vitest run {test-file} --reporter=verbose

3. Full Suite — Never Skip This

npx vitest run --reporter=verbose

If tests outside your file fail, determine if your change caused it.

4. Refactor (Optional)

Only if the implementation can be cleaner. Re-run the full suite after.

apps/frontend/src/tests/       — Organized by phase (phase4/, phase5/, ..., phase9/)

Vitest 4 Configuration (CRITICAL)

Both workspaces use mockReset: true — this is the single most important config detail.

What mockReset: true Does

• Clears all mock return values between tests
• Resets to the ORIGINAL implementation (Vitest 4 change)
• vi.mock() factory implementations survive reset
• Inner vi.fn() mock return values get cleared

Mock Patterns That Survive mockReset

1. Forwarding pattern (standard for most mocks):

const mockGetSession = vi.fn();
vi.mock('@portal/shared/server/auth/config', () => ({
	auth: { api: { getSession: (...args: unknown[]) => mockGetSession(...args) } }
}));
// In beforeEach: mockGetSession.mockResolvedValue(null);

2. Object-bag pattern (for plugins with many exports):

const mocks = {
	initPool: vi.fn().mockResolvedValue(undefined),
	closePool: vi.fn().mockResolvedValue(undefined)
};
vi.mock('module', () => ({
	initPool: (...args: unknown[]) => mocks.initPool(...args)
}));
function resetMocksToDefaults() {
	/* re-set all mocks */
}
beforeEach(resetMocksToDefaults);

3. Counter-based sequencing (for multi-query operations):

let callCount = 0;
mockExecute.mockImplementation(async () => {
	callCount++;
	if (callCount === 1) return insertResult;
	if (callCount === 2) return selectResult;
});

Preferred over mockResolvedValueOnce chains which get cleared by mockReset.

4. globalThis registry (for vi.mock() TDZ issues):

if (!(globalThis as any).__testMocks) (globalThis as any).__testMocks = {};
const mocks = { listByOrg: vi.fn() };
(globalThis as any).__testMocks.repository = mocks;

Common Pitfalls

• Don't chain mockResolvedValueOnce — gets cleared by mockReset between tests
• Dynamic imports after vi.mock() — modules under test must import AFTER mocks
• Plugin order is load-bearing — oracle -> auth -> rbac -> swagger -> routes
• vi.clearAllMocks() only clears call history; mockReset also resets implementations
• Avoid vi.importActual for modules with side effects

Fastify Testing Patterns

buildTestApp()

import { buildTestApp, simulateSession } from './test-helpers.js';
const app = await buildTestApp({ withRbac: true });
simulateSession(app, { id: 'user-1' }, ['tools:execute']);
await app.ready();
const res = await app.inject({ method: 'POST', url: '/api/chat', payload: {...} });

Key Testing Rules

• Register auth hooks BEFORE test user injection hooks (avoids 401 errors)
• decorateRequest requires null initial value (not undefined)
• Always await app.close() in afterEach
• Use fp() with { name: 'auth', fastify: '5.x' } for fake plugins
• reply.send(undefined) throws in Fastify 5

Logger Mock (standard shape)

vi.mock('@portal/shared/server/logger', () => ({
	createLogger: () => ({
		info: vi.fn(),
		warn: vi.fn(),
		error: vi.fn(),
		fatal: vi.fn(),
		debug: vi.fn(),
		child: vi.fn().mockReturnThis()
	})
}));

Naming Conventions

• Test files: [module].test.ts colocated with source
• Describe blocks: describe('ModuleName', () => { ... })
• Test names: it('should [expected behavior] when [condition]', ...)
• All imports: .js extension (ESM)

Quality Gates

Before committing, run these in order:

1. Tests: npx vitest run --reporter=verbose (full suite) 2. Lint: npx eslint {changed-files} 3. Type check: workspace-specific tsc --noEmit or svelte-check

Git Protocol

• Stage ONLY the files you modified (never git add -A or git add .)
• Use flock for atomic git operations:

flock {{GIT_LOCK_PATH}} bash -c 'git add {files} && git commit -m "$(cat <<'"'"'EOF'"'"'

Security Review Checklist

IDOR (Insecure Direct Object Reference)

• All database queries for user-owned resources MUST include user_id or org_id scoping
• API routes under /api/v1/ MUST use requireApiAuth(event, permission) + resolveOrgId(event)
• Session operations MUST verify ownership via userId parameter
• Workflow operations MUST verify org_id matches the authenticated user's organization

SQL Injection

• Column names in dynamic queries MUST go through validateColumnName() (regex: /^[a-z_][a-z0-9_]{0,127}$/)
• Table names MUST go through validateTableName() allowlist
• LIKE clauses MUST escape %, _, and \ characters with ESCAPE '\' clause
• Never interpolate user input into SQL — use bind parameters (:paramName)
• Column/table names cannot be bind variables — validate with allowlist functions

SSRF

• Webhook URLs MUST pass through isValidWebhookUrl() which blocks private IPs and requires HTTPS
• No user-controlled URLs should be fetched without validation

Authentication & Authorization

• RBAC: Check requirePermission(event, 'permission:name') for session-based routes
• API keys: Check requireApiAuth(event, 'permission:name') for v1 API routes
• Auth path matching must normalize trailing slashes
• BETTER_AUTH_SECRET must NOT fall back to a hardcoded string in production
• NEVER grant default permissions on auth errors — fail to 503/redirect

Secrets & Data Exposure

• No hardcoded credentials — all secrets from OCI Vault
• Error responses must use toResponseBody() which strips internal details
• Pino logger redacts authorization, cookie, and x-api-key headers
• CSP nonce: crypto.randomUUID() per request in production
• AES-256-GCM for webhook secret encryption at rest

XSS

• SvelteKit auto-escapes template expressions — verify no {@html} with user content
• CSP headers configured via helmet plugin
• API responses set proper Content-Type headers

Approval Flow Security

• NEVER trust client-supplied approval flags
• Use server-side recordApproval() / consumeApproval() pattern
• Approval tokens must be single-use and time-limited

Oracle-Specific Security

Atomic Operations

• Rate limiting, approvals, and upserts MUST use MERGE INTO — never SELECT-then-INSERT/UPDATE (TOCTOU vulnerability)
• Fire-and-forget DB updates MUST use a separate withConnection() call

Connection Pool

• Always use withConnection(async (conn) => { ... }) — never hold connections outside callback
• Always await connection.commit() after DML operations
• Connection errors should fail-open (return safe defaults) for non-critical operations

Row Handling

• OUT_FORMAT_OBJECT returns UPPERCASE keys — use fromOracleRow() for camelCase conversion
• SYS_GUID() returns RAW(16) — ensure id columns use VARCHAR2(36)
• SYSTIMESTAMP for timestamp defaults (not CURRENT_TIMESTAMP which is session-timezone dependent)

LIKE Queries

• User-supplied search terms MUST escape %, _, and \
• Always include ESCAPE '\' clause after the LIKE pattern

JSON Columns

• CLOB columns storing JSON MUST have CHECK ({col} IS JSON) constraint
• Use JSON_VALUE() or JSON_QUERY() for extraction — not string manipulation

Migration Safety

• Use EXCEPTION WHEN OTHERS THEN IF SQLCODE != -955 THEN RAISE; END IF; for idempotent CREATE
• Blockchain tables: cannot DROP or DELETE within retention period

Bind Variables

• Always use bind parameters (:paramName) — never string interpolation
• Column/table names cannot be bind variables — use validateColumnName() / validateTableName()

Semgrep Integration

Run security scan on changed files (one at a time due to multi-file bug):

for f in {changed-files}; do
  semgrep scan --config auto --json "$f" 2>/dev/null || true
done

Report any findings in the output.

Output Format

Report findings as a markdown table:

| Severity | File:Line | Finding | Recommendation |
| -------- | --------- | ------- | -------------- |
| CRITICAL | path:42   | ...     | ...            |
| HIGH     | path:17   | ...     | ...            |

If no issues found, state "No security issues detected" with a summary of what was reviewed.

After the review table, write your fixes if the task requires code changes (not just review).

Git Protocol

• Stage ONLY the files you modified (never git add -A or git add .)
• Use flock for atomic git operations:

flock {{GIT_LOCK_PATH}} bash -c 'git add {files} && git commit -m "$(cat <<'"'"'EOF'"'"'
fix(security): description of security fix

Scope Constraint

You MUST only review and modify files listed in "Files to Review" above. If you discover vulnerabilities in other files, note them in your output but do NOT modify those files.

Orchestrate

Coordinate parallel agent teams to execute multi-task implementation plans.

What It Does

Orchestrate manages teams of specialized AI agents working on implementation plans in parallel. Instead of running 22 tasks sequentially over 4 hours, run them concurrently and finish in ~1 hour.

Key Features

• Task dependency graphs - Parses plans, respects blockers, assigns when ready
• Role-matched agents - Frontend, backend, QA, security specialists
• Heartbeat monitoring - Progressive stall detection with automatic reassignment
• Quality gates - Build/test/lint between waves, verify before transitions
• Two execution modes:
• Interactive: In-session agents with message-based coordination
• Headless: Independent claude -p processes for max parallelization

Safety & Coordination

• File overlap detection - Serializes tasks touching the same files
• Git safety - flock-based locking prevents concurrent staging conflicts
• Scope enforcement - Reverts commits that touch out-of-scope files
• Budget controls - Per-task caps, session-wide limits

Usage

/orchestrate A                    # Run Phase A interactively
/orchestrate A --headless         # Run Phase A with claude -p processes
/orchestrate docs/plans/plan.md  # Custom plan file
/orchestrate --dry-run            # Preview without spawning

How It Works

1. Parse implementation plan into task ledger 2. Spawn role-matched agents (backend-1, frontend-2, qa-1, etc.) 3. Assign tasks respecting dependencies and file overlap 4. Monitor progress with progressive stall escalation (60s ping → 120s warn → 180s reassign) 5. Run quality gates between waves (build + test + lint) 6. Verify commits and scope before marking complete

Requirements

• Claude Code CLI
• Implementation plan with task structure (see SKILL.md for format)
• For headless mode: claude -p available in PATH

Architecture

Built entirely on Claude Code's native team primitives:

• TeamCreate / TeamDelete - Team lifecycle
• TaskCreate / TaskUpdate / TaskList - Ledger operations
• SendMessage - Agent coordination (DM, broadcast, shutdown)
• Task tool - Spawning specialized agents

No external infrastructure needed.

Example

Given a plan with 22 tasks across 3 waves:

Wave 1: 6 parallel tasks (dependency updates)
Wave 2: 12 tasks (8 parallel + 4 serialized due to file overlap)
Wave 3: 4 tasks (final verification + docs)

Orchestrate spawns 5 agents, assigns work based on role matching, monitors progress, runs quality gates between waves. Result: ~1 hour wallclock vs 4 hours sequential.

Wave Execution Checklist

Reusable checklist the orchestrator reads for each wave transition. All items must pass before proceeding.

Pre-Wave

Common (Both Modes)

• [ ] All blocking tasks from previous wave are completed and verified
• [ ] Quality gate from previous wave passes (pnpm build && npx vitest run && pnpm lint)
• [ ] Git status is clean (no uncommitted changes from previous wave)
• [ ] pnpm install is current (no new dependencies pending)
• [ ] Task ledger is up to date (no stale in_progress tasks)

Headless Mode Only

• [ ] Session directory exists (/tmp/orchestrate/{session-id}/)
• [ ] No file overlap between concurrent tasks (serialized if overlapping)
• [ ] Prompts generated for all tasks in the wave (inspect with --dry-run)
• [ ] Per-task budgets within session cap
• [ ] git.lock file exists for flock-based locking

Interactive Mode Only

• [ ] All agents are idle and ready for assignment
• [ ] Team is active (TeamCreate completed, no stale agents)

During Wave

Common (Both Modes)

• [ ] No scope creep detected (agents staying within assigned files)
• [ ] Status reported to user periodically
• [ ] Each completed task has a verified commit (hash + verify command)

Headless Mode Only

• [ ] All claude -p processes spawned (PIDs recorded in session directory)
• [ ] Monitor polling running at 10s intervals
• [ ] No process exceeded timeout threshold (2x estimated duration by default)
• [ ] No budget exceeded events (total_cost_usd within per-task cap)
• [ ] Completed task outputs are valid JSON and parseable

Interactive Mode Only

• [ ] All agents acknowledged their assignments within 60s
• [ ] QA watcher is running and reporting after each file change
• [ ] Stall detection running (progressive escalation: 60s/120s/180s)
• [ ] Status reported to user every 3 minutes

Post-Wave

Common (Both Modes)

• [ ] All tasks in the wave are marked completed in the ledger
• [ ] Each task has a corresponding commit with conventional message format
• [ ] Full quality gate passes:
• pnpm build (production build succeeds)
• npx vitest run (all tests pass)
• pnpm lint (no lint errors)
• [ ] Type checks pass per workspace:
• cd packages/shared && npx tsc --noEmit
• cd apps/api && npx tsc --noEmit
• cd apps/frontend && npx svelte-check --tsconfig ./tsconfig.json --threshold error
• [ ] Security scan on changed files:
• semgrep scan --config auto <changed-files> (no high/critical findings)
• [ ] Wave summary printed with task count, duration, and issues
• [ ] Next wave's dependencies are now unblocked in the ledger

Headless Mode Only

• [ ] All output JSON files present in session directory and parseable
• [ ] Each task has exactly one new commit (scope-verified)
• [ ] No commits touch files outside task scope (revert any violations)
• [ ] Cumulative cost within session budget
• [ ] Failed tasks have been escalated through all tiers or user-resolved

Interactive Mode Only

• [ ] All agents confirmed task completion via SendMessage
• [ ] No stalled agents remaining (reassigned or shut down)
• [ ] Agent idle state is clean (ready for next wave assignment)
