Cargo CLI — Context

The context is a git-backed repository of typed markdown/MDX files that captures a workspace's GTM knowledge (company narrative, ICPs, personas, plays, proof, objections, etc.) and is read/written by both humans and agents. The cargo-ai context domain has two subdomains you'll use:

  • runtime — browse, read, write, edit, and execute against the workspace's runtime sandbox (a checked-out copy of the context repo). write/edit are pushed to the default branch; execute runs are not pushed.
  • graph — build/load the knowledge graph derived from every markdown/MDX file in the context repo.
The canonical example of a context repository is `getcargohq/cargo-workspaces`. Read its README.md to understand the domain layout and file conventions before writing new entries.
For uploading runtime-independent files (CSVs, PDFs) used in batch runs, use `cargo-workspace-management` (cargo-ai workspaceManagement file upload) instead.
For RAG file attachments to agents, use `cargo-ai` (cargo-ai content file upload).
See references/conventions.md for the full context repo structure and per-domain templates.
See references/response-shapes.md for the JSON shapes returned by each cargo-ai context command.
See references/troubleshooting.md for common errors and how to fix them.
See references/examples/authoring.md for end-to-end add / edit / delete recipes.
See references/examples/lifecycle.md for the bootstrap + refresh-from-calls playbook.
See references/examples/graph-queries.md for inspecting the knowledge graph.

Prerequisites

See `../cargo/references/prerequisites.md` for install, login (--oauth / --token), JSON output conventions, and error shapes. Verify the session with cargo-ai whoami before running any of the commands below — runtime write and runtime edit push commits to the workspace's context repo, so confirming workspace.name first is non-negotiable.

Discover the context first

Before editing anything, see what's in the context repo:

cargo-ai context runtime browse                 # list entries at the runtime sandbox root
cargo-ai context graph get                      # full knowledge graph derived from the repo's md/mdx files

Quick reference

# Runtime sandbox (checked-out copy of the context repo)
cargo-ai context runtime browse [--path <path>]
cargo-ai context runtime read --path <path> [--start-line <n>] [--end-line <n>]
cargo-ai context runtime write --path <path> --content <content> [--commit-message <message>]
cargo-ai context runtime edit --path <path> --old-string <old> --new-string <new> [--commit-message <message>]
cargo-ai context runtime execute --command <command> [--args <json>]

# Knowledge graph
cargo-ai context graph get

Runtime sandbox

The runtime sandbox is a checked-out, executable copy of the context repository. It's the surface you use to read and modify context files, and to run commands against them.

Two important behaviors to remember:

  • `write` and `edit` push to the default branch of the context repo. They are not local-only.
  • *`execute` does not push.* Changes made to files by a shell command run via execute stay in the sandbox and are discarded — use execute for builds, tests, or inspection, not for committing edits.

Uploaded content files are available read-only under `.files/`. The workspace's content file uploads (PDFs, CSVs, text — see `cargo-content`) appear in the sandbox under a .files/ directory, so a command run via execute (or read/browse) can consume them — e.g. cargo-ai context runtime execute --command ls --args '["-1",".files"]'. It sits outside the committed context tree: the sandbox's auto-commit skips it, so nothing under .files/ is ever pushed to the context repo, and you can't add or change content files from here (use cargo-ai content file … instead).

Because writes push immediately, confirm the target workspace before the first `write`/`edit`:

cargo-ai whoami   # → workspace.uuid, workspace.name

Read the workspace name back to the user. If the session is for a specific client, make sure workspace.name matches before authoring anything — there is no dry-run mode. If workspace.name is generic or ambiguous (e.g. "Main", "Test", a person's name, an internal codename), don't guess — ask the user for the company name and canonical domain (example.com) and confirm both before the first write. If you logged in without pinning a workspace, re-run cargo-ai login --oauth --workspace-uuid <uuid> (or --token <workspace-scoped-token> for non-interactive use).

Edits derived from sales-call analysis should be applied one at a time with human review, not batched. Looping an agent over many calls tends to overweight the loudest signal and miss nuance — see references/examples/lifecycle.md for the call-refresh playbook.

Browse and read

# List entries at the root of the runtime sandbox
cargo-ai context runtime browse

# List entries under a subpath (e.g. a domain folder like persona/ or play/)
cargo-ai context runtime browse --path persona

# Read a full file
cargo-ai context runtime read --path persona/vp-sales-mid-market.md

# Read only a line range (1-indexed, inclusive on both ends)
cargo-ai context runtime read --path play/inbound-trial-to-paid.md --start-line 1 --end-line 40

Write a new file

write creates (or overwrites) a file and pushes a commit to the default branch.

Begin every .md/.mdx file with a YAML frontmatter block setting title and description. Frontmatter is not validated — a file with missing, empty, or malformed frontmatter is still written and committed; it just indexes poorly in the graph (a missing title falls back to the filename, the node summary to the first paragraph). write can still fail for other reasons — repositoryNotFound, syncConflict, syncFailed, failedToWrite, or deniedPath (e.g. writing under .files/); see references/response-shapes.md.

cargo-ai context runtime write \
  --path persona/vp-sales-mid-market.md \
  --content "$(cat <<'EOF'
---
title: VP of Sales, mid-market
description: Owns pipeline, quota, and rep productivity at a 200–2,000-person company.
---

## Role
- Title: VP of Sales
- Seniority: Executive
- Function: Revenue
- Reports to: CRO or CEO

## KPIs
- New ARR, win rate, pipeline coverage, rep ramp time

## Pains
- Pipeline gaps, slow ramp, low rep activity, forecasting drift

## Motivations
- Hit the number, build a repeatable motion, get visibility

## Day-to-day
Forecast calls, deal reviews, pipeline reviews, 1:1s with frontline managers.

## Preferred channels
- medium/linkedin-outbound
- medium/exec-warm-intro

## Common objections
- objection/we-already-have-an-ai-sdr

## How we land
Lead with pipeline-coverage math, not features.
EOF
)" \
  --commit-message "Add VP of Sales mid-market persona"

Edit an existing file

edit replaces a single exact substring. --old-string must occur exactly once in the file; pass an empty --new-string to delete the match.

edit does not validate frontmatter — an edit that strips or empties title/description still applies, so keep the block intact to keep the node discoverable. edit can fail for other reasons, though: stringNotFound / stringNotUnique (the --old-string match), fileNotFound, noOp (new string equals old), syncConflict / syncFailed, failedToEdit, or deniedPath.

# Replace one specific sentence
cargo-ai context runtime edit \
  --path global/positioning.md \
  --old-string "We help RevOps automate workflows." \
  --new-string "We help RevOps run AI-native GTM motions." \
  --commit-message "Refresh positioning one-liner"

# Delete a line (pass empty --new-string)
cargo-ai context runtime edit \
  --path persona/vp-sales-mid-market.md \
  --old-string "\n- Outdated stat: 4.2x pipeline\n" \
  --new-string ""

For larger restructures, prefer write (full-file overwrite) over many sequential edit calls.

Execute a command in the sandbox

execute runs a shell command in the sandbox. Useful for inspecting structure or running checks; changes are not pushed.

# Find every file that cross-references a specific slug
cargo-ai context runtime execute \
  --command grep \
  --args '["-r","-l","persona/vp-sales-mid-market","."]'

# Count entries per domain
cargo-ai context runtime execute --command ls --args '["-1","persona"]'

# Run a one-shot script (no quotes/escaping needed inside --command beyond JSON for args)
cargo-ai context runtime execute --command pwd

--args is a JSON array of string arguments. Omit it for a no-arg command.

Context repository structure and conventions

The Cargo context repo is a typed knowledge base. The canonical example — and the source of the conventions below — is `getcargohq/cargo-workspaces`; read its README.md and _template.md files in each domain before writing new entries. For the full domain reference, see references/conventions.md.

Domains

DomainPurpose
global/Company-level context: mission, voice, positioning, narrative, pricing
icp/Ideal Customer Profile segments
persona/Buyer personas (roles inside an ICP)
jtbd/Jobs-to-be-done framings
alternative/Competitors, substitutes, status quo
client/Customer profiles, case studies, reference accounts
insight/Market insights and observations
medium/Channel playbooks (email, LinkedIn, cold call, etc.)
objection/Objections + responses + proof
play/GTM plays (signal → audience → channel → sequence → outcome)
proof/Atomic proof points (metrics, quotes, case data)
signal/Buying signals and intent triggers

File conventions

  • Filename: kebab-case.md (e.g. vp-sales-mid-market.md).
  • Frontmatter: start every .md/.mdx file with YAML frontmatter setting title and description. This is a strong convention, not enforced — a write with missing, empty, or malformed frontmatter is still created and committed; it just indexes poorly. The graph reads title (fallback: filename) and summary (fallback: the file's first paragraph); it does not read description, so add a summary: if you want to control the node summary. See Source references and graph edges.
  • Cross-references: use the domain/slug form, no `.md` extension (e.g. persona/vp-sales-mid-market). To register as a graph edge a reference must use one of the three link forms below — a bare domain/slug (or file path) in plain prose creates no edge.
  • Templates: each domain ships an _template.md. Read it (cargo-ai context runtime read --path persona/_template.md) before authoring a new entry. _template.* files are excluded from the graph — never reference them.

Source references and graph edges

The knowledge graph is built from every .md, .mdx, .yaml, and .yml file in the repo (any folder; only .git/ is excluded). Each file is a node, but edges are created only from three forms — anything else is invisible to the graph:

1. Frontmatter `references:` list (preferred for source citations — keeps prose clean):

   ---
   title: AgoraPulse expansion thesis
   description: Why AgoraPulse is ready for a multi-thread expansion play.
   references:
     - outputs/sales-notes/2026-06-05-agorapulse-build-session-1-outcomes.md
   ---

2. A Markdown link in the body — standard [label] followed immediately by (path) syntax, where the target is the file path, e.g. an anchor linking to outputs/sales-notes/2026-06-05-agorapulse-build-session-1-outcomes.md. 3. Wikilinks in the body (extension optional): [[outputs/sales-notes/2026-06-05-agorapulse-build-session-1-outcomes]].

Key constraints:

  • Never cite a source as a bare path in prose (e.g. a Source: line that just mentions outputs/sales-notes/foo.md as text) — it is not parsed and creates no edge.
  • Prefer root-relative paths (resolved from the repo root first, then relative to the citing file) so links work regardless of where the document lives.
  • Extensions are optional — the resolver auto-tries .md, .mdx, .yaml, .yml in that order. Including the extension is fine.
  • The target must exist or the edge is broken (a dead link in the graph UI). Verify with runtime browse before citing.
  • For docs with a Source/Evidence section, cite the files in frontmatter references:; use inline markdown links when the citation needs surrounding prose. Full rules: references/conventions.md.

Workflow: add a new entry

1. Confirm the target domain and copy its template:

   cargo-ai context runtime read --path persona/_template.md

2. write a new file at <domain>/<slug>.md with title + description and the body sections filled in. 3. Add cross-refs (domain/slug) where useful — keep them bidirectional when it makes sense. 4. Rebuild the knowledge graph to verify the new entry and its links:

   cargo-ai context graph get

For full per-domain templates and worked examples, see references/conventions.md and references/examples/authoring.md.

Workflow: bootstrap and refresh

To stand up a new workspace's context repo from scratch, or to refresh an existing one on a cadence, follow the two-phase lifecycle in references/examples/lifecycle.md:

1. Bootstrap (one-time): seed global/, persona/, client/, proof/, objection/, signal/ from public sources, then open a fresh agent session against the seeded repo. For the prescriptive, automatable version (domain in → files out, idempotent, with credit budget), use references/examples/bootstrap-from-domain.md. 2. Refresh (every 2–4 weeks): pull the last ~3 months of sales-call transcripts → analyze one at a time, human-in-the-loop → apply a repetition threshold before promoting any claim to context → validate by generating sequence permutations → diff the graph before/after and retire stale entries.

The repetition threshold (how many calls a claim must appear in before it lands in context) is documented in references/conventions.md.

Knowledge graph

context graph get builds (or loads from cache) the knowledge graph over every markdown/MDX file in the context repo. Use it to:

  • Audit cross-references between domains (e.g. find personas that link to plays with no proof attached).
  • Discover what already exists before writing a new entry (avoid duplicates).
  • Power downstream agents that need the typed structure of the workspace's context.
cargo-ai context graph get

The response includes the parsed frontmatter and outbound domain/slug references for each node — pipe it through jq to slice it. See references/examples/graph-queries.md for ready-to-run queries.
