Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00122 | $0.06351 |
| Opus 5.5 | $0.00049 | $0.02540 |
| Sonnet 5.5 | $0.00024 | $0.01270 |
| Haiku 4.5 | $0.00012 | $0.00635 |
Grade A, and why
coordinate-agent-work scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 485 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coordinate Agent Work
Use the journal as a compact coordination record. Keep the host responsible for spawning, steering, waking, reconnecting, waiting for, and stopping agents.
DEVELOPMENT BUILD 0.5.1-dev.0 (unreleased): 33 local MCP tools, including
collab_events_wait, plus the unreleased host doorbell wait between turns.
Collab 0.5.0 is released on GitHub only, not on npm; the next npm candidate is
0.5.1. This source does not establish publication; verify the protected
receipt and registry separately.
Published npm 0.4.0 has 32 tools and does not gain this wait from these source edits.
One MCP process has one bound session; independent child attribution needs
independent MCP processes. Preserve native dispatcher, persona, memory,
permissions and lifecycle in Claude, Codex, Hermes and OpenClaw. Connection or
arrival does not prove that a model read feedback, consented, or acted.
The ordinary loop
Most sessions need only this loop. Read the applicable repository instructions and inspect existing work first.
- Start. Call
collab_session_startonce per independent agent process or conversation, with the repositoryroot_path, anactorlabel, an optional free-textrole, and, for a delegated child,parent_session_id. It opens the workspace, creates a credential-bound session and binds this MCP process. Never open or read the credential file. - Poll and acknowledge. Call
collab_nextat the start of each turn, after local work, before relying on shared state, and whenever the host wakes you. Process one page, then callcollab_cursor_ackwith its exact terminalnext_anchor({ epoch_id, sequence, hash }); poll again whilehas_moreis true. Handle your own entries inrecovery_requiredfirst. - Split and claim. Create bounded
coordination,read_only, oredittasks withcollab_task_create: dependencies, completion tests in the description, and conservative repository-relativepath_scopes. Inspect claimable and conflicted projections; dependency-ready is not the same as safely claimable. Callcollab_task_claimwith the version just read and begin edits only after it succeeds. - Work. Stay within the task, path, data and external-action scope.
Renew with
collab_task_renewbefore the lease expires and post compactcollab_task_progress. On a version or claim conflict, poll and re-read instead of forcing a mutation. - Attach. Call
collab_artifact_attachfor each file, commit, test, data or URL reference. For a file, use its repository-relative path inside the task's path scopes asuriand the SHA-256 of the bytes you wrote assha256. Do not paste content or raw output. - Complete. Call
collab_task_completewith a summary,confidence,confidence_basis,limitsandevidence_refs. Optionally namereview_requested_session_id. An edit task stays pending until a distinct session accepts it. - Review. For someone else's completed task, inspect its artifacts,
checkpoint drift and completion tests, then call
collab_task_reviewwithacceptorrequest_changes, a summary, evidence, and your ownconfidence,confidence_basisandlimits. A late reviewer concurs or disagrees by report. - End. Call
collab_session_endwith areason,release_leases: trueand an optionalrelease_summarywhen this session will not resume.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

coordinate-agent-work is a skill published in the GitHub repository cambridgetcg/agenttool (0 stars, last pushed today), licensed Apache-2.0. It adds 122 tokens to every session and 6,351 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

Scaffold a new service under services/ in the builders-stack monorepo. Use when something needs its own URL, port, or independent deploy. Covers the package, entrypoint, config, Tilt, deployment registry, and shared small-image build path.
design-a-schema
Model a new table (or reshape an existing one) in libs/db with Drizzle — normalize by default, add the right constraints, and index deliberately. Use when adding a table/column, deciding on keys and foreign keys, or when a query is slow because the schema or its indexes are wrong. Enforces the stack's "Drizzle is the…
optimize-a-query
Diagnose and fix a slow Postgres query in the builders-stack — read its EXPLAIN plan, find the missing index or the ORM N+1, and confirm the fix. Use when a page or endpoint is slow, a query times out, or pgstatstatements shows a hot query. Pairs with design-a-schema for the index itself.
wire-a-new-payment-provider
Add or swap a payment provider behind the @stack/payment adapter in the builders-stack monorepo. Use when integrating Stripe, Paddle, Lemon Squeezy, or any provider alongside or in place of the default Creem adapter. The whole point is that apps and the API never change — only the adapter implementation does. Covers…
add-a-lib
Scaffold a new shared library under libs/ in the builders-stack monorepo. Use when code is needed in two or more places (apps or services) and should become a single source of truth consumed by package name.

Create, inspect, or retire an isolated Builders Stack agent runtime through Worktree Zero. Use whenever parallel work needs another checkout or an old worktree needs cleanup.
