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 | $0.00043 | $0.00564 |
| Opus 5.5 | $0.00017 | $0.00226 |
| Sonnet 5.5 | $0.00009 | $0.00113 |
| Haiku 4.5 | $0.00004 | $0.00056 |
Grade A, and why
stop-and-save 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 1mo ago.
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.
What it actually says
Stop and save
An explicit stop overrides the proactive cycle. Do not ask a next-goal question or dispatch
new work to clear sweep --check-idle; preserve those pending actions in the handoff instead.
- Stop new dispatch and record the founder's exact instruction, scope, time and source as an active hold in the canonical state. Say whether this is a session handoff or a broader hold; don't silently broaden it. A later explicit resume lifts only the matching scope.
- Read native in-flight agent status and latest available outputs. Ask existing agents to checkpoint at a safe boundary if the instruction permits; cancel when requested or needed to stop harmful effects. Do not mark them finished from an elapsed estimate. No new investigation agent while suspended unless the stop request authorizes that cleanup.
- Reconcile completed results into task records. For remaining agents, preserve ids, lane, stage, latest report, active child processes, mutation markers/backups and resource ownership. Do not infer a clean tree from a killed-agent notification. Unknown tree state is a named first resume check, not a fabricated fact.
- Write an active
handoffrecord in the database with:- Each repo/checkout's measured revision/push state, or explicitly unverified state.
- Uncommitted paths and what they were intended to become, with checkpoint/patch locations.
- Outstanding questions, exact options, source/message ids, active holds and scopes.
- Ordered resume actions, including liveness/ownership and mutation-restoration checks.
- What landed, in which environment, and what still prevents the user's goal being complete.
- Durable lessons or evidence not yet recorded elsewhere.
- Persist canonical records and their human view via
coordinator-kit:coordination-state. Create a consistent SQLite backup and commit only that bookkeeping snapshot in its owning repo; a multi-repo workspace root may not be a repo. Do not opportunistically commit or push unverified product work. - Record which session listeners end, which durable jobs/dated obligations survive, and who owns them. Do not cancel a required durable obligation or claim a session monitor survives. Confirm the saved handoff and any unresolved persistence/ownership issue concisely.
Resume uses coordinator-kit:bootstrap: read the saved handoff, reconcile actual state, honor or
explicitly lift the matching hold, then resolve the handoff record only after its actions are complete.
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.

stop-and-save is a skill published in the GitHub repository nikolamin/claude-coordinator-kit (2 stars, last pushed 29d ago), licensed MIT. It adds 43 tokens to every session and 564 once invoked, about $0.0002 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.
