firstmate is an agent distribution that lets one coding agent coordinate a crew of autonomous agents working in separate git worktrees. It is for running parallel fixes, investigations, plans, and audits while receiving completed pull requests, merges, or reports through one supervising agent. The catalogue entries provide skills, hooks, instructions, and settings for operating this workflow.

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 | $0.00020 | $0.01124 |
| Opus 5.5 | $0.00008 | $0.00450 |
| Sonnet 5.5 | $0.00004 | $0.00225 |
| Haiku 4.5 | $0.00002 | $0.00112 |
Grade A, and why
agent-skill-trigger-index 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 2d 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.

Agent-only reference skills
These skills are not captain-invocable; load them only at their precise triggers.
operational-home-layout- load when locating, interpreting, or changing Firstmate home, config, data, state, project, or generated runtime paths.session-start-recovery- load when the session-start digest reports unfinished checks, actionable diagnostics, recovery inputs, or output requiring interpretation.bootstrap-diagnostics- load whenever the session-start digest's bootstrap or network-checks section prints an actionable diagnostic line (MISSING:,MISSING_MANUAL:,OUTDATED:,PRESENTATION_UNAVAILABLE:,BACKEND_INVALID:,NEEDS_GH_AUTH,TANGLE:,STARTUP_MEMORY_BUDGET:,CREW_DISPATCH: invalid,FLEET_SYNC:,NETWORK_CHECKS:,HOME_SUMMARY:,BACKLOG_RECONCILE:,SECONDMATE_SYNC:,SECONDMATE_LIVENESS:,SECONDMATE_HANDOFF:,NUDGE_SECONDMATES:, orFMX:), or whenBOOTSTRAP_INFO:says an interrupted backlog cleanup may have left an endpoint or local copy; silence and otherBOOTSTRAP_INFO:facts need no load.diagnostic-reasoning- load before scoping a reported bug and before acting on a diagnostic report.ask-user-authority- load before deciding any ask-user finding.validation-supervision- load when a ship starts or already has an active no-mistakes validation run, including a mid-run requirement change or finding, and before deciding or answering any ask-user finding.ship-landing- load when a ship reports a PR or ready branch, when deciding or monitoring landing, and before task cleanup.scout-completion- load when a scout reports completion, presents a visual artifact for iteration, or is being considered for promotion to implementation.quota-array-dispatch- load before choosing among a matched crew-dispatch profile array from current quota-axi default TOON.harness-adapters- load before spawning or recovering a crewmate or secondmate, handling a trust dialog, sending a harness-specific skill invocation, interrupting or exiting an agent, resuming an exited agent, or verifying a new harness adapter.firstmate-orca- load before switching to Orca, spawning or supervising Orca-backed work, smoke-testing Orca backend behavior, debugging Orca task state, or reconciling Orca-backed task metadata.project-management- load before adding, creating, removing, or initializing a project. Cloning or registering a project is add intake and uses the same trigger.stuck-crewmate-recovery- load when the session-start digest reports an ordinary direct report's endpoint dead or its metadata has no window, after a stale wake, looping pane, repeated confusion, an answered-by-brief question, an unresponsive crewmate, or a failed steer, and whenever a live worker reports its no-mistakes pipeline dead, unreachable, or timed out.secondmate-provisioning- load before creating, seeding, validating, launching, handing backlog to, recovering, pushing inherited local material into, or retiring a secondmate home, and before editingdata/secondmates.md.captain-hold-lifecycle- load before treating an investigation or visual review as complete, before ending a visual review that exposed a captain decision, when recording or routing the captain's answer, and on anyRECORD DIVERGENCEline from the wake drain.away-quiet-supervision- load whenever /afk or /quiet is invoked, an away or quiet record exists, or a marked away-supervisor message arrives.process-event-sources- load before arming a long-polling source, before registering a deterministic condition->action watch (do X as soon as Y is true), on anyprocevent <adapter> <source-id> <sequence>check wake, and on anyprocess-event source strandedorprocess-event source failed to startcheck wake. Never run a registered source's blocking command yourself in a conversational turn.fmx-respond- load on anx-mention <request_id>check:wake to handle the mention, on anx-mode-error ...check:wake to report the Relay configuration blocker, on apublic-followup ...check:wake or a startup-surfaced public commitment, and on any milestone or terminal wake for a Relay-linked task before posting its completion follow-up; relevant only when Relay is on.firstmate-codexapp- load before coordinating a visible Codex Desktop thread, evaluating a Codex App backend request, or reconciling Codex Desktop host-tool smoke evidence for Firstmate work.firstmate-coding-guidelines- load before changing firstmate's shared, tracked material, as defined by section 1's list, whether editing directly or briefing a crewmate for a firstmate-repo task.
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.

agent-skill-trigger-index is a skill published in the GitHub repository kunchenguid/firstmate (8,295 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 1,124 once invoked, about $0.0001 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 2026-09-28.
