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 | $0.00151 | $0.04115 |
| Opus 5 | $0.00076 | $0.02057 |
| Sonnet 5 | $0.00030 | $0.00823 |
| Haiku 4.5 | $0.00015 | $0.00411 |
Grade A, and why
bearings 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
bearings
Generate a complete current snapshot from the fleet's current state, so the captain can resume in one read after a break, a night, or a context reset.
Plain /bearings returns only the concise four-section chat digest.
Only /bearings file writes the dated markdown report artifact and then returns the concise four-section chat digest linked to that report.
Only /bearings lavish builds the interactive fleet board beside that digest, through bin/fm-bearings-board.sh (its header owns every board mechanic and the fm-bearings-board.v1 payload contract).
A digest/build invocation is operationally read-only apart from the cooldown-limited reconcile instruction and its state/<id>.reconcile-nudged record, plus the explicit per-mode artifacts: the dated report in file mode, and in lavish mode the board file plus the answer binding and source registration that bin/fm-bearings-board.sh build records through their own owners.
During that invocation it never tears down a task, merges a PR, dispatches new work, steers a worker except through that reconcile hook, answers a decision, cleans up work, or mutates backlog or task state beyond the reconcile record.
Board answers are acted on later under the normal authority rules; this skill's board-wake section explicitly owns the guarded routing at that time.
Invocation modes
- Plain
/bearingsgathers a fresh bounded snapshot and renders the four-section chat digest without creating, deleting, reading, or replacingdata/status-report-<YYYY-MM-DD>.md. /bearings filegathers a fresh bounded snapshot, replaces today'sdata/status-report-<YYYY-MM-DD>.mdfrom scratch, and renders the four-section chat digest with a link or path to that report./bearings lavishgathers a fresh bounded snapshot, rebuilds and arms the interactive fleet board (the "Lavish board mode" section below), and renders the four-section chat digest with the board's URL inside it.- Treat
fileandlavishonly as explicit invocation options in the slash command. - Do not treat natural-language requests such as "write a report", "save this", "persist it", "make a file", or "make a board" as file or lavish mode unless the invocation explicitly includes the standalone option.
- When the captain asks to include PRs, pass the snapshot command's live-PR opt-in.
/bearings include PRsremains chat-only and makes the live-PR opt-in./bearings file include PRsand/bearings lavish include PRscompose the same way.
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.

bearings is a skill published in the GitHub repository kunchenguid/firstmate (4,420 stars, last pushed yesterday), licensed MIT. It adds 151 tokens to every session and 4,115 once invoked, about $0.0008 per session on Opus 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 2026-08-30.
