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 | $0.00081 | $0.01633 |
| Opus 5.5 | $0.00032 | $0.00653 |
| Sonnet 5.5 | $0.00016 | $0.00327 |
| Haiku 4.5 | $0.00008 | $0.00163 |
Grade A, and why
record-evidence 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 22d 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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Record acceptance-criterion evidence
Evidence is the bridge between "I claim it works" and "it is demonstrably done". Record one true, specific row per acceptance criterion, plus the smallest-change note, then stop. You do not submit, push or open a PR: the runner runs the gates, records the delivery and submits for review; it pushes and opens a PR only when the operator has enabled that.
Steps (delivery agent)
- Commit first. Evidence describes committed work:
git status --porcelainmust be empty apart from runner-excluded files, andgit log -1 --onelineshows yourdeliver #N: …commit. Note the short SHA for your summaries. - List the ACs.
get_ticket→acceptance_criteria: eachid, its text, and whether it carries acheck_command. - For each AC, find the proof that exercises THAT AC's own behaviour. Name the test
file and test name, and say what it asserts. A green suite is not evidence for an AC
unless a test in it would fail if the AC were not met. If no such test exists, write it
now (and re-run) — do not paper over the gap; reviewers reject an AC without one.
For an AC with a
check_command, run that exact command yourself first: the runner runs it after you stop, a failure sends the delivery back, and only the runner's own check result can satisfy that AC — your row for it is supporting evidence only. - Record one row per AC with
record_ac_evidence:ticket_id,ac_id,evidence_type, and asummaryunder 5,000 characters. Pick the type that matches the proof:test_output(command + pass summary + the named test),coverage_report,static_analysis(lint/typecheck),diff_summary,commit,screenshot,log,ci_run(a CI run you actually observed),manual_note(a verified observation no command could capture). Noclaim_tokenis needed; the runner injects it. Recording with anac_idmarks that AC satisfied (an AC with acheck_commandis still not done until the runner's own check passes), so only record what is true. A good summary: "pnpm test src/lock.test.ts→ 14 passed.two concurrent saves both persistfires 2 writers via Promise.all and asserts both records exist (AC2). abc123f". - Record the smallest-change note — one
manual_noterow with NOac_id, whose summary startssmallest-change check:and names the files you changed by file name, what you cut or refused, and why this size is the floor. The runner scans evidence for the phrase "smallest-change" (or "smallest change"), uses the MOST RECENT such row (its ownneeds_human_reviewflags excluded), and flags one that names none of the changed files (by file name or a stem of four or more characters) as boilerplate. Record it once, after your final edit. This is the same line theself-reviewskill asks for: if you already recorded it in this run, do not repeat it. On a rework or resume, record a fresh note for the diff as it now stands — the newest note is the one the runner reads (on a resume the call is refused; see below). See theminimalismskill. - Record the digest delta with the
prepare-digest-deltaskill. - Stop. Once every AC has a row, the note and the delta are recorded, you are done.
Do not call
submit_ticket_for_review, push, open a PR, or keep polishing.
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.

record-evidence is a skill published in the GitHub repository tmj-90/gaffer (2 stars, last pushed 23d ago), licensed Apache-2.0. It adds 81 tokens to every session and 1,633 once invoked, about $0.0003 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.
