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 | $0.00053 | $0.01316 |
| Opus 5 | $0.00026 | $0.00658 |
| Sonnet 5 | $0.00011 | $0.00263 |
| Haiku 4.5 | $0.00005 | $0.00132 |
Grade A, and why
jackin-refresh-pr 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 6d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
jackin-refresh-pr
Reconcile an open PR's title and body against the current diff, so the body describes what the branch actually ships now — not what it shipped when it was opened. Run when the body has drifted: more commits landed, scope grew or shifted, the title still reads docs: but the PR now ships a feature.
Shares cargo xtask pr body with jackin-create-pr — the binary owns the Verify-locally block selection; the agent owns the prose. This is the deliberate, on-demand version of the reconciliation jackin-merge-pr runs at its step 5.
When to use
- Operator asks to refresh / update the PR body or title ("the body is out of date", "refresh the PR").
- Body has become actively misleading for a reviewer landing on it right now.
When NOT to use
- Opening a new PR →
jackin-create-pr. - At merge-readiness →
jackin-merge-prstep 5 reconciles as the final gate; don't double-refresh. - After every iteration commit — refresh is operator-triggered, not commit-triggered (
.github/AGENTS.mdPR-body refresh policy). Auto-refreshing churns the body and wastes attention.
Arguments
PR— PR number (defaults to the current branch's PR).
Process
- Resolve the PR.
gh pr view <PR> --json number,title,body,headRefName,baseRefName. Hold the current title and body. - Gather the fresh shape.
git fetch origin <baseRefName>, thencargo xtask pr body --base origin/<baseRefName> > /tmp/pr-body.fresh.md. Read the change digest on stderr (the rust/docs/capsule/schema categories + file list) — that is what the change is now. Read the fresh skeleton on stdout — its set of###blocks under## Verify locallyis the selection the current diff requires. - Reconcile the Verify-locally blocks. Diff the fresh skeleton's block set against the live body's:
- In the fresh selection but missing from the body → add it (structure from the template, filled for this PR).
- In the body but dropped by the fresh selection → remove it.
- In both → keep the operator's fill verbatim. The Checkout block carries the real PR number; Rust tests carry the scoped filter; User smoke carries PR-specific steps. Never overwrite a kept block with the placeholder.
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.
