jackin-refresh-pr

jackin-refresh-pr is a skill for Claude Code, Codex from jackin-project/jackin-dev. It costs 53 tokens per session (1,316 once invoked), scanned A, original, Apache-2.0.

A skill for updating an open pull request so its title and description match the branch’s current code changes.

In plain words
What is it for?
Use it to refresh an existing pull request’s title, prose, and local verification instructions. It is not for opening a new pull request or performing the final merge-readiness update.
Why use it?
Pull request descriptions can become misleading after more commits are added or the scope changes. It refreshes the description when an operator asks, without doing so after every commit.

Token cost

What it costs to keep this loaded

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.

Security

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-pr step 5 reconciles as the final gate; don't double-refresh.
  • After every iteration commit — refresh is operator-triggered, not commit-triggered (.github/AGENTS.md PR-body refresh policy). Auto-refreshing churns the body and wastes attention.

Arguments

  • PR — PR number (defaults to the current branch's PR).

Process

  1. Resolve the PR. gh pr view <PR> --json number,title,body,headRefName,baseRefName. Hold the current title and body.
  2. Gather the fresh shape. git fetch origin <baseRefName>, then cargo 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 locally is the selection the current diff requires.
  3. 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.

Changes

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.
