vouch-propose-from-pr

vouch-propose-from-pr is a skill for Claude Code, Codex from vouchdev/vouch. It costs 17 tokens per session (260 once invoked), scanned A, original, MIT.

A command that turns a merged GitHub pull request into proposed statements about what the code now guarantees. A pull request is a requested code change that has been accepted and merged into the project.

In plain words
What is it for?
Use it to read a merged pull request and propose up to five cited knowledge-base claims about its meaningful behaviour changes.
Why use it?
It preserves the reasoning and behavioural decisions from a code change, which can otherwise be lost in the merge history. The statements remain pending for human review.

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

vouch-propose-from-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 4d 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.

What it actually says

/vouch-propose-from-pr

A PR is a decision: someone proposed a change, the team accepted it. The "why" gets compressed into the merge message and forgotten. This command preserves the why as cited claims in the KB.

Steps:

  1. Parse $ARGUMENTS as a PR URL or <owner>/<repo>#<num>; default to the most-recently-merged PR you authored.
  2. Fetch the PR title, body, and the merged-commit SHA via gh.
  3. Register the merge commit as a kb_register_source so subsequent claims can cite it.
  4. Read the diff. For each behavioural change (not formatting / renaming), draft one kb_propose_claim whose text summarises the new invariant the code now upholds, citing the source from step 3.
  5. Propose at most five claims per PR. If a PR is that big, suggest the contributor split it next time.

Do not auto-approve. The KB's review gate is intentional; this command only fills the queue.

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.
