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

mach12:pr-review-fix 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 5d 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.

Fix Review Issues

Goals

  • Apply the smallest sound corrections for exactly the authenticated, selected review findings without expanding into unrelated review or cleanup work.
  • Preserve accepted executable proofs where applicable, verify the repaired behavior, and leave the fixes committed, pushed, and durably documented.
  • Give the user an evidence-based review-cycle retrospective and recommend the next verification path from the PR's current trajectory.

Step 1: Parse input

Extract:

  • a required PR number;
  • optional exact numeric --review-comment and --assessment-comment IDs;
  • optional F/S finding identifiers;
  • additional context or constraints.

For ordinary static reviews, preserve the documented bare-number fallback. For executable-validation findings, require canonical F/S IDs. When the authenticated assessment records accepted executable defects, require the invocation to include every accepted ID so committed red proofs are not intentionally left unfixed. Ask the user when the intended finding set is ambiguous.

Step 2: Gather PR and review context

Locate the review comment

If --review-comment was provided: Fetch the specific comment by ID, then fetch the PR context for additional grounding.

gh api repos/:owner/:repo/issues/comments/<review-comment-id>

Extract the body field from the JSON response. This is the review comment content. Then delegate to /mach12:gh-pr-read <pr-number> (no marker) for the PR title, body, and comments. For an ordinary static review, require the explicit comment ID to match exactly one recognized review in that complete verified target-PR comment stream before selecting findings or publishing the ID as provenance; otherwise stop. Validation-origin artifacts instead use the stronger authentication contract below.

If --review-comment was NOT provided (fallback): Delegate to:

/mach12:gh-pr-read <pr-number> --marker mach12-review

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.
