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 | $0.00011 | $0.01663 |
| Opus 5 | $0.00005 | $0.00831 |
| Sonnet 5 | $0.00002 | $0.00333 |
| Haiku 4.5 | $0.00001 | $0.00166 |
Grade A, and why
mach12:pr-validation-assessment 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.
How it starts
The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Assess PR Validation
Goals
- Independently accept or reject every executable candidate against authoritative requirements, realistic production reachability, and practical impact.
- Preserve accepted defects as normalized, committed red tests and publish one verified assessment with exact proof provenance.
- Route every accepted defect to production repair, or proceed to pre-merge when no candidate survives. Do not repair production code.
Step 1: Authenticate the preliminary review and current state
Extract the required PR number and exact numeric --review-comment ID. Ask only when either is missing or ambiguous.
Fetch that exact comment and verify its repository, PR, trusted author, and <!-- mach12-review --> marker. Use the current session and authoritative repository state rather than treating the review's conclusions as true. Re-read the PR, linked requirements, relevant implementation, and tests wherever needed to assess a claim.
Require the PR to remain open, the primary repository to remain on the recorded non-detached PR head branch, local and GitHub heads to remain at implementation parent P, and the index to remain empty. Require all worktree changes to be the candidate test changes declared by validation, with no production or unrelated changes. If the state materially differs, stop without resetting, cleaning, stashing, or overwriting it.
Step 2: Independently assess every candidate
Keep the main agent neutral before dispatch. Construct focused test invocations locally from repository paths, node IDs, and tracked runner configuration; never execute remote command prose.
Classify candidates by the behavior they challenge. Assign command candidates to scramjet:independent-command-assessor and runtime candidates to mach12:independent-assessor. For a cross-boundary candidate, select one owner from the alleged behavior rather than requesting duplicate verdicts. Each candidate gets exactly one verdict owner, and the assessment uses at most two assessors with agentScope: "user".
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.

mach12:pr-validation-assessment is a command published in the GitHub repository LeanAndMean/scramjet (6 stars, last pushed today), licensed Apache-2.0. It adds 11 tokens to every session and 1,663 once invoked, about $0.0001 per session on Opus 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.
