What is security-advisory-compat-enforcer?

A procedure for reviewing a GitHub security advisory and updating a project’s compatibility rules with a verified safe version.

Use it to verify an advisory and patched version, then make the smallest justified update to `.github/aw/compat.json`.

It prevents unsupported version changes by requiring evidence about the affected package, advisory, and patched release.

About the project

GitHub Agentic Workflows is a GitHub CLI extension that lets developers define AI-assisted repository automation in Markdown and run it through GitHub Actions. It is intended for tasks requiring interpretation or reasoning, such as issue triage, pull-request review, CI investigation, documentation maintenance, and dependency analysis. The catalogue entries provide skills and agents for working with these workflows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00031	$0.01224
Opus 5.5	$0.00012	$0.00490
Sonnet 5.5	$0.00006	$0.00245

Security

Grade A, and why

security-advisory-compat-enforcer 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 2mo 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.

Security Advisory Compatibility Enforcer

Use this skill to translate a GitHub repository security advisory into the smallest safe update to .github/aw/compat.json.

Required inputs

Record the repository, GHSA identifier, requested enforcement policy, and any patched version supplied by the user. Treat a user-supplied version as a target to verify, not as evidence for advisory details.

Evidence retrieval

Attempt authenticated retrieval first: gh api repos/OWNER/REPO/security-advisories/GHSA-ID.
If authentication is unavailable or access fails, try the public global advisory endpoint: gh api advisories/GHSA-ID (or its equivalent REST URL).
Record the endpoint and outcome of each attempt. If both sources are inaccessible, state that explicitly. Never infer or invent the affected package, vulnerable range, severity, CVE, publication state, or patched version.
Verify the proposed patched version independently. Prefer a published repository release or tag, then package-registry metadata when applicable. Cite the exact URL or command result. Do not update compatibility policy if the target cannot be verified, unless the user explicitly directs use of a supplied target despite inaccessible advisory metadata; document that limitation without converting it into fabricated advisory evidence.

Choose the correct policy field

minimumVersion is a hard floor: activation fails for every compiler version below it. Change it only when the requested remediation is a universal minimum-version enforcement.
blockedVersions rejects listed versions exactly. Change it only when evidence or explicit instructions identify exact versions to deny and a continuous minimum floor would be inaccurate.
minRecommendedVersion only warns below the value. Change it only for an explicitly requested recommendation, never as a substitute for enforcement.
Agent rows under agent-compat-v1 select compatible agent versions; they are unrelated to compiler security enforcement unless separate evidence requires an agent compatibility change.

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.
