If this file is unreadable, BLOCK; do not infer the policy.</li>\n</ul>\n<h2>Phase 1 — Banned-primitive scan · gate: BLOCK</h2>\n<p>Scan every crypto operation in the changed code against <code>security-controls.md</code>. Apply the project's forbidden list; where it is silent, the following BLOCK unconditionally:</p>\n<ul>\n<li><strong>Broken primitives</strong> — <code>md5</code>, <code>sha1</code>/<code>sha-1</code> (including in HMAC or \"just for IDs\"), <code>des</code>, <code>3des</code>, <code>rc4</code>, and RSA keys below 2048 bits.</li>\n<li><strong>Disabled TLS verification</strong> — <code>rejectUnauthorized: false</code>, <code>verify: false</code>, or any disabling of certificate peer verification, on any connection.</li>\n<li><strong>Home-rolled crypto</strong> — a hand-built cipher, AEAD, KDF, signature scheme, or any reimplementation of a primitive in userland instead of a vetted, approved one.</li>\n<li><strong>Unapproved primitive or library</strong> — any algorithm, mode, key size, or crypto library not on the approved list in <code>security-controls.md</code>.</li>\n</ul>\n<p>Dispatch the <code>auth-crypto-reviewer</code> agent (<code>${CLAUDE_PLUGIN_ROOT}/agents/auth-crypto-reviewer.md</code>) to confirm these findings against <code>security-controls.md</code>.</p>\n<p>Gate: no banned or unapproved primitive, no disabled TLS verification, and no home-rolled crypto in the changed code.</p>\n<p><strong>On pass — record the gate:</strong> follow <code>${CLAUDE_PLUGIN_ROOT}/includes/security-gate-record.md</code> (the shared record mechanism). For this gate the relevant commit hook is <strong>H-09b</strong> (crypto/TLS). On any BLOCK, do NOT record the pass.</p>\n<p><strong>Out-of-scope finding:</strong> do not act on it and do not author an ADR (ADRs are user-attributed, via <code>/adr</code> only). Mark it inline with <code>[NEEDS-TRIAGE]</code>; never silently drop it.</p>\n<h2>Hard rules</h2>\n<ul>\n<li>MUST read <code>security-controls.md</code> before scanning — BLOCK if it cannot be read.</li>\n<li>MUST NOT use MD5, SHA1, DES, 3DES, RC4, or RSA below 2048 bits — even for non-security checksums or IDs.</li>\n<li>MUST NOT set <code>verify: false</code> or <code>rejectUnauthorized: false</code>, or otherwise disable certificate verification, on any TLS connection.</li>\n<li>MUST NOT use a home-rolled or userland-reimplemented cryptographic primitive.</li>\n<li>MUST NOT use any primitive, key size, or crypto library not on the approved list in <code>security-controls.md</code>.</li>\n<li>MUST record the <code>security-gate-passed</code> marker (via <code>hooks/security-pass.py</code>) ONLY when the gate genuinely passes — the marker is what unblocks the commit (hook H-09b), so a premature or unconditional recording defeats the gate.</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":3214,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
