Based on SOC occupation classification
Verify an external or AI-generated security report against the actual codebase before acting on it. Use when handed a scanner PDF, automated teardown, audit report, or bug-bounty submission — classifies every finding CONFIRMED / OVERSTATED / FALSE-POSITIVE / FABRICATED and salvages the real work items.
Creates GitHub Actions for the Marketplace. Use when scaffolding a new action, implementing composite steps, writing BATS tests, or preparing a Marketplace release.
Audit documentation against its declared hierarchy — broken links, duplicates, misplaced content, stale references, single-source-of-truth enforcement. Use for doc health reviews.
Audit README.md files against best practices for repos, accounts, or orgs. Detects missing sections, stale links, inconsistent formatting, and convention violations. Use when reviewing README quality across one or many repos.
Generate or update README.md files across three scopes — repo (with project-type detection), account (GitHub user profile), and org (organization profile). Use when creating, updating, or aligning a README to org conventions.
Audits website accessibility for WCAG 2.2 AA compliance, generating findings and code fixes. Use when reviewing accessibility, keyboard navigation, screen reader compatibility, or inclusive design.

Generates a structured session summary when triggered by the SessionEnd hook. Reuses the compacting-context template to produce consistent, synthesis-ready notes.
Add to .claude/settings.json:
{
"hooks": {
"SessionEnd": [
{
"type": "prompt",
"prompt": "/summarizing-session-end"
}
]
}
}
Gather context -- Review the conversation for what was accomplished, which files were touched, and any unresolved issues.
Generate session ID -- Use the current date and a short identifier (first 8 chars of session UUID if available, or timestamp).
Write summary -- Create ~/.claude/session-summaries/YYYY-MM-DD-<id>.md
using the output template below. Create the directory if it does not exist.
Keep it brief -- The summary must be under 50 lines. This is a summary, not a transcript.
Write to ~/.claude/session-summaries/YYYY-MM-DD-<id>.md:
# Session Summary -- YYYY-MM-DD

## Completed
<!-- Done items, one bullet per item -->
## Blockers
<!-- Blocking issues discovered (empty section if none) -->
## Findings
