# CAST Audit Skill ## Overview The `/cast-audit` skill automates the 4-way codebase audit that was run manually on 2026-04-16, surfacing accumulating drift and regressions before they compound. It dispatches 4 parallel researchers (bugs/dead code, security, performance, test coverage), collates findings, and writes a report to `~/.claude/reports/cast-audit-YYYY-MM-DD.md`. **Does NOT auto-fix.** This skill surfaces findings only. Remediation happens via follow-up agent dispatch (`debugger`, `security`, `test-writer`). ## Usage ### Manual invocation ```bash /cast-audit ``` Runs full audit and writes report to `~/.claude/reports/cast-audit-YYYY-MM-DD.md`. ### Options - `/cast-audit --since 2026-03-01` — Only flag regressions (increases, new findings) since the date. Compares against the most recent prior audit before that date. - `/cast-audit --section security` — Run one section only (security, bugs, performance, or coverage). Output still goes to the full report. - `/cast-audit --no-collate` — Run 4 parallel researchers but do NOT collate into a single report. Useful for debugging individual sections. ### Scheduled execution **Design intention: first Monday of each month, 08:00 local time.** Scheduling via RemoteTrigger or cron requires a helper script that is not yet shipped (see "Scheduling" below). Manual invocation only until then. The scheduled run: 1. Dispatches the 4 researchers in parallel 2. Writes section reports to `~/.claude/reports/cast-audit-YYYY-MM-D...
