Documentation Audit

Systematically verify claims in documentation against the actual codebase using a two-pass approach.

Overview

Core principle: Low recall is worse than false positives—missed claims stay invisible.

Two-pass process:

1. Pass 1: Extract and verify claims directly from docs
2. Pass 2A: Expand patterns from false claims to find similar issues
3. Pass 2B: Compare codebase inventory vs documented items (gap detection)

Quick Start

1. Identify target docs (user-facing only, skip plans/, audits/)
2. Note current git commit for report header
3. Run Pass 1 extraction using parallel agents (one per doc)
4. Analyze false claims for patterns
5. Run Pass 2 expansion searches
6. Generate docs/audits/AUDIT_REPORT_YYYY-MM-DD.md

Claim Types

Verification confidence:

• Tier 1 (auto): file_ref, config_default, env_var, cli_command
• Tier 2 (semi-auto): symbol_ref, version_req
• Tier 3 (human review): behavior, constraint

Pass 2 Pattern Expansion

After Pass 1, analyze false claims and search for similar patterns:

Dead script found: diagnose_track_selection.py
  → Search: all script references → Found 8 more dead scripts

Wrong interval: "every 10 seconds"
  → Search: "every \d+ (seconds?|minutes?)" → Found 3 more

Wrong service name: ai-radio-break-gen.service
  → Search: service/timer names → Found naming inconsistencies

Common patterns to always check:

• Dead scripts: scripts/*.py references
• Timer intervals: every \d+ (seconds?|minutes?)
• Service names: ai-radio-*.service, *.timer
• Config vars: RADIO_* environment variables
• CLI flags: --flag patterns in bash blocks

Output Format

Generate docs/audits/AUDIT_REPORT_YYYY-MM-DD.md:
