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:
- Pass 1: Extract and verify claims directly from docs
- Pass 2A: Expand patterns from false claims to find similar issues
- Pass 2B: Compare codebase inventory vs documented items (gap detection)
Quick Start
- Identify target docs (user-facing only, skip
plans/,audits/) - Note current git commit for report header
- Run Pass 1 extraction using parallel agents (one per doc)
- Analyze false claims for patterns
- Run Pass 2 expansion searches
- Generate
docs/audits/AUDIT_REPORT_YYYY-MM-DD.md
Claim Types
| Type | Example | Verification |
|---|---|---|
file_ref | scripts/foo.py | File exists? |
config_default | "defaults to 'AI Radio'" | Check schema/code |
env_var | STATION_NAME | In .env.example + code? |
cli_command | --normalize flag | Script supports it? |
behavior | "runs every 2 minutes" | Check timers/code |
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/*.pyreferences - Timer intervals:
every \d+ (seconds?|minutes?) - Service names:
ai-radio-*.service,*.timer - Config vars:
RADIO_*environment variables - CLI flags:
--flagpatterns in bash blocks
