What is doc-reviewer?

A documentation review tool for checking project documents such as READMEs and files in docs/. It examines accuracy, completeness, clarity, structure, links, commands, and whether references are still current.

Use it for full, focused, or staleness reviews of one document or a collection of documents. It can verify file references, test commands, and links.

It helps catch documentation that no longer matches the codebase or leads users through broken steps. This makes project instructions more dependable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.03253
Opus 5	$0.00028	$0.01626
Sonnet 5	$0.00011	$0.00651
Haiku 4.5	$0.00006	$0.00325

Security

Grade A, and why

doc-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (tests/test_doc_reviewer_gate7_integration.py, tests/test_doc_reviewer_per_dimension_timing.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Documentation Reviewer

Purpose

Review project documentation for accuracy with codebase, completeness of coverage, clarity for users, consistency with conventions, staleness of references, and logical structure. Uses a 6-dimension rubric optimized for user success.

Use this skill when

Review documentation (README, CONTRIBUTING, docs/*.md)
Conduct FULL / FOCUSED / STALENESS documentation review
Verify documentation is current with the codebase
Check for broken links or outdated references

Inputs

Required:

review_date: YYYY-MM-DD
review_mode: FULL | FOCUSED | STALENESS
model: Model slug (e.g., claude-sonnet-45)

Optional:

target_files: List of file paths (defaults to project docs if not specified)
review_scope: single | collection (default: single)
focus_area: Required if review_mode is FOCUSED. If FOCUSED mode and focus_area missing: STOP, report error Missing required input: focus_area for FOCUSED mode
output_root: Root directory for output files (default: reviews/). Subdirectories doc-reviews/ or summaries/ appended automatically. Supports relative paths including ../.
overwrite: true | false (default: false) - If true, overwrite existing review file. If false, use sequential numbering (-01, -02, etc.)
timing_enabled: true | false (default: false — doc-reviewer retains its current opt-in default; the per-dimension timing pipeline added in v2.2.0 is wired up but not yet universally enabled. When set to true, Step 4a checkpoint pairs and Gate 7 apply.)
execution_mode: parallel (default, 6 sub-agents) | sequential - Execution strategy for dimension evaluation

Default Target Files

When target_files not specified, reviews:

./README.md - Project overview and setup
./CONTRIBUTING.md - Contribution guidelines
./docs/*.md - All documentation files in docs/ folder

Outputs

Single scope (per-file): {output_root}/doc-reviews/<doc-name>-<model>-<YYYY-MM-DD>.md

What ships with it

35 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
