A documentation-quality checker for the doctree-mcp wiki. It looks for pages that are disconnected, unusually short, missing information at the top, or linked incorrectly.

Use it to find orphaned pages, stub pages, missing title or category fields, and broken links, then decide what documentation needs improvement.

It reveals documentation gaps that can make a wiki hard to navigate or unreliable for readers and tools.

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	$0.00027	$0.00351
Opus 5.5	$0.00011	$0.00140
Sonnet 5.5	$0.00005	$0.00070
Haiku 4.5	$0.00003	$0.00035

Security

Grade A, and why

doc-lint 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 2mo ago.

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.

What it actually says

Audit Wiki Health

Perform a health check on the doctree-mcp wiki using the available tools.

Workflow

Step 1: Find orphaned pages

list_documents()

Look for documents where the links to: field is absent or empty — these have no inbound cross-references from other docs.

Step 2: Find stubs

In the list_documents results, identify documents with very low word counts (under ~100 words). Call get_tree on each to confirm they are sparse rather than just compact.

Step 3: Check frontmatter

For each flagged doc, call get_node_content(doc_id, [root_node_id]). Check whether frontmatter includes: title, description, tags, type, category.

Step 4: Report and fix

For each issue found, report to the user:

Orphaned pages: Suggest adding a cross-reference link from a related doc. Stubs: Suggest either expanding the content or merging it into a related doc. Missing frontmatter: Suggest the missing fields based on the content you read.

Ask the user whether to fix each issue now, or skip.

Tips

Run bunx doctree-mcp lint in the terminal for a quick machine-readable summary
Use find_similar if you want to check whether a stub should be merged into another doc
Cross-references are markdown links — adding [Auth Guide](../auth/guide.md) to a doc removes its orphan status

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.
