indexion-documentation

indexion-documentation is a skill for Claude Code from trkbt10/indexion-skills. It costs 39 tokens per session (1,203 once invoked), scanned C, original, Apache-2.0.

A documentation analysis tool for checking how much of a codebase is documented and whether the code and its documentation have drifted apart. A public API is the code meant for other code or users to call.

In plain words
What is it for?
Measuring documentation coverage by package and declaration type, finding undocumented public items, detecting code-to-documentation drift, and producing reports or GitHub issues.
Why use it?
It shows what documentation is missing, stale, or unevenly covered instead of relying on manual inspection. It can also turn findings into a prioritized documentation plan.

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.

Security

Grade C, and why

indexion-documentation scanned grade C with 1 finding 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.

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.

indexion documentation — Documentation Analysis

Assess documentation state and detect drift. This skill covers the evaluation side of the documentation lifecycle: what exists, what's missing, what's stale. For building READMEs, see indexion-readme.

"What needs documentation?"

# Quick coverage overview — how much of the public API is documented?
indexion plan documentation --style=coverage .

Reports:

  • Overall coverage percentage (documented / total pub items)
  • Per-package breakdown with README presence
  • Functions vs types coverage split

Output example:

Overall Coverage: 81% (2285/2806)
Functions: 89%, Types: 75%

For a detailed plan with prioritized action items:

# Full plan with priorities and package inventory
indexion plan documentation .

# As a GitHub Issue for tracking
indexion plan documentation --format=github-issue .

# JSON for scripting
indexion plan documentation --format=json .

For a quick per-file listing of undocumented items:

# Which pub declarations lack doc comments?
indexion grep --undocumented src/

How detection works: Uses KGF tokenization to find visibility keywords (pub, public, export) paired with declaration keywords (fn, struct, enum, type, trait). Associates /// doc comments with declarations. Language-agnostic — works for any KGF-supported language.

Caveat: ///| marker-only comments count as "documented" even without descriptive text. Check doc_preview in the output for quality, not just coverage.

"Are my docs up to date?"

Detect drift between implementation code and documentation.

# Full reconcile report in markdown
indexion plan reconcile --format=md .

This compares code symbols against documentation and reports:

  • Vocabulary divergence: source code terms missing from co-located docs
  • Stale docs: code changed after docs were last updated
  • Missing docs: code modules with no documentation coverage

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.
