Vendored Docs

Rule: vendored docs first

Before searching the internet for any Rust crate or Python package API, always check vendored docs first:

ls docs/vendored/rust/{NAME}-*.md docs/vendored/python/{NAME}-*.md 2>/dev/null

If a guide exists, read it — it contains curated patterns, project-specific gotchas, and a full API reference with complete signatures and docs.

Only reach for the internet if no vendored guide exists or it doesn't cover the specific API you need.

Generating docs

The scripts are bundled with this plugin — no need to copy them into your project.

Rust crates

# Full pipeline: resolve version from Cargo.lock, generate rustdoc JSON, convert
python3 ${CLAUDE_SKILL_DIR}/scripts/rustdoc-json-to-md.py {CRATE_NAME}

# Explicit version
python3 ${CLAUDE_SKILL_DIR}/scripts/rustdoc-json-to-md.py {CRATE_NAME} {VERSION}

# Reuse existing JSON (faster re-runs)
python3 ${CLAUDE_SKILL_DIR}/scripts/rustdoc-json-to-md.py {CRATE_NAME} --skip-build

# Convert existing JSON file directly
python3 ${CLAUDE_SKILL_DIR}/scripts/rustdoc-json-to-md.py --json target/doc/{CRATE}.json

# Compact index or stdout
python3 ${CLAUDE_SKILL_DIR}/scripts/rustdoc-json-to-md.py {CRATE} --only-index --stdout

Requires nightly toolchain: rustup toolchain install nightly (won't change your default).

Python packages

# Must use a Python env where the package is installed
python3 ${CLAUDE_SKILL_DIR}/scripts/pydoc-to-md.py {PACKAGE}

# Explicit version
python3 ${CLAUDE_SKILL_DIR}/scripts/pydoc-to-md.py {PACKAGE} {VERSION}

# Control depth and scope
python3 ${CLAUDE_SKILL_DIR}/scripts/pydoc-to-md.py {PACKAGE} --depth 1
python3 ${CLAUDE_SKILL_DIR}/scripts/pydoc-to-md.py {PACKAGE} --include numpy --include random

# Compact index or stdout
python3 ${CLAUDE_SKILL_DIR}/scripts/pydoc-to-md.py {PACKAGE} --only-index --stdout

Both scripts use -o PATH to override the output path. Defaults: docs/vendored/rust/{name}-{version}.md (Rust) and docs/vendored/python/{name}-{version}.md (Python).

Adding curated content

The scripts generate the full API reference. To add curated content (patterns, gotchas), edit the file and add sections above the # Full API Reference separator. Re-running the script preserves the curated section.

Curated section structure

## Common Patterns
[5-10 working code snippets from tests/codebase, 5-15 lines each]

## Gotchas
- **Problem:** ...
- **Why:** ...
- **Fix:** ...

## Config Options
| Option | Type | Default | Description |

## Compatibility Notes
[versions, known incompatibilities]

# Full API Reference
{machine-generated — do not edit below this line}

Where to find patterns and gotchas

Rust:

• Your codebase: use {CRATE_NAME} in crates/ or src/
• Crate source: ~/.cargo/registry/src/*/{CRATE}-{VERSION}/tests/
• Comments: NOTE, HACK, WARNING, FIXME, TODO, #[deprecated]

Python:

• Your codebase: import {PACKAGE} or from {PACKAGE} import
• Package tests: {site-packages}/{PACKAGE}/tests/
• Docstring warnings and deprecation notices

Quality rules

1. Code snippets must come from working code — never guessed
2. The API reference section is machine-generated — re-run the script to update it
3. If unsure about a signature, read the source — do not guess
