Chromium Documentation SKILL

A Claude Code skill that provides intelligent search across Chromium's official documentation.

Setup

Build the documentation index:

bash

cd agents/skills/chromium-docs
python scripts/chromium_docs.py --build-index

The SKILL will automatically activate for Chromium-related queries.

Usage

Ask questions about Chromium development and the SKILL will search official documentation:

"How does Chromium's multi-process architecture work?"
"Content layer API documentation"
"How to write Chromium tests?"
"GPU rendering best practices"

To use this skill, symlink or copy SKILL.md to your agent's skills directory (e.g., .claude/skills/chromium-docs/).

Configuration

The data/configs/search_config.json file controls search behavior and was manually created based on Chromium's codebase structure. Key sections:

Section	Purpose	When to Update
`indexing.scan_patterns`	Glob patterns for docs to index	New doc locations added
`indexing.excluded_patterns`	Directories to skip	New generated/vendor dirs
`categories`	Doc classification (api, testing, etc.)	Major component changes
`search.boost_factors`	Relevance weighting	Search quality tuning

Updating the Config

Edit search_config.json directly
Rebuild index: python scripts/chromium_docs.py --build-index
Test searches to verify results

Categories and patterns should match actual directory structures in the Chromium repo.

Testing

Run Unit Tests

bash

cd agents/skills/chromium-docs/scripts
python -m pytest chromium_docs_test.py -v
# Or without pytest:
python chromium_docs_test.py

Manual Verification

After making changes, verify the skill works correctly:

bash

# 1. Build the index
python scripts/chromium_docs.py --build-index

# 2. Test search functionality
python scripts/chromium_docs.py "mojo ipc"
python scripts/chromium_docs.py "browser test"
python scripts/chromium_docs.py "gpu architecture"

# 3. Verify results include relevant docs with reasonable scores

Expected behavior:

Search results should include relevant document titles and paths
Results are ranked by relevance (title matches rank higher)
Categories should match the document content
