* Session Summary
** Date: 2025-11-22
** Focus Area: Implementing a web search capability for Claude Code and Antigravity agents.

* Accomplishments
- [X] Explored the `skills` repository structure and documentation (`AGENTS.md`, `RFC-AI-AGENT-EXTENSIBILITY-PATTERNS.md`).
- [X] Confirmed that Antigravity is not natively supported but can utilize skills via their underlying Bash scripts.
- [X] Implemented the `web-search` skill based on requirements from `claude-code-web-search.md`.
  - Created `skills/web-search/SKILL.md` documentation.
  - Created `skills/web-search/scripts/search.sh` helper script.
- [X] Verified the skill functionality by successfully querying "current time in Tokyo" and "latest stable version of python".

* Key Decisions
** Decision 1: Implement as a Standard Skill
- Context: We needed a way to search the web using Claude Code's subprocess capability.
- Rationale: Following the existing pattern in the `skills` repo ensures compatibility and reusability.
- Impact: The skill is available for Claude Code (via native loading) and Antigravity (via manual script execution).

** Decision 2: Use `claude -p` with `--allowedTools`
- Context: Standard `webfetch` only gets static HTML.
- Rationale: The `--allowedTools "web_search,WebSearch,mcp__*"` flag explicitly grants the subprocess permission to use the search tool, which is otherwise restricted.
- Impact: Enables dynamic web searching including "Product Investigation" and "Nix Package Discovery" workflows.

* Technical Details

** Code Changes
- New files created:
  - `skills/web-search/SKILL.md`: Defines the skill interface and usage.
  - `skills/web-search/scripts/search.sh`: Bash wrapper for the `claude` CLI.

** Commands Used
```bash
# The core command implemented in the script
claude -p "Search the web for '$QUERY'. Provide a summary of findings." \
  --allowedTools "web_search,WebSearch,mcp__*"

# Verification
./skills/web-search/scripts/search.sh "current time in Tokyo"
```

* Process and Workflow

** What Worked Well
- The `skills` repo structure is clear and easy to extend.
- Using `claude -p` as a bridge to web search is a powerful pattern.

** What Was Challenging
- Antigravity does not automatically discover these skills, requiring manual script invocation or future tooling (symlinks/workflows).

* Context for Future Work

** Open Questions
- How best to expose these skills to Antigravity globally?
  - Option 1: Global Binaries (symlinks to `~/.local/bin`).
  - Option 2: Antigravity Workflows (`.agent/workflows/`).
  - We are leaning towards a hybrid approach (Global Binaries + Local Workflow stubs).

** Next Steps
- Decide on the global exposure strategy.
- Commit the new skill to the repository.
