llmlb: Skill for Claude Code

.claude/skills/gwt-project-index/SKILL.md

gwt-project-index is a skill for Claude Code from akiojin/llmlb. It costs 29 tokens per session (375 once invoked), scanned A, original, MIT.

A project-file search tool that builds a vector index of source files and compares a natural-language query with that index. A vector index is a searchable representation of meaning, so related files can be found without exact keyword matches.

In plain words
What is it for?
Use it to find relevant source files, discover similar implementations, or understand how a project is organized.
Why use it?
It reduces the time spent guessing where code lives in an unfamiliar project. It can surface files for feature work, bug investigation, and architecture exploration.

This is akiojin/llmlb's own configuration. It tells Claude Code how to work on llmlb itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llmlb configures →

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 A, and why

gwt-project-index 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 8d 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

Project Structure Index

gwt maintains a vector search index of all project files using ChromaDB embeddings.

File search command

Run in terminal to find files related to a feature or concept:

~/.gwt/runtime/chroma-venv/bin/python3 ~/.gwt/runtime/chroma_index_runner.py \
  --action search \
  --db-path "$GWT_PROJECT_ROOT/.gwt/index" \
  --query "your search query" \
  --n-results 10

On Windows, use ~/.gwt/runtime/chroma-venv/Scripts/python.exe as the Python executable.

File search output format

JSON object with ranked results:

{"ok": true, "results": [
  {"path": "src/git/issue.rs", "description": "GitHub Issue commands", "distance": 0.12},
  {"path": "src/lib/components/IssuePanel.svelte", "description": "Issue list panel", "distance": 0.25}
]}

When to use

  • Task start: search for files related to the assigned feature
  • Bug investigation: find files that might relate to the bug
  • Feature addition: locate existing similar implementations
  • Architecture understanding: discover how components are organized

Environment

  • GWT_PROJECT_ROOT: absolute path to the project root (set by gwt at pane launch)

Notes

  • File index is auto-generated when the project is opened in gwt
  • Uses semantic similarity (not just keyword matching)
  • Lower distance values indicate higher relevance
  • For Issue search, use gwt-issue-search instead
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.
