Project Search

gwt maintains a vector search index of project implementation files using ChromaDB embeddings (model: intfloat/multilingual-e5-base). The index is stored at ~/.gwt/index/<repo-hash>/worktrees/<worktree-hash>/files/ (with a sibling files-docs/ collection for documentation). The gwt TUI keeps a per-Worktree filesystem watcher running so changes flow into the index automatically. When invoked outside the TUI, the runner auto-builds the index on the first call.

Environment

When the gwt TUI launches an agent pane, the following env vars are exported automatically:

• GWT_PROJECT_ROOT — absolute path of the active worktree
• GWT_REPO_HASH — SHA256[:16] of the normalized origin URL
• GWT_WORKTREE_HASH — SHA256[:16] of the canonicalized worktree absolute path

File search command (code)

~/.gwt/runtime/chroma-venv/bin/python3 ~/.gwt/runtime/chroma_index_runner.py \
  --action search-files \
  --repo-hash "$GWT_REPO_HASH" \
  --worktree-hash "$GWT_WORKTREE_HASH" \
  --project-root "$GWT_PROJECT_ROOT" \
  --query "your search query" \
  --n-results 10

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

Project docs search

~/.gwt/runtime/chroma-venv/bin/python3 ~/.gwt/runtime/chroma_index_runner.py \
  --action search-files-docs \
  --repo-hash "$GWT_REPO_HASH" \
  --worktree-hash "$GWT_WORKTREE_HASH" \
  --project-root "$GWT_PROJECT_ROOT" \
  --query "your search query" \
  --n-results 10

When to use

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

Notes

• The TUI watcher (2 s debounce, 100-file batch) keeps the index live; non-TUI sessions get an mtime+size diff per call
• The runner auto-builds the index when missing (use --no-auto-build to suppress)
• search-files is implementation-focused and excludes embedded skill assets, local/archived SPEC trees, local task logs, and snapshot files
• Project docs are indexed separately and can be searched with search-files-docs
• Uses semantic similarity (not just keyword matching)
• Lower distance values indicate higher relevance
• Canonical standalone skill name: gwt-project-search
• Internal runner actions remain search-files / index-files
• For SPEC search, use gwt-spec-search instead
• For Issue search, use gwt-issue-search instead
