Key point
Thoth inspects and tests repos and folders to turn them into reusable Custom Tools.
Details
Thoth's Custom Tool Builder turns GitHub repos, local folders, and the current Developer workspace into reusable AI tools.
The core flow is Source → Inspect → Review → Test → Enable, and you don't need to write a manifest by hand.
- It reads repo files and README to suggest useful read-only commands, and uses a deterministic fallback when no lightweight model is available.
- It checks for dangerous shell patterns, unreviewed network usage, write operations, and missing placeholders.
- It's only enabled after passing a smoke test, and the user decides whether to keep it Developer-only or bring it into normal chat.
- The tool card shows the source URL, local install path, version, command count, and availability state.
- Custom Tools are opt-in, reviewable, testable, disableable, and removable, and the original repo is never deleted.
