Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| read_web_sourceA | Reads a public HTTP(S) page as text and returns its URL, retrieval time, SHA-256 fingerprint, and a bounded excerpt. Private network addresses are blocked. |
| read_github_sourceB | Reads one file from a GitHub repository using the GitHub contents API. GITHUB_TOKEN is optional for public repositories and required for private ones. |
| read_local_sourceA | Reads one UTF-8 text file located inside SOURCE_ROOTS and returns canonical provenance. Symbolic-link escapes are rejected. |
| search_local_sourcesA | Searches filenames and bounded UTF-8 files inside SOURCE_ROOTS. Build outputs, dependency folders, and Git metadata are skipped. |
| read_image_sourceA | Returns a PNG, JPEG, GIF, or WebP image from an allowed local path or public URL, together with verifiable provenance. The connected AI must itself support image content to interpret it. |
| list_source_policyA | Lists the configured read-only roots, host allowlist, source limits, and provenance guarantees. |
| search_fantasy_catalogA | Searches canonical fantasy entity cards stored in the managed catalog. Results include facts, relations, and provenance and never modify the catalog. |
