Tools
| Tool | Description | Behaviour |
|---|---|---|
| delta_check | Determine if a topic needs FULL, DELTA, or X-DELTA soul. | Read-only |
| faf_analyze | One-call composite — returns score, tier-ready, valid, and engine identifier. Two WASM calls, sub-millisecond total. | Read-only |
| faf_collections_search | Phase III (FRC §7b) — semantic search over a Grok Collection at the edge, KV-cached (1h TTL). Returns matched chunks (content, score, file). Requires the XAI_API_KEY secret; composes with faf_section (structural) for hybrid retrieval. Handled env-aware in the MCP handler (needs the key + KV). | Read-only |
| faf_estimate_tokens | Estimate token count for arbitrary content via the Zig WASM engine. Sub-millisecond, zero allocations. Useful for context-budget planning. | Read-only |
| faf_gate | Phase III (FRC) — pre-promotion quality gate. Scores .faf content (edge Mk4) + estimates tokens and returns a deterministic promote/hold verdict BEFORE it goes to a Grok Collection. Promote IFF score >= min_score AND tokens <= max_tokens (defaults 85/8000). Edge parity with the local gate; the hold-hint can't list empty slots at the edge. | Read-only |
| faf_get_tier | Resolve the FAF tier for a given numeric score. Returns the tier symbol (Trophy/Gold/Silver/Bronze/etc.) per the canonical tier-table. | Read-only |
| faf_memory | Phase III (FRC) — query the durable .fafm model by type/tag/priority/text. Omit filters for a structured summary. .fafm is NOT scored: this SELECTS facts (provenance preserved), never grades them. | Read-only |
| faf_orchestrate_recommendation | Takes raw content strings (`.faf`, `.fafm`, and optionally `package.json`/`CHANGELOG.md`/`README.md`) and runs deterministic drift + contradiction signals across the FAF substrate. Returns a structured `Recommendation` (recommend, severity, reason, summary) with `hints` containing the current `effective_policy` and `partial[]` for any stateful signals unavailable on the current surface. Light-lane execution (hosted) is WASM-pure with no filesystem access. Heavy-lane execution (local via bunx/rust-faf-mcp) has full FS + persisted state. Advisory only — never auto-fires. | Read-only |
| faf_score | Score .faf YAML content with the always-33 faf-kernel (WASM). Returns 0-100 (capped). The same score faf-cli and every FAF MCP give. Runs at the edge. | Read-only |
| faf_section | Phase III (FRC) — returns an EXACT, WHOLE .faf section by dotted path (e.g. "stack", "human_context"), structure preserved — the deterministic complement to blind chunking. Omit "section" to list every path. | Read-only |
| faf_validate | Validate .faf YAML content: true if mission-ready (always-33 score of 100). | Read-only |
| generate_faf_from_github | Generate a .faf file from any public GitHub repository WITHOUT cloning. Extracts 6 Ws from README, analyzes stack from languages and package.json, and generates Championship-grade AI context. Returns .faf content, quality score, and metadata. | Read-only |
| get_soul | Fetch a context soul by name. Returns structured AI context. | Read-only |
| list_souls | List all available context souls. | Read-only |
| list_tags | List all unique tags used in a soul, with counts. | Read-only |
| refresh_faf | Re-ground on .faf content — re-score with the always-33 faf-kernel (33 slots; slotignored slots drop out), report drift vs an optional baseline score, and return a stamped re-ground. The explicit re-grounding primitive for long sessions: drift → refresh → re-grounded. Built for Grok, by request. | Read-only |
| search_by_tag | Find all entries in a soul with a specific tag. | Read-only |
| search_context | Full-text search across souls. Returns matching lines only (token-efficient). | Read-only |
| tag_intel | Discover tag patterns, co-occurrence, candidates, and merge suggestions across all namepoints. Optionally suggest tags for a specific handle. | Read-only |
