## Findings

- **info** Install scripts ([install-script](https://anlyon.dev/methodology#install-script))

```untrusted-server-text
The package.json has a "postinstall" script, which npm runs on install.

scripts.postinstall: "node scripts/postinstall.js"
```

- **warn** Annotations that disagree with the tool in `generate_faf_from_github` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "generate_faf_from_github" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "generate_faf_from_github" says "generate": a word for a change.
```


## Changes things (11)

Creates or changes something that can be changed back. Claude Code: ask.

### `delta_check`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Determine if a topic needs FULL, DELTA, or X-DELTA soul.
```

### `faf_business_card`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Print a business card for an agent from its own name, description, colour and picture. Returns the agent's .fafa (FAF Agent file) and a link that opens its card. Nothing is stored: the .fafa travels in the link. The card says "self-declared" because nothing is checked against a repo.
```

### `faf_estimate_tokens`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Estimate token count for arbitrary content via the Zig WASM engine. Sub-millisecond, zero allocations. Useful for context-budget planning.
```

### `faf_gate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `faf_memory`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `faf_orchestrate_recommendation`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `faf_score`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `faf_section`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `generate_faf_from_github`

- The name "generate_faf_from_github" says "generate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `refresh_faf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `tag_intel`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Discover tag patterns, co-occurrence, candidates, and merge suggestions across all namepoints. Optionally suggest tags for a specific handle.
```

## Only reads (9)

Looks things up and changes nothing. Claude Code: allow.

### `faf_analyze`

- The name "faf_analyze" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One-call composite — returns score, tier-ready, valid, and engine identifier. Two WASM calls, sub-millisecond total.
```

### `faf_collections_search`

- The name "faf_collections_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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).
```

### `faf_get_tier`

- The name "faf_get_tier" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Resolve the FAF tier for a given numeric score. Returns the tier symbol (Trophy/Gold/Silver/Bronze/etc.) per the canonical tier-table.
```

### `faf_validate`

- The name "faf_validate" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate .faf YAML content: true if mission-ready (always-33 score of 100).
```

### `get_soul`

- The name "get_soul" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a context soul by name. Returns structured AI context.
```

### `list_souls`

- The name "list_souls" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List all available context souls.
```

### `list_tags`

- The name "list_tags" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List all unique tags used in a soul, with counts.
```

### `search_by_tag`

- The name "search_by_tag" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find all entries in a soul with a specific tag.
```

### `search_context`

- The name "search_context" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full-text search across souls. Returns matching lines only (token-efficient).
```
