Five tools with clear verb-noun naming (etch, recall, list_facts, save_soul, load_soul). All have descriptions (avg 150 chars, within 10-1024 baseline). Input schemas present with typed parameters and descriptions. Output schemas documented via return type hints. Key strengths: deterministic filtering, idempotent operations, persistence guarantees. Gaps: no enums for priority/min_priority (free-form strings invite hallucination), no pagination for list_facts (could return unbounded results), error handling in load_soul returns bare dict instead of structured error with recovery guidance.

• Convert priority and min_priority to enum constraints in schema: {"enum": ["ephemeral", "standard", "high", "critical"]}. Update descriptions to reference the enum rather than listing values inline.
• Add pagination to list_facts(): accept limit (default 20, max 100) and offset parameters. Return {"facts": [...], "total": N, "offset": M, "limit": L} to enable iteration.
• Restructure load_soul() error response: return {"status": "error", "code": "file_not_found", "message": "File not found: {path}", "recovery": "Verify FAF_SOUL_PATH environment variable or pass explicit path parameter"} instead of bare dict.
• Add optional dry_run parameter to etch() and load_soul() to preview changes without persisting. E.g. etch(..., dry_run=True) returns the fact that would be written but does not call _persist().
• Document hard cap on recall() limit in description: 'Max facts to return. Default 20; pass null for all (capped at 1000 to prevent context overflow).'
