The server defines 9 tools with reasonable naming (verb-prefixed: saihm_remember, saihm_recall, saihm_forget, saihm_share, etc.), all with descriptions and explicit input schemas. However, several critical gaps reduce the overall score: (1) descriptions are concise but lack depth on error cases, recovery steps, and when to use each tool vs. alternatives; (2) output schemas are not documented, we see input parameter types but no description of what each tool returns or its structure; (3) parameter descriptions are present but sometimes minimal (e.g., 'The cell ID to erase' for saihm_forget lacks any note on irreversibility or consequences); (4) no guidance on parameter relationships or idempotency; (5) error handling descriptions are absent, LLMs cannot infer what to do if a recall fails, a share is revoked mid-operation, or governance voting times out. The tools follow a clear noun_verb pattern (saihm_<action>) and leverage a single domain (SAIHM memory), which aids composition. Strengths: explicit input schemas with typed parameters; consistent naming; security-conscious design (client-side sealing mentioned in comments but not in tool descriptions); tool descriptions exist for all 9 tools. Weaknesses: output schemas undocumented; error handling unpublished; no guidance on which tool to call first or dependencies between tools.

• Document return types and response schemas for all 9 tools. E.g., 'Returns { success: bool, cellId: string, timestamp: ISO8601, message?: string }' for saihm_remember. Include what happens on partial failure (e.g., if saihm_recall is called for 5 cells and 2 are missing).
• Add error handling guidance to each tool description. E.g., 'If saihm_recall fails with 'cell not found', try saihm_status to verify the identity is active and has access. If the cell was shared but revoked, call saihm_share again with the recipient.'
• Expand parameter descriptions with constraints and examples. E.g., saihm_remember's 'cellId' should state 'Must be a non-empty string, 1-256 characters, alphanumeric + underscore/hyphen.' saihm_governance_propose's 'details' should list valid proposal types ('rotate_key', 'update_metadata', etc.).
• Document tool dependencies and calling order. Add to server.instructions or each tool description: 'Agents should call saihm_status first to confirm the identity is active, then saihm_recall to load memories, then execute actions.' Specify which tool returns what reference IDs needed by downstream tools.
• Clarify governance workflow: describe proposal lifecycle, voting thresholds, quorum requirements, and how votes are tallied. E.g., 'A proposal requires 50% approval from active identity holders. Voting ends after 24 hours or 100% participation.'
• Declare permission scopes for each tool. E.g., saihm_forget requires 'write:memory', saihm_governance_vote requires 'vote:governance'. This enables least-privilege agent configuration and clear audit trails.
