Server has 8 tools with mixed quality. Most tools lack descriptions entirely (get_key_info, list_algorithms, list_keys, rotate_key, sign_message have no visible descriptions). Only 2 tools (check_keypair, delete_key) have descriptions. Input schemas are partially visible but incomplete, many tools lack documented parameter descriptions. No output schemas documented. Error handling not evident in source. Tool naming follows verb_noun pattern (good), but lack of descriptions and parameter documentation severely limits LLM usability. This is a typical community server with structural gaps.

• Add descriptions to all 6 undocumented tools. Each should explain WHAT it does, WHEN to use it, and what it returns. Target 50-200 characters per pattern:tool-description.
• Document input schemas for all tools: add parameter descriptions explaining format, constraints, and allowed values. E.g., generate_key should document algorithm enum (ed25519, ecdsa-secp256k1, etc.) and key_id format.
• Document output schemas for all tools. E.g., list_keys should return [{key_id, algorithm, created_at, ...}]; generate_key should return {key_id, public_key, algorithm}.
• Add error handling guidance to tool descriptions. E.g., 'If key not found, call list_keys() to see available keys. If algorithm unsupported, call list_algorithms() first.'
• Change delete_key secureWipe default to false or require explicit confirmation. Destructive operations should never silently default to irreversible behavior per pattern:confirmation-request.
