Critical gaps across all dimensions. Tool definitions lack proper JSON Schema input validation, most parameters are documented in descriptions but not formally typed in schemas. Descriptions are present but often generic (10-50 chars), failing to explain WHEN to use tools or what they return. No output schemas documented. Error handling is absent, tools will fail silently or with raw shell errors. Security concerns: publish_artifact and clone_with_hash accept file paths as strings with no validation, risking path traversal. No tool annotations (readOnlyHint, destructiveHint) despite clear WRITE/READ_ONLY risk classifications. Composition is poor: publish_artifact and artifact_server are tightly coupled; ios_safari_debug tools should be unified. Parameter descriptions lack constraints (e.g., port ranges, path formats). No pagination or result limits documented.

• Add formal JSON Schema input definitions for all tools. Currently, parameter types and constraints are documented in descriptions but not machine-parseable. Use 'type', 'enum', 'minimum', 'maximum', 'pattern' fields.
• Expand tool descriptions to 80-150 characters. Include: (1) what the tool does, (2) when to use it vs similar tools, (3) what it returns. E.g., 'Serve agent artifacts on LAN/VPN with a dashboard. Call this after publish_artifact to enable browsing. Returns HTTP URL and artifact list.'
• Document output schemas for all tools. Specify returned fields, types, and whether results are paginated. E.g., iosdbg_tabs should document: returns array of {tab_id, url, title, connected: bool}.
• Add input validation and path sanitization. Normalize paths, reject '..' and symlinks, validate port ranges (1-65535), and validate enum values. Return actionable errors: 'Invalid port 99999, must be 1-65535.'
• Add tool annotations: mark publish_artifact, clone_with_hash, ios_safari_debug_install, iosdbg_eval, install_artifact_service with destructiveHint=true; mark artifact_server, browser_tools, iosdbg_tabs, iosdbg_logs with readOnlyHint=true.
