Four tools with clear verb-noun naming (feedbacks_status, feedbacks_poll, feedbacks_sessions, feedbacks_session). Descriptions are present and moderately detailed (100-200 chars), explaining WHAT each tool does and WHEN to use it. However, critical gaps: (1) feedbacks_poll and feedbacks_session lack explicit output schema documentation, the code builds complex nested structures (timeline segments with screenshots, transcripts, speech spans) but the tool definitions do not document the return type; (2) parameter descriptions are minimal, 'since' and 'session_id' in feedbacks_poll lack format/range guidance; (3) no error handling guidance in descriptions (e.g., what if the HTTP server is unreachable, or session_id is invalid?); (4) no mention of idempotency or side effects. The server instructions are comprehensive, but tool-level definitions are incomplete. Baseline: 194 chars avg description (these are ~120-150), 100% of A+ tools document return types (this server does not).

• Document output schemas for all tools. For feedbacks_poll, specify: {active: bool, sessionId: string, startTime: number, latestSeqNum: number, events: [{type: string, offsetTime: number, ...}], timeline: [{type: 'speech'|'context', start: number, end: number, screenshots: [...], transcripts: [...]}]}. For feedbacks_session, document the full timeline structure with field types.
• Add format/range constraints to parameters. E.g., 'since: integer, 0 or greater, typically the latestSeqNum from the previous poll response' and 'session_id: string, optional, UUID or session directory name'.
• Add error handling guidance to descriptions. E.g., 'If the feedbacks server is unreachable, returns {active: false, error: "..."}. If session_id is invalid, returns {error: "Session not found"}. Retry with feedbacks_status() to check server health.'
• Declare idempotency explicitly in descriptions. E.g., 'This is a read-only tool, safe to call repeatedly without side effects.'
• Add pagination/limit guidance to feedbacks_sessions. E.g., 'Returns up to 50 most recent sessions. If more exist, implement client-side filtering or add a limit parameter.'
• Include chaining IDs in responses. If feedbacks_session returns session metadata, include session_id so downstream tools can reference it without re-lookup.
