Inkling provides 6 tools with reasonable naming (verb_noun pattern) and descriptions, but critical gaps undermine quality. Tool descriptions are present but often vague or procedural rather than LLM-optimized. Input schemas are visible and mostly typed, but parameter descriptions are sparse or missing. Output schemas are not documented. Error handling is absent, no guidance on recovery, retryable vs fatal errors, or actionable error messages. The ideas_setup tool has a confusing description that reads like a prompt rather than a clear tool contract. No pagination support despite list operations. Security concerns: no mention of permission gates or audit trails for write operations (ideas_claim_next, ideas_complete, capture_idea).

• Rewrite ideas_setup description: 'Configure inkling mode (queue vs retain), daily budget, and model capture settings. Call with no arguments to receive setup questions; call with answers object to apply configuration.' This is declarative and LLM-actionable.
• Document output schemas for all tools. E.g., ideas_list should return {ideas: [{id, text, project, source, ts}], total_count, next_cursor}. ideas_status should return {pending_count, mode, daily_cap_usd, spent_today_usd}.
• Add descriptions to all parameters. E.g., 'answers' in ideas_setup: 'Configuration object with mode, daily_cap_usd, and model_capture fields. Omit to receive setup questions instead.'
• Add error handling guidance: 'If no pending ideas exist, returns {error: "inbox_empty", message: "No pending ideas. Call capture_idea to add one."}' for ideas_claim_next.
• Document permission requirements and audit logging: 'Requires write:ideas permission. All calls logged with user_id, timestamp, and outcome for compliance.'
