ralph-mcp demonstrates solid definition quality with comprehensive parameter schemas, mostly clear descriptions, and good naming discipline. All 15 tools have explicit input schemas with typed parameters and descriptions. Tool names follow verb_noun conventions (ralph_start, ralph_status, ralph_update, etc.). However, several tools have overly complex schemas with nested objects and conditional dependencies that lack explicit documentation. Output schemas are not documented. Error handling guidance is minimal. The server shows strong foundational quality but lacks the refinement and LLM optimization of A-grade tools.

• Document output schema for every tool. Create a table or structured section in the README showing: tool name, input schema, output schema, example response for each.
• Decompose ralph_update into separate tools: update_story_status (simple params), verify_story_hard_gates (gate-specific), verify_story_scope (scope-specific). Each tool with one responsibility is easier for LLM to reason about.
• Add actionable error guidance to descriptions: 'If PRD file not found, ensure prdPath points to a valid markdown file in the project (e.g., tasks/prd-001.md). Call ralph_doctor to verify project structure.'
• Expand terse descriptions (ralph_get, ralph_claim_ready, etc.) to 100-150 chars. Include one sentence on typical usage: 'Call this after ralph_status shows a PRD is in 'ready' state to claim ownership and begin work.'
• Document enum values inline in descriptions. E.g., onConflict: 'Strategy for merge conflicts, auto_theirs (prefer incoming branch), auto_ours (prefer main), notify (require user), agent (require agent decision).'
• Add idempotency guarantees: 'Calling ralph_start twice with the same prdPath is safe; only one execution is created.' or 'Calling ralph_merge twice with the same branch is unsafe; second call will fail with branch-already-merged error.'
• Document state machine in PRD execution status: 'Valid transitions: pending→ready→starting→running→(completed|failed|interrupted)→merged|stopped. Call ralph_get to inspect current state before state-changing operations.'
• Add resource chaining IDs: If ralph_start returns an execution_id, ensure ralph_status, ralph_get, ralph_update all accept and document execution_id as primary key alongside branch name. Include execution_id in every response.
