Single tool 'execute_skill_action' has a generic, action-agnostic name that violates verb_noun convention. Description (95 chars) is vague and does not explain WHAT the skill does, WHEN to use it, or what it returns. Input schema is minimal (single string param with no format/length constraints). No output schema documented, LLM cannot predict response structure. No error handling guidance. Tool appears to be a pass-through stub with no real implementation visible. Composition is poor: a single catch-all tool that claims to handle 'Autonomous Code Synthesis' but provides no specificity.

• Rename tool to a specific verb_noun pattern. Examples: 'analyze_pull_request_risk', 'score_code_change_blast_radius', 'assess_database_migration_impact'. This enables LLM to infer intent from the name.
• Expand description to 150-250 chars explaining: (1) What the tool analyzes (PR diffs, code changes, database schemas), (2) When to use it (before merging risky PRs), (3) What it returns (risk score, flagged components, mitigations). Example: 'Analyze a pull request diff to identify semantic risks and blast radius. Returns risk score (0-1), risk level (LOW/MEDIUM/HIGH), flagged components, and suggested mitigations. Use before merging database or API changes.'
• Document output schema explicitly in the tool definition. Include fields: risk_assessment_id (string), overall_risk_score (number 0-1), risk_level (enum: LOW_RISK, MEDIUM_RISK, HIGH_RISK_BREAKING_CHANGE), flagged_blast_radius_components (array of strings), suggested_mitigations (array of strings), pr_risk_report_markdown_url (string).
• Add parameter constraints to 'query_payload'. Specify expected format (unified diff format, JSON with 'diff' and 'metadata' fields, or free-form text). Add length limits (e.g., max 100KB). Add description: 'Unified diff output from git diff or PR platform. Include file paths, line changes, and context. Max 100KB.'
• Implement real error handling. Return structured errors with actionable guidance: 'Invalid diff format: expected unified diff. Example: diff --git a/file.py b/file.py\n-old_line\n+new_line'. Categorize errors as retryable (malformed input) vs fatal (service unavailable).
