Critical failures across all dimensions. The single tool 'execute_skill_action' has a minimal description (89 chars, below the 194-char baseline) that lacks WHEN/WHY context. Input schema is present but parameters lack descriptions entirely, 'patient_encounter_id' and 'audio_transcript_snippet' have no guidance on format, constraints, or dependencies. Output schema is completely undocumented; the client.py mock returns a complex object with 9 fields (subjective_summary, objective_metrics, assessment_icd10_codes, etc.) but no schema is declared to the MCP server. No error handling, no recovery guidance, no validation rules. The tool name 'execute_skill_action' is generic and violates verb_noun clarity, 'generate_clinical_soap_note' would be far more specific. No security considerations (HIPAA data handling, credential injection, audit logging) despite clinical/sensitive context. Tool composition is monolithic, should split SOAP generation, ICD-10 coding, and EHR sync into separate tools for agent composability.

• Rename tool to 'generate_clinical_soap_note' to follow verb_noun convention and clearly signal intent to LLMs.
• Add parameter descriptions: 'patient_encounter_id' (format: ENC_* string, required, unique identifier), 'audio_transcript_snippet' (format: plaintext, max 5000 chars, clinical conversation transcript).
• Document output schema with all 9 fields: encounter_id (string), subjective_summary (string), objective_metrics (object with blood_pressure, heart_rate_bpm, ecg_sinus_rhythm), assessment_icd10_codes (array of strings), plan_interventions (array of strings), ehr_epic_cerner_fhir_json_synced (boolean), physician_documentation_time_saved_pct (number 0-100).
• Add error handling: 'If audio_transcript_snippet is empty or malformed, return error with guidance to provide valid clinical conversation. If HIPAA validation fails, return specific redaction errors. If EHR sync fails, return partial SOAP with sync_status=failed and retry guidance.'
• Split into separate tools: generate_soap_note (subjective+assessment), extract_objective_metrics (vital signs), assign_icd10_codes (coding), sync_to_ehr (EHR integration). Each tool should accept encounter_id and return chainable IDs for downstream calls.
