This server exhibits significant quality gaps across naming, descriptions, schemas, and error handling. While tool names follow verb conventions (get_*, add), three of four tools expose sensitive configuration (API key, server endpoint) as parameters rather than using server-side injection. Descriptions vary widely in quality, some are adequate (get_global_stats at 98 chars) while others are trivial (get_api_key at 11 chars, below the 20-char minimum). Parameter schemas are present but inconsistent: get_global_stats has proper typed parameters with descriptions, while get_ccc_server and get_api_key have empty input objects. The add tool is out of scope (demonstration tool, not domain-relevant). Output schemas are not documented, callers must infer return types from tool names. Error handling is absent; no validation, no recovery guidance, no timeout handling for the requests.get() call. The server returns raw API responses without truncation or pagination, risking context window exhaustion. Critical security issue: get_api_key tool exposes credentials as a callable parameter, violating secret-injection pattern.

• Remove get_ccc_server and get_api_key tools entirely. Inject server_endpoint and api_key server-side via environment variables (already done in __init__). The agent does not need to retrieve these; they are internal implementation details.
• Expand get_ccc_server and get_api_key descriptions to 50 - 150 characters explaining their purpose, when to call them, and what they return. Currently 11 chars each.
• Add explicit output schema documentation for all tools. E.g., 'Returns: dict with keys [global_stats, summary_by_program, summary_by_organization, ...]' or return a Pydantic model to auto-generate schemas.
• Add timeout (e.g., timeout=30) to requests.get() in get_global_stats. Wrap in try/except to catch and provide actionable errors: 'API timeout: {server_endpoint} took >30s. Try again or check service status.'
• Implement pagination in get_global_stats: add limit (default 20, max 100) and offset parameters. Return total_count and next_offset. Truncate large result sets to prevent context explosion.
• Add input validation to get_global_stats: verify from_date and to_date match YYYY-MM-DD format before calling API. Return 'Invalid date format: {from_date}. Expected YYYY-MM-DD.' for malformed input.
• Remove the add tool or move it to a separate 'utilities' server. It is not part of the CommCare Connect domain.
• Add per-parameter type constraints in get_global_stats schema: program_id (positive integer), organization_id (positive integer), from_date and to_date (regex: ^\d{4}-\d{2}-\d{2}$).
