Three tools with complete schemas and descriptions, but significant gaps in error handling, output documentation, and parameter clarity. Tool names follow verb_noun convention (rlm_start, rlm_execute, rlm_end). Descriptions are present (100-200 chars) and explain purpose. Input schemas are well-formed with types, descriptions, and constraints (min/max for integers, enums for detail_level). However, output schemas are not documented, LLMs cannot predict response structure. Error handling is minimal: no recovery guidance, no categorization of retryable vs fatal errors. Parameter descriptions lack actionable constraints (e.g., 'path' should specify 'absolute path required' more clearly). No tool annotations (readOnlyHint, destructiveHint). Session-based design (rlm_start → rlm_execute → rlm_end) introduces statefulness that complicates agent reasoning.

• Document output schemas for rlm_start and rlm_execute. Example: rlm_start returns {session_id: string, metadata: {total_files: int, total_lines: int, file_types: dict}, limits: {max_llm_calls: int, max_execute_calls: int, execution_timeout_seconds: int}, available_functions: [string], strategy?: string, example?: string}. rlm_execute returns {output: string, execution_time_ms: int, variables_count: int, new_variables?: [string]}.
• Add recovery guidance to error responses. Instead of 'Directory not found: /path', return 'Directory not found: /path. Verify the path exists. Call glob_files() or tree() to explore available directories.' Categorize errors: retryable (timeout, rate limit) vs user-fixable (invalid path, permission denied) vs fatal (sandbox crash).
• Add tool annotations to schema. Mark rlm_start, rlm_execute, rlm_end with readOnlyHint: true in their tool definitions so agents can programmatically detect safety.
• Clarify parameter constraints in descriptions. For 'path': 'Absolute path to the directory to explore. Must exist and be readable. Relative paths are resolved to absolute. Symlinks are followed.' For 'code': 'Python code to execute. Must be valid Python 3.10+ syntax. Execution is sandboxed and cannot access the filesystem outside the session path.'
• Consider stateless redesign: instead of session_id, accept path + query in every rlm_execute call, or use resource URIs (e.g., 'rlm://session-abc/execute') to encode session context without requiring explicit state tracking.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
