Babel CLI exposes 22 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, mostly terse), and input schemas are present with type definitions. However, descriptions lack LLM-optimization guidance (e.g., 'when to use', 'prerequisites', 'side effects'). Output schemas are undocumented, LLMs cannot predict return structures. Error handling is absent; no recovery guidance or categorization. Parameter descriptions are minimal (1-3 words). No enums for constrained inputs (e.g., 'format' in git_context, 'operation' in lsp). Composition is reasonable (single-responsibility tools), but chaining metadata is sparse. Security concerns: run_command and mcp_request are high-risk with minimal guardrails. Overall, this is a functional but immature tool set suitable for internal use, not production agent deployment.

• Document output schemas for all tools. Include field names, types, and descriptions. E.g., read_file should return {content: string, encoding: string, size_bytes: number}.
• Expand tool descriptions to 50-200 chars. Add 'when to use', prerequisites, and side effects. E.g., 'Read a file from the workspace. Use read_range() for large files to avoid context bloat. Returns raw content; use semantic_search() to find files first.'
• Add enums for constrained parameters. E.g., git_context.format: enum [summary, diff, status, log]; lsp.operation: enum [goToDefinition, findReferences, hover, documentSymbol, workspaceSymbol, goToImplementation, prepareCallHierarchy, incomingCalls, outgoingCalls].
• Implement error handling with recovery guidance. E.g., run_command should return {exit_code, stdout, stderr, error_type: 'timeout|permission_denied|not_found', recovery_hint: 'Try with sudo or check PATH'}.
• Add permission gates and audit logging for destructive tools (write_file, str_replace, apply_patch, run_command). Log caller, parameters, timestamp, and outcome for compliance.
