Mixed quality across 7 tools. All tools have descriptions (10 - 100 chars) and visible schemas with type definitions. However, descriptions are terse and lack LLM-optimized guidance (e.g., 'when to use', 'prerequisites', 'prerequisites'). Parameter descriptions exist but are minimal. Output schemas are not documented. Error handling is present in code (e.g., check_command safety checks, bounded_integer validation) but error messages are not specified in tool definitions. Naming is clear and verb-forward (Read, Write, Edit, Bash, Glob, Grep, NotebookEdit). Risk annotations are present (READ_ONLY, WRITE, IRREVERSIBLE) which is good practice but not captured in the schema. No confirmation patterns for destructive operations (Write, Edit, Bash, NotebookEdit). The tool set shows solid engineering discipline (workspace bounds, timeout caps, stream limits) but lacks agent-facing optimization (idempotency hints, chaining fields, error recovery guidance).

• Expand tool descriptions to 80 - 150 chars. Include: (1) what the tool does, (2) when to use it instead of related tools, (3) key constraints (e.g., 'max 25KB output per stream'), (4) idempotency for Read/Glob/Grep (safe to retry), (5) destruction risk for Write/Edit/Bash/NotebookEdit. Example: 'Read a bounded UTF-8 file. Returns up to 25KB of text; request offset/limit to fetch specific ranges. Safe to retry. Use before editing to preview file content.' (160 chars).
• Document output schemas for all tools. E.g., Read returns {status: 'success'|'error', content?: string, truncated?: boolean, total_lines?: number}. Bash returns {exit_code: number, stdout: string, stderr: string, timed_out: boolean}. This enables agents to extract fields for downstream tool chaining.
• Add error recovery guidance in tool descriptions. E.g., Bash: 'If the command times out, reduce the scope (e.g., check one file instead of the whole tree). If validation fails, the command violated safety checks, use a simpler command. Call Glob to find safe targets first.' This prompts agents to self-correct.
• Implement a confirmation tool or MRTR (Multi-Round-Trip Request) pattern for irreversible operations. Before executing Write/Edit/Bash/NotebookEdit, return {status: 'confirm_required', action: '...', message: 'This will delete X lines. Confirm?'} and wait for user or agent approval. This prevents catastrophic mistakes.
• Expose workspace bounds and timeout caps in tool descriptions. E.g., Read: 'Reads files within the workspace root. Cannot access parent directories. Offset and limit are bounded to prevent DoS.' Bash: 'Timeout defaults to 60s, capped at 600s. Output is truncated at 25KB stdout + 25KB stderr.' This sets realistic expectations.
