Lume exposes 8 tools with critical definition gaps. Tool names lack action verbs (bash, memory.promoteglobal, automation_set, write, edit, multiedit, notebookedit). Descriptions are present but minimal (10-50 chars), providing no context on WHEN to use each tool or what happens on failure. Input schemas visible for only 3 tools (bash, write, edit, multiedit, notebookedit show file_path/edits/notebook_path); memory and automation_set tools have no visible schema. No output schemas documented. No parameter descriptions beyond the field name. No error handling guidance. No idempotency or retry semantics declared despite destructive operations (bash, write, edit). Tool names like 'memory.promoteglobal' and 'memory.rejectglobalcandidate' use dot notation and lack clarity on what 'promote' and 'reject' mean in context. No enum constraints on parameters. Descriptions do not explain prerequisites, side effects, or recovery paths.

• Rename tools with clear action verbs: 'execute_bash_command', 'write_file', 'edit_file', 'edit_multiple_files', 'edit_notebook', 'promote_memory_to_global', 'reject_global_memory_candidate', 'set_automation_task'.
• Expand all descriptions to 50-200 chars. Include: what the tool does, when to use it (vs similar tools), what it returns, and any prerequisites. Example: 'Execute a bash command with safety guardrails. Use for file operations, system queries, or scripting. Returns stdout, stderr, and exit code. Supports timeout and resource limits.'
• Document output schemas for all tools. Specify return fields, types, and whether results are paginated. Example for bash: {stdout: string, stderr: string, exit_code: number, duration_ms: number}.
• Add parameter descriptions for all inputs. For file_path: 'Absolute or relative path to the file. Must be within workspace boundary. Supports glob patterns for multiedit.'
• Implement error handling with recovery guidance. For bash: 'Command failed with exit code 127. Ensure the command exists and is in PATH. Try 'which <command>' to verify.' For write/edit: 'File path outside workspace boundary. Allowed root: /workspace. Got: /etc/passwd.'
