Autonomous AI coding agent with MCP server capabilities for file operations, terminal execution, web search, project scanning, and git operations
Celebrimbot has 15 tools with explicit schemas and descriptions, but quality is inconsistent. Tool names lack action verbs (read_psi, delete_file, write_file are acceptable; but web_search, fetch_page, list_files, grep_files, find_file, file_stats, git_* are generic). Descriptions are present but brief (10-50 chars typical), lacking context on WHEN to use each tool or what happens on failure. Parameters have types and descriptions, but no enums for constrained inputs (e.g., git commands). Output schemas are not documented, callers don't know what structure to expect. Error handling is minimal: tools return success/output tuples but no recovery guidance. Destructive tools (delete_file, run_terminal) lack confirmation or dry-run patterns. No tool annotations (readOnlyHint, destructiveHint) visible in schema generation.
Delete a file
Fetch and read a URL
Show line count and size of a file
Find files by name fragment
Show per-line authorship of a file
Show current branch name
Show uncommitted changes, optionally for a specific file
Show recent commit history
No output schemas documented. Tools return ToolResult(success, output, metadata) but callers don't know the structure of 'output' field, is it JSON, plaintext, or structured? This forces LLMs to parse unstructured text.
Destructive tools (delete_file, run_terminal) lack confirmation or dry-run patterns. Agents can accidentally delete files or execute harmful commands without a safety gate.
Tool names lack action verbs or are generic. 'read_psi' is cryptic (LOTR reference, not descriptive). 'run_terminal' is vague, does it execute, compile, or test? Prefer 'execute_shell_command'. Generic names like 'list_files', 'grep_files', 'find_file' conflate similar operations.

Show working tree status
Regex search across project files
List project files, optionally filtered by path and extension
Read the content of a file
Execute a shell command
Search the web via DuckDuckGo
Write raw content to a file (creates or overwrites). Use this when you already have the final content.
Descriptions are too brief (10-50 chars) and lack context. 'Show working tree status' doesn't explain WHEN to call git_status vs git_log vs git_diff. No guidance on prerequisites or dependencies between tools.
No error recovery guidance. Tools return ToolResult(false, error_message) but don't tell LLMs what to do next. E.g., 'Failed to delete /path/to/file', should the agent retry, check permissions, or ask the user?
