Loading ToolBench
A CLI tool for reducing and analyzing noisy shell output, test results, logs, and diffs. Provides effort estimation for tasks and integrates with Claude and Codex as a skill.
Alembic exhibits significant definition quality gaps. Tool names lack clear action verbs (e.g., 'exec', 'effort', 'benchmark' are vague). Descriptions are present but generic (10-50 chars for most tools). Input schemas exist but lack comprehensive parameter descriptions, many parameters have minimal or missing guidance on valid values, ranges, or constraints. Output schemas are not documented. Error handling and recovery guidance are absent. The 'exec' tool is particularly problematic: it accepts arbitrary commands with minimal validation, no output format specification, and no error recovery hints. No tool demonstrates idempotent operation patterns or confirmation steps for destructive operations.
Run benchmarks to measure output reduction effectiveness
Diagnose Alembic installation and configuration
Analyze task effort and provide recommendations for thinking level
Execute a command and reduce its output based on a question and mode
Manage Alembic hook configuration for Claude or Codex
Initialize Alembic guidance in AGENTS.md or CLAUDE.md
Tool names lack action verbs. 'exec', 'effort', 'benchmark', 'doctor', 'hook-config' do not clearly signal what action the LLM should expect. Recommend: 'run_command', 'analyze_effort', 'measure_benchmark', 'diagnose_installation', 'configure_hooks'.
Parameter descriptions are minimal or absent. 'mode' in exec accepts 11 values (auto, tests, actions, mcp, docker, k8s, logs, diff, grep, watch, data) with no guidance on when to use each. 'level' (ash, ember, flame) lacks explanation of what each level controls. LLMs cannot infer intent from enum names alone.
No output schemas documented. Tools return unstructured text or JSON without specifying field names, types, or structure. LLMs cannot plan downstream calls or extract required data reliably.

exec tool accepts arbitrary shell commands with no validation, sanitization, or error recovery guidance. No mention of command injection risks, timeout handling, or what to do if a command fails. Violates security and error-handling patterns.
hook-config and init are write operations but lack confirmation/dry-run patterns. No guidance on what happens if configuration is invalid or if init overwrites existing files. Agents cannot safely plan these operations.
