Why ToolWeaver

Designed for production

  • Package-first: pip install and use inside your apps—no heavy framework
  • Guardrails built in: cost caps, concurrency, failure thresholds, timeouts
  • Safe by default: secrets redactor, PII filtering, template sanitization, sandbox

Developer experience

  • Three ways to register tools: decorators, templates, YAML
  • Discovery/search: domain, keywords, semantic search
  • Aggregation patterns: majority vote, rank by metric, best result, collect-all

Performance

  • Dual-layer cache with file fallback
  • Idempotency caching for instant replays
  • Demonstrated speedups in tutorials (1.7x for batch parallelism)

Fit

  • Use with planners or call programmatically
  • Expose tools via REST quickly (FastAPI adapter)
  • Extend via plugins and share via skills
