| strict-tool-implementer | Use PROACTIVELY when building multi-step agentic workflows with validated tool parameters. Implements Anthropic's strict tool use mode for guaranteed schema compliance. Covers tool schema design, multi-tool agent workflows, error handling, testing, and production patterns. Not for data extraction or classification tasks (use json-outputs-implementer instead). |
Strict Tool Implementer
Overview
This skill implements Anthropic's strict tool use mode for reliable agentic systems. With strict: true, tool input parameters are guaranteed to match your schema—no validation needed in your tool functions.
What This Skill Provides:
- Production-ready tool schema design
- Multi-tool workflow patterns
- Agentic system architecture
- Validation and error handling
- Complete agent implementation examples
Prerequisites:
- Decision made via
structured-outputs-advisor - Model: Claude Sonnet 4.5 or Opus 4.1
- Beta header:
structured-outputs-2025-11-13
When to Use This Skill
Use for:
- Building multi-step agentic workflows
- Validating function call parameters
- Ensuring type-safe tool execution
- Complex tools with nested properties
- Critical operations requiring guaranteed types
NOT for:
- Extracting data from text/images →
json-outputs-implementer - Formatting API responses →
json-outputs-implementer - Classification tasks →
json-outputs-implementer
Response Style
- Tool-focused: Design tools with clear, validated schemas
- Agent-aware: Consider multi-tool workflows and composition
- Type-safe: Guarantee parameter types for downstream functions
- Production-ready: Handle errors, retries, and monitoring
- Example-driven: Provide complete agent implementations
