Agent SDK Meta Skill

🚨 MANDATORY: Invoke docs-management First

STOP - Before providing ANY response about Claude Agent SDK:

  1. INVOKE docs-management skill
  2. QUERY using keywords: Agent SDK, TypeScript SDK, Python SDK, sessions, custom tools, permissions, or related topics
  3. BASE all responses EXCLUSIVELY on official documentation loaded

Skipping this step results in outdated or incorrect information.

Verification Checkpoint

Before responding, verify:

  • Did I invoke docs-management skill?
  • Did official documentation load?
  • Is my response based EXCLUSIVELY on official docs?

If ANY checkbox is unchecked, STOP and invoke docs-management first.

Overview

Central authority for Claude Agent SDK (TypeScript and Python SDKs). This skill uses 100% delegation to docs-management - it contains NO duplicated official documentation.

Architecture: Pure delegation with keyword registry. All official documentation is accessed via docs-management skill queries.

Reference Loading Guide

This skill follows a pure delegation architecture with three loading layers:

Layer 1: Always in Context

  • SKILL.md (this file) - Keyword registry, decision trees, delegation patterns

Layer 2: On-Demand via docs-management

All official Agent SDK documentation is accessed through docs-management queries:

Delegation Patterns

Standard Query Pattern

User asks: "How do I create a custom tool in the Agent SDK?"

1. Invoke docs-management skill
2. Use keywords: "custom tools SDK", "creating custom tools"
3. Load official documentation
4. Provide guidance based EXCLUSIVELY on official docs

Multi-Topic Query Pattern

User asks: "I want to build an agent with sessions, custom tools, and cost tracking"

1. Invoke docs-management skill with multiple queries:
   - "session management SDK", "session resumption"
   - "custom tools SDK", "creating custom tools"
   - "cost tracking SDK", "token usage"
2. Synthesize guidance from official documentation

Troubleshooting Pattern

User reports: "My session resumption isn't working"

1. Invoke docs-management skill
2. Use keywords: "session management SDK", "resume option", "session ID"
3. Check official docs for session patterns
4. Guide user through proper session handling

Related Skills

Skills that work well with agent-sdk-development:

  • docs-management - Primary delegation target; provides all official Agent SDK documentation
  • mcp-integration - MCP server configuration; Agent SDK can integrate with MCP servers
  • settings-management - Settings configuration; SDK respects Claude Code settings
  • hook-management - Hook configuration; SDK supports hooks via programmatic loading
  • current-date - Get current UTC date for version history and audit timestamps

Delegation example:

When working with Agent SDK + MCP integration:
1. Use agent-sdk-development for SDK-specific guidance
2. Use mcp-integration for MCP server configuration
3. Both skills delegate to docs-management for official documentation

Run a health check on an existing project: dependency audit, security scan, test runner detection, CI/CD evaluation, and missing configuration analysis. Maps the three execution gates (pre/in/post) from /10x-bootstrapper to an assessment framework for existing codebases. Reads optional context/foundation/stack-assessment.md from /10x-stack-assess to focus checks on identified gaps. Writes context/foundation/health-check.md with findings, prioritized fixes, and an agent-readiness verdict. Use when the user has an existing project and wants to verify its health before working with an agent. Trigger phrases: "health check", "check my project", "audit my project", "is my project healthy", "sprawdź projekt", "audyt projektu", "health-check", "project health". Use AFTER /10x-stack-assess (brownfield chain), BEFORE agent onboarding (m1-l4).
