Claude Code Skills

A collection of skills for Claude Code - specialized knowledge modules that turn Claude into an expert at specific tasks.

What are Skills?

Skills are markdown files that give Claude Code domain expertise. Instead of explaining what you want every time, you invoke a skill and Claude knows exactly what to do.

Available Skills

Skill	Description
sync-context	End-of-session context sync. Reviews what was learned and persists it into project context files so the next session starts up to date.
skillify	Turns the session you just finished into a reusable skill. Reads the JSONL, interviews you in four structured rounds, writes a clean SKILL.md with per-step success criteria.
skill-tutor	Personal AI tutor with spaced repetition. Creates tutorials using YOUR projects, tracks learning progress, quizzes you at optimal intervals.
optimize-prompt	Evolves prompts using genetic algorithms. Give it test cases, it finds the prompt that works.
deploy-agentcore	Deploy Python agents to AWS Bedrock AgentCore. Serverless hosting with memory, auth, and observability.
chrome-extension	Build Chrome extensions with Manifest V3. Scaffolding, patterns, debugging.
model-audit	Reads the dispatch log written by the model-routing hook and shows whether subagents are running on the model tiers you intended. Pairs with hooks/model-routing.

Hooks

Mechanical guardrails that run in the Claude Code harness — not skills, but artifacts you wire into ~/.claude/settings.json.

Hook	Description
model-routing	PreToolUse hook that blocks Agent/Task dispatches without an explicit model parameter. Kills the silent default where subagents inherit the parent's model (almost always Opus). Ships with the rule, the hook script, an audit script, and a settings snippet. Pairs with the model-audit skill.

In Claude Code, either:

• Invoke directly: /skill-tutor, /optimize-prompt, etc.
• Use trigger phrases: "teach me", "optimize this prompt", "deploy to agentcore"
