claude-dev-toolkit

Set up Claude Code well and build with it.

• starter-kit/ — drop-in CLAUDE.md + MEMORY.md + ERRORS.md + anti-style.md with an install.py (skips existing files) and tests. The highest-leverage thing for Claude Code quality.
• secrets-manager/ — keep API keys out of Claude Code's on-disk JSONL transcripts: a setup guide + a stdlib secret_env.py helper (with tests).
• frontend-polish/ — a screenshot → self-review → refine loop that composes the official frontend-design skill instead of reinventing aesthetics.
• a2a-agent-tutorial/ — a minimal, dependency-light Agent2Agent (A2A) demo in Python (pluggable LLM, runs offline, tested).
• commands-reference.md — which "Claude commands" are real native features vs. just renamed prompts.

Run any project's tests with python -m pytest <subfolder>.

Use in Claude chat (claude.ai)

These are Claude Code / runtime tools (installers, a secrets helper, a Playwright screenshot loop, runnable agent code) — they need a local environment, so they aren't claude.ai chat skills. The chat-usable skills live in the sibling repos claude-thinking-tools, claude-writing-tools, and claude-everyday-tools (see their skills/).
