Developer & AI-Agent QA Pack — 10 Claude Skills

Ten SKILL.md files for developers who work with AI agents: review diffs, check whether tests still prove anything, verify an agent's 'done' claim, triage silent browser-automation failures, read LLM API error headers.

How to use: unzip, copy the folders you want into your skills directory (for example `~/.claude/skills/`), then ask your agent to run the skill by name. Works with any agent that reads SKILL.md.
