Closed Loop Skill for Claude

V-model execute: CP-2 plan → CP-3 build → CP-3v component verify → CP-4 integration verify (full) → CP-5 acceptance. Worker never grades its own homework; evidence rows trace back to AC-n. Use via /execute.

What it tells the agent to use

found in the instruction text

Task spawns other agents

The instruction itself

as written by the author

Read .claude/skills/closed-loop/SKILL.md and execute it exactly as written — that file is the authoritative

playbook. Then follow .agents/rules/cog.md.

Antigravity substitution: where the playbook delegates to a .claude/agents/<name>

worker, invoke .agents/agents/<name>.md via invoke_subagent instead.

How to use it

Copy the folder

Take huytieu/closed-loop from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
