Miko: required Skill checks for Claude Code and Codex

Your coding agent says it read the Skill, but did it really?

Miko intercepts file edits at the Hook layer. If your agent hasn't read the required Skill first, Miko rejects the edit and provides a clear, observable recovery path. It runs locally, zero-dependency, makes no LLM calls, and is free and open source.

Who needs this?

• You use Claude Code or Codex CLI, wrote project Skills/instructions, but aren't sure if the agent follows them.
• You want a hard check before file edits instead of relying solely on prompt instructions.
• You want Skill loading and checks to be observable, rejectable, and recoverable.

How Miko differs

Unlike static Skill linters or security scanners, Miko works at the runtime Hook layer—intercepting the agent's actual file edit tool calls in real time rather than statically analyzing Skill files.
