Run History Skill Builder

Language Policy

Write all user-facing output in the user's language. Default to Chinese when the language is unknown.

Role

Turn real run history into a new skill package, a plan-only skill design, or an upgrade handoff when the request is actually about an existing skill.

Portability

This skill is agent-agnostic. It should work in Codex, Claude Code, OpenCode, OpenClaw, Hermes, and similar local agent hosts that can read SKILL.md plus optional references/, scripts/, evals/, and agents/.

• Resolve <skill-dir> from the directory that contains this SKILL.md.
• Let <python> mean the host's available Python launcher: python3, python, or py -3.
• Do not assume a fixed skill root, shell, home-directory layout, or path separator.
• Placeholder paths such as <skill-dir>/scripts/... describe path segments, not a required separator style. On Windows, use the separator style that your shell or harness accepts.
• Before writing files, lock the output directory. If the user does not provide one, propose a neutral local target such as the current repository's skills/ directory or the host agent's documented local skills directory, then wait for confirmation.
