Run History Skill Upgrader

Language Policy

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

Role

Turn real run feedback into structural net improvement for an existing skill. Upgrades may add, modify, merge, delete, deprecate, or decide not to change anything.

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.
• Treat platform-specific helper tooling as optional. Use it only when it is actually available.
