Create, improve, and validate agent skills using a SkillOpt-inspired workflow: scored evidence, bounded add/delete/replace edits, validation gates, rejected-edit memory, and compact deployable SKILL.md artifacts.
Passed 17 of 20 test cases with the skill, and 11 of 20 without it.

One of 7 test cases the skill fixed. Same model, same prompt, with and without the skill.
When executing environment detection for a skill optimization session, the command `rg --version` fails because ripgrep is not installed. What fallback command should be run, and what state marker should be recorded?
| Checked | Without skill | With skill |
|---|---|---|
| Uses grep --version as the fallback detection command when ripgrep is unavailable. | Passed | Passed |
| Outputs no-fast-search as the detected state marker if both ripgrep and grep fail. | Missed | Passed |
The instructions your model reads when the skill loads.
Use this skill to write or improve agent skills as compact, testable procedural artifacts. The method is inspired by SkillOpt: treat one SKILL.md as the trainable state, make bounded edits, accept changes only after validation, and keep rejected edits as negative feedback.
中文使用原则：当用户用中文描述需求时，用中文产出 brief、验证说明和最终回复；SKILL.md 的技术标识、文件名、命令、frontmatter 字段保持英文或 ASCII。触发词、README、模板和说明应尽量中英文双语，方便中文用户使用，也方便 GitHub 搜索。
Run only the checks that are relevant to the current environment. If a command is unavailable, use the fallback path and record the gap.
Detection commands:
!pwd || cd
!rg --version || grep --version || echo "no-fast-search"
!git --version || echo "no-git"
!rg --files -g SKILL.md . || find . -maxdepth 4 -name SKILL.md || dir /s /b SKILL.md
!test -f SKILL.md && echo "current-skill" || echo "no-current-skill"
Decision tree:
| Detected state | Path |
|---|---|
| User provided a workflow but no existing skill | Create a new skill from a seed draft |
User provided an existing SKILL.md | Improve it with bounded edits |
| User provided tasks, expected outputs, tests, or scorer | Use scored validation gate |
| No scorer or test tasks are available | Use static rubric + 2-3 dry-run prompts and mark as dry_run |
| Git is available and workspace is a repo | Keep before/after diff and avoid unrelated changes |
| Git is unavailable | Keep an edit log in rejected_edits.md / validation_notes.md |
Exit gate: identify mode (create, improve, or evaluate), available validation path, target runtime, and output location.
Extract the minimum brief before drafting. Do not stall if fields are missing; use the defaults table.
| Parameter | Default | Rationale |
|---|---|---|
| Target runtime | Codex-compatible SKILL.md | Current environment uses Codex skills |
