Hullo 👋 @hao-cyber

I ran your skills through `tessl skill review` at work and found some targeted improvements. Here's the full before/after:

| Skill | Before | After | Change |
|-------|--------|-------|--------|
| skill-dev | 86% | 90% | +4% |

<details>
<summary>Changes made</summary>

- **Added explicit lifecycle flow** with numbered stages and validation gates (create → use → reflect → evaluate → maturity check → publish), with fail-loop-back mechanism
- **Added concrete examples to Degrees of Freedom** — replaced abstract descriptions with specific examples at each freedom level (e.g., `sys.exit(1)` for low freedom)
- **Added Quick Example section** showing a real reflect → evaluate → publish workflow with executable commands (`grep`, `run_eval.py`, `publish.py`)
- **Removed redundant "Concise is Key" subsection** — its guidance overlapped with Writing Guidelines
- **Tightened Writing Guidelines** — consolidated into four crisp bullets with a litmus test

</details>

Honest disclosure — I work at @tesslio where we build tooling around skills like these. Not a pitch - just saw room for improvement and wanted to contribute.

Want to self-improve your skills? Just point your agent (Claude Code, Codex, etc.) at [this Tessl guide](https://docs.tessl.io/evaluate/optimize-a-skill-using-best-practices) and ask it to optimize your skill. Ping me - [@popey](https://github.com/popey) - if you hit any snags.

Thanks in advance 🙏
