The check-generated CI step was failing with "web/skills.json is stale"
because build-skills.mjs stamped a wall-clock generatedAt into the file, so
every rebuild differed and git diff --exit-code never matched.
- web/build-skills.mjs: drop the unused generatedAt timestamp -> deterministic
output the CI staleness check can verify. Also tags each skill with its tier.
- skill-tiers.json: single machine-readable source for tier membership
(Production-Ready / Experimental); TIERS.md points to it.
Playground upgrades (hosted on GitHub Pages):
- Tier filter (Production-Ready / Stable / Experimental) + per-tile tier badges.
- "Use this skill in another tool" panel: copy the instructions formatted for
ChatGPT, Gemini, or raw — mirrors the generated exports/ files.
- web/README documents the new options and the deterministic build.

Five improvements to position the library as a serious engineering project:
1. Cross-tool compatibility — new README "Works With" section honestly
documenting where skills run (Claude Code natively; SKILL.md bodies
port to other agents and chat LLMs as system prompts).
2. Python helper scripts (stdlib-only) for the three strongest skills:
- sprint-planning: capacity_calculator.py (recommended commitment)
- rice-prioritisation: rice_calculator.py (ranks, flags quick wins/moonshots)
- cs-health-scorecard: health_score.py (weighted total + RAG)
Each is wired into its SKILL.md and synced to the plugin copies.
3. Explicit skill tiering — TIERS.md + README section marking 46
Production-Ready skills and calling out Experimental (external-dependency)
ones; everything else is Stable.
4. Repository hygiene — new CHANGELOG.md (Keep a Changelog format) and
SKILL-AUTHORING-STANDARD.md; refreshed SECURITY.md version table and
helper-script disclosure; added .gitignore.
5. Related Projects — README section linking to alirezarezvani/claude-skills
and the major awesome-claude-skills / awesome-claude-code lists.
