All notable changes to this project are documented here.

The format is based on Keep a Changelog, and this project broadly follows Semantic Versioning: each new wave of skills bumps the major version, extensions and fixes bump minor / patch.

16.0.0 — Multi-Platform — 2026-06-17

The library stops being Claude-only and becomes a portable, single-source-of-truth project.

Added

• Hermes Agent support (native). scripts/sync-hermes-skills.py installs the canonical skills/ into ~/.hermes/skills/ (copy or --link symlink). Hermes reads the same open SKILL.md standard, so there is no format conversion — it auto-discovers skills by their description, exactly like Claude Code.
• Multi-platform export generator. scripts/build-exports.mjs renders every skill into platform-ready files under exports/ from a single source of truth (the SKILL.md body), so content is never maintained twice. Ships ChatGPT (exports/chatgpt/.../SYSTEM_PROMPT.md) and Google Gemini (exports/gemini/.../GEM_INSTRUCTIONS.md) exports, plus a PLATFORMS registry that makes adding Cursor/etc. a few lines. Includes a --check mode and a check-generated CI workflow that fails if exports or web/skills.json drift.
• Programmatic helpers (stdlib Python) for three flagship skills. Each runs with zero dependencies and computes part of the work instead of estimating by hand:
  • sprint-planning/scripts/capacity_calculator.py — recommended sprint commitment from team size, availability, velocity, and carry-over (caps at 80% of velocity).
  • rice-prioritisation/scripts/rice_calculator.py — calculates and ranks RICE scores from JSON/CSV and auto-flags quick wins, moonshots, and low-confidence items.
  • cs-health-scorecard/scripts/health_score.py — weighted health total out of 100 with RAG banding and weight validation.
• CHANGELOG.md — this file, back-filled from the release history.
• SKILL-AUTHORING-STANDARD.md — the canonical structure every SKILL.md follows (frontmatter, required sections, quality bar, anti-patterns).
• Skill tiers — a TIERS.md reference and README section marking skills as Production-Ready, Stable, or Experimental so new users start with the strongest work.
• Cross-tool compatibility — README now documents which platforms the skills work on (Claude Code and Hermes natively; the SKILL.md bodies port to other agents and chat LLMs).
• Skill Playground upgrades — the hosted web app gains a tier filter and per-tile tier badges, plus a "Use this skill in another tool" panel that copies the instructions formatted for ChatGPT, Gemini, or raw. Tier data comes from a single machine-readable source, skill-tiers.json.
• Related Projects — README section linking to other community Claude Skills libraries and the awesome-claude-skills / awesome-claude-code lists.

Changed

• Multi-platform rebrand. README title, tagline, intro, and badges now position the library for Claude, ChatGPT, Gemini, and Hermes — not Claude alone. (The repository name, marketplace ID, and install commands are unchanged.)
• SECURITY.md supported-versions table updated to the v16 release line.

Fixed

• web/skills.json is now deterministic. Removed the wall-clock generatedAt field (it was unused by the UI and made every rebuild differ), so the new check-generated CI step can reliably verify the index is in sync with the source skills.

15.0.0 — Skill Playground — 2026-06-09

Added

• Skill Playground — a zero-backend browser app (web/) to run any skill with your own Claude API key. Tile gallery with search + bundle filter, click-to-run forms generated from each skill's Required Inputs, live streaming output with copy / download-as-.md, and a model picker. web/build-skills.mjs generates skills.json; a GitHub Actions workflow auto-deploys to GitHub Pages on every push to main.

Fixed

• Mid-stream API errors now surface to the user instead of being silently swallowed.
• max_tokens raised to 8192 to avoid truncating long outputs.

14.0.0 — Writers & Content Creators + 7 Community Skills

Added

• New profession Writers & Content Creators (pm-writers): Instagram Post Downloader, AEO Optimizer, Thumbnail Creator, Substack Notes Scraper, Notes Humanizer.
