alexei-led/cc-thingz v1.3.0 on GitHub

What's New

cc-thingz now works across three AI coding CLI tools: Claude Code, OpenAI Codex CLI, and Google Gemini CLI. All 30 skills are served with platform-optimized instructions tuned for each model family.

Cross-Platform Skill Delivery

Skills are classified into three tiers and processed by a build system (generate-overlays.py) that produces platform-optimized variants:

Tier	Count	What Happens
GREEN	15	Shared body — CC frontmatter stripped, platform preamble injected
YELLOW	8	CC-ONLY body sections stripped, frontmatter cleaned, preamble injected
RED	6	Full hand-authored overlays optimized for o3/codex-1 instruction following

The 6 RED skills with hand-crafted Codex overlays: reviewing-code, fixing-code, improving-tests, brainstorming-ideas, deploying-infra, testing-e2e.

OpenAI Codex CLI Support

.codex-plugin/plugin.json manifests for all 9 plugins
.agents/plugins/marketplace.json — Codex plugin marketplace
Platform-optimized skills in skills-codex/ directories
Skills include agentic anchors: persistence, tool-call encouragement, planning

Google Gemini CLI Support

gemini-extension.json at repo root + 9 per-plugin manifests
Installable as a Gemini CLI extension: gemini extensions install https://github.com/alexei-led/cc-thingz
GEMINI.md context file with skill imports
Skills include Gemini-specific anchors: self-critique, risk assessment, output completeness

Build System

scripts/generate-overlays.py — builds skills-codex/ from CC sources
 sentinels for body section stripping
scripts/preambles/platform.md — shared agentic anchors for non-Claude models
make overlays / make validate-overlays targets
CI builds overlays before validation

Other Improvements

GitHub Actions upgraded to Node.js 24 (actions/checkout@v5, FORCE_JAVASCRIPT_ACTIONS_TO_NODE24)
smart-lint.sh: skip symlinks in markdown formatting
All plugin versions synced across CC, Codex, and Gemini manifests
