cc-thingz — Coding Companion

Portable skills, agents, hooks, and Pi-native extensions for Claude Code, Codex CLI, GitHub Copilot, Cursor, Grok, and Pi. Gemini is retired.

Build

Requires Agent Bundler with build, check, and package, plus support for per-agent sidecars, declared hook environments, Pi-native assets, and Codex project-agent profiles. Verify packaging support:

agbun package --help

Build and check the complete generated tree:

make build
make check

make build is a direct agbun build --root . invocation. make check runs the non-mutating agbun check --root . drift gate. Agent Bundler replaces the configured dist/ output tree during builds, so do not edit generated files.

Skills use Agent Bundler overlays for target-specific frontmatter, body, and support-file changes. Target-wide preambles are composition entries in agentbundle.json. Canonical source remains readable Markdown with YAML frontmatter; Agent Bundler emits normalized JSON frontmatter.

Package membership is defined by src/.agentbundler/packages/*.json. Each package lists exact skill and agent asset paths. Root marketplace files are routing wrappers only: their entries point into dist/<target> and contain no independent package trees. Do not edit dist/ or give the wrappers independent metadata.

Targets and output

Target	Output	Package contract
Claude Code	dist/claude/<package>/	Marketplace packages, agents, and hooks
Codex CLI	dist/codex/<package>/	Plugin packages plus .codex/agents/*.toml profiles
Pi	dist/pi/	Aggregate package, typed hooks, and native extensions
GitHub Copilot	dist/copilot/<package>/	Marketplace packages, agents, and hooks
Cursor	dist/cursor/<package>/	Marketplace packages, agents, and supported hooks
Grok Build	dist/grok/<package>/	Marketplace packages, agents, and hooks
Gemini CLI	none	Retired

Release packages

agbun package --root . --out DIR creates deterministic, target-native release archives:

• cc-thingz-claude.tar.gz
• cc-thingz-codex.tar.gz
• cc-thingz-pi.tgz
• cc-thingz-copilot.tar.gz
• cc-thingz-cursor.tar.gz
• cc-thingz-grok.tar.gz

The release workflow attaches all six files. Each archive expands directly to the native package or marketplace root shown above. The Codex archive also includes separate .codex/agents/*.toml profiles; they are not plugin contents. Installation and marketplace registration use the target vendor's CLI; Agent Bundler does not mutate user configuration or publish to a vendor registry.

Repository-root installation

Compatibility manifests at the repository root preserve Git and local-path installation while keeping dist/<target> canonical:
