the support matrix before
installing.

Quick Start
Claude Code
Add the marketplace and install any of its 36 listed plugins:
Verify installation:
Invoke an installed skill as / : , using the skill's
frontmatter name. For example: /qa-walkthrough-pr:qa-walkthrough-pr.
Codex
Codex's native catalog currently offers codex, hotline, and the five PR plugins
(address-pr-comments, qa-walkthrough-pr, update-pr-description,
walk-through-work-history, watch-pr-then-action):
Open /plugins in Codex to browse configured marketplaces, or run
codex plugin list --available --json in a terminal. Start a new session after
installation, then mention a skill as $ : ; for example,
$codex:fable-mode.
To install one self-contained repository skill instead of a whole plugin, see
standalone Codex skills. For commands,
updates, catalog scope, and all 37 plugin names, see the
compatibility guide.

📞 hotline
Cross-workspace communication for agent sessions — dial another workspace to ask questions, delegate work, or collaborate. Claude Code and Codex can place calls; the current launch transport starts Claude Code receivers. Caller identity comes from Claude Code's native CLAUDE_CODE_SESSION_ID (or Codex's thread ID), with a bundled fingerprint fallback for older clients.
**Install:** claude plugin install hotline@jtsternberg or codex plugin add hotline@jtsternberg
🧠 thinking-tools
Metacognitive reasoning frameworks for careful decision-making. Ships chestertons-fence (investigate before removing), pink-elephant (rewrite counterproductive prohibitions as positive directives), interview-mode (after two rejected drafts of the same artifact, stop generating variants and interview the user to build from their own wording), no-meat-proxy (rewrite what you're about to hand over so the reader can relay it in their own words instead of forwarding your text verbatim), and dont-lead-the-witness (when you want a genuine response — testing an agent, asking for a review, questioning the user — ask the way the real situation would, with no hint of the answer you expect, and judge by observation).
**Install:** claude plugin install thinking-tools@jtsternberg
