Run in Claude Code 2.1.292 or later:

/plugin marketplace add michael-denyer/pstack-claude
/plugin install pstack@pstack-claude

Claude Code leaves auto-update off for third-party marketplaces, so pstack stays on the version you installed. To turn it on, run /plugin, open the Marketplaces tab, select pstack-claude, and choose Enable auto-update. To update once by hand, run claude plugin update pstack@pstack-claude.

Run in your terminal:

codex plugin marketplace add michael-denyer/pstack-claude
codex plugin add pstack@pstack-claude

Run in your terminal:

pi install git:github.com/michael-denyer/pstack-claude

The package loads the skills and the pstack Pi extension, which adds the subagent, question, and wake-up tools the skills use, plus /loop and the routing instruction. Invoke a skill with /skill:.

Run in your terminal:

copilot plugin marketplace add michael-denyer/pstack-claude
copilot plugin install pstack@pstack-claude

This installs pstack for the Copilot CLI and the GitHub Copilot app, which share ~/.copilot. Start a new session afterwards. Copilot ships no default pstack models, so the first skill that needs one runs setup-pstack to pick from the models your account lists, and later sessions reuse that choice.

The Copilot build is tested on Copilot CLI 1.0.87 through 1.0.92. On those versions the routing hook's context reaches the session alongside other plugins' session-start context. If a later version keeps only one plugin's context, setup-pstack offers a standing instruction for ~/.copilot/copilot-instructions.md instead. On 1.0.92, once the CLI caches its computer-use experiment assignment, copilot -p sessions list no plugin skills and a skill call returns "Skill not found". Interactive sessions, the hooks, and the agents are unaffected.

Run in your terminal:

git clone https://github.com/michael-denyer/pstack-claude
cd pstack-claude
muse plugins install ./plugins/pstack
muse plugins approve pstack

The first command installs the native Muse plugin bundle. The second approves its SessionStart hook and agent definitions, which Muse runs only after approval. Start a new session afterwards. Invoke a skill with / (for example /poteto-mode), which Muse lists for each user-invocable skill.

OpenCode (the CLI and the desktop app), Gemini CLI, Prime Agent, and skills-only Codex installs read skills from ~/.agents/skills/. Run in your terminal:

git clone https://github.com/michael-denyer/pstack-claude
cd pstack-claude
mkdir -p ~/.agents/skills
for s in plugins/pstack/skills/*/; do
  target=~/.agents/skills/"$(basename "$s")"
  test -e "$target" || test -L "$target" || ln -s "$(pwd)/$s" "$target"
done

To update, run git pull in the clone, then run the for loop again to link skills added since the last run. These installs have no routing hook, so ask for poteto-mode by name or add a standing instruction to the harness's instruction file. See shared installation for per-harness notes and uninstalling.
