# Pi Packages Pi extended itself through npm packages (`pi install npm:`), each bundling extensions, skills, prompts, or themes. The harness is retired (2026-10-18); this page is the merged census of what was installed — one row per package, detail pages kept as historical records. ## Installed packages | Package | Version | Detail | What it did | |---------|---------|--------|-------------| | `@wierdbytes/pi-peon` | 0.1.1 | [Pi Peon](pi-peon.md) | CESP/OpenPeon sound-pack player for pi lifecycle events. | | `pi-web-access` | 0.22.0 | [Pi Web Access](pi-web-access.md) | Web search, URL fetching, GitHub cloning, PDF extraction, video understanding. | | `pi-subagents` | 0.36.0 | [Pi Subagents](pi-subagents.md) | Core subagent delegation — chains, parallel execution, TUI clarification. | | `pi-browser-use` | — | [Pi Browser Use](pi-browser-use.md) | Browser automation wrapping chrome-devtools-mcp behind a `browser_` prefix. | | `pi-permission-system` | — | [Pi Permission System](pi-permission-system.md) | Permission enforcement and policy configuration; upstream docs are 10 interlinked pages. | ## Where the concepts live now * Subagent delegation → [OMP Subagent Limits & Fan-out Policy](/core/subagent-limits.md) (live caps). * Skill/package distribution → [Skills](/skills/index.md) (Agent Skills standard + `skills` CLI). * Web access → the `web/searxng` provider and MCP tooling; see [Agentic web research](/agentic-web-research/index.md). ## See Also - [Pi Settings System](/core/settings.md) — where these packages were registered (`settings.json` archive). - [Pi Configuration](/pi/index.md) — pi-era overview.
