+### Pi
+
+Install Superpowers as a Pi package from this repository:
+
+```bash
+pi install git:github.com/obra/superpowers
+```
+
+For local development, run Pi with this checkout loaded as a temporary package:
+
+```bash
+pi -e /path/to/superpowers
+```
+
+The Pi package loads the Superpowers skills and a small extension that injects the `using-superpowers` bootstrap at session startup and again after compaction. Pi has native skills, so no compatibility `Skill` tool is required. Subagent and task-list tools remain optional Pi companion packages.
+
 ## The Basic Workflow
 
 1. **brainstorming** - Activates before writing code. Refines rough ideas through questions, explores alternatives, presents design in sections for validation. Saves design document.

+# Pi Tool Mapping
+
+Pi supports Superpowers skills natively through skill discovery and `/skill:name` commands. It does not expose Claude Code's `Skill` tool.
+
+When a Superpowers skill mentions Claude Code tool names, use these Pi equivalents:
+
+| Superpowers / Claude Code name | Pi equivalent |
+| --- | --- |
+| `Skill` | Pi native skills: load the relevant `SKILL.md` with `read`, or let the human use `/skill:name` |
+| `Read` | `read` |
+| `Write` | `write` |
+| `Edit` | `edit` |
+| `Bash` | `bash` |
+| `Grep` | `grep` when active; otherwise `bash` with `rg`/`grep` |
+| `Glob` | `find` or `bash` with shell globs |
+| `LS` / `List` | `ls` when active; otherwise `bash` with `ls` |
+| `Task` | Use an installed subagent tool such as `subagent` from `pi-subagents` if available |
+| `TodoWrite` | Use an installed todo/task tool if available, otherwise track tasks in the plan or `TODO.md` |
+
+## Skills
+
+Pi discovers skills from configured skill directories and installed Pi packages. A Superpowers Pi package should expose `skills/` through its `pi.skills` manifest entry. The agent should still follow the Superpowers rule: when a skill applies, load and follow it before responding.
+
+## Subagents
+
+Pi core does not ship a standard subagent tool. The `pi-subagents` package is a strong optional companion and provides a `subagent` tool with single-agent, chain, parallel, async, forked-context, and resume/status workflows. If no subagent tool is available, do not fabricate `Task` calls; execute sequentially in the current session or explain that the optional subagent capability is not installed.
+
+## Task lists
+
+Pi core does not ship a standard task-list tool. If a todo/task extension is installed, use its documented tool. Otherwise use Superpowers plan files, checklists in Markdown, or a repo-local `TODO.md` for task tracking.
