pi-amplike

Pi skills and extensions that give Pi similar capabilities to Amp Code out of the box.

Features

Session Management

• Handoff - Create a new focused session with AI-generated context transfer:
  • /handoff <goal> command - Manually create a handoff session (potentially with -mode <name> / -model <name> parameter to switch models for the new session)
  • handoff tool - The agent can invoke this (with optional mode/model parameters) when you explicitly request a handoff
• session_query tool - The agent in handed-off sessions automatically gets the ability to query the parent session for context, decisions, or code changes; analysis uses the queried session's own model
• Use /resume to switch between and navigate handed-off sessions

Subagents and BTW

• subagent tool - The agent can create one or multiple parallel task-focused, non-interactive subagents to save context and speed up work
• /btw <prompt> command - Same semantics as in Claude Code, basically a user-triggered subagent running and finishing asynchronously and independently on the main agent

Permissions

• /permissions command toggles bash command allow/deny permissions, directly read from AmpCode's configuration files.

Prompt Modes

• /mode command with interactive mode selector/configuration UI (a mode is a model + thinking + color preset, active mode is shown in prompt editor border)
• Shortcuts:
  • Ctrl+Shift+S - mode selector
  • Ctrl+Space - cycle modes

Web Access

• web-search - Search the web via Jina Search API
• visit-webpage - Extract webpage content as markdown (using Jina API), or download images

Amp Skill Compatibility

• Auto-loads Amp skill directories when present:
  • ~/.config/agents/skills
  • ~/.config/amp/skills
  • .agents/skills (project-local)

Installation

Option A: Install from npm (recommended)

pi install npm:pi-amplike

Option B: Install from git

pi install https://github.com/pasky/pi-amplike

Option C: Local development

git clone https://github.com/pasky/pi-amplike ~/.pi/packages/pi-amplike
cd ~/.pi/packages/pi-amplike
npm install

Then add "packages/pi-amplike" to the "packages" array in ~/.pi/agent/settings.json.

Setup

Get a Jina API key for web skills (optional, works with rate limits without it):

export JINA_API_KEY="your-key"  # Add to ~/.profile or ~/.zprofile

Get an API key at jina.ai. Even if you charge only the minimum credit, it's going to last approximately forever.

Usage

Session Handoff

When your conversation gets long or you want to branch off to a focused task, you can use handoff in two ways:

Manual handoff via command:

/handoff now implement this for teams as well
/handoff -mode rush execute phase one of the plan
/handoff -model anthropic/claude-haiku-4-5 check other places that need this fix

Optional flags (can be combined):

• -mode <name> — start the new session in a named mode (e.g. rush, smart, deep)
• -model <provider/id> — start the new session with a specific model (e.g. anthropic/claude-haiku-4-5)

The handoff summary is always generated with the current session's model before switching.

Agent-invoked handoff: The agent can also initiate a handoff when you explicitly ask for it:

"Please hand this off to a new session to implement the fix"
"Create a handoff session to execute phase one"

The handoff tool also accepts optional mode and model parameters.

Both methods create a new session with:

• AI-generated summary of relevant context from the current conversation
• List of relevant files that were discussed or modified
• Clear task description based on your goal
• Reference to parent session (accessible via session_query tool)

Session Navigation

Use Pi's built-in /resume command to switch between sessions, including handed-off sessions. The handoff creates sessions with descriptive names that make them easy to find.

Querying Past Sessions

The session_query tool lets the model look up information from previous sessions. It's automatically used when a handoff includes parent session reference, but can also be invoked directly. The analysis call uses the queried session's own model (falling back to the current model if unavailable):

session_query("/path/to/session.jsonl", "What files were modified?")
session_query("/path/to/session.jsonl", "What approach was chosen?")

Subagents

Ask your agent to "use subagents to ..." whenever you know you have a context-hungry task ahead that you would like to run isolated from the main context window.

When your agent is working on something and you suddenly got a question, use /btw to ask it. Of course, you can even ask multiple questions in parallel. The /btw subagent is ephemeral like tool subagents, but unlike tool subagents it sees the full contxt of your session (besides the fact that it can also use tools to read files).

Permissions

The permissions extension enforces Amp-style bash command permissions automatically. Use the /permissions command to toggle modes:

/permissions    # toggles between enabled and yolo

• enabled (default): Amp permission rules from ~/.config/amp/settings.json are enforced
• yolo: All bash commands are allowed without any checks; YOLO mode shown in status bar

The selected mode is persisted in ~/.pi/agent/amplike.json and restored on the next pi invocation.

Prompt Modes

/mode              # mode picker
/mode configure    # open mode configuration UI
/mode <name>       # switch directly
/mode store <name> # store current model+thinking into a mode

Notes:

• The extension bootstraps with default modes are rush, smart, and deep; they somewhat mirror Amp defaults.
• Modes config is loaded from .pi/modes.json (project), falling back to ~/.pi/agent/modes.json (global).
• Deleting all modes or setting "modes": {} in your modes file disables mode overlay behavior (shortcuts + editor mode border), while keeping /mode config UI available.

Components

Component	Type	Description
amp-skills	Extension	Adds Amp-compatible skill discovery paths (~/.config/agents/skills, ~/.config/amp/skills, .agents/skills)
permissions	Extension	Reads amp.commands.allowlist and amp.permissions from ~/.config/amp/settings.json (and .agents/settings.json) and intercepts bash tool calls accordingly; /permissions toggles between enabled and yolo (all commands allowed, status bar indicator, persisted in ~/.pi/agent/amplike.json)
handoff	Extension	/handoff [-mode <name>] [-model <provider/id>] <goal> command + handoff tool (with mode/model params) for AI-powered context transfer
modes	Extension	Prompt mode manager with model/thinking/color presets, editor border overlay, and shortcuts
session-query	Extension	session_query tool for querying parent sessions; uses the queried session's own model for analysis
session-query	Skill	Instructions for using the session_query tool
web-search	Skill	Web search via Jina API
visit-webpage	Skill	Webpage content extraction

Why "AmpCode-like"?

Amp Code has excellent session management built-in - you can branch conversations, reference parent context, and navigate session history. This package brings similar workflows to Pi:

• Context handoff → Amp's conversation branching
• Session querying → Amp's ability to reference parent context

Web Skills Origin

The web-search and visit-webpage skills were extracted from pasky/muaddib. The original implementations have additional features (rate limiting, multiple backends, async execution) that aren't needed for Pi's skill system.
