Pi Customization
Pi coding agent customization — Themes, Keybindings, Prompt Templates, System Prompt overrides, and Settings. Use when configuring or modifying the visual appearance, UI colors, keyboard shortcuts, prompt templates, or the default system prompt behavior of the pi terminal agent. Use for "custom theme pi", "change keybindings", "modify system prompt", "SYSTEM.md", "APPEND_SYSTEM.md", "settings.jso…
Pi Rpc Sdk
Pi headless RPC JSONL over stdin/stdout, strict LF framing, --mode json event streaming, and Node SDK alternatives (AgentSession). Use when integrating pi --mode rpc, pi --mode json, writing a client that speaks the protocol, reading JSON event streams, or choosing RPC vs in-process SDK. Use for "pi rpc client", "JSONL framing", "readline rpc", "--mode json", "json events", "embed pi without subp…
Plan Review Gate
Use after saving a non-trivial plan or decision RFC when a fail-closed feasibility, completeness, and alignment review must block execution.

Pi Tui
@mariozechner/pi-tui — Minimal terminal UI framework with differential rendering, CSI 2026 synchronized output, and Component interfaces. Use when building or debugging terminal interfaces, TUI components, Editor, Markdown, SelectList, or handling input and ANSI widths. Use for "differential rendering", "matchesKey", "Focusable IME", even if pi-coding-agent is not mentioned.
Pi Cli Workspace
Pi terminal agent workspace — install, /commands, sessions, compaction, settings.json, AGENTS.md, skill discovery, precedence, session JSONL, /tree, providers/auth, models.json, credential resolution, platform setup, editor (@file, Tab, images, !bash), message queue (steering, follow-up), built-in tools (read/bash/edit/write/grep/find/ls, --tools, --no-tools), print mode (-p, piped stdin), SYSTEM…
Pi Web Ui
@mariozechner/pi-web-ui — Lit web components for chat UIs, ChatPanel, IndexedDB storage stores, artifacts, tools shipped with web-ui. Use when embedding Pi AI/agent in a browser app or debugging web-ui storage, ChatPanel setup, or example app. Use for "pi web chat component", "ChatPanel", "IndexedDBStorageBackend", even if pi-coding-agent CLI is unrelated.

Pi Agent Embedding
@mariozechner/pi-agent-core Agent runtime — message flow, tool execution modes, event sequence for prompt() and continue(), embedding in apps. Use when building on Agent class, wiring subscribers, or debugging tool loops beside pi-ai. Use for "pi agent events", "beforeToolCall", "agent.subscribe", even if coding-agent CLI is not involved.
Mcp Cli
Use when you need a one-off MCP server capability during research or debugging without permanently mounting it as a context-polluting integration.
Pi Mom
@mariozechner/pi-mom — Slack bot Master Of Mischief (Mom), self-managing agent, Docker sandbox, and events system. Use when setting up Mom in Slack, debugging data/ workspace issues, managing context.jsonl/log.jsonl memory, or creating periodic/immediate events. Use for "mom slack bot", "docker sandbox", "mom events", "artifacts server", "cloudflare tunnel", "custom tools", "MomCustomTool", "mult…
Code Review
Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/PRD asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to…
Setup Matt Pocock Skills
Configure this repo for the engineering skills — set up its issue tracker, triage label vocabulary, and domain doc layout. Run once before first use of the other engineering skills.
Memory Compounding
Review and sharpen persistent memory so it compounds instead of accumulating. Use when pruning pi-hermes-memory entries, doing monthly memory hygiene, or when the same lesson has been recorded multiple times.
Verification Before Completion
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
Codebase Hygiene
Find semantic duplicates (same intent, different implementation) and shallow modules (thin wrappers spreading complexity). Read-only advisory — changes route through BUILD with full gates. Use when auditing code quality, before refactoring, or when a codebase feels bloated.
Receiving Code Review
Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
Brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Setup Maintenance
Maintain and improve a Pi coding agent setup over time — prevent drift AND find new leverage. Use when auditing setup health, before adding a package/extension, before publishing, or when asked "is my setup healthy" / "audit my setup" / "how do I keep this sharp".
Diagnosing Bugs
Diagnosis loop for hard bugs and performance regressions. Use when the user says "diagnose"/"debug this", or reports something broken/throwing/failing/slow.
Diff Driven Docs
Treat documentation as a first-class deliverable of every BUILD phase. Classify the diff's doc impact across 3 layers (business/technical/audit) and write only the updates genuinely needed. Use after BUILD completes, before a commit/PR, or when asked "are docs up to date".
Pi Extension Authoring
Authoring Pi TypeScript extensions — ExtensionAPI, custom tools, commands, UI hooks, resources_discover, `registerProvider()`, and how extendResources merges skill paths after base reload. Use when the user builds or debugs pi extensions, registers tools, adds /commands, hooks events, integrates TUI components, or ships extension examples. Use for "how do I extend pi", "extension API", "registerT…
Pi Pods
@mariozechner/pi — Deploy and manage vLLM LLM GPU pods, DataCrunch/RunPod setup, and CLI agent interface. Use when spinning up GPU instances, configuring vLLM, managing tensor parallelism, or interacting with models via pi agent. Use for "pi pods setup", "vLLM memory", "Qwen GLM models pi", even without naming the pods package.
Pi Ai Library
@mariozechner/pi-ai — unified LLM streaming API, tools, providers, thinking events, and cross-provider handoffs as implemented in pi-mono. Use when integrating or debugging pi-ai, adding providers, using stream/complete, TypeBox tools, or token usage. Use for "pi-ai stream", "getModel", "new provider in pi", even if the user only says OpenRouter or Anthropic APIs.
Pi Package Authoring
Pi packages — npm/git distribution of extensions, skills, prompts, themes via keywords pi-package and package.json pi manifest; pi install paths and security expectations. Use when shipping or consuming pi-package, adding pi.skills entries, or explaining install vs project-local -l. Use for "publish pi skills on npm", "pi install", "pi-package.json", even without naming this skill.
