# Extensions Extensions are TypeScript modules that add executable behavior to Pi. Use one when a workflow needs tools, commands, event handlers, model providers, session state, or terminal UI rather than instructions alone. An extension runs inside the Pi process with the same operating-system permissions. It can inspect prompts, tool calls, files, credentials, and session history, so load extensions only from sources you trust. Typical extensions add an agent tool, protect paths, confirm dangerous commands, react to session events, modify context, expose a command, or display persistent status. <a id="quick-start"></a> <a id="writing-an-extension"></a> <a id="create-an-extension"></a> ## Create and load an extension An extension exports a default factory that receives `ExtensionAPI`. The factory registers capabilities for the current extension runtime. Create `~/.pi/agent/extensions/hello.ts`: ```typescript import type { ExtensionAPI } from "@earendil-works/pi-coding-agent"; export default function (pi: ExtensionAPI) { pi.registerCommand("hello", { description: "Show a greeting", handler: async (name, ctx) => { ctx.ui.notify(`Hello, ${name || "world"}!`, "info"); }, }); } ``` Start Pi and run `/hello`. During development, load a file directly: ```bash pi --extension ./hello.ts ``` Pi uses `jiti`, so local TypeScript extensions do not need a separate compilation step. Use [Pi packages](packages.md) for distributed extensions and dependencies. <a id="extension-locations"></a> <a id="available-imports"></a> <a id="choose-where-it-loads"></a> ## Add it to Pi Place the extension in your user or project extensions directory. Pi loads direct TypeScript or JavaScript files and subdirectories containing an `index.ts` or `index.js` entry point. Use a single file for a small extension and a directory for a multi-file implementation. Put npm dependencies in a nearby `package.json`. See [Configuration](configuration.md) for conventional locations and [Settings](settings.md#resources) for additional paths. Reload replaces the extension runtime, so code after `await ctx.reload()` must not reuse state from the old runtime. Only personal and explicit command-line extensions can participate in the `project_trust` event that runs before project extensions load. <a id="understand-the-lifecycle"></a> ## Respect the runtime lifecycle The factory can be synchronous or asynchronous. Pi waits for an asynchronous factory before startup continues, allowing it to fetch configuration or register providers needed during startup. Do not start processes, sockets, watchers, or timers in the factory because some invocations load extensions without starting a session. Start long-lived resources from `session_start` or from the command or tool that needs them. Close session-scoped resources from an idempotent `session_shutdown` handler. A run proceeds from input and `before_agent_start`, through model, message, and tool events, to `agent_end`. Automatic retries, recovery, compaction, or queued work can continue afterward. <a id="agent_start--agent_end--agent_before_settle--agent_settled"></a> `agent_before_settle` is the final actionable boundary: it can append entries and request one continuation. `agent_settled` is final and notification-only; use it when an integration needs to know Pi will not continue automatically. <a id="extensionapi-methods"></a> ## Choose an integration point | Capability | Main API | |---|---| | Observe or modify lifecycle behavior | `pi.on()` | | Add a model-callable operation | `pi.registerTool()` | | Add a `/` command | `pi.registerCommand()` | | Add a shortcut or CLI flag | `pi.registerShortcut()` or `pi.registerFlag()` | | Send user or custom messages | `pi.sendUserMessage()` or `pi.sendMessage()` | | Persist non-context session data | `pi.appendEntry()` | | Change active tools, model, or thinking level | Session control methods on `pi` | | Add a model provider | `pi.registerProvider()` | | Add terminal rendering | Renderer registration and `ctx.ui` | | Communicate with another extension | `pi.events` | Use the exported declarations in [`extensions/types.ts`](https://github.com/earendil-works/pi/blob/main/packages/coding-agent/src/core/extensions/types.ts) for exact event, context, tool, and result types. ## Follow the extension contracts <a id="events"></a> <a id="work-with-events"></a> ### Events and concurrency Handlers run in extension load and registration order. `pi.on()` returns a function that unsubscribes that registration; changes do not affect a dispatch already in progress. Some events notify; others transform data, replace results, or cancel an operation. Use each event’s declared result type rather than assuming every return value has an effect. Events cover resource discovery, sessions, agent and message lifecycle, providers, tools, and raw input. `before_agent_start` exposes both the current prompt and its structured `systemPromptOptions`. Prefer changing prompt sections, selected tools, or guidelines so Pi can append a transcript delta. Returning `systemPrompt`, or setting `forceSystemPrompt`, replaces the whole prompt for that run while the transcript continues recording the structured sections. Providers receive the forced text as their leading system prompt. `message_end` can replace a finalized message while preserving its role. `tool_call` can mutate input or block execution. `tool_result` handlers compose, with each handler seeing prior changes. <a id="context_with_system"></a> `context` transforms conversation messages without prompt and tool system messages; Pi restores that state afterward. Use `context_with_system` only when a request-local transformation must own the complete transcript, and keep a system message at index zero. `turn_end` and `agent_before_settle` are actionable boundaries. Their handlers can chain proposed `custom`, `custom_message`, `context_edit`, or `compaction` entries and return `continue: true` for one next model request. Guard continuation conditions because an unconditional continuation can loop. Use the exported event declarations for the complete validation and ordering contract. <a id="cache_warming_decision"></a> `cache_warming_decision` can override an idle prompt-cache refresh with `{ action: "warm" }` or `{ action: "stop" }`. The last handler that returns an action wins. Tool calls from one assistant message can run in parallel. Do not assume a sibling call or result exists when another tool event runs. Use `ctx.signal` for nested work owned by an active turn; commands and idle session events often have no operation signal. A `user_bash` handler that returns `undefined` passes the command to the next handler and then to local execution if no handler handles it. Returning `operations` or `result` stops propagation. A handler failure blocks the command rather than falling through to local execution. <a id="custom-tools"></a> <a id="register-tools"></a> ### Tools A custom tool defines a name, model-facing description, TypeBox parameter schema, and `execute()` function. Its result requires model-facing `content` and a `details` field for rendering or state reconstruction. Use `details: undefined` when there are no structured details. If the tool makes nested model calls, include their `usage` in the result so session totals remain accurate. Throw from `execute()` to produce a failed tool result. Returning an object does not mark it as an error. Return `terminate: true` only when the agent should skip its automatic follow-up after every completed tool in that batch agrees to terminate. Use sequential execution when tools share mutable in-memory state. File-mutating tools should wrap the complete read-modify-write operation with `withFileMutationQueue()`. Truncate large model-facing results and tell the model where to read the complete output. See [`hello.ts`](../examples/extensions/hello.ts), [`todo.ts`](../examples/extensions/todo.ts), [`dynamic-tools.ts`](../examples/extensions/dynamic-tools.ts), and [`truncated-tool.ts`](../examples/extensions/truncated-tool.ts). ### Activate tools dynamically Register every tool first, keep optional tools inactive, and use `pi.setActiveTools()` from a loader tool to select the desired active tools. Names must already be registered; unknown names are ignored. Pi records the initial prompt and tool set in the transcript's first system message, then appends tool and prompt changes before the next model request. Providers that cannot represent the transition receive a complete transcript checkpoint, which can invalidate the cached prefix. <a id="extensioncontext"></a> <a id="extensioncommandcontext"></a> <a id="use-extension-context"></a> ### Context and session changes `ExtensionContext` provides the working directory, mode, UI, session manager, model runtime, abort signal, context usage, and controls for compaction and shutdown. Use `ctx.modelRegistry.streamSimple()` for provider-neutral nested model calls. Command handlers receive `ExtensionCommandContext`, which adds operations for waiting until idle, reloading, tree navigation, and session replacement. These operations are command-only because calling them from lifecycle handlers can deadlock the runtime. Session replacement invalidates the old context. Capture only plain data before switching, then use the fresh context supplied to `withSession` for session-bound work. <a id="state-management"></a> <a id="persist-state"></a> ### State Choose storage based on how state participates in the conversation: | State | Storage | |---|---| | Tool state that follows the active branch | Tool-result `details` | | Durable data excluded from model context | `pi.appendEntry()` | | Custom content stored and sent to the model | `pi.sendMessage()` | | Data outside one session | External storage | Reconstruct branch-sensitive state from `ctx.sessionManager.getBranch()` during `session_start`. Do not rebuild it from every file entry because abandoned branches represent alternative histories. Register an entry or message renderer when custom stored content should appear in the transcript. <a id="custom-ui"></a> <a id="mode-behavior"></a> <a id="interact-with-the-user"></a> <a id="account-for-each-mode"></a> ### UI and modes `ctx.ui` provides dialogs, notifications, status text, widgets, titles, editor access, and custom components. Use `ctx.ui.custom()` only when the interaction needs its own rendering and input. See [Terminal UI](tui.md) for component, focus, overlay, theme, and performance guidance. Extensions load in interactive, RPC, JSON, and print modes. Interactive mode provides the complete terminal UI. RPC can forward supported dialogs and notifications through the [RPC Extension UI protocol](rpc-extension-ui.md), but not custom terminal components; JSON and print modes have no UI. Guard terminal-only behavior with `ctx.mode === "tui"` and use `ctx.hasUI` for interactions supported by interactive and RPC clients. Keep tool and event behavior independent from rendering so non-interactive modes remain functional. <a id="error-handling"></a> <a id="handle-errors-and-shutdown"></a> ### Errors and cleanup Pi reports handler errors and continues where possible. A `tool_call` handler failure blocks the tool as a fail-safe; a tool execution failure becomes an error result for the model. Release resources in `session_shutdown` even when normal operation attempted cleanup. Keep cleanup idempotent because cancellation, reload, session replacement, and process exit can converge on the same path. Use `ctx.shutdown()` to request an orderly process shutdown. <a id="examples-reference"></a> <a id="use-examples-as-the-implementation-reference"></a> ## Examples and reference The checked [extension examples](../examples/extensions/) cover tools, lifecycle events, commands, flags, shortcuts, state, rendering, providers, OAuth, remote execution, and terminal components. Start with the smallest example matching your integration point. Use [Custom Providers](custom-provider.md) for model-service integrations, [Terminal UI](tui.md) for custom components, and [Pi Packages](packages.md) to install or distribute extensions with other resources.

# SDK `@earendil-works/pi-coding-agent` embeds Pi in a Node.js or Bun process. It provides direct TypeScript access to the agent, sessions, tools, models, and resources used by the command-line application. Use the SDK for in-process TypeScript integration. For a language-independent or isolated subprocess, see [CLI Integration](cli-integration.md). ```typescript import { createAgentSession } from "@earendil-works/pi-coding-agent"; const { session } = await createAgentSession(); try { await session.prompt("What files are in the current directory?"); console.log(session.getLastAssistantText()); } finally { session.dispose(); } ``` This uses the working directory, discovered resources, stored settings, and configured credentials. `prompt()` resolves when the run finishes. The [complete minimal example](../examples/sdk/01-minimal.ts) also streams text events. All [SDK examples](../examples/sdk/) are typechecked with the repository. <a id="session-management"></a> ## Session lifecycle `createAgentSession()` creates an `AgentSession`. The session owns one conversation, its model and tools, queued messages, compaction state, and extension runtime. Read current state through `session.messages`, `session.model`, `session.thinkingLevel`, `session.systemPrompt`, and `session.getActiveToolNames()`. `session.systemPrompt` is read-only and returns the current effective system prompt, including changes that have not yet been sent to the model. Tool changes are declared to the model before the next request. <a id="sessionmanager-api"></a> ### Session storage Sessions are persistent by default. `SessionManager` owns the persisted or in-memory entry tree and tracks its active leaf. Branching changes that leaf without deleting abandoned branches. When Pi reconstructs model context, the manager selects the active branch and applies compaction. `SessionManager` is authoritative for finalized model context. Restore external history by constructing the session with a manager containing those entries. Assigning `session.agent.state.messages` does not replace persisted context. Use an in-memory manager when the host does not want session files: ```typescript import { createAgentSession, SessionManager } from "@earendil-works/pi-coding-agent"; const { session } = await createAgentSession({ sessionManager: SessionManager.inMemory(), }); ``` See the checked [sessions example](../examples/sdk/11-sessions.ts) for creating, opening, continuing, listing, and forking sessions. [Session File Format](session-format.md) defines the persisted JSONL contract, and [Message Types](message-types.md) defines transcript values. For exact methods and signatures, use the exported TypeScript declarations or [`session-manager.ts`](../src/core/session-manager.ts). `cwd` selects the workspace used for project resource discovery, context files, session grouping, and built-in tool paths. Pass it explicitly when the target differs from `process.cwd()`. `session.dispose()` aborts active work, invalidates extension contexts, disconnects from the agent, and removes event listeners. Call it when the session is no longer needed. `AgentSessionRuntime` adds `newSession()`, `switchSession()`, `fork()`, and `importFromJsonl()`. Each operation replaces the active `AgentSession` and recreates services for the target working directory. After a runtime replacement, subscriptions belong to the old `AgentSession` and must be rebound. See the [session runtime example](../examples/sdk/13-session-runtime.ts). ## Prompting `prompt()` handles extension commands and expands file-based prompt templates before ordinary user messages enter the agent. For an accepted agent run, it resolves after the run finishes, including automatic retries. A prompt sent while the session is already streaming must specify whether it should steer the current run or follow it. Calling `prompt()` without that choice rejects rather than guessing. A steering message enters after the current assistant turn and its tool calls. A follow-up enters after the current run finishes its pending work. `steer()` and `followUp()` expose those behaviors directly. `abort()` stops the active operation and waits for the session to become idle. `waitForIdle()` waits without aborting it. ## Subscribing to events Subscribe before prompting when the host needs streamed output: ```typescript const unsubscribe = session.subscribe((event) => { if (event.type === "message_update" && event.assistantMessageEvent.type === "text_delta") { process.stdout.write(event.assistantMessageEvent.delta); } }); try { await session.prompt("Explain this repository"); } finally { unsubscribe(); } ``` Session events report message updates, tool execution, queues, compaction, retries, and run lifecycle changes. `message_end` contains the authoritative completed message. `agent_end` marks the end of one low-level agent run, but automatic recovery or queued work can still follow. Use `agent_settled` when the host needs to know that Pi will not continue automatically. ## Configuring a session Without overrides, the factory creates a `ModelRuntime`, file-backed `SettingsManager`, persistent `SessionManager`, `DefaultResourceLoader`, and the configured default tools. Each boundary can be supplied explicitly: - `modelRuntime`, `model`, `thinkingLevel`, and `scopedModels` control model access and selection. - `settingsManager` supplies merged settings or an in-memory configuration. - `sessionManager` supplies persistent or in-memory conversation history. - `resourceLoader` supplies extensions, skills, prompt templates, themes, and context files. - `tools`, `noTools`, `excludeTools`, and `customTools` control the active tool set. Use `DefaultResourceLoader` when you want standard discovery with selected overrides. Supply a custom `ResourceLoader` when the host owns resource storage and discovery completely. <a id="inlineextension"></a> Inline extension factories can be supplied through `DefaultResourceLoader`. Give one an `InlineExtension` name only when it needs a stable name in diagnostics and startup output. See the focused examples for [models](../examples/sdk/02-custom-model.ts), [tools](../examples/sdk/05-tools.ts), [extensions](../examples/sdk/06-extensions.ts), and [full control](../examples/sdk/12-full-control.ts). ## Examples | Example | Purpose | |---|---| | [Minimal](../examples/sdk/01-minimal.ts) | Create, prompt, observe, and dispose a session | | [Custom model](../examples/sdk/02-custom-model.ts) | Select a model and thinking level | | [System prompt](../examples/sdk/03-custom-prompt.ts) | Replace or append to the system prompt | | [Skills](../examples/sdk/04-skills.ts) | Discover, filter, and add skills | | [Tools](../examples/sdk/05-tools.ts) | Select built-in tools and their working directory | | [Extensions](../examples/sdk/06-extensions.ts) | Load file-based and inline extensions | | [Context files](../examples/sdk/07-context-files.ts) | Add or replace project instructions | | [Prompt templates](../examples/sdk/08-prompt-templates.ts) | Add file-style prompt templates | | [Credentials](../examples/sdk/09-api-keys-and-oauth.ts) | Configure credential and model storage | | [Settings](../examples/sdk/10-settings.ts) | Supply file-backed or in-memory settings | | [Sessions](../examples/sdk/11-sessions.ts) | Control session persistence and restoration | | [Full control](../examples/sdk/12-full-control.ts) | Replace default discovery and state services | | [Session runtime](../examples/sdk/13-session-runtime.ts) | Replace the active session safely | <a id="exports"></a> ## Resources - [Choose a Model](models.md) covers model selection and compatible endpoints; [Provider Authentication](providers.md) covers credentials and cloud-provider setup. - [Configuration](configuration.md) explains normal discovery and settings; [Settings](settings.md) lists every setting. - [Sessions and Context](sessions.md) explains session behavior; [Session Format](session-format.md) defines persisted entries; [Message Types](message-types.md) defines shared transcript values. - [Extensions](extensions.md), [Skills](skills.md), and [Prompt Templates](prompt-templates.md) document resources supplied through a `ResourceLoader`. - [CLI Integration](cli-integration.md) covers print, JSON, and RPC alternatives to an in-process SDK integration.
