Acode AI Agent

A coding agent that runs inside Acode as an editor tab. It can read the open project, search files, propose edits, search the web, and — on Terminal-backed workspaces — run shell commands. You bring your own model provider.

Built on Pi

This is not a from-scratch agent. The model loop, providers, sessions, skills, compaction, and tool calling come from Pi (@earendil-works/pi-agent-core and @earendil-works/pi-ai 0.83.0). This plugin is the Acode/Android host: editor UI, workspace sandbox, approvals, and anything that has to work in a WebView without Node.

If you already use Pi on a desktop, the same ideas apply here:

• Providers, models, thinking levels, and device-code / API-key login
• Session trees, compaction, steer / follow-up queues, fork, clone, /tree
• Skills and prompt templates (.pi/skills, .agents/skills, /skill:name, load_skill)
• Project instructions from AGENTS.md
• Import / export of Pi JSON and JSONL sessions

What Pi’s desktop CLI does with a real terminal, cwd, and Node is adapted for Acode: files go through fsOperation (local, SAF, FTP, SFTP), bash exists only on Terminal-backed folders, and OAuth uses device codes instead of a localhost callback. Pi packages, tmux, and the Pi TUI are not part of this plugin.

Requirements

• Acode with version code 1002 or newer
• An open project folder (local, SAF, FTP, or SFTP)
• An API key or subscription from a supported provider

The plugin does not run a cloud backend. Inference happens through the provider you connect. There is no Node.js, daemon, or localhost callback server.

Install

From the Acode plugin store

1. Open Settings → Plugins.
2. Search for Acode AI Agent.
3. Install, then enable the plugin.

From a zip

1. Build plugin.zip with npm run build, or download a release zip.
2. Open Settings → Plugins → + → LOCAL and pick the zip.

Get started

1. Open a project folder in Acode.
2. Open the agent from any of:
   • the AI Agent sidebar app
   • command palette → AI Agent: Open
   • plugin settings → Open AI Agent
3. Tap the overflow menu and add a provider credential.
4. Ask it to inspect the project, edit a file, or review the open buffer.

The agent needs a folder. Without one, tools have no sandbox.

Commands registered with Acode

Command	What it does
AI Agent: Open	Opens the agent tab
AI Agent: New conversation	Starts a new session in the current folder
AI Agent: New Random project	Creates a starter project under Home and opens it

Sessions are stored per project. The sidebar lists them, can search them, and can open a session in a dedicated tab.

Providers

Pick a provider in Provider access. Keys and OAuth tokens go into Acode plugin-scoped secure storage, not settings JSON, session history, or tool results.

API key

OpenRouter, OpenAI, Anthropic, Google Gemini, xAI, Groq, DeepSeek, Cerebras, Fireworks, Together, Moonshot / Kimi, MiniMax, Z.AI, Kimi Coding, Qwen Token Plan, Ant Ling, Xiaomi.

Subscription / device-code sign-in

Provider	Sign-in
OpenRouter	OpenRouter account
Codex	ChatGPT Plus / Pro
Anthropic	Claude Pro / Max
GitHub Copilot	Copilot subscription
xAI	Grok / X subscription
Kimi Coding	Kimi Code

What it can do

Workspace tools (always available in an open folder)

• read_file — text or images (jpg, png, gif, webp, bmp); dirty editor buffers are the source of truth
• list_dir, grep, glob
• write_file and exact edit_file

Web

• web_search — live search (provider search when available, otherwise the device browser)
• fetch_content — public http(s) pages as markdown; GitHub blob URLs are rewritten to raw files; local/private hosts are blocked

On Acode Terminal workspaces only

• bash — streaming command with timeout and cancel, cwd already set to the terminal project
• Not registered for ordinary SAF, local-storage, FTP, or SFTP folders, because Alpine cannot address those Acode paths

Session extras

• todo_write — compact checklist for multi-step work
• ask_user_question — structured choices instead of guessing
• load_skill — load a discovered skill into context

Completed edit_file / write_file calls show a CodeMirror diff card in the work log. That is a per-tool preview, not a session-wide review tray.

Permissions

Three modes, from the composer:

Mode	Behavior
Ask	Approve each edit and each terminal command
Allow edits	Workspace writes this session; still ask for bash
Full access	Skip those prompts

Approvals can also be granted for the rest of the session from the prompt itself (Allow for session). Session grants reset on a new/forked/cloned session.

Composer

• Type / for slash commands, @ for workspace file mentions
• Attach images or files from the device
• Large pastes collapse into chips
• Send steers the current run; queue a follow-up for after it finishes
• Hardware shortcuts: Ctrl/⌘ + Enter send/steer, Ctrl/⌘ + Shift + Enter queue follow-up
• On a phone, software Enter is a newline; the send button submits

The agent also sees the active file and, if enabled, the current selection.

Skills, prompts, and project instructions

Project instructions — if the folder contains AGENTS.md or .agents.md, that file is added to the system prompt (first 32 KB).

Skills are folders with a SKILL.md front matter of name (lowercase letters, digits, hyphens) and description. Discovered automatically from:

• .agents/skills/
• .pi/skills/

Prompt templates are markdown files in .agents/prompts/ or .pi/prompts/. They become slash commands.

Global skills can be added from Pi settings → Add global skills folder. Acode data storage .agents/skills and .pi/agent/skills are also scanned.

Project skills win when names collide with global ones. /reload refreshes the list. /skill:name runs a skill when skill commands are enabled.

Example skill:

---
name: review-pr
description: Review the current changes like a code reviewer.
---

Focus on bugs, missing tests, and API breakage. Do not rewrite style-only issues.

Slash commands

Command	Action
/model	Choose the model for this session
/settings	Open Pi settings
/login /logout	Provider credentials
/resume	Session list
/new	Fresh session
/compact	Summarize older context
/name	Rename this session
/session	Usage and identity
/tasks	Task list (clear, clear-completed)
/tree	Jump to an earlier point
/fork	Fork from a user message
/clone	Clone the active branch
/copy	Copy the latest assistant reply
/export	Show portable JSON (copy from the sheet)
/import	Import a Pi JSON / JSONL session
/reload	Reload skills and prompts
/hotkeys	Composer shortcuts

Project prompts and /skill:name are added to this list when they load.

Workspaces

The agent talks in workspace-relative POSIX paths. Device URIs, absolute paths, .., and credential-bearing remote URLs are rejected and never sent to the model.

Folder type	Files	bash
Local / Acode Terminal FS	yes	yes, if Executor is present
SAF content://	yes	no
FTP / SFTP	yes, bounded walks	no

Remote walks stay sequential and capped (default 200 files, lower on FTP/SFTP search).

Security

• Paths go through PathSandbox. Absolute paths, URI schemes, .., backslashes, and null bytes are rejected.
• Workspace URIs never appear in tool results or the transcript.
• Provider secrets use PluginContext.getSecret / setSecret. A host without that API keeps credentials in memory only.
• Writes are sequential and gated. Open files stay unsaved until you save them.
• fetch_content refuses localhost, private networks, and URLs with embedded credentials.
• Backgrounding the app aborts the current run.

Treat Full access as a real grant: the agent can write files and, on Terminal workspaces, run commands.

Extension API

Other Acode plugins can extend the agent after it initializes:

const runtime = acode.require("acode.ai.agent.runtime");

runtime.registerTool(myPiAgentTool);
runtime.registerProvider(myPiProvider);
runtime.registerContext("my-plugin:context", async () => "Extra project context");
runtime.registerFeature({
  id: "my-plugin:feature",
  label: "Feature",
  description: "Declared capability",
  available: ({ workspace }) => Boolean(workspace),
});
runtime.open();
runtime.selectProvider("openrouter");

• registerTool — Pi AgentTool. Tools registered after a session starts are applied immediately.
• registerProvider — Pi provider. Live sessions pick it up.
• registerContext — extra system-prompt text, rebuilt before every user turn.
• registerFeature — metadata only in 0.1.0; it is not shown in the UI yet.
• Never evaluate arbitrary project JavaScript in the WebView. Cross-plugin tools must come from another Acode plugin.

Unregister by calling the function returned from registerTool / registerContext / registerProvider.

Development

npm install
npm run typecheck
npm test
npm run build

npm run build typechecks, bundles a Chrome 90 / WebView IIFE, rejects Node runtime imports, enforces a 1.92 MB dist/main.js budget, and writes plugin.zip.

npm run dev

Serves and watches on port 3000 for plugin reload during development.

The runtime stays browser/WebView-compatible: no Node built-ins, child processes, IPC, or a real process cwd.
