Gatishil AI

Agentic coding assistant for Visual Studio Code, powered by the Gatishil AI gateway.

Overview

Gatishil AI brings an autonomous, tool-calling coding agent directly into the VS Code sidebar. It connects to the Gatishil AI gateway's OpenAI-compatible /v1/chat/completions API and drives an agent loop that can read files, list directories, write files, and run shell commands within your workspace — with every mutating action gated behind explicit user approval.

Key capabilities:

• Agentic tool-calling loop — the assistant plans and executes multi-step tasks against an OpenAI-compatible chat completions API.
• Workspace-aware tools — read files, list directories, write files, and run shell commands, all scoped to your open workspace.
• Approval gate — file writes and shell commands require explicit confirmation before they run, so nothing changes your project without consent.
• Native chat experience — a React-based chat interface integrated into the VS Code activity bar.

Architecture

┌──────────────┐  postMessage   ┌────────────────────┐  fetch /v1/chat  ┌─────────────┐
│ Webview (UI) │ ◀────────────▶ │ Extension host     │ ───────────────▶ │  Gateway    │
│ React + Vite │                │ agent loop + tools │ ◀─────────────── │ (tool_calls)│
└──────────────┘                └────────────────────┘                  └─────────────┘

• src/agent.ts — the loop: call the gateway, run the tools it asks for, feed results back, repeat until done.
• src/tools.ts — tool schemas + executors (read_file, list_dir, write_file, run_command).
• src/chatView.ts — the sidebar webview provider; bridges UI messages ↔ the agent, holds conversation + approvals.
• webview/ — the React chat UI.

Develop

npm install
npm run build        # bundles the extension (esbuild) + webview (vite) into dist/

Then press F5 in VS Code to launch an Extension Development Host. Open the Gatishil AI icon in the activity bar.

• npm run watch — rebuild the extension host on change (re-run vite build for webview changes).
• npm run package — produce a .vsix (requires dist/ built first).

Configure

• Run “Gatishil AI: Set API Key” from the command palette (stored in SecretStorage, never in settings).
• Settings (gatishil.*): baseUrl, model, maxTokens, maxSteps, autoApprove, allowInsecure.

allowInsecure defaults to true so the IP-based dev gateway's self-signed TLS cert is accepted. Turn it off once the gateway has a valid certificate.

Status

First working skeleton: non-streamed agent turns, four core tools, approval gate on writes/commands. Next: streamed token output, a diff view for write_file, and file-mention (@path) context.
