N-Jet

AI coding agent sidebar for VS Code — connects to the N-Jet backend with repository awareness, self-validation, and streaming responses.

v0.3.0 moves N-Jet from "AI chat with code awareness" toward a coding agent that verifies its own work.

Features

• Activity bar N-Jet icon with sidebar webview (React)
• Auto-connect on startup when a token is stored in SecretStorage
• Status bar indicator: Connecting, Connected, Reconnecting, Authentication failed, Offline
• Progressive diagnostics: Connecting → Checking server → Validating account → Connected as [email protected]
• N-Jet: Login opens browser sign-in at https://www.n-jetai.com/njet/vscode-connect (no token paste required)
• Browser handoff uses your existing n-jetai.com Supabase session and returns vscode://n-jetcoder.njet/auth?token=...
• Token fallback: N-Jet: Login with API Token (only when browser sign-in is unavailable)
• Workspace header: project name, git branch, workspace path, indexed file count
• Repository intelligence: framework, language, package manager, build system, database detection
• Persistent local index + cross-session workspace memory for symbol lookups
• Incremental re-index on file save; N-Jet: Reindex Repository command
• Multi-file planning for large feature requests before streaming a response
• Self-validation loop: after edits, runs npm run build, lint, typecheck, and test (when present); auto-fixes failures up to 3 retries
• Diff preview: side-by-side old/new diffs via vscode.diff; Accept all / Reject / Accept selected files
• Agent confidence: Low / Medium / High score before applying edits (context coverage + validation history)
• Symbol graph: import/export, API routes, and database model edges for cross-file reasoning
• Context efficiency: caps symbols, file excerpts, and graph neighbors to keep prompts small
• Error-aware coding: parses build/lint/type errors and streams fixes without asking for pasted logs
• Agent file editing: parses njet-edit blocks and applies workspace changes with confirmation
• Preview integration: N-Jet: Open Preview + detected Vite/Next/Node dev URLs in context
• Model modes: Fast / Balanced / Deep (composer selector + njet.modelMode setting)
• Session restore across extension reloads (chat history + account)
• Health check (GET /api/v1/health) and auth validation (GET /api/v1/me)
• Auto-reconnect on network loss, backend restart, and extension reload
• Debug logging: [NJET_EXTENSION_*], [NJET_INDEX], [NJET_VALIDATE], [NJET_EDIT], [NJET_PLAN]
• Secure token storage via VS Code SecretStorage
• N-Jet: Login command for API token entry
• Streaming chat via POST /api/v1/chat (SSE)

Agent workflow (v0.3.0)

1. User request → repository index + symbol graph + compact context injected
2. Multi-file plan streamed with assistant response
3. njet-edit blocks parsed → diff preview with confidence badge
4. User accepts (all or selected files) → edits applied
5. Validation suite runs → failures summarized → auto-fix stream (max 3 retries)
6. Success or final failure surfaced in sidebar + Output channel
