Intent
Describe a feature. Agents build, verify, and ship it — in parallel.

Intent, from Augment Code, reimagines the coding agent as an orchestrated team rather than a single assistant. You write a feature spec in plain language. A Coordinator Agent breaks it into tasks. Specialist Agents execute those tasks in parallel inside isolated git worktrees. A Verifier Agent checks results against your original spec before surfacing anything for your review. The spec is "living" — it updates as work progresses, and when requirements change, updates propagate to all active agents. This is meaningfully different from one-shot prompting or even multi-step agentic coding. Intent is designed for enterprise teams working on large codebases where a single feature might touch dozens of files across multiple services. The built-in Chrome browser lets agents preview local changes without leaving the workspace. It integrates with existing git workflows rather than replacing them. Launched in public beta February 2026 (macOS only, Windows on waitlist), Intent got its highest visibility yet when it hit Product Hunt with 302 votes this week. Augment Code has been quietly building toward this: their previous focus on large-enterprise codebase indexing gives Intent's retrieval layer an advantage over agents starting from scratch.

Self-hosted enterprise AI client from Mozilla — no cloud required

Thunderbolt is an open-source enterprise AI client built by MZLA Technologies, the Mozilla Foundation subsidiary behind Thunderbird. It gives organizations a private, self-hostable frontend for AI that supports Chat, Search, Research, and Tasks workflows — routing all inference through a backend proxy the org controls. Think Microsoft Copilot or Google Workspace AI, but one where your data never leaves your servers. Under the hood, Thunderbolt acts as a model-agnostic gateway. Admins can wire it to Anthropic, OpenAI, Mistral, or local Ollama instances from a single config file. The v0.1 release ships MCP (Model Context Protocol) support in preview and OIDC for enterprise identity providers, which is a meaningful differentiator for regulated industries. Why does this matter? Most enterprise AI tools still require cloud data egress, creating compliance headaches for finance, healthcare, and government. Mozilla's brand trust + open-source auditability + Thunderbird's install base (~25M users) gives Thunderbolt a credible distribution path that most scrappy AI startups can only dream about. Keep an eye on the MCP integrations as those mature.
Reviewer scorecard
“The parallel worktree approach is genuinely smart — agents don't step on each other, and the living spec means you're not herding a single agent through a long task linearly. For features that touch multiple modules, this could cut agent coding time dramatically. macOS-only is a real limitation though.”
“The OIDC support and multi-backend inference proxy out of the box are genuinely useful. Most open-source AI frontends make you roll your own auth from scratch. Mozilla's Thunderbird team knows enterprise distribution — this isn't some weekend project that'll be abandoned in a month.”
“Multi-agent coordination sounds great until the Verifier Agent approves something the Specialist Agents hallucinated together. Coordinated AI errors are harder to catch than single-agent errors because they have the veneer of consensus. I'd want to see extensive user testing on real enterprise codebases before trusting this in production.”
“It's v0.1 and MCP support is labeled 'preview,' which means it's probably buggy. The real question is whether organizations trust Mozilla — a company that's struggled to monetize Firefox — to own their critical AI infrastructure. Adoption will be slow in regulated industries without a real support contract.”
“Intent is the most concrete vision I've seen of what software development looks like when the unit of work is a feature spec, not a file edit. The living spec abstraction — where truth lives in intent, not implementation — will age well. This is the direction the whole industry is heading.”
“Enterprise AI is currently a duopoly race between Microsoft and Google. An open-source, self-hostable alternative with Mozilla's brand sits in a completely uncontested lane. If MCP matures into a real standard, Thunderbolt becomes the neutral hub for private AI — potentially more important than the LLMs it proxies.”
“The built-in browser for previewing changes without leaving the workspace is a small detail that shows good UX thinking. For product builders who move between design specs and implementation, having a feature spec drive coordinated agent work — and seeing a live preview — is exactly the kind of tight loop that makes creative work faster.”
“Design shops and creative agencies working under NDAs finally have a legitimate option that doesn't route client briefs through OpenAI's servers. The Research and Tasks modes look like exactly what briefing and asset-management workflows need.”
