Before writing a single line, MAESTRO runs an adversarial debate between two frontier models — each reading your actual files, challenging every assumption, and grounding every decision in evidence. Nothing executes until you approve the spec. Nothing commits until it passes every quality gate.
OpenAI GPT-5.4 proposes. Claude Sonnet 4.6 challenges. Each reads your actual codebase — imports, call graphs, architecture — and disputes every claim that isn't grounded in evidence. The spec that reaches execution has survived an adversarial process no single model can replicate.
MAESTRO builds a live structural graph of your codebase using Tree-sitter AST parsing. Semantic search runs HyDE — generating hypothetical code snippets to bridge the vocabulary gap between intent and implementation. Episodic memory records every past mission on your project: what failed, why, and what was learned. Every mission makes the next one smarter.
After debate, MAESTRO produces a specification: exact files, constraints, test expectations, confidence score, risk level. You read it. You approve it. Only then does execution begin. Not a suggestion — a contract between you and the agent.
Every mission runs inside an isolated Firecracker microVM. Seven deterministic safety checks run before review. A five-dimension structured review scores the output before commit. If anything fails, targeted revision is triggered with exact instructions — not a retry from scratch.
Branch snapshot, full file inventory, language detection. MAESTRO knows exactly what it is touching before it starts.
AST-derived structural graph queries (Memgraph), HyDE-enhanced semantic search (FAISS), web research via Exa, and episodic memory from every past mission on this project. MAESTRO understands your architecture before the debate begins.
GPT-5.4 proposes. Claude Sonnet 4.6 reads your files and disputes every ungrounded claim. The spec that emerges has survived adversarial scrutiny.
Exact files to modify, constraints, test expectations, confidence score, risk level. You read it. You approve it. Nothing happens without your sign-off.
Isolated Firecracker microVM. Claude multi-agent executor with parallel sub-agents for complex tasks. No access to your system during execution.
Seven deterministic checks: secrets scan, scope enforcement, import validation, shrink detection, destructive operations, protected files, threat model.
5-dimension scoring, severity gate, targeted revision
Clean diff committed, episode stored, codebase re-indexed
Every function, class, method, and import relationship in your codebase is indexed into a live knowledge graph using Tree-sitter AST parsing. MAESTRO queries this graph to find callers, dependencies, and impact chains before proposing any change.
Hypothetical Document Embedding bridges the gap between a developer's intent and implementation vocabulary. Instead of searching for "rate limiter" and hoping for a match, MAESTRO generates a hypothetical code snippet and searches by embedding similarity — finding what you mean, not just what you typed.
Every mission outcome is stored per project: what was attempted, what failed, what was learned. Before the next mission on your project, MAESTRO retrieves relevant past episodes and feeds them into the debate. The more you use MAESTRO on a project, the better it gets at that project specifically.
"Refactor the authentication service to replace JWT with rotating refresh tokens, update all 14 dependent endpoints, add Redis token blacklist, and maintain 100% test coverage."
"Migrate the entire mission pipeline from synchronous FastAPI handlers to Temporal workflows with full saga rollback semantics, heartbeats, and idempotency guarantees."
"Implement an in-memory caching layer with TTL, ETag/304 support, per-endpoint cache invalidation, cache statistics endpoint, and comprehensive integration tests."
Development environment
Delegate without leaving your editor. Approve the spec inline, the commit lands in your git panel. Native extension for both VS Code and Cursor Plugin Marketplace.
MAESTRO exposes a full Model Context Protocol server. Any MCP-compatible tool — Cursor, Windsurf, Claude Code — can trigger missions programmatically. One protocol, every IDE.
Tag @maestro on any issue or PR. MAESTRO opens a PR with the fix. GitLab CI/CD, self-hosted instances, and GitHub Actions templates all supported.
Research & intelligence
Live web search during every research phase. Current library docs, recent CVEs, updated API references. The debate is grounded in what is true today — not training data from months ago.
MAESTRO fetches any live URL during research — GitHub READMEs, internal Confluence pages, staging environments, public documentation. If it is reachable, it is readable.
Import project specs directly from Notion pages. Pull UI component specs from Figma designs. MAESTRO reads your actual documentation before the debate begins, not a summary of it.
Project context
MAESTRO reads your Supabase schema, Row Level Security policies, and edge function definitions before proposing any database change. No hallucinated migrations — the debate knows your actual data layer.
Meeting transcripts become project context. Architectural decisions made in a call, requirements discussed in a standup — MAESTRO reads them and feeds them into the research phase automatically.
Assign a Linear ticket directly to MAESTRO. Tag @maestro in any Slack channel. The spec approval appears in the thread. Your team sees exactly what will change before a single file is touched.
Deployment & testing
After a successful mission, MAESTRO triggers a Vercel deployment automatically. Your preview URL is live before you finish reading the commit message.
E2E tests run inside the Firecracker sandbox alongside your test suite. MAESTRO verifies that what it built actually works in a browser — not just that the unit tests pass.
When your test suite fails in CI, MAESTRO triggers automatically — analyses the failure, proposes a fix, opens a PR. Routine regressions fix themselves. Your engineers work on harder problems.
