Stop re-explaining your codebase every session. Memory, tasks, and governance that persist across Claude Code, Codex, Cursor, and Gemini CLI.
The universal command for the Delimit Swarm. When you say "Think and Build", your AI agents (Claude, Codex, Gemini, Cursor) automatically deploy a background autonomous build loop that monitors your ledger, deliberates on strategy, and implements code while you focus on the architecture.
- "Think": Trigger multi-model deliberation and strategic dispatch.
- "Build": Activate the background daemon to execute tasks and verify gates.
- "Vault": Manage local secrets and API keys (AES-256 encrypted).
Works across any configuration — from a single model on a budget to an enterprise swarm of 4+ models.

Run your question through 4 AI models simultaneously. They debate each other until unanimous agreement.
delimit deliberate "Should we build rate limiting in-house or use a managed service?" Round 1 (independent):
Claude: Build in-house. Redis sliding window is 50 lines.
Gemini: Build. You already have Redis.
Codex: Agree — but add circuit breaker for Redis failures.
Grok: Build. Managed service costs $200/mo for 50 lines of code.
Round 2 (deliberation):
All models: AGREE
UNANIMOUS CONSENSUS (2 rounds, confidence 94/100)
Build rate limiting in-house with Redis + circuit breaker.

- API governance -- lint, diff, policy enforcement, semver classification
- Persistent ledger -- track tasks across sessions, shared between all AI assistants
- Zero-spec extraction -- generate OpenAPI specs from FastAPI, Express, or NestJS source
- Project scan -- auto-detect specs, frameworks, security issues, and tests
- Quickstart -- guided first-run that proves value in 60 seconds
- Multi-model deliberation -- AI models debate until they agree (free: Gemini Flash + GPT-4o-mini; BYOK: any models)
- Security audit -- dependency scanning, secret detection, SAST analysis
- Test verification -- confirms tests ran, measures coverage, generates new tests
- Memory & vault -- persistent context and encrypted secrets across sessions
- Evidence collection -- governance audit trail for compliance
- Deploy pipeline -- governed build, publish, and rollback
- OS layer -- agent identity, execution plans, approval gates

How does this compare to Obsidian Mind?
Obsidian Mind is a great Obsidian vault template for Claude Code users who want persistent memory via markdown files. Delimit takes a different approach: it's an MCP server that works across Claude Code, Codex, Gemini CLI, and Cursor. Your memory, ledger, and governance travel with you when you switch models. Delimit also adds API governance (27-type breaking change detection), CI gates, git hooks, and policy enforcement that Obsidian Mind doesn't cover. Use Obsidian Mind if you're all-in on Claude + Obsidian. Use Delimit if you switch between models or need governance.
Does this work without Claude Code?
Yes. Delimit works with Claude Code, Codex (OpenAI), Gemini CLI (Google), and Cursor. The remember/recall commands work standalone with zero config. The MCP server integrates with any client that supports the Model Context Protocol.
Is this free?
The free tier includes API governance, persistent memory, zero-spec extraction, project scanning, and 3 multi-model deliberations. Pro ($10/mo) adds unlimited deliberation, security audit, test verification, deploy pipeline, and agent orchestration.
