Features
Local brain/ Markdown folder committed alongside your repo
Zero-dependency CLI in plain Node.js, installed via npm i -g @mindmux/brain-md
No runtime daemon, no MCP server, no network dependency
BRAIN.md at the project root as the protocol entry point any Markdown-reading agent can follow
Six fixed root pages: background, architecture, flow, mindmap, stack, roadmap
Six root pages are update-only, never created, with history kept in git
Five granular page categories under pages/: decision, concept, project, person, reference
compiled_truth section holding the current authoritative answer for a page
Append-only timeline with entry kinds: decision, evidence, reversal, note
brain update-truth atomically rewrites compiled_truth and appends the timeline entry in one write
Wiki-link cross-references in [[page-id]] syntax matched against the frontmatter id field
brain lint-links validates that every cross-reference resolves
brain reindex regenerates brain/index.md
brain-setup and brain-bootstrap scaffolding commands
Frontmatter fields: id, title, category, status, created, updated
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Serverless Workers host durable AI agents on Amazon Bedrock AgentCore
Serverless Workers on AWS Lambda (public preview) and GCP Cloud Run (pre-release)
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers sleep for months; cron Schedules support backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode enforces 15-min inactivity timeout and 12-hour max session (GA 2026-09-18)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI

Who should pick which

  • Solo developer using Claude Code for a complex app
    Pick: Brain.Md

    BRAIN.md provides persistent context across sessions without any runtime cost, perfect for maintaining project knowledge and avoiding re-explanations.

  • Team building a mission-critical AI agent with retries and recovery
    Pick: Temporal AI

    Temporal's durable execution and automatic state capture ensure the agent survives failures, and its OpenAI Agents SDK integration simplifies AI orchestration.

  • Open-source maintainer documenting decisions for AI contributors
    Pick: Brain.Md

    BRAIN.md's Git-versionable Markdown files make it easy to track architectural decisions alongside code.

  • Financial system needing Saga compensating transactions
    Pick: Temporal AI

    Temporal's Saga pattern via compensating transactions is specifically designed for such rollback scenarios.

  • Developer needing low-latency stateless APIs
    Pick: Brain.Md

    Temporal is overkill for stateless APIs; BRAIN.md is simpler and free, though it doesn't address API needs directly.
