MIRA v0.290.0 — public beta

The current public-beta build of MIRA — a self-hostable, single-binary personal AI agent that runs on hardware you control. A project of Vexillon. Licensed under AGPL-3.0-or-later.

⚠️ Public beta (pre-release). Recommended build for new installs; supersedes v0.289.0.

New / improved

• MIRA can create agents & workflows for you — new chat tools create_named_agent and create_workflow let MIRA save reusable agent profiles and multi-step workflow DAGs on request (previously UI/API-only). They reuse the existing stores and validation, so anything MIRA creates shows up on the Agents and Workflows pages.
• Pending-approval reminders — the daily briefing and companion check-ins now surface agent-created schedules and wiki review-queue edits that are awaiting approval. New pending_approvals (summarise) and approve_pending (approve any/all) tools let you action them just by replying.
• Anti-confabulation guardrails — the base system prompt and check-in/briefing cues now forbid claiming actions, files, commits, or builds the agent didn't actually perform, and ban invented recency or dates.
