What is Muninn GEMINI.md?

Project instructions for developing Muninn MCP, a local-first system that stores and retrieves persistent assistant memory. MCP is a standard way for AI assistants to use external tools.

Use them when changing Muninn MCP, especially to understand its design, follow its development practices, and update the relevant project files.

They keep contributions aligned with the project's architecture, quality expectations, and requirement for production-ready code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00815	$0.00815
Opus 5.5	$0.00326	$0.00326
Sonnet 5.5	$0.00163	$0.00163
Haiku 4.5	$0.00081	$0.00081

Security

Grade A, and why

Muninn GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Muninn MCP — SOTA+ Development Context

Role: Muninn is a local-first, assistant-agnostic persistent memory infrastructure designed to outstrip existing systems (like Mem0 or Serena) through deterministic retrieval, neuroscience-inspired consolidation, and production-grade operational controls.

Core Mandate: This project is developed using Muninn to develop itself. Every contribution must meet SOTA+ (State of the Art Plus) standards of precision, quality, and logic.

🚀 SOTA+ Development Philosophy

Production-Grade Only: NEVER use placeholders, stubs, or "samples" for core logic. All code must be production-ready, typed, and robust.
Evidence-Driven Logic: Every decision must be grounded in the codebase's existing architecture (docs/ARCHITECTURE.md) or the SOTA+ implementation plan (SOTA_PLUS_PLAN.md).
Optimal Reasoning: Question every assumption. Understand the implications of every choice. Avoid illogical or unsound reasoning at all costs.
Tool-First Execution: Always leverage the most powerful tools available (MCPs, research tools, context7) to ensure a comprehensive grasp of the project before acting.
Quality Over Speed: Never sacrifice precision for speed. A correctly implemented, well-tested feature is the only acceptable outcome.

🛠 Operational Guidelines (Always-On)

When working on Muninn, the following modes are strictly enforced:

--orchestrate: Manage multi-step implementations with clear planning and checkpoints.
--ultrathink: Perform deep, reflective reasoning on architectural impacts before modification.
--uc (Ultra-Compressed): Maintain maximum token efficiency in communication without losing clarity.
--delegate: Use sub-agents for parallel analysis or specialized investigation when appropriate.
--all-mcp: Utilize all available Model Context Protocol tools to verify state and context.
--task-manage: Track progress through the SOTA_PLUS_PLAN.md phases rigorously.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
