AGENTS.md

mentisdb AGENTS.md is an instructions file for Codex, OpenCode from CloudLLM-ai/mentisdb. It costs 176 tokens per session, scanned A, original, MIT.

Repository instructions for mentisdb, a Rust library for durable memory, storage, search, and data export. They set boundaries between this library and cloudllm and describe standards for its public API and tests.

In plain words
What is it for?
Use them when changing public Rust code, persistence or serialization, retrieval, exports, tests, or crate metadata.
Why use it?
They prevent architectural drift and make sure new behavior, stored data, and published crate details follow the project's rules.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is CloudLLM-ai/mentisdb's own configuration. It tells Codex and OpenCode how to work on mentisdb itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mentisdb configures →

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.

Security

Grade A, and why

mentisdb AGENTS.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.

What it actually says

mentisdb Standards

mentisdb follows the same engineering bar as cloudllm.

Scope

  • mentisdb is a standalone crate.
  • cloudllm may depend on mentisdb.
  • mentisdb must not depend on cloudllm.

Standards

  • Public API changes require rustdoc on exported types and functions.
  • New behavior requires tests.
  • Serialization and persistence changes must preserve explicit integrity checks.
  • Retrieval and export features should be generic enough to support direct crate use, MCP services, REST services, and CLI tools.
  • Crate metadata must remain suitable for crates.io publishing.

Design Bias

  • Prefer semantic memory primitives over agent-framework-specific abstractions.
  • Keep storage durable and append-only.
  • Keep query and export APIs first-class, not bolted on as prompt helpers.
Changes

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.
