ultrabrain-mcp: Instructions file for Codex

AGENTS.md

ultrabrain-mcp AGENTS.md is an instructions file for Codex, OpenCode from LCV-Ideas-Software/ultrabrain-mcp. It costs 2,158 tokens per session, scanned A, original, Apache-2.0.

A set of project instructions for AI agents working on the ultrabrain-mcp TypeScript repository. MCP is a standard way for an AI agent to communicate with external tools and services.

In plain words
What is it for?
Use it when developing, testing, packaging, or preparing releases for the ultrabrain-mcp project.
Why use it?
It gives agents the repository's required structure, naming rules, tests, formatting checks, packaging checks, and release constraints. This helps prevent invalid changes or accidental publishing.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is LCV-Ideas-Software/ultrabrain-mcp's own configuration. It tells Codex and OpenCode how to work on ultrabrain-mcp 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 ultrabrain-mcp 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

ultrabrain-mcp 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 1mo 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.

Runtime Shape

This repository is a TypeScript MCP stdio server. Source lives in src/, build output lives in dist/, and the runtime entry point is dist/index.js.

The public MCP surface is LCV-branded. Tool names must use the ultrabrain_* prefix. Do not add legacy third-party tool names as public aliases.

Mandatory Gates

npm test
npm run biome
npm run format:public:check
npm pack --dry-run

For local MCP runtime checks after installation:

ultrabrain-mcp

Do not run the server directly in a blocking shell unless it is attached to an MCP client or a smoke harness; stdio MCP servers wait for protocol input.

Release and Publishing

  • Do not publish from the workstation.
  • publish.yml runs on pushes to main touching package.json; only a changed package version initiates publication. Dependency-only manifest edits do not.
  • Its four jobs build and pack once without publishing permissions, publish the same tarball to npmjs.com through OIDC in npm-production, mirror it to GitHub Packages with GITHUB_TOKEN, then create the padded tag and GitHub Release last.
  • The first public release was v01.00.00 from npm package version 1.0.0. Current tags retain the padded display convention (v00.00.00); npm uses SemVer.
  • Do not restore auto-tagging, administrative PAT gates, release-policy engines or a custom npm bootstrap. Retain product build, bundled-license verification and clean-consumer tests; these are not retired governance controllers.
  • An existing tag does not prove publication succeeded. Check partial registry writes before a native gh run rerun RUN_ID --failed; reruns are best effort, not an exactly-once transaction. Do not move or recreate historical tags.
  • CodeQL uses Default Setup. Native Dependabot auto-merge, Dependency Review, Zizmor, Scorecard and Linear Release follow the repository-local baseline.
  • GitHub Pages serves site/ through the custom domain ultrabrain-mcp.lcv.dev.
  • Direct third-party uses: references in this repository's workflows must remain pinned to reviewed immutable commit SHAs. After the operator-directed retirement of actions.lock, nested actions resolve according to the official upstream action manifests; direct pins do not guarantee immutable transitive references.

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.
