mcp: Instructions file for Codex

AGENTS.md

agents-entry-point is an instructions file for Codex, OpenCode from LXVault/mcp. It costs 2,220 tokens per session, scanned A, original, MIT.

A project instruction guide that tells coding agents how to work in LXVault’s MCP repository, including its agent folders, branches, commits, and security checks.

In plain words
What is it for?
Use it when changing agent-related files, creating branches, reviewing repository rules, or finishing and checking committed code.
Why use it?
It prevents agents from editing protected instruction files without approval and reduces mistakes in branching, documentation, and repository structure.

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

This is LXVault/mcp's own configuration. It tells Codex and OpenCode how to work on 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 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

agents-entry-point 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.

How it starts

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS

This repository is mcp-rag-mcp-server, a Model Context Protocol server that exposes the MCP RAG knowledge base to MCP compatible clients such as Claude Desktop and IDE assistants. It speaks JSON-RPC over stdio and holds no state and no logic of its own: every tool is a thin call to the Express backend in LXVault/server-expressjs, carrying a per project access token so the backend can attribute each action to the user who issued that token.

Shared Instruction Set

The conventions this repository follows, branching, commits, pull requests, task workflow, the creators, live in the shared instruction set served by the lxagents-agents-base MCP server. This repository carries only what is its own. Resolve the shared set before doing any work:

  1. If the lxagents-agents-base connector is available in this session, that is the shared set. Refer to it as {shared}; its files are addressed as agents://{folder}/{file}.md.
  2. Resolving is not loading. Do not pull any convention at session start. The Shared instruction tools block below declares which tools this repository uses and the trigger for each; call one when its trigger fires, and not before.
  3. Where the client exposes no tools, the same conventions are read as agents://{folder}/{file}.md resources, on the same triggers. list_shared_agents_instruction, or agents://manifest.json, answers "what exists?" in one call. Do not bulk-read the set.
  4. If the connector is not available, say so plainly and continue with this repository's local instruction set only. Do not reconstruct the missing rules from memory, and do not clone or copy them into this repository.

The declaration block is required. A repository without one has no routing table, so nothing fires and the omission looks exactly like a session in which no convention happened to apply. It names the four mandatory tools at minimum, task_workflow, branch_strategy, commit_strategy, discovery_protocol, and stamps the set version adopted. Shape: {shared}/prompts/agents-setup.md. Keeping it current when this set moves: {shared}/prompts/agents-update.md, on request.

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.
