llmsdottxt-mcp: Instructions file for Codex

AGENTS.md

llmsdottxt-mcp AGENTS.md is an instructions file for Codex, OpenCode from lehre-labs/llmsdottxt-mcp. It costs 1,430 tokens per session, scanned A, original, Apache-2.0.

Project instructions for llmsdottxt-mcp, including its central idea, terminology, context files, and coding principles. An AGENTS.md file is a set of instructions that an AI coding agent reads before modifying a project.

In plain words
What is it for?
Preparing changes, checking project context, using the correct terminology, surfacing conflicts, and following the project's simplicity and design rules.
Why use it?
They keep changes aligned with the project's stated purpose and prevent the agent from guessing at names, goals, or non-goals.

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

This is lehre-labs/llmsdottxt-mcp's own configuration. It tells Codex and OpenCode how to work on llmsdottxt-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 llmsdottxt-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

llmsdottxt-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 7d 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.

AGENTS.md

This is llmsdottxt-mcp. Before doing anything else, read pyproject.toml so you know what we're building.

1. Build Around ONE IDEA

Read @IDEA.md first. Every change must serve the thesis it states.

This project exists for one reason. @IDEA.md names it, along with the non-goals that bound it. Before any change:

  • If the change doesn't serve the IDEA, it doesn't belong here -- say so.
  • If it lands in a documented non-goal, stop and flag the conflict.
  • If the IDEA itself is unclear or seems wrong for the request, surface that before coding -- don't silently reinterpret it.

2. Read the Context

Before writing any code, understand the user's request and the project's language.

  • Read @CONTEXT-MAP.md and @CONTEXT.md -- they define what things are called.
  • If the term you need is missing, define it there before using it.
  • If the user used the wrong term, use the canonical one and note the discrepancy.
  • A wrong name in code is worse than a bug.

3. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

  • State your assumptions explicitly. If uncertain, ask.
  • If multiple interpretations exist, present them -- don't pick silently.
  • If a simpler approach exists, say so. Push back when warranted.
  • If something is unclear, stop. Name what's confusing. Ask.

4. Simplicity First

Minimum code that solves the problem. Nothing speculative.

  • No features beyond what was asked.
  • No abstractions for single-use code.
  • No "flexibility" or "configurability" that wasn't requested.
  • No error handling for impossible scenarios.
  • If you write 200 lines and it could be 50, rewrite it.

Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

5. Surgical Changes

Touch only what you must. Clean up only your own mess.

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.
