diataxis-mcp-server: Instructions file for Codex

AGENTS.md

diataxis-mcp-server AGENTS.md is an instructions file for Codex, OpenCode from willermo/diataxis-mcp-server. It costs 116 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for an MCP server that applies Diátaxis, a framework for organising technical documentation by its purpose.

In plain words
What is it for?
Use them when modifying the Diátaxis MCP server, especially its core logic, MCP registration, documentation-derived content, or heuristics.
Why use it?
They tell coding agents which reference material to read, where code belongs, how to handle licensing, and when tests are required.

Instructions file for CodexOpenCode

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

This is willermo/diataxis-mcp-server's own configuration. It tells Codex and OpenCode how to work on diataxis-mcp-server 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 diataxis-mcp-server configures →

Borrowing it

Nothing to install: this file belongs to willermo/diataxis-mcp-server. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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

diataxis-mcp-server 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

Agent instructions

This project implements an MCP server for applying Diátaxis to documentation workflows.

Before editing core logic:

  • Read references/diataxis/sources.md.
  • Read references/diataxis/diataxis-operational-summary.md.
  • Keep Diátaxis-derived material short, attributed, and compatible with CC-BY-SA 4.0.
  • Do not copy long verbatim upstream content into source files.
  • Keep core logic in src/core.
  • Keep MCP registration in src/mcp.
  • Add tests for every new heuristic.
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.
