ESPHome-MCP: Instructions file for Codex

AGENTS.md

ESPHome-MCP AGENTS.md is an instructions file for Codex, OpenCode from loryanstrant/ESPHome-MCP. It costs 178 tokens per session, scanned A, original, MIT.

Repository instructions for a coding agent working on ESPHome-MCP. They point the agent to the repository map, live issue and pull-request data, and listed build, test and lint checks.

In plain words
What is it for?
Use them when exploring the repository, finding files and symbols, checking live project work, or determining which validation steps are available.
Why use it?
They give an agent a defined starting point and warn it not to edit generated navigation files by hand. The validation commands are marked as TODO, so no completed checks are provided.

Instructions file for CodexOpenCode

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

This is loryanstrant/ESPHome-MCP's own configuration. It tells Codex and OpenCode how to work on ESPHome-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 ESPHome-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

ESPHome-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 17d 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

Start here (generated)

  1. Read NAVIGATION.md - the repository map: docs, headings, entry points, public symbols, operations.
  2. Use .agent/navigation.json when structured paths are easier to consume than prose.
  3. Use the Gitea MCP server for live state: issues, pull requests, CI results.

Do not hand-edit NAVIGATION.md or .agent/navigation.json; they are generated by navgen (tools/navgen/navgen repo in dev-standards) and refreshed nightly.

Validation

  • Build: TODO
  • Test: TODO
  • Lint: TODO
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.
