Hubitat-local-MCP-server: Instructions file for Codex

AGENTS.md

Hubitat-local-MCP-server AGENTS.md is an instructions file for Codex, OpenCode from kingpanther13/Hubitat-local-MCP-server. It costs 18,158 tokens per session, scanned A, original, MIT.

Repository instructions for Hubitat-local-MCP-server, including its commands, coding rules, and tool-naming requirements. Hubitat is a smart-home platform, and Groovy is the programming language used by this server.

In plain words
What is it for?
Use them when changing the server, writing Groovy tools or rules, running tests, or checking code before pushing.
Why use it?
They explain the project's special restrictions and checks, reducing the chance of code that Hubitat cannot run or that CI rejects.

Instructions file for CodexOpenCode

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

This is kingpanther13/Hubitat-local-MCP-server's own configuration. It tells Codex and OpenCode how to work on Hubitat-local-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 Hubitat-local-MCP-server 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

Hubitat-local-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 5d 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 — 358 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Conventions for AI coding agents working on this repo (OpenAI Codex, Cursor, Aider, Windsurf, Zed, etc.). Claude Code reads CLAUDE.md, which is kept byte-identical to this file — the PR Guard CI workflow flags drift. AGENTS.md is the source of truth. Edit it, then cp AGENTS.md CLAUDE.md before committing. (GitHub Copilot uses .github/copilot-instructions.md; .gemini/styleguide.md drove Gemini Code Assist's reviews — that bot is sunset and disabled, its replacement TBD.)

This file is for AI agents. Human contributors follow .github/pull_request_template.md and .gemini/styleguide.md.

Commands

./gradlew test                     # full Spock suite (~1 min)
./gradlew test --tests "<spec>"    # single spec
python tests/sandbox_lint.py       # Groovy sandbox lint
./gradlew -p ci/groovy24-parse parse24  # Hub Groovy 2.4 syntax, closure-parameter and sandbox-allowlist guard

Run all three before pushing, or rely on the corresponding CI lanes. Python lint does not run the AST closure-parameter guard. CI runs the same checks.

Code style

Hubitat Groovy sandbox (hubitat-mcp-server.groovy, hubitat-mcp-rule.groovy) blocks several JVM features the runtime would otherwise expose. Highlights — see tests/sandbox_lint.py for the full set:

  • Eval.*, GroovyShell, Class.forName, Runtime.exec, new Thread, new File / java.io.File — not allowed
  • getClass() — reflection blocked
  • log.isDebugEnabled() — not exposed
  • Date.format(String, Locale) — only the no-Locale overload works
  • Filesystem only via the hub File Manager API (/hub/fileManager); MCP-tool surface is list_files / read_file / write_file / delete_file

Use atomicState for thread-safe persistence, state for UI/counters. Compare device IDs as strings (.toString()).

Comments: only when the WHY is non-obvious. No multi-paragraph docblocks. Don't reference the caller. Issue/PR numbers are fine on the developer side (code comments, tests, repo docs such as this file), never in text the MCP server serves to users or AI clients (see § Tool descriptions).

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.
