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

This is Miraculix2050/LoxBerry-Plugin-MCP-Server's own configuration. It tells Codex and OpenCode how to work on LoxBerry-Plugin-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 LoxBerry-Plugin-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

LoxBerry-Plugin-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 8d 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.

Project Instructions

This repository contains the LoxBerry MCP Server plugin. Apply the mandatory rules below to every change. Before implementation, read only the relevant sections of docs/development/implementation-guidelines.md: sections 3-6 for architecture, MCP contracts, security, or configuration; section 7 for UI; section 8 for lifecycle; section 9 for logging; and sections 10-11 for tests, documentation, or releases. Read the whole document only for cross-cutting or unclear changes. Select verification from docs/development/test-strategy.md; do not reread unchanged sections during the same task.

Working rules

  • Keep changes small and compatible with the native LoxBerry plugin layout.
  • Treat MCP tool names, input/output schemas, configuration keys, plugin identity, and persistent paths as contracts once released.
  • Separate Loxone authorization from LoxBerry authorization. Never infer administrative LoxBerry permissions from a Loxone login.
  • Default new capabilities to read-only. Mutating tools require an explicit, narrow allowlist, input validation, authorization, timeout handling, and an audit record.
  • Keep developer-facing code, comments, logs, and technical diagnostics in English. Keep German and English user-facing UI and documentation synchronized.
  • Never store or print credentials, tokens, session data, or private keys.
  • Update documentation and tests together with behavior, configuration, permissions, dependencies, compatibility, or upgrade changes.
  • Use change-driven tests. Documentation-only changes do not require device or browser acceptance unless they change generated or rendered behavior.
  • During iteration use python tools/test.py --profile changed; inspect the selection first with --plan when scope is unclear. Reserve the Full profile for the final revision, cross-cutting fallback, CI, and release packaging.
  • Do not claim platform, browser, device, or Miniserver compatibility without matching evidence.
  • Preserve unrelated worktree changes and inspect git status --short before committing.
  • Prepare release metadata and CHANGELOG.md through a reviewed PR. Official stable and prerelease packages, tags, and GitHub Releases must be created only from prepared master with the owner-triggered Publish plugin release workflow. AI agents invoke that same workflow with gh workflow run; local -local-... ZIPs are test artifacts only.

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.
