audio-plugin-coder: Instructions file for Codex

AGENTS.md

audio-plugin-coder AGENTS.md is an instructions file for Codex, OpenCode from Noizefield/audio-plugin-coder. It costs 1,482 tokens per session, scanned A, original, MIT.

Project instructions for Audio Plugin Coder, a system for creating audio plugins. They define its setup process, configurable paths, release locations, attribution rules, and limits on actions taken in an agent's name.

In plain words
What is it for?
Use them when setting up the project, creating or shipping audio plugins, finding configured directories, preparing installers, or writing commits and public project messages.
Why use it?
They prevent plugins and release files from being placed in the wrong directories and stop an agent from adding misleading authorship or posting publicly as an AI. They also identify the required setup before plugin work begins.

Instructions file for CodexOpenCode

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

This is Noizefield/audio-plugin-coder's own configuration. It tells Codex and OpenCode how to work on audio-plugin-coder 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 audio-plugin-coder 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

audio-plugin-coder 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 28d 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.

Audio Plugin Coder — Agent Guidance

Scope

These instructions apply to the entire repository and are written for any coding agent that reads the AGENTS.md standard (Codex, Cursor, Pi, Antigravity, OpenCode, and others). Canonical APC knowledge lives under .agents/ (skills/, workflows/, rules/, guides/, troubleshooting/). Host-specific folders (.claude/ for Claude Code, .kilocode/ for Kilo, .agent/ legacy, .opencode/command/ for OpenCode, .devin/skills/ for Devin, .pi/ if present) contain pointers to those canonical files; treat them as equivalent.

First run

  • New checkouts should start with /apc-setup (skill action setup) before creating plugins.
  • Setup writes machine-local apc.config.json (see apc.config.example.json). Paths, UI defaults, and per-phase model preferences live there.
  • Resolve plugin/build/release directories via scripts/lib/Get-ApcPaths.ps1 or scripts/lib/apc-paths.sh — do not assume ./plugins if config overrides exist.
  • /apc-ship writes installers and zips to paths.release_dir (default release/). Do not use dist/ as the ship output.

Attribution

  • Do not add Co-authored-by trailers for AI agents.
  • Do not list AI agents as contributors, authors, or acknowledgments.
  • Do not post GitHub comments, reviews, or issues in the name of an AI agent.
  • If a host injects an AI co-author trailer into a commit message, strip it before the commit is pushed.

APC Workflow

  • Use the audio-plugin-coder skill for APC lifecycle work.
  • Primary slash commands are prefixed: /apc-setup, /apc-dream, /apc-plan, /apc-design, /apc-impl, /apc-test, /apc-debug, /apc-ship, /apc-status, /apc-resume, /apc-new, /apc-orchestrate.
  • Short forms (/dream, /design, /impl, …) remain as deprecated aliases that redirect to /apc-*.
  • Claude Code and Kilo use the bare /apc-* forms. Codex repo sessions use the audio-plugin-coder skill action; plugin surfaces may expose namespaced command adapters, but they do not create bare /apc-* aliases.
  • Devin exposes repo skills as slash commands via .devin/skills/apc-*/SKILL.md pointers to .agents/workflows/apc-*.md. /apc-setup is namespaced (/devin:apc-setup, /agents:apc-setup, /claude:apc-setup) because same-named skills exist in multiple imported dirs.
  • If the agent host does not expose slash commands, use the audio-plugin-coder skill or an equivalent natural-language request.

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.
