ableton-cli: Instructions file for Codex

AGENTS.md

ableton-cli AGENTS.md is an instructions file for Codex, OpenCode from 6uclz1/ableton-cli. It costs 2,160 tokens per session, scanned A, original, MIT.

Repository instructions for ableton-cli, a command-line program that controls and inspects Ableton Live, a music-production application. They require test-driven development, or writing a failing test before the code that makes it pass.

In plain words
What is it for?
Adding or changing Ableton Live commands, validation, JSON output, exit codes, tests, and connections to the local Ableton control script.
Why use it?
They keep commands predictable, errors visible, and behavior consistent for both people and automation. They also prevent hidden fallback paths and duplicated logic.

This is 6uclz1/ableton-cli's own configuration. It tells Codex and OpenCode how to work on ableton-cli 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 ableton-cli 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

ableton-cli 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 12d 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.

Purpose

Repository-level instructions for coding agents working on ableton-cli.

Keep this file stable and operational. Do not duplicate the full command catalog here. Use the source documents listed below for command coverage, action mappings, examples, and contributor workflow details.

Project Context

ableton-cli is a Python CLI for controlling and inspecting Ableton Live through a local Remote Script. The project is intended for both humans and automation, so deterministic CLI behavior, stable JSON output, fixed exit codes, and explicit failures are part of the product surface.

Non-Negotiable Principles

  • TDD: use red -> green -> refactor for behavioral changes.
  • DRY: do not duplicate command logic, validation, tests, fixtures, or documentation.
  • SOLID: keep modules focused; make dependencies explicit and injectable where practical.
  • No silent degradation: fail explicitly with the correct error code and hint.
  • No compatibility shims: do not add deprecated aliases, dual-path behavior, or legacy adapters unless explicitly requested. If a public contract changes, update the contract artifacts instead of preserving both behaviors.

Source of Truth

Use these repository-relative documents before changing behavior:

  • README.md — user-facing setup, command examples, global option placement, protocol, security model, exit codes.
  • CONTRIBUTING.md — developer workflow, public contract boundary, quality harness, merge gates.
  • skills/ableton-cli/SKILL.md — agent-facing command catalog.
  • docs/skills/skill-actions.md — stable automation action names and CLI mappings.
  • docs/skills/examples/*.json — machine-oriented examples.
  • .cursor/rules/ableton-cli.mdc — Cursor-specific conventions mirroring this file.
  • .quality-harness.yml and docs/quality-harness-phase2.md — quality harness thresholds and limits.
  • docs/plugins.md — plugin API, packaging and GitHub installation.
  • docs/computer-use/README.md — Computer Use fallback policy and GUI playbooks for operations the CLI cannot perform.

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.
