nobu AGENTS.md

nobu AGENTS.md is an instructions file for Codex, OpenCode from francescojr/nobu. It costs 2,081 tokens per session, scanned A, original, MIT.

Repository instructions for nobu, a game-agnostic MCP server for composing chiptune and retro MIDI and rendering game audio. They define required setup actions, project paths, and rendering behavior.

In plain words
What is it for?
Running the bootstrap script, integrating nobu with a game project, using its asset and output folders, and producing audio in the required render modes.
Why use it?
They give coding agents a consistent procedure for setting up the repository and handling its generated files.

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

nobu 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 4d 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.

AGENTS.md — nobu

Instructions for coding agents (Cursor, Claude Code, Kilo Code, etc.). Humans: see README.md. Setup detail: .claude/skills/game-music-producer/SETUP.md.

If this workspace was just cloned: run bootstrap immediately. Do not ask.

Mission

nobu is a game-agnostic MCP server + skill for composing chiptune/retro MIDI and rendering game audio. It ships no game-specific data.

First actions after clone (mandatory, automatic)

Trigger this checklist when: the user says install/setup/use nobu, the repo was just cloned, imports fail, or MCP tools are missing. Do not ask for confirmation.

  1. Bootstrap (from repo root):

    python scripts/bootstrap.py --no-prompt

    Humans may run python scripts/bootstrap.py without flags for an interactive optional-upgrade menu.

    This creates .venv, installs deps, ensures folders, verifies imports, and rewrites project-local .cursor/mcp.json + .mcp.json (Cursor) and .kilo/kilo.jsonc (Kilo) with the venv Python + absolute nobu_mcp.py (all gitignored; templates *.example* stay in git).

    Integrate into a game project:

    python scripts/bootstrap.py --integrate /absolute/path/to/game --no-prompt

    Machine-readable status:

    python scripts/bootstrap.py --json --no-prompt

    Optional flags:

    python scripts/bootstrap.py --with-render --no-prompt   # tinysoundfont (hybrid)
python scripts/bootstrap.py --doctor                   # re-check deps, no pip/menu
python scripts/bootstrap.py --smoke --no-prompt        # end-to-end chip render proof

    Kilo: bootstrap writes "timeout": 300000 in .kilo/kilo.jsonc. Also set Settings → MCP → nobu → Network Timeout → 5 minutes if render fails with -32001. Prefer MCP render_chip for first audio; use shell fallback:

    python scripts/render_track.py assets/midi/{project}.mid --mode chip --json

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.
