ComfyUI-WhisperCPP: Instructions file for Codex

AGENTS.md

ComfyUI-WhisperCPP AGENTS.md is an instructions file for Codex, OpenCode from obvirm/ComfyUI-WhisperCPP. It costs 2,028 tokens per session, scanned A, original, Apache-2.0.

Project instructions for a ComfyUI custom node that transcribes audio with whisper.cpp, with optional speech alignment and speaker identification. ComfyUI is a visual system for building media-processing workflows from connected nodes.

In plain words
What is it for?
Use them when modifying audio loading, transcription, model downloads, vocal separation, word alignment, diarization, or ComfyUI node registration.
Why use it?
They require changes to be tested and verified in a real workflow, reducing the risk of relying on guessed API details or untested behavior.

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

ComfyUI-WhisperCPP AGENTS.md scanned grade A with 1 finding 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 2mo 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.

Expected in a hook, worth knowing in a rule or an instructions file.

AGENTS.md — ComfyUI-WhisperCPP

Tujuan

Custom node ComfyUI untuk transkripsi audio pakai whisper.cpp (C API via ctypes), tanpa whisperx.
Full pipeline: ASR (whisper.cpp native) → Alignment opsional (torchaudio wav2vec2) → Diarization opsional (pyannote.audio).

Aturan Main

1. GAK BOLEH NGE-GAS TANPA VERIFIKASI

  • Setiap perubahan: test dulu. Jangan ngarep "mungkin work".
  • End-to-end: bikin workflow ComfyUI beneran, inject prompt, verifikasi output.
  • Jangan pernah nebak properti API tanpa riset dulu.

2. Struktur Folder

├── whispercpp_node.py       # class WhisperCPPNode (ComfyUI node)

├── whispercpp.json          # model config
└── MEMD.md                  # project memory

3. Output WAJIB lewat Node Connection

  • filename_prefix dan output_format DILARANG — output cuma lewat 7 socket: text, segments_json, srt, vtt, tsv, aud, json_result
  • Semua format generate di memory (_make_outputs), gak ada file I/O.

4. JS Toggle (Frontend)

  • Dua toggle independent: show_advance_cpp dan show_advance_ext.
  • Approach: grab widget reference di onNodeCreated, simpen di closure.
  • Show/Hide: JANGAN pakai widget.hidden (belum tentu real).
  • JANGAN main-main this.widgets dengan cara yang bikin reference ilang.
  • Selalu setTimeout biar widget kebentuk dulu.

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.
