soundcraft

soundcraft is a skill for Claude Code, Codex from BlackBeltTechnology/pi-agent-dashboard. It costs 91 tokens per session (2,254 once invoked), scanned A, original, MIT.

A headless audio editor and mixer for working with audio clips on one or more tracks. It supports clip volume changes, fades, normalising, mixing, and audio export.

In plain words
What is it for?
Use it to make audio quieter or louder, add fades, combine tracks, create a mix, and save the result as a WAV or another supported format.
Why use it?
It makes routine audio edits reproducible from commands instead of requiring a digital audio workstation, which is software for recording and mixing sound.

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

soundcraft 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 yesterday.

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.

SoundCraft — headless audio editing and mixing

SoundCraft is ArtCraft's DAW-style editor (sessions, tracks, clips, fades, mixer). pi-craft provisions the headless soundcraft-cli (no desktop app). Choosing between apps, the discover → execute → save → verify loop and the MCP policy live in craft-studio; this skill is the SoundCraft dialect and its traps.

What it is for / formats

Imports and bounces wav aiff flac (bounce: format, bit_depth 16/24/32f); info FILE summarises an audio file or a session. Project file: .scraft (the session; its audio lives in an Audio Files/ folder beside it). Hand-off to a video editor: bounce wav (see craft-studio).

CLI dialect

pi-craft soundcraft exec <args…> passes <args…> to soundcraft-cli verbatim. Unlike FilmCraft there is no exec <id>: one invocation = one run (a list of --cmds, optional bounce).

pi-craft soundcraft exec commands [FILTER]                  # list ids; FILTER is positional (see Traps)
pi-craft soundcraft exec describe <id>                      # params + "enabled" now / "disabled_reason"
pi-craft soundcraft exec run [--in S.scraft | --demo] --cmd ID[=JSON] [--cmd …] [--bounce OUT.wav] [--start SEC --end SEC] [--save S.scraft]
pi-craft soundcraft exec script FILE [--in S] [--save S] [--bounce OUT]   # FILE: one `ID JSON` per line
pi-craft soundcraft exec info FILE.wav|S.scraft             # file or session summary (track/clip listing)
pi-craft soundcraft exec run --in S.scraft --inspect        # session JSON: selection, sources, tracks
pi-craft soundcraft exec convert IN OUT [--bit-depth 16|24|32f] [--rate HZ] [--normalize]
  • Commands run in order and stop at the first failure (exit 1, no bounce written).
  • Each command prints id: {json} on stdout; --bounce prints one JSON line last: {"lufs":…,"peak_db":…,"true_peak_db":…,"seconds":…,"path":…} — read it, then confirm with pi-craft verify.
  • Params after = are one JSON object (--cmd 'clip.gain={"db":-6}'); a bare id has no params (--cmd edit.select_all).
  • Positions (at, length, start, end inside commands) are samples (48000 = 1 s at 48 kHz); --start/--end of run are seconds. Relative file paths are accepted.

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.
