At a glance

Reference for MATLAB audiostreamer (Audio Toolbox R2025a+). An agent skill from matlab/matlab-agentic-toolkit.

  • Writing code for audio playback
  • SKILL.md covers When to Use, When NOT to Use, Construction and Properties, plus 7 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Full-duplex device I/O

What it does

Matlab Play Record Audio is an agent skill from matlab/matlab-agentic-toolkit. Reference for MATLAB audiostreamer (Audio Toolbox R2025a+). Without this skill, agents consistently default to legacy audioDeviceWriter/audioDeviceReader or base MATLAB sound(), producing less capable code. Use when writing code for audio playback, recording, full-duplex device I/O, real-time audio measurements, or audio I/O processing with callbacks. Also use when debugging audiostreamer errors, dropouts, or latency issues, or migrating from audioDeviceReader, audioDeviceWriter, audioPlayerRecorder, or…

Its SKILL.md is about 5.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `manifest.yaml`).

It sits in Development. The repository describes itself as: The MATLAB Agentic Toolkit brings proven MATLAB capabilities to AI agents, making engineering and scientific workflows agent-ready.

When your agent uses it

  • Writing code for audio playback
  • Full-duplex device I/O
  • Real-time audio measurements
  • Audio I/O processing with callbacks

Example prompts

  • “/matlab-play-record-audio”

What it can do on your machine

Read from SKILL.md and the folder at commit 69e71df. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are matlab).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Matlab Play Record Audio loads about 5.3k tokens when it runs. Until then it costs about 140 tokens; SKILL.md has 1,748 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~140
When it runs · the whole SKILL.md, loaded when a task matches
~5.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,748 words (~5,315 tokens).

“audiostreamer is the unified replacement for audioDeviceWriter, audioDeviceReader, and audioPlayerRecorder. It provides player-only, recorder-only, or full-duplex modes with callbacks, pre-buffering, transport control, and measurement helpers.”
