BC go-music-api

Search songs, download playable audio, fetch lyrics, parse music share links, configure platform cookies, and switch music sources through a local go-music-api backend on Linux, macOS, and Windows. Use when the user asks to search music, play or download a song, get lyrics, resolve music share links, configure cookies for login-required tracks, or retry playback from another source after failures. If the backend is missing or unhealthy, install and start go-music-api first.

What is at stake

Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.

Dangerous commands medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

The skill contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.

For the author

Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.

How to improve

    For the model run — optional
    • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
    • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

    Against the Agent Skills spec

    • note frontmatter-key unknown frontmatter key "repository"

    Process rating: all ten parameters 63/100

    • 0Result and completion. Does not say what the result is
    • 0Inputs and preconditions. Does not say what the process needs to start
    • 40Consistency. Frontmatter name (go-music-api) differs from the folder (go-music-skill)
    • 60Tools and files. Uses tools (web, python) that frontmatter does not declare
    • 100Steps. 36 steps
    • 100When it triggers. States when to use and when not to
    • 100Failures and branches. 8 branches, has a failure section
    • 100Execution cost. Instruction body is 910 tokens
    • 100Running it twice. Mutating operations check current state
    • 100Progress reporting. Reports progress

    Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

    Quality base 70; lint remarks subtract, signals add up to 100. Result: 90.

    External checks

    ClawHub: suspicious
    The skill is a plausible music downloader, but it asks for sensitive account cookies and runs a downloaded background service without enough scoping or safety guidance.
