As a process C 60/100 · Has gaps — weak spots: when it triggers, inputs and preconditions, consistency
This is a copy of a skill from another catalog; the rating counts the canonical one: video-downloader (ClawHub)
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.

Process rating: all ten parameters 60/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 40Consistency. Frontmatter name (video-downloader) differs from the folder (multi-platform-video-downloader)
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 100Steps. 50 steps
- 100Failures and branches. 1 branches, has a failure section
- 100Execution cost. Instruction body is 1371 tokens
- 100Running it twice. No mutating operations
- low 11 top-level sections: this looks like several domains in one skill
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.

ClawHub: suspicious
This appears to be a real video downloader, but it can automate browser-backed downloads using cookies or logged-in session context without enough containment or consent controls.
