BC automation_browser
Control Browser's kernel for web automation. Supports web navigation, element interaction, page scrolling, file/video downloading, and content extraction.
As a process C 51/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
ReferenceInfrastructureMedia and videotype and topics are labelled automatically from the skill text
How to improve
- Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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
- warning
name-formatname should be kebab-case (lowercase letters, digits, hyphens) - warning
description-no-whendescription does not say WHEN to use the skill (no "use when")
Process rating: all ten parameters 51/100
- 0Result and completion. Does not say what the result is
- 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 (automation_browser) differs from the folder (automation-browser)
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 100Steps. 8 steps
- 100Failures and branches. 3 branches, has a failure section
- 100Execution cost. Instruction body is 1298 tokens
- 100Running it twice. No mutating operations
- low The response is described with custom markup (5 tags): a typed call is more reliable
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 signals

ClawHub: suspicious
This browser automation skill is mostly purpose-aligned, but it installs system software, starts a background local service, writes logs, and logs typed text in ways users should review before installing.
