AB datalens
Use DataLens MCP tools to scrape structured data from any website open in Chrome. Triggers when the user wants to extract lists, tables, comments, products, reviews, or any repeating data from a webpage, or wants to manage active scraping jobs.

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 71/100
- 0Result and completion. Does not say what the result is
- 40Consistency. Frontmatter name (datalens) differs from the folder (datalens-web-scraper)
- 60Tools and files. Uses tools (bash, web, node) that frontmatter does not declare
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Steps. 13 steps
- 100When it triggers. States when to use and when not to
- 100Failures and branches. 3 branches, has a failure section
- 100Execution cost. Instruction body is 1731 tokens
- 100Running it twice. No mutating operations
- 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.

ClawHub: suspicious
This scraping skill is coherent, but it gives an agent broad access to a live Chrome session and exported webpage data without strong consent boundaries.
