AC Browser Fu
Fixes browser automation failures. Snapshot-first workflow + API discovery behind any website UI. Use when: 'browser not working', 'can't click', 'flaky UI', 'DOM not exposed', 'scrape website', 'browser keeps failing', 'automate this website', 'web scraping', 'element not found'.
As a process C 51/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- 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)
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 (Browser Fu) differs from the folder (browser-fu)
- 60Tools and files. Uses tools (web) that frontmatter does not declare
- 100Steps. 21 steps
- 100Failures and branches. 5 branches, has a failure section
- 100Execution cost. Instruction body is 825 tokens
- 100Running it twice. No mutating operations
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

- +1No license
- +2Single-language instructions
- +3Description length 281: enough signal without eating the budget
- +4Structure: 8 headings
- +3Step-by-step instructions: 21 items
