FD kanecli-skill
Browser automation + AI test authoring via kane-cli - run browser objectives, generate & refine test scenarios/cases from a description, design requirement-linked test suites from a PRD/spec (assurance), parse NDJSON output, inspect logs, save runnable _test.md. Use for any task requiring a real browser (navigate, click, fill forms, test web UI, take screenshots), or to author test cases, quick cases from a description via kane-cli generate; a designed, coverage-accounted suite from requirement documents via the assurance commands. Never write test cases by hand. Also runs mobile app tests - native Android app on a virtual emulator or iOS app on a simulator via --target emulator|simulator (desktop browser stays the default target): locally on macOS Apple Silicon, or on the LambdaTest cloud grid from any machine via kane-cli testrun run --remote. Also shares the assurance store (.context/) with a team through a location (a GitHub repository, an S3-compatible bucket, or a folder) via kane-cli context sync, and resolves the decisions a sync rebase asks.

What is at stake
The skill contains fragments that, in the wrong hands, cost money or data. Below: what the installer risks and what the author should do.
The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".
If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
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.
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
- Address the high-severity findings: each costs 18 safety points. If one is a false positive, add the rule id to guard.allow in spec.yaml.
- Shorten the description to 1024 characters.
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- 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.

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.
