BC app-e2e-tests
Use when writing, changing, reviewing, or debugging Playwright e2e tests in packages/app/e2e (regression keepers and user stories). Covers the mocked opencode server harness and the Bun static server, per-test isolation, page-load and route cost, the suite-wide service-worker block, races with first mount, hover, measurement, clock, dialogs and shortcuts, projects, shards and worker scheduling, rehearsing Windows timing locally, and diagnosing a CI flake from its artifacts. Not for Storybook component tests or e2e/performance benchmarks.
A skill for Playwright e2e tests in the app/e2e package. Promises help with mocking the opencode server, Bun static server, test isolation, races on first mount, hover events, clocks and dialogs, sharding and worker scheduling. The file contains 4672 tokens of code without scripts—it's an instruction set, not a ready-made toolkit.
Tests gave it a B grade: quality 82, process 50. No critical findings, safety 100. But process at half capacity means the description covers scenarios without guaranteeing everything works there. Supported on all major platforms. Install it if you're writing e2e tests for this package and ready to debug isolation and race conditions yourself.

As a process C 50/100 · Has gaps — weak spots: result and completion, inputs and preconditions, running it twice

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.

Process rating: all ten parameters 50/100
- 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
- 30Running it twice. 10 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 50Failures and branches. 0 branches, has a failure section
- 60Tools and files. Uses tools (bash, web, node) that frontmatter does not declare
- 70Execution cost. Instruction body is 4672 tokens
- 100Steps. 101 steps
- 100Consistency. Name and required fields are in place
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
- low The response is described with custom markup (13 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.
