86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A strong, well-structured body: executable Playwright examples, a sequenced test workflow, and clean two-file progressive disclosure with verified reference targets. The only real cost is spec-knowledge tables (field meanings, readyState values) that re-tread what Claude already knows.
Suggestions
Cut or compress the stream-format field table and the `readyState` 0/1/2 table — Claude already knows this spec detail; keep only non-obvious testing implications (e.g. multiple `data:` line joining, comment-line heartbeats under proxies).
Add a short "when a step's test fails" loop that maps a failing assertion to the anti-patterns table (e.g. events buffered indefinitely → check `\n\n` terminator) to close the workflow-clarity validation gap.
Replace the prose intro paragraph (which restates the description) with a one-line pointer to the WHATWG spec already linked in References.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body assumes SSE knowledge and has no "what is SSE" padding, but the stream-format field table (`data:`/`event:`/`id:`/`retry:` meanings) and the `readyState` 0/1/2 table restate WHATWG spec knowledge Claude already has — minor over-explanation that could be trimmed, matching the 4 rather than the lean 5 anchor. | 4 / 5 |
Actionability | Two complete, copy-paste-ready Playwright tests with real assertions (`expect(transitions).toEqual([0, 1, 2])`), a concrete wire-format example stream, and an anti-patterns table pairing each failure with a specific fix. Covers the common cases fully executably. | 5 / 5 |
Workflow Clarity | A clear sequenced workflow (server-side format → browser test → readyState lifecycle → deeper recipes) where each step embeds assertion-based validation, and the anti-patterns table supplies failure→fix guidance. Not a 5 because there is no explicit validate→fix→retry loop telling Claude what to do when a step's test fails. | 4 / 5 |
Progressive Disclosure | Core tests stay inline while deeper material (reconnect/retry/204/connection-pool recipes, k6 load testing) is split into two real, one-level-deep reference files, each signposted in both a dedicated section and the References list with a description of its contents. Navigation is easy and the split is appropriate. | 5 / 5 |
