82%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.
Highly actionable, executable guidance with a clear authoring sequence, a useful anti-patterns table, and honest limitations. Minor gains are available from removing the duplicated doc link and adding an explicit failure-handling note.
Suggestions
Drop the duplicated 'launchdarkly.com/docs/sdk' link from References (it is already cited in Overview) to tighten token usage.
Add a short troubleshooting note for the failure mode the anti-patterns hint at — e.g., 'if variation returns the default, confirm waitForInitialization() resolved and td.update() ran before the assertion' — to create an explicit feedback loop.
Clarify that the percentage-rollout example asserts determinism, not a specific bucketing outcome, so readers don't copy it expecting a 50/50 split.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly lean and code-forward — it assumes competence and never explains what feature flags are — but 'References' repeats the launchdarkly.com/docs/sdk link already cited in Overview, and phrases like 'the canonical hermetic-test pattern' could be trimmed. Not 5 due to that duplication; not 3 since there is no genuine over-explanation or padding. | 4 / 5 |
Actionability | Copy-paste-ready TypeScript throughout: 'LaunchDarkly.TestData.dataSource()', 'td.update(td.flag("show-new-ui").booleanFlag().on(true))', 'await client.waitForInitialization()', teardown via 'afterAll', and a CI yaml snippet — covering the common cases (flag on/off, per-user targeting, deterministic rollout, file fixtures). Not 4: there are no material gaps in executability. | 5 / 5 |
Workflow Clarity | Clear Install → Initialize → author tests → Teardown sequence with explicit checkpoints ('Always update first', 'Always wait', 'client.close() in afterAll') plus an anti-patterns table that works as a checklist. Not 5: there is no explicit error-recovery feedback loop (e.g., what to do when a variation unexpectedly returns the default). | 4 / 5 |
Progressive Disclosure | Well-organized single file (~180 lines) with clearly signaled external references (LD docs links, sibling skills 'openfeature-sdk-testing', 'feature-flag-test-harness', 'ab-test-validity-checklist'); no bundle files exist, and nothing that belongs in a separate file is inlined. Not 5: all depth lives in this one file with external doc links as the only escape hatch, and the skill is over the ~50-line simple-skill threshold. | 4 / 5 |
