68%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.
The body is a focused, well-organized migration reference with concrete mappings and a worked example. Its main weakness is the absence of an explicit verification/feedback loop in the execution workflow for a batch refactor.
Suggestions
Add a final 'Verify' execution step: compile the module, run existing tests, and diff against the original RxJava chain to confirm behavior parity.
Move the detailed operator and subject mapping tables into a bundled references file (e.g. references/mapping-table.md) and link to it from SKILL.md to improve progressive disclosure.
Fill in the example function bodies (or mark them clearly as illustrative stubs) so the before/after snippet is copy-paste ready.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is a dense reference table of concrete type/operator mappings with terse one-liners, efficient overall; a few explanatory glosses ('A single asynchronous value', 'Coroutines Flow natively handles backpressure') could be trimmed but do not amount to the padding seen at 3. | 4 / 5 |
Actionability | Provides concrete type-to-type and operator-to-operator mappings plus a worked before/after Kotlin example and sequenced execution steps, but example bodies use `{ ... }` placeholders rather than fully copy-paste-ready implementations, capping it below 5. | 4 / 5 |
Workflow Clarity | Six numbered Execution Steps give a clear sequence, but there is no validation or verification checkpoint (compile, run tests, diff review) for what is effectively a batch codebase refactor, and the rubric caps such workflows at 3. | 3 / 5 |
Progressive Disclosure | Single-file skill with clear ## sections and no nested references; the detailed operator/subject mapping tables are arguably reference material that could live in a bundled file, which is the minor gap keeping it below 5. | 4 / 5 |
