75%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 well-structured, code-dense skill that is easy to follow end to end, with concrete executable examples at every step and an honest Limitations section. The consistent gap is polish rather than substance: a redundant definitional opener, a few missing imports/undefined placeholders in examples, and no explicit feedback loops for what to do when the checks fail.
Suggestions
Delete the two-line opening that defines what a deadlock is (thread A holds X waiting for Y...) — Claude already knows this; start at 'When to use'.
Close the small executability gaps: drop the 'rough sketch' hedge in Step 2, add `import time` to the Step 5 test, and note explicitly that run_workload/run_workload_capture are placeholders for the user's own workload harness.
Add a short feedback loop after Steps 4 and 8 telling the reader what to do on failure — e.g., 'on cycle: identify the offending acquire site from the path output, align it with the Step 1 order, and re-run the workload capture to confirm.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: terse step framing ("Any cycle = potential deadlock under the right scheduling.") backed by code that earns its tokens. Minor over-explanation exists, e.g., the opening definition "A deadlock = a cycle in the lock-wait graph: thread A holds X waiting for Y; thread B holds Y waiting for X" re-teaches a concept Claude already knows. | 4 / 5 |
Actionability | Mostly executable guidance: the OrderedLock instrumentation, graph builder, DFS cycle finder, timeout test, and jstack/TSAN_OPTIONS commands are concrete and runnable. Minor gaps: Step 2 self-describes as a "rough sketch", Step 5's test omits the `time` import, and Steps 4/8 rely on undefined placeholders (`run_workload_capture()`, `run_workload()`). | 4 / 5 |
Workflow Clarity | Eight clearly numbered steps proceed logically from prevention (convention, instrumentation) to detection (graph, cycles, timeout, TSan) to response (postmortem, fingerprint), and each test's assert serves as a validation checkpoint. Not a 5 because there are no explicit feedback loops — e.g., what to do when Step 4 reports a cycle or which step to revisit when the fingerprint count exceeds 5 is left implicit rather than stated as a validate-and-retry path. | 4 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/), so all content is inline; at ~230 lines it stays navigable via clear `## Step N` headers plus Anti-patterns, Limitations, and References sections. The References section is one level deep (TSan docs URL, sibling skill pointers). Slightly below 5 because the per-language instrumentation and postmortem command details could live in reference files to slim the main body. | 4 / 5 |
