87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is a tight, highly actionable CLI playbook that externalizes real scripts and stays free of padding. Its main gap is the absence of an explicit validation checkpoint in the capture-to-symbolication workflow.
Suggestions
Insert an explicit validation step between extract and symbolicate, e.g. 'Confirm /tmp/time-sample.xml is non-empty and contains <node> entries before symbolication.'
Add a brief error-recovery loop: if symbolication yields unresolved addresses, re-check the load address via vmmap and confirm the --binary path matches the traced build.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean: numbered CLI commands, short workflow notes, a script listing, and gotchas, with no padding explaining what xctrace or a Time Profiler is; every token earns its place and it assumes Claude's competence. | 3 / 3 |
Actionability | Fully executable, copy-paste-ready commands such as `xcrun xctrace record --template 'Time Profiler' --time-limit 90s ...` and concrete script invocations with arguments provide specific, runnable guidance. | 3 / 3 |
Workflow Clarity | The numbered 1-5 sequence (record, extract, get load address, symbolicate) is clear, and gotchas offer light error recovery, but there is no explicit validation checkpoint (e.g. confirm samples exported non-empty) in the main flow, leaving checkpoints implicit. | 2 / 3 |
Progressive Disclosure | Content is well organized into Quick start, Workflow notes, Included scripts, and Gotchas, with the heavy logic externalized into three real bundled scripts referenced one level deep and clearly signaled. | 3 / 3 |
