92%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 tight, highly actionable skill body: lean prose, concrete CLI/JSON examples, a numbered workflow with explicit stop conditions, a bounded one-retry correction loop, and clean section organization. The only notable gap is that the controller-grab path names its animate/query/verify steps without the actual commands, unlike the fully specified hand-pinch path.
Suggestions
Add the concrete commands for the controller path's animate and query steps (e.g., the `xr run-sequence` or equivalent invocation for `controller-right` approach and the ECS query for `Grabbed`), so steps 4 and 6 are as copy-paste ready as the hand-pinch sequence.
Show a minimal example of how to query the requested observable state (e.g., the CLI command that reads `Grabbed` or the transform) rather than only naming the observable.
Include the expected success signal for the controller squeeze path (analogous to the `selectstart` note for pinch) so a silent failure is diagnosable.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | There is no padding and no explanation of concepts Claude already knows; every line carries project-specific facts (button index 1 vs 0, `grabbing.useHandPinchForGrab` default, `selectstart` semantics, step `position` = object base). It matches the 'lean and efficient; every token earns its place' anchor, not the level-4 anchor which requires some trimmable over-explanation. | 5 / 5 |
Actionability | The hand path is copy-paste ready (full `npx @iwsdk/cli xr run-sequence` with input JSON and `--timeout 45000`) and the squeeze press is given as concrete JSON ("buttons":[{"index":1,"value":1}]), but the controller path's animate/query steps ("Animate the requested controller to the object", "Query the entity for `Grabbed`") name the actions without the corresponding commands. That is 'mostly executable guidance with minor gaps' — the level-5 anchor's full copy-paste coverage of common cases is not quite met. | 4 / 5 |
Workflow Clarity | The numbered sequence has explicit validation checkpoints and a bounded feedback loop: stop-with-evidence if the entity is absent ("list nearby grabbable matches once and stop"), confirm the component type, "If the grab did not qualify, make one focused correction... and retry once", and query the final state after release. This matches the clear-sequence-with-explicit-validation-and-error-recovery anchor. | 5 / 5 |
Progressive Disclosure | The skill is a single ~68-line file with no references/, scripts/, or assets/ bundle; content is organized into three well-labeled sections (Execute the requested path, Hand pinch grab, Evidence and stopping) and nothing is inlined that belongs in a separate file, so navigation is trivial. The single-file layout is appropriate for a skill of this size and purpose, satisfying the well-organized-sections condition. | 5 / 5 |
