87%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A concise, highly actionable reference skill with clean structure and well-signaled pointers to package docs, weakened only by an implicit rather than explicitly sequenced usage-observer workflow.
Suggestions
Add a short numbered sequence for centralized usage accounting (register observer -> attach usageContext per call -> enqueue synchronously -> persist out-of-band -> clear on teardown) so the multi-step setup has an explicit order.
Include a validation/verification checkpoint in that workflow, e.g. how to confirm the observer is wired (emit a test event and assert the queue receives it) before relying on it in production.
Note the failure-mode feedback loop explicitly: what to check when an expected usage event does not arrive (unconsumed/cancelled stream), so Claude can diagnose rather than assume success.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and axllm-specific — every bullet encodes package behavior Claude would not already know (e.g., "The observer is process-wide, best-effort, and fail-open") with no generic concept explanations, matching the score-3 anchor; it does not include the unnecessary library-introduction padding that would drop it to 2. | 3 / 3 |
Actionability | It provides executable Rust (the `agent(...).forward(...)` core pattern and the `set_usage_observer` snippet), concrete file paths (`API.md`, `axir-api.json`, `src/examples/rust/generation/usage_observer.rs`), and a specific API surface list, hitting the copy-paste-ready score-3 anchor rather than the pseudocode score-2 anchor. | 3 / 3 |
Workflow Clarity | Sections are well-organized and "When To Use" + "Core Pattern" are clear, but the multi-faceted usage-accounting setup is spread across bullets (register observer, attach context, clear on teardown, persist out-of-band) without an explicit ordered sequence or validation checkpoints, fitting the score-2 anchor of steps present but checkpoints implicit; it lacks the validate→fix→retry loop needed for score 3. | 2 / 3 |
Progressive Disclosure | The SKILL.md functions as a concise overview with clearly signaled one-level-deep references to detailed material (Package Facts points to `API.md`, `axir-api.json`, `examples/`), with no nested/deep references, matching the score-3 anchor; the inline API surface list is a compact discovery aid, not the 200-line monolithic block described in the score-2 anchor. | 3 / 3 |
