72%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 lean, well-structured orientation skill that respects token budget and delegates detail appropriately to package artifacts. Its weaknesses are an illustrative-only code pattern with undefined variables and the absence of an explicit, validated workflow for the evolve/rollback loop it advertises.
Suggestions
Make the Core Pattern self-contained by defining or sourcing 'llm', 'examples', and 'metric_fn' (e.g., reference a specific complete file under examples/), or show the minimal metric_fn signature so the pattern is copy-paste runnable.
Add a short numbered workflow for the agent-bound evolve loop (attach seed playbook -> run -> collect run-end failure signals -> evolve with verification -> rollback on failure), with an explicit verification checkpoint before persisting the evolved playbook.
Briefly state what 'mine grounded weaknesses' and 'verification' mean operationally (e.g., which method performs verification and what triggers rollback), since these terms currently carry the workflow's safety story without concrete backing.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The 44-line body is lean and entirely package-specific: every line adds facts Claude would not know (Package Facts, the Core Pattern, the API surface, guardrails). There is no padding and no explanation of concepts Claude already knows, matching anchor 5 ('every token earns its place'). | 5 / 5 |
Actionability | The Core Pattern block is concrete Rust but references undefined variables ('llm', 'examples', 'metric_fn') and gives no detail on constructing the metric function or examples format, making it a template rather than executable code (anchor 3: 'missing key details'). The guardrail 'Start from package examples for exact native syntax' partially compensates by pointing to runnable examples, but the inline guidance itself is incomplete, below anchor 4's mostly-executable bar. | 3 / 5 |
Workflow Clarity | A rough sequence is implicit in the When To Use bullets and the Core Pattern (create program, construct playbook, evolve), but the multi-step evolve loop — which the body itself says involves 'verification and exact rollback' — has no explicit step ordering or validation checkpoints. This matches anchor 3 ('sequence present but checkpoints missing or implicit'), not anchor 2 since the tasks are at least enumerated and anchored by code. | 3 / 5 |
Progressive Disclosure | The skill is under 50 lines with no bundle files, and all detail is delegated one level deep to clearly named package artifacts ('API.md', 'axir-api.json', 'axir-capabilities.json', 'examples/') in a dedicated Package Facts section. Per the rubric's simple-skill guidance, this well-organized, cleanly split structure merits anchor 5. | 5 / 5 |
