82%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.
The body is an exemplary lean, executable skill document: two copy-paste-ready commands, a real referenced script, and no wasted tokens. The only gaps are minor — unstated output-directory prerequisite, an unexplained "returned as text" mechanism, and plain-text rather than markdown section headers.
Suggestions
Note that the `out/` directory must be created before redirecting (e.g., `mkdir -p out`), or have the script create it, to keep the examples copy-paste runnable.
Either explain concretely how results are "returned as text" or drop that phrase, and use markdown headers (## Overview, ## Examples) for scannability.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is ~30 lean lines with zero padding and no explanation of concepts Claude already knows; every section (Overview, Examples, Output Files) earns its place. This matches anchor 5 ("Lean and efficient; assumes Claude's competence; every token earns its place"). | 5 / 5 |
Actionability | Both examples are concrete, copy-paste-ready commands (`python3 scripts/fib.py 10 > out/fib.txt` and the stdin-summing heredoc), and scripts/fib.py is a real bundle file. It falls short of anchor 5 because coverage of "common cases" is thin (only two examples for a skill claiming math and text utilities) and minor details are missing, e.g., that the `out/` directory must exist before redirecting output. | 4 / 5 |
Workflow Clarity | As a simple single-action skill, running each example is unambiguous, which supports a high score; however, the overview states "Results can be returned as text and saved as output files" without ever instructing how results are returned, and the Output Files section lists only one file. This places it at anchor 4 ("Clear sequence with most checkpoints present; minor validation gaps") rather than 5. | 4 / 5 |
Progressive Disclosure | The skill is under 50 lines with no need for external references, and its one bundle path (`scripts/fib.py`) is real and clearly signaled one level deep, so structure is appropriate. It misses anchor 5 only on organization polish: section labels ("Overview", "Examples", "Output Files") are plain text rather than markdown headers, making the structure slightly less scannable. | 4 / 5 |
