image-resize

Use this skill when the task involves resizing, scaling, or compressing image files. Suitable for tasks like "resize these photos to 800px wide", "compress images to reduce file size", or "batch scale all JPEGs in a folder". Only relevant for image processing tasks — do NOT use for data files, text, or non-image tasks.

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A clean, minimal body that points to an executable script with a copy-paste example. Its weaknesses are the missing batch-verification step and incomplete coverage of the script's options (height, compression).

Suggestions

Add a verification step after the batch run (e.g., list output files or check dimensions) to satisfy batch-operation workflow expectations.

Show the --height flag and a compression/format example to match the capabilities advertised in the description.

Dimension	Reasoning	Score
Conciseness	Lean and efficient: a one-line summary, a single script pointer, and one copy-paste command with no padding or explanation of concepts Claude already knows.	5 / 5
Actionability	Provides a concrete, executable command referencing a real script, but only demonstrates the width-resize case; --height and the advertised compression are not shown.	4 / 5
Workflow Clarity	The single-command sequence is unambiguous, but this is a batch operation with no validation/verification step (e.g., confirm outputs or dimensions), which caps workflow clarity at 3 per the batch-operation rule.	3 / 5
Progressive Disclosure	Well under 50 lines with well-organized sections (Available Scripts, Usage) and a one-level reference to the real scripts/resize.py file, fitting the simple-skill exception.	5 / 5
	Total	17 / 20 Passed

Description

82%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-scoped description with clear trigger phrases and an explicit non-use clause. The main weakness is second-person voice and slight redundancy between resize/scale, which caps specificity.

Suggestions

Rewrite in third person (e.g., "Resizes, scales, and compresses image files") to avoid the second-person specificity penalty.

Differentiate resize vs. scale or add a distinct action (e.g., crop or convert format) to broaden capability coverage.

Dimension	Reasoning	Score
Specificity	Names concrete actions ("resizing, scaling, or compressing image files") with several example tasks, but resize/scale are near-synonyms leaving minor coverage gaps; reduced by 1 for second-person voice ("Use this skill").	3 / 5
Completeness	Explicitly answers both what (resize/scale/compress image files) and when ("Use this skill when the task involves..." with concrete example triggers and an exclusion clause).	5 / 5
Trigger Term Quality	Includes natural phrases users would say ("resize these photos to 800px wide", "compress images to reduce file size", "batch scale all JPEGs"), though file extensions like .jpg/.png are absent.	4 / 5
Distinctiveness Conflict Risk	Clear image-processing niche with an explicit exclusion ("do NOT use for data files, text, or non-image tasks"), minimizing overlap with other skills.	5 / 5
