screenshot-camera

Capture a screenshot from a Unity `Camera` and return it as a PNG image for direct LLM inspection. Falls back to `Camera.main` (then any active camera) when `cameraRef` is null. Width and height are capped to keep response size manageable.

Quality

Content

77%

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

The body is actionable with a clear single-task workflow and good sectioning, but loses conciseness to triplicated input definitions and has no progressive-disclosure structure for the sizable inline schema.

Suggestions

De-duplicate inputs: keep either the prose Inputs section or the Input table, not both, and avoid restating them a third time in the body.

Move the verbose input JSON schema (GameObjectRef definitions) into a references file and link to it, keeping SKILL.md as a lean overview.

Replace the placeholder '--input {"width": 0, "height": 0}' with realistic example values that reflect the documented defaults.

DimensionReasoningScore

Conciseness

Mostly efficient but redundant — inputs appear as a prose '## Inputs' section, again as an '## Input' table, and again in the inline JSON schema — so it could be tightened rather than being fully lean.

2 / 3

Actionability

Provides fully executable, copy-paste-ready CLI commands plus stdin/file variants and a complete input JSON schema, matching the executable-examples anchor.

3 / 3

Workflow Clarity

For this single simple task the Behavior section sequences the operation unambiguously (allocate RenderTexture, swap, Camera.Render, ReadPixels, encode PNG, restore), so per the simple-skills note workflow clarity is clear.

3 / 3

Progressive Disclosure

Sections are well organized with no nested references, but the large inline JSON schema and duplicated input table could be split into reference files and there is no progressive-disclosure navigation pointing to detail materials.

Description

67%

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

The description is specific and distinctive but lacks an explicit 'when to use' trigger clause, capping completeness. Trigger terms are natural but could cover more common variations.

Suggestions

Add an explicit 'Use when...' clause naming when Claude should invoke this skill (e.g., 'Use when the user asks to capture or view what a Unity camera sees, or needs a screenshot of the current scene').

Broaden trigger terms with common phrasings like 'screen capture' or 'frame grab' alongside 'screenshot'.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Capture a screenshot from a Unity Camera and return it as a PNG image', 'Falls back to Camera.main (then any active camera)', and 'Width and height are capped' — matching the multiple-specific-actions anchor.

3 / 3

Completeness

It clearly states what the skill does but has no explicit 'Use when...' trigger clause, which per the judging guidelines caps completeness at 2.

2 / 3

Trigger Term Quality

Contains natural terms like 'screenshot', 'Camera', and 'PNG image' that users would say, but misses common variations such as 'screen capture' or 'frame grab', so it is not full coverage.

2 / 3

Distinctiveness Conflict Risk

The Unity Camera screenshot niche with distinct triggers is clearly distinguishable and unlikely to fire for the wrong skill.
