Quality

Content

75%Weight 40%Scale 1-5

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

The content is well-structured, concise, and gives a clear build/iterate workflow with an error-recovery loop. Its main weakness is actionability: it lists and rules the core block files without providing runnable templates for them.

Suggestions

Add minimal copy-paste-ready templates for block.json, edit.js, save.js, and render.php so the core files can be scaffolded directly.

Add an explicit in-skill validation checkpoint (e.g., "verify the block renders in the editor and on the test page") before marking stage: completed, rather than delegating all verification to studio.

Move the per-file guidance (package.json, block.json, PHP bootstrap) into a references file and summarize it in SKILL.md to tighten the overview and improve progressive disclosure.

DimensionReasoningScore

Conciseness

The body is lean, using tight bullets and imperatives, with only minor trimmable lines like "view.js runs on the frontend" and "Keep the package minimal and aligned with the block's actual needs".

4 / 5

Actionability

Concrete paths, build commands ("pnpm exec wp-scripts build"), and the PHP guard snippet are executable, but no copy-paste templates are given for the core block files (block.json, edit.js, save.js, render.php).

4 / 5

Workflow Clarity

A clear numbered workflow plus an explicit error-recovery feedback loop (read error, fix, rebuild, retry up to 3 times, escalate) is present, but final verification is delegated to the studio skill rather than an explicit in-skill checkpoint.

4 / 5

Progressive Disclosure

Sections are well-organized with clear headers and no nested references, but at ~190 lines all guidance is inlined with no bundle files split out, leaving minor organization gaps.

Description

75%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.

The description is specific and well-targeted to a clear niche, but it omits any explicit "Use when…" trigger guidance, which caps completeness. Adding a trigger clause would likely raise both completeness and trigger-term quality.

Suggestions

Append an explicit "Use when…" clause naming natural user triggers (e.g., "Use when the user wants to create or modify a custom Gutenberg block, or mentions a block plugin in a Studio site").

Include a couple of common synonyms/variations users might say ("WordPress block", "Gutenberg block", "block plugin") to broaden trigger-term coverage.

DimensionReasoningScore

Specificity

"Create, edit, build, and review" lists four concrete actions on a named domain ("a custom WordPress Gutenberg block plugin inside a Studio-backed site"), matching the comprehensive multi-action anchor.

5 / 5

Completeness

The description gives a clear "what" but no "Use when…" trigger guidance, so per the judging guideline completeness is capped at 3.

3 / 5

Trigger Term Quality

"WordPress Gutenberg block", "block plugin", and "Studio-backed site" are natural terms users would say, but a few common variations and an explicit trigger phrase are missing.

4 / 5

Distinctiveness Conflict Risk

The Gutenberg-block-in-Studio-site niche is specific with distinct triggers and minimal overlap with other skills.
