common-skill-creator

Standardizes the creation and evaluation of high-density Agent Skills (Claude, Cursor, Windsurf). Ensures skills achieve high Activation (specificity/completeness) and Implementation (conciseness/actionability) scores. Use when: writing or auditing SKILL.md, improving trigger accuracy, or refactoring skills to reduce redundancy and maximize token ROI.

Quality

Content

85%Weight 40%Scale 1-3

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

A dense, well-structured meta-skill with clear sequencing, validation checkpoints, and a verified one-level-deep reference tree. Its main weakness is actionability: several workflow steps are abstract and a couple of lines contain garbled placeholder text that should be fixed.

Suggestions

Repair the garbled fragments, e.g. step 2 'what it , when it trigger' and the 'Drop articles (, , )' line, so each instruction is concrete and parseable.

Tighten abstract workflow steps like 'Iterate — rewrite based on feedback' and 'Research — web-search domain best practices' into specific, executable actions (e.g. name the search queries to run or the iteration directory convention).

De-duplicate the inline reference links and the bottom 'References' section so each file is referenced once with its load condition, reducing redundancy.

DimensionReasoningScore

Conciseness

The body is caveman-compressed and lean ('Close DB connection after query. Prevent leaks.'), avoids explaining concepts Claude already knows, and nearly every line carries procedural value, matching the 'lean and efficient; every token earns its place' anchor; the small garbled fragments are defects, not verbosity, so it stays above the 'could be tightened' anchor at 2.

3 / 3

Actionability

It gives a concrete snapshot command ('cp -r <skill-dir> <workspace>/skill-snapshot/') and specific load triggers, but several steps are abstract ('Iterate — rewrite based on feedback', 'Research — web-search domain best practices') and step 2 is garbled ('what it , when it trigger'), placing it at 'some concrete guidance but incomplete' rather than fully copy-paste ready at 3.

2 / 3

Workflow Clarity

A clearly sequenced 15-step workflow with explicit validation checkpoints (Test at step 4/12, Evaluate at step 5/13), an iterate feedback loop, a pre-edit Snapshot safety step, and a Quality Checklist, matching the 'clear sequence with explicit validation steps; feedback loops; checklists' anchor.

3 / 3

Progressive Disclosure

References are one level deep, each inline link and the References section points to verified-existing files (TEMPLATE.md, eval-workflow.md, etc.), and every reference carries a 'load when' signal, matching the 'clear overview with well-signaled one-level-deep references' anchor.

Description

100%Weight 40%Scale 1-3

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, third-person description that clearly states capabilities and provides an explicit 'Use when' trigger clause with natural keywords. It is distinctive and specific with no over-claims or padding.

DimensionReasoningScore

Specificity

Lists multiple concrete actions in third-person voice ('Standardizes the creation and evaluation', 'Ensures skills achieve high Activation...and Implementation...scores') plus actionable verbs (writing, auditing, improving, refactoring), matching the 'lists multiple specific concrete actions' anchor rather than the partial domain-only anchor at 2.

3 / 3

Completeness

Both 'what' (standardizes creation/evaluation, ensures activation/implementation scores) and an explicit 'when' ('Use when:...') are clearly present, so it is not capped at 2 per the missing-trigger-guidance rule.

3 / 3

Trigger Term Quality

The 'Use when: writing or auditing SKILL.md, improving trigger accuracy, or refactoring skills to reduce redundancy and maximize token ROI' clause uses natural terms a user would say (audit skill, refactor skill, trigger accuracy), giving good coverage rather than the sparse keyword set at level 2.

3 / 3

Distinctiveness Conflict Risk

It targets a clear niche (high-density Agent Skill authoring/auditing, token ROI, trigger accuracy) with distinct triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
