Quality

Content

86%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 body is an exemplary instruction-only skill: token-efficient, structured around core principles, and anchored by a copy-paste frontmatter schema and a concrete writing workflow. Main improvement opportunities are adding a worked example of a good description and a post-creation validation checkpoint.

DimensionReasoningScore

Conciseness

Lean and efficient throughout: the 'What a skill is' section conveys platform-specific mechanics (only name+description in the system prompt, read_skill fetching, persona exclusion) rather than general knowledge, and every section earns its tokens. No trimmable over-explanation found.

5 / 5

Actionability

Mostly executable guidance: a copy-paste frontmatter template with field constraints, the read_skill(name, file=...) call syntax, the trigger test, the exact question to ask users, and the UI path (Space → Skills). Minor gaps: no worked example of a good/bad description line, and directives like 'tighten what the model stumbled over' remain abstract.

4 / 5

Workflow Clarity

The 5-step writing workflow is clearly sequenced with an explicit checkpoint (step 3: verify the description passes the trigger test) and an iteration loop (step 5). Not 5: no checkpoint verifying the created skill actually fires before shipping; not 3: checkpoints are explicit and no destructive/batch operations apply.

4 / 5

Progressive Disclosure

Well-organized sections (What/Anatomy/Principles/Workflow), ~77 lines with no external files needed, a one-level-deep reference model, and explicit guidance on when to move content into references/ — clear navigation with no monolith or nesting problems.

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 description with an explicit 'Use when' trigger clause and clear what/when separation in third person. Trigger phrases are natural and distinct; the only weakness is that the stated capability list ('design and author') is thinner than the trigger enumeration suggests.

Suggestions

Enumerate a couple more concrete capability actions in the what-clause (e.g., 'Design, author, and review DeepTutor skills') so stated capabilities match the trigger coverage.

Add natural synonyms users might say, such as 'write a skill', 'edit a skill', or 'SKILL.md', to broaden trigger term coverage.

DimensionReasoningScore

Specificity

Names the domain ('DeepTutor skills (SKILL.md packages)') with two concrete action verbs ('Design and author'), matching the '1-2 concrete actions, not comprehensive' anchor. The create/improve/explain mentions are trigger conditions rather than stated capabilities, so the several-specific-actions anchor (4) is not met.

3 / 5

Completeness

Explicitly answers both: what ('Design and author DeepTutor skills (SKILL.md packages)') and when ('Use when the user wants to create a new skill, improve an existing skill, or asks how skills work') with concrete trigger phrases — the anchor-5 pattern.

5 / 5

Trigger Term Quality

Natural user phrases — 'create a new skill', 'improve an existing skill', 'asks how skills work' — give good coverage with concrete triggers. Missing a few natural synonyms ('write a skill', 'edit a skill', 'SKILL.md'), so it falls short of the comprehensive anchor (5).

4 / 5

Distinctiveness Conflict Risk

Skill authoring is a clear niche with distinct triggers; sibling skills (code, document, data skills) would not match these triggers, so conflict risk is minimal.
