Quality

Content

22%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 a single self-describing sentence that documents its own deficiencies rather than providing any executable guidance or workflow. It earns a middling conciseness score only because it is short, while failing entirely on actionability and workflow clarity.

Suggestions

Replace the descriptive sentence with concrete, executable instructions (code blocks or specific commands) for the skill's task.

Add a numbered, sequenced workflow with validation checkpoints if the task involves batch or destructive operations.

State the single concrete action the skill performs so a simple skill can satisfy actionability unambiguously.

DimensionReasoningScore

Conciseness

The body is only one sentence and not padded with concepts Claude already knows, so it is lean; however it is terse to the point of conveying no useful instruction, which slightly offsets the token-efficiency benefit.

3 / 5

Actionability

The body 'This skill body lacks ordered steps, imperative verbs, code examples, and guardrails.' only describes what is missing; it provides no concrete code, commands, or executable guidance, matching the entirely-vague anchor.

1 / 5

Workflow Clarity

No steps or sequence are present, and for any risky operation there is no validation; the content explicitly states it lacks ordered steps, matching the missing/incoherent anchor.

1 / 5

Progressive Disclosure

The body has a single section header and no bundle files to reference; for an under-50-line skill with no external references needed, the minimal organization is acceptable, though it signals nothing useful for navigation.

Description

0%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 fails to describe any capability or use case, instead meta-commenting on its own lack of trigger phrases. It matches the lowest anchor on every dimension.

Suggestions

Replace the meta-commentary with concrete third-person actions, e.g. 'Extracts text from PDF files, fills forms, and merges documents.'

Add an explicit 'Use when...' trigger clause naming natural phrases and file extensions a user would mention.

State the specific domain and tools so the skill is distinguishable from adjacent skills.

DimensionReasoningScore

Specificity

The description 'A skill without activation trigger phrases.' names no concrete actions or domain; it is pure abstract meta-commentary about the skill itself rather than describing any capability.

1 / 5

Completeness

Neither 'what it does' nor 'when to use it' is present; the description describes the skill's composition rather than any function, and a 'Use when...' clause is entirely absent.

1 / 5

Trigger Term Quality

No natural keywords a user would say appear; the description contains only the generic word 'skill' and references trigger phrases in the abstract without providing any.

1 / 5

Distinctiveness Conflict Risk

The description is entirely generic and non-functional; it does not distinguish the skill from any other and offers no triggers that would prevent wrong-skill activation.
