Quality

Content

25%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 facade: generic placeholder instructions, duplicated trigger lists, an empty heading, and a link catalog pointing entirely at non-existent files. A reader following any reference fails, and nothing in the body conveys actual data-storytelling technique.

Suggestions

Fix progressive_disclosure first: either add the referenced sub-skills files and resources/implementation-playbook.md to the bundle, or remove the broken links and inline the essential framework/technique guidance directly in SKILL.md.

Replace the boilerplate Instructions ("Apply relevant best practices and validate outcomes") with concrete, domain-specific steps, e.g., how to pick a story framework (problem-solution, trend, comparison), structure an executive summary slide, or write a headline from a chart finding.

Remove the tautological "Do not use this skill when" bullets, the empty "## Core Concepts" heading, and the "Use this skill when" list that duplicates the frontmatter description to reduce token waste.

DimensionReasoningScore

Conciseness

Several sections are pure padding: the tautological "Do not use this skill when" bullets ("The task is unrelated to data storytelling"), an empty "## Core Concepts" heading, and a "Use this skill when" list that duplicates the frontmatter description. This is noticeably below 'mostly efficient' (anchor 3), though it never devolves into explaining concepts Claude already knows (anchor 1).

2 / 5

Actionability

The Instructions are generic boilerplate ("Apply relevant best practices and validate outcomes") with no domain-specific guidance, and the only concrete pointer ("open resources/implementation-playbook.md") targets a file that does not exist. Scored 2 rather than 1 only because the 19 module link titles (e.g., "Framework 1: The Problem-Solution Story", "Headlines That Work") act as high-level hints of what is covered.

2 / 5

Workflow Clarity

A rough sequence exists ("Clarify goals, constraints, and required inputs" → "Apply relevant best practices" → "Provide actionable steps and verification") but the steps are generic and poorly defined, and validation is merely asserted ("validate outcomes") with no checkpoint or feedback loop — matching anchor 2.

2 / 5

Progressive Disclosure

All 20 referenced paths — "resources/implementation-playbook.md" and the 19 "./sub-skills/*.md" links — point to files that do not exist in the bundle, making navigation effectively broken; additionally the "Core Concepts" section is empty and the reference roots are inconsistent ("resources/" vs "./sub-skills/"). The SKILL.md itself has section structure, keeping it above anchor 1.

Description

78%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 well-constructed: third-person voice, explicit 'what' and 'when' clauses, and naturally phrased triggers. Its main weakness is that the capability description stays abstract rather than enumerating concrete actions, and it lacks common trigger synonyms.

DimensionReasoningScore

Specificity

"Transform data into compelling narratives using visualization, context, and persuasive structure" names the domain plus 1-2 actions, but the actions are abstract rather than the several specific, concrete actions of anchor 4; it does more than bare domain naming (anchor 2).

3 / 5

Completeness

Explicitly answers both what ("Transform data into compelling narratives using visualization, context, and persuasive structure") and when ("Use when presenting analytics to stakeholders, creating data reports, or building executive presentations") with concrete trigger phrases, matching the anchor-5 example structure; anchor 4 would require a less explicit 'when' clause.

5 / 5

Trigger Term Quality

"presenting analytics to stakeholders, creating data reports, or building executive presentations" uses natural phrases users would say, but misses common variations such as "dashboards", "quarterly business reviews", and "data-driven insights" — good coverage, not comprehensive.

4 / 5

Distinctiveness Conflict Risk

Data storytelling is a mostly distinct niche, but triggers like "executive presentations" and "data reports" create minor overlap risk with presentation- and dataviz-related skills, so it falls short of anchor 5's minimal conflict risk.
