33%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is well-organized and reasonably scoped, and the when-to-use / when-not-to-use guidance is genuinely useful. However, it describes positioning instead of instructing how to do it: the actual canvas, its components, and the step sequence of Dunford's framework are entirely absent, leaving Claude with no executable path from trigger to deliverable.
Suggestions
Add a numbered, sequenced procedure for running the positioning exercise (e.g., competitive alternatives → unique attributes → differentiated value → target customers → market category), with validation checkpoints such as confirming real evidence backs each claimed attribute before locking the category.
Include the canvas itself — the component definitions, the discovery questions to ask the user, and one filled-in example — so the skill instructs rather than only describes; this is the single biggest gap given the skill is named after the canvas.
Delete the "Domain Context" and "Input Requirements" boilerplate sections, which contain no positioning-specific information and re-explain things Claude already knows.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | "This skill implements a proven product management framework. The approach combines best practices from industry leaders..." and the generic "Input Requirements" section are filler that add no positioning-specific information, and "What It Is" re-explains positioning basics Claude already knows. The majority of sections (When to Use / When Not to Use, Resources) are reasonably efficient, so this sits at mostly-efficient-with-some-unnecessary-explanation rather than noticeably verbose. | 3 / 5 |
Actionability | Despite the skill being named "Positioning Canvas", the body never presents the canvas, its components, questions to ask, or any steps to execute — only "Define or refine how you compete" style high-level hints plus useful but non-procedural when/when-not-to-use lists. This matches 'minimal concrete guidance; high-level hints but missing the specific steps to execute'; not a 1 because the When Not to Use criteria and use-case list are concrete decision guidance. | 2 / 5 |
Workflow Clarity | No multi-step sequence exists anywhere in the body — running a positioning exercise inherently requires ordered steps (alternatives → attributes → value → customers → category) and none are presented, nor any validation checkpoints. This matches 'steps missing or incoherent; no sequence'; a 2 would require at least a rough sequence, which is absent. | 1 / 5 |
Progressive Disclosure | The body is well-organized with clear section headers, no bulk reference material inlined, and a clearly labeled one-level external link in "Further Reading". Not a 5: the body exceeds the simple-skill threshold (~63 lines), uses inconsistent heading hierarchy (## sections before the # title), and the framework detail that should live in a bundled reference is simply missing rather than split out. | 4 / 5 |
