Conciseness

The body is very lean (~4 lines) and explains nothing Claude already knows, matching 'efficient; assumes competence'. It falls short of 5 because the opening line "Based on a plan make an implementation:" is redundant with the heading and description, and "You must add follow the plan" is garbled and could be trimmed to a clean directive.

Actionability

Guidance is high-level only: "follow the plan, and read research if you have questions" and "Make a test for every section... using pytest" give no commands, code, examples, or specifics (e.g., how to run pytest, what a test per section looks like). This matches 'minimal concrete guidance; high-level hints but missing the specific steps'; it is above 1 only because pytest and the per-section test rule are semi-concrete.

Workflow Clarity

The two bullets give only a rough sequence with large gaps: no ordering of implement -> test -> run -> fix, and no validation checkpoint (tests are to be written but nothing says to run them and iterate on failures). This matches 'rough sequence present but many gaps; validation absent'; not 3 because even the step list itself is incomplete and incoherent ('You must add follow the plan').

Progressive Disclosure

As a sub-50-line simple skill with no bundle files (no references/, scripts/, or assets/ exist), well-organized short content can score highly, and nothing here needs splitting out. It is not 5 because the instruction to "read research if you have questions" points at a resource that is neither part of the skill nor clearly signaled, leaving minor navigation/organization gaps.

Specificity

"Create an implementation based on a plan" names a domain (implementation from a plan) with one minimal, generic action verb; there is no listing of what the implementation involves. It sits between the vague anchor 1 and the '1-2 concrete actions' anchor 3, and below it because 'create an implementation' is not a concrete, specific action.

Completeness

There is a clear 'what' ("Create an implementation based on a plan") but no 'when' / 'Use when...' clause at all, which per the guidelines caps completeness at 3. It is not a 4 because nothing implies or states when the skill should be invoked.

Trigger Term Quality

The only candidate keywords are "implementation" and "plan" — one or two generic terms with no natural phrases or variations a user would say (e.g., "implement the plan", "write the code from the plan", "build from spec"). This matches anchor 2; it is above anchor 1 only because the terms are at least domain-relevant rather than jargon.

Distinctiveness Conflict Risk

"Create an implementation based on a plan" is very broad and would overlap with virtually any coding or implementation skill; nothing distinguishes it. It is above anchor 1 only because it is scoped to plan-following rather than being doubly generic.
