Conciseness

The body is lean — a pipeline diagram, terse per-step 'Provide / Wait for / Read' directives, and compact markdown templates — with no explanatory padding of concepts Claude already knows, matching the score-3 'lean and efficient; every token earns its place' anchor.

Actionability

It gives concrete executable guidance: exact progress file paths, what to provide and wait for at each stage, full markdown templates with named fields, and an explicit gate ('Do not proceed if the target or assumptions are undefined'), matching the score-3 'fully executable; copy-paste ready' anchor rather than the pseudocode-level score-2 example.

Workflow Clarity

The seven steps are clearly sequenced with explicit validation checkpoints (PASS/FAIL status fields, the Step 0 gating rule, and a dedicated quality-audit step that checks prior stages), matching the score-3 anchor for clear sequence plus explicit validation and checklists; it is not a 2 because checkpoints are explicit rather than implicit.

Progressive Disclosure

No bundle files exist (references/scripts/assets are absent) and the single SKILL.md is well-organized into Overview, Pipeline, per-step Workflow, Progress File Specification, and Key Conventions sections; per the rubric's simple-skill note, well-organized sections with no need for external references can score 3, so this is not the disorganized score-2 case.

Specificity

The description lists multiple specific concrete actions ('formal problem formulation, method proposal, theoretical analysis, experimental evaluation, comparison, and final result synthesis'), matching the score-3 anchor for enumerating several distinct concrete actions rather than vague language.

Completeness

It clearly answers 'what' (the full pipeline of stages) but provides no explicit 'when'/'Use when...' guidance, and the rubric caps completeness at 2 when trigger guidance is missing; it is not a 1 because the 'what' is strong and specific.

Trigger Term Quality

The description relies on technical pipeline jargon ('orchestrate', 'theoretical analysis', 'result synthesis') and omits the natural trigger terms a user would actually say, which appear only in metadata.trigger-keywords rather than the description; it is not below 2 because the named stages are domain-relevant, but it lacks common natural variations for a 3.

Distinctiveness Conflict Risk

The niche is clear and specific — a statistical research pipeline requiring formal formulation and theory — making it unlikely to trigger for unrelated skills; it matches the score-3 'clear niche with distinct triggers' anchor rather than the overlapping score-2 example.
