Conciseness

The body restates the pyramid/MECE/SCQA framework in the Overview, again in Steps 3-4, and again in the Anti-patterns table; the Wikipedia quote ("can't derive an idea from a grouping unless the ideas in the grouping are logically the same") appears in both the Overview and Step 4, and the book citation with ISBN appears in the frontmatter and again in References. This is mostly efficient prose with some unnecessary repetition that could be tightened - the anchor-3 fit - rather than anchor-2 padding (the bulk is tight tables and numbered steps) or anchor-4 leanness (the duplicated quotes and citations across three sections are more than minor).

Actionability

For an instruction-only skill the guidance is concrete and executable: a Step 1 input table with sources and roles, a halt condition 'Halt with UNCITED_INPUTS if the supplied numbers carry no source artifacts', worked SCQA example sentences ('We ship weekly to 40k customers...', 'Q2 doubled deployment frequency while QA headcount was flat.'), a named grouping taxonomy ('outcomes ... delivery ... commitments ... capacity/risk'), and a fenced output template. It falls short of anchor 5 only in minor gaps: the Step 5 template is a compressed one-line skeleton ('## 1. Outcomes ... ## 2. Delivery ...') and the citation format is demonstrated only in the external reference, not in the body; it is well above anchor 3 because real example sentences, a halt code, and a template replace pseudocode.

Workflow Clarity

Five numbered steps in a clear sequence with explicit validation checkpoints and a feedback loop: Step 1 halts on 'UNCITED_INPUTS' when 'the supplied numbers carry no source artifacts'; Step 3 prescribes error recovery - 'If it cannot be written, the analysis is not done; go back to the inputs, not to the slide deck'; Step 4 gives an explicit grouping check ('headers that do not overlap and jointly cover the story'); and the Anti-patterns table maps each failure mode to its fix, functioning as a checklist. This matches the top anchor (clear sequence, explicit validation, feedback loops for error recovery); a 4 would require a missing checkpoint, and none is missing.

Progressive Disclosure

The bundle verifies: references/dora-metrics.md (27 lines) and references/qbr-narrative-example.md (38 lines) both exist, are referenced from the body with purpose signals ('the verbatim definitions are in [references/dora-metrics.md]', 'See [references/qbr-narrative-example.md] for the fully worked QBR narrative with real numbers and their sources'), and are one level deep - neither points onward to further skill files. The split is appropriate: verbatim DORA definitions and the worked example live in references while the workflow stays in the ~95-line body, matching the top anchor (clear overview, well-signaled one-level-deep references, easy navigation).

Specificity

Quotes several concrete actions - 'turns already-computed quality data - weekly digests, KPI roll-ups, DORA delivery metrics, escape-defect trends, OKR grading - into an executive or QBR narrative' with 'governing answer first, MECE-grouped support beneath it, SCQA opening' - which matches the anchor for several specific actions with minor gaps. It is not a 5 because the action list covers only the structuring transformation (internal behaviors like the UNCITED_INPUTS halt and DORA vocabulary rules are absent), and well above a 3 because the enumerated inputs and structural devices go beyond 1-2 concrete actions.

Completeness

Explicitly answers both questions: what - 'turns already-computed quality data ... into an executive or QBR narrative structured by the Minto Pyramid Principle' - and when - 'Use before a QBR, board update, or exec review when the data exists but the story does not.' The when-clause carries concrete trigger phrases and the voice is third person ('turns'), matching the top anchor exactly; a 4 would require the when to be less explicit than it is.

Trigger Term Quality

Natural terms a user would say are well covered: 'QBR', 'board update', 'exec review', 'executive ... narrative', 'weekly digests', 'KPI roll-ups', 'DORA delivery metrics', 'escape-defect trends', 'OKR grading'. Not a 5 because common synonyms are missing - 'quarterly business review' is never spelled out, and phrases like 'executive summary', 'leadership update', or 'quality report' are absent; well above a 3 since coverage extends past a couple of generic keywords into the user's natural vocabulary.

Distinctiveness Conflict Risk

The description proactively fences off the three neighboring skills - 'Distinct from single-team digest computation ... from portfolio-review aggregation ... and from QA OKR authoring' - and carves a clear niche as the communication layer that 'consumes such digests and writes the upward story'. This is a clear niche with distinct triggers and minimal conflict risk, matching the top anchor; nothing in it would plausibly trigger the wrong skill.
