Conciseness

The body is dense, opinionated, and assumes Claude's intelligence (no explanations of concepts Claude already knows), but contains real repetition: the visual-companion offer rules appear in three places ('Show, don't tell', the 'Play It Back' pre-send check, and the 'Visual Companion' section) and the build-gate workflow order is stated twice (intro list and HARD-GATE). This matches 'mostly efficient but could be tightened' rather than the minor-trim level of 4.

Actionability

For an instruction-only skill the guidance is copy-paste ready: word budgets ('about 200 words', '200-300 words'), an exact offer script ('This might be easier if I show you. Want me to open a browser tab with some mockups?'), a worked example dialogue (the bakery website question), concrete tables (Size, Red Flags), and an exact output path ('docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md'). Per the rubric's code-vs-instruction note, the absence of code is not penalized.

Workflow Clarity

A clearly sequenced multi-step process (approaches → design doc → approval → writing-plans) with explicit validation checkpoints: the builder check with three-pile triage, the HARD-GATE approval before any building, a feedback loop (one round of 'theirs' questions, doc updated, then handed over), enumerated exceptions (spikes, opt-outs), and growth handling ('If it grows mid-task, stop, say so, and step up a size').

Progressive Disclosure

In-file structure is good — clear section headers, well-signaled one-level-deep references ('read `visual-companion.md` in this directory', 'dispatch a fresh subagent with `builder-check-prompt.md` in this directory') — but scored against the actual bundle, both referenced files are missing (only server scripts/ exist), so navigation fails exactly where content was split out. This sits between the broken/inlined level of 2 and the well-placed level of 4; the good internal organization holds it at 3 while the dangling references block anything higher.

Specificity

Enumerates several concrete trigger activities ("creating features, building components, adding functionality, modifying behavior, or planning anything new") across software and non-software domains, matching the 'several specific actions' anchor. Not 5 because it names only when-conditions, never the skill's own actions, and not 3 because the coverage goes well beyond 1-2 actions.

Completeness

The 'when' is explicit and comprehensive ("MUST use this before any creative work... in software or out of it"), but the 'what' — that the skill runs a questioning conversation, lays out approaches, and produces an approved design doc — is entirely absent, matching the anchor-2 disjunct 'only when is present without what'. Scored 3 rather than 2 because the trigger guidance far exceeds the anchor-2 example's specificity, leaving completeness exactly half-addressed.

Trigger Term Quality

Contains natural phrases users would actually say ("creating features", "modifying behavior", "planning anything new", "a talk, a business, a renovation") with good cross-domain coverage. Not 5 because key synonyms are missing — most notably 'brainstorm' itself, plus 'design', 'prototype', and 'new project'.

Distinctiveness Conflict Risk

"planning anything new, in software or out of it" is very broad and would fire ahead of virtually any creative or building skill, creating high overlap risk (anchor 2). It earns anchor 3 instead because the pre-work gate intent (brainstorm before building, not the building itself) is a genuinely distinct niche with distinct trigger framing.
