Conciseness

The body is compact (~43 lines) and explains nothing Claude already knows, but the Key Features section carries promotional padding ("Verified: 82KB → 20KB per BUILD load", "5-step forced reasoning for Opus-level quality from Sonnet") that could be tightened into factual statements. Mostly efficient with some unnecessary marketing content.

Actionability

Install commands are executable ("npx @smorky85/aurakit", git clone + install.sh) and Usage shows real /aura invocations, but the actual operational guidance is missing: no mode definitions, no description of what Claude should do when /aura is invoked, and no configuration steps for the "13 runtime hooks". Concrete guidance exists but key details are absent.

Workflow Clarity

There is a rough sequence (install → invoke commands) but the workflow after invocation is entirely undefined — what a BUILD, FIX, or REVIEW mode actually does and in what order is never stated. The simple-skill exception does not apply because the single action is ambiguous, not unambiguous.

Progressive Disclosure

The skill is under 50 lines with no external reference files needed (references/, scripts/, assets/ are absent), and the content is organized into clear, well-labeled sections (Overview, Key Features, Install, Usage, Links) with outbound links properly isolated in a Links section. This fits the simple-skill guideline of scoring 5 on well-organized sections alone.

Specificity

The description names the domain ("fullstack engine") and specific feature counts ("34 modes, SEC-01~15 OWASP security, 13 runtime hooks"), but lists no concrete actions a developer would take. It reads as a feature manifest rather than a capability statement, matching the 'names the domain but actions are minimal or generic' anchor.

Completeness

The 'what' is only vaguely conveyed through branded feature counts, and there is no 'when' guidance at all — no 'Use when...' clause or equivalent trigger context. This matches 'has a vague what and no when', and the missing trigger clause caps completeness at 3 regardless.

Trigger Term Quality

Phrases like "Sonnet Amplified fullstack engine", "SEC-01~15 OWASP security", and "75% token reduction" are marketing jargon and statistics, not natural keywords a user would say when needing this skill (e.g., 'build this feature', 'fix this bug', 'review my code'). No natural trigger terms appear anywhere.

Distinctiveness Conflict Risk

"Fullstack development engine" is very broad and would overlap with nearly any development, build, fix, review, or deploy skill. Only the brand name 'aurakit' is distinctive, and brand names are not trigger terms users naturally say.
