The body is largely efficient but includes padding such as the verbatim re-statement of the frontmatter intent, "Why It Matters" rationale columns, and an Origin attribution quote, fitting 'Mostly efficient but includes some unnecessary explanation or could be tightened.' It is not a 1 because the core guidance is useful and not concept-explaining fluff, and not a 3 because several sections could be trimmed without losing clarity.

The skill supplies a complete fill-in template with labeled sections, a quality checklist, specific tools/methods and timelines per prototype flavor, and concrete pass/fail examples, matching 'Fully executable... specific examples; copy-paste ready.' It is not a 2 because the guidance is concrete and complete rather than pseudocode or abstract.

The template provides a sequenced set of fields to fill and the Quality Checklist acts as an explicit validation checkpoint ("If any answer is no, revise your probe or reconsider whether you need one"), matching 'Clear sequence with explicit validation steps... checklists for complex processes.' It is not a 2 because validation feedback is present rather than merely implicit.

The body signals references ("Use template.md", "See examples/sample.md") but those bundle files do not exist, and the full template is inlined anyway, fitting 'references present but not clearly signaled; content that should be separate is inline.' It is not a 1 because sections are organized rather than a monolithic wall, and not a 3 because the one-level-deep references are broken and the inlined template duplicates what template.md would hold.

Quotes "Define a Proof of Life probe to test a risky hypothesis cheaply" name the domain and a couple of actions but do not enumerate multiple concrete capabilities, matching the anchor 'Names domain and some actions, but not comprehensive.' It is not a 1 (vague) because it states a distinct action, and not a 3 because no list of multiple specific actions is given.

The description states both what ("Define a Proof of Life probe to test a risky hypothesis cheaply") and when ("Use when you need harsh truth before building real product") with an explicit trigger, matching the anchor for clearly answering both what AND when.

Phrases like "risky hypothesis", "harsh truth", and "before building real product" are relevant but lean on framework jargon ("Proof of Life probe") that a user may not naturally say, fitting 'Some relevant keywords but missing common variations.' It falls short of 3 due to limited coverage of natural phrasings like 'validate', 'prototype', or 'de-risk'.

"Proof of Life probe" is a clear, niche concept with distinct triggers unlikely to be confused with other skills, matching 'Clear niche with distinct triggers; unlikely to conflict.' It is not a 2 because the domain is sharply bounded rather than merely 'somewhat specific'.
