Conciseness

The two-line body contains zero padding, zero explanations of concepts Claude already knows, and no filler — every token present is directive. Not 4: there are no instances of over-explanation at all to trim.

Actionability

'Follow these snapshot-only instructions' directs Claude to instructions that are never stated anywhere in the body; no concrete code, commands, or specific steps exist. Matches anchor 1 ('entirely vague or abstract; only describes rather than instructs'). Not 2: even a high-level hint of specific executable steps is missing.

Workflow Clarity

No steps or sequence of any kind are present; the only quasi-directive ('Resolve referenced resources relative to this skill directory') points at resources that are not identified. The simple-skill exception does not apply because the single action is not unambiguous — the 'snapshot-only instructions' it says to follow do not exist in the file. Not 2: there is not even a rough sequence with gaps.

Progressive Disclosure

The skill is under 50 lines with no bundle files (no references/, scripts/, or assets/ exist), so the 5-level would require well-organized sections — but the body has no sections or headers, and it contains a dangling directive about 'referenced resources' when none are referenced. Not 4/5: no organization to speak of and a reference pointer with no target; not 2: nothing is inlined that belongs in a separate file, and no deeply nested references exist.

Specificity

The description names its domain ('snapshot tests') and two actions ('project skill discovery and loading'), which is more than the minimal/generic level of 'Processes PDF files' but far short of the several comprehensive actions of a 4 or 5. Not 4: only two thin actions are listed; not 2: the domain is named and the actions, while sparse, are stated.

Completeness

The 'what' is stated ('Exercise project skill discovery and loading in snapshot tests') but there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not 4: the 'when' is entirely absent rather than merely imprecise; not 2: the 'what' is clear, not vague.

Trigger Term Quality

'snapshot tests' is a relevant keyword a maintainer of this test suite might naturally say, but there are no variations or synonyms ('skill discovery', 'skill loading', 'SKILL.md tests') to broaden matching. Not 4: coverage is a single term with several natural phrases missing; not 2: it is more specific than the purely generic 'Works with files'.

Distinctiveness Conflict Risk

The 'snapshot tests' niche is fairly distinct and unlikely to collide with general skills, though adjacent testing skills could overlap. Not 5: the description is too terse to establish a clearly staked-out niche with distinct triggers; not 3: 'snapshot tests' is more specific than the broadly overlapping 'Works with document files'.
