Conciseness

The body is only a heading and one sentence ('This is the third calendar skill.'), so there is no padding or explanation of concepts Claude already knows. The single sentence merely restates the H1 ('# Calendar (Third)'), a minor redundancy that could be trimmed, matching anchor 4 rather than 5's 'every token earns its place'.

Actionability

'This is the third calendar skill.' only describes; there is no concrete code, command, or executable guidance of any kind. This exactly matches anchor 1 ('only describes rather than instructs') and is not level 2, which requires at least high-level hints toward specific steps.

Workflow Clarity

No steps or sequence are present anywhere in the body — it never states what the skill does or how to do it. The simple-skill exception does not apply because there is no unambiguous single action defined, so this stays at anchor 1 ('steps missing or incoherent') rather than 2, which requires a rough sequence.

Progressive Disclosure

The body has a single heading and no wall of text, no buried or nested references, and no inline content that belongs in separate files. However, it cannot be called a clear, well-organized overview — it signals nothing and points nowhere — so it sits at anchor 3 rather than 4-5, which require demonstrated good structure.

Specificity

'Third calendar skill.' contains no action verbs or concrete capabilities whatsoever — it is a bare label. It matches anchor 1 ('no concrete actions') and falls below anchor 2, whose example ('Processes PDF files') still names an action; 'third' is ordinal filler, not a capability.

Completeness

Neither 'what' nor 'when' is answered: the description never states any capability and has no 'Use when...' clause or equivalent. This matches anchor 1 ('missing both what and when'), and the missing-trigger guidance caps it at 3 regardless — it cannot reach 2 because that requires at least a vague 'what' or a 'when'.

Trigger Term Quality

'calendar' is a relevant, natural keyword a user would actually say, but it is the sole keyword with no variations or synonyms (events, scheduling, dates, .ics). This fits anchor 3 ('some relevant keywords but missing common variations') rather than 2, whose example is a generic term like 'files' rather than a domain-specific one.

Distinctiveness Conflict Risk

By self-describing as the 'third' calendar skill, it guarantees high overlap with sibling calendar skills while providing nothing to distinguish itself. This matches anchor 2 ('very broad; high overlap risk with many similar skills'); it is above anchor 1 only because 'calendar' does narrow the domain.
