Conciseness

Lean and efficient — every line earns its place, no concept explanations Claude already knows, and the closing directive ('Run the command yourself') adds genuine non-obvious value.

Actionability

Provides the exact executable command 'plannotator annotate <path-or-url>' and a concrete numbered behavior sequence — copy-paste ready with no pseudocode.

Workflow Clarity

Clear four-step sequence (launch → wait → address annotations / report no feedback → continue) that is unambiguous; as a simple single-task skill it qualifies for the maximum even without a validation feedback loop.

Progressive Disclosure

Under 50 lines with no bundle files and no external references; content is well-organized into clear sections (command, behavior list, directive), satisfying the simple-skill exception.

Specificity

Names two concrete actions ("Open Plannotator's annotation UI", "respond to the returned annotations") and enumerates specific file types (.yaml, .json, .toml, .ini, .csv, .log), HTML, URL, and folder — listing multiple specific concrete actions.

Completeness

Clearly answers "what does this do" but the "when to use it" guidance is only implied; there is no explicit "Use when..." clause, which caps completeness at 2 per the rubric guidelines.

Trigger Term Quality

Covers natural terms a user would say — "markdown file", "HTML file", "URL", "folder", and the enumerated config-file extensions — giving good coverage of likely user phrasings.

Distinctiveness Conflict Risk

Names a distinct niche (Plannotator's annotation UI) with specific triggers (file types, URL, folder), making it unlikely to fire for the wrong skill.
