Conciseness

The body is lean throughout: terse numbered instructions, compact executable commands, and short examples, with no explanation of concepts Claude already knows. Every section (Instructions, Examples, When NOT to trigger) earns its tokens, matching the anchor for lean and efficient content.

Actionability

Both commands are copy-paste ready with clearly parameterized placeholders ("caliber skills --query \"<relevant terms>\"" and "caliber skills --install <slug1>,<slug2>"), and the Examples section supplies concrete query strings ("react frontend", "docker deployment", "python machine-learning testing") covering the common cases. This matches the anchor for fully executable guidance with examples covering common cases.

Workflow Clarity

Seven clearly sequenced steps include user-confirmation checkpoints (steps 2 and 4) and implicit verification via reading installed SKILL.md files (step 6). It falls short of anchor 5 because there is no explicit feedback loop for error recovery, e.g. what to do when the query returns nothing useful or an install fails.

Progressive Disclosure

This is a single-file skill with roughly 51 body lines and no bundle files (references/, scripts/, assets/ are absent), yet it is well organized into Instructions, Examples, and When NOT to trigger sections. Per the rubric's guidance for simple skills under 50 lines with no need for external references, well-organized sections alone merit the top score.

Specificity

"Discovers and installs community skills from the public registry" names the domain plus exactly two concrete actions, and the remainder of the description adds trigger guidance rather than further capabilities. This matches the anchor for naming the domain and 1-2 concrete actions without comprehensive coverage; score 4 would require several distinct actions listed.

Completeness

The "what" is explicit ("Discovers and installs community skills from the public registry") and the "when" is explicit with concrete trigger phrases ("Use when the user mentions a technology, framework, or task... asks 'how do I do X', 'find a skill for X', or starts work in a new technology area"). This clearly matches the anchor answering both what and when with concrete trigger phrases; score 4 would require the when to be less explicit.

Trigger Term Quality

Natural user phrases are explicitly quoted ("asks 'how do I do X', 'find a skill for X'") alongside terms like "technology, framework" and "new technology area", giving good keyword coverage. It falls short of comprehensive because common synonyms and concrete variations beyond the two quoted phrases are missing.

Distinctiveness Conflict Risk

Skill-registry discovery is a mostly distinct niche with dedicated triggers, but the phrase "starts work in a new technology area" is broad enough to overlap with many tooling-related skills. It is more distinct than the somewhat-generic anchor 3 but does not have the minimal-conflict precision of anchor 5.
