Conciseness

The body assumes Claude's competence — no concept explanations, just commands and decision logic — but repeats the team-selection and "git push else vercel deploy --no-wait" guidance across multiple branches, and the Codex escalation note appears twice (fallback section and Troubleshooting). These are minor instances of over-explanation that cross-referencing could trim, matching anchor 4 rather than the fully lean anchor 5.

Actionability

Every branch gives copy-paste-ready bash (e.g., "vercel deploy [path] -y --no-wait --scope <team-slug>", "npx vercel@latest deploy [path] --temporary -y") with clearly marked placeholders, covering all four environment states. This fully matches the executable, common-cases-covered top anchor.

Workflow Clarity

A clear two-phase sequence (state gathering, then a four-branch decision tree) with explicit checkpoints: user approval before any git push, post-deploy status verification via "vercel inspect"/"vercel ls --format json", and error-recovery loops in Troubleshooting (network failure → escalate, auth failure → --temporary fallback). Deploy/push risks are gated by explicit approval steps, so no cap applies.

Progressive Disclosure

No bundle files exist, and the single-file body is well organized with clear section headers and a navigable decision tree. It is not a 5 because nothing is split out — agent-specific notes and troubleshooting detail could live in one-level-deep reference files to keep SKILL.md a leaner overview.

Specificity

"Deploy applications and websites to Vercel" names the domain and one concrete action, but does not list several specific capabilities (e.g., linking projects, handling auth, preview vs production). It matches the anchor for 1-2 concrete actions without comprehensive coverage, not the several-actions anchor above it.

Completeness

Clearly answers both what ("Deploy applications and websites to Vercel") and when, with an explicit "Use when..." clause containing concrete trigger phrases. This is a direct match for the top anchor; the when-clause rule caps nothing here since explicit triggers are present.

Trigger Term Quality

Four natural verbatim user phrases ("deploy my app", "deploy and give me the link", "push this live", "create a preview deployment") give good keyword coverage. Not a 5 because common synonyms like "publish", "ship it", or "go live" are missing.

Distinctiveness Conflict Risk

A clear niche (Vercel deployment) with platform-named, distinct triggers makes conflict with other skills minimal. Only negligible overlap risk exists with other deployment-target skills, which the explicit "Vercel" naming resolves.
