Quality

Content

93%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-structured routing skill: concise, command-dense, with an excellent one-level-deep decision tree whose reference targets all exist in the bundle, plus a valuable anti-patterns section covering real failure modes. The only notable gap is the absence of an explicit verify-before-production checkpoint in the deploy workflow.

DimensionReasoningScore

Conciseness

The body is lean throughout: it never explains what Vercel or the CLI is, and every section carries non-obvious operational knowledge (which link type to use, when subdirectories skip prompts, which flag is required in CI). Phrases like 'The build output is ignored' and 'Use VERCEL_TOKEN env var instead of --token' earn their tokens; no padded sections found. This matches 'Lean and efficient; assumes Claude's competence'.

5 / 5

Actionability

Every instruction is a runnable command or a specific file to inspect: 'npm i -g vercel', 'vercel link --repo', 'vercel whoami', 'vercel teams switch', 'vercel curl', and checking '.vercel/project.json' vs '.vercel/repo.json'. The Quick Start block is copy-paste ready with comments distinguishing the single-project and monorepo paths, matching 'Fully executable; copy-paste ready commands'.

5 / 5

Workflow Clarity

Quick Start gives an ordered install→login→link→pull→dev→deploy sequence, and the troubleshooting section provides a genuine feedback loop ('When something goes wrong, check how things are linked first... verify you're on the right team with vercel whoami'). Not 5 because there is no explicit validation checkpoint before the production deploy (e.g. verifying the preview deployment first) — a minor gap for an outward-facing operation.

4 / 5

Progressive Disclosure

The 67-line body is a pure router: a Decision Tree maps every task ('Deploy', 'Domains or DNS', 'Blob storage', 'Monorepos (Turborepo, Nx, workspaces)') to exactly one reference file, and all 16 referenced files exist in references/ at one level deep. This matches 'Clear overview with well-signaled one-level-deep references; easy navigation' — a textbook progressive-disclosure structure.

Description

57%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is concise, concrete about the domain, and highly distinctive thanks to the Vercel name, but it is essentially a 'what' with no trigger guidance and only thin keyword coverage beyond the platform name. Adding a 'Use when...' clause listing common triggers (deploy to Vercel, preview deployments, custom domains, environment variables) would lift both completeness and trigger quality.

Suggestions

Add a 'Use when...' clause with explicit triggers, e.g. 'Use when deploying to Vercel, managing preview/production deployments, custom domains, or Vercel environment variables'.

Replace generic 'manage' and 'develop' with 2-3 concrete actions such as 'manage domains and environment variables, stream logs, run local dev server'.

Include common trigger variations users actually say: 'Vercel CLI', 'vc', 'preview deployment', 'DNS'.

DimensionReasoningScore

Specificity

The description names the domain ('Vercel', 'command line') and one fully concrete action ('Deploy'), but 'manage' and 'develop projects' are generic umbrella verbs with no concrete sub-actions (no mention of domains, env vars, logs, rollbacks, etc.). It matches 'Names domain and 1-2 concrete actions, but not comprehensive'. Not 4 because it doesn't list several specific actions; not 2 because 'Deploy ... from the command line' is a concrete, non-generic action.

3 / 5

Completeness

The 'what' is clearly stated ('Deploy, manage, and develop projects on Vercel from the command line') but there is no 'Use when...' clause or equivalent trigger guidance at all, capping completeness at 3 per the judging guidelines. It is not 2 because the 'what' is concrete and unambiguous, not vague.

3 / 5

Trigger Term Quality

'Vercel', 'deploy', and 'command line' are natural terms a user would say, but common variations are missing: 'CLI', 'vc', 'preview deployment', 'domains', 'environment variables', 'DNS'. This sits at 'Some relevant keywords but missing common variations or synonyms' rather than 4, since users asking about e.g. custom domains or preview URLs would not naturally trigger this wording.

3 / 5

Distinctiveness Conflict Risk

'Vercel' is a highly distinctive platform name that acts as a precise trigger; no other generic skill territory ('projects', 'deploy') would be claimed without the Vercel qualifier. This is a clear niche with minimal conflict risk, matching the top anchor.
