protected-vercel-deployments

Access and test Vercel deployments protected by Vercel Authentication, SSO, or Deployment Protection with agent-browser. Use when a preview or production URL redirects to a Vercel login page, returns a protection 401 or 403, or needs short-lived Trusted Sources OIDC authentication instead of a static bypass secret or public exception.

Quality

Content

88%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.

The body is lean, highly actionable, and well-sequenced with validation and error-recovery guidance for an access-control-sensitive workflow. Its only soft spots are minor cross-section redundancy and a single-file structure that, while appropriate, offers no progressive references.

Suggestions

Consolidate the credential-handling warnings so 'Never print the token' and the 'Avoid dead ends' bullet on exposing tokens do not repeat the same guidance.

If the Static-secret fallback or Other-environments sections grow, consider splitting them into a reference file and signaling it from the main body to strengthen progressive disclosure.

DimensionReasoningScore

Conciseness

Dense and high-signal content that assumes Claude's competence and avoids explaining basics, with only minor redundancy (e.g. 'Never print the token' repeated near 'Avoid dead ends') that could be trimmed.

4 / 5

Actionability

Multiple complete, copy-paste-ready bash blocks (vc whoami/--version, vc project token, agent-browser open with injected header, agent-browser snapshot, vc project protection enable) cover the common cases fully.

5 / 5

Workflow Clarity

Clear sequenced workflow with explicit validation checkpoints (CLI >=53.3.0 gate, 'test -n "$TOKEN"'), a feedback loop (Diagnose failures mapping each symptom to a cause), and a checklist (Human intervention boundaries) for the access-control-sensitive steps.

5 / 5

Progressive Disclosure

Well-organized single file with clear section headers and no bloated content needing extraction, but it exceeds the simple-skill line and carries no one-level-deep references, so it sits just below the reference-anchored 5.

Description

87%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 specific, complete, and clearly distinct, with concrete 'what' and 'when' guidance tied to recognizable Vercel protection failure modes. It is slightly held back on specificity and trigger-term breadth by relying on only two primary verbs and limited synonyms.

DimensionReasoningScore

Specificity

Names the domain and concrete actions ('Access and test Vercel deployments protected by Vercel Authentication, SSO, or Deployment Protection') with comprehensive protection-type coverage, though only two primary verbs ('access', 'test') keeps it just below the multiple-distinct-actions bar for a 5.

4 / 5

Completeness

Explicitly answers both 'what' (Access and test protected deployments with agent-browser) and 'when' (Use when a URL redirects to a Vercel login page, returns 401/403, or needs short-lived Trusted Sources OIDC) with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural triggers a developer would hit ('preview or production URL redirects to a Vercel login page', 'returns a protection 401 or 403') are present and well-matched to the use case, but synonym coverage is not exhaustive.

4 / 5

Distinctiveness Conflict Risk

A clear narrow niche (Vercel protected deployments via short-lived Trusted Sources OIDC with agent-browser) with distinct, specific triggers and minimal overlap with other skills.
