90%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is an exemplar of lean, executable skill writing: concrete commands for both HTTP and browser paths, correct security posture (never print/persist the token, do not disable protection, obtain authorization for access-control changes), and useful error-recovery guidance. The only structural gaps are the absence of an explicit ordered decision flow and the lack of any progressive-disclosure layer if the skill expands.
Suggestions
Add a short ordered decision flow at the top (e.g., 1. HTTP request → use `vc curl`; 2. Browser automation → attach the OIDC header; 3. On failure → Diagnose section) to give the two paths an explicit sequence with verification checkpoints.
If the Trusted Sources configuration guidance grows, move the environment-pair rules and dashboard steps into a references/ file and keep a one-line summary in SKILL.md to preserve the lean overview.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and imperative throughout ("replace raw curl with vercel curl", "Do not substitute x-vercel-oidc-token; that header carries an OIDC token into a Vercel Function"), teaching only Vercel-specific behavior Claude would not already know. No padded explanations, no concept tutorials, no filler. | 5 / 5 |
Actionability | Fully executable, copy-paste-ready commands cover the common cases: `vc curl` with full/path-only/custom-domain forms, `vc whoami` for identity checks, a complete `vc env run` agent-browser one-liner, `vc env pull .env.local --yes`, the exact header name, and a navigation pointer to Settings → Deployment Protection → Trusted Sources with the required environment pair. | 5 / 5 |
Workflow Clarity | Two access paths are clearly separated with explicit error-recovery branches ("If authentication fails, check the local identity...", "If the local CLI version does not provide the token..., refresh local development credentials") and a Diagnose-the-response section mapping symptoms to causes. It falls short of the 5 anchor because there is no end-to-end ordered sequence tying path selection, execution, and verification into a single explicit checklist-style flow. | 4 / 5 |
Progressive Disclosure | Sections are well organized (access paths, Trusted Sources rules, diagnosis, avoid list, related skills) and the ~93 lean lines are appropriately inlined for a single-purpose skill with no external reference files needed. Not the 5 anchor because the body exceeds the under-50-line threshold where section organization alone earns top marks, and the Trusted Sources configuration detail could live in a referenced file if the skill grows. | 4 / 5 |
