75%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 a strong, highly actionable skill: executable copy-paste code for every auth flow, concrete MCP verification steps, an explicit ordering contract with the sibling provider-setup skill, and a completion checklist. Its main weaknesses are significant verbatim repetition of the same three warnings across four sections and a workflow spread across multiple sections rather than one consolidated sequence with feedback loops.
Suggestions
Consolidate each repeated warning (accessKey ≠ session / gateway 401, verifyOtp callback vs standalone, getSession vs deprecated getLoginState) into one canonical section and use one-line back-references elsewhere.
Move the Supabase compatibility comparison and the longest gotcha bullets into references/extended-guide.md to reduce body tokens.
Present one numbered end-to-end flow (verify provider → get/persist key → init → implement → Completion Bar) so the sequence and its validation checkpoints read as a single track.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Most content is high-value, non-obvious SDK knowledge (verifyOtp callback form, misleading getLoginState uid, gateway 401 semantics), but the same critical warnings are repeated nearly verbatim three to four times — the accessKey/session/401 warning appears in Common mistakes, the Parameter map, Quick Start comments, and the cookbook, and the verifyOtp-callback warning likewise recurs across sections. That is more than the 'minor instances' of anchor 4; consolidating each warning to one canonical location with brief back-references would tighten it without losing clarity. | 3 / 5 |
Actionability | The cookbook provides copy-paste-ready executable snippets for every flow (password sign-in, signUp + data.verifyOtp, OTP sign-in, forgot password, getSession guard, onAuthStateChange, signOut, auth gate) plus concrete MCP commands like queryAppAuth(action="listProviders") and manageAppAuth(action="patchLoginStrategy", patch={usernamePassword: true}), with a default UI contract and a Completion Bar checklist. Code covers the common cases completely and branches on error first. | 5 / 5 |
Workflow Clarity | Sequencing is explicit via the Activation Contract (auth-tool-cloudbase first, then this skill), ordered prerequisites (getPublishableKey → ensurePublishableKey → persist to .env.local), MCP provider verification before writing code, and a Completion Bar checklist that gates task completion. It falls short of anchor 5 because the full workflow is distributed across four sections rather than one sequence with explicit validate→fix→retry feedback loops, leaving minor checkpoint gaps. | 4 / 5 |
Progressive Disclosure | The bundle is well structured: a real one-level-deep reference (references/extended-guide.md, verified to exist) clearly signaled from the body and listed in a reference index, with the body staying at overview + cookbook altitude (~229 lines vs the 500-line limit). Minor gaps keep it from anchor 5: some long gotcha bullets and the Supabase comparison block could live in the reference, and the reference partially duplicates body cookbook content (login methods). | 4 / 5 |
