The body is a dense, actionable, well-sequenced Better Auth reference with concrete commands, config keys, and an explicit setup verification step. Its main weakness is structural: it is a monolithic single-file reference with no bundled reference files, so substantial reference material sits inline rather than behind one-level-deep links.
Suggestions
Move detailed reference material (Core Config Options table, Session Management, Hooks, and the Plugins catalog) into bundled files under references/ (e.g. references/options.md, references/plugins.md) and keep SKILL.md as a lean overview with clearly signaled links, raising progressive_disclosure toward the score-3 split-files pattern.
Add a complete, copy-paste-ready auth.ts example showing betterAuth({ database, baseURL/secret, emailAndPassword, plugins }) so the central artifact is fully assembled, not just described as 'Create auth.ts with database + config'.
Turn the setup verification step into an explicit feedback loop, e.g. 'If GET /api/auth/ok does not return { status: "ok" }, check BETTER_AUTH_SECRET/BETTER_AUTH_URL and re-run bun x @better-auth/cli@latest migrate', to make the validation checkpoint a true error-recovery loop.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Dense, bullet/table-driven reference with no conceptual padding (it never explains what auth or a database is); every section adds Better-Auth-specific knowledge Claude would not reliably know, fitting the lean score-3 anchor. | 3 / 3 |
Actionability | Concrete commands (bun add, migrate), specific config keys with values ({ enabled: true }, basePath defaults), an executable plugin import snippet, type expressions, and a verify endpoint (GET /api/auth/ok → { status: "ok" }) — concrete and executable rather than abstract. | 3 / 3 |
Workflow Clarity | Setup Workflow is a numbered 1-6 sequence with an explicit validation checkpoint (step 6 verify), and the Common Gotchas section supplies recovery context, matching the explicit-validation score-3 anchor. | 3 / 3 |
Progressive Disclosure | Well-organized with clear section headers, but ~190 lines of inline reference (full options table, session/cookie reference, hooks, plugin catalog) that could live in separate files; there are no bundled reference files and the under-50-line exception does not apply, so it fits the score-2 "content that should be separate is inline" anchor rather than the split-files score-3 anchor. | 2 / 3 |
