Review Scalekit Code

Review Scalekit code

Review a Scalekit snippet. Then stop. Do not write a new login.

Guardrails

• MUST review only. MUST NOT write a new login, callback, session, or logout.
• MUST open references/REFERENCE.md and references/COMMON-MISTAKES.md. Do not paste them here.
• MUST say "This method could not be verified" when a call is not in the reference or a live source.
• MUST NOT treat SCALEKIT_ENV_URL as valid. The env name is SCALEKIT_ENVIRONMENT_URL. Do not prepend https://.

Gotchas

• If the user has no snippet and wants new auth, name the implementing skill and stop.
• SaaSKit login → implement-saaskit (Node), implement-saaskit-nextjs, or implement-saaskit-python.
• AgentKit → integrate-agentkit. SCIM → implement-scim. SSO → implement-sso. Sessions after login → manage-saaskit-sessions.
• A one-line corrected call is review. A new auth flow is generation. Do not generate.
• Cookies: httpOnly, secure in production, sameSite: 'lax'. Never strict.
• next / returnTo is a relative path only.
• Client is a module-level singleton.

Step 1 — Confirm this is a review

Need an existing snippet.

• No snippet, or the user asked to generate login / callback / logout → name implement-saaskit (or the sibling for Next.js, Python, AgentKit). Stop.
• Snippet exists → stay.

Done when: a snippet is in hand, or the implementing skill is named and this skill has stopped.

Step 2 — Identify language and product

Product: SaaSKit (login, sessions, SSO, SCIM, RBAC) or AgentKit (connections, tools, MCP auth).

Done when: language, package, and product are named.

Step 3 — SDK correctness

Open references/REFERENCE.md. Then stop reading it.

For every Scalekit call, record pass or fail:

1. Import path matches the table
2. Method name exists for that SDK
3. Parameters match name, order, and type
4. Return shape is handled (Promise, dict, (result, error), checked exception)
5. Client is constructed from SCALEKIT_ENVIRONMENT_URL, SCALEKIT_CLIENT_ID, SCALEKIT_CLIENT_SECRET

If the snippet is raw HTTP, check the REST section of that same file: path, method, and Bearer token from POST /oauth/token.

Open references/COMMON-MISTAKES.md for the wrong → right pairs. Then stop reading it.

Done when: every Scalekit call is pass, fail, or "could not be verified".

Step 4 — Flow and security

Record pass, fail, or waive (not in this snippet) for:

1. Login has a callback
2. Callback compares stored state to the query state before authenticateWithCode
3. Logout calls getLogoutUrl with idTokenHint
4. Refresh exists if offline_access is used
5. Cookies are httpOnly, secure in production, sameSite: 'lax'
6. state is cryptographically random
7. next is a relative path
8. Secrets come from env vars
9. Webhooks verify the signature on the raw body
10. OAuth redirect uses window.location.href, not router.push

Do not write the missing route. Name the implementing skill.

Done when: every item is pass, fail, or waive.

Step 5 — Environment

Record pass or fail for:

1. Env name is SCALEKIT_ENVIRONMENT_URL, never SCALEKIT_ENV_URL
2. No https:// prepended onto a value that already has a scheme
3. Redirect URI matches the dashboard
4. Domain is https://<subdomain>.scalekit.com, .scalekit.dev, or https://app.<domain> (self-hosted)

Done when: all 4 rows have pass or fail.

Step 6 — Unknown methods

If a call is not in references/REFERENCE.md:

1. Live SDK REFERENCE.md at https://raw.githubusercontent.com/scalekit-inc/scalekit-sdk-{node,python,go,java}/main/REFERENCE.md
2. REST API at https://docs.scalekit.com/apis
3. State: "This method could not be verified."

Do not invent a method.

Done when: every unknown call is verified or marked unverified.

Step 7 — Report and stop

For each fail: What's wrong → Why it matters → the correct call from the reference, or the implementing skill name.

If every check passed: say the snippet is right.

Do not write a new login.

Done when: the user has the report, and this skill has not written a new auth flow.

Reach for

• references/REFERENCE.md for signatures
• references/COMMON-MISTAKES.md for wrong → right pairs
• implement-saaskit to write login
• implement-saaskit-nextjs for Next.js App Router
• implement-saaskit-python for Django, FastAPI, or Flask
• integrate-agentkit for a connected account
• implement-scim / implement-sso / manage-saaskit-sessions when that is the gap
