Password Reset
Let people back in without opening a hole for everyone else.
What it adds
A request-and-reset flow with expiring single-use tokens, identical public responses regardless of whether the account exists, and session cleanup afterwards.
What your agent is told to do
5
What your agent is told to do
5-
1
Return the same message and the same rough response time whether or not the address has an account. The reset form is the most common account-enumeration oracle in any app.
-
2
Store tokens hashed, expire them within an hour or so, and consume them on use.
-
3
After a successful reset, revoke all other sessions and notify the account by email that the password changed.
-
4
Rate-limit both the request step and the token-submission step, per address and per IP.
-
5
Do not sign the user in automatically from the reset link alone unless the app has decided that link possession equals authentication. Say which you chose and be consistent.
Edge cases it handles

Edge cases it handles
6- Requesting several resets must leave exactly one usable token — invalidate the earlier ones and say so in the email.
- A reset link opened after the password already changed must show a neutral expired state, not an error mentioning the account.
- Return-to URLs carried through the flow must be validated against an allowlist; an open redirect here hands over the session.
- Reset tokens must never appear in query strings that get logged, sent as referrers, or captured by analytics.
- If 2FA is enabled, resetting the password must not bypass it.
- The reset must reject the current password if the app forbids reuse, without confirming what the old one was.

Definition of done
8- Request responses are identical for existing and non-existing addresses.
- Tokens are hashed, expiring, and single-use, with older tokens invalidated on reissue.
- A successful reset revokes other sessions and emails the account.
- Return destinations are validated against an allowlist.
- Both request and submission steps are rate-limited.
- Reset does not bypass two-factor authentication.
- The feature matches the existing design system.
- No existing functionality is broken.

User Roles
User Roles
Not everyone should be able to do everything.
What it does
Role-based permissions, enforced on the server, with a UI that reflects them.
How it works
-
1
Define roles and their permissions in ONE place. Scattering
if user.admin?through the codebase is how authorization bugs happen. - 2 Enforce every permission server-side, at the controller or service layer.
- 3 Hide UI the user can't use — but never rely on hiding as the enforcement.

Member Directory
Member Directory
Show who is in the workspace and how to identify them.
What it does
A searchable, read-only roster of workspace members with their role, status, and the profile fields they have chosen to share.
How it works
- 1 Build this as a read view. Inviting members is owned by Team Invitations, changing roles is owned by User Roles, and seat counts are owned by Seat Management — link out to those rather than duplicating their controls here.
- 2 Show each member's display name, avatar, role, and status. Status is not decoration: pending, active, suspended, deactivated, and external guest must be visually distinct and filterable.
- 3 Respect per-field profile visibility. A field the member marked private is not rendered, not returned by the API, and not searchable — hiding it in the template while shipping it in the payload is not privacy.

Account Linking
Account Linking
Let one account sign in several ways without spawning duplicates.
What it does
Attach and detach sign-in methods — password, OAuth providers, SSO — on a single existing account.
How it works
- 1 Model sign-in methods as separate identity records attached to one account, rather than columns on the user.
- 2 Require a fresh re-authentication before any link or unlink. A stale session is enough to read the app; it is not enough to change how the account is entered.
- 3 Refuse to link an identity that is already attached to another account. Explain the conflict and point the user at recovery — do not silently steal the identity or silently create a second account.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
Need it tighter than that? Customize the feature and tell it exactly what you're running.
