WishKit

WORKING SLICE
Expose a small feature-board API and embeddable widget for the owner's app. Let signed-in users submit/vote/comment and let an authorized moderator change statuses or remove abuse.

Build this scoped WishKit-inspired workflow with a documented data model and visible failure states.

Architecture
- Next.js App Router and TypeScript for server-rendered pages and validated mutations.
- PostgreSQL with Drizzle migrations; Better Auth sessions for a small private workspace.

Prerequisites and limits
A supported Node release, PostgreSQL, HTTPS for a shared deployment, and a backup destination. Begin with one workspace and explicit owner/member permissions.
Outside this release: A maintained SDK per platform, so every new client is your code to write and version; Anti-abuse that someone else already tuned: duplicate votes, spam floods, garbage submissions

Data model and correctness
products, feature requests, authenticated votes, comments, moderation states and embed configurations
Invariant: An embed identifier is public and cannot authenticate a voter; server-side membership and a unique vote constraint prevent duplicate counting.
Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.

Security and privacy
Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML.

Recovery and export
Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Expose a small feature-board API and embeddable widget for the owner's app. Let signed-in users submit/vote/comment and let an authorized moderator change statuses or remove abuse. Record prerequisites, select representative user-owned fixtures and document the unsupported features: A maintained SDK per platform, so every new client is your code to write and version; Anti-abuse that someone else already tuned: duplicate votes, spam floods, garbage submissions
2. Phase 2 — Durable model. Model products, feature requests, authenticated votes, comments, moderation states and embed configurations Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: An embed identifier is public and cannot authenticate a voter; server-side membership and a unique vote constraint prevent duplicate counting.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.
4. Phase 4 — Permissions and integration failure. Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Replay one vote request and count it once; an untrusted origin cannot invoke moderator actions and a deleted comment stays out of public responses. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Replay one vote request and count it once; an untrusted origin cannot invoke moderator actions and a deleted comment stays out of public responses.
Use real source data or clearly labeled fixtures. Explain unsupported input and provider failures; do not fabricate analytics, delivery receipts, accuracy claims or security guarantees.

# AGENTS.md — Build guide for WishKit

## Project scope
Expose a small feature-board API and embeddable widget for the owner's app. Let signed-in users submit/vote/comment and let an authorized moderator change statuses or remove abuse.

Catalogue verdict: kinda. The data model here is four tables and a sort function: wishes, votes, comments, statuses. An agent can produce the whole web board plus a REST API in a single sitting, and it will work fine for a side project. The part that is actually work is everything after that: a native in-app widget for each platform you ship on, anonymous device identity so the same user cannot vote fifty times, spam and profanity handling, and an endpoint that stays up for people who already installed your binary. Nothing there is hard, it is just a real backend you now own forever. Build it if you like owning it, pay if your roadmap board is not the thing you want to be on call for.
Use the implementation prompt below to define the deliverable. Complete each phase's acceptance checks before extending the scope.

## Working agreement
- Inspect the repository and its existing instructions before choosing paths, dependencies or commands. Keep one coherent stack and explain changes to the proposed architecture.
- Plan a vertical slice that accepts a real input and produces the useful output described below. Persist only the state the prompt calls for; respect memory-only and upstream-managed workflows. Use fixtures only when they are clearly labelled.
- After scaffolding, document the actual install, development, check and build commands in README and keep them synchronized with the package or project manifest. Do not report commands as successful unless they ran.
- Work in small steps. At handoff, list implemented flows, checks actually performed, remaining blockers, and any credentials or provider setup the owner must supply.
- Do not publish, spend money, contact customers, delete source data or run irreversible migrations without the project owner's authorization.

## Prerequisites
- A supported Node release, PostgreSQL, HTTPS for a shared deployment, and a backup destination. Begin with one workspace and explicit owner/member permissions.
- Implementation components: Next.js App Router and TypeScript for server-rendered pages and validated mutations. PostgreSQL with Drizzle migrations; Better Auth sessions for a small private workspace.
- Scope boundary: A maintained SDK per platform, so every new client is your code to write and version; Anti-abuse that someone else already tuned: duplicate votes, spam floods, garbage submissions

## Stack and architecture
- Next.js App Router and TypeScript for server-rendered pages and validated mutations.
- PostgreSQL with Drizzle migrations; Better Auth sessions for a small private workspace.
- Domain model: products, feature requests, authenticated votes, comments, moderation states and embed configurations

## Security and data integrity
- Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML.
- Correctness boundary: An embed identifier is public and cannot authenticate a voter; server-side membership and a unique vote constraint prevent duplicate counting.
- Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.
- Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching.

## Agent implementation rules
- Project rule — data model: products, feature requests, authenticated votes, comments, moderation states and embed configurations

Read the linked SKILL.md and its dependencies before adding a skill. Select only the skills matching this project's runtime and task; their documentation does not supply API access, credentials or approval to perform external actions. Pin the reviewed revision where the tool supports it. Follow the chosen agent's documented project-level installation mechanism.

## Distribution ideas
These are optional planning notes. Obtain the owner's approval before publishing or contacting anyone.
- Demonstrate the actual WishKit-inspired workflow with owned or clearly labeled sample data: Expose a small feature-board API and embeddable widget for the owner's app. Let signed-in users submit/vote/comment and let an authorized moderator change statuses or remove abuse.
- Publish a reproducible walkthrough with this observable result: Replay one vote request and count it once; an untrusted origin cannot invoke moderator actions and a deleted comment stays out of public responses.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: A maintained SDK per platform, so every new client is your code to write and version; Anti-abuse that someone else already tuned: duplicate votes, spam floods, garbage submissions Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Expose a small feature-board API and embeddable widget for the owner's app. Let signed-in users submit/vote/comment and let an authorized moderator change statuses or remove abuse. Record prerequisites, select representative user-owned fixtures and document the unsupported features: A maintained SDK per platform, so every new client is your code to write and version; Anti-abuse that someone else already tuned: duplicate votes, spam floods, garbage submissions
2. Phase 2 — Durable model. Model products, feature requests, authenticated votes, comments, moderation states and embed configurations Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: An embed identifier is public and cannot authenticate a voter; server-side membership and a unique vote constraint prevent duplicate counting.
3. Phase 3 — Complete the first useful path. Implement the workflow's input, review and output interface, with clear controls and explicit empty/error states. Commit related database changes in one transaction. Use version checks for competing edits and an outbox for external notifications; retry delivery independently of saving the record.
4. Phase 4 — Permissions and integration failure. Authorize every record read and mutation on the server using its workspace membership; validate payloads, protect mutations against CSRF, and escape user-authored HTML. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export versioned JSON plus attachments and a readable CSV summary. Restore into a separate database and compare record IDs and attachment checksums before switching. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Replay one vote request and count it once; an untrusted origin cannot invoke moderator actions and a deleted comment stays out of public responses. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

## Completion evidence
Demonstrate the prompt's acceptance scenarios against the scoped workflow. Include setup from a clean checkout and failure recovery. Check persistence across restart and export/restore only for the state the prompt says to store; for memory-only tools, confirm that temporary content is discarded as specified. Record actual results and remaining limitations. A detailed plan alone does not establish a working replacement.
