Opinion Stage

WORKING SLICE
Create a poll or quiz with a reviewed result calculation, publish an embed and show aggregate responses. Keep identifiable answers private and allow an anonymous mode with clearly stated limitations.

Build this scoped Opinion Stage-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.
- A versioned JSON form schema shared by a controlled builder, public renderer and server-side validator.

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: templates, hosted delivery, lead features, and engagement reporting; advanced branching

Data model and correctness
poll/quiz schemas, choices, scoring rules, respondent tokens, answer versions and aggregate windows
Invariant: Quiz scores are recomputed server-side; editing choices creates a new version rather than changing the meaning of historical answers.
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. Apply per-form submission limits and spam controls; keep responses private and separate public form IDs from management permissions.

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: Create a poll or quiz with a reviewed result calculation, publish an embed and show aggregate responses. Keep identifiable answers private and allow an anonymous mode with clearly stated limitations. Record prerequisites, select representative user-owned fixtures and document the unsupported features: templates, hosted delivery, lead features, and engagement reporting; advanced branching
2. Phase 2 — Durable model. Model poll/quiz schemas, choices, scoring rules, respondent tokens, answer versions and aggregate windows Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Quiz scores are recomputed server-side; editing choices creates a new version rather than changing the meaning of historical answers.
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. Apply per-form submission limits and spam controls; keep responses private and separate public form IDs from management permissions. 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. Tamper with a browser-supplied score and get the server result; a renamed choice preserves the original label in an earlier response export. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Tamper with a browser-supplied score and get the server result; a renamed choice preserves the original label in an earlier response export.
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 Opinion Stage

## Project scope
Create a poll or quiz with a reviewed result calculation, publish an embed and show aggregate responses. Keep identifiable answers private and allow an anonymous mode with clearly stated limitations.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Opinion Stage, create a poll, quiz, or survey and embed it with basic response analytics. The hard boundary is templates, hosted delivery, lead features, and engagement reporting, plus integrations, deliverability, and workflow depth.
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. A versioned JSON form schema shared by a controlled builder, public renderer and server-side validator.
- Scope boundary: templates, hosted delivery, lead features, and engagement reporting; advanced branching

## 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.
- A versioned JSON form schema shared by a controlled builder, public renderer and server-side validator.
- Domain model: poll/quiz schemas, choices, scoring rules, respondent tokens, answer versions and aggregate windows

## 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. Apply per-form submission limits and spam controls; keep responses private and separate public form IDs from management permissions.
- Correctness boundary: Quiz scores are recomputed server-side; editing choices creates a new version rather than changing the meaning of historical answers.
- 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.

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 Opinion Stage-inspired workflow with owned or clearly labeled sample data: Create a poll or quiz with a reviewed result calculation, publish an embed and show aggregate responses. Keep identifiable answers private and allow an anonymous mode with clearly stated limitations.
- Publish a reproducible walkthrough with this observable result: Tamper with a browser-supplied score and get the server result; a renamed choice preserves the original label in an earlier response export.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: templates, hosted delivery, lead features, and engagement reporting; advanced branching Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Create a poll or quiz with a reviewed result calculation, publish an embed and show aggregate responses. Keep identifiable answers private and allow an anonymous mode with clearly stated limitations. Record prerequisites, select representative user-owned fixtures and document the unsupported features: templates, hosted delivery, lead features, and engagement reporting; advanced branching
2. Phase 2 — Durable model. Model poll/quiz schemas, choices, scoring rules, respondent tokens, answer versions and aggregate windows Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Quiz scores are recomputed server-side; editing choices creates a new version rather than changing the meaning of historical answers.
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. Apply per-form submission limits and spam controls; keep responses private and separate public form IDs from management permissions. 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. Tamper with a browser-supplied score and get the server result; a renamed choice preserves the original label in an earlier response export. 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.
