SurveySparrow

WORKING SLICE
Create a conversational survey with accessible step navigation, save partial progress under a scoped respondent token and export completed responses. Add a scheduled reminder only for explicitly opted-in invitations.

Build this scoped SurveySparrow-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: enterprise workflow logic; spam and abuse defense at scale

Data model and correctness
survey versions, conversational questions, invitations, response progress and aggregate reports
Invariant: Partial answers and final submissions are distinct; editing a survey cannot reinterpret an existing response's branch path.
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 conversational survey with accessible step navigation, save partial progress under a scoped respondent token and export completed responses. Add a scheduled reminder only for explicitly opted-in invitations. Record prerequisites, select representative user-owned fixtures and document the unsupported features: enterprise workflow logic; spam and abuse defense at scale
2. Phase 2 — Durable model. Model survey versions, conversational questions, invitations, response progress and aggregate reports Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Partial answers and final submissions are distinct; editing a survey cannot reinterpret an existing response's branch path.
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. Resume a partially answered survey with its original version; a revoked invitation cannot expose previous answers and reminder retries do not send twice. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Resume a partially answered survey with its original version; a revoked invitation cannot expose previous answers and reminder retries do not send twice.
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 SurveySparrow

## Project scope
Create a conversational survey with accessible step navigation, save partial progress under a scoped respondent token and export completed responses. Add a scheduled reminder only for explicitly opted-in invitations.

Catalogue verdict: kinda. The visible experience surveys loop is buildable, but a credible replacement needs more than the first screen. SurveySparrow earns its keep through delivery, integrations, compliance, so expect a weekend or multi-day build and a narrower personal scope.
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: enterprise workflow logic; spam and abuse defense at scale

## 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: Partial answers and final submissions are distinct; editing a survey cannot reinterpret an existing response's branch path.
- 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 SurveySparrow-inspired workflow with owned or clearly labeled sample data: Create a conversational survey with accessible step navigation, save partial progress under a scoped respondent token and export completed responses. Add a scheduled reminder only for explicitly opted-in invitations.
- Publish a reproducible walkthrough with this observable result: Resume a partially answered survey with its original version; a revoked invitation cannot expose previous answers and reminder retries do not send twice.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: enterprise workflow logic; spam and abuse defense at scale Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Create a conversational survey with accessible step navigation, save partial progress under a scoped respondent token and export completed responses. Add a scheduled reminder only for explicitly opted-in invitations. Record prerequisites, select representative user-owned fixtures and document the unsupported features: enterprise workflow logic; spam and abuse defense at scale
2. Phase 2 — Durable model. Model survey versions, conversational questions, invitations, response progress and aggregate reports Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Partial answers and final submissions are distinct; editing a survey cannot reinterpret an existing response's branch path.
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. Resume a partially answered survey with its original version; a revoked invitation cannot expose previous answers and reminder retries do not send twice. 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.
