Vibecode Shotomatic

You are building a lean indie version of Shotomatic.

Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt.

===== README.md =====
# Shotomatic indie build

## Goal

Build the smallest trustworthy replacement for the core Shotomatic workflow for one developer or a tiny team.

## Scope

Pick a display or window, capture it on an interval, keep the session local, and export the ordered images.

## Quick start

1. Install the documented dependencies.
2. Copy `.env.example` to `.env`.
3. Run the development command chosen during implementation.
4. Complete the acceptance checks in `BUILD_PLAN.md`.

## Honest limits

This build deliberately does not replace:
- polished display, window, and custom-area selection
- reliable macOS permission setup and recovery
- Action Capture guide editing and annotations
- batch website capture with per-URL settings
- integrated PDF, ZIP, and MP4 export workflows

If those capabilities are essential, use Flameshot instead of pretending the gap is solved.

===== AGENTS.md =====
# Agent instructions

- Optimize for a working, understandable weekend build.
- Prefer the fewest moving parts that satisfy the brief.
- Do not invent cryptography, security guarantees, APIs, or compliance claims.
- Keep secrets out of source control and logs.
- Add focused tests for destructive, security-sensitive, and data-loss paths.
- Run the project checks before declaring the build complete.
- Record any deliberate shortcut in the README under "Tradeoffs".

===== BUILD_PLAN.md =====
# Build plan

## Original build brief

Build me a local macOS screenshot automation app covering Shotomatic's basic loop.
Requirements:

- Use SwiftUI and ScreenCaptureKit in a native macOS 14+ app with no third-party packages.
- Provide a source picker for one display or one visible window, with thumbnail previews.
- Let me set an interval in seconds and stop after a screenshot count or elapsed duration.
- Show a three-second countdown, live running status, captured count, and a clear Stop button.
- Save every capture as PNG or JPEG in ~/Pictures/Capture Sessions/<timestamp>/.
- Keep a local session list with thumbnails; open a session in Finder or delete it with confirmation.
- Add one optional keypress after each capture using CGEvent so paged content can advance.
- Check Screen Recording and Accessibility permission before starting; explain how to grant each.
- Never upload files, add accounts, or collect telemetry. The app must work fully offline.
- Handle a display or window disappearing mid-session without losing images already captured.
- Include a small unit-tested state machine for idle, countdown, running, stopping, and failed states.
- Include a README with build, permission, and signing notes plus a manual smoke-test checklist.
- Out of scope: custom-area capture, website batches, guide editing, annotations, PDF/ZIP/MP4 export.
- Produce an Xcode project that builds and runs, then run the unit tests before finishing.

## Required capabilities

- macOS 14 or later
- Xcode command line tools
- Screen Recording permission
- Accessibility permission for optional keypress automation

## Delivery order

1. Scaffold the smallest runnable application and document its commands.
2. Implement the primary data model and core workflow.
3. Add validation, safe failure states, and persistence.
4. Cover the critical path with automated tests.
5. Exercise a clean install from the README and fix every missing step.

## Done when

- A new user can go from clone to first successful workflow using only the README.
- The core workflow works without paid infrastructure unless the brief requires it.
- Tests cover the highest-risk behavior.
- Known limitations are explicit rather than hidden.

You are building a production product version of Shotomatic.

Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt.

===== PRODUCT.md =====
# Shotomatic product brief

## Problem

A personal timed screenshot loop is a realistic weekend build. Matching reliable capture across Mac apps, permission recovery, website batches, guide editing, and polished exports is a much larger product.

## Product outcome

Pick a display or window, capture it on an interval, keep the session local, and export the ordered images.

## Target user

A serious builder who needs a maintainable product foundation rather than a one-off demo.

## Required capabilities

- macOS 14 or later
- Xcode command line tools
- Screen Recording permission
- Accessibility permission for optional keypress automation

## Explicit non-goals for v1

- polished display, window, and custom-area selection
- reliable macOS permission setup and recovery
- Action Capture guide editing and annotations
- batch website capture with per-URL settings
- integrated PDF, ZIP, and MP4 export workflows

## Success criteria

- The primary workflow is measurable end to end.
- Setup is reproducible in a clean environment.
- Failure, recovery, and support paths are documented.
- Product claims match what the implementation actually guarantees.

===== ARCHITECTURE.md =====
# Architecture

## Starting brief

Build me a local macOS screenshot automation app covering Shotomatic's basic loop.
Requirements:

- Use SwiftUI and ScreenCaptureKit in a native macOS 14+ app with no third-party packages.
- Provide a source picker for one display or one visible window, with thumbnail previews.
- Let me set an interval in seconds and stop after a screenshot count or elapsed duration.
- Show a three-second countdown, live running status, captured count, and a clear Stop button.
- Save every capture as PNG or JPEG in ~/Pictures/Capture Sessions/<timestamp>/.

- Check Screen Recording and Accessibility permission before starting; explain how to grant each.
- Never upload files, add accounts, or collect telemetry. The app must work fully offline.
- Handle a display or window disappearing mid-session without losing images already captured.
- Include a small unit-tested state machine for idle, countdown, running, stopping, and failed states.
- Include a README with build, permission, and signing notes plus a manual smoke-test checklist.
- Out of scope: custom-area capture, website batches, guide editing, annotations, PDF/ZIP/MP4 export.
- Produce an Xcode project that builds and runs, then run the unit tests before finishing.

## Boundaries

Separate the product into replaceable modules for interface, application logic, persistence, external integrations, and operational concerns. Keep domain logic independent from delivery frameworks and vendors.

## Production baseline

- Configuration: validated at startup with safe local defaults where possible.
- Security: least privilege, input validation, secret redaction, rate limits on abuse-prone paths, and no invented security primitives.
- Data: explicit schema and migrations, transactional writes where integrity matters, backup and restore instructions.
- Integrations: adapters around third-party providers, idempotent webhook or job processing, bounded retries, and timeouts.
- Observability: structured logs with request or operation IDs, an error-tracking hook, and health/readiness checks where a server exists.
- Quality: unit tests for domain rules, integration tests at module boundaries, and one end-to-end critical-path test.

## Decision records

For each major dependency, document why it was chosen, its failure mode, and how it can be replaced. Do not introduce infrastructure until a requirement justifies it.

===== AGENTS.md =====
# Agent instructions

- Read `PRODUCT.md` and `ARCHITECTURE.md` before changing code.
- Implement milestone by milestone; keep each change reviewable and leave the application runnable.
- Treat authentication, payments, encryption, imports, webhooks, and destructive actions as high-risk boundaries when present.
- Never invent cryptography or silently weaken a requirement to make a test pass.
- Use provider interfaces for external services and deterministic fakes in tests.
- Add migrations and rollback or recovery notes for persistent data changes.
- Log useful operational context without credentials, tokens, passwords, or personal data.
- Update documentation and run all checks before completing a milestone.

===== MILESTONES.md =====
# Delivery milestones

## M0 — Decisions and scaffold

- Confirm the runtime, persistence model, threat boundaries, and deployment target.
- Create a reproducible local environment and continuous checks.

## M1 — Core workflow

- Implement the smallest end-to-end product path with validation and tests.
- Keep integrations behind interfaces.

## M2 — Trust layer

- Add secure failure behavior, recovery paths, audit-relevant events, and data safeguards.
- Test abuse cases and destructive operations.

## M3 — Operability

- Add structured logs, error reporting hooks, health signals, backup/restore documentation, and deployment configuration.

## M4 — Release gate

- Run a clean-install test, critical-path end-to-end test, dependency review, and documented rollback exercise.
- Compare the shipped behavior with `PRODUCT.md` and publish remaining limitations.

===== OPERATIONS.md =====
# Operations

## Before release

- Validate configuration and secrets at startup.
- Define backup, restore, and rollback procedures and test them.
- Document logs, error tracking, health signals, and alert ownership.
- Set dependency update and vulnerability review expectations.

## Incident checklist

1. Contain the issue without destroying evidence or user data.
2. Record the timeline and affected scope.
3. Rotate exposed secrets and revoke compromised sessions or credentials.
4. Restore from a verified source when needed.
5. Document the root cause, remediation, and regression test.

## Launch constraint

Do not market omitted Shotomatic capabilities as implemented. The v1 non-goals in `PRODUCT.md` remain user-visible limitations until they are deliberately delivered.
