Vibecode Loom

You are building a lean indie version of Loom.

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 =====
# Loom indie build

## Goal

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

## Scope

Record screen and camera, encode video, upload to storage, generate transcript/summary, and serve a share page.

## 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:
- instant reliable hosting
- permissions
- comments
- analytics
- workspace libraries
- browser extensions

If those capabilities are essential, use OBS Studio 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 screen-record-and-share tool to replace Loom on macOS. Requirements:

- Two parts: a local recording CLI and a share server on my own VPS.
- Recording: `rec start` / `rec stop` wrapping ffmpeg's avfoundation capture,
  screen plus mic, saved to ~/Recordings/YYYY-MM-DD-HHMM.mp4. No camera bubble.
- On stop: transcode to web-friendly H.264, transcribe with whisper.cpp, then
  upload video and transcript to the server with rsync over SSH.
- The server (Node + Express + better-sqlite3 behind my existing reverse proxy)
  serves each recording at an unguessable /v/<random-id> URL: player, title, date,
  and the transcript below it, searchable in-page.
- `rec stop` ends by printing the share URL and copying it to my clipboard. Target:
  under a minute from stop to link for a 2-minute video.
- The index page listing all recordings stays private (localhost or VPN only); the
  share pages are link-only, no listing anywhere. No accounts, no telemetry.
- Out of scope: viewer analytics, comments, trimming, and team libraries. The
  unlisted URL is the entire permission model.
- README: macOS screen-recording and mic permissions, finding the right ffmpeg
  device index, and the server deploy steps.

## Required capabilities

- screen capture API
- ffmpeg
- object storage
- hosted app
- auth
- optional transcription API

## 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.

# Copy to .env and document every variable when it is introduced.
# Never put real credentials in this file.

You are building a production product version of Loom.

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 =====
# Loom product brief

## Problem

Local screen recording is easy, but instant hosting, permissions, viewer analytics, comments, trimming, and team libraries push it beyond one sitting.

## Product outcome

Record screen and camera, encode video, upload to storage, generate transcript/summary, and serve a share page.

## Target user

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

## Required capabilities

- screen capture API
- ffmpeg
- object storage
- hosted app
- auth
- optional transcription API

## Explicit non-goals for v1

- instant reliable hosting
- permissions
- comments
- analytics
- workspace libraries
- browser extensions

## 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 screen-record-and-share tool to replace Loom on macOS. Requirements:

- Two parts: a local recording CLI and a share server on my own VPS.
- Recording: `rec start` / `rec stop` wrapping ffmpeg's avfoundation capture,
  screen plus mic, saved to ~/Recordings/YYYY-MM-DD-HHMM.mp4. No camera bubble.

  unlisted URL is the entire permission model.
- README: macOS screen-recording and mic permissions, finding the right ffmpeg
  device index, and the server deploy steps.

## 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 Loom capabilities as implemented. The v1 non-goals in `PRODUCT.md` remain user-visible limitations until they are deliberately delivered.
