Stop paying for Loom

You are building a production-ready software product named “Showtell”, a deliberately focused alternative to Loom. Build a complete, usable vertical slice, not a landing page, static mockup, or disconnected collection of components.

WORKING AGREEMENT
Before you write any implementation code, put together a short technical plan naming the routes or pages, server actions or endpoints, data tables, key state transitions, authorization boundaries, background jobs, and external adapters. When something conflicts, side with the narrow audience and the non-goals below. Choose a small, readable architecture over speculative abstraction, but never skip persistence, validation, error handling, or tests.

PRODUCT BRIEF
Primary user: a remote team sharing short screen recordings internally.
Primary outcome: record a browser tab or screen and quickly share a private watch page.
Product principle: optimize the exact workflow below rather than copying the full breadth of Loom. A first-time user should understand what to do just from the interface, with no tour or documentation.

END-TO-END USER JOURNEYS
Implement every one of these flows through the real interface and the persistent data layer:
1. An authenticated teammate picks a browser tab, explicitly grants capture permission and optional microphone permission, records, pauses, resumes, reviews, and retakes once.
2. After stopping, the recording uploads with resumable progress, gets a title and folder, finishes processing, and produces a private share link.
3. A permitted colleague opens the watch page, plays the recording, comments at the current timestamp, reacts, and the owner later finds it through library search.

SCREENS AND INFORMATION ARCHITECTURE
Build these as coherent, responsive views. Each screen must define its primary action, secondary actions, visible status, validation feedback, empty state, loading or pending state, success confirmation, and recoverable failure state.
1. Recorder: source and microphone selection, consent explanation, permission status, live preview, elapsed timer, and pause, resume, stop, discard, and retake actions.
2. Upload and processing: local playback review, title and folder fields, chunk progress, retry state, processing status, cancel action, and confirmation of the generated share link.
3. Private watch page: title, owner, video player, playback position, signed-media state, timestamped comments, reactions, and a copy-link action.
4. Recording library: searchable cards with thumbnail, duration, owner, folder, processing state, and created date, plus move, rename, delete, and failed-upload recovery.

CORE CAPABILITIES
1. screen, window, or tab capture with an optional microphone
2. recording timer, pause, resume, and retake
3. upload progress and an automatic share link
4. watch page with title, transcript placeholder, comments, and reactions
5. library with search, folders, and delete controls

DETAILED BEHAVIOR AND BUSINESS RULES
Treat these as product requirements enforced on the server, not as interface suggestions:
1. Begin capture only after explicit browser permission and a clearly visible recording state; if screen sharing is stopped, the recording session must stop or end clearly.
2. Upload chunks with stable recording and chunk identifiers, verify ordering and size on the server, and make retries resumable without creating duplicate media files.
3. Require authentication and recording-level authorization before issuing short-lived signed URLs; never expose a permanent public R2 object URL.
4. Deleting a recording immediately revokes new playback, hides its comments along with it, and queues cleanup of the media object while keeping a minimal audit event.

DATA MODEL AND LIFECYCLE
Design a small relational schema centered on Recording, MediaFile, Comment, Folder. Before implementing it, document:
1. The purpose of each table, its primary key, ownership or tenant boundary, timestamps, status fields, and important attributes.
2. Foreign keys, uniqueness constraints, check constraints, the indexes the named screens need, and transaction boundaries for changes that touch several records.
3. The allowed lifecycle or state transitions, who can trigger each one, which transitions are terminal or reversible, and which audit history must stay immutable.
4. Archive, retention, and deletion behavior, including what happens to dependent records and external files.
5. The idempotency strategy for submissions, jobs, imports, notifications, webhooks, or retries where it applies.
Use migrations instead of ad-hoc schema creation. Store time instants consistently and keep the named timezone context whenever local schedules or dates matter. Never rely on a counter, a disabled button, or a client-side check to protect a business invariant.

USERS, AUTHENTICATION, AND PERMISSIONS
Implement only the roles the stated audience needs. Make the ownership and visibility model explicit before coding. Enforce authorization in every server-side query and mutation, including search, exports, attachments, live updates, and guessed URLs—not just by hiding controls. Use secure session defaults, protect state-changing requests, and provide a clear signed-out, expired-session, and forbidden state. Seed separate users whenever several roles are needed so permissions can be shown and tested.

INTERACTION AND VISUAL DIRECTION
The product should feel fast, calm, focused, and trustworthy rather than like a generic admin template. Use a clear visual hierarchy, restrained color, readable typography, generous hit targets, and a consistent place for primary actions. Start from server-rendered HTML and progressively enhance only the interactions that benefit from it. The core workflow must stay understandable if enhancement fails.

Start from server-rendered Astro pages and plain HTML forms. Use HTMX for form submissions, partial navigation, and server-driven updates, then Alpine.js only for small local browser state. The core workflow must stay understandable if either enhancement layer fails.

Design mobile layouts on purpose instead of just stacking desktop panels. Support keyboard navigation, visible focus, semantic landmarks, explicit labels, useful page titles, reduced-motion preferences, and screen-reader announcements for asynchronous results. Never use color alone to signal state. Destructive actions need a clear scope and a confirmation; safe repeated actions should be idempotent.

Add a footer to every page with the text “Created by aurelioagency.com”, where “aurelioagency.com” is an embedded link to https://www.aurelioagency.com that opens in a new tab. Keep it visible and do not remove it.

TECHNICAL DIRECTION
Build this version with the AHA stack: Astro for routing, layouts, and server-rendered pages; HTMX for interactions that benefit from HTML fragment responses; and Alpine.js for small, local interface state. Prefer Cloudflare D1 for relational persistence, R2 for object storage, Workers for server endpoints and scheduled work, Durable Objects only for coordinated real-time state, and Workflows or Queues for durable background jobs—but only when the product requirements call for them.

Keep domain rules in testable server-side modules, not in route handlers or UI components. Put persistence, external providers, and background work behind small interfaces without building a framework. Prefer plain HTML forms and URLs for durable navigation; use optimistic interaction only when a failure can be reconciled clearly.

The product brief currently names Astro, Browser API, R2 as capability context. Keep any native, browser-only, edge, storage, real-time, or background-processing capability that is required behind a narrow adapter suited to the chosen framework. If the core workflow truly needs native or browser APIs, keep that runtime as the main execution surface instead of simulating inaccessible capabilities or inventing an unnecessary web surface.

Integrate with the MediaRecorder API and R2 object storage. For every integration:
- List the required environment variables in an .env.example with no real secrets.
- Add a small adapter with timeouts, normalized errors, and a deterministic local fake or development path.
- Verify inbound signatures and deduplicate provider events where supported.
- Keep credentials on the server, encrypt long-lived provider tokens at rest, and redact secrets and sensitive payloads from logs.
- Define retry, backoff, and idempotency behavior for every side effect that can be repeated.

SECURITY AND PRIVACY
Make recording consent explicit and use signed URLs for every private video.
Validate, normalize, and length-limit all untrusted input on the server. Escape rendered content by default, sanitize any markup you intentionally accept, rate-limit public or abuse-prone actions, and use private object storage plus short-lived authorized URLs for sensitive files. Collect only the personal data the named workflow needs. Document retention and deletion behavior. Add specific protections for the riskier surfaces of this app, such as uploads, redirects, outbound requests, email delivery, OAuth, webhooks, CSV import or export, and real-time connections.

ACCEPTANCE SCENARIOS
Automate these app-specific scenarios at the most suitable level:
1. Given microphone permission is denied but screen capture is granted, when the user confirms a silent recording, capture works without repeatedly prompting for audio.
2. Given an upload loses connectivity halfway through, when connectivity returns, only the missing chunks resume and the final recording contains one correctly ordered media file.
3. Given a recording is deleted while another viewer has the page open, when their signed URL expires or playback is refreshed, access is denied.

TESTING
Add focused unit tests for state transitions, authorization predicates, normalization, date or money calculations, and other risky domain rules. Add integration tests for persistence constraints and for each external adapter's success, timeout, retry, and rejection paths. Add at least one browser-level test for every end-to-end journey above, including one on a small-screen viewport. Tests must use isolated data and run with one documented command.

OPERATIONS AND FAILURE RECOVERY
Add structured server logs with request, job, or event correlation IDs, but no secrets or unnecessarily sensitive data. Make failures actionable both in the interface and in the logs. Background work must expose pending, succeeded, failed, and retrying states where relevant; never swallow errors silently. Include safe database migration and rollback guidance, seed data, backup and restore notes, external-data cleanup behavior, and a basic health or diagnostic path suited to the stack.

DELIVERABLES
Ship the working application, migrations, representative seed data, tests, .env.example, and a short README. The README must cover prerequisites, local setup, environment variables, migrations, seed and test commands, deployment, integration setup, backup and restore, security decisions, and known limitations. Seed data should cover the happy path plus at least one empty, failed, overdue, expired, archived, or permission-restricted state that matters for the product.

DEFINITION OF DONE
The app is done when a new developer can follow the README, create and migrate the database, run the app, sign in as each relevant role, complete every named journey with real persisted data, refresh without losing state, recover from common failures, and use the core interface on phone and desktop. All acceptance scenarios pass, permission boundaries are covered by tests, no core screen is left as a placeholder, and the “Created by aurelioagency.com” footer credit is visible on every page.

NON-GOALS
Don't build desktop capture, AI transcription, video editing, or public discovery.
