Supernotes

WORKING SLICE
Capture compact note cards, connect them with explicit links and browse a focused collection view. Search quickly and export each card with its links and original creation metadata.

Build this scoped Supernotes-inspired workflow with a documented data model and visible failure states.

Architecture
- Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge.
- SQLite for structured state and search; user-owned files for original documents and attachments.

Prerequisites and limits
Node and the Rust toolchain, a supported desktop build environment and an explicitly selected data folder. Remote sync is outside the initial scope.
Outside this release: real-time collaboration, mobile polish, sync, and card-based workflow refinement; frictionless mobile capture

Data model and correctness
note cards, stable card IDs, tags, parent/related links, collections and Markdown revisions
Invariant: Cards retain identity when retitled or moved; a collection membership change cannot delete the underlying note.
Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.

Security and privacy
Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview.

Recovery and export
Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Capture compact note cards, connect them with explicit links and browse a focused collection view. Search quickly and export each card with its links and original creation metadata. Record prerequisites, select representative user-owned fixtures and document the unsupported features: real-time collaboration, mobile polish, sync, and card-based workflow refinement; frictionless mobile capture
2. Phase 2 — Durable model. Model note cards, stable card IDs, tags, parent/related links, collections and Markdown revisions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Cards retain identity when retitled or moved; a collection membership change cannot delete the underlying note.
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. Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.
4. Phase 4 — Permissions and integration failure. Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Remove a card from a collection and still find it in search; export/import preserves the card graph without duplicate IDs. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Remove a card from a collection and still find it in search; export/import preserves the card graph without duplicate IDs.
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 Supernotes

## Project scope
Capture compact note cards, connect them with explicit links and browse a focused collection view. Search quickly and export each card with its links and original creation metadata.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Supernotes, capture small linked cards, tag them, and review or share focused collections. The hard boundary is real-time collaboration, mobile polish, sync, and card-based workflow refinement, plus sync, collaboration, and capture polish.
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
- Node and the Rust toolchain, a supported desktop build environment and an explicitly selected data folder. Remote sync is outside the initial scope.
- Implementation components: Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge. SQLite for structured state and search; user-owned files for original documents and attachments.
- Scope boundary: real-time collaboration, mobile polish, sync, and card-based workflow refinement; frictionless mobile capture

## Stack and architecture
- Tauri, React and TypeScript for the desktop interface with a narrowly scoped Rust filesystem bridge.
- SQLite for structured state and search; user-owned files for original documents and attachments.
- Domain model: note cards, stable card IDs, tags, parent/related links, collections and Markdown revisions

## Security and data integrity
- Limit Tauri capabilities to selected folders and commands. Render imported content without executable HTML, and never expose arbitrary shell execution to the webview.
- Correctness boundary: Cards retain identity when retitled or moved; a collection membership change cannot delete the underlying note.
- Save edits atomically with stable IDs and revision history. Detect external file changes and offer a conflict copy instead of last-write-wins data loss.
- Provide a portable folder export with a JSON manifest and original files. Restore to a separate folder; rebuild disposable indexes from sources.

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 Supernotes-inspired workflow with owned or clearly labeled sample data: Capture compact note cards, connect them with explicit links and browse a focused collection view. Search quickly and export each card with its links and original creation metadata.
- Publish a reproducible walkthrough with this observable result: Remove a card from a collection and still find it in search; export/import preserves the card graph without duplicate IDs.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: real-time collaboration, mobile polish, sync, and card-based workflow refinement; frictionless mobile capture Avoid guaranteed savings, performance scores or implied endorsement.

## 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.
