PastePal

Build the following focused alternative to PastePal. Implement the focused workflow below first; the verdict is not evidence of a completed or production-certified build.

WORKING SLICE
Capture a bounded local clipboard history, organize pinned items into collections and paste a reviewed item using keyboard controls.

SETUP AND ARCHITECTURE
Use Swift, SwiftUI/AppKit and SQLite on macOS, with secrets in Keychain where needed. Prerequisites: A Mac, the current Xcode toolchain and a documented permission checklist; distribution signing is a separate delivery task. Before integrating anything, record actual versions and permissions, plus model files or provider limits only where used, in the README; make unavailable dependencies visible rather than simulating success.

DOMAIN MODEL AND INVARIANTS
Store ClipboardItem, Collection, SourceAppRule and RetentionPolicy; never record concealed clipboard types, deduplicate repeated copies and keep pinning separate from retention eligibility.

IMPLEMENTATION CONTRACT
Ask for each operating-system permission when its feature is used. Handle denial and revocation without a loop; show permission status and keep local history deletable. Provide an input/setup view, the main work view, and a review/export view appropriate to this workflow. Preserve the last saved state if a job or save fails. Include empty, loading, permission-denied, partial and retryable-error states. Log identifiers and error categories without secret values or unnecessary private content.

APP-SPECIFIC BOUNDARY AND RECOVERY
Use a normal paste/clipboard fallback when Accessibility permission is absent. Do not promise universal password detection or encrypted history without implementing and documenting it.

ACCEPTANCE SCENARIO
Copy a secret from an excluded app, then a large image and repeated text; exclude the secret, enforce size caps and retain one searchable text item. Also reopen the app after an interrupted operation, confirm the saved record/export remains inspectable, and document the recovery action. These are implementation acceptance requirements, not a claim that this guide has been tested.

DELIVERY
Deliver a runnable repository with migrations or project-format versioning, a non-sensitive example, environment/permission setup, the exact manual acceptance steps, and a backup/export-and-restore walkthrough. Implement the working slice before optional integrations; list any deferred paid-product capabilities honestly. Do not add capabilities outside the working slice just to resemble the original product.

PROJECT RULES FOR AGENTS.md
Keep the domain invariants above executable at the write boundary. Propose scope changes before adding providers or permissions. Never fabricate source evidence, publish results, identity matches or successful delivery. Preserve user originals and require an explicit confirmation for destructive changes or external publication.

# AGENTS.md — Build guide for PastePal

## Project scope
Capture a bounded local clipboard history, organize pinned items into collections and paste a reviewed item using keyboard controls.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For PastePal, keep a local clipboard history with collections, search, and sensitive-item rules. The hard boundary is native apple apps, icloud sync, rich content support, and polish, plus os integration polish and maintenance.
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
- Runtime and tools: Swift, SwiftUI/AppKit and SQLite on macOS, with secrets in Keychain where needed.
- Before starting: A Mac, the current Xcode toolchain and a documented permission checklist; distribution signing is a separate delivery task.

## Stack and architecture
- Swift, SwiftUI/AppKit and SQLite on macOS, with secrets in Keychain where needed
- Data design: Store ClipboardItem, Collection, SourceAppRule and RetentionPolicy; never record concealed clipboard types, deduplicate repeated copies and keep pinning separate from retention eligibility.
- Setup: A Mac, the current Xcode toolchain and a documented permission checklist; distribution signing is a separate delivery task

## Security and data integrity
- Ask for each operating-system permission when its feature is used. Handle denial and revocation without a loop; show permission status and keep local history deletable.
- Use a normal paste/clipboard fallback when Accessibility permission is absent. Do not promise universal password detection or encrypted history without implementing and documenting it.
- Keep secrets outside client bundles and exported projects; document what leaves the device and make retention/deletion controls visible.

## Agent implementation rules
- Project rule — domain: Store ClipboardItem, Collection, SourceAppRule and RetentionPolicy; never record concealed clipboard types, deduplicate repeated copies and keep pinning separate from retention eligibility.
- Project rule — scope and recovery: Use a normal paste/clipboard fallback when Accessibility permission is absent. Do not promise universal password detection or encrypted history without implementing and documenting it.
- Project rule — acceptance: Copy a secret from an excluded app, then a large image and repeated text; exclude the secret, enforce size caps and retain one searchable text item.
- Project rule — delivery: document real setup commands and permissions; do not claim a build, accuracy level, performance result or security certification that has not been demonstrated.

## Optional agent skills and references
- Recommended skill: [swiftui-expert-skill](https://github.com/AvdLee/SwiftUI-Agent-Skill/blob/main/skills/swiftui-expert-skill/SKILL.md) — design native SwiftUI state, accessible controls and permission/error views for the proposed Apple-platform interface. Follow the maintainer's installation instructions and match its requirements to the chosen runtime.
- Recommended skill: [swift-concurrency](https://github.com/AvdLee/Swift-Concurrency-Agent-Skill/blob/main/skills/swift-concurrency/SKILL.md) — isolate capture, background work and UI updates, and make cancellation invalidate late callbacks. Follow the maintainer's installation instructions and match its requirements to the chosen runtime.

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 this working slice using synthetic or explicitly authorized non-sensitive examples: Capture a bounded local clipboard history, organize pinned items into collections and paste a reviewed item using keyboard controls.
- Share a synthetic example export and the acceptance walkthrough; keep real customer, health, financial and source data private: Copy a secret from an excluded app, then a large image and repeated text; exclude the secret, enforce size caps and retain one searchable text item.
- State the limits before asking someone to replace their existing tool: Use a normal paste/clipboard fallback when Accessibility permission is absent. Do not promise universal password detection or encrypted history without implementing and documenting it.

## Engineering roadmap
1. Phase 1 — Pin the working slice and create its example input: Capture a bounded local clipboard history, organize pinned items into collections and paste a reviewed item using keyboard controls. Confirm setup: A Mac, the current Xcode toolchain and a documented permission checklist; distribution signing is a separate delivery task.
2. Phase 2 — Implement persistence and write-time invariants before decorating the UI: Store ClipboardItem, Collection, SourceAppRule and RetentionPolicy; never record concealed clipboard types, deduplicate repeated copies and keep pinning separate from retention eligibility.
3. Phase 3 — Connect the working view to real saved state. Ask for each operating-system permission when its feature is used. Handle denial and revocation without a loop; show permission status and keep local history deletable.
4. Phase 4 — Expose the app-specific limits and recovery path in context: Use a normal paste/clipboard fallback when Accessibility permission is absent. Do not promise universal password detection or encrypted history without implementing and documenting it.
5. Phase 5 — Walk through this concrete acceptance case and preserve its exported evidence: Copy a secret from an excluded app, then a large image and repeated text; exclude the secret, enforce size caps and retain one searchable text item. Finish the README and backup/restore instructions; report unfinished capabilities explicitly.

## Paid-product capabilities outside this build
- native Apple apps, iCloud sync, rich content support, and polish
- years of OS-version edge cases
- large extension ecosystem

## 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.
