Alfred Powerpack

WORKING SLICE
Open an AppKit launcher with a global shortcut, search installed apps, then add opt-in clipboard history and snippet expansion. Workflow commands have a preview, selected working directory and per-command approval.

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

Architecture
- Swift, SwiftUI and focused AppKit integrations for a macOS utility.
- SQLite or Codable files for local settings and history; macOS Keychain for credentials.
- AppKit NSPanel, application bundle indexing and NSPasteboard APIs; approved workflow subprocesses use argument arrays.

Prerequisites and limits
macOS, Xcode and a selected deployment target. Ask for each OS permission only when its feature is enabled; code signing and distribution are separate release tasks.
Outside this release: years of macOS integration, workflow ecosystem, reliability, and community; years of OS-version edge cases

Data model and correctness
indexed applications, ranked matches, clipboard entries, snippets and allowlisted workflow definitions
Invariant: Secure clipboard types and excluded applications never enter history; arbitrary imported workflows do not execute on installation.
Keep UI state on the main actor, cancel obsolete background tasks, and avoid blocking system callbacks. Record only the selected feature scope, with clear retention controls.

Security and privacy
Start capture or automation paused. Respect denied permissions, exclude secure fields and sensitive applications, and expose a visible pause/stop control.

Recovery and export
Export settings and explicitly selected history without secrets. Preserve the last working configuration and provide a reset that does not delete user source files.

Implementation order
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Open an AppKit launcher with a global shortcut, search installed apps, then add opt-in clipboard history and snippet expansion. Workflow commands have a preview, selected working directory and per-command approval. Record prerequisites, select representative user-owned fixtures and document the unsupported features: years of macOS integration, workflow ecosystem, reliability, and community; years of OS-version edge cases
2. Phase 2 — Durable model. Model indexed applications, ranked matches, clipboard entries, snippets and allowlisted workflow definitions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Secure clipboard types and excluded applications never enter history; arbitrary imported workflows do not execute on installation.
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. Keep UI state on the main actor, cancel obsolete background tasks, and avoid blocking system callbacks. Record only the selected feature scope, with clear retention controls.
4. Phase 4 — Permissions and integration failure. Start capture or automation paused. Respect denied permissions, exclude secure fields and sensitive applications, and expose a visible pause/stop control. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export settings and explicitly selected history without secrets. Preserve the last working configuration and provide a reset that does not delete user source files. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Denied Accessibility permission still permits app search; copying a password-manager concealed item leaves no history entry, and a stale snippet trigger cannot paste into another app. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

Acceptance
Denied Accessibility permission still permits app search; copying a password-manager concealed item leaves no history entry, and a stale snippet trigger cannot paste into another app.
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 Alfred Powerpack

## Project scope
Open an AppKit launcher with a global shortcut, search installed apps, then add opt-in clipboard history and snippet expansion. Workflow commands have a preview, selected working directory and per-command approval.

Catalogue verdict: yes. The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Alfred Powerpack, build a local launcher with search, snippets, clipboard history, and workflows. The hard boundary is years of macos integration, workflow ecosystem, reliability, and community, 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
- macOS, Xcode and a selected deployment target. Ask for each OS permission only when its feature is enabled; code signing and distribution are separate release tasks.
- Implementation components: Swift, SwiftUI and focused AppKit integrations for a macOS utility. SQLite or Codable files for local settings and history; macOS Keychain for credentials. AppKit NSPanel, application bundle indexing and NSPasteboard APIs; approved workflow subprocesses use argument arrays.
- Scope boundary: years of macOS integration, workflow ecosystem, reliability, and community; years of OS-version edge cases

## Security and data integrity
- Start capture or automation paused. Respect denied permissions, exclude secure fields and sensitive applications, and expose a visible pause/stop control.
- Correctness boundary: Secure clipboard types and excluded applications never enter history; arbitrary imported workflows do not execute on installation.
- Keep UI state on the main actor, cancel obsolete background tasks, and avoid blocking system callbacks. Record only the selected feature scope, with clear retention controls.
- Export settings and explicitly selected history without secrets. Preserve the last working configuration and provide a reset that does not delete user source files.

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 Alfred Powerpack-inspired workflow with owned or clearly labeled sample data: Open an AppKit launcher with a global shortcut, search installed apps, then add opt-in clipboard history and snippet expansion. Workflow commands have a preview, selected working directory and per-command approval.
- Publish a reproducible walkthrough with this observable result: Denied Accessibility permission still permits app search; copying a password-manager concealed item leaves no history entry, and a stale snippet trigger cannot paste into another app.
- Explain who can operate this scoped tool, its setup and ongoing costs, and these remaining product gaps: years of macOS integration, workflow ecosystem, reliability, and community; years of OS-version edge cases Avoid guaranteed savings, performance scores or implied endorsement.

## Engineering roadmap
1. Phase 1 — Scope and fixtures. Implement this bounded workflow: Open an AppKit launcher with a global shortcut, search installed apps, then add opt-in clipboard history and snippet expansion. Workflow commands have a preview, selected working directory and per-command approval. Record prerequisites, select representative user-owned fixtures and document the unsupported features: years of macOS integration, workflow ecosystem, reliability, and community; years of OS-version edge cases
2. Phase 2 — Durable model. Model indexed applications, ranked matches, clipboard entries, snippets and allowlisted workflow definitions Add migrations or a versioned document format, explicit validation, stable IDs and a visible import-error report. Preserve this rule: Secure clipboard types and excluded applications never enter history; arbitrary imported workflows do not execute on installation.
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. Keep UI state on the main actor, cancel obsolete background tasks, and avoid blocking system callbacks. Record only the selected feature scope, with clear retention controls.
4. Phase 4 — Permissions and integration failure. Start capture or automation paused. Respect denied permissions, exclude secure fields and sensitive applications, and expose a visible pause/stop control. Request integration credentials and permissions only for the enabled feature; show a disconnected state instead of mock results.
5. Phase 5 — Portable handoff. Export settings and explicitly selected history without secrets. Preserve the last working configuration and provide a reset that does not delete user source files. Include setup, operating limits, fixture walkthrough and shutdown/restart instructions in the README.
6. Phase 6 — Acceptance scenarios. Denied Accessibility permission still permits app search; copying a password-manager concealed item leaves no history entry, and a stale snippet trigger cannot paste into another app. Repeat the workflow after restart and with a denied permission or unavailable dependency; show recoverable failure rather than a success placeholder.

## 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.
