Phase 4 Plan 02: Script Generator (Uninstall + Detect + API) Summary

Jinja2 uninstall/detect templates, render_uninstall/render_detect functions, and three downloadable PS1 script endpoints wired to the scripts router

Performance

• Duration: ~2 min
• Started: 2026-04-10T11:33:58Z
• Completed: 2026-04-10T11:36:13Z
• Tasks: 2
• Files modified: 6

Accomplishments

• render_uninstall() produces Remove-Printer > Remove-PrinterDriver > Remove-PrinterPort with -ErrorAction SilentlyContinue (safe ordering)
• render_detect() follows Intune detection contract: Get-Printer check, Write-Output + exit 0 when found, exit 1 when absent
• Three GET endpoints /printers/{id}/scripts/{install,uninstall,detect} return PS1 scripts as file downloads
• Full error handling: 404 for missing printer, 422 for missing driver/INF/driver_desc
• Full test suite green: 75 tests (7 new tests added)

Task Commits

Each task was committed atomically:

1. Task 1 RED: Failing tests for render_uninstall/detect - 0f213df (test)
2. Task 1 GREEN: render_uninstall + render_detect + templates - 6bff8f3 (feat)
3. Task 2: Script API endpoints + router registration - b7b0d1b (feat)

Note: TDD task split into RED + GREEN commits per TDD protocol

Files Created/Modified

• imptune/templates/scripts/uninstall.ps1.j2 - PowerShell uninstall template (Remove-Printer/Driver/Port in order)
• imptune/templates/scripts/detect.ps1.j2 - PowerShell Intune detection template (Get-Printer + exit 0/1)
• imptune/generators/script_generator.py - Added render_uninstall() and render_detect() functions
• imptune/api/scripts.py - APIRouter with 3 script download endpoints, shared validation helper
• imptune/main.py - Registered scripts.router
• tests/test_script_generator.py - Added 2 unit tests + 5 integration tests

Decisions Made

• _get_printer_and_driver() private helper centralises 404/422 validation logic for all three endpoints — avoids repeating identical ORM+validation code 3 times
• PlainTextResponse with Content-Disposition: attachment; filename="{type}.ps1" on all endpoints so browsers download the file rather than rendering it
• Integration tests create ORM records directly via Driver.create()/Printer.create() — same established pattern as printer CRUD tests, no HTTP API calls for setup

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None - all tests passed on first run after implementation.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All three script types downloadable via API — ready for Phase 5 packaging
• render_install, render_uninstall, render_detect all available in script_generator module
• scripts.py router registered and functional
