What This Plugin Adds

Diagnostics is an Available, Schema-owning Capell package in the Capell Operations product group. It ships as capell-app/diagnostics and extends these surfaces: admin, console.

Diagnostics adds package, configuration, cache, content, permission, and queue health reporting plus a guarded command palette for trusted operations.

Operators inspect health widgets and focused report pages, investigate queue failures, and run permitted diagnostic commands with recorded parameters and output.

Status details:

• Status: Available
• Tier: premium
• Bundle: operations
• Composer package: capell-app/diagnostics
• Namespace: Capell\Diagnostics
• Theme key: not applicable

Why It Matters

For developers: Each health signal and command operation is isolated in an Action or provider, including parameter validation and output redaction before a run is stored.

For teams: Teams get a shared view of operational problems and enough context to route content, configuration, permission, or queue issues to the right owner.

Cache tags

Data Model

• Required tables: command_palette_runs, queue_monitors, diagnostics_health_snapshots.
• Models: CommandPaletteRun, DiagnosticsHealthSnapshot, FailedJob, PendingQueueJob, QueueMonitor.
• Core record references in migrations: users via user_id.
• Migration files: 2026_05_10_190846_01_create_command_palette_runs_table.php, 2026_05_29_000001_create_queue_monitors_table.php, 2026_06_07_000001_create_diagnostics_health_snapshots_table.php, 2026_07_10_000001_encrypt_command_palette_parameters.php, 2026_09_29_120000_remove_implicit_timestamp_updates_from_diagnostics.php.
• Migration impact: run host migrations through the package install flow before opening package surfaces.
• Deletion/retention behaviour: migrations declare null-on-delete relationships; retention is scheduled through capell:diagnostics:prune (daily; declared in the manifest).

Install Impact

• Required packages: capell-app/admin, capell-app/core, capell-app/html-cache.
• Admin navigation: declares admin-page: CommandPalettePageContribution, admin-page: DiagnosticsPageContribution, admin-page: PermissionAuditPageContribution, admin-page: QueueHealthPageContribution, admin-page: SystemHealthPageContribution; each Filament page or resource controls its own navigation visibility.
• Admin/editor extensions: dashboard-widget: SiteHealthWidgetContribution, dashboard-widget: SystemHealthWidgetsContribution.
• Permissions: View:DiagnosticsPage, Execute:DiagnosticsPage, View:PermissionAuditPage, View:CommandPalettePage, Execute:CommandPalettePage, View:SystemHealthPage, View:QueueHealthPage, Execute:QueueHealthPage, Delete:QueueHealthPage.
• Public routes: none declared.
• Database changes: package migrations are declared.
• Config: config/capell-diagnostics.php.
• Settings: no package settings declared.
• Queues or schedules: scheduled commands capell:diagnostics:prune (daily; manifest declared); queue jobs RunCommandPaletteArtisanJob.
• Cache tags: diagnostics.
• Commands: capell:diagnostics:health, capell:diagnostics:prune.

Common Pitfalls

• Keep required Capell packages on compatible v4 releases: capell-app/admin, capell-app/core, capell-app/html-cache.
• Run migrations before opening package resources or public routes.
• Review package configuration before production-like verification: config/capell-diagnostics.php.
• Keep the host Laravel scheduler running so package-registered schedules can execute: capell:diagnostics:prune (daily; manifest declared).
• Custom write integrations must preserve invalidation for diagnostics cache tags.

Troubleshooting

Symptom	Likely cause	Check	Fix
Package health check reports a problem	Package configuration or runtime dependencies are not ready	Run php artisan capell:diagnostics:health	Follow the reported checks, then rerun the doctor command
Package surface is missing after install	Provider or manifest is not loaded	Confirm capell.json, package composer.json, and provider registration	Reinstall the package, refresh Composer autoload, and clear host caches
Admin screen or command fails on missing table	Package migrations have not run	Check the tables listed in Data Model	Run host migrations and rerun the focused package test
Background work does not run	Queue worker or declared schedule is not active	Check the jobs and scheduled commands listed in Technical Shape	Start the queue worker or host scheduler, then run the focused command or package test

Quick Start

1. Install the package: composer require capell-app/diagnostics.
2. Open the package admin surface at /admin/diagnostics and confirm Diagnostics is available.
