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.

A single operations cockpit for Capell that surfaces system health, queue activity, config drift, permission audits, and per-package install health - with a guarded command palette for trusted capell:* operations.

After install, admins get package-owned management or reporting surfaces inside Capell.

Why It Matters

For developers: The package gives developers package-owned service providers, Actions, Data objects, models, Filament classes, and Blade views instead of pushing this behaviour into core or application code.

For teams: A single operations cockpit for Capell that surfaces system health, queue activity, config drift, permission audits, and per-package install health - with a guarded command palette for trusted capell:* operations.

Data Model

Required tables: command_palette_runs, queue_monitors, diagnostics_health_snapshots.
Models: CommandPaletteRun, DiagnosticsHealthSnapshot, FailedJob, PendingQueueJob, QueueMonitor.
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.
Migration impact: run host migrations through the package install flow before opening package surfaces.
Deletion/retention behaviour: Docs gap unless the package has an explicit pruning command, retention setting, or tested cascade path.

Install Impact

Admin navigation: adds package-owned Filament classes when registered.
Permissions: accessDiagnostics, viewDiagnostics, View:PermissionAuditPage, View:CommandPalettePage, View:QueueHealthPage, Manage:QueueHealthPage.
Public routes: none detected in package route files.
Database changes: package migrations are declared.
Settings: no package settings declared.
Queues or schedules: none detected in standard package paths.
Cache tags: diagnostics.
Commands: capell:diagnostics:health.

Common Pitfalls

Run migrations before opening package resources or public routes.
Run package commands from the host app; in this repository use vendor/bin/pest for package tests.
Keep composer.json, composer.local.json, capell.json, docs, screenshots, and tests aligned when the package surface changes.

Troubleshooting

Symptom	Likely cause	Check	Fix
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 scheduled command is not active	Check package jobs, commands, and host scheduler configuration	Start the queue or scheduler, then run the focused command or package test

Quick Start

Install the package: composer require capell-app/diagnostics.
Run the required setup: php artisan migrate.
Open the related Capell admin surface and verify Diagnostics appears.
