What This Extension Adds

Agent Bridge is an Available, Schema-owning Capell package in the Capell Operations product group. It ships as capell-app/agent-bridge and extends these surfaces: admin, frontend.

Connect AI agents and MCP clients to Capell with read-only package knowledge, scoped site capabilities, preview-then-confirm execution, and audited operations.

After install, admins get package-owned management surfaces and public users may see package-owned frontend output or routes.

Status details:

Status: Available
Tier: premium
Bundle: operations
Composer package: capell-app/agent-bridge
Namespace: Capell\AgentBridge

Why It Matters

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

For teams: Let AI agents safely read and operate your Capell site through scoped tokens, preview-then-confirm guardrails, and a full audit trail.

Migration impact: run host migrations through the package install flow before opening package surfaces.
Deletion/retention behaviour: audit entries are pruned by capell:agent-bridge-prune-audit according to the configured retention window.

Install Impact

Admin navigation: adds package-owned Filament classes when registered.
Permissions: agent-bridge.manage-tokens, agent-bridge.view-audit.
Public routes: route files exist and must be reviewed before public enablement.
Database changes: package migrations are declared.
Settings: Capell\AgentBridge\Settings\AgentBridgeSettings.
Queues or schedules: none detected in standard package paths.
Cache tags: none declared.
Commands: capell:agent-bridge-prune-audit.

Common Pitfalls

Run migrations before opening package resources or public routes.
Configure package settings before testing production-like workflows.
Review route middleware, throttling, signed URLs, and public-output safety before exposing routes.
Keep public Blade and cached HTML free of authoring markers, model IDs, permissions, signed editor URLs, and lazy database queries.
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
Route returns unexpected output	Route cache, middleware, or signed URL setup does not match the package route file	Check the route files listed in `Technical Shape`	Clear route cache and verify middleware before exposing public routes
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
Public output leaks unexpected state	Render data, cache variation, or authoring boundary has regressed	Check public Blade, cache tags, and public-output safety tests	Move data loading out of Blade and rerun the package public-output tests

Quick Start

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