> ## Agent Instructions
> Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request.
> Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance.
> For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code.
> The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust.
> Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.
> Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name <name> --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first. Task map: https://phaseo.app/docs/v1/developers/manage-from-an-agent.md.

# Review CMS content with the PHP Agent SDK

> Use the PHP Agent SDK to wrap one local content lookup tool in a bounded review loop.

Use this recipe when a PHP app or admin backend needs quick content review help without offloading orchestration elsewhere.

## 1. Prepare the SDKs

> [!NOTE]
>
> The PHP Agent SDK package is not yet on Packagist. Follow the [source installation instructions](https://phaseo.app/docs/v1/sdk-reference/php/agent-sdk-installation.md).

## 2. Define one content lookup tool

```php theme={null}
<?php
use Phaseo\AgentSdk\AgentSdk;
use Phaseo\AgentSdk\Tool;

$loadDraft = AgentSdk::defineTool(new Tool(
    id: "load-draft",
    description: "Load one CMS draft by slug.",
    parameters: [
        "type" => "object",
        "properties" => [
            "slug" => ["type" => "string"],
        ],
        "required" => ["slug"],
    ],
    execute: static fn (mixed $input, $context) => [
        "slug" => $input["slug"] ?? "homepage",
        "headline" => "Phaseo makes gateway routing visible.",
    ]
));
```

## 3. Create and run the agent

```php theme={null}
<?php
use Phaseo\AgentSdk\AgentDefinition;

$agent = AgentSdk::createAgent(new AgentDefinition(
    id: "content-review-agent",
    model: "openai/gpt-5.4-nano",
    instructions: "Use tools when helpful and return concise editorial feedback.",
    tools: [$loadDraft]
));

$result = $agent->run(
    input: "Review the homepage draft and suggest one headline improvement.",
    client: AgentSdk::createGatewayAgentClient()
);

echo $result->output . PHP_EOL;
```

## When this recipe fits

* the PHP app already owns the content source
* one or two local tools are enough
* you want a bounded loop rather than a broader orchestration platform
