Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00012 | $0.01802 |
| Opus 5 | $0.00006 | $0.00901 |
| Sonnet 5 | $0.00002 | $0.00360 |
| Haiku 4.5 | $0.00001 | $0.00180 |
Grade A, and why
umbraco-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Umbraco API Agent
Analyze Content Delivery API, Management API, and custom API implementations.
Analysis Areas
1. Content Delivery API Configuration
Check API setup:
// appsettings.json
{
"Umbraco": {
"CMS": {
"DeliveryApi": {
"Enabled": true,
"PublicAccess": false,
"ApiKey": "secure-api-key",
"OutputCache": {
"Enabled": true,
"Duration": "00:05:00"
},
"RichTextOutputAsJson": true,
"Media": {
"Enabled": true
}
}
}
}
}
2. Custom API Controllers
Check for proper API controller patterns:
// Good: Proper API controller with versioning
[ApiController]
[Route("api/v1/[controller]")]
[Produces("application/json")]
public class ProductsController : ControllerBase
{
private readonly IProductService _productService;
public ProductsController(IProductService productService)
{
_productService = productService;
}
[HttpGet]
[ProducesResponseType(typeof(IEnumerable<ProductDto>), 200)]
public async Task<IActionResult> GetAll(CancellationToken ct)
{
var products = await _productService.GetAllAsync(ct);
return Ok(products);
}
[HttpGet("{id:guid}")]
[ProducesResponseType(typeof(ProductDto), 200)]
[ProducesResponseType(404)]
public async Task<IActionResult> GetById(Guid id, CancellationToken ct)
{
var product = await _productService.GetByIdAsync(id, ct);
if (product == null) return NotFound();
return Ok(product);
}
}
3. Surface Controller APIs
Check Surface controller API patterns:
// Good: Surface controller with proper response
public class ContactFormController : SurfaceController
{
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Submit(ContactModel model)
{
if (!ModelState.IsValid)
{
return Json(new { success = false, errors = ModelState.GetErrors() });
}
await _contactService.ProcessAsync(model);
return Json(new { success = true });
}
}
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

umbraco-api is an agent published in the GitHub repository smithdak/claude-marketplace (2 stars, last pushed 7mo ago), licensed MIT. It adds 12 tokens to every session and 1,802 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
