Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

add-operation 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 6d 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.

Add Operations — Sylius Stack

Ask the user for the ModelName and the list of operations they want if not provided. Several operations can be added in one run.

Supported operations:

Operation Route Method Notes
Index /{plural} GET requires a grid (run /sylius-stack:add-grid first)
Show /{plural}/{id} GET also scaffolds a minimal Twig Hook template
Create /{plural}/new GET, POST needs formType on the resource
Update /{plural}/{id}/edit GET, PUT, PATCH needs formType on the resource
Delete /{plural}/{id} DELETE
BulkDelete /{plural}/bulk_delete DELETE
ApplyStateMachineTransition /{plural}/{id}/{transition} GET requires a transition name

1. Read the entity

Read src/Entity/{ModelName}.php to locate the #[AsResource(...)] attribute and find:

  • Existing imports from Sylius\Resource\Metadata\*
  • Existing operations: [...] array (may be missing if this is the first call)

2. Ordering rule

When writing the operations array, place Create before any operation whose path starts with {id} (Show, Update, Delete). The Symfony router matches routes in the order they are registered, so a path like /{id} declared before /new can swallow the literal new.

Recommended order when all are present:

operations: [
    new Index(grid: Admin{ModelName}Grid::class),
    new Create(),
    new Update(),
    new Delete(),
    new BulkDelete(),
    new Show(),
],

3. Add imports

For each operation added, add its use statement if not already present:

use Sylius\Resource\Metadata\ApplyStateMachineTransition;
use Sylius\Resource\Metadata\BulkDelete;
use Sylius\Resource\Metadata\Create;
use Sylius\Resource\Metadata\Delete;
use Sylius\Resource\Metadata\Index;
use Sylius\Resource\Metadata\Show;
use Sylius\Resource\Metadata\Update;

For Index, also add:

use App\Grid\Admin{ModelName}Grid;

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.
