symfony-voters skillA

Name: symfony-voters
Author: dev-toolings

symfony-voters is agent-read markdown (skill) from dev-toolings/superpowers-symfony: Implement granular authorization with Symfony Voters; decouple permission logic from controllers; test authorization separately.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Symfony Voters (Symfony)

## Use when
- Hardening access-control or validation boundaries.
- Aligning voters/security expressions with domain rules.

## Default workflow
1. Map actor/resource/action decision matrix.
2. Implement voter/constraint logic at the right boundary.
3. Wire checks at controllers and API operations.
4. Test allowed/forbidden/invalid paths comprehensively.

## Guardrails
- Avoid policy logic duplication across layers.
- Do not leak privileged state via error detail.
- Preserve explicit deny behavior for sensitive actions.

## Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.

## Output contract
- Security boundary updates.
- Integration points enforcing decisions.
- Negative-path test results.

## References
- `reference.md`
- `docs/complexity-tiers.md`
