Apply Hexagonal Architecture / Ports & Adapters in Symfony — Domain (POPOs, no framework imports), Application (use cases orchestrating ports), Infrastructure (Symfony / Doctrine / API Platform adapters). Bounded contexts variant: one context per business domain with a `Contract/` public surface. Deptrac to enforce layer boundaries in CI. Custom PHPStan rules to encode ADRs (no `EntityManager` in Provider, command DTOs `final readonly`). Trigger on "decouple domain from framework", "introduce bounded contexts", or "enforce architectural boundaries".

The file

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈4

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Use existing project patterns by default.

    line 24
  2. Distinctive:

    Avoid broad refactors without explicit need.

    line 25
  3. Distinctive:

    Keep decision log clear and auditable.

    line 26
  4. Distinctive:

    Use this file for execution posture and risk controls.

    line 29

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Ports And Adapters (Symfony)

Use when

  • Refining architecture/workflows/context handling in Symfony projects.
  • Planning and executing medium/complex changes safely.

Default workflow

  1. Establish current boundaries, constraints, and coupling points.
  2. Propose smallest coherent architectural adjustment.
  3. Execute in checkpoints with validation at each stage.
  4. Summarize tradeoffs and follow-up backlog.

Guardrails

  • Use existing project patterns by default.
  • Avoid broad refactors without explicit need.
  • Keep decision log clear and auditable.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • Architecture/workflow changes.
  • Checkpoint validation outcomes.
  • Residual risks and next steps.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
