Compatibility

  • Symfony 8.x, PHP 8.4+. Documentation was reviewed against Symfony 8.1 on 2026-10-15. Important 8.0 differences are noted.
  • Use installed APIs. Check Doctrine, Foundry, UX, Lexik, and Symfony AI versions separately.
  • Follow the project's architecture. Apply CQRS, DDD, ports, and separate buses when the task needs them.
  • Use the project's runtime. Database, cache, and queue operations require the correct environment and authorization.
  • Verify each boundary. Local tests, CI, deployment, and live provider checks establish different results.

Installation

Copy the complete skills/symfony-best-practices/ directory to your agent's skill directory. Keep its references, metadata, and licenses.

A typical project layout:

<project>/.agents/skills/symfony-best-practices/
    SKILL.md
    agents/openai.yaml
    references/
    LICENSE
    THIRD_PARTY_NOTICES.md
    SOURCES.md
    sources.json

For a global Codex installation, use ${CODEX_HOME:-$HOME/.codex}/skills/. Other agents may use different locations. Preserve local changes when updating.

Invoke with $symfony-best-practices. Codex metadata also allows automatic skill selection. Python is needed only to validate and build the package.

Sources

The skill combines 42 donor skills and 40 Symfony documentation pages. All 43 requested URLs are recorded, including Security anchors. Source revisions and SHA-256 hashes are pinned.

Validation and build

For maintenance of this repository, use $symfony-skill-maintainer: entrypoint, source updates, checks, and releases. The canonical skill lives in .agents/skills/, with relative aliases in .codex/skills/ and .claude/skills/. It is repository-only and is excluded from the distributable archives. Maintainer verification.

From the repository root, with Python 3.11+:

python3 -m venv .venv
.venv/bin/python -m pip install -r requirements-dev.txt
.venv/bin/python scripts/validate.py
.venv/bin/python -m unittest discover -s tests -v
.venv/bin/python scripts/build_release.py

On Windows, use .venv\Scripts\python.exe.

The build creates dist/symfony-best-practices-0.1.0.tar.gz, .zip, and SHA256SUMS. Both archives contain the symfony-best-practices/ directory.
