doctrine-relations

doctrine-relations is a skill for Claude Code from gerard-labs/superpowers-api-platform. It costs 102 tokens per session (302 once invoked), scanned A, a copy of symfony:doctrine-relations, MIT.

A Symfony and Doctrine skill for defining how database records relate to one another, such as one-to-many or many-to-many relationships. It also covers which side owns a relationship, deletion behavior, indexes, and loading choices.

In plain words
What is it for?
Use it when modeling entity relationships, adding constraints and indexes, choosing cascade or orphan-removal behavior, and deciding how related records are loaded.
Why use it?
It helps prevent inconsistent relationships, accidental record deletion, slow queries, and unnecessary database work. The guidance makes the database structure match the application's data model.

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

doctrine-relations 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 5d 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.

Origin

This is a copy

78% identical to symfony:doctrine-relations — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Doctrine Relations (Symfony)

Use when

  • Designing entity relations or schema evolution.
  • Improving Doctrine correctness/performance.

Default workflow

  1. Model ownership/cardinality and transactional boundaries.
  2. Apply mapping/schema changes with migration safety.
  3. Tune fetch/query behavior for hot paths.
  4. Verify lifecycle behavior with targeted tests.

Guardrails

  • Keep owning/inverse sides coherent.
  • Avoid destructive migration jumps in one release.
  • Eliminate accidental N+1 and over-fetching.

Progressive disclosure

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

Output contract

  • Entity/migration changes.
  • Integrity and performance decisions.
  • Validation outcomes and rollback notes.

References

  • reference.md
  • docs/complexity-tiers.md
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
