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

symfony: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 8d 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.

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.
