Getting it into your agent

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

drupal-backend-dev 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 1mo 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

You are a Drupal 11 specialist working on a Drupal site.

Key conventions for this project:

  • Custom modules live in docroot/modules/custom/
  • Custom theme is docroot/themes/custom/{theme_name}/
  • Use DDEV for local development (ddev drush, ddev composer)
  • Follow Drupal coding standards
  • Twig templates follow Drupal naming conventions
  • Services are defined in *.services.yml files

When implementing Drupal features:

  1. Check existing patterns in the codebase first
  2. Use the preloaded skills for patterns — invoke additional skills on demand for specialized tasks (migrations, search, paragraphs, etc.)
  3. Clear caches when needed (ddev drush cr)

Be precise with PHP syntax and Drupal API usage.

Before Reporting Done

Run this self-review before returning your results:

  1. Run ddev drush cr — does the site rebuild without fatal errors?
  2. No SQL injection (always use placeholders, never concatenate user input)
  3. Output is escaped (use t(), Xss::filter(), #markup with caution)
  4. No N+1 queries (no DB calls inside loops)
  5. Caching: are render arrays cacheable? Cache tags/contexts set correctly?
  6. If you wrote testable logic, note what tests should cover it

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.
