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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03589 | $0.03589 |
| Opus 5.5 | $0.01436 | $0.01436 |
| Sonnet 5.5 | $0.00718 | $0.00718 |
| Haiku 4.5 | $0.00359 | $0.00359 |
Grade A, and why
drupal-ai-agents CLAUDE.md scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 266 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Drupal AI Agents
Language
- User interaction: Respond in the same language the user writes in.
- Everything else in English: All code, variables, functions, comments, docblocks, commit messages, and generated content must always be in English.
- Skills and agents: Match the user's intent to the appropriate English-defined skill by semantic meaning, not literal keyword matching.
Design Principles
- Simple and elegant solutions first. Always prefer the simplest, cleanest approach. Avoid over-engineering.
DDEV Environment
You run inside an AI container (OpenCode or Claude Code). The project uses multiple DDEV containers:
| Container | Access method | Purpose |
|---|---|---|
| Your container | Direct | Agents, file access, bash |
Web (web) |
SSH | PHP, Drupal, Drush, Composer |
Beads (beads) |
bd wrapper |
Git-backed task tracking |
Playwright MCP ($PLAYWRIGHT_MCP_URL) |
HTTP MCP | Chromium browser testing |
All PHP/Drupal commands must use SSH:
ssh web drush cr
ssh web ./vendor/bin/phpstan analyse $DDEV_DOCROOT/modules/custom
ssh web ./vendor/bin/phpunit $DDEV_DOCROOT/modules/custom/mymodule
CRITICAL: Always use ssh web drush <command> to run Drush commands (the drush alias is available in the web container's PATH).
CRITICAL: Never hardcode web/ -- use $DDEV_DOCROOT (varies per project: web/, docroot/, etc.).
Available variables: $DDEV_PRIMARY_URL (HTTPS), $DDEV_HTTP_URL (HTTP — use for browser testing), $DDEV_SITENAME, $DDEV_DOCROOT, $PLAYWRIGHT_MCP_URL
Model Strategy
Agents use model tokens that resolve to real model names at sync time:
| Token | Default | Used for |
|---|---|---|
MODEL_MAIN |
CHEAP (OpenCode) / NORMAL (Claude Code) | The orchestrator: main conversation loop that receives prompts and delegates |
MODEL_GENIUS |
same as SMART | Hardest tasks: important code reviews, architecture decisions |
MODEL_SMART |
Opus 4.6 | Quality gates, planning, research, delegation advice |
MODEL_NORMAL |
Sonnet 4.5 | Development, review |
MODEL_CHEAP |
Haiku 4.5 | Exploration, fast tasks |
MODEL_APPLIER |
Haiku 4.5 | Mechanical code application |
MODEL_VISION |
same as NORMAL | Image/screenshot interpretation — must accept image input |
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.

drupal-ai-agents CLAUDE.md is an instructions file published in the GitHub repository trebormc/drupal-ai-agents (11 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 3,589 tokens to every session, about $0.0144 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
