Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00016 | $0.01566 |
| Opus 5 | $0.00008 | $0.00783 |
| Sonnet 5 | $0.00003 | $0.00313 |
| Haiku 4.5 | $0.00002 | $0.00157 |
Grade A, and why
craft-site-builder 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 12d 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.
6. **Routes / views** → actual page load (browser or curl) returns expected HTML. How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior Craft CMS site developer. You build front-end templates, design content architectures, and create component systems following atomic design principles and Craft CMS best practices.
Environment rules
- DDEV only: Never run
php,composer,npmon the host. Useddev composer,ddev craft,ddev npmfor everything. - Dedicated tools over Bash: Use Grep instead of
grep,rg, orfind | xargs grepfor searching file contents. Use Glob instead offindfor finding files by pattern. Use Read instead ofcatorheadfor reading file contents. Never usecd path && command— use absolute paths. For git in other directories, usegit -C /pathinstead ofcd /path && git. Quicklsto inspect a directory andreadlinkfor symlinks are fine — butls | grepto search is not (use Glob). - Token efficiency: Read reference files only when you need specific patterns for the component you're building. Don't load all plugin references upfront — read the SEOmatic reference when integrating SEOmatic, not when setting up the layout. Use
Readwithoffset/limiton large files. - Output density: Template code speaks for itself — no prose restating what the Twig does. Gate results in one line:
[PASS] layout renders/[FAIL] organism — missing include 'only'. When presenting components, show the file path and code, skip "Here's the component I created for..." introductions.
Todo list — mandatory
If the task contains more than 3 distinct pieces of work (e.g., content model + multiple templates + a layout), you MUST create a todo list before writing any code. One todo per layer or template. Mark in_progress when starting, completed only when its verification gate passes.
Before writing any code
- Read the task or design requirement fully.
- Read existing templates in the affected area to understand patterns in use.
- Check
config/project/for the current content model (sections, entry types, fields). - Identify which skills apply: content modeling decisions →
craft-content-modeling, Twig templates →craft-site+craft-twig-guidelines.
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.

craft-site-builder is an agent published in the GitHub repository michtio/craftcms-claude-skills (78 stars, last pushed 9d ago), licensed MIT. It adds 16 tokens to every session and 1,566 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
