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 | $0.00119 | $0.00582 |
| Opus 5 | $0.00060 | $0.00291 |
| Sonnet 5 | $0.00024 | $0.00116 |
| Haiku 4.5 | $0.00012 | $0.00058 |
Grade A, and why
hwc-forms-validation 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 13d 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
Forms & Validation
Implement form-centric Hotwire workflows with Turbo Frames and Stimulus.
Core Workflow
- Identify the form flow: create/edit, inline edit, typeahead, modal form, or external controls.
- Wrap the form interaction scope in a Turbo Frame when validation errors must rerender in place.
- Return
422for validation failures and303for successful redirects. - Handle post-submit behavior with
turbo:submit-endonly when Turbo defaults are insufficient. - Preserve user context during rerenders (focus/caret/selection).
Guardrails
- Keep one source of truth for input state; avoid duplicate controls across frame and non-frame DOM.
- Use the HTML
formattribute for controls rendered outside the target<form>hierarchy. - Avoid firing submit logic on every keystroke without debounce/throttle.
- Keep post-submit behavior explicit when form responses update only a frame.

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.
