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 | $0.00000 | $0.00201 |
| Opus 5 | $0.00000 | $0.00101 |
| Sonnet 5 | $0.00000 | $0.00040 |
| Haiku 4.5 | $0.00000 | $0.00020 |
Grade A, and why
buildable-preview 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 6d 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
Buildable Preview
Render the running prototype in a headless browser, screenshot it, and catch runtime/visual errors.
Start the dev server (e.g. npm run dev), then run:
buildable preview --url http://localhost:3000 2>/dev/null || node "${BUILDABLE_ROOT:?Set BUILDABLE_ROOT to your Buildable checkout}/bin/buildable.mjs" preview --url http://localhost:3000
If buildable is not globally linked, set BUILDABLE_ROOT to the local Buildable checkout. Needs Playwright (npm i -D playwright && npx playwright install chromium); if it reports skipped, install it or use your own screenshot tool. Open .buildable/preview.png and .buildable/preview-report.md, confirm the first screen looks intentional (visible actions, real data, good empty states, no blank render), fix what the screenshot reveals, and re-run until it passes.
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.
