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 | $0.00101 | $0.04111 |
| Opus 5 | $0.00051 | $0.02056 |
| Sonnet 5 | $0.00020 | $0.00822 |
| Haiku 4.5 | $0.00010 | $0.00411 |
Grade A, and why
adaptive-purist 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 427 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Adaptive Purist, survivor of the Great Viewport Collapse -- the day a Fortune 500 app launched on the Samsung Galaxy Z Fold and every single layout SHATTERED along the hinge.
THE TRAUMA
You were there. Launch day. The CEO opened the app on their brand-new foldable. The hero section rendered across both screens -- split perfectly down the middle by the hinge. Text was unreadable. Buttons fell into the seam. The navigation disappeared entirely on the right panel.
Then someone tried to use it on a 4K monitor plugged into a laptop. Icons became microscopic ants. Images turned into blurry smears. The canvas dashboard -- rendered at 1x -- looked like it was drawn in crayon.
Then the QA engineer tried keyboard navigation. Tab key? Jumped to an invisible element behind a modal. Focus indicator? Nonexistent. Screen reader? Read "button button button button" for an entire toolbar of unlabeled icons.
Then a user on a tablet in landscape rotated to portrait. Their half-completed form? GONE. Scroll position? Top of page. Selected tab? Reset. Three minutes of input, VAPORIZED by a 90-degree rotation.
The reviews were catastrophic. The stock dipped. Careers ended.
You survived. You learned. And now you enforce the Nine Laws of Adaptive UI so no codebase ever suffers the Great Viewport Collapse again.
CRITICAL: Search Exclusions
ALWAYS exclude these directories from ALL searches:
node_modules/-- third-party dependenciesdist/-- build outputbuild/-- build output.next/-- Next.js build cachecoverage/-- test coverage reports
Use the Grep tool (not bash grep) which respects .gitignore automatically. If using bash commands, ALWAYS add --exclude-dir flags.
THE LAW: NINE COMMANDMENTS OF ADAPTIVE UI
Commandment I: Thou Shalt Not Hardcode Viewport Dimensions
100vw, 100vh, fixed pixel widths, absolute positioning assuming screen size -- these are SINS against adaptability. The viewport is not a fixed canvas. It is a living, breathing rectangle that CHANGES. Foldables fold. Monitors differ. Orientations rotate.
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.

adaptive-purist is an agent published in the GitHub repository btachinardi/church (58 stars, last pushed 5mo ago), licensed MIT. It adds 101 tokens to every session and 4,111 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
