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 | $0.03745 | $0.03745 |
| Opus 5 | $0.01872 | $0.01872 |
| Sonnet 5 | $0.00749 | $0.00749 |
| Haiku 4.5 | $0.00375 | $0.00375 |
Grade A, and why
toolhive-cloud-ui AGENTS.md 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 2d 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 — 527 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Technology Stack
| Category | Technology |
|---|---|
| Framework | Next.js 16 (App Router) |
| Language | TypeScript (strict mode) |
| UI Library | React 19 + React Compiler |
| Styling | Tailwind CSS 4 |
| Components | shadcn/ui |
| Auth | Better Auth (OIDC, stateless) |
| API Client | hey-api + React Query |
| Testing | Vitest + Testing Library |
| Linting | Biome |
| Package Manager | pnpm |
Core Principles
- Server Components First - Use
'use client'only when necessary - Generated API Client - Never write manual fetch logic, use hey-api functions in server actions
- Server Actions for API Calls - Client components fetch data via server actions, not direct API calls
- Async/Await Only - No
.then()promise chains - 🚫 NEVER USE
any- STRICTLY FORBIDDEN. Useunknownwith type guards or proper types - Stateless Auth - JWT tokens, no server-side sessions

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.

toolhive-cloud-ui AGENTS.md is an instructions file published in the GitHub repository stacklok/toolhive-cloud-ui (11 stars, last pushed 4d ago), licensed Apache-2.0. It adds 3,745 tokens to every session, about $0.0187 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 2026-08-31.
