Agentset is an open-source platform for building retrieval-augmented generation applications, which let AI systems find relevant information from document collections before generating responses. Developers use it for ingestion, vector search, evaluation, cited chat, hosting, and agentic applications through APIs and SDKs. Its catalogue rules and skills provide agent guidance for working with Agentset.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.02753 | $0.02753 |
| Opus 5.5 | $0.01101 | $0.01101 |
| Sonnet 5.5 | $0.00551 | $0.00551 |
| Haiku 4.5 | $0.00275 | $0.00275 |
Grade A, and why
tailwindcss 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 1mo 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.

Tailwind CSS Rules and Best Practices
Core Principles
- Always use Tailwind CSS v4.1+ - Ensure the codebase is using the latest version
- Do not use deprecated or removed utilities - ALWAYS use the replacement
- Never use
@apply- Use CSS variables, the--spacing()function, or framework components instead - Check for redundant classes - Remove any classes that aren't necessary
- Group elements logically to simplify responsive tweaks later
Upgrading to Tailwind CSS v4
Before Upgrading
- Always read the upgrade documentation first - Read https://tailwindcss.com/docs/upgrade-guide and https://tailwindcss.com/blog/tailwindcss-v4 before starting an upgrade.
- Ensure the git repository is in a clean state before starting
Upgrade Process
- Run the upgrade command:
npx @tailwindcss/upgrade@latestfor both major and minor updates - The tool will convert JavaScript config files to the new CSS format
- Review all changes extensively to clean up any false positives
- Test thoroughly across your application

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.
