Libra AI is an open-source web application builder that turns natural-language requests into applications and supports their development, deployment, and hosting. Developers use it as an alternative to tools such as V0 and Lovable, either through its hosted service or by running the source themselves. The catalogue includes rules and instructions for coding agents working with Libra AI.
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 | $0.00425 | $0.00425 |
| Opus 5.5 | $0.00170 | $0.00170 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
typescript 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.

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.

typescript is a cursor rule published in the GitHub repository nextify-limited/libra (1,685 stars, last pushed 1y ago), licensed AGPL-3.0. It adds 425 tokens to every session, about $0.0017 per session on Opus 5.5. A static security scan graded it A with 0 findings.

typescript-config
Shared TSConfig presets - preset table, deliberate omissions, typecheck model, editing rules, in-app #/ imports.
bun-runtime
Bun runtime patterns and best practices.

Naming - kebab-case files, front PascalCase components, singular @repo package names, unscoped apps.

typescript
Rules applied when working in TypeScript or JavaScript files.
typescript-imports
Golden rule: import each symbol from the module that defines it. A package index.ts may barrel only its own ./ modules — never another package.
