A set of Cursor rules for Blueprint Modular, a UI component library whose npm package is named @blueprint-modular/core and whose components use the bpm namespace.

Use it when changing Blueprint Modular components, especially to check repository structure, document public properties, update API references, and follow the required branch and pull-request workflow.

It gives contributors shared rules for pull requests, security, server rendering, TypeScript, documentation, file locations, and commit naming.

Per session 369 This file is loaded in full into every session.

When invoked 369 The same file — it is already loaded in full.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

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	$0.00369	$0.00369
Opus 5.5	$0.00148	$0.00148
Sonnet 5.5	$0.00074	$0.00074
Haiku 4.5	$0.00037	$0.00037

Measured 2mo ago against content hash f1318cc14bea, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

cursorrules 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 2mo 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.
