300_no_function_imports

300_no_function_imports is a cursor rule for Cursor from irskep/persistproc. It costs 123 tokens per session, scanned A, original, MIT.

A project rule that requires all module imports to appear at the top level of a file, outside functions and methods.

In plain words
What is it for?
Use it when reviewing or writing Python code to enforce the project's import layout.
Why use it?
It keeps dependencies visible in one place and avoids imports being repeated during function calls.

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.

Security

Grade A, and why

300_no_function_imports 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 4d 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 it actually says

Rule: No imports inside functions

FORBIDDEN: Importing modules inside a function or method body. All imports must be declared at the module's top level.

RATIONALE: Keeping imports at the top makes dependencies explicit, avoids repeated import overhead, and aligns with project style guidelines.

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.
