standard-file-size-limits-agent

standard-file-size-limits-agent is a cursor rule for Cursor from dmitryprg-ai/cursor-develop-autorules. It costs 66 tokens per session (658 once invoked), scanned A, original, no licence file.

A coding rule that sets maximum recommended and hard line counts for route, service, and component files. When a file exceeds its recommended size, it requires a splitting plan before more code is added.

In plain words
What is it for?
Use it when adding code or reviewing changes to decide whether a file should be divided. It applies different size limits to routes, services, and components.
Why use it?
It prevents large files from becoming difficult to understand, review, and change. The limits make file growth visible during coding and code review.

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

standard-file-size-limits-agent 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 6d 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.
