van-complexity-determination

van-complexity-determination is a cursor rule for Cursor from alkoleft/mcp-bsl-platform-context. It costs 0 tokens per session (1,276 once invoked), scanned A, a copy of van-complexity-determination, MIT.

A decision guide for VAN mode, a workflow phase that assesses a coding task before work begins. It assigns the task one of four complexity levels based on its scope and architectural impact.

In plain words
What is it for?
It helps classify bug fixes, enhancements, multi-component features, and system-wide architectural changes.
Why use it?
It helps avoid treating a small bug fix like a large system change, or overlooking the planning needed for work that affects several parts of a project.

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

van-complexity-determination 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 3d 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.

VAN MODE: COMPLEXITY DETERMINATION

TL;DR: This component determines the appropriate complexity level (1-4) for the current task and directs the workflow accordingly.

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.
