van-file-verification

A structured process for checking that required files and folders exist and are intact before implementation begins. It requires a complete memory bank, meaning the project's stored working context, first.

In plain words
What is it for?
Use it to verify the memory bank, run pattern-based file checks, report status, and stop until critical structure problems are fixed.
Why use it?
It prevents work from starting with missing project information or broken required file structure.

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-file-verification 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.

OPTIMIZED FILE VERIFICATION SYSTEM

🚨 CRITICAL: MEMORY BANK VERIFICATION REQUIRED 🚨 Memory Bank structure MUST exist before any file operations This check MUST be executed first in all verification processes

TL;DR: This system provides a structured approach to verify file structure integrity before task implementation, with emphasis on efficient checks and clear status reporting.

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.
