050-reference-verification-system

050-reference-verification-system is a cursor rule for Cursor from savagelysubtle/BIG-BRAIN-Memory-Bank. It costs 0 tokens per session (2,128 once invoked), scanned A, original, MIT.

A set of rules for checking references to Memory Bank files, including whether the file and cited section exist and are relevant.

In plain words
What is it for?
Use it when citing Markdown or MDC memory files while working in a codebase.
Why use it?
It helps prevent answers from relying on missing, outdated, or unrelated project notes.

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

050-reference-verification-system 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 5d 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.

description: WHEN referencing memory files ENSURE references are verified for accuracy and relevance globs: ["/*.md", "/*.mdc"] alwaysApply: true

TL;DR: The Reference Verification System ensures all references to Memory Bank files are accurate, up-to-date, and relevant to the current context.

1.0.0

**In-line References**
```
According to [ActiveContext:Current Focus], the priority is...
The authentication flow described in [SystemPatterns:Auth Flow] shows...
As noted in [TechContext:Deployment], the staging environment...
```

**Block References**
```
> **Reference**: [FileName:Section]
>
> Relevant content from referenced file...
```

**Table References**
```
| Reference | Key Information | Relevance |
|-----------|----------------|-----------|
| [File1:Section] | Summary of info | How it applies |
| [File2:Section] | Summary of info | How it applies |
```

These consistent formats enable systematic verification.
1. **Existence Check**
   - Confirm referenced file exists in Memory Bank
   - Verify referenced section exists within file
   - If section doesn't exist, find closest match

2. **Recency Check**
   - Check last modification date of referenced file
   - Verify content hasn't been superseded by newer information
   - Note if reference predates significant system changes

3. **Relevance Check**
   - Verify information applies to current context
   - Confirm reference addresses current task needs
   - Assess if more specific/relevant references exist

4. **Accuracy Check**
   - Verify quoted/summarized content matches source
   - Confirm interpretation aligns with original meaning
   - Check for contextual factors that might alter meaning

5. **Extended Context**
   - Check for related information in same file
   - Identify cross-references to other relevant files
   - Note dependencies or prerequisites for understanding

Document verification status using verification indicators.
```
[✓] - Fully verified (exists, current, relevant)
[⚠️] - Partially verified (exists but with caveats)
[⏳] - Pending verification
[❌] - Verification failed (doesn't exist or invalid)
```

For partially verified references, include specific caution notes:

```
[⚠️:outdated] - Information may be outdated
[⚠️:partial] - Reference is partially relevant
[⚠️:ambiguous] - Reference could be interpreted multiple ways
[⚠️:conflict] - Conflicts with other verified information
```

These indicators ensure transparency about reference quality.

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.
