Finding Sources

Every issue includes a source badge showing where the validation rule came from. Issues from past reviews are likely to be flagged again by VVBs — prioritize these.

Verra PRR Public Verra project reviews
Varaha Internal review findings
CSI CSI/EBC C-Sink project reviews
Rating Agency Known downgrade triggers
VCS Standard Registry requirements
Methodology VM0042, VM0047, etc.

Review Pattern Data

Lens enriches analysis with patterns scraped from public registry project reviews. These patterns flag issues that real VVBs have raised in past validations/verifications.

Limitations

Not a VVB replacement. Pre-submission quality check only. Does not replicate a full validation/verification audit.
LLM hallucination risk. AI may occasionally cite incorrect rule references. Always verify critical findings.
Scanned PDFs. Documents without selectable text have degraded analysis quality. Ensure PDFs have selectable text.
Large documents. Documents over 300 pages may be truncated. Consider splitting into sections.
