dupcheck

Check for duplicate reports: $ARGUMENTS

1. Determine the platform and program from scope.yaml in the current directory.
2. Use bounty-platforms MCP tool search_hacktivity with platform, program, and "$ARGUMENTS" as the query.
3. Also search local findings: uv run python3 $CLAUDE_PROJECT_DIR/tools/dedup_findings.py --stats --db findings.json
4. Read hacktivity.md if it exists and grep for related terms.
5. Report:
   • Exact or near matches from hacktivity (potential duplicates)
   • Related reports that might overlap
   • If the area appears heavily reported (high duplicate risk)
   • Verdict: likely unique, possible duplicate, or high duplicate risk

Writeup Cross-Reference (if writeup-search MCP is available)

After checking local findings, also search the writeup database:

• Use search_writeups MCP tool with " "
• If similar writeups exist, assess whether your finding is novel or a known pattern
• Mention relevant prior art in the "Known Techniques" section of the report

Top-Tier Duplicate Analysis

Duplicate risk is about overlap of exploit primitive and affected asset, not keyword similarity.

Report four verdict fields:

• same_asset_same_primitive: likely duplicate unless your impact is strictly stronger
• same_primitive_different_asset: possible duplicate; explain scope difference and novelty
• same_asset_different_primitive: usually unique; prove a different root cause
• known_class_new_chain: often worth reporting if the chain reaches a new impact tier

Check disclosed writeups for patch language and response tone. If triagers historically close this class as N/A, require chain proof before submission. If public reports stop at a weaker impact, frame your report around the new capability, not the shared first step.
