    "name": "dupcheck",
    "description": "Check if a vulnerability has already been reported. Searches platform hacktivity + local findings. Usage: \/dupcheck <vuln_type> e.g. \/dupcheck XSS in search endpoint"
}

Check for duplicate reports: $ARGUMENTS

Determine the platform and program from scope.yaml in the current directory.
Use bounty-platforms MCP tool search_hacktivity with platform, program, and "$ARGUMENTS" as the query.
Also search local findings: uv run python3 ../../tools/dedup_findings.py --stats --db findings.json
Read hacktivity.md if it exists and grep for related terms.
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.
