What problem does it solve? Before submitting a bug-bounty finding, you must verify it is not a known duplicate, but querying HackerOne Hacktivity is a human-only step. This Skill prepares everything the human needs — search terms, candidate context, and a checklist — so the novelty gate is enforced without the agent overstepping its boundary. ## Core Features & Use Cases - Search-Term Assembly: Builds a query set from the candidate's own evidence, including endpoint names, vulnerability class synonyms, error messages, and mobile deep-link identifiers. - Checklist Generation: Runs tools/duplicate_preflight_checklist.sh to enumerate findings with a null duplicate_preflight block and emit a Markdown checklist, optionally filtered by severity. - Stop-Condition Gating: Applies the negative-control taxonomy to close duplicates by root cause or below-threshold findings, keeping novelty as an explicit submission gate. - Use Case: After qualifying an IDOR candidate on a target program, run this Skill to generate the preflight checklist and search terms, hand them to a human reviewer who queries Hacktivity, and only proceed to submission once the manifest block is filled. ## Quick Start Run the duplicate preflight for my qualified candidate finding and generate the checklist and search terms for human Hacktivity review.
