Bugcrowd Reporting Tactics
A Bugcrowd-specific reporting overlay: VRT selection, manual severity-override requests, and ready-made out-of-scope rebuttals.

What it does
- VRT selection strategy: search the dropdown in order (bug class → data exposed → control bypassed → endpoint type → generic parent) and pick the highest-severity node that still accurately describes the bug, plus a mapping table for common finding types.
- Manual severity override: when to override the VRT default and a template for the "Severity request" paragraph that goes first in the report body.
- OOS-clause rebuttals: fill-in templates for the four most common auto-closes — rate limiting on auth endpoints, "debug information", low-risk user enumeration, and "theoretical/not exploitable".
- Chained findings: filing order (primitives first, consumer second), bidirectional UUID cross-reference blocks, and "one fix = one bounty" framing.
- Researcher hygiene: bugcrowdninja email alias, post-PoC account restoration, session rotation, locked-account etiquette.
Who it's for
- Bug bounty hunters actively filing on Bugcrowd
- Researchers whose reports keep getting downgraded to P4 or closed as out of scope
- Anyone working programs that scope both production and QA assets
Examples
- A password-verify endpoint with no rate limit: keep the accurate VRT ("No Rate Limiting on Form → Login", default P4) and generate a severity-request paragraph asking for P3 standalone / P2 in chain.
- A triager closes your report citing "rate limiting on non-authentication endpoints is OOS": drop in the §4.1 rebuttal proving the endpoint is an authentication primitive.
- Password oracle + missing step-up = ATO: file both primitives first to obtain UUIDs, then file the chain consumer with a filled-in "Chain partners" block and backfill each primitive.

Paste this into Claude to use the skill without installing anything.
Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/elementalsouls/Claude-BugHunter/HEAD/skills/bugcrowd-reporting/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.
Install in the Claude app (no terminal)
- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the skills/bugcrowd-reporting folder from the GitHub repo elementalsouls/Claude-BugHunter into my ~/.claude/skills/bugcrowd-reporting/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/elementalsouls/Claude-BugHunter.git && mkdir -p ~/.claude/skills && cp -r Claude-BugHunter/skills/bugcrowd-reporting ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Clone the repo:
git clone https://github.com/elementalsouls/Claude-BugHunter.git - Create the skills directory if needed:
mkdir -p ~/.claude/skills - Copy the skill:
cp -r Claude-BugHunter/skills/bugcrowd-reporting ~/.claude/skills/ - Also copy the companion skills it expects:
report-writing,triage-validation,evidence-hygiene. - Restart Claude Code and try: "Pick the VRT and draft a severity-request paragraph for this Bugcrowd submission."
- Remember that VRT node names and default P-levels change over time — verify against what the live submission form actually suggests.
