Repository instructions for a multi-agent project that searches open-source software for security vulnerabilities and prepares responsible disclosures.

In plain words
What is it for?
Use them when coordinating reconnaissance, code review, local proof-of-concept testing, validation, and CVE reporting.
Why use it?
They define the research roles, review process, communication rules, and limits on testing so findings are handled safely.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is ByamB4/find-cve-agent's own configuration. It tells Claude Code how to work on find-cve-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything find-cve-agent configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

find-cve-agent CLAUDE.md scanned grade A with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CLAUDE.md -- find-cve-agent

A Claude Code plugin for systematic CVE hunting in open source packages. All agents auto-load this file. Read your role section before starting work.


Project Overview

This plugin provides a structured, multi-agent workflow for finding real CVEs in open source projects through responsible disclosure.

  • Primary goal: Find genuine security vulnerabilities and get CVE assignments
  • Secondary goal: Bug bounty rewards (when programs exist)
  • All work follows responsible disclosure (90-day coordinated timeline)
  • No exploitation of production systems -- PoCs run locally only
  • Quality over quantity -- one confirmed CVE beats ten false positives

Agent Team Architecture

This workspace runs as a 5-role agent team plus a human Director.

DIRECTOR (you, the human)
     |
     +-- RECON      - finds GitHub targets, proposes to Director
     +-- REGISTRY   - tracks everything, prevents duplicates
     +-- HUNTER     - deep code review, finds vulnerabilities
     +-- EXPLOITER  - builds PoCs, chains findings (plan approval required)
     +-- VALIDATOR  - tests in real environment, kills false positives

Communication Rules

  • Recon -> Director: "Propose target: [project]. Reason: [X]. Approve?"
  • Recon -> Registry: "Mark [project] as IN_PROGRESS"
  • Hunter -> Exploiter: direct message with finding details
  • Hunter -> Registry: "Mark as SKIP" if nothing found
  • Exploiter -> Director: "Approve PoC plan: [finding]. Plan: [Y]. Impact: [Z]."
  • Validator -> Director: final verdict (CONFIRMED / FALSE_POSITIVE)
  • Validator -> Registry: record every outcome without exception
  • Registry answers any agent: "Has [X] been investigated?"

Ethical Guardrails

  1. Responsible disclosure only. 90-day coordinated timeline from first contact.
  2. No production exploitation. All PoCs run against local instances only.
  3. No destructive payloads. PoCs demonstrate the vulnerability without causing harm.
  4. Report to maintainers first. Public disclosure only after the timeline expires.
  5. Credit the maintainer's response. Acknowledge good-faith patch efforts.
  6. No mass scanning. Targets are selected individually and reviewed manually.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
