systematic-attacking

systematic-attacking is a skill for Claude Code, Codex from mtarcure/claude-vibe-squad. It costs 0 tokens per session (3,592 once invoked), scanned A, original, MIT.

A controlled process for finding, verifying, combining, and reporting security vulnerabilities during authorized testing. It covers the full path from confirming scope to submitting evidence.

In plain words
What is it for?
It is for authorized bug-bounty and offensive-security work across web applications, cloud systems, smart contracts, mobile software, and other targets. It helps manage hypotheses, exploit chains, severity, proof, and duplicate findings.
Why use it?
Security testing can harm systems outside the allowed boundary, and a plausible observation is not proof of impact. This process keeps testing in scope and requires findings to be demonstrated before reporting.

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

systematic-attacking scanned grade A with 0 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 27d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Systematic Attacking

Overview

Offensive work fails in two characteristic ways: it strays outside authorized scope (the act of testing is itself potentially harmful), and it submits claims that were never really proven — reachability dressed as impact, a pile of lows dressed as a high, a known composite dressed as novel. This skill is the one method that blocks both failures.

This is the only offensive lifecycle skill. It alone owns scope, severity, lead→finding promotion, and submission authority. systematic-bug-hunting is a subordinate, zero-authority bench-craft layer nested inside Phases 2–5: it generates candidates, holds no scope or severity, and refuses to start without a Phase 0 scope lock. Experimental / novel-vector work is a phase inside it (Phase 3b), not a sibling skill — a second file would duplicate this safety lifecycle, and the looser copy would become the bypass path. systematic-debugging guards the fix; this skill guards the claim — and adds a scope law because attacking, unlike debugging, can hurt a real system.

Violating the letter of this process is violating the spirit of it. An empty gate is a skipped gate; a skipped gate is lab noise, not a finding.

When a packet contradicts this skill

Say so; do not resolve it silently. The dispatching packet still wins — that is the design. But if a packet instruction contradicts this skill, emit a ## PACKET OVERRODE SKILL section in your response naming both sides.

This is not hypothetical. H2 below states that a primitive carries capability, not severity, and that an inert primitive is labelled, never deleted. For five consecutive audits Chrono's Phase-3 packets instead demanded an impact-bar verdict per idea. Lanes obeyed the packet, killed their own primitives, and the Chaining phase starved for want of a pool — silently, because nothing made the contradiction visible.

No gate is added here. A reporting duty is enough: the failure was invisibility, not permissiveness.

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.

systematic-attacking is a skill published in the GitHub repository mtarcure/claude-vibe-squad (165 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,592 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-19.
