Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.03592 |
| Opus 5.5 | $0.00000 | $0.01437 |
| Sonnet 5.5 | $0.00000 | $0.00718 |
| Haiku 4.5 | $0.00000 | $0.00359 |
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.
How it starts
The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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 ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
