Reverse Skill is a routing package for AI coding agents that selects appropriate reverse-engineering, penetration-testing, and security-research methods and tools for a given target. It is used for tasks involving APKs, binaries, frontend JavaScript, packet captures, CTF challenges, and authorized penetration testing. Its catalogue add-ons provide the skills and instructions that guide these workflows.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00115 | $0.00732 |
| Opus 5 | $0.00057 | $0.00366 |
| Sonnet 5 | $0.00023 | $0.00146 |
| Haiku 4.5 | $0.00012 | $0.00073 |
Grade A, and why
competition-windows-pivot 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 10d 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.

Competition Windows Pivot
Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.
Use this skill when the challenge path is dominated by host-to-host movement, replayable ticket material, or Windows privilege edges.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Compress the pivot into a concrete chain: foothold -> recovered artifact -> replay path -> pivot host -> resulting capability.
- Separate stored credential material from usable privilege.
- Keep host evidence, ticket evidence, and privilege effect on one timeline.
- Record the exact accepting service or host for every replayed artifact.
- Reproduce the smallest pivot that still proves the privilege edge.
Workflow
1. Recover The Replay Material
- Inspect SAM, SECURITY, SYSTEM, NTDS, DPAPI, LSA secrets, browser stores, PowerShell history, ETW, Sysmon, and event logs in the active path.
- Distinguish password, hash, ticket, cookie, vault blob, or gMSA material by where it can actually be used.
2. Trace The Pivot Chain
- Map the protocol actually used: WinRM, SMB, RDP, WMI, admin shares, remote registry, or service control.
- When Kerberos matters, record SPN, delegation, PAC or group data, encryption type, and the accepting service.
- When AD edges matter, inspect ACLs, GPO links, SIDHistory, delegation, certificate templates, and replication rights.
3. Report The Edge
- Keep the pivot path concrete and replayable.
- State what artifact crossed which boundary and what capability appeared on the destination host.
Read This Reference
- Load
references/windows-pivot.mdfor the pivot checklist, Kerberos evidence block, and common replay mistakes. - If the task is specifically about DPAPI masterkeys, browser or vault stores, protected blobs, or proving where a recovered DPAPI secret is accepted, prefer
$competition-dpapi-credential-chain. - If the task is specifically about LSASS memory, ticket caches, replayable session material, or host-resident credential extraction, prefer
$competition-lsass-ticket-material. - If the task is specifically about delegation edges, SPN trust, S4U flow, or which service accepts the delegated ticket, prefer
$competition-kerberos-delegation. - If the hard part is forced authentication, coercion primitives, relay targets, or the service that accepts relayed auth, prefer
$competition-relay-coercion-chain.
What ships with it
2 files 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.

competition-windows-pivot is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,402 stars, last pushed 7d ago), licensed MIT. It adds 115 tokens to every session and 732 once invoked, about $0.0006 per session on Opus 5. 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 2026-08-30.
