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 | $0.00110 | $0.00841 |
| Opus 5 | $0.00055 | $0.00420 |
| Sonnet 5 | $0.00022 | $0.00168 |
| Haiku 4.5 | $0.00011 | $0.00084 |
Grade A, and why
competition-identity-windows 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 13d 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 Identity Windows
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 revolves around identity flow, replayable credentials, Windows host artifacts, enterprise mail, or lateral movement.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Map the identity or pivot chain before diving into every host artifact.
- Separate credential possession from accepted privilege.
- Correlate identity evidence, host evidence, and mail evidence on one timeline.
- Keep tickets, SIDs, event IDs, mailbox rules, and pivot hosts in compact evidence blocks.
- Reproduce the privilege edge or mail effect from the smallest viable chain.
Workflow
1. Identity And AD
- Trace principal origin, sync path, token or ticket minting, claims transformation, group resolution, and accepting service.
- When Kerberos matters, record ticket type, SPN, delegation mode, PAC or group data, encryption type, and cache location.
2. Windows Host And Pivoting
- Correlate SAM, SECURITY, SYSTEM, NTDS, DPAPI, LSA secrets, ETW, Sysmon, PowerShell, services, tasks, WMI, WinRM, SMB, and RDP as one pivot graph.
- Express movement as a concrete chain: foothold -> recovered artifact -> replay path -> pivot host -> resulting capability.
3. Enterprise Messaging
- Keep phishing lures, consent logs, mailbox rules, and identity-provider events tied together so the mail path and privilege path stay connected.
Read This Reference
- Load
references/identity-windows.mdfor the ticket, host, and enterprise-messaging checklist. - If the task is primarily a host-to-host pivot, Kerberos replay, or Windows privilege chain, prefer
$competition-windows-pivot. - If the task is specifically about constrained delegation, unconstrained delegation, RBCD, S4U, or ticket-acceptance proof, prefer
$competition-kerberos-delegation. - If the task is specifically about AD CS, certificate templates, EKUs, enrollment rights, PKINIT, or cert-based privilege, prefer
$competition-ad-certificate-abuse. - If the task is specifically about OAuth or OIDC claims, callback flow, scopes, consent, or accepted login identity, prefer
$competition-oauth-oidc-chain. - If the task is specifically about DPAPI masterkeys, vault blobs, browser or vault secrets, backup-key use, or protected-secret-to-access chains, prefer
$competition-dpapi-credential-chain. - If the task is specifically about LSASS memory, ticket caches, LUID-linked material, DPAPI context, or replayable host credential artifacts, prefer
$competition-lsass-ticket-material. - If the task is specifically about mailbox rules, forwarding, OAuth consent, delegate access, or transport-level mail abuse, prefer
$competition-mailbox-abuse. - If the task is specifically about forced authentication, relay targets, or proving which service 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-identity-windows is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,595 stars, last pushed 9d ago), licensed MIT. It adds 110 tokens to every session and 841 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.
