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 | $0.00123 | $0.00737 |
| Opus 5 | $0.00062 | $0.00368 |
| Sonnet 5 | $0.00025 | $0.00147 |
| Haiku 4.5 | $0.00012 | $0.00074 |
Grade A, and why
competition-lsass-ticket-material 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 12d 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 LSASS Ticket Material
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 decisive host artifact lives in LSASS, ticket caches, or adjacent credential material and the hard part is proving what is replayable.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Separate raw credential material from actually usable replay edges.
- Record logon session, LUID, ticket cache, package, account, and target service before broad conclusions.
- Keep host artifact, extracted secret, replay attempt, and resulting acceptance in one chain.
- Distinguish password, hash, ticket, DPAPI secret, SSP residue, and token by where each can actually be used.
- Reproduce the smallest host-artifact-to-accepted-privilege path that proves the decisive edge.
Workflow
1. Map LSASS And Adjacent Credential State
- Record logon sessions, LUIDs, ticket caches, package names, SSPs, DPAPI context, and any service-account material tied to the active path.
- Note whether the decisive value is a TGT, service ticket, delegated ticket, DPAPI secret, plaintext, hash, or package-specific secret.
- Keep host source, account context, and cache location tied together.
2. Prove Replay Or Acceptance
- Show where the extracted material is accepted: SMB, WinRM, service ticket use, DPAPI unwrap, Schannel, or another host or service edge.
- Record SPN, target host, logon session, ticket flags, encryption type, and resulting privilege or token change.
- Distinguish material that is present from material that is actually replayable in this path.
3. Reduce To The Decisive Credential Chain
- Compress the result to the smallest sequence: host artifact -> extracted material -> accepted replay or unwrap -> resulting capability.
- State clearly whether the decisive edge lives in LSASS memory, ticket cache reuse, DPAPI context, or accepting service behavior.
- If the task broadens into full host-to-host pivoting, hand back to the tighter Windows pivot skill.
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-lsass-ticket-material is a skill published in the GitHub repository zhaoxuya520/reverse-skill (35,402 stars, last pushed 8d ago), licensed MIT. It adds 123 tokens to every session and 737 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.
