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 | $0.00110 | $0.00572 |
| Opus 5 | $0.00055 | $0.00286 |
| Sonnet 5 | $0.00022 | $0.00114 |
| Haiku 4.5 | $0.00011 | $0.00057 |
Grade B, and why
competition-linux-credential-pivot scanned grade B with 1 finding 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 5d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

100% identical to competition-linux-credential-pivot — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Competition Linux Credential 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 decisive edge is Linux credential material and where that material is accepted.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Separate credential storage from accepted privilege.
- Record user, process, namespace, socket, key file, and service trust boundary before conclusions.
- Keep artifact recovery, replay path, and resulting capability in one chain.
- Distinguish local escalation from lateral host pivot.
- Reproduce one minimal artifact-to-accepted-access path.
Workflow
1. Map Credential And Trust Artifacts
- Record SSH keys, agent sockets, kubeconfigs, cloud tokens, service-account secrets, env vars, config files, and process memory clues.
- Note sudoers rules, capabilities, setuid binaries, systemd unit context, and namespace boundaries.
- Keep each artifact tied to owner, scope, and expected accepting service.
2. Prove Replay And Pivot
- Show where key, token, socket, or secret is accepted: SSH, API, Unix socket, container runtime, or control-plane endpoint.
- Record host target, protocol, principal, and resulting session or privilege.
- Distinguish authentication success from useful capability gain.
3. Reduce To Decisive Linux Pivot Chain
- Compress to: recovered artifact -> accepted replay path -> pivot host or privilege transition -> resulting capability.
- State whether root cause is weak key handling, token leakage, socket trust, sudo or capability abuse, or namespace crossover.
- If the chain pivots into kernel exploit boundaries, hand off to kernel container escape 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-linux-credential-pivot is a skill published in the GitHub repository Asaiuta/reverse-workbench-skill (2 stars, last pushed 22d ago), licensed MIT. It adds 110 tokens to every session and 572 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). It is 100% identical to competition-linux-credential-pivot, differing in 0 lines, and is treated as a copy.
