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 | $0.00102 | $0.00580 |
| Opus 5.5 | $0.00041 | $0.00232 |
| Sonnet 5.5 | $0.00020 | $0.00116 |
| Haiku 4.5 | $0.00010 | $0.00058 |
Grade A, and why
competition-kernel-container-escape 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 1mo 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.
This is a copy
100% identical to competition-kernel-container-escape — 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 Kernel Container Escape
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 step is proving a boundary crossing between containerized context and host or higher-privilege kernel context.
Reply in Simplified Chinese unless the user explicitly requests English.
Quick Start
- Map runtime isolation first: namespaces, cgroups, seccomp, capabilities, LSM, and mount boundaries.
- Separate exploit prerequisite, primitive, and boundary-crossing proof.
- Record kernel version, config hints, runtime options, and reachable syscall surface.
- Keep instrumented observations separate from pristine challenge path.
- Reproduce one minimal primitive-to-boundary-crossing chain.
Workflow
1. Map Isolation And Kernel Surface
- Record namespace map, cgroup mode, capabilities, seccomp profile, AppArmor or SELinux state, mounted filesystems, and runtime sockets.
- Note kernel version, distro build hints, module exposure, and container runtime behavior.
- Keep host and container observations linked to exact node and context.
2. Prove Exploit Primitive And Crossover
- Show controllable input, trigger condition, affected object, and observable kernel or runtime state change.
- Capture before and after identity, namespace, mount, or process visibility to prove boundary crossing.
- Distinguish crash-only behavior from stable capability gain.
3. Reduce To Decisive Escape Chain
- Compress to: prerequisite state -> primitive trigger -> boundary crossing evidence -> resulting host-level capability.
- State whether root cause is kernel vulnerability, runtime misconfiguration, capability overgrant, or namespace leak.
- If path relies mostly on credential replay after initial foothold, hand off to Linux credential 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-kernel-container-escape is a skill published in the GitHub repository 2233admin/reverse-skill-evolver (17 stars, last pushed today), licensed MIT. It adds 102 tokens to every session and 580 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to competition-kernel-container-escape, differing in 0 lines, and is treated as a copy.
