competition-container-runtime

competition-container-runtime is a skill for Claude Code, Codex from Asaiuta/reverse-workbench-skill. It costs 109 tokens per session (684 once invoked), scanned A, a copy of competition-container-runtime, MIT.

A downstream workflow for examining what a live container or pod is actually doing. Containers package applications and their dependencies, while pods are Kubernetes units that run one or more containers.

In plain words
What is it for?
Use it to compare declared and live container state, trace how injected data reaches a process, and explain reachable runtime behavior.
Why use it?
It helps find differences between configuration files and the running system, such as mounted secrets, startup processes, sidecars, or active routes.

Token cost

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.

Security

Grade A, and why

competition-container-runtime 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 4d 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 Container Runtime

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 is really about what the live container or pod is doing now, not what the checked-in manifest claims it should do.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Split intent from reality: manifest, image, startup, live mount, live route, live process.
  2. Map host -> proxy -> container or pod -> mounted volume -> consuming process.
  3. Keep secrets, rendered config, init output, and sidecar output separate from static manifests.
  4. Prove one minimal live path from mounted or injected state to reachable behavior.
  5. Reproduce the effect with the smallest runtime-specific chain.

Workflow

1. Map The Live Runtime

  • Compare compose or kube manifests against running containers, pods, mounted volumes, env, sidecars, init containers, and entrypoints.
  • Identify which process actually consumes the mounted secret, rendered config, or shared volume output.

2. Trace Route And Mount Boundaries

  • Map virtual host, reverse proxy, service, container port, filesystem mount, and runtime-generated file paths together.
  • Record whether the decisive state is image-baked, env-injected, mounted later, or written by an init/sidecar process.

3. Report The Runtime Deviation

  • State the earliest point where live runtime diverges from checked-in intent.
  • Keep one compact evidence chain from manifest or compose intent to live consumer behavior.

Read This Reference

  • Load references/container-runtime.md for the runtime checklist, mount-chain checklist, and common live-vs-static pitfalls.
  • If the hard part is kube API permissions, service-account trust, RBAC edges, admission mutations, or controller-created workload drift, prefer $competition-k8s-control-plane.
  • If the hard part is Host-header routing, path-prefix rewriting, or route-to-service mapping across nodes, prefer $competition-runtime-routing.
  • If the hard part is proving container-to-host crossover, kernel attack-surface preconditions, or stable escape primitives, prefer $competition-kernel-container-escape.
  • If the hard part is replaying Linux secrets, socket trust edges, or host-to-host pivots after container foothold, prefer $competition-linux-credential-pivot.

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.
