competition-agent-cloud

competition-agent-cloud is a skill for Codex from Asaiuta/reverse-workbench-skill. It costs 107 tokens per session (785 once invoked), scanned A, a copy of competition-agent-cloud, MIT.

A specialized guide for cloud and agent security challenges involving prompts, tools, deployments, containers, and software supply chains. It traces how untrusted content can move through an agent or infrastructure system toward an action.

In plain words
What is it for?
It helps analyze prompt injection, poisoned retrieval or memory, exposed mounts, deployment drift, runtime-versus-manifest differences, and build or release provenance in controlled security challenges.
Why use it?
It helps distinguish what is written in configuration from what is actually running, and focuses investigations on evidence rather than assumptions. It is intended to be used after a broader CTF sandbox workflow has established the environment.

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-agent-cloud 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.

Competition Agent Cloud

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 path is driven by prompt-to-tool execution, retrieval and memory boundaries, deployment drift, or build and release provenance.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Decide whether the dominant path is agentic or infrastructure-driven.
  2. Map one minimal control chain: untrusted input -> visible context -> tool or deployment side effect.
  3. Distinguish checked-in intent from live runtime truth.
  4. Keep prompts, tool args, manifests, mounts, and provenance steps in compact evidence blocks.
  5. Reproduce the exploit or misconfiguration with minimal context and minimal instrumentation.

Workflow

1. Agent And Prompt Injection

  • Treat prompts, tool schemas, retrieved chunks, planner notes, memory files, and handoffs as challenge artifacts.
  • Prove one minimal chain from untrusted content to model-visible instruction to tool side effect.
  • Distinguish claimed capability from runtime-exposed capability.

2. Cloud, Containers, And CI/CD

  • Split build-time, deploy-time, and runtime.
  • Reconcile compose or kube manifests with live mounts, env, logs, and traffic.
  • Trace provenance from source to dependency resolution to build to publish to runtime consumer.

Read This Reference

  • Load references/agent-cloud.md for the control-stack checklist, deployment-truth checklist, and evidence packaging.
  • If the task is specifically about prompt-boundary abuse or retrieved-content-to-tool drift, prefer $competition-prompt-injection.
  • If the task is specifically about CI, dependency provenance, registry drift, or shipped artifacts, prefer $competition-supply-chain.
  • If the task is specifically about queue payloads, async worker drift, retries, or worker-only runtime state, prefer $competition-queue-worker-drift.
  • If the task is specifically about SSRF to internal control surfaces, metadata endpoints, or metadata-derived token pivots, prefer $competition-ssrf-metadata-pivot.
  • If the task is specifically about proxy-upstream parse differentials, ambiguous headers, path normalization drift, or request smuggling behavior, prefer $competition-request-normalization-smuggling.
  • If the task is specifically about metadata-service access, instance or workload identity, link-local token paths, or metadata-derived privilege, prefer $competition-cloud-metadata-path.
  • If the task is specifically about kube API permissions, service-account trust, admission behavior, controller drift, or cluster secret exposure, prefer $competition-k8s-control-plane.
  • If the task is specifically about live mounts, sidecars, init containers, or runtime-only secret exposure, prefer $competition-container-runtime.
  • If the task is specifically about container-to-host boundary crossing, kernel-surface prerequisites, or escape primitive verification, prefer $competition-kernel-container-escape.

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.
