competition-runtime-routing

competition-runtime-routing is a skill for Codex from xAmirHamza77/ReverseOps-Skill. It costs 120 tokens per session (682 once invoked), scanned A, a copy of competition-runtime-routing, MIT.

A workflow for determining which proxy rule, host, container, or process serves a network request. It maps the path from the client through routing layers to the service and any downstream store or worker.

In plain words
What is it for?
Use it to trace reverse-proxy and virtual-host routing, forwarded headers, path rewrites, WebSocket upgrades, base URLs, and multi-node service selection in a CTF sandbox.
Why use it?
It explains why the same-looking request can reach different services when its host, forwarded headers, path prefix, scheme, or WebSocket settings change. Testing one input at a time makes the route decision verifiable.

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-runtime-routing 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 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.

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 Runtime Routing

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 question is which sandbox node, proxy rule, or header-derived branch actually serves the live request.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Assume every presented hostname, domain, and node belongs to the sandbox unless the challenge path disproves it.
  2. Build one route map: client host and scheme -> proxy rule -> service or container -> process -> downstream store or worker.
  3. Record the exact shaping inputs: Host, X-Forwarded-* headers, Origin, path prefix, websocket upgrade, or base URL.
  4. Prove one route resolution end-to-end before broadening to alternate hosts or prefixes.
  5. Re-run the same request with one routing input changed at a time.

Workflow

1. Map Route Inputs

  • Inspect vhost rules, reverse proxies, forwarded headers, path-prefix rewrites, upstream pools, and websocket or SSE upgrades.
  • Note which parts of the request influence routing or app behavior: host, scheme, port, path, prefix, cookie scope, or origin.
  • Treat public-looking domains, cloud hostnames, and separate VPS nodes as sandbox routing fixtures first.

2. Trace Route To Live Consumer

  • Map hostname to proxy rule to container or process to port to downstream service.
  • Compare checked-in proxy intent against live listeners, mounted configs, runtime env, and observed traffic.
  • Keep headers, proxy config, and live request traces tied together in one evidence chain.

3. Prove The Decisive Deviation

  • Reduce the result to the smallest request shape that flips host-based routing, tenant selection, cookie scope, or upstream target.
  • Distinguish route resolution from application auth logic; prove where each decision really happens.
  • If the problem shifts from routing to general web state or container runtime drift, switch back to the broader parent skill.

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.
