competition-websocket-runtime

competition-websocket-runtime is a skill for Claude Code, Codex from xAmirHamza77/ReverseOps-Skill. It costs 114 tokens per session (606 once invoked), scanned A, a copy of competition-websocket-runtime, MIT.

A specialist workflow for examining WebSocket and server-sent events, which are ways websites keep a live connection for ongoing messages. It focuses on connection setup, authentication, subscriptions, message formats, reconnects, and resulting state changes in a CTF sandbox.

In plain words
What is it for?
Use it to inspect live connections, trace authentication and subscriptions, decode message flows, study reconnect behavior, and reproduce the smallest sequence that causes a specific effect.
Why use it?
It helps explain behavior that cannot be understood from one ordinary web request. The workflow connects the initial handshake and later messages to visible or backend effects.

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-websocket-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 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 WebSocket 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 decisive behavior is carried by realtime handshake and frame flow rather than one-shot HTTP alone.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Map the handshake first: origin, path, headers, cookies, query, auth token, and upgrade response.
  2. Separate connection setup, subscription messages, keepalives, server pushes, and reconnect logic.
  3. Record message schema, topic or channel identity, and state side effects in one chain.
  4. Tie frames to rendered, stored, or backend-visible effects.
  5. Reproduce the smallest handshake-plus-frame sequence that reaches the decisive state change.

Workflow

1. Map The Realtime Handshake

  • Record the initial HTTP or SSE request, upgrade headers, cookies, tokens, query params, origin checks, and negotiated protocol.
  • Note whether auth material is carried by headers, cookies, query strings, or initial application frames.
  • Keep route, subscription endpoint, and session identity tied together.

2. Decode Message Flow

  • Separate subscribe, unsubscribe, ack, heartbeat, server push, reconnect, and terminal frames.
  • Recover message types, channel IDs, schema fields, and sequencing that matter to behavior.
  • Distinguish transport keepalive from application-level business messages.

3. Reduce To The Decisive Realtime Path

  • Compress the result to the smallest sequence: handshake -> auth or subscribe frame -> pushed or accepted frame -> resulting state change.
  • Keep canonical frame order and any replayed minimal order side by side.
  • If the hard part is generic protocol reassembly without runtime UI or app-state linkage, switch back to the tighter protocol 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.
