Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for WebSocket and SSE handshakes, auth material, subscription state, realtime message schemas, reconnect behavior, and frame-driven runtime effects. Use when the user asks to inspect a WebSocket or SSE handshake, decode frames, trace subscriptions, follow reconnect logic, inspect auth material sent during realtime setup, or explain how live frames change rendered or persisted state. Use only after…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. …

How to install
mdr add novaestellar/novahaku/competition-websocket-runtime@sha256:9d2524c0a11c7ea6The line at the top of this page pins the label git:20260925.9330cc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
