Challenge Help

challenge-help — Pick the right skill

You are an AI assistant helping a contestant operate the Simulation Challenge platform end to end. This skill is the router: read the user's intent and direct them to the next skill, then hand off.

Routing rules

Hard rules

1. Always confirm before challenge-submit-job (each submission consumes one daily submission slot) and before launching agent processes (they hold a parallelism slot).
2. Read-only calls run without confirmation: login, current-user-info, jobs/result/log, best-score, ranking, quota check.
3. The gateway host is fixed at 120.92.88.78 and does not change. Defaults: BASE_URL=https://robocoliseum.ai (HTTP API base for all curl "$BASE_URL/api/challenge/..." calls) and TUNNEL_ENDPOINT=ws://120.92.88.78/api/challenge/tunnel (WebSocket tunnel for tunnel.sh/run-agent). The tunnel host is not the website domain — do not rewrite it to robocoliseum.ai. If the job response carries a tunnel_endpoint, prefer it; otherwise fall back to the default above — do not block on it being absent.
4. board has a closed allowed-value set today. config.board accepts exactly one of instruction / spatial / manip / robust. Any other value gets a 400 and burns quota. If the user proposes something else, stop and verify against challenge-submit-job Step 2 before POSTing. Do not invent.
5. If CHALLENGE_TOKEN is missing or returns 401, jump to challenge-login first.
6. Auto-pilot does not skip confirmation gates. If the user says "全程做完" / "do it end to end", you may merge the gates into a single up-front confirmation ("I'll submit job + launch K agents + poll until terminal — OK?"), but you may not run them silently. The 4/day quota and the GPU-holding agents are user-visible costs that must be approved.
7. 4xx is a semantic rejection, never a network blip. Do not retry a 400/401/403/404 just because the user says "可能是网络抖动" — only connection resets / 5xx / timeouts qualify as transient. Refer to challenge-troubleshoot for the exact response.
8. Job status is an integer plus a detailed_status string, and it lives on GET /api/challenge/jobs only. /job/{id}/result returns {tasks, total} with no status field. Never write a poll loop that branches on .status from /result — it never terminates. See challenge-poll-result.
9. There is no official Simulation SDK package. The supported client is the inference repo's ./scripts/tunnel.sh; contestants writing their own client use the protocol inlined in challenge-run-agent's appendix. Don't invent a pip install or point at platform-internal test clients.
10. Never quote the daily submission cap from memory. It's a platform setting, not a fixed contest constant, and it has changed. Read GET /api/challenge/submission/quota and report its limit / used / remaining verbatim. If the probe fails, say the quota is unknown rather than guessing.

Environment contract

These environment variables are the shared state between skills. Treat them as the single source of truth — never re-derive.

They are persisted to ~/.simubotix-challenge.env (mode 0600). Each Bash call should start with [ -f ~/.simubotix-challenge.env ] && . ~/.simubotix-challenge.env because AI assistants typically spawn each command in a new subshell — plain export does not survive. See README "State file" for the helper and rationale.

If a downstream skill needs a variable that isn't set after sourcing the state file, don't guess — go back to the producer skill.
