CTF Sandbox

Thin PRIMARY for CTF / AWD / lab multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, lab, or challenge, and no more specific pwn/APK/IDA route has already won.

What is CTF Sandbox?

This skill acts as a lightweight PRIMARY entry point for CTF, AWD, and lab challenges, delegating all orchestration to the sidecar CTF-Sandbox-Orchestrator. It is designed to prevent the core routing package from bloating with 40+ competition sub-skills, ensuring a clean separation of concerns. The skill enforces strict security boundaries: it must run `case-init.ps1` before any external network actions, and uses network profiles like `lab` or `offline` for isolation. It must not directly handle pwn, APK, or IDA challenges—those should be caught by more specific PRIMARY rules earlier in the routing table. After initializing, it immediately redirects to the orchestrator's SKILL.md for downstream task selection. Supported platforms include Capture The Flag competitions, Attack-with-Defense scenarios, and lab environments.

Documentation

CTF sandbox entry (sidecar, not a second router)

ACTION REQUIRED (execute immediately after reading)

  1. NOW: Run ../scripts/case-init.ps1; do NOT act against the real external network until auth.status=granted. For competitions/labs, use -NetworkProfile lab or offline.
  2. NOW: Open ../../CTF-Sandbox-Orchestrator/ctf-sandbox-orchestrator/SKILL.md under the package root, and continue according to its sandbox assumptions.
  3. MUST NOT include 40+ competition-* sub-skills in routing.json. This entry is just a PRIMARY latch.
  4. ACT: Let the orchestrator select a downstream competition-*. If the specific challenge type is already clear (pwn/ROP, APK, IDA), it should have been won by earlier rules in routing.json—do not override.

Why a separate layer

CTF-Sandbox-Orchestrator/ is a GPL bypass package, licensed by default inside the sandbox. The core routing package remains MIT + scope.md gates. This skill only serves as a keyword entry point; it does not merge the competition tree into the core.

Task completion self-check (MUST pass before claiming completion)

  • Did I run case-init / scope first, rather than treating "user said CTF" as granted external access?
  • Did I open the sidecar orchestrator, instead of treating 40 sub-skills as PRIMARY?
  • If the task is actually pwn/APK/IDA, did I let a more specific PRIMARY take over?
