Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for browser cookies, localStorage, sessionStorage, IndexedDB, Cache Storage, service workers, offline caches, and client-side session persistence. Use when the user asks to inspect browser state, replay cached auth or session behavior, explain why a page behaves differently after load, or trace how stored client state changes requests, rendering, or access. Use only after `$ctf-sandbox-orchestrator` has already…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Competition Browser Persistence Use this skill only as a downstream specialization after `$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 branch lives in browser-held state rather than only in visible HTML or backend source. Reply in Simplified Chinese unless the user explicitly requests English. ## Quick Start 1. Identify the active persistence surface first: cookie jar, localStorage, sessionStorage, IndexedDB, Cache Storage, or service worker. 2. Record origin, scope, domain, path, expiry, and key names before mutating state. 3. Tie stored state to one concrete effect: request header, rendered branch, cached response, offline behavior, or hidden route access. 4. Separate boot-time state from runtime-mutated state. 5. Reproduce the smallest stateful sequence that reaches the decisive branch. ## Workflow ### 1. Map Browser State Surfaces - Inspect cookies, storage buckets, service worker registrations, cache entries, and transient globals exposed during boot. …

How to install
mdr add novaestellar/novahaku/competition-browser-persistence@sha256:b538f26b35be0189The line at the top of this page pins the label git:20260928.e15e43c, 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.
