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

vrchat-force-purge-all-favorite-worlds scanned grade A with 1 finding 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 12d 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.

vrchat-force-purge-all-favorite-worlds

Deletes ALL favorited worlds (all groups: worlds1..worldsN) from the authenticated VRChat account. This is destructive and irreversible via the API — favorites are not recoverable after deletion.

Fixed paths used by this skill (intentionally NOT the per-session scratchpad — see Notes):

  • WORKDIR=/tmp/vrchat-force-purge-all-favorite-worlds
  • COOKIE_JAR=$WORKDIR/cookies.jar
  • FAVORITES_JSON=$WORKDIR/favorites.json
  • LOG=$WORKDIR/delete.log
  • LOCKFILE=/tmp/vrchat-force-purge-all-favorite-worlds.lock (sibling of WORKDIR, not inside it)

Behavior

  1. Credential precondition check — before anything else:

    • Verify both $VRC_USER and $VRC_PASS are set and non-empty
    • If either is missing: stop immediately. Tell the user to run export VRC_USER=... VRC_PASS=... (optionally VRC_CONTACT=..., see Notes) in their shell, then re-invoke this skill. Do not attempt login with a partial/empty credential

  2. Concurrency guard (lock):

    • mkdir -p "$WORKDIR"
    • If $LOCKFILE exists: read the PID from it, check liveness with kill -0 <PID>
      • Alive → stop, report another purge is already running (show PID + lock timestamp), refuse
      • Dead (stale) → note it, rm-dust -f "$LOCKFILE", continue
    • Do not write the lock yet — it's written atomically with the delete loop in step 8

  3. Authenticate:

    • rm-dust -f "$COOKIE_JAR" first (no stale cookies)
    • UA="vrchat-force-purge-all-favorite-worlds/1.0 (${VRC_CONTACT:-contact-not-provided})"
    • Call api.vrchat.cloud directly (never api.vrchat.com — it 307-redirects cross-host and curl drops the Authorization header on that redirect): curl -sS -u "$VRC_USER:$VRC_PASS" -A "$UA" -c "$COOKIE_JAR" -b "$COOKIE_JAR" -o "$WORKDIR/auth.json" -w '%{http_code}' https://api.vrchat.cloud/api/1/auth/user
    • Non-2xx → stop, report likely-bad credentials, no blind retry
    • If auth.json contains requiresTwoFactorAuth → step 3, else → step 4
