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

quark-download scanned grade A with 0 findings 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/quark_search.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Automate the full workflow: search resources → validate links → save to Quark cloud drive → download locally, by combining the PanSou aggregation API with the local Quark desktop APP.

All operations use the CLI script at ${SKILL_PATH}/scripts/quark_search.py. It outputs JSON to stdout ({"ok": true, "data": {...}} or {"ok": false, "error": "...", "code": "..."}) and logs progress to stderr.

Prerequisites Check

Before any operation, verify the environment:

python3 ${SKILL_PATH}/scripts/quark_search.py check

Response: {"ok": true, "data": {"isLogin": true, ...}} — confirms APP is running and logged in.

If the command fails with "code": "app_not_running", instruct the user to launch Quark APP. If isLogin is false, instruct the user to log in first.

A single command searches PanSou, validates all links in parallel, and fetches file details for the top results:

python3 ${SKILL_PATH}/scripts/quark_search.py search "KEYWORD" --top 5

Options:

Flag Default Description
--top N 5 Number of top valid results to return with details
--no-validate off Skip validation (faster, but may include dead links)
--limit N 30 PanSou results per page
--page N 1 PanSou page number

Success response (ok: true):

{
  "ok": true,
  "data": {
    "keyword": "三体",
    "total": 1234,
    "valid_count": 8,
    "results": [

          ]

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
