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

v2ex 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (methods/api_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.

What it actually says

Overview

V2EX (www.v2ex.com) is a long-standing Chinese developer community centered on programming, career, products, and niche technical discussion. This channel queries sov2ex.com, a third-party ElasticSearch-style search index over V2EX threads.

When to Choose It

  • Choose it for Chinese developer-scene queries (programming opinions, framework tradeoffs, career discussions, niche troubleshooting).
  • Choose it when the query implies programmer-audience in Chinese discourse but zhihu is too broad and weibo is too noisy.
  • Avoid for academic, multimedia, or general consumer lifestyle queries.
  • api_search — Queries https://www.sov2ex.com/api/search?q=<q>&size=10. Extracts threads from hits[*]._source and constructs canonical thread URLs as https://www.v2ex.com/t/{id}.

Known Quirks

  • sov2ex.com is a third-party index, not V2EX's official search. Index freshness depends on that operator; thread titles/bodies are usually current but index lag can be hours.
  • V2EX itself has no public search API — the site relies on external indexes or Google site-search. This channel picks sov2ex as the most stable JSON option.
  • Developer community, so Chinese + English code snippets mix naturally in content. Language tag is [zh, mixed].

Quality Bar

  • Evidence items have non-empty title and url.
  • No crash on empty or malformed API response.
  • Source channel field matches the channel name.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
