Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00180 | $0.02742 |
| Opus 5 | $0.00090 | $0.01371 |
| Sonnet 5 | $0.00036 | $0.00548 |
| Haiku 4.5 | $0.00018 | $0.00274 |
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 2d 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.
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 — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.
V2EX
Browse, search, read, and interact with V2EX — the creative workers' community.
Skill Directory
<SKILL_DIR> is the directory containing this SKILL.md file. Determine it ONCE at the start and reuse it.
Setup (run FIRST — every time, before any operation)
You MUST complete this setup before running any script. Do NOT skip this step.
sig status v2ex 2>&1
Check the JSON output fields configured and valid:
configured: false→ run Provider Setup below. Do NOT proceed without completing it.valid: false(but configured: true) → runsig login v2ex, then re-check.valid: true→ detect proxy (see below), then execute the user's request.
Provider Setup
- Read
<SKILL_DIR>/references/provider-config.yaml - Append the provider block to
~/.sig/config.yamlunderproviders: - Ask the user: "Do you need a proxy to access this site?" — if yes, add
networkProxy: <url>under the provider in config.yaml - Run
sig login v2ex(with--network-proxy <url>if proxy was specified) - Verify: run
sig status v2exagain — must showvalid: truebefore proceeding
Proxy Detection (after provider is valid)
grep -A15 "^\s*v2ex:" ~/.sig/config.yaml | grep networkProxy | awk '{print $2}'
If this outputs a URL, prefix ALL python3 commands with HTTPS_PROXY=<url> HTTP_PROXY=<url>.
If using socks5, convert to socks5h for python (e.g. socks5://... → socks5h://...).
If empty, no proxy needed.
Running Scripts
All scripts require setup to be completed first (see above).
Read operations — use sig run to inject cookie (enables authenticated features):
sig run v2ex -- bash -c 'python3 <SKILL_DIR>/scripts/v2ex_hot.py --cookie "$SIG_V2EX_COOKIE"'
Write operations — require sig run (cookie is mandatory):
sig run v2ex -- bash -c 'python3 <SKILL_DIR>/scripts/v2ex_reply.py --cookie "$SIG_V2EX_COOKIE" --topic-id 12345 --content "Nice post!"'
Env var: SIG_V2EX_COOKIE
What ships with it
31 files 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.

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.
- 2d ago First seen · 279 lines · 180 tokens per session scan A 1b11f9581911
v2ex is a skill published in the GitHub repository sigcli/sigcli (286 stars, last pushed 8d ago), licensed MIT. It adds 180 tokens to every session and 2,742 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
