Zhihu

Browse, search, read, and interact with Zhihu — China's largest Q&A platform.

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 zhihu 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) → run sig login zhihu, then re-check.
• valid: true → detect proxy (see below), then execute the user's request.

Provider Setup

1. Read <SKILL_DIR>/references/provider-config.yaml
2. Append the provider block to ~/.sig/config.yaml under providers:
3. Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: <url> under the provider in config.yaml
4. Run sig login zhihu (with --network-proxy <url> if proxy was specified)
5. Verify: run sig status zhihu again — must show valid: true before proceeding

Proxy Detection (after provider is valid)

grep -A15 "^\s*zhihu:" ~/.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).

All operations — use sig run to inject cookie (required for all Zhihu endpoints):

sig run zhihu -- bash -c 'python3 <SKILL_DIR>/scripts/zhihu_hot.py --cookie "$SIG_ZHIHU_COOKIE" --limit 10'

Env var: SIG_ZHIHU_COOKIE

On auth error (401/403): run sig login zhihu automatically (no user prompt), then retry.

Scripts Reference

All scripts are in this skill's scripts/ directory. Run via Bash tool.

Read Operations

zhihu_hot.py

Key Concepts

Questions — The core unit on Zhihu. Each question has a title, detail, and a list of answers. Found in URLs like zhihu.com/question/12345. Get from hot list or search results, then use with zhihu_question.py.

Answers — Responses to questions, ranked by votes. Each answer has content, vote count, and author info. Use zhihu_answer.py to fetch a single answer by ID.

Hot List (知乎热榜) — Zhihu's trending questions, ranked by heat score. Use zhihu_hot.py to browse.

Topics — Zhihu organizes content into topics (like tags). Examples: AI, programming, science. Use zhihu_topic.py to search topics by keyword.

Members — User profiles identified by url_token (found in URLs like zhihu.com/people/zhang-san). Use zhihu_member.py to view profile and answers.

Search — Zhihu supports searching across questions, topics, and people. Use zhihu_search.py with the --type flag to filter.
