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 5.1 | $0.01864 | $0.01864 |
| Opus 5 | $0.00932 | $0.00932 |
| Sonnet 5 | $0.00373 | $0.00373 |
| Haiku 4.5 | $0.00186 | $0.00186 |
Grade A, and why
crawl4weibo CLAUDE.md 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 7d 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.

Project Overview
Crawl4Weibo is a production-ready Python library for scraping Weibo (微博) mobile web data. It handles anti-scraping mechanisms (including "432 protection"), manages proxy pools, and returns structured data models. Browser-based cookie acquisition using Playwright is the default approach for bypassing anti-scraping.
Development Commands
Setup and Installation
uv sync --dev # Install all dependencies (including Playwright)
uv run playwright install chromium # Install Chromium browser
Testing
uv run pytest # Run all tests
uv run pytest -m "unit and not slow" # Fast tests only (pre-PR gate)
uv run pytest tests/test_proxy.py -v # Specific test file
uv run pytest tests/test_proxy.py::TestProxyPool::test_batch_proxy_fetch_multiple_proxies # Single test
Test markers: @pytest.mark.unit, @pytest.mark.integration, @pytest.mark.slow
Code Quality
uv run ruff check crawl4weibo --fix # Lint and auto-fix
uv run ruff format crawl4weibo # Format code
Examples
uv run python examples/simple_example.py # Basic usage
uv run python examples/download_images_example.py # Image download demo

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.

crawl4weibo CLAUDE.md is an instructions file published in the GitHub repository Praeviso/crawl4weibo (44 stars, last pushed 7d ago), licensed MIT. It adds 1,864 tokens to every session, about $0.0093 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.
