What is netreach CLAUDE.md?

Project instructions for NetReach, a Python command-line tool and library that installs and diagnoses read-only access to several public internet sources without requiring user logins. It routes agents to upstream search tools rather than acting as an API wrapper.

Use them to install dependencies, configure the tool, run diagnostics, execute tests, and maintain the routing for sources such as websites, YouTube, RSS, GitHub, V2EX, Bilibili, and web search.

They clarify the project’s no-login scope, supported source channels, configuration approach, and commands for checking whether an installation works.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00655	$0.00655
Opus 5.5	$0.00262	$0.00262
Sonnet 5.5	$0.00131	$0.00131
Haiku 4.5	$0.00065	$0.00065

Security

Grade A, and why

netreach 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 2mo 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

NetReach (no-login fork) — Python CLI + library that gives AI agents read/search access to 7 no-login, low-risk internet sources. Positioning: installer + doctor + config tool. NOT a wrapper — after install, agents call upstream tools directly. This fork removes all login/Cookie channels (Twitter, Reddit, Facebook, Instagram, XiaoHongShu, LinkedIn, Xueqiu, Xiaoyuzhou). License: MIT | Version: 2.0.0

Commands

pip install -e . — Dev install
pytest tests/ -v — All tests
pytest tests/test_cli.py -v — CLI tests only
python -m agent_reach.cli doctor — Run diagnostics
python -m agent_reach.cli install --env=auto — Auto-configure

Structure

agent_reach/cli.py — CLI entry point (argparse; install / doctor / version)
agent_reach/core.py — Core read/search routing logic
agent_reach/config.py — Config management (YAML, env vars; proxy only)
agent_reach/doctor.py — Diagnostics engine
agent_reach/probe.py — Upstream command probing (missing / broken / timeout / ok)
agent_reach/channels/ — One file per platform (web.py, youtube.py, rss.py, github.py, v2ex.py, bilibili.py, exa_search.py)
agent_reach/channels/base.py — Base channel class
agent_reach/channels/mcporter.py — Read-only mcporter config helpers
agent_reach/skill/ — SKILL.md + references/ (search / web / dev / video)
agent_reach/utils/ — paths / process / text / url helpers
tests/ — pytest tests

Conventions

Python 3.10+ with type hints
Each channel is a single file in channels/, inherits from Channel
Channel contract: implement can_handle(url) and check(config); backends is an ordered candidate list
check() must really probe backends (via probe_command) and set self.active_backend
Use loguru for logging, rich for CLI output
Commit format: type(scope): message (one commit = one thing)
All upstream tool calls go through public API/CLI, never hack internals

Rules

NEVER modify upstream open source projects' source code
NetReach is a "glue layer" — only route and call, don't reimagine
No login/Cookie channels in this fork — never re-add credential-based platforms
Version in THREE places must match: pyproject.toml, __init__.py, tests/test_cli.py
Always new branch for changes, PR to main, never push to main directly
Run pytest tests/ -v before committing — all tests must pass

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.
