A command-line tool that lets an AI coding agent search and read web pages and content from services such as GitHub, Reddit, YouTube, LinkedIn, and Twitter/X. It also includes a diagnostic command to check which sources are available.

Use it to search the web, read URLs, inspect social posts and threads, retrieve YouTube subtitles, and query supported platforms.

It removes the need to switch between separate browsing tools for different websites. The diagnostic check shows which connections currently work.

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	$0.00318	$0.01559
Opus 5	$0.00159	$0.00779
Sonnet 5	$0.00064	$0.00312
Haiku 4.5	$0.00032	$0.00156

Security

Grade A, and why

agent-reach scanned grade A with 1 finding 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 11d 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.

What ships with it

3 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.

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.
