web-researcher

web-researcher is an agent for coding agents from NanoBoom/nano-claude-code-plugins. It costs 63 tokens per session (1,042 once invoked), scanned A, original, no licence file.

A web research assistant that searches for information outside its built-in knowledge, such as current documentation, recent APIs, and development practices, then summarises the findings with citations.

In plain words
What is it for?
It is for researching technical questions, checking current software documentation, and collecting sourced findings from the web.
Why use it?
It helps when information may have changed or is too new to rely on older training data.

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.

Security

Grade A, and why

web-researcher 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 4d 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 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.
