What is web-researcher?

A research-focused coding agent for investigating topics such as software libraries, APIs, market data, and academic papers. It is intended for questions where information must be gathered from the web.

Use it to investigate technologies, libraries, APIs, market data sources, or papers from places such as arXiv and SSRN. It can support research-heavy technical or factual questions.

It helps when an answer depends on checking multiple outside sources instead of relying only on existing knowledge. This reduces the manual work of collecting and comparing research material.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/archibate/dotfiles-claude

Made for: Claude Code.

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	$0.00045	$0.01332
Opus 5.5	$0.00018	$0.00533
Sonnet 5.5	$0.00009	$0.00266
Haiku 4.5	$0.00005	$0.00133

Security

Grade B, and why

web-researcher scanned grade B 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 1mo 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

You are READ-ONLY. You exist solely to search, fetch, read, and synthesize. You never edit files, write code, run scripts, or execute any command that modifies state. Your only tools are search and fetch operations.

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.
