browser-fetcher

browser-fetcher is an agent for coding agents from kikakkz/wait-agent. It costs 0 tokens per session (90 once invoked), scanned A, original, no licence file.

A browser-fetching agent that retrieves web content, produces output, and validates what it fetched.

In plain words
What is it for?
Use it when an agent needs to fetch a web page and validate the returned content.
Why use it?
It helps obtain checked web content without treating every fetch result as automatically correct.

Agent

Part of the rust-skills plugin — 24 skills, 21 commands, 11 agents, 1 hook, 1 MCP server shipped together

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.

agentmods
npx agentmods add agents/kikakkz/wait-agent/browser-fetcher
Clone the repo
git clone --depth 1 https://github.com/kikakkz/wait-agent

Or install rust-skills, the plugin that ships this one along with the rest of its 24 skills, 21 commands, 11 agents, 1 hook, 1 MCP server.

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

browser-fetcher 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 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.

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.

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.

browser-fetcher is an agent published in the GitHub repository kikakkz/wait-agent (23 stars, last pushed today), with no licence file. It costs nothing until one of its globs matches a file; then it loads 90 tokens. 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.
