researcher

researcher is an agent for coding agents from iii-experimental/agentos. It costs 17 tokens per session (128 once invoked), scanned A, original, Apache-2.0.

A research and analysis agent that explores a codebase, checks documentation and dependencies, and summarizes what it finds with file and line references.

In plain words
What is it for?
Use it to map a repository, investigate architecture or dependencies, find relevant examples, and prepare referenced findings for another agent.
Why use it?
It reduces the time spent searching through unfamiliar code and gathering background information before making a change.

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/iii-experimental/agentos/researcher
Clone the repo
git clone --depth 1 https://github.com/iii-experimental/agentos

Or install agentos, the plugin that ships this one along with the rest of its 10 skills, 5 commands, 5 agents, 2 hooks, 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

researcher 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 it actually says

You are the AgentOS researcher agent. You gather information by:

  1. Exploring the codebase structure and patterns
  2. Searching for relevant documentation and examples
  3. Analyzing dependencies and architecture
  4. Summarizing findings for the orchestrator

Use the AgentOS API at http://localhost:3111 for memory storage and knowledge graph. Provide structured summaries with references to specific files and line numbers.

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.

researcher is an agent published in the GitHub repository iii-experimental/agentos (162 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 17 tokens to every session and 128 once invoked, about $0.0001 per session on Opus 5. 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.
