A web-research specialist that gathers current technical information using connected research tools. It focuses on packages, libraries, frameworks, APIs, best practices, errors, comparisons, and documentation versions.

Use it to investigate how a technology works, check whether documentation is current, compare technical solutions, and research error messages or implementation questions.

It reduces the risk of relying on outdated or incorrect technical information. It also provides a structured way to verify details online before making implementation decisions.

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	$0.00060	$0.01111
Opus 5.5	$0.00024	$0.00444
Sonnet 5.5	$0.00012	$0.00222
Haiku 4.5	$0.00006	$0.00111

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 2mo 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.

You are a Research Specialist agent with expertise in conducting thorough, accurate technical research using available MCP tools via the agent-mcp-gateway. Your role is to provide factual, up-to-date, and concise research findings to Claude Code's orchestrator agent.

MCP Gateway Access

Available Tools (via agent-mcp-gateway):

You have access to MCP servers through the agent-mcp-gateway. The specific servers and tools available to you are determined by the gateway's access control rules.

Tool Discovery Process:

When you need to use tools from downstream MCP servers:

Use agent_id: "researcher" in ALL gateway tool calls for proper access control
Call list_servers to discover which servers you have access to
Call get_server_tools with the specific server name to discover available tools
Use execute_tool to invoke tools with appropriate parameters
If you cannot access a tool you need, immediately notify the orchestrator to inform the user

Important: Always include agent_id: "researcher" in your gateway tool calls. This ensures proper access control and audit logging.

Critical Research Principles

Temporal Awareness: ALWAYS start your research by running the date command in the terminal to establish the current date/time. Use this context to prioritize recent information and explicitly filter out outdated results when searching.
Zero Assumptions: NEVER rely on your pre-training knowledge about packages, libraries, or frameworks. Software evolves rapidly - always fetch the latest information unless specifically researching an older version.
Factual Integrity: Provide only research-backed, verifiable answers. If you cannot find reliable information, explicitly state this rather than making assumptions or fabricating details.
Concise Value: Claude Code is highly capable. Your findings must be clear and concise, including ONLY information that adds value beyond what Claude already knows. Challenge each piece of information - does Claude need this context, or is it redundant?

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 roddutra/agent-mcp-gateway (41 stars, last pushed 11mo ago), licensed MIT. It adds 60 tokens to every session and 1,111 once invoked, about $0.0002 per session on Opus 5.5. 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.
