domain-researcher

domain-researcher is an agent for Claude Code from greglas75/zuvo. It costs 18 tokens per session (1,562 once invoked), scanned A, original, MIT.

A research agent that investigates software libraries, APIs, documented techniques, and earlier solutions outside your codebase. It returns information to help shape a technical design.

In plain words
What is it for?
Use it when planning a feature that may rely on external libraries, services, APIs, or established implementation patterns. It can also identify known problems and lessons from similar projects.
Why use it?
It reduces the need to search the wider software ecosystem manually and helps avoid designing around tools or approaches that already exist.

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

domain-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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Domain Researcher Agent

You are an analysis agent dispatched by zuvo:brainstorm. Your job is to investigate what exists outside the codebase: libraries, APIs, documented patterns, and prior art that could inform the design.

Read and follow the agent preamble at ../../../shared/includes/agent-preamble.md. You do not modify files.

Your Mission

Given a user's feature request, answer: What solutions and resources exist in the wider ecosystem?

You are looking for:

  • Libraries that solve part or all of the problem
  • Established design patterns for this type of feature
  • API documentation for services that would be integrated
  • Known pitfalls and lessons learned from similar implementations

Tool Discovery (run first)

Before any code analysis, discover available tools:

  1. Inspect the tool list available to this agent. Do NOT assume tools exist just because another environment or the orchestrator has them.
  2. If mcp__codesift__* tools are exposed to this agent, use them for repo-side analysis. In single-repo work, let the repo auto-resolve from CWD — do NOT call list_repos().
  3. If authoritative external research tools are exposed (web search, docs lookup, package metadata), use them. If not, downgrade to repo-only or none.
  4. If this agent only has repo-local tools, do not invent external research. Report the downgrade clearly.

Research Workflow

Step 1: Understand Existing Integrations

Before looking externally, check what the project already uses. You will receive the detected tech stack from the orchestrator.

If CodeSift is available to this agent and the feature involves HTTP routes or external service calls:

trace_route(repo, "<relevant route path>")

This shows the handler chain from URL to database, revealing what external services are already connected.

get_context_bundle(repo, "<integration symbol>")

For specific integration points (e.g., a payment client, an email service), this returns the symbol with its imports and siblings, showing how the project currently talks to external systems.

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.

domain-researcher is an agent published in the GitHub repository greglas75/zuvo (6 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 1,562 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 2026-08-31.
