name: researcher
description: Reads background material and
  produces short, source-cited summaries. Use
  for any task that means reading many files
  and reporting back.
tools: Read, Grep, Glob

You are a research specialist.
1. Read every relevant file. Be thorough.
2. Summary of one page or less.
3. Cite the source file for every claim.
4. End with a "Gaps" line for anything
   you could not determine.
Your reply is your entire report.
the coordinator's briefing to the researcher
Task for researcher:

Question: what has been decided about the
intake redesign?

Where to look: everything in the research
folder (42 meeting summaries, May to July).

Report format: one page or less. A source
citation for every claim. End with a Gaps
line for anything you cannot determine.

INTAKE DECISIONS (from 42 files)

· Single front door approved
  (research/2026-05-02-steerco.md)
· Tiering model: 3 tiers, risk based
  (research/2026-06-11-workshop.md)
· Intake form owner: governance office

file provided.
the coordinator, asked about a detail not in the report
You: what did the workshop group say about
     the intake form's length?

Claude: The researcher's report doesn't
cover that. It focused on decisions made,
and form length wasn't one of them. Want me
to send the researcher back with that
specific question?

name: reviewer
description: Checks a draft against its source
  reports. Use before anything is marked final.
tools: Read
---

You are a hostile reviewer. Given a draft
and its sources:
1. Flag every claim with no supporting
   citation.
2. Flag every contradiction between
   sources, citing both files.
3. Never compliment. Problems only.
the reviewer's findings
Problems found:

1. UNSUPPORTED: the draft says "approved
   unanimously." No source states this.

2. CONTRADICTION: 2026-05-02-steerco.md
   approves a single front door, but
   2026-07-09-steerco.md reopens the
   question. The draft only cites May.

Recommend: soften claim 1, footnote the
July reversal on claim 2.
the arrangement, named
MULTI-AGENT ORCHESTRATION

what you watched:  hub and spoke
  one coordinator in the middle,
  specialist agents around it,
  briefings out, reports back

two common variations:

  fan out:   many specialists at once,
             each on an independent slice

  pipeline:  one worker's report becomes
             the next worker's input
             (research → draft → review)
Module 04 · Walkthrough
One coordinator, two specialists
What "building an agent" actually means, watched live. Three parts:
1 · What an agent is 2 · The delegation 3 · The attack
A separate brain for every heavy job
One clean window holds the goal. Specialist windows hold the heavy reading and get thrown away when the report crosses back. The closing demo builds this exact pair, prompt by prompt.
