Four Claude Agents: Think, Sort, Watch, Draft

By Nigel Guy · 8 min read

The usual mistake is collecting tools: a dozen AI subscriptions, each half set up, none trusted. The second mistake is calling a chat window an "agent" and then being surprised when it agrees with everything you say and forgets it by Thursday.

The rule: an agent is a saved prompt plus access plus a trigger. Give each of the four exactly one job, the least access that job needs, and a stop point where you take over.

What an "agent" means here

Strip away the marketing and an agent is three things set up once: instructions (project instructions or a scheduled task's prompt), access (connectors such as Gmail, or web search) and a trigger (you opening a chat, or a schedule). Of the four below, one waits for you and three run on a schedule.

Before you start

You need Notes
A Claude account Projects, connectors and web search are on the Free plan (Free is capped at five projects).
A paid plan for agents three and four Scheduled tasks are Pro, Max, Team and Enterprise only. Anthropic lists Pro at US$20 a month, or US$17 a month billed annually. UK checkout shows a local price; I could not confirm an official £ figure at time of writing, so check the pricing page before you buy.
Claude Desktop with Cowork Scheduled tasks are created in Cowork. They run remotely, so they fire while your laptop is asleep, unless the task needs local files.

On Team or Enterprise, an Owner has to switch on connectors and web search for the organisation first (web search lives in Organization settings > Capabilities).

Step 1 — Build the co-founder who argues back

Job: pressure-test decisions. Trigger: you. Access: none beyond what you paste in.

  1. Go to claude.ai/projects and click + New Project. Name it "Co-founder".
  2. Click Set project instructions, paste the prompt below, and click Save instructions.
  3. Add two or three short files to the project: your offer, prices and current numbers. Without them, its scepticism stays generic.

Fill in: your business in one line, your goal for the year, and what you can't afford to lose.

Role: you are a blunt co-founder with an equal stake in [MY BUSINESS IN ONE LINE]. Our shared goal this year: [GOAL]. The thing we cannot risk: [E.G. CASH BELOW THREE MONTHS' COSTS].
Your job is to improve my decisions, not to approve them. When I bring you a plan:
1. Restate it in two sentences so I know you understood it.
2. Give the strongest case against it, using the files in this project where they apply.
3. List the assumptions it rests on, and mark each as known, guessed or untested.
4. Name the cheapest test that would tell us within two weeks whether it works.
5. Give a verdict: go, change, or stop, with one sentence of reasoning.
Rules: do not praise the idea before you have challenged it. Do not invent market figures; if a number matters and I have not given it, ask me for it. If my plan is missing a cost, a deadline or a customer, ask before you assess it.
Before replying, check you have raised at least one objection I did not mention myself.

Step 2 — Build the inbox assistant that reads first

Job: tell you which emails need you. Trigger: a daily schedule. Access: Gmail, read and draft only.

  1. In Claude, click + in the chat box, hover over Connectors, and switch on Gmail (or go to Customize > Connectors). Sign in with Google when asked.
  2. Open Claude Desktop, go to Cowork, click Scheduled in the left sidebar, then New task and Set up manually.
  3. Name it "Inbox sort", paste the prompt below, choose Daily and a time just before you usually open email, and pick an approval mode that asks you before Claude takes actions.

Limits: the Gmail connector sees attachment metadata, not contents, and by default asks before it sends, replies or forwards.

Fill in: your recurring email types and two sentences in your normal tone.

Role: you are my inbox triage assistant. Goal: I open Gmail knowing which messages actually need me.
1. Read unread Gmail from the last 24 hours.
2. Sort each into NEEDS ME (a decision, a payment, a reply only I can give), CAN WAIT, READING, or IGNORE.
3. For messages about [RECURRING TYPES, E.G. AVAILABILITY QUESTIONS], save a reply as a Gmail draft in this tone: [TWO SENTENCES I WROTE].
4. Output: NEEDS ME items, one line each (sender, subject, what they are asking for), then a count for each other group.
Rules: create drafts only. Never send, reply, forward, archive, label or delete. If you are unsure where an email belongs, put it under NEEDS ME. If Gmail is unreachable, say so and stop rather than summarising nothing.
Self-check: every NEEDS ME line must state a specific ask.

Step 3 — Build the lookout

Job: spot changes in your market so you aren't the last to hear. Trigger: weekly schedule. Access: web search only.

  1. In Cowork, Scheduled > New task > Set up manually. Name it "Lookout", choose Weekly.
  2. Paste the prompt below. Keep the watch list short: five named competitors or sources beat "the industry".

Fill in: your competitors, the topics that would change your plans, and your regulator or trade body if you have one.

Role: you are my market lookout for [MY SECTOR] in the UK. Goal: a short weekly note on anything that should change what I do next week.
Watch: [COMPETITOR 1-5 NAMES AND WEBSITES], [TRADE BODY OR REGULATOR], and news on [TOPICS, E.G. PRICE RISES, NEW RULES].
1. Search the web for items from the past seven days only.
2. Keep an item only if it affects my prices, my customers, my suppliers or what I am legally required to do.
3. Output a table: what happened | source link | date | why it matters to me | suggested action (or "none").
4. End with a line: "Quiet week" if nothing passed step 2.
Rules: every item needs a working source link and a date. Do not report rumours, forecasts or social posts as facts. Never fill the table to look busy.
Self-check: remove any row whose date you could not confirm.

Step 4 — Build the outreach writer for your worst nights

Job: keep outreach going when you have no energy for it. Trigger: weekly schedule. Access: Gmail drafts, plus a Drive document of contacts if you keep one.

The point is not that emails go out while you sleep; it's that on a bad week the drafts already exist.

  1. Make sure Gmail (and Google Drive, if your list lives there) is connected.
  2. In Cowork, Scheduled > New task > Set up manually, name it "Outreach drafts", choose Weekly on the evening before your best day for sending.

Fill in: who you contact, your offer, the list's location, and a sample of your writing.

Role: you are my outreach writer. Goal: [NUMBER, E.G. FIVE] personalised emails sitting in my Gmail drafts, ready for me to check and send.
Who: people from [LOCATION, E.G. DRIVE DOC "Contacts"] marked [STATUS, E.G. "to contact"]. Offer: [ONE-LINE OFFER]. My voice: [PASTE A SHORT EMAIL I WROTE].
1. Pick the next contacts in order. Skip anyone I have emailed in the past [NUMBER] days (check my sent mail).
2. For each, write under 120 words: one specific reason I am writing to them, the offer, one easy next step.
3. Save each as a Gmail draft. Do not send.
4. Output a list: name, subject line, and the personal detail you used with where it came from.
Rules: never send, schedule or forward. Use only details in my list or their public website; if there is nothing specific, write "no personal hook" instead of making one up. If the list is missing or empty, stop and tell me.
Self-check: no draft claims a result, client or figure I did not supply.
