  2. 2.In the left sidebar, find the «Projects» section (folder icon) and click «Create project». Enter a project name - for example, «Content Plan Agent».

    If Projects isn't visible on the free plan - refresh the page or make sure you're signed in, not in guest mode.

  3. 3.In the «Custom instructions» (or «Project instructions») field, paste the system prompt that defines the agent's role, goal, and rules. Replace the text in [square brackets] with your own data.

    This is the agent's «brain» - Claude will follow these rules in every conversation within the project.

    Prompt
    You are a [role: personal content strategist]. Your goal: [main objective: plan and draft weekly social media posts for a small online store]. Rules: 1. Always respond in Russian. 2. Tone: [friendly, professional, no corporate jargon]. 3. Every post must have a hook in the first line, a value point in the middle, and a call to action at the end. 4. Keep each post under 200 words. 5. Suggest 1 relevant emoji per post - not more. 6. If the brief is unclear, ask exactly one clarifying question before writing. 7. Never invent prices, dates, or product features - ask if unsure.
    What this prompt doesThe system prompt in English sets the agent's role and rules. Replace everything in [square brackets]: role (e.g., «content strategist»), main goal, desired tone. You can leave the rest as is or adjust it to your needs.
  4. 4.In the «Project knowledge» section, upload up to 5 files (PDF, TXT, DOCX) that will become the agent's permanent knowledge base - price list, product descriptions, brand guide, examples of successful posts.

    ⚠️ Don't upload documents with customer personal data, passwords, or trade secrets - Claude processes data on Anthropic's servers.

  5. 5.Click «Create project» (or «Save»). A blank chat will open inside the project - send a test task to the agent.

    The agent will immediately apply the rules and knowledge base.

    Claude ↗About this tool
    Prompt
    Write 3 Instagram posts for next week. Products: [list 2-3 products, e.g., linen tote bag, ceramic mug, soy candle]. Promo: [e.g., free shipping on orders over 2000 RUB until Sunday].
    What this prompt doesTest prompt in English - gives the agent a specific task. Replace [products] and [promo] with your real data. You can write in any language - Claude will understand.
  6. 6.Check the response. If the tone or format isn't right - go back to project settings (gear icon next to the project name), adjust Custom instructions, and send a new task.

    Usually 2 - 3 iterations are enough for the agent to consistently produce the right result.
