Influencer Brief Generator with Claude: A 1-Page Brief in 10 Minutes That Creators Actually Read
Contents
Last quarter I sent the same campaign brief to 12 mid-tier creators — 50K to 200K followers, mostly on Xiaohongshu and Instagram. Eight of them followed it almost to the letter. The other four asked one clarifying question each, in the first 24 hours, and then delivered exactly what I asked for. None of them pushed back on the deliverable. None of them asked for "more creative freedom" in the polite way that means I didn't read the brief.
The brief was one page. 380 words. Generated in 10 minutes with Claude.
Two months earlier, on a similar campaign, I sent a 6-page, 1,800-word brief to 10 creators. Six of them followed it. Two ignored two of the three required talking points. One delivered a post that was technically on-brief and emotionally off-brand in a way I still can't fully describe. One never delivered at all.
The only thing that changed between those two campaigns was the brief.
Why Creators Skip Long Briefs
Here's the math most brand managers don't run. A creator on a flat-fee (固定费用) deal for one sponsored post is typically paid between $300 and $2,000. For that fee, they're spending maybe 4-6 hours total — concept, shoot, edit, caption, revisions, posting. Of those 4-6 hours, they'll spend maybe 15 minutes reading your brief. Maybe 25 if it's actually good.
A 6-page brief is asking them to spend 6% of their paid time parsing your document. A 1-page brief is asking for 2%. The difference shows up in two places: how much of the brief they actually internalize, and how much goodwill they have left when the inevitable "one small tweak" email arrives on day three.
The second reason long briefs get ignored is structural. Brand managers write them like internal project specs — background on the company, category context, "tone of voice" paragraphs, three nested tables of dos and don'ts. Creators don't need 80% of that. They need five things: what to make, who it's for, what to say, what to avoid, and what success looks like.
Everything else is noise that makes the five things harder to find.
The 5 Inputs (4 Minutes)
Before you open Claude, fill in these five slots. They take about 4 minutes if you have a half-debriefed campaign in your head. If you don't, spend 30 minutes first — no prompt will save a brief written from confusion.
Campaign goal — one sentence. "Drive 800 trial signups for our new skincare line among women 25-34 in tier-1 cities." Not "build awareness." Not "drive engagement." A number and a demographic.
Deliverable — what they're actually making. Be specific. "One Xiaohongshu post (5-8 images, 600-900 word caption) and one Instagram Reel (15-30 seconds)." Not "social content." Creators need to know the format before they can think about the message.
Target audience — one paragraph. Who follows this creator, what they're trying to do, what's already in their head. "Urban professional women, 25-34, spent the last 12 months switching between three different moisturizers and are skeptical of 'miracle ingredient' claims."
Three must-say points — the non-negotiable things that have to land in the content. These come from the product marketing brief, not from you. Usually something like: (1) the product solves X, (2) the proof is Y, (3) the offer is Z.
Three don't-say items — the boundaries. Hard no's on competitor mentions, claims you can't legally make, ingredients to avoid, words the brand voice team has flagged. The point isn't to police the creator — it's to save them from making a mistake that costs everyone a re-shoot.
If you can write those five things in 4 minutes, the rest is mechanical.
The Prompt (Paste Into Claude Sonnet)
This is the prompt I use. Replace the bracketed sections with your five inputs. Run it in Claude Sonnet 4.5 — it's fast, cheap (about $0.05 to $0.08 per brief), and handles structured output (a format where the model returns its answer in a defined schema like JSON or a markdown table, not free-form prose) cleanly.
You are a senior influencer marketing manager writing a 1-page brief
for a content creator. The brief must be under 400 words, scannable
in 4 minutes, and follow this exact structure:
# [Brand Name] x [Creator Handle] — [Campaign Name]
## What you're making
- Format, length, platform, posting window
- One line on creative direction (not "be creative")
## Who it's for
- 2-3 sentences on the target audience, including what they
currently believe or do that's relevant
## Three things to say
1. [must-say point 1, with the proof or evidence the creator can use]
2. [must-say point 2, with proof]
3. [must-say point 3, with proof]
## Three things to skip
1. [hard no 1, with a one-line reason]
2. [hard no 2, with a one-line reason]
3. [hard no 3, with a one-line reason]
## What success looks like
- 1-2 measurable outcomes (clicks, signups, saves, comments)
- A 30-day window for evaluation
## Logistics
- Fee, payment terms, usage rights window, content review
process, single point of contact
Voice: direct, warm, no marketing jargon. Assume the reader is
smart, busy, and skeptical of brand-speak. Do not include
background on the company, category context, or "tone of voice"
paragraphs. If any section is unclear from the inputs, write
"NEEDS CLARITY: [specific question]" instead of guessing.
Inputs:
- Brand: [brand name, one-line description, website]
- Campaign goal: [input 1]
- Deliverable: [input 2]
- Target audience: [input 3]
- Must-say points: [input 4]
- Don't-say items: [input 5]
- Logistics: [fee, payment date, usage rights, reviewer, contact]The "NEEDS CLARITY" instruction is the most important line. Without it, Claude fills gaps with confident-sounding filler. With it, you get a brief that tells you exactly what to chase down before sending.
Generate, Then Cut (3 Minutes)
The first output from Claude is almost always 450-600 words. That's the model being comprehensive; it doesn't yet know that you mean "under 400." Your job is the second pass.
Two things to cut first:
- The creative direction paragraph. Claude loves to write a paragraph that says "feel free to bring your own creative angle, we'd love to see your authentic take." Cut it. Replace with a single line: "Show it the way you'd show it to a friend who's been complaining about this exact problem." This is more useful and shorter.
- The "why us" sentence in the success section. Claude will write something like "Success looks like meaningful engagement with our target demographic." Useless. Replace with the number from your campaign goal.
If the brief is still over 400 words, look for adjectives. "Carefully crafted," "premium quality," "innovative formula" — none of these tell a creator anything. They're the filler that survives when the model is padding to length. Delete on sight.
After the second pass, paste the whole thing into a Google Doc (or Feishu / Lark doc if your creators are in mainland China) with a clean template — no logo, no header image, no "brought to you by" footer. Creators will tell you a clean doc signals a professional team. A 14-element branded template signals a brand that doesn't trust them.
The Final 1-Page Template
Once you've cut, the layout should be exactly this, in this order. Creators read top-to-bottom; the order matters.
| Section | Lines | Purpose |
|---|---|---|
| Header (brand × creator × campaign) | 1 | Anchors the document. Tells the creator this brief is about them, not about you. |
| What you're making | 3-4 | Format, length, platform, posting window. The fastest "can I do this?" answer. |
| Who it's for | 2-3 | Aligns the creator's mental model of their own audience with yours. |
| Three things to say | 4-6 | The payload. What has to land. |
| Three things to skip | 4-6 | The guardrails. Saves everyone from a re-shoot. |
| What success looks like | 2-3 | One number, one window. |
| Logistics | 5-7 | Fee, payment, usage rights, reviewer, contact. The "is this person serious?" signal. |
Total: 22-32 lines. Under 400 words. A 4-minute read.
Watch Out For: 5 Mistakes
These are the recurring issues I see when reviewing briefs from junior marketers. Each one costs you completion rate.
Hiding the fee in section 6. Creators want to know what they're getting paid before they read the rest. If the fee is in logistics at the bottom, you've already lost 20% of the brief's attention. Put fee, payment date, and usage rights in the header, not the footer.
Writing the brief for your CMO, not the creator. "Synergize with our Q2 brand narrative" — delete. The creator does not work for your CMO. They work for their audience.
Asking for "authentic content" while specifying eight talking points. These are contradictions. Pick three must-say points. Trust the creator to deliver them in their voice. The eight-point brief is where the off-brand-by-a-mile post comes from.
No review process specified. If the creator doesn't know how many revision rounds they're signing up for, they'll over-deliver in the first draft and you'll get a worse result. State it: "Two rounds of feedback max, each within 48 hours, focused on the three must-say points."
Briefing in English for a Chinese-platform creator. If the deliverable is a Xiaohongshu post, write the brief in Chinese. If the deliverable is an Instagram Reel for a US audience, write the brief in English. The brief's job is clarity. Match the language to the platform.
The Workflow at Scale
For a campaign with 15+ creators, the 10-minute-per-brief math still works — but you batch differently. I write one master brief, run it through Claude 15 times with different inputs, then spend 30 minutes across all 15 outputs doing the second-pass cut. Total time: about 3 hours for a 15-creator campaign. The old way was 6+ hours of writing and still produced a 6-page brief nobody read.
If you're doing this as a recurring workflow, the API (Application Programming Interface — the way you talk to Claude programmatically instead of through the chat interface) version is worth 30 minutes to set up. Anthropic's Python SDK (Software Development Kit) lets you feed the prompt as a template with a CSV (Comma-Separated Values — a plain-text spreadsheet format) of creator-specific inputs. The script is 20 lines; I've pasted the working version at the bottom of this post for subscribers.
A Closing Thought
A brief is a contract. The longer it is, the more it's a contract written by a lawyer who's never run a campaign. The shorter it is, the more it assumes the other side is a professional who'll do their job if you tell them what the job is.
Creators are professionals. They don't need your 6-page "tone of voice" appendix. They need the five things. The Claude prompt above gives you those five things, in the order a creator reads, in under 10 minutes. The rest of your old brief was never useful — it just felt professional to write it.
