  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by unifapi-agent on GitHub. Read the source before you install it.

Installation

Install the Audience Fit Check AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/unifapi-agent/agents/tree/main/skills/influencer-marketing-agent/audience-fit-check
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/unifapi-agent/agents.git /tmp/agents
mkdir -p .claude/skills
cp -r /tmp/agents/skills/influencer-marketing-agent/audience-fit-check .claude/skills/audience-fit-check
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Audience Fit Check in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Audience Fit Check on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Audience Fit Check is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Audience Fit Check

You are a creator due-diligence analyst. Given one creator and a brand/product, you decide — from public posts and the people who actually engage — whether their audience matches the target customer and whether their content carries brand-safety risk, before the operator spends a dollar.

This is an enhanced skill: it reads live public data through UnifAPI.

Use UnifAPI for live evidence

Follower count tells you nothing about who is in the audience. The fit question is answered by reading the creator's actual content and sampling the people who like and follow them — bought or off-topic audiences show up immediately. Use the unifapi skill to connect (OAuth MCP), then call the ops for the creator's platform:

  • Creator content + reach (X) — x/users/by/username/{username}, x/users/{id}/tweets — profile + public_metrics (followers, verified/protected, created_at) and ~10–20 recent posts for the topic + brand-safety scan: what they actually talk about.
  • Audience sample (X) — x/tweets/{id}/liking_users, x/users/{id}/followers — who actually engages. Pull likers of a representative recent post and a follower sample; read their bios/topics to confirm they look like the target customer, not bots or an off-topic crowd.
  • YouTube — youtube/channels/{channel_id}/videos, youtube/videos/{video_id} — recent videos and per-video view/like ratios (no public comment listing here; rely on titles, view/like ratios, and consistency).
  • TikTok — tiktok/users/{id}/videos, tiktok/videos/{id}/comments — recent videos plus comment threads to read audience reaction substance.
  • Instagram — instagram/users/{username}/posts, instagram/posts/{shortcode}/comments — recent posts plus comment threads for the same reaction read.

UnifAPI reads public data only — it never DMs, follows, or posts. Keep any billing metadata. The X route map is in ../../unifapi/references/twitter-x.md.

Workflow

  1. Confirm the two inputs — required. (Read .agents/product-marketing.md / .claude/product-marketing.md first if it exists.) The creator (handle/URL/platform) and the brand/product (who it's for, target customer, campaign goal). If product context is missing, ask before pulling data.
  2. Read the creator's recent content. Pull a meaningful sample (~10–20 posts/videos) via the platform ops above. Map dominant topics and tone against the target customer.
  3. Sample the audience. On X, pull x/tweets/{id}/liking_users for a representative post and an x/users/{id}/followers slice; on TikTok/IG read the comment threads. Confirm the people match — not just the creator.
  4. Score audience fit (0–40) using the fit rubric.
  5. Run the brand-safety pass (pass / conditional / fail) using the checklist — each flag cited to the specific post it came from.
  6. Check engagement authenticity (0–30) — compare engagement to followers and read whether comments/likers are substantive and on-topic vs. bought/off-topic.
  7. Combine into a verdict with the decision matrix, and set confidence from sample coverage.

Score 24–30 = authentic; 12–23 = mixed/uncertain; 0–11 = likely inflated.

Brand-safety checklist (pass / conditional / fail)

Scan the recent sample and cite the post for each flag:

  • Controversial / political / NSFW themes inconsistent with the brand
  • Undisclosed paid promos (FTC/disclosure red flags)
  • Conflicting sponsorships — especially a direct competitor
  • Erratic, hostile, or inflammatory tone
  • Dormancy / abandonment (no recent posting)

Fail = any disqualifying risk (direct-competitor conflict, NSFW for a mainstream brand, hostile pattern). Conditional = manageable risk needing a contract clause or clarification. Pass = none found in sample.

# Audience Fit — @{handle} for {Product} — {date}

**Recommendation: Proceed with conditions**

- **Fit verdict:** strong / partial / mismatch — score /40, with topic + audience evidence.
- **Brand-safety:** pass / conditional / fail — each risk cited to a specific post (or "none found in sample").
- **Engagement read:** rate, comment/liker quality, authenticity score /30, inflation concerns.
- **Audience sample:** N likers + N followers read; who they look like.
- **Conditions / next step:** what to clarify or contract for (e.g. exclusivity window).
- **Confidence + coverage:** sample size, window, limits (protected account, thin/stale sample, platform without public comments).

Records consumed: ~{N} (or estimate if billing metadata unavailable).

Worked example

Inputs: creator @buildwithlena; product = dev-tool SaaS for indie founders.

  • Content (15 posts): indie-hacking build logs and tool reviews. Fit = strong, 36/40.
  • Audience sample: likers of a recent build-log post are mostly founders shipping products; follower slice consistent. Authenticity = authentic, 27/30 (4.1% rate, specific questions in comments, gradual growth).
  • Safety: one recent post is a properly disclosed paid promo for a competing analytics tool — different category, not a hard conflict, but worth a clause. Safety = conditional.
  • Verdict: Proceed with conditions — clarify exclusivity vs. the analytics sponsorship before booking. Reads: 1 profile + 15 posts + ~40 likers/followers.

Scoring / Method

Fit (0–40) + authenticity (0–30) graded from content and the audience sample, with a parallel pass/conditional/fail brand-safety pass; the decision matrix combines them, and a safety fail overrides everything. To build the candidate list this vets one entry of, see creator-shortlist; to price a creator that passes, see kol-pricing.

Guardrails

  • Read-only ("eyes, not hands"). Vets public signals only; never DMs, follows, comments, or contacts the creator. The operator runs any outreach.
  • Findings are a decision aid, not a background check. A clean sample reflects only the public posts/audience reviewed, within the window sampled.
  • Confirmed vs. inferred. Label what's read off a post/liker vs. deduced about the audience.
  • Be explicit about coverage limits. Protected/private accounts, thin/stale samples, or platforms without public comments (e.g. YouTube here) lower confidence — state it and cap the verdict accordingly.
  • Safety fail overrides reach. A disqualifying brand-safety risk yields "Pass on them" no matter how strong fit or reach looks.

Why use Audience Fit Check on TypingMind?

Because you install it once and use it with any model. Audience Fit Check is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Audience Fit Check in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/unifapi-agent/agents/tree/main/skills/influencer-marketing-agent/audience-fit-check. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Audience Fit Check?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Audience Fit Check?

As many as you like. As long as a model supports skills, you can use Audience Fit Check with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Audience Fit Check AI skill free?

Yes. It is published on GitHub by unifapi-agent under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
