What Are Agent Skills?
Agent skills are folders of instructions that coding agents like Claude Code load on demand: a SKILL.md entry point plus reference playbooks, scripts, and eval suites. They follow the open Agent Skills specification, so the same skill works in Claude Code, Cursor, Codex, Amp, opencode, and any other supporting agent.
Ours are distilled from POPJAM's production marketing pipelines: the same data contracts, the same prompts that carry quality, and deterministic scoring scripts so the LLM never does the math. You describe the outcome ("make ads for my site"), and the skill takes your agent through research, strategy, creative, and simulation with evidence at every step.
Four Skills, One Growth Loop
Each skill stands alone, but together they cover research, creative, brand, and rendering.
popjam-growth-engine
MITTurn one website URL into tested ad creatives
Runs POPJAM's full production pipeline inside your agent: brand research → audience segments → a bias-corrected synthetic persona panel → ad angles per audience and platform → real creatives (image, video, animation) → deterministic engagement simulation → iteration. Ends with a leaderboard of who converts and why.
Try: "Make ads for https://yourbrand.com"
Source & docsaward-landing-page
MITDesign and build pages that sell
Landing, pricing, waitlist, and launch pages as one full deliverable: funnel research, art direction, conversion copywriting, distinctive design and motion, technical SEO, and CTA wiring, built to avoid the generic AI-template look.
Try: "Build a landing page for our launch on Thursday"
Source & docsbrand-guideline-extraction
MITReverse-engineer a brand style guide from your assets
Point it at a folder of design assets (posts, ads, banners, decks, videos) and get a complete brand style guide (rules vs. variations vs. exceptions), plus a reusable style prompt block for on-brand AI image generation.
Try: "Extract brand guidelines from ./assets"
Source & docsremotion-render-pitfalls
MITShip Remotion animations that actually render
Render-breaking Remotion mistakes that pass tsc and eslint but crash at render time, battle-tested against POPJAM's production render pipeline. Useful for any strict Remotion setup that generates video programmatically.
Try: "Animate this product demo with Remotion"

Same Pipelines, Managed for Your Team
The skills are the run-it-yourself edition. POPJAM runs the whole loop as a product: brand onboarding from a URL, reusable audiences and persona panels, on-brand ad and content generation for Meta, Google, TikTok, LinkedIn, and Reddit, persona simulation with scored leaderboards, and campaign iteration, all with a team UI, asset storage, and integrations on top. If your marketing team doesn't live in a terminal, this is the version for them.
Frequently Asked Questions
What are agent skills?
Agent skills are folders of instructions (a SKILL.md file plus optional reference playbooks and scripts) that coding agents like Claude Code load on demand when a task matches. They follow the open Agent Skills specification (agentskills.io), so one skill works across Claude Code, Cursor, Codex, Amp, opencode, and other supporting agents. Think of them as installable expertise: instead of prompting from scratch, your agent follows a battle-tested playbook.
Are POPJAM's agent skills really free?
Yes. All four skills are open source under the MIT license at github.com/popjam-io/skills. There is no signup, no trial clock, and no POPJAM account required. You run them in your own agent, so the only cost is whatever your agent provider charges for model usage.
How do I install the POPJAM skills in Claude Code?
The fastest way is the skills CLI: run `npx skills add popjam-io/skills` and pick the skills you want. In Claude Code you can also use the plugin marketplace: `/plugin marketplace add popjam-io/skills` followed by `/plugin install popjam-skills@popjam`. Or clone the repo and copy any skill folder into ~/.claude/skills/ (or your project's .claude/skills/).
Which AI agents support these skills?
Claude Code, Cursor, Codex, Amp, opencode, and any other agent that implements the Agent Skills standard. The skills are plain instruction files, so they don't depend on any POPJAM infrastructure.
Do I need POPJAM to use the skills?
No. The skills run standalone in your agent and persist their outputs to local files. Some phases of the growth engine generate real media (images and video use the Higgsfield MCP, and animations use Remotion), and if neither is available, the skill still delivers audience strategy and persona simulation on text concepts, honestly labeled as such.
What's the difference between the skills and the POPJAM platform?
The skills are the run-it-yourself edition of the same pipelines: brand research, audience discovery, synthetic persona panels, creative generation, and engagement simulation, running in your terminal and writing to files. The POPJAM platform runs that loop as a managed product: brand onboarding from a URL, reusable audiences and persona panels, ad and content generation, scored simulation leaderboards, campaign iteration, all with a team UI, asset storage, and integrations. The free tier gives you 500 credits with no credit card.
