Free vs Pro

What's free, what's Pro, and what happens if you stop

Free (80)

Editing (photo, video, music), document conversion, watch-video, and core email safety. Yours to keep with a one-time setup; no subscription needed.

Pro (40) subscription

The full security suite (link, attachment, secret, dependency, MCP, OAuth, DNS scanning + the supply-chain scanner), document generators (docx/pptx/xlsx), business strategy, advisors, premium creator tools, and the nonprofit / consultant / MSP vertical packs.

Every paid plan gets the full set."Pro" is not a separate skill tier you pick: Solo, Personal Sync, Team, and Business all include the complete catalog of 120 skills. Plans differ by how many machines they cover and the level of support, not by which skills you get.

One-time setup (from $299): configures your machine and installs the free pack to keep; the Pro catalog needs a subscription. If you stop: you export your vault keys, the Pro skills are uninstalled (reversibly), and you keep your files, projects, your own skills, the free pack, and your Claude subscription. We never hold a copy of your keys. See the FAQ and pricing for the full terms.

Yours to manage

Pick and choose, during setup or any time later

A built-in Skill Library lets you browse every skill, read what each one does and how to use it, and install or remove individual skills, with no terminal. Choose your set during the first-run wizard, or open the Library from the app whenever you like.

What it manages

Only skills ClevSkill installs: our own (proprietary) skills and the curated third-party / marketplace skills we package. Your own skills are never listed or touched. Removing a skill is reversible, and Pro skills need an active subscription.

New skills, offered not forced

When we add skills in an update, the app tells you and lets you choose; nothing installs without your say-so. Skills you keep update automatically, and a skill you remove stays removed until you add it back. Your choices carry across updates.

Optional add-ons

Open-source add-on packs, include them in one step

Beyond the ClevSkill catalog, you can add these curated open-source packs during setup or any time from the app. Each is free (MIT-licensed) and installed from its public source, with attribution. They are kept separate from our own skills, and you choose which to include.

ECC agent harness

Free, MIT

Memory, instincts, security guidance, and multi-agent orchestration (the affaan-m/ECC harness). Adds the layers gstack does not cover.

Business skills bundle

Free, MIT

Source: github.com/sickn33/antigravity-awesome-skills

Compliance, finance and C-suite pack

Free, MIT

27 business-function skills: compliance audit-prep (ISO 27001, SOC 2, GDPR, FDA QSR, EU AI Act), finance modeling, and C-suite advisory, from the alirezarezvani/claude-skills library.

Source: github.com/alirezarezvani/claude-skills

doc-to-skill

Free, MIT

Turn a PDF, SOP, or policy manual into a reusable Claude skill, entirely on your machine. Nothing leaves the device, ideal for confidential internal docs.

Source: github.com/virgiliojr94/book-to-skill

Pick the ones you want during the first-run wizard, or add them later from the app. They install from their public repositories and never overwrite a skill you already have. ECC also adds global coding rules that load each session, so it is offered, not forced.
