The actual app — click projects, switch tabs, toggle skills.

Works where you work

One toggle. Every IDE.

SkillOS writes the file your editor already reads. No plugins. No custom protocol.

Modular by design

Skills are small. So your context stays sharp.

Each Skill is a focused snippet with a token budget. Mix them per project, per task, per teammate.

Concept extraction

Let Claude read your repo.

Point SkillOS at any project. Claude scans the file tree, reads the ranked anchor files — schemas, configs, routes — and returns a set of structured concept cards: domain entities, user flows, integrations, and the gotchas a new contributor would otherwise learn the hard way.

stack
package.json

Next.js 15 · Drizzle · Supabase · Stripe

App Router with Server Actions, Drizzle over Supabase Postgres, Stripe Billing for subscriptions.

entity
packages/db/src/schema.ts

Subscription

Mirrors stripe_subscription. Tracks plan, status, seats, renewal date, current period end.

page
apps/web/src/app/checkout/page.tsx

/checkout

Plan selector + Stripe Elements. Server Action creates session, redirects to Stripe-hosted page.

integration
apps/web/src/app/api/webhooks/stripe/route.ts

Stripe webhooks

POST /api/webhooks/stripe verifies signature; handles invoice.paid, subscription.deleted, .updated.

convention
apps/web/src/app/_actions/

Server Actions only — never API routes

All mutations go through app/_actions/*. Each action validates input with zod before touching the DB.

Built for teams

Context is collaborative now.

Skills and concepts live in workspaces — your personal one, and the ones your team shares. Fork to customize, request edits to propose changes, and let the tech lead push canonical updates so the whole org is reasoning with the same brain.

Fork & customize

Take any org skill private. Edit it for your slice of the codebase. Pull updates from the parent when you want them.

Request edits

Propose a change to a teammate's skill with one click. Reviewed in-app — no PR-shaped overhead for a 12-line markdown file.

Push forced updates

Tech lead pins a new version of typescript-strict. Every laptop in the org picks it up before the next prompt.

Three sides

Built for the whole loop.

Developers ship faster. Tech leads stay in control. Vendors finally measure how AI uses their docs.

For developers

Toggle. Generate. Ship.

Click a preset for the stack you're working in. Your IDE picks up the new rules natively — no plugins, no custom CLI.

For tech leads

Curate the org's brain.

Define the canonical stack. Push forced context updates so the whole team is coding with the same rules.

For vendors

Ship verified Context Packs.

Publish official Skills for your API. Stop hallucinated snippets, get real telemetry on how agents use your docs.

Get the alpha.

We're onboarding a small group of developers and vendor partners. Tell us who you are and we'll send a build that already understands your stack.
