Smidge (smdg.app) takes source material and produces production-ready skills compatible with the open Agent Skills spec. Works with Claude, Cursor, Copilot, and 30+ AI agents.

The core idea: your agents should have the same expertise you do, without you manually writing SKILL.md files.

How it works:

Drop source material (YouTube, PDFs, audio, docs, slides, up to 50MB each, multiple sources at once)

Source-aware extraction: transcripts get distilled, papers keep structure, slides get expanded

Automatic skill catalogues: a textbook or manual becomes multiple focused, topic-specific skills

Every skill validated against the Agent Skills spec Download individual skills or full catalogues

CLI: npm i -g smdg-cli smdg generate --source ./docs/brand-guide.pdf

Tech: Next.js, Supabase (Postgres + Auth + Storage), Claude API for extraction, Stripe for payments.

Two free generations. Credit packs start at $9 for 5 skills. $19/mo unlimited.

I built this because I wanted my coding agents to have domain expertise from my existing materials. The extraction engine is source-aware: it adjusts its strategy based on whether it's processing a transcript, an academic paper, a framework doc, or a slide deck. For large inputs, it automatically detects distinct topics and produces a catalogue of focused skills instead of one monolithic file. Happy to answer technical questions about the extraction pipeline or the Agent Skills spec.
