Claude Code skills for trade pros

Stop paying for software. Pay for the skill.

Production-grade Claude Code skill packs that turn your AI into a specialist. Built by operators with 20+ years in the field — not vibe coders. Drop into ~/.claude/skills/ and your AI knows your trade.

Why Stackio

Generic AI gives generic answers. A trade-specialized AI cites NEC, calculates Manual J, and reconciles METRC the way a senior would.

01

Operator-built

Every pack is written by someone who's billed hours in the trade. No fluff, no LLM-generated padding — just the tables, formulas, and templates that move work.

02

Cites its sources

Every code answer cites the article. Every calc shows the formula. Every recommendation flags the caveat. You stay accountable, the AI stays honest.

03

Drop-in install

Unzip into ~/.claude/skills/. Restart Claude. Done. Works with Claude Code CLI, the Desktop app, and the VS Code extension.

04

Free updates for 1 year

NEC changes. METRC changes. SEER becomes SEER2. You get every update we ship for 12 months, automatically, by email.

Skill Packs

Five packs. One-time payment. Use across every project on your machine. No subscription, no seat limit, no token-per-query nonsense.

Common questions

Will this work with my Claude subscription?

Yes — skills are a feature of Claude Code (CLI, Desktop, IDE extension). You don't need a separate API key. Skill packs work with any active Claude plan.

Is this a subscription?

No. You pay once per pack, you own it forever. We include 12 months of free updates by email. After that, updates are optional and discounted for prior buyers.

Can I use a pack on multiple machines?

Yes. One purchase = personal license across all your machines. Team / business licenses available — email hello@stackio.ai.

What if a pack doesn't work for me?

30-day refund. No questions. Email hello@stackio.ai and we'll process it. The skills are good — but we'd rather give your money back than have you mad at us.

Who wrote these?

Stackio is run by Lee Snedaker, an Austin-based engineer with 20+ years in electrical, controls, and cannabis cultivation. Specialty packs (HVAC, compliance) are co-written with subject-matter experts under NDA.

Can I commission a custom pack?

Yes. We build custom skill packs for trades, brands, and enterprises. Typical custom pack: $5–$25K depending on scope. Email hello@stackio.ai.

Are these AI-generated?

The skills are written by humans with help from Claude for formatting and consistency. Every formula, table, and reference is human-verified against the source (NEC, ACCA, state regs, lab data). We won't ship a fake citation.
