"I hope this email finds you well. I wanted to reach out to discuss the possibility of potentially exploring a partnership opportunity that could be mutually beneficial for both our organisations. Please don't hesitate to reach out if you have any questions."
"Hi Sarah — I saw GreenGrid's case study with Tata Steel. We help manufacturers cut energy waste using AI monitoring. Would a 15-min call next week make sense to see if there's a fit?"
Same task. Same AI. Different skill loaded.
Skills that compound into workflows
One skill saves you the hours it took us to build, test, and refine it. The pillar around it makes the next task connect — so the value stacks instead of stopping at the file.
saved per skill, per use
Each skill encodes hours of prompt engineering, edge-case handling, and output structuring. You skip straight to results.
at typical consulting rates
A single well-crafted business proposal, strategy doc, or marketing campaign would cost 10× what the full library costs.
every skill, every version
Each skill goes through 3 automated improvement cycles with adversarial testing. You get the version we wouldn't be embarrassed to ship.
Without Skill Locker
- Spend 30 mins writing a prompt, get a generic output
- Iterate 4–5 times to get something usable
- Start from scratch every time for a new task
- No quality floor — results vary wildly
- You’re the prompt engineer, the editor, and the QA team
With Skill Locker
- Describe the task — the skill handles the structure
- First output is polished, structured, and specific
- 297 skills covering 31 domains, ready to go
- Built-in quality gates, edge-case handling, and output formats
- You focus on the work. Claude handles the craft.
Most users tell us a single skill saves them more time in a week than the entire library costs. That's before they discover the rest of the library.

People are shipping faster
Early users are already seeing the difference in their daily work.
I was spending 20 minutes per email crafting prompts. Now I just say 'write a cold outreach to this person' and the output is better than what I was getting after 5 revisions.
Sarah K.
Freelance Consultant
The strategy skills alone are worth the full price. I used the competitive analysis skill for a client pitch and it produced a framework I'd normally charge £2k to build manually.
Tom R.
Strategy Director
I bought the Ops & Process bundle for my team. The SOPs and process docs Claude produces now are genuinely usable — not the generic fluff you normally get from AI.
Priya M.
Operations Lead
As a solo founder I'm wearing 10 hats. These skills basically give me a marketing team, a copywriter, and a business analyst on tap. Best $299 I've spent this year.
James L.
Startup Founder
Built with rigour, not vibes
