Skills.
A skill is a small file of instructions that teaches your AI to do one job well, your way, every time. These are ones we actually use. Take them, change them, make them yours.
Using one takes a minute
Skills run natively anywhere Claude does: Cowork, claude.ai, and Claude Code. The instructions inside work in ChatGPT and Gemini too. Pick a skill below, read it, then set it up your way:
In Cowork or claude.ai
Save the copied text as SKILL.md (or grab the zip where offered), then go to Customize → Skills → upload. That's it.
In Claude Code
Paste it into a new file: ~/.claude/skills/<skill-name>/SKILL.md and start a new session. It's live.
In ChatGPT or Gemini
The auto-loading is a Claude thing, but the instructions inside a skill are just plain prompt. Drop the text into a ChatGPT Custom GPT or Project, or a Gemini Gem, and it runs every time. Paste it at the top of a one-off chat for a quick go. You lose the automatic trigger, you keep the recipe.
Skills from the Shed
Every card has a risk bar: the fewer segments lit, the less of your machine the skill can touch. Low risk means quick to verify, not safe to skip reading.
Pitch analysis
Reviews a sales call you've had, or preps you for the next one. One thing to keep, one thing to change.
Best for: Anyone who sells and has a call transcript sitting in their notes app.
reads: transcripts and deal notes you give it
Package this up
Turns rough notes into a clean web page, in your own brand.
Best for: Anyone who has to send the findings, not just find them.

The challenging advisor
Disagrees with you on purpose, so you think harder.
Best for: Anyone whose AI tells them every idea is brilliant. Which is everyone.

A tune-up that measures what your AI setup costs, then makes it cheaper without making it worse.

Strict code review
An unusually tough second pair of eyes on what you build.

Build your own
Build your own in three steps
- 01 Copy the template below into a new file:
~/.claude/skills/your-skill-name/SKILL.md - 02 Fill it in. Plain English works. Write it like you'd brief a sharp new colleague.

Built something useful?
Bring it to the next Shed and show it, or email it to hello@bristolaished.com. If it's good, it goes up here with your name on it. That's the whole deal: take what's useful, share the next thing.
