What is a Claude Skill?
A Claude Skill is a markdown file (SKILL.md) with structured instructions Claude loads when relevant. Think muscle memory: instead of pasting the same prompt every time you write a PR description, you install the pr-description-writer skill once. Claude will use it whenever you ask for a PR description.
Each skill is 250–450 words of opinionated guidance: required inputs, structure to follow, anti-patterns, output format. They're not generic prompts — they're hand-written for specific recurring tasks like investor updates, postmortems, QBR prep, or contract drafts.

name: pr-description-writer
description: Use when writing a pull request description from a diff.

# PR Description Writer
Write PR descriptions that reviewers actually read. Lead with the why,
not the what — diff hunks already show what changed.
## Required inputs
1. The diff (or branch name)
2. The ticket / issue link
3. Any non-obvious context the diff doesn't reveal
## Structure
- TL;DR (1 sentence)
- Why
- What changed (high level, NOT line-by-line)
- How to test
- Risks & rollout
...Skills vs. one-shot prompts
Prompts (/prompts)
- • Copy / paste each time
- • Ad-hoc tasks
- • You drive the structure
- • Best for one-off work
Skills (/skills)
- • Install once
- • Recurring workflows
- • Skill enforces structure
- • Best for repeat work
Rule of thumb: write a press release once, use a prompt. Write press releases every other week, install the skill.

Safety note
Every skill on this site is pure markdown— no bash scripts, no executable code, no pre-approved tools. You can open any of them in a text editor and read everything Claude will see. That's a deliberate choice.
The broader Claude Skills standard doesallow bundled scripts and tool pre-approval, which means a skill from an untrusted source could direct Claude to do things you didn't intend. Anthropic's own security guidance recommends auditing any skill before installing — including ours. Read what you install. Always.

Why we built this
Most Claude Skills you'll find online are either generic stubs (one-line YAML, no real instructions) or behind a paywall. We wrote each of these by hand for specific, recurring B2B knowledge work — the kind of tasks you do 10x a week and shouldn't be re-prompting from scratch.
Free to use, free to share with credit. Site code is MIT, content is CC BY-NC (non-commercial use OK). New packs added monthly. Want a specific skill or pack? Email hello@ainews.tech.
