# Startup Skills: Matt Silverlock > Every skill by Matt Silverlock in the index, with a line saying when to use each one. I index these, I do not host them. Every entry points at the original author's repo and carries a source byline. ## Entries (4) - [Code reviewer](https://github.com/elithrar/dotfiles/blob/main/.agents/skills/code-reviewer/SKILL.md) by Matt Silverlock: Use when one specific diff must be read for defects, with no wider audit. - [Create README](https://github.com/elithrar/dotfiles/blob/main/.agents/skills/create-readme/SKILL.md) by Matt Silverlock: Use when an open source project's README needs writing or rewriting. - [Prompt engineer](https://github.com/elithrar/dotfiles/blob/main/.agents/skills/prompt-engineer/SKILL.md) by Matt Silverlock: Use when a system prompt or tool description causes over-searching, format drift or conflicts. - [Web perf](https://github.com/elithrar/dotfiles/blob/main/.agents/skills/web-perf/SKILL.md) by Matt Silverlock: Use when diagnosing slow loads or layout shift from browser traces and network evidence. ## Links - [Page](https://startupskills.dev/elithrar): the same list, for a person. - [The whole index](https://startupskills.dev/llms.txt): all 189 entries. - [Skills index](https://startupskills.dev/skills): every skill, with search.
