What’s included
Essential Comments
Add, keep, or remove code comments so only remarks that help humans remain - why, invariants, tradeoffs, and external constraints - not narration or restated code. Use when cleaning noisy comments, writing new code, reviewing comment quality, or when the user wants fewer/better comments.
Jane Street Style
Design, refactor, or review code when semantic clarity is the explicit goal, using precise domain names, explicit failures and effects, useful domain types, immutable data flow, and minimal accidental complexity. Use for Jane Street or clarity-first redesign, vague domain APIs, collapsed failures, primitive obsession, or mutation-heavy code - not ordinary bug fixes that should preserve local shape.
Surgical Changes
Implement fixes and small features as the smallest coherent change that fully solves the requested problem. Use when scope control, behavioral preservation, reviewability, or avoiding opportunistic cleanup matters.
Tests That Matter
Write or review tests that prove observable behavior, failure semantics, invariants, and boundary cases. Use when adding tests, fixing brittle or mock-heavy tests, reviewing test quality, or when coverage exists but confidence does not.
Quick start
- Choose your skills. Select individual skills above, or choose the entire pack.
- Copy the install prompt. Use Copy install prompt above the list.
- Send it to your agent. Paste into your coding agent’s chat. Your agent reviews the source and guides the setup.
Try it with your agent
After installation, start with a request like:
Use the Essential Comments skill to help with my task.
Ask me for the context you need before getting started.Requirements & license
- A coding agent that can access your project files and install skills.
- Your agent checks each skill’s instructions, dependencies, and permissions during setup.
- Reported license for the skills shown: MIT. The author’s terms apply.
