Agent Skills

The reusable instructions I give my coding agents, packaged so you can install them with one command. They work with Claude Code, Codex, Cursor and the other agents that read SKILL.md files.

How to install

Run this from your project. It uses the open skills installer, which asks which agents to install for. Add -g to install for every project instead of just this one. 

npx skills add SinghChinmayy/agent-skills --all

Want just one? Each skill below has its own command. Prefer not to run Node? Copy the skill's SKILL.md into ~/.claude/skills/<name>/ (Claude Code) or ~/.agents/skills/<name>/ (Codex and others). Source: SinghChinmayy/agent-skills.

The skills

  1. engineering

    TDD Red-Green-Refactor

    Builds one behaviour at a time with separate red, green and optional refactor commits, so the git history proves every test came before the code. Works with any language or test runner, and includes an honest recipe for testing race conditions.

    Three round characters: a grumpy red one holding FAIL, a happy green one holding PASS, and a smug blue one in sunglasses with a broom.

  2. planning

    Grill Me

    A relentless, one-question-at-a-time interview about your plan. For every question the agent offers its recommended answer, and it explores the codebase instead of asking when it can. You leave with every branch of the design decided.

    A robot with a clipboard asks question 17 of 40 while a sweating developer realises they had not thought about it.

  3. planning

    DB Planning

    Database design in two stages: an interview that walks purpose, entities, access patterns, scale, constraints and operations, then versioned DBML and markdown plans under planning/db/ that you can render as diagrams and iterate on.

    Say plan dbdesign databasedatabase design

    A robot interviewer turns answers into DBML tables and versioned plan files.

  4. engineering

    Modular Development

    Locks the agent to the files you declare, then moves through build, tests, a review gate you control, a scoped merge and a global test check. Stops the 'while I was in there' refactors that leak across a codebase.

    Say modular devscoped buildisolated module/modular

    A robot works inside a fenced sandbox labelled files in scope while the developer holds the key to the review gate.

  5. learning

    Engineering Notes

    Turns photos of notebook pages and quick Markdown notes into one continuous note per topic, in your own words, with visible corrections, a revision block of takeaways and self-check questions, and a diagram only when it helps. Raw pages stay private; the notes are ready to publish.

    Say process my notesprocess the inboxdigest my notesadd this to my notes

    Workflow sketch: notebook pages and Markdown go into an inbox, an agent transcribes and merges them into topic notes and practice files, and CI publishes them to the website.

  6. productivity

    Caveman

    Ultra-compressed replies that keep every technical detail and drop the filler, cutting output tokens by roughly three quarters. Has intensity levels from lite to ultra, and switches back to full sentences for warnings and destructive actions.
