cskwork/skills

The agent skills, system prompt, and CLI toolkit I use every day with Claude Code, Codex, and other coding agents.

Landing page: https://cskwork.github.io/skills/ · 한국어 요약은 아래에 있습니다.

Install

Pick the skills you want, and which agents to install them on:

npx skills@latest add cskwork/skills

List them without installing:

npx skills@latest add cskwork/skills --list

Install the system prompt (back up your existing ~/.agents/AGENTS.md first):

mkdir -p ~/.agents ~/.claude ~/.codex
curl -fsSL https://raw.githubusercontent.com/cskwork/skills/main/system-prompt/AGENTS.md -o ~/.agents/AGENTS.md
ln -sfn ~/.agents/AGENTS.md ~/.claude/CLAUDE.md
ln -sfn ~/.agents/AGENTS.md ~/.codex/AGENTS.md

Caveman default

Install the local voice skill:

npx skills@latest add cskwork/skills --skill caveman -g

The included system prompt enables Caveman by default. If you keep your own prompt, add: "Use the caveman skill by default for user replies; explicit style requests override this default." Say stop caveman or normal mode to disable it for the session. attention-kind remains available on request. This installs the voice skill only; it does not install the Caveman proxy, routing, or telemetry.

System prompt

system-prompt/AGENTS.md is the operating contract I give every coding agent: agree on outcome and scope, ground decisions in evidence, verify, and report plainly. Source of truth: cskwork/THE-SYSTEM-PROMPT.

Skills

Engineering

Skill	What it does	Source
sdlc-kit	Four-phase SDLC loop (intent → plan → build → evidence) with human gates, adversarial review, and scored, routed proof.	cskwork/sdlc-kit
verify-app	Build and run the app to prove a change works end to end. For agents without a built-in verify, such as Codex.	this repo
bughunt	Find and fix interaction bugs with seeded personas, invariant oracles, and failure replay. App profiles for games, CRUD apps, AI chat, and media; Godot, native iOS, and web adapters.	cskwork/bughunt-skill
quality-loop	Product quality bar and improvement loop: scores UI/UX, function, consumer trust, and engineering against hard floors, gates release candidates with an independent judge, ratchets every fix in a ledger, and reports quality as a % (target >= 90%) with the reason for each lost point.	cskwork/quality-loop-skill
db-intelligence	One skill for PostgreSQL, MySQL, SQLite, and MongoDB: detect the engine, connect credential-safe, read schema, read before writing, never write to prod.	cskwork/pi-setup-public
sql-walkthrough	Explain SQL/batch logic to a non-expert: numbered source lines, the real rows they read, per-line arithmetic, a results table, and an executed counter-example.	cskwork/sql-walkthrough
improve-codebase-architecture	Find deepening opportunities, show them as an HTML report, then grill through the one you pick.	mattpocock/skills
grill-with-docs	Relentless design interview that sharpens a plan while keeping GLOSSARY.md and ADRs updated as decisions settle.	mattpocock/skills
domain-modeling	Actively build and sharpen a project's domain model in GLOSSARY.md and docs/adr/.	mattpocock/skills
research	Investigate a question against primary sources in a background agent and record cited findings in Markdown.	mattpocock/skills
prototype	Build a throwaway prototype to answer a design question.	mattpocock/skills
retro	Run a retrospective on a coding session.	mattpocock/skills
jk	Drive Jenkins from the terminal with the jk CLI: jobs, runs, logs, artifacts, credentials.	avivsinai/jenkins-cli
swiftui-pro	Review SwiftUI code for modern API use, data flow, navigation, accessibility, and performance, with before/after fixes. Pairs with mobile-ui-ux.	twostraws/SwiftUI-Agent-Skill
simless	Default way to test iOS apps: render SwiftUI screens as accessibility trees, hot-reload views, and run unit tests on the Mac without a simulator; the simulator is kept for the final pass.	abacusai/simless

Productivity

Skill	What it does	Source
grilling	Interview the user in frontier rounds until a plan or design tree is settled with nothing silently assumed.	mattpocock/skills
caveman	Default terse reply style: answer first, preserve technical facts and exact payloads. Local voice skill only.	JuliusBrussee/caveman
attention-kind	Answer in the ADHD-friendly Attention-kind style: one-sentence bottom line first, arrow-marked bold points, short by default, expanding only on what is vital while preserving numbers, conditions, and warnings.	alexgreensh/attention-span
handoff	Compact the conversation into a handoff document for another agent.	mattpocock/skills
writing-for-agents	How to write skills, AGENTS.md, and CLAUDE.md for agents.	mattpocock/skills
ponytail	Lazy-senior-dev mode: the simplest, shortest solution that actually works.	DietrichGebert/ponytail
work-status	Report progress on the current request in numbers: items done, in progress, todo, and blocked, evidence for each done item, and an ETA for the rest.	this repo

Design

Skill	What it does	Source
impeccable	Design, critique, audit, and polish frontend interfaces.	pbakaus/impeccable
gpt-image-2	Generate and edit images with ChatGPT's current image model through your ChatGPT plan and the Codex CLI. Model-agnostic: follows whatever model Codex uses.	agentspace-so/agent-skills (modified)
diagram-design	44 diagram and chart types (architecture, flowchart, sequence, state, ER, timeline, Sankey, and more) as self-contained HTML/SVG/PNG, with Mermaid, .drawio, and .excalidraw import.	cathrynlavery/diagram-design
motion-graphics	Code-driven motion-graphics videos: product launch videos (Apple/Google keynote style) from real captures of your running app, and vertical YouTube Shorts, Reels, and TikTok.	cskwork/motion-graphics-skill
mobile-ui-ux	Measurable UI/UX rules for iPhone apps, mobile web, and mobile games (touch targets, safe areas, contrast, Korean line breaks, HUD and combat readability), plus a 7-category scoring rubric, an independent-judge prompt, a pre-ship checklist, and per-project overrides. Pairs with impeccable.	written in this repository
image-first-ui	Image-first UI: three UX-distinct interface options generated as images through your ChatGPT plan; the one you pick becomes the reference the real build must match. Adds production sizing, stack choice, a domain pattern list, and a release gate with an independent judge. Admin, web app, landing page, or game screens.	written in this repository (image scripts from gpt-image-2)

Agents

Skill	What it does	Source
call-agent	Delegate a bounded task to a peer CLI: Codex, Claude, Antigravity, Kiro, NotebookLM, ChatGPT Pro.	cskwork/call-agent

Installed from their own home

These skills ship with a tool or a machine setup, so get them from their own home instead of copying them here.

Skill	What it does	Install
verify	Claude Code's own /verify: builds and runs your app to confirm a change does what it should.	Comes with Claude Code (v2.1.200+). Type /verify.
ego-browser	Browser for agents that shares your logged-in sessions (ego-lite).	Install the ego lite app, or npx skills add citrolabs/ego-lite
teams-native-chat	Send text and clickable links through the signed-in Teams web client's native chat service, without Microsoft Graph or webhooks.	Install from the linked standalone repository.
hindsight	Shared long-term memory for Claude Code, Codex, Hermes, and Pi (hindsight-agent-setup).	curl -fsSL https://raw.githubusercontent.com/cskwork/hindsight-agent-setup/main/bootstrap.sh | bash

Toolkit

The CLIs around the agents: account switching, status line, Google Workspace, Firebase, Jenkins, agent runtimes, shell output compression (rtk), and my Pi setup. See toolkit/README.md.

Licenses

My own files are MIT (LICENSE). Vendored skills keep their own license file in their folder; see THIRD_PARTY.md for sources and the exact commits copied.
