See and drive the sibling agent sessions running alongside you on this machine via the termiod CLI — list them and their status, start a new agent or plain-terminal session, send a prompt or an answer into one, and set your own status. Use when delegating work to another session, or checking on what other sessions are…

See and drive the sibling agent sessions running alongside you in this Termio project via the termio sessions CLI — list and watch their status, spawn new agent or plain-terminal sessions, send a prompt or an answer into a session, and read an agent's reply from its transcript. Use when delegating work to another…

Reverse-lookup glossary that turns a vague description of a web animation or motion effect into its exact term ("the bouncy thing when a popover opens" → Pop in; "the iOS rubber-band scroll" → Rubber-banding). Use when the user asks "what's it called when…", or describes a motion effect without knowing its name and…

Drive the running termio app via AppleScript / System Events to reach a UI state (focus the window, click a sidebar project, a terminal pane, a control), capture a pixel-accurate screenshot of just that window, and read it back for visual analysis — for diagnosing layout / spacing / alignment / 'this looks ugly'…

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading)…

A release procedure for termio, a macOS app, that creates a numbered Git tag on the main branch. A Git tag is a permanent label for a specific version of the code.

Check whether ghostty (the terminal core termio embeds via the termio-sh/libghostty-swift fork) has shipped anything worth pulling since the binary termio is currently pinned to. Resolves the pinned ghostty sha, diffs it against ghostty main, filters the gap for changes that actually reach termio's embedded…

Cut dead code and over-long comments from termio's Swift, verifying every deletion against a build. Knows this repo's real failure mode (essay-length doc comments, not restated-code slop) and periphery's four known false-positive shapes. Invoke when the user says 'clean dead code', 'clean up the comments', 'the…

Analyze / reverse-engineer the locally installed Dia Browser mac app (The Browser Company; bundle id company.thebrowser.dia; shares ArcCore with Arc). Inspect its app bundle, extract its Bun/TypeScript agent-server source from shipped source maps, fingerprint the runtime, read native-Swift symbols, and map its…

Use for ANY operation on a doc under docs/ — creating, updating/editing, changing its status, or querying. Keeps the YAML front matter (title/status/type/updated) correct and regenerates the docs/README.md wiki index. Invoke when the user says 'new doc', 'create a doc/design/RFC', 'start a design doc', 'update the…

This skill encodes Emil Kowalski's philosophy on UI polish, component design, animation decisions, and the invisible details that make software feel great.
Skill Claude CodeCodex
Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks "what could be animated here?" or wants to "make this feel more alive". For fixing existing animations, use…

Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the…

A development workflow for rebuilding the TermioMobile iOS app and launching it on a connected iPhone or simulator. It connects the app to the companion server running on the Mac.

A guide for turning unclear user feedback from text, chat excerpts, or screenshots into a focused GitHub issue, a tracked software-work item. It preserves the original request and separates evidence from information that is still unknown.
Skill Claude CodeCodex
A macOS development helper that stops the running Termio development app, rebuilds it with Swift Package Manager, and opens it again. It keeps the development app separate from the installed release app.

Profile native macOS/iOS apps using Time Profiler via CLI (xctrace). Use when asked to identify performance hotspots, profile CPU usage, or diagnose slow code paths without opening Instruments.

Pick the right library for a given frontend task from a curated, opinionated list — numbers, OTP inputs, charts, command menus, virtualization, drag and drop, toasts, state, styling, and more. Only runs when explicitly invoked; it does not trigger on its own.
Skill Claude CodeCodex
Build multiple genuinely different versions of a UI piece you describe, rendered behind a visual picker so you can flip through them live and promote the one that feels right. Only runs when explicitly invoked; it does not trigger on its own.
Skill Claude CodeCodex
Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.

Review and fix user-facing copy against termio's voice guide (VOICE.md), scoring each pass and iterating until it holds. Covers UI strings, landing site, docs, release notes, and PR or issue text. Use when the user says 'review this copy', 'does this sound like us', 'check the wording', 'audit the settings text', 'fix…
