Patterns for building and debugging TabzChrome itself. An agent skill from GGPrompts/TabzChrome.

  • Working on Terminal.tsx
  • SKILL.md covers Core Architecture, Key Files, Quick Patterns and References
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Xterm.js integration

What it does

Tabz Development is an agent skill from GGPrompts/TabzChrome. Patterns for building and debugging TabzChrome itself. Use when working on Terminal.tsx, xterm.js integration, WebSocket I/O, resize handling, or any TabzChrome extension/backend code.

Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/resize-handling.md`, `references/testing-checklist.md` and `references/websocket-io.md`).

It sits in Backend & APIs, covering Realtime and WebSockets and React components. The repository describes itself as: Chrome extension for managing tmux sessions in a persistent sidebar. The licence is MIT.

When your agent uses it

  • Working on Terminal.tsx
  • Xterm.js integration
  • Resize handling
  • Any TabzChrome extension/backend code

Example prompts

  • “Use the tabz-development skill to pattern for building and debugging TabzChrome itself. An agent skill from GGPrompts/TabzChrome”
  • “/tabz-development”

What it can do on your machine

Read from SKILL.md and the folder at commit ec502b1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tabz Development loads about 437 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 60 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~437
With references · SKILL.md plus every file in references/, read only if the agent opens them
~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

TabzChrome Development

Reference patterns for building TabzChrome's terminal implementation.

Quick Patterns

Terminal Initialization
typescript
const term = new Terminal({ /* options */ });
const fitAddon = new FitAddon();
term.loadAddon(fitAddon);
term.open(containerRef.current);
fitAddon.fit();
Resize Handling
typescript
// Debounce resize, sync xterm → PTY
fitAddon.fit();
ws.send(JSON.stringify({ type: 'resize', cols: term.cols, rows: term.rows }));
WebSocket I/O
typescript
// Terminal → Backend
term.onData(data => ws.send(JSON.stringify({ type: 'input', data })));
// Backend → Terminal
ws.onmessage = (e) => term.write(JSON.parse(e.data).data);
