What is tabz-development?

Development guidance for TabzChrome’s terminal and extension code, including its React terminal component, xterm.js display, WebSocket communication, and backend process handling.

Useful for changing terminal initialization, handling resize events, managing terminal sessions, debugging WebSocket input and output, and working on the terminal backend.

It helps developers trace how terminal input, output, sessions, resizing, and backend processes work together when fixing TabzChrome itself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.00404
Opus 5.5	$0.00018	$0.00162
Sonnet 5.5	$0.00009	$0.00081
Haiku 4.5	$0.00004	$0.00040

Measured 2mo ago against content hash dea486797deb, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

tabz-development scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

TabzChrome Development

Reference patterns for building TabzChrome's terminal implementation.

Core Architecture

extension/components/Terminal.tsx  →  WebSocket  →  backend/modules/pty-handler.js
         ↓                                                    ↓
    xterm.js render                                      tmux session

Key Files

File	Purpose
`extension/components/Terminal.tsx`	xterm.js terminal + resize
`extension/hooks/useTerminalSessions.ts`	Session lifecycle
`extension/background/websocket.ts`	WebSocket management
`backend/modules/pty-handler.js`	PTY spawning, tmux

Quick Patterns

Terminal Initialization

const term = new Terminal({ /* options */ });
const fitAddon = new FitAddon();
term.loadAddon(fitAddon);
term.open(containerRef.current);
fitAddon.fit();

Resize Handling

// Debounce resize, sync xterm → PTY
fitAddon.fit();
ws.send(JSON.stringify({ type: 'resize', cols: term.cols, rows: term.rows }));

WebSocket I/O

// Terminal → Backend
term.onData(data => ws.send(JSON.stringify({ type: 'input', data })));
// Backend → Terminal
ws.onmessage = (e) => term.write(JSON.parse(e.data).data);

References

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tabz-development is a skill published in the GitHub repository GGPrompts/TabzChrome (149 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 404 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
