Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00766 | $0.00766 |
| Opus 5 | $0.00383 | $0.00383 |
| Sonnet 5 | $0.00153 | $0.00153 |
| Haiku 4.5 | $0.00077 | $0.00077 |
Grade A, and why
claude-command-center copilot-instructions.md scanned grade A with 1 finding 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 3d 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.

Copilot Instructions - Claude Command Center
Project Overview
Claude Command Center is a multi-session Claude Code terminal orchestrator built with Electron 33, React 18, TypeScript, and Tailwind CSS v4. It manages multiple Claude Code CLI sessions in parallel, with features like SSH remoting, vision/browser control, cloud agents, tokenomics tracking, and a memory visualizer.
Tech Stack
- Runtime: Electron 33 (main + renderer + preload)
- UI: React 18 with Zustand 5 for state management
- Styling: Tailwind CSS v4 with
@themedirective insrc/renderer/styles.css(no tailwind.config) - Terminal: xterm.js 5.5 with WebGL addon, node-pty for PTY management
- Build: electron-vite, electron-builder for packaging
- Testing: Vitest (unit), Playwright (E2E)
- Color palette: Catppuccin Mocha - use theme tokens (base, mantle, crust, surface0-2, overlay0-2, subtext0-1, text, blue, green, red, yellow, peach, mauve, teal, etc.)
Architecture Rules
- All renderer↔main communication goes through IPC channels defined in
src/shared/ipc-channels.ts - Never import Node.js modules (fs, path, os, child_process) in renderer code - use the preload bridge
- IPC handlers live in
src/main/ipc/with one file per domain - Config is persisted as JSON files via
src/main/config-manager.ts - Stores are in
src/renderer/stores/using Zustand - hydrated from config on startup
Coding Style
- Use named exports. Default exports only for React components that are the sole export of their file
- Prefer
constoverlet. Novar - Use TypeScript strict mode patterns - avoid
anywhere possible - Keep components focused - if a file exceeds ~400 lines, consider splitting
- Use Catppuccin color tokens in Tailwind classes, not raw hex values
- Inline SVG icons - no icon library dependencies
Common Gotchas
- esbuild (used by electron-vite) does not support
\u{...}Unicode escapes in JSX - useString.fromCodePoint()or inline SVGs instead - PTY write chunking: only chunk large writes (>256 bytes, 12ms delay). Never queue all PTY writes - this was tried in v1.2.113 and caused severe input lag
- xterm.js scrollback must stay at 10000 max - higher values cause ~1GB RAM per terminal
- Modal backdrop clicks: never put
onClick={onCancel}on backdrop divs because Ctrl+C triggers click events - SSH sessions use base64-encoded setup scripts - comments in the script body break single-lining
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.

claude-command-center copilot-instructions.md is an instructions file published in the GitHub repository nubbymong/claude-command-center (42 stars, last pushed 3d ago), licensed MIT. It adds 766 tokens to every session, about $0.0038 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
