At a glance

• Activity in your notch. A breathing glow follows agent activity. Expand the panel to see quotas, token usage, and active sessions. Every display gets its own HUD — a screen without a notch shows the watched agents' logos in a row instead of a bar pretending to have one.
• Answers without a detour. When a client stops to ask whether a tool may run, the request arrives on the HUD. Hover to read what it wants — the file, the command, the lines it would change — and allow or deny it there. Saying nothing is always available: the client keeps waiting on its own prompt in the terminal, exactly as if the HUD were closed.
• Usage in context. Track reset times, quota trends, model usage, and available API balances in one statistics window.
• Make it yours. Choose visible agents, glow appearance (a soft blur or a halftone, ASCII, block, Braille or binary grid, each with breathe, flow, scan, ripple, shimmer and boot effects), language, and startup preferences. Usage alert levels are fixed at 70% / 90% used.

Press ⌘⌥H to toggle the glow. The menu bar gives you quick access to usage and settings.

Quick start

Requirements: macOS 14 or later, plus Xcode or the Xcode Command Line Tools with a Swift 6 toolchain.

git clone https://github.com/jazzenchen/agent-hud-open.git
cd agent-hud-open
make check
make test
make run

This builds and opens build/Agent HUD Open.app. The app is signed ad-hoc for local use; no developer account, signing identity, or provisioning profile is required.

Supported clients

Claude Code · Codex Desktop / CLI · DeepSeek Harness · Antigravity · Cursor · Grok CLI · GitHub Copilot CLI · OpenCode · Kimi · GLM · Pi · OpenClaw · Hermes Agent · ZCode · CodeBuddy · WorkBuddy · Qwen Code

Install and sign into the clients you want to monitor. Available activity, quota, and balance information depends on the client and account. See session lifecycle coverage for support for running and terminal turns.

Permission requests can be answered from the HUD for the clients whose own hook runs just before they ask: Claude Code, Codex, CodeBuddy, WorkBuddy, ZCode, Qwen Code and the Qoder builds. See approvals.

Data access

No Agent HUD account is required. The app reads local agent activity and queries the corresponding providers for usage or balances where supported, using the installed clients' existing sign-in or configured credentials.

See data access for provider details, credential boundaries, and local storage.

Development

Continuous integration checks source boundaries, runs unit tests, builds the application, and verifies its signature and bundled resources. It does not publish binaries.

Modules

The libraries can also be consumed through Swift Package Manager. DesktopApplication(options:settings:store:additionalSettingsPages:onIslandEvents:) takes a SettingsStore and UsageStore plus optional host settings pages and an alert relay, and showSettings(pageID:) opens one of those pages; the host owns any additional services. See architecture.

Documentation

• Architecture — modules, host integration, storage, design invariants, and versioning.
• The HUD on screen — per-display placement, the logo queue, the glow, hovering, events, and approvals.
• Data access — provider queries, credentials, and local storage.
• Usage semantics — token dimensions, percentages, alert levels, request intervals, and reading retention.
• Providers — per-client data sources, credentials, endpoints, counting, billing pools, caches, tests, and upstream references.
• Session lifecycle — running and terminal turn evidence, live status, the Pi observer, and completion hooks.
• Command line — launch options, read-only probes, adapter commands, and environment variables.
• Brand assets — bundled client logos, their sources, rendering, and licenses.
• Roadmap — what is in progress, next, and later.
• Changelog — released versions and host-visible API changes.
