daemon

A command for managing the local background service and browser connection used by the Side Panel.

In plain words
What is it for?
Use it to install or upgrade the service, configure its port and token, and register the Chrome browser bridge when needed.
Why use it?
It handles startup, local-only access, authentication, and browser pairing across macOS, Linux, and Windows.

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.

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.

Security

Grade A, and why

daemon 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 yesterday.

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.

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

summarize daemon

summarize daemon <subcommand> [options]

Manages the local HTTP daemon and its browser integration. The daemon binds to 127.0.0.1 only and requires a shared bearer token. Chrome reaches it through an optional exact-ID Native Messaging host; Firefox retains its existing loopback integration. The daemon autostarts via the right service manager for your platform.

Platform Service
macOS LaunchAgent (launchd)
Linux systemd user service
Windows Scheduled Task

If you only use the CLI, you don't need any of this.

Subcommands

install

Install or upgrade the autostart service, write ~/.summarize/daemon.json, and register Chrome native host com.steipete.summarize on macOS/Linux.

summarize daemon install --token <TOKEN>
summarize daemon install --token <TOKEN> --port 8787
summarize daemon install --token <TOKEN> --dev --extension-id <UNPACKED_ID>

--token <token> is required on first install; the extension prints one after pairing. Re-running install with a new token adds another paired browser instead of invalidating the old one. The native host manifest allows only Chrome Web Store extension ID cejgnmmhbbpdmjnfppjdfkocebngehfg.

restart

Restart the autostart service. Useful after upgrading summarize or editing daemon.json.

summarize daemon restart

status

Probe the autostart service, Chrome native-host registration, and the running daemon's health endpoint.

summarize daemon status

uninstall

Unload the autostart service and remove the user-level Chrome native host. On macOS the daemon plist is moved to Trash so you can undo.

summarize daemon uninstall

run

Run the daemon in the foreground. The autostart entry uses this internally; use it directly inside containers, on systems without launchd/systemd, or while debugging.

summarize daemon run --port 8787

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.

daemon is a command published in the GitHub repository steipete/summarize (6,586 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,029 tokens. 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.
