Capabilities
Features
Everything you need to govern, test, and observe your AI coding agents — running entirely on localhost.
01 · The guard
Manage & test hooks
before agents run them
The core of Argus: one-click hook presets, a structured config editor, and a simulator that fires synthetic payloads at any hook command — plus a free public collection of battle-tested guardrail scripts.
- ▸ One-click presets for Claude Code, Codex, and 9 more agents — tagged, additive, reversible
- ▸ Simulator runs any hook against a realistic payload for every event type
- ▸ Inspect stdout, stderr, exit code, and duration without a live agent
- ▸ Public script collection: command blocker, secrets guard, branch protection, auto-format, injection scanner
- ▸ Structured JSON editor with live validation
02 · The armory
A community registry
of battle-tested guardrails
Zero-dependency hook scripts, free for everyone — browse and one-click install from the community registry, test in the simulator first, then publish your own with an optional GitHub login. The bundled guardrail scripts target Claude Code and Codex.
- ▸ Browse and search the whole community registry from the Scripts page
- ▸ One-click install any script into ~/.argus/hooks
- ▸ Publish your own via a pull request, or back up your collection to a private gist
- ▸ block-dangerous, protect-secrets, protect-branch, format-lint, scan-injection, and more
- ▸ Nothing is uploaded except the scripts you choose to share
03 · The record
Every tool call,
in real time
Argus streams every agent action to your browser the instant it fires. No polling. No refresh.
- ▸ SSE stream — events appear the moment a hook fires
- ▸ Normalized event model across every supported agent
- ▸ Filter the session list by agent or project, plus free-text search
- ▸ Expand any event to inspect the raw payload
04 · The ledger
Every session,
in one list
Sessions stream into one list, newest first, filterable by agent and project. Click a session for its full chronological event stream.
- ▸ Session id, agent, project, and last-activity time
- ▸ Filter by agent or project; free-text search
- ▸ Load more as you scroll
- ▸ Open a session for its full event stream
- ▸ Expand any event for the raw payload — diffs, commands, output
05 · The pulse
The instrument
checks itself
Diagnostics shows the watcher is awake: health, storage, hook inventory, and live log tails.
- ▸ Readiness and per-agent connectivity status
- ▸ SQLite size, journal mode, and WAL
- ▸ Active hook preset detection (Baseline / Medium / Full)
- ▸ ~/.argus file inventory with reveal-in-Finder
- ▸ argus and hook-script log tails
