magus-status

Inspect concurrency pool and configuration

Synopsis

magus status [flags]

Description

Show the magus configuration that affects this process - telemetry, cache settings - and, when a parent magus process is running, the live state of its concurrency pool (current slot usage, queued waiters).

When --watch is non-zero, status polls and reprints at that interval. On a TTY the screen is cleared between reprints; piped output appends each snapshot on its own line for log capture.

--wait prints no snapshot: it exits 0 once this machine's build budget can seat a run, and it is how a run refused with MGS3009 waits without a retry loop. Piped into a magus run (magus status --wait | magus run test .) it reads that run's command from the pipe, waits until the budget can seat the claims that run will make, and holds the run from starting until it exits; the run then proceeds as usual, or starts nothing (MGS3030) if the wait failed. On its own it waits for a free slot. A claim larger than the whole budget exits 78 at once; no broker means nothing to wait for, and it exits 0.

Options

-W duration
Short for --watch
-c
Short for --compact
--compact
Single-line, densely-packed snapshot for sidebar/multiplexer use (text output only)
--probe string
Exec-probe mode: liveness or readiness (exit 0 healthy, 1 unhealthy; ignores --watch/--compact)
--socket string
Proc server to report on, as a unix:// URL or bare path; default: MAGUS_PROC_SOCKET inside a run, else every live one in the socket dir. --probe asks the server at server.address unless this names one
--symbols
Include the expensive symbol-index freshness scan
--wait
Exit 0 once the build budget can seat the magus run reading this pipe (a free slot when none does); holds that run until then, then reserves the seat for it until its first claim
--watch duration
Poll and reprint at this interval (minimum 15s; 0 means one-shot)
--workspace string
Workspace root to check for readiness with --probe=readiness (default: any loaded workspace)

Examples

One-shot status snapshot

magus status

Run tests once the build budget can seat them

magus status --wait | magus run test .

Live updates every 15 seconds

magus status --watch=15s

Single-line snapshot for a multiplexer sidebar

magus status --compact --watch=15s

Inspect a specific running parent

magus status --socket=unix:///run/user/1000/magus/server.sock

Glossary

Workspace

The magus root directory that owns a set of projects and shared config; the unit magus operates over. Workspace in full.

Op

A single tool-native command a target composes (long form: operation); the middle of the work hierarchy (Spell to Op to Target). Op in full.

Spell

A language/runtime adapter (e.g. go, md) that maps generic targets onto a toolchain's real commands. Spell in full.

Buzz

The language magusfiles are written in (the .buzz engine). Buzz in full.

Cache

The content-addressed store magus consults before running a target, so unchanged work is skipped. Cache in full.

Affected

The set of projects touched by a change; magus affected <target> runs a target only over them. Affected in full.

Broker

The per-user background process that holds this host's capacity: the machine budget every run claims slots from, and the shared services runs keep warm. A run starts it on demand; broker: off in magus.yaml runs without one. Broker in full.

CI

An ordinary target you compose yourself with ctx.needs; magus does not hardcode its stages. It is the anchor magus affected ci keys off, and ci strips the rw charm. CI in full.

Pool

The concurrency pool: the shared set of slots that caps how many targets run in parallel on one machine. Its capacity defaults to MAGUS_CONCURRENCY, then 4 on GitHub-hosted runners, then min(NumCPU, 8); magus status and the dashboard report it live. Pool in full.

Slot

One unit of the pool's capacity. A target acquires the slots it needs to run (most take one) and releases them when it finishes; the pool tracks capacity (total slots), running (acquired), and queued (blocked). Slot in full.

Concurrency

How many targets run at once. It is bounded by the pool's capacity and set with --concurrency, MAGUS_CONCURRENCY, or the concurrency config key. Concurrency in full.

Queued

A target that wants a slot while the pool is full; it blocks first-in-first-out until a slot frees. The dashboard colors a sample with queued > 0 accordingly. Queued in full.

Snapshot

A point-in-time view of live state (the pool's occupancy or a tick of exported metrics), as opposed to accumulated history. Snapshot in full.

Health

The at-a-glance daemon state derived from the pool: healthy when the pool is reporting, degraded when it reports an error, down when there is no pool. The dashboard color-codes each state. Health in full.

MAGUS.md

The committed routing index at a workspace root, regenerated from the knowledge graph: it lists every node and points at the exact query for a given question, so it is the entry point an agent reads first. MAGUS.md in full.

Agent

A model working through an agent host such as Claude Code, Codex, Cursor or OpenCode. magus treats an agent as one more caller of its CLI, MCP tools and console, held to the same checks as a person. Agent in full.

Session

An agent host's conversation, by the id the host delivers to its hooks. magus never mints one: a record with no session is unattributed, and the OS user it carries says whose account ran it. Session in full.

Job

The unit of delegated work, and one row of the job store: what an orchestrating agent handed out, with its goal, the checkpoint it was cut against, the paths it may write or must not touch, and the one check it runs. A job's holder is either a session, for work an orchestrator handed out, or the daemon, for its own maintenance. The store records; the agent guard is what reads those facts back when grading a write. Job in full.

Run

One target executing under one magus invocation, such as magus run test web or magus affected ci. A run keeps its captured output behind an output reference. Every magus run is a run whether or not any job asked for it; see Job for how the two relate. Run in full.
