workspace-spawn-failed

An advisory by default: it explains, and blocks nothing, on a spawn the workspace's rule could not judge, so only the built-in rules graded it.

What it catches

A spawn the workspace's rule could not judge, so only the built-in rules graded it.

Why

A workspace spawn rule that fails to load or errors judges nothing, and a spawn or continuation reaching a verdict without it must say so rather than read as fully judged. The first notice in a session names each failing side and its error; a repeat is one line naming what applied. It stands alone only when the built-in rules passed the call; on any other verdict the note is appended to that verdict. A workspace cannot set it: magus\guard.builtins refuses the name, since the notice is how the workspace learns its own rule judged nothing.

Default and override

This rule always takes the decision advise. A workspace cannot set it: naming it in magus\guard.builtins fails to load, because the rule is how a workspace learns that a rule of its own judged nothing.

Seeing it

A verdict names its rule in brackets, which is how you got here:

advise [workspace-spawn-failed]: ...

magus describe rule workspace-spawn-failed prints the same entry at a terminal, and magus describe rules lists every rule this workspace enforces.

Glossary

Workspace

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

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.

Advisor

One read-only check from the advice suite: it reads the changeset through magus and writes one titled section of findings. The same advisors run as a pull request comment in CI and inside magus diff --impact locally. Advisor in full.
