root-result-cap

Off by default: once a workspace turns it on, it reports one tool result too large for a main thread's context, said on its next call.

What it catches

One tool result too large for a main thread's context, said on its next call.

Why

A tool result stays in the context every later call re-sends. The main transcript is read after each call for the results it gained, and one past the level's size is said on the next call: once a session at light, once per tool at standard and strict, with lower sizes at each. It never refuses, since the result has already arrived. A chars parameter replaces the level's size.

Default and override

By default this rule takes the decision off. A workspace sets it by name, in its root magusfile, to advise or off:

magus\guard.builtins({"root-result-cap": "advise"})

A loosening takes effect once it is committed; a tightening applies at once.

Seeing it

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

advise [root-result-cap]: ...

magus describe rule root-result-cap 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.

Magusfile

The magusfile.buzz that declares a project's targets (as export funs) and binds its spells. Magusfile in full.

Buzz

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

Tool

An action a model can call through its host: a name, a description, a typed input and a result. magus serves its tools over MCP, each a read of the workspace model or a run of the CLI it already has. Tool 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.
