buzz-unbriefed

A deny rule by default: it refuses the first Buzz a session authors, by file write or magus buzz -e, before reading the Buzz skill, and names what to run instead.

What it catches

The first Buzz a session authors, by file write or magus buzz -e, before reading the Buzz skill.

Why

Buzz is in no model's training data, so what gets written is Go or TypeScript with the serial numbers filed off, and enough of it parses to reach review. Typical errors of an agent with this repository open throughout: fs\glob indexed as strings when it returns [Path]; .append on a list declared without mut; the ternary form, which upstream-strict parsing rejects outside --embedded; archive\extract, which does not exist; a missing import "fs"; and .sub sliced by character on BYTE-indexed strings. Reading first supplies every one of them. It grades the session, not the file: one Skill(magus-buzz-lang) and every later Buzz write passes. Reads are never gated, since reading is how the language gets learned, so magus buzz <file> and magus buzz -t <file> run something that already exists and go untouched.

Default and override

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

magus\guard.builtins({"buzz-unbriefed": "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:

deny [buzz-unbriefed]: ...

A workspace that sets this rule to advise sees advise [buzz-unbriefed]: ... instead.

magus describe rule buzz-unbriefed 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.

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.

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.

Skill

A packaged set of instructions an agent host loads when a task matches its description: a directory holding a SKILL.md. magus ships its magus-* skills in the binary and writes them with magus agent install. Skill 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.

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.

Conventions

Placeholders

Angle brackets mark a value you replace with your own; never type the brackets:

magus run <target>
magus completion <shell>    # e.g. bash, zsh, fish

<target>, <path>, <shell>, <name> and the like are stand-ins, not literal text.
