Mjolnir by Brokk

The power
frontend for Codex and Claude.

Choose who codes and who reviews. Keep the workspace and control plane on your machine, drive the session remotely, isolate work in worktrees, speak your prompts, and challenge every change before it lands.

Install Mjolnir

curl -fsSL https://raw.githubusercontent.com/BrokkAi/mjolnir/master/install.sh | bash

brew install brokkai/tap/mjolnir

npm install -g @brokkai/mjolnir

npx -y @brokkai/mjolnir

cargo install --locked brokk-mjolnir brokk-mj-voice-worker

git clone https://github.com/BrokkAi/mjolnir.git && cd mjolnir && cargo build --release

SESSION

CODER/ OWNS THE TURN

Codex or Claude · plans the work · writes the briefs

SUBAGENTS/ IMPLEMENT

fresh sessions · run in parallel

TEAMS / CHOOSE WHO CODES, WHO REVIEWSSWITCH WITH SHIFT+TAB

CODERowns the turn and launches the subagents
REVIEWERchallenges changed turns from an independent session

Run Codex or Claude solo, or split the seats either way. Switching teams keeps the terminal, permissions, sessions, and remote workflow unchanged.

One operating environment

Put Codex or Claude in charge of the turn.

The selected coder plans, edits, runs tools, delegates, and answers. Mjolnir wraps that session in shared project knowledge, self-hosted remote control, a worktree-first workflow, cross-platform voice, and integrated adversarial review.

01 / RUN

The coder owns the turn

Choose Codex or Claude to own the turn, with automatic model selection inside that provider.

agent://coder

02 / CONTROL

Mjolnir runs the workshop

Self-hosted remote access, worktrees, voice, and review policy stay under your control.

host://self

03 / REVIEW

Adversaries challenge the diff

A separate supervisor forms a risk map, calls focused specialist lanes when needed, and vets their findings.

agent://adversary

Why Mjolnir

Your coding team where you are, with stronger controls.

The repository and Mjolnir server stay on your machine. Work from the terminal or a remote browser, dictate prompts locally on desktop, and keep every permission and nested agent attributable.

01 / REMOTE

Mjolnir Web

Drive the same live session from a browser or phone — diffs, permission prompts, new worktree sessions — while the repository stays on your machine.

02 / ISOLATE

Worktrees first

Run the coder in a linked Git worktree so agent changes stay separate and easy to inspect.

03 / SPEAK

Local voice input

Dictate and edit prompts on macOS, Linux, and Windows before sending them to the coder.

04 / CHALLENGE

Adversarial review

Hold delegated changes for an independent, findings-only review before completion.

05 / REMEMBER

Shared project knowledge

Carry verified discoveries between Claude and Codex sessions through one local, inspectable interface.

06 / STEER

Keep the turn on course

Queue a correction while a supported agent is streaming, then use Cancel or Stop to put it into the current turn.

Four teams, one shortcut

Choose who codes. Choose who reviews.

Run Codex, Claude, Codex coder + Claude reviewer, or Claude coder + Codex reviewer. Press Shift+Tab in a session to switch and start the new team. See how teams and adversarial review work.

Run a checked fixture through delegated implementation, pushed-back reports, adversarial review, session resume, and headless output before using Mjolnir on a private repository.
