maka

What Maka is

An agent harness exists to finish tasks. We hold it to one measure: how many it completes and at what cost. We publish every run: same model, same official verifier, full per-task record.

• Measured, not claimed. Maka is benchmarked against other harnesses on the same model with the official verifier, and the per-task results ship with every report in docs/eval/.
• The log is the runtime. Every model message, tool call, permission decision and termination is an append-only RuntimeEvent. The UI, the next prompt and crash recovery are projections of that log, never the only copy. Old tool output can leave the next prompt without leaving the log.
• Your machine, your model. Sessions, settings and run records stay local. You bring the model: a cloud API, a local model or a compatible gateway.
• One Runtime Host. Desktop, the TUI and CLI, and Eval are thin clients of one execution authority; Eval owns only the experiment and its scores.

The website walks through one turn of the log and links the published runs. ARCHITECTURE.md has the system map.

Get Maka

Apache Releases: Maka has not made an Apache release yet. When one exists, the signed source archive will be the official release; packages distributed elsewhere are convenience artifacts. See the downloads page and .github/ASF_SOURCE_RELEASE.md for candidate criteria, signing procedures, and verification steps.

Development testing: To contribute or help test unreleased changes, see CONTRIBUTING and the development mailing list. Development builds are not approved Apache releases.

Build from source: To compile and run Desktop, the TUI, or the CLI directly from a source checkout, see the Build from source section below.

Build from source

Requirements

• Node.js 22.19 or newer (CI uses Node.js 24);
• npm (the lockfile and scripts use npm; the current packageManager is npm 11);
• Git;
• ripgrep, used by Runtime's Grep tool.

Start Desktop

git clone https://github.com/apache/maka.git
cd maka
npm ci
npm run dev

npm run dev starts the Desktop development environment with HMR. To build every workspace before starting Electron, use:

npm run dev:full

Direct Peer and Peer Mesh development additionally requires Rust stable 1.98 or newer and the platform linker (Xcode Command Line Tools on macOS, MSVC Build Tools on Windows). Use the peer-enabled entry point so the native addon is built before Desktop starts:

npm run dev:peer       # HMR
npm run dev:full:peer  # full build

If dependencies were installed with ELECTRON_SKIP_BINARY_DOWNLOAD=1, install the Electron platform binary before starting:

node node_modules/electron/install.js

First run

Maka does not bundle a shared model account. On first launch:

1. Open Settings → Models;
2. Add an API, local-model, or supported account connection;
3. Test it and choose a default model;
4. Return to the workspace and start a task.

The app distinguishes configured, send-ready, and experimental connection states. An account flow that is not wired into Runtime is not presented as a usable model.

Terminal entry points

For the public npm package, see the CLI installation and usage guide. The commands below run the development CLI from a source checkout.

Build the workspaces first:

npm run build

Then start the TUI or run one Turn:

npm run cli:dev
npm run cli:dev -- run "Summarize this repository and identify its most important risk"
npm run cli:dev -- run --graph "Implement two independent slices, integrate them, then review the result"
npm run cli:dev -- --help

The TUI also accepts /graph on, /graph off, and /graph <task>. Non-interactive --graph runs wait for the durable Graph to finish before printing the final supervisor output. Graph implementation operators use isolated Git worktrees, so the source project must be a clean Git worktree.

The repository CLI uses the same Maka Dev profile as a development Desktop build. The released maka binary continues to use the Maka profile; the two profiles are not copied or synchronized automatically. Evaluation specs and adapters live in packages/eval.

Architecture

The backend spine is:

Desktop / TUI / CLI → Runtime Host → SessionManager → AgentRun
                                             ↓
                         Model + Tool Runtime → Runtime Event Log
                                             ↓
                              Context / Session / UI projections

Experiment → Cells → Attempts → Results
                    ↓
       Runtime Host executes Maka subjects

Start with ARCHITECTURE.md. It provides the system map, code boundaries, problem-oriented reading paths, and links to the deep dives under docs/architecture/.

Local data and recovery

Workspace data lives under Electron userData by default:

<Electron userData>/workspaces/default/
  runtime.sqlite
  settings.json                  # UI and workspace preferences
  connection-catalog.json        # provider and model metadata
  credential-vault.json          # local provider secrets
  artifacts/

• When editing settings.json or mcp.json by hand, save the file as UTF-8 (preferably without a BOM). A UTF-8 BOM is accepted. Maka does not guess other encodings for files without a BOM or automatically convert UTF-16; explicitly convert those files to UTF-8 in your editor before using them.
• API keys and similar secrets are a local plaintext file (credential-vault.json), readable only by your OS account. The renderer never sees them.
• Tools that write files or run a shell must pass the sandbox boundary first.
• runtime.sqlite is the live record. Older JSONL transcripts and Electron safeStorage credential files are not imported; an upgraded workspace can show empty threads, and those credentials must be entered again.
• Explicit interrupted-turn resume is available by default in Desktop and through CLI/TUI /resume; a successful continuation calls the model and uses tokens. Set MAKA_RUNTIME_SAFE_BOUNDARY_RESUME=0 to disable new re
