Configuration

Settings go in init.lua, a Lua script that calls maki.setup(). Same language as plugins.

Two places, both optional:

• Global: ~/.config/maki/init.lua
• Project: .maki/init.lua in the active Git checkout, or in the working directory outside Git

When both exist, project settings override global ones. Neither file is required. A project init.lua runs only once you trust that folder, see Folder Trust.

Example

maki.setup({
    ui = {
        splash_animation = true,
        mouse_scroll_lines = 5,
        theme = "tokyonight",
        tool_output_lines = {
            bash = 8,
            read = 5,
        },
    },
    agent = {
        max_output_lines = 3000,
    },
    provider = {
        default_model = "anthropic/claude-sonnet-4-6",
        allowed_models = { "anthropic/*", "openai/gpt-5" },
        excluded_models = { "*/*-preview" },
    },

    storage = {
        max_log_files = 5,
    },
    plugins = {
        bash = { timeout_secs = 180 },
        index = { max_file_size_mb = 4 },
    },
})

All fields are optional. Typos in field names cause an error right away.

provider.allowed_models is a list of glob patterns for qualified provider/model-id specs. * also matches /, so opencode/* includes nested model IDs. When the list is empty or omitted, every model is allowed. provider.excluded_models removes matching models after that, so exclusions always win. A project list replaces the matching global list; omit it to inherit or use {} to clear it. The policy applies to selectors, CLI and API model changes, delegation, and maki models.

maki.setup() can only be called once per init.lua.

ui.theme

Name of the color theme to load at startup, overriding the theme you last picked interactively. If unset, Maki keeps your last selection (the built-in default on first run). An unknown name is ignored with a warning.

Available themes: ayu_dark, ayu_light, ayu_mirage, carbonfox, catppuccin_frappe, catppuccin_latte, catppuccin_macchiato, catppuccin_mocha, dark_daltonized, dracula, everforest_dark, fleet_dark, github_dark, gruvbox, gruvbox_light, kanagawa, kanagawa_ink, kanagawa_plum, material_darker, monokai_pro, night_owl, nightfox, nord, onedark, rose_pine, rose_pine_dawn, rose_pine_midnight, rose_pine_moon, solarized_dark, solarized_light, tokyonight, vscode_dark_plus, zenburn.

You can add your own themes too. Drop a <name>.toml file into themes/ inside your Maki config directory, for example ~/.config/maki/themes/. If it reuses a built-in name, yours wins.

Diff signs use diff_old_sign and diff_new_sign, which default to diff_old and diff_new. These styles are applied after code_block, so their properties take precedence. Diff gutters use diff_old_line_nr and diff_new_line_nr, which default to diff_line_nr.

Themes use 24-bit colors by default, but not every terminal can show them. Maki checks the environment, terminfo, and the terminal itself, and when truecolor is missing it quietly falls back to the closest of the 256 classic terminal colors. If detection gets it wrong, set MAKI_TRUECOLOR=1 to force truecolor or MAKI_TRUECOLOR=0 to force the fallback.

Theme files can also name terminal colors instead of giving hex values, using the same names as Helix: default, black, red, green, yellow, blue, magenta, cyan, gray, light-red, light-green, light-yellow, light-blue, light-magenta, light-cyan, light-gray, and white. Write them exactly as listed. lightgray, light_gray and LIGHT-GRAY are all rejected. default means the terminal default. Maki also takes a number from 0 to 255 to pick a palette entry by index, which Helix does not.

These work everywhere a hex value does, including syntax highlighting scopes, so a theme can be written entirely against the palette your terminal already defines. Maki passes them through as palette references rather than resolving them to RGB, so the colors stay correct in terminals that mangle truecolor, such as nested tmux over ssh.

allowed_models	string[]	[]	-	Glob patterns for permitted qualified model specs; empty permits all models
excluded_models	string[]	[]	-	Glob patterns for excluded qualified model specs; exclusions take precedence
connect_timeout_secs	u64	10	1	HTTP connect timeout (seconds)

storage

Field	Type	Default	Min	Description
max_log_bytes_mb	u64	200	1	Max total log size (MB)
max_log_files	u32	10	1	Max number of log files to keep
input_history_size	usize	100	10	Number of input history entries to retain

net

Field	Type	Default	Description
allowed_private_hosts	string[]	[]	Hosts allowed to resolve to a private or loopback address, as host, host:port, or a CIDR range. Plain http:// is kept for them instead of being upgraded to https://

maki.net refuses private, loopback and metadata addresses, because the model picks the URLs. List a host here to let it through:

maki.setup({
    net = {
        allowed_private_hosts = { "localhost:8080", "nas.lan", "10.0.0.0/8" },
    },
})

An entry with no port covers every port. A name you list is allowed whatever it resolves to. A name you did not list stays blocked when DNS lands it on a private address, unless that address falls in a range you allowed, so keep ranges as small as the service needs. Every redirect hop is checked against the same list. Permissions covers what the guard protects.

trust

Answers the folder trust question in advance. Read from the global ~/.config/maki/init.lua only, since a project file that could set it would be trusting itself:

maki.setup({
    trust = {
        paths = { "~/src/me/*", "/workspace" },
        prompt = false,
    },
})

paths is a list of globs matched against the project root, empty by default. prompt is a bool, true by default. Setting it to false drops the startup card and leaves the folder restricted unless a paths entry matches. Folder Trust covers glob syntax and which run modes apply the policy.

Every field also has an environment variable, shown in the Env column, and the variable wins. See Telemetry for the full picture.

Plugins

The plugins table turns plugins on or off and passes options to them. All bundled plugins are on by default. Set enabled = false to turn one off.

A plugin that is off never loads, so its tool name is free for one of your own plugins to take. Permission rules are keyed by the tool name alone, and names such as bash, write, and task already have rules in maki. A plugin that takes one of them inherits those rules, together with any "always allow" you saved. Maki warns you at load when this happens.

Each plugin checks its own options at startup. A typo, a wrong type, or an unknown plugin name gives you a clear error right away.

The edit plugin's extra tools are options too: plugins.edit = { multiedit = false, insert_lines = true }. The old tools table is gone. If your config still uses it, Maki stops at startup and shows you the new form.

This table is for bundled plugins only. Your own plugins go in ~/.config/maki/lua/, see Plugins.

maki.setup({
    plugins = {
        bash = { timeout_secs = 180 },
        websearch = { enabled = false },
    },
})

Validation

If a value is below its minimum, Maki shows a ConfigError with the field name, value, and minimum.

Directory layout

Maki follows platform directory conventions. On Linux and macOS that is XDG. On Windows, config, data, state, and logs all live under Roaming AppData (Windows has no separate state dir in this layout).

Purpose	Linux / macOS	Windows
Config	~/.config/maki/	%APPDATA%\maki\
Data	~/.local/share/maki/	%APPDATA%\maki\
State	~/.local/state/maki/	%APPDATA%\maki\
Logs	~/.local/logs/maki/	%APPDATA%\maki\
Cache	~/.cache/maki/	%LOCALAPPDATA%\maki\

Config holds init.lua, permissions.toml, mcp.toml, providers.toml, and commands/. State holds sessions, auth tokens, memories, plans, folder trust, and model-tier overrides. The install script puts the binary under %LOCALAPPDATA%\maki on Windows; that is separate from these runtime dirs.

~/.maki/ (or %USERPROFILE%\.maki\) is checked as a legacy fallback. If that directory still exists, maki uses it for everything until you migrate.

Migrating from ~/.maki/

maki migrate xdg

This safely moves sessions, auth, plans, memories, logs, and preferences to the platform locations above. Where both old and new files exist, they are merged (input history, model tiers, etc.). Nothing is deleted until it has been copied. At the end you get a summary of where everything lives now.

Safe to run more than once.

Personal Instructions

On top of the project instruction files Maki loads from the git root down to the cwd (AGENTS.md, CLAUDE.md, and friends; see Context), you can add:

• AGENTS.local.md in any of those project directories for per-directory preferences (gitignored)
• ~/.config/maki/AGENTS.md for preferences that apply to all projects

All of these are added to the system prompt at the start of every session.

Memory

The memory tool and /memory command store small Markdown notes under the state directory, scoped per project:

…/state/maki/projects/<project-id>/memories/

(Linux/macOS: ~/.local/state/maki/…; Windows: %APPDATA%\maki\…). Use them for non-obvious gotchas and decisions that should survive across sessions. They are separate from skills and from AGENTS.md.
