mb-todo 0.0.6

CLI-first todo manager with local SQLite storage

mb-todo

CLI-first todo manager. Data stored locally in SQLite. All GUIs (Raycast extension, etc.) interact through CLI commands with --json flag — CLI is the single source of truth.

Data Model

Project

Field	Type	Description
name	TEXT NOT NULL PRIMARY KEY	Project name

Todo

Field	Type	Nullable	Description
id	INTEGER PRIMARY KEY AUTOINCREMENT	NO	Short numeric ID for CLI ergonomics
title	TEXT NOT NULL	NO	Todo title
body	TEXT	YES	Extended description
closed	INTEGER NOT NULL DEFAULT 0 CHECK (closed IN (0, 1))	NO	0 = open, 1 = closed
priority	TEXT NOT NULL DEFAULT 'medium' CHECK (priority IN ('low','medium','high'))	NO	Priority level
project	TEXT REFERENCES projects(name) ON UPDATE CASCADE ON DELETE RESTRICT	YES	Project name (direct FK)
tags	TEXT NOT NULL DEFAULT '[]'	NO	JSON array of tag strings
created_at	INTEGER NOT NULL	NO	Unix timestamp
closed_at	INTEGER	YES	Unix timestamp, set on close
updated_at	INTEGER NOT NULL	NO	Unix timestamp, set to created_at on insert

Indices

CREATE INDEX idx_todos_closed ON todos(closed);
CREATE INDEX idx_todos_project ON todos(project) WHERE project IS NOT NULL;

Design Decisions

• Integer IDs — CLI ergonomics (mb-todo close 42)
• Projects as name-only table — a project is just a label picked from a list; no metadata needed
• Text FK for project — eliminates JOINs, project name stored directly in todos
• RESTRICT on project delete — prevents orphaning; user must reassign todos first
• CASCADE on project rename — transparent propagation
• Tags as JSON array — simpler schema, queryable via json_each(), no junction table needed
• updated_at NOT NULL — set to created_at on insert, refreshed on update; "never modified" = updated_at == created_at
• closed_at nullable — set when closing, enables "done today/this week" queries
• Priority defaults to medium
• Timestamps as unix seconds
• SQLite STRICT mode
• No due_date — deferred; can add via migration later if needed

CLI

Global Flags

Flag	Short	Description
--json		JSON output
--data-dir PATH		Data directory (env: MB_TODO_DATA_DIR, default: ~/.local/mb-todo/)
--version		Print version and exit

Todo Commands

mb-todo add <title>

Create a new todo.

Option	Short	Type	Description
--body		TEXT	Extended description
--priority	-P	low|medium|high	Priority level (default: medium)
--project	-p	TEXT	Assign to project
--tag	-t	TEXT (multiple)	Add tags (repeatable)

mb-todo list

List todos. By default shows only open todos, sorted by updated_at (newest first).

Option	Short	Type	Description
--closed		FLAG	Show only closed todos
--all	-a	FLAG	Show all todos (open + closed)
--project	-p	TEXT	Filter by project
--priority	-P	low|medium|high	Filter by priority
--tag	-t	TEXT	Filter by tag
--sort	-s	created|priority|updated	Sort order (default: updated)
--limit	-n	INT	Max number of results

mb-todo show <id>

Show a single todo with all fields.

mb-todo edit <id>

Edit a todo. At least one option is required.

Option	Short	Type	Description
--title		TEXT	New title
--body		TEXT	New body
--priority	-P	low|medium|high	New priority
--project	-p	TEXT	New project (empty string to unset)
--tag	-t	TEXT (multiple)	Replace all tags (repeatable)
--add-tag		TEXT (multiple)	Add tags (repeatable)
--remove-tag		TEXT (multiple)	Remove tags (repeatable)

Errors: NO_CHANGES if no options provided, TAG_CONFLICT if --tag used with --add-tag/--remove-tag.

mb-todo close <id>...

Close one or more todos. Sets closed = 1 and closed_at to current timestamp. Multiple IDs are processed best-effort.

mb-todo reopen <id>...

Reopen one or more closed todos. Sets closed = 0 and closed_at to null. Multiple IDs are processed best-effort.

mb-todo delete <id>...

Permanently delete one or more todos. Asks for confirmation before deleting (interactive mode only). Multiple IDs are processed best-effort.

Option	Short	Type	Description
--yes	-y	FLAG	Skip confirmation prompt

Project Commands

Subgroup: mb-todo project <command>

mb-todo project list

List all projects.

mb-todo project add <name>

Create a new project. Error: PROJECT_EXISTS if name is taken.

mb-todo project rename <old> <new>

Rename a project. All todos referencing the old name are updated automatically (CASCADE). Error: PROJECT_EXISTS if new name is taken.

mb-todo project delete <name>

Delete a project. Error: PROJECT_HAS_TODOS if any todos reference the project.

JSON Envelope

All --json output uses a consistent envelope (matches mb-pomodoro):

{"ok": true, "data": {...}}
{"ok": false, "error": "CODE", "message": "..."}

Error Codes

Code	Description
TODO_NOT_FOUND	Todo ID does not exist
ALREADY_CLOSED	Todo is already closed
ALREADY_OPEN	Todo is already open
PROJECT_NOT_FOUND	Project name does not exist
AMBIGUOUS_PROJECT	Partial project name matches multiple projects
PROJECT_EXISTS	Project name already taken
PROJECT_HAS_TODOS	Cannot delete project with assigned todos
INVALID_PRIORITY	Priority value not in (low, medium, high)
NO_CHANGES	edit called with no options
TAG_CONFLICT	--tag used together with --add-tag/--remove-tag
VALIDATION_ERROR	General input validation failure
