todo-processing

This skill describes how to work with todo files located in the configured todos directory (default: docs/agent-todos/). These files track tasks for AI agents working on this project.

Invocation

Step 1: Identify the Todo to Process

If a todo file path is provided as argument:

Use that file directly. Proceed to Step 2.

If no argument is given:

1. Read the configured todos directory from .agent-todos.local.json (todosRoot), defaulting to docs/agent-todos. Look for this file in the project root. If not found there (e.g., when running inside a git worktree), run git rev-parse --git-common-dir to locate the main worktree's .git directory, then check for the config in its parent folder.

2. Find all open todos (non-DONE_, non-TODO_OVERVIEW.md .md files):

   find <todos-dir> -name "*.md" ! -name "DONE_*" ! -name "TODO_OVERVIEW.md" -type f | sort
   

3. If no open todos exist: Ask the user with AskUserQuestion whether they want to create a new todo. If yes, invoke the todo-creation skill via the Skill tool.

4. If more than 5 open todos exist: First ask the user to pick a category using AskUserQuestion. List only subdirectory names that contain at least one open todo as the options.

5. Present the list: Ask the user to select a todo using AskUserQuestion. Show the filename (without full path) as each option label. Use multiSelect: false.

Step 2: Validate and Normalize the Todo File

Missing numeric prefix:

If the selected or given filename does not start with 4 digits (NNNN_):

1. Scan all files in the same category directory (including DONE_ files) to find the highest numeric prefix.
2. Assign the next 4-digit prefix.
3. Rename the file using Bash mv.

Missing or incomplete frontmatter:

If the file has no YAML frontmatter (no --- block at the top), or if title or status fields are absent:

1. Derive the title from the filename:
   • Strip DONE_ prefix if present
   • Strip the numeric prefix (e.g. 0001_)
   • Replace hyphens and underscores with spaces
   • Capitalize the first letter
2. Prepend or patch the frontmatter block with title and status: new.

Step 3: Process the Todo

Directory Structure

Todo files are organized in category subdirectories. Categories are flexible and can be created as needed.

The todos directory is configurable via .agent-todos.local.json (default: docs/agent-todos/).

<todos-directory>/
├── [category]/     # e.g., data, menu, misc, tags, thai-food-dict
│   ├── 0001_task-description.md
│   ├── DONE_0002_completed-task.md
│   └── ...
└── [another-category]/

File Naming Conventions

Open Tasks

• [4-digit-number]_[description].md - e.g., 0001_create-new-feature.md
• TODO-[DESCRIPTION].md - alternative format for quick todos

Completed Tasks

• DONE_[original-filename].md - Add DONE_ prefix when task is complete
• Example: 0001_create-feature.md → DONE_0001_create-feature.md

Supporting Files

Tasks may have supporting files (CSV, JSON, images, etc.) with the same number prefix:

• 0001_fix-soft-404.md - the task file
• 0001_Tabelle.csv - supporting data for the task

When marking a task as done, also rename supporting files with the DONE_ prefix.

Todo File Structure

Each todo file should contain:

---
title: Task Title
status: ready
tags:
- todo
- agent-todo
---

## Problem / Context

Description of the problem or context for the task.

## Tasks

- [ ] Task item 1
- [ ] Task item 2
- [ ] Ask questions if anything is uncertain

## Progress, Decisions etc.

### YYYY-MM-DD: Progress Entry Title

Description of what was done, decisions made, etc.

Frontmatter Fields

Every todo file starts with YAML frontmatter (--- delimiters) containing:

title

A human-readable title derived from the filename:

1. Strip DONE_ prefix if present
2. Strip the numeric prefix (e.g. 0001_)
3. Replace hyphens and underscores with spaces
4. Capitalize the first letter

Example: DONE_0042_fix-soft-404-errors.md → Fix soft 404 errors

status

Tracks the lifecycle of a todo. Values and transitions:

Status	Meaning	Transitions to
new	Created but not yet fleshed out	ready
ready	Has content, ready to work on	doing
doing	Currently being worked on	done, ready
done	Completed	archived
archived	Archived (reserved)	—

• A file with the DONE_ prefix should always have status: done.
• When a file has meaningful content (problem description, tasks), use ready.
• A freshly created empty file uses new.

tags

Every todo file should include the following tags:

tags:
- todo
- agent-todo

Workflow

1. Reading a Todo

When assigned a task:

1. Read the todo file to understand the task
2. Update the frontmatter status from ready → doing
3. Note any prerequisites or context
4. Check for existing progress entries

2. Working on a Task

While working:

1. Ask questions if anything is unclear - add user's answers to the file
2. Document decisions made during implementation
3. Track progress with dated entries

3. Adding Progress Notes

Add progress entries with this format:

### YYYY-MM-DD: Brief Description

**What was done:**

- Item 1
- Item 2

**Decisions made:**

- Decision 1 (with reasoning)

**Outstanding questions:** (if any)

1. Question 1?

4. Marking as Done

When task is complete:

1. Update the frontmatter status to done
2. Add a final progress entry documenting completion
3. If the file has checkboxes, mark them all as [x]
4. Rename the file with DONE_ prefix

Best Practices

1. Be verbose in progress notes - Future agents will read these
2. Date all entries - Use format YYYY-MM-DD
3. Document failures too - "Attempted X, did not work because Y"
4. Link to related files - Reference files that were created/modified
5. Ask before assuming - Add questions to the file and ask the user
6. Update internal docs - After completing a task, update relevant documentation

Finding Tasks

Read the configured todos directory from .agent-todos.local.json (todosRoot), defaulting to docs/agent-todos. If the config is not found in the project root (e.g., inside a git worktree), run git rev-parse --git-common-dir and check the parent of that path. Substitute <todos-dir> below with the resolved value.

To list all open (not done) tasks:

find <todos-dir> -name "*.md" ! -name "DONE_*" -type f

To list all completed tasks:

find <todos-dir> -name "DONE_*.md" -type f

To find tasks ready to be picked up (by frontmatter status):

grep -rl "^status: ready" <todos-dir>/
