nano-spec: Manage task specifications

A lightweight task specification tool with 4 documents (README, todo, doc, log).

Arguments

• $ACTION: The action to perform (create, status, update)
• $TASK_NAME: The task folder name (kebab-case recommended)
• $DESCRIPTION: Brief description (required for create, optional for others)

Actions

create

Create a new nano-spec task pack.

Usage: /nano-spec create my-task "Task description"

1. Create folder tasks/$TASK_NAME/ if tasks/ exists, otherwise create at project root
2. Generate 4 files based on the description, following the exact structure below:

README.md

Output Format (create)

After creating files, summarize:

Created nano-spec: tasks/$TASK_NAME/
- README.md  (background, goals, scope)
- todo.md    (X tasks, Y acceptance criteria)
- doc.md     (technical decisions template)
- log.md     (initialized)

Next: Review and refine the generated spec

status

Show current progress of a task.

Usage: /nano-spec status my-task

1. Read tasks/$TASK_NAME/todo.md and log.md
2. Summarize:

- Completed tasks vs total - Current blockers (if any) - Last log entry date

update

Update an existing nano-spec.

Usage: /nano-spec update my-task "What to update"

1. Read existing files in tasks/$TASK_NAME/
2. Make requested updates
3. Add entry to log.md with today's date
