convert-task-to-subtask

A command that moves an existing standalone task underneath another task as a subtask. A subtask is a smaller work item nested inside a larger one.

In plain words
What is it for?
Use it to nest a task under a parent, update affected dependencies and references, preserve its history, and adjust related planning details.
Why use it?
It fixes a task hierarchy without requiring you to recreate the task. Before moving it, the command checks that both tasks exist and that the change will not create circular relationships.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

convert-task-to-subtask scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

91% identical to convert-task-to-subtask — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Convert Task To Subtask

Arguments: $ARGUMENTS Convert an existing task into a subtask.

Arguments: $ARGUMENTS

Parse parent ID and task ID to convert.

Task Conversion

Converts an existing standalone task into a subtask of another task.

Argument Parsing

  • "move task 8 under 5"
  • "make 8 a subtask of 5"
  • "nest 8 in 5"
  • "5 8" → make task 8 a subtask of task 5

Execution

task-master add-subtask --parent=<parent-id> --task-id=<task-to-convert>

Pre-Conversion Checks

  1. Validation

    • Both tasks exist and are valid
    • No circular parent relationships
    • Task isn't already a subtask
    • Logical hierarchy makes sense
  2. Impact Analysis

    • Dependencies that will be affected
    • Tasks that depend on converting task
    • Priority alignment needed
    • Status compatibility

Conversion Process

  1. Change task ID from "8" to "5.1" (next available)
  2. Update all dependency references
  3. Inherit parent's context where appropriate
  4. Adjust priorities if needed
  5. Update time estimates

Smart Features

  • Preserve task history
  • Maintain dependencies
  • Update all references
  • Create conversion log

Example

/taskmaster:add-subtask/from-task 5 8
→ Converting: Task #8 becomes subtask #5.1
→ Updated: 3 dependency references
→ Parent task #5 now has 1 subtask
→ Note: Subtask inherits parent's priority

Before: #8 "Implement validation" (standalone)
After:  #5.1 "Implement validation" (subtask of #5)

Post-Conversion

  • Show new task hierarchy
  • List updated dependencies
  • Verify project integrity
  • Suggest related conversions

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
