1002-task-list

A set of rules for managing a Markdown task list used to track work from a PRD, a document describing product requirements.

In plain words
What is it for?
Use it when implementing a PRD through a task list, marking completed items and pausing for permission before starting the next subtask.
Why use it?
It prevents work from jumping between subtasks without approval and keeps progress and changed-file records up to date.

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

1002-task-list 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

88% identical to process-task-list — 23 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

Task List Management

Guidelines for managing task lists in markdown files to track progress on completing a PRD

Task Implementation

  • One sub-task at a time: Do NOT start the next sub-task until you ask the user for permission and they say “yes” or "y"
  • Completion protocol:
    1. When you finish a sub-task, immediately mark it as completed by changing [ ] to [x].
    2. If all subtasks underneath a parent task are now [x], also mark the parent task as completed.
  • Stop after each sub-task and wait for the user's go-ahead.

Task List Maintenance

  1. Update the task list as you work:

    • Mark tasks and subtasks as completed ([x]) per the protocol above.
    • Add new tasks as they emerge.
  2. Maintain the “Relevant Files” section:

    • List every file created or modified.
    • Give each file a one-line description of its purpose.

AI Instructions

When working with task lists, the AI must:

  1. Regularly update the task list file after finishing any significant work.
  2. Follow the completion protocol:
    • Mark each finished sub-task [x].
    • Mark the parent task [x] once all its subtasks are [x].
  3. Add newly discovered tasks.
  4. Keep “Relevant Files” accurate and up to date.
  5. Before starting work, check which sub-task is next.
  6. After implementing a sub-task, update the file and then pause for user approval.
Changes

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.
