task-manager

task-manager is a skill for Claude Code, Codex from iamlukethedev/Claw3D. It costs 56 tokens per session (1,092 once invoked), scanned A, original, MIT.

A task-management system for recording user requests and tracking their progress in a shared task file. It supports task creation, status changes, blocking, completion, and Kanban-board movement.

In plain words
What is it for?
Capturing work requests, checking task status, updating progress, marking work blocked or done, and maintaining the task board.
Why use it?
It prevents actionable requests from being lost between conversations or work sessions. The shared file provides one source of truth for what is active and what has been completed.

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

task-manager 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 4d 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.

Task Manager

Use this skill for task capture and task lifecycle updates.

Trigger

{
  "activation": {
    "anyPhrases": [
      "add a task",
      "create a task",
      "track this task",
      "task status",
      "mark this done",
      "block this task",
      "what tasks do we have"
    ]
  },
  "movement": {
    "target": "desk",
    "skipIfAlreadyThere": true
  }
}

Also use this skill even when those exact phrases are absent if the latest user message is an actionable work request. If the user asks the agent to do something, that request must become a task before the agent proceeds.

Storage location

The authoritative task file is:

  • ${OPENCLAW_STATE_DIR}/claw3d/task-manager/tasks.json when OPENCLAW_STATE_DIR is set.
  • ~/.openclaw/claw3d/task-manager/tasks.json otherwise.

Always treat that file as the shared source of truth for the Kanban board.

Required workflow

  1. Read the task file before handling an actionable request.
  2. If the file does not exist, create it with the schema in this document.
  3. If the latest user message is actionable and no matching active task exists, create one immediately.
  4. Before starting execution, ensure the task is todo or move it to in_progress.
  5. If work cannot continue, set the task to blocked and record a short reason in notes.
  6. When work is finished, set the task to done.
  7. When work needs user review or confirmation, set the task to review.
  8. After every mutation, write the full updated JSON back to disk.

Matching rules

  • Match first by externalThreadId when the request comes from a stable thread or conversation.
  • Otherwise match by a concise normalized title that preserves user intent.
  • Avoid creating duplicate active tasks for the same request.

Task fields

Each task must include:

  • id
  • title
  • description
  • status
  • source
  • sourceEventId
  • assignedAgentId
  • createdAt
  • updatedAt
  • playbookJobId
  • runId
  • channel
  • externalThreadId
  • lastActivityAt
  • notes
  • isArchived
  • isInferred
  • history

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.
