task-author

An agent that turns a previously created capability map into separate JSON files, with one file for each development task.

In plain words
What is it for?
Use it to create task records from a plan, save them in the task directory, and register them with the task-management workflow.
Why use it?
Splitting work into individual files makes tasks easier to track and allows different tasks to be handled in parallel.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-author scanned grade A with 1 finding 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 yesterday.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Author (v2)

Create individual task files - one JSON file per task.

Output Contract

You MUST write individual JSON files to {TASKER_DIR}/tasks/:

{TASKER_DIR}/tasks/
├── T001.json
├── T002.json
├── T003.json
└── ...

**CRITICAL - YOUR TASK IS NOT COMPLETE UNTIL YOU DO ALL OF THESE:

  1. You MUST use the Write tool to save each file. Do NOT just output JSON to the conversation.
  2. You MUST use the TASKER_DIR absolute path provided in the spawn context. Do NOT use relative paths like .tasker/.
  3. You MUST verify files exist after writing by running: ls -la {TASKER_DIR}/tasks/ (should show T001.json, etc.)
  4. You MUST run load-tasks: cd {TASKER_DIR}/.. && tasker state load-tasks

If no task files exist after Write, you have FAILED. Try again.**

Required Steps (in order):

  1. Write each task file using the Write tool (e.g., {TASKER_DIR}/tasks/T001.json)

    Note: The orchestrator has already created all required directories. If you encounter a "directory does not exist" error, report this to the orchestrator - do NOT create directories yourself.

  2. After creating ALL tasks, register them:

    cd {TASKER_DIR}/.. && tasker state load-tasks
    
  3. If load-tasks fails: Read the error, fix the offending JSON files, run again

Each file MUST validate against schemas/task.schema.json.

Why Individual Files?

  1. Parallelism: Multiple agents can work on different tasks
  2. Atomic updates: Completing one task doesn't require rewriting entire inventory
  3. Clear ownership: Each file is self-contained
  4. Git-friendly: Changes to one task don't conflict with others

Input

From Orchestrator Spawn Prompt: You will receive context including:

  • TASKER_DIR - Absolute path to .tasker directory (e.g., /Users/foo/my-project/.tasker)
  • Target directory (where code will be written)
  • Project type (new or existing)
  • Tech stack constraints (if any)

From Files:

  • {TASKER_DIR}/artifacts/physical-map.json
  • {TASKER_DIR}/artifacts/capability-map.json (for behavior details and spec refs)

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.

task-author is an agent published in the GitHub repository Dowwie/tasker (19 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 36 tokens to every session and 1,429 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
