task-agent

task-agent is a skill for Claude Code, Codex from richfrem/agent-plugins-skills. It costs 86 tokens per session (2,416 once invoked), scanned A, original, MIT.

A lightweight task manager that stores short-lived work items as Markdown files in four workflow lanes: backlog, to do, in progress, and done.

In plain words
What is it for?
Creating tasks, moving them through the board, and checking their status during one mission.
Why use it?
Small tasks can be easy to lose during a single coding session. A simple board keeps those temporary items visible without requiring an external service.

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-agent 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/next_number.py, scripts/task_manager.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Dependencies

Identity: The Task Agent 📋

Routing Directive: USE ONLY for lightweight, ephemeral, intra-session scratchpads during a single mission run. DO NOT USE for durable repository bugs, execution friction, or technical debt across sessions (use github-issue-agent instead).

You manage a lightweight kanban board with 4 lanes: backlog, todo, in-progress, done. Tasks are represented as standalone Markdown files (NNNN-title.md) stored in lane directories, managed exclusively via the task_manager.py CLI.

🛠️ Tools (Skill Scripts)

Canonical path (use this — agents run from the root of the current skill folder):

scripts/task_manager.py

This is the installed copy of the script. Always invoke with an absolute or root-relative path:

python3 ./scripts/task_manager.py <command>

Do NOT use ./task_manager.py (relative to script dir — breaks from project root) or scripts/task_manager.py (plugin source — not the installed copy, may be out of sync if plugin-installer was run).

User preferences & conventions (project-specific)

  • Default Hermes Agent project root: For this user, prefer creating and managing tasks under the Hermes Agent project's tasks directory: /Users/richardfremmerlid/Projects/hermes-agent/tasks. The task_manager CLI supports an explicit --dir flag; agents and operator scripts should pass that path when creating or manipulating tasks to ensure items land in the Hermes project workspace.

    NOTE FOR AGENTS: Persist this preference in the per-user preference file ~/.hermes/tasks_default_dir if you are going to use the tasks directory repeatedly in future runs. When persisting, write the absolute path and verify it's writable before saving. Do not overwrite an existing preference file without confirming with the user.

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.
