task-planner

task-planner is an agent for coding agents from alekspetrov/navigator. It costs 35 tokens per session (765 once invoked), scanned A, original, no licence file.

An implementation-planning helper that breaks features, refactors, and other complex changes into tasks and estimates the effort involved.

In plain words
What is it for?
Use it to plan new features, refactoring work, and other multi-step implementation projects.
Why use it?
It gives you a concrete work plan before coding, so large changes are easier to understand and organise.

Part of the navigator plugin — 32 skills, 2 agents shipped together

Install

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.

agentmods
npx agentmods add agents/alekspetrov/navigator/task-planner
Clone the repo
git clone --depth 1 https://github.com/alekspetrov/navigator

Or install navigator, the plugin that ships this one along with the rest of its 32 skills, 2 agents.

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-planner 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 5d 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.

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.
