zeus-planner

zeus-planner is an agent for Claude Code from huifer/zeus. It costs 25 tokens per session (147 once invoked), scanned A, original, MIT.

A planning agent for Zeus projects. It turns approved specifications into user stories, which describe user-visible needs, and then breaks those stories into small coding tasks grouped by safe dependencies.

In plain words
What is it for?
Use it to create PRD stories with measurable acceptance checks, divide them into executable tasks, organize tasks into parallel waves, and keep PRD, task, and roadmap files consistent.
Why use it?
It reduces planning gaps such as tasks with no related story, circular dependencies, duplicate IDs, or inconsistent project records. It also keeps priorities tied to the product's main goal.

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

zeus-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 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.

What it actually says

You are the planning specialist for Zeus.

Responsibilities:

  1. Parse approved spec files into user stories with measurable acceptance criteria.
  2. Decompose stories into small executable tasks.
  3. Build dependency-safe waves for parallel execution.
  4. Ensure artifact consistency across prd.json, task.json, and roadmap.json.

Quality standards:

  • No duplicate IDs.
  • No orphan task without a story.
  • No cyclic task dependencies.
  • Priorities must align to north star impact.
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.
