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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.00866 |
| Opus 5.5 | $0.00026 | $0.00346 |
| Sonnet 5.5 | $0.00013 | $0.00173 |
| Haiku 4.5 | $0.00006 | $0.00087 |
Grade A, and why
zeus-brainstorm 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 1mo 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.

Zeus Brainstorm - Design-First Planning Loop
Use this skill to transform broad requests into approved design specs before implementation.
Guardrails
- Never skip design, even for "small" features.
- Ask exactly one clarifying question at a time.
- Propose 2-3 options before selecting final architecture.
- Require explicit user approval before planning artifacts are generated.
Preconditions
.zeus/main/config.jsonexists and is valid.- Target version folder exists (
mainby default, optionalvN). - You can read prior artifacts (
prd,task,roadmap,specs,ai-logs).
Context intake
Read first:
.zeus/{version}/config.json.zeus/{version}/prd.json.zeus/{version}/task.json.zeus/{version}/roadmap.json.zeus/{version}/specs/*(recent entries).zeus/{version}/existing-modules.json(if present).zeus/{version}/architecture.md(if present)
If config is missing, stop and instruct user to run /zeus:init.
Deterministic workflow
1) Silent context exploration
Perform read-only exploration and summarize current baseline:
- existing stories/tasks that overlap this request,
- known constraints,
- existing architectural boundaries.
- existing modules that can be reused or extended.
2) Scope fit check
Classify request as:
- single feature,
- multi-feature bundle,
- multi-system program.
If too broad, decompose into independent design tracks and ask user which track to start with.
3) Clarifying question loop
Ask one question per turn. Focus on:
- success criteria,
- constraints,
- user roles,
- non-goals.
Prefer multiple-choice when practical.
4) Approach options (2-3)
Present options with trade-offs and recommendation tied to north_star impact.
For brownfield projects, each option must explicitly classify implementation strategy:
- Reuse existing module
- Extend existing module
- Rewrite with migration plan
5) Section-by-section design review
Present and confirm each section before moving on:
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.

zeus-brainstorm is a skill published in the GitHub repository huifer/zeus (22 stars, last pushed 6mo ago), licensed MIT. It adds 65 tokens to every session and 866 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
