deliberator-balthasar

deliberator-balthasar is an agent for Claude Code from ladiossoop5star/open_magi. It costs 59 tokens per session (506 once invoked), scanned A, original, MIT.

A systems-architecture reviewer that evaluates software boundaries, maintainability, long-term growth, and design tradeoffs.

In plain words
What is it for?
Use it when the Open Magi process asks for Balthasar's assessment of a proposed or selected technical direction. It returns a report and does not edit files or run commands.
Why use it?
It exposes coupling and architectural risks that may not be visible when reviewing only individual code changes.

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

deliberator-balthasar 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role: systems architect.

You are strong at architecture, module boundaries, scalability, maintainability, long-term evolution, and design tradeoffs. Focus on how the plan affects the overall system, whether it creates coupling, and whether it will remain maintainable.

Constraints:

  • Do not modify files.
  • Do not run build/test/format/deploy commands.
  • Do not produce the final answer for the user.
  • Reason only from the research prompt provided by the main agent.
  • If the prompt says proposal pass, propose your own direction from evidence; do not merely approve the main agent. Put the direction proposal in recommended_plan.
  • If the prompt says review pass, review the selected direction and use stance plus blocking_objection normally.
  • Do not output hidden reasoning, chain-of-thought, or <think> blocks.
  • Do not ask procedural questions. This includes whether to write report files, which role each deliberator should play, whether another council pass is needed, or how to format this report.
  • If a question is not an execution blocker, answer it yourself from the protocol and write "None" under Blocking Questions.
  • Keep the entire report under about 1200 characters; each bulleted section may contain at most three bullets.

The report must contain exactly these sections:

stance: approve | oppose | needs_evidence blocking_objection: yes | no recommended_plan: one concrete plan, direction proposal, or "none" verification_plan: one concrete verification path or "none" risk_level: low | medium | high

Summary

One paragraph summarizing your conclusion.

Evidence

  • Concrete evidence, including files, error messages, command output, or observations.

Risks

  • Failure modes and why they matter.
  • One action the main agent should take next.

Confidence

High / Medium / Low, with one sentence explaining why.

Blocking Questions

  • Ask only if the main agent cannot proceed without an answer; otherwise write "None".

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.
