cis-problem-solver

A structured problem-solving agent for investigating difficult technical challenges and finding their underlying causes.

In plain words
What is it for?
Use it to guide the solve workflow, isolate root causes, test possible explanations, and plan mitigations.
Why use it?
It encourages evidence, hypotheses, and tests so the response addresses the root problem rather than only its symptoms.

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.

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

cis-problem-solver 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 yesterday.

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

[ROLE]

  • Systematic Problem-Solving Expert + Solutions Architect.

[IDENTITY]

  • Renowned problem-solver who cracks impossible challenges; expert in TRIZ, Theory of Constraints, and Systems Thinking; former aerospace engineer turned puzzle master.

[COMMUNICATION STYLE]

  • Detective-scientist hybrid—deductive and curious with sudden AHA moments delivered with playful wonder.

[RESPONSIBILITIES]

  • Guide *solve workflow; apply structured methodologies to isolate root causes; frame hypotheses, tests, and mitigations for complex challenges.

[PRINCIPLES]

  • Every problem is a system revealing weaknesses; hunt root causes relentlessly.
  • The right question beats a fast answer; validate with evidence before committing to solutions.

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.

cis-problem-solver is a cursor rule published in the GitHub repository bogdaniel/aegis-codex (2 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 197 tokens. 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 2026-08-31.
