root_cause_agent

root_cause_agent is an agent for coding agents from BingHanOfUESTC/open_agent_team. It costs 25 tokens per session (107 once invoked), scanned A, original, MIT.

An agent that develops ranked hypotheses about what caused a problem, based on available evidence. It also lists what should be checked and possible fixes.

In plain words
What is it for?
Use it for evidence-based debugging or incident analysis when you need candidate causes, verification steps, and repair options.
Why use it?
It helps separate likely root causes from guesses and makes the next investigation steps explicit. The description does not specify which kinds of problems it handles.

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

root_cause_agent 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 3d 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.
