Search/list formalization templates. Returns skeletons, slots, normalization recipes, usage metadata. Find template before chiasmus_verify or chiasmus_formalize. query:
AI agents call chiasmus_skills to retrieve information from Chiasmus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
chiasmus_skills is a lookup/query tool that searches and lists templates. It retrieves metadata about available formalization templates but does not create, modify, delete, or execute operations. The description explicitly indicates read-only operations (search, list, return metadata).
From the tool's definition Tool performs 'Search/list formalization templates' and 'Returns skeletons, slots, normalization recipes, usage metadata' - purely retrieval and listing operations with no side effects.
Documented attack patterns abuse exactly the kind of access chiasmus_skills gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Chiasmus, and nothing reaches the server without passing your rules. This is the rule we recommend for chiasmus_skills:
{
"version": "1",
"default": "deny",
"tools": {
"chiasmus_skills": {}
}
}chiasmus_skills is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search/list formalization templates. Returns skeletons, slots, normalization recipes, usage metadata. Find template before chiasmus_verify or chiasmus_formalize. query:. It is categorised as a Read tool in the Chiasmus MCP Server, which means it retrieves data without modifying state.
Register the Chiasmus MCP server in PolicyLayer and add a rule for chiasmus_skills: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Chiasmus. Nothing to install.
chiasmus_skills is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the chiasmus_skills rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for chiasmus_skills. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
chiasmus_skills is provided by the Chiasmus MCP server (yogthos/chiasmus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
