WHAT IT DOES

What agenticow_diff does on Hamza Agent Hub 252

AI agents call agenticow_diff to retrieve information from Hamza Agent Hub 252 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why agenticow_diff is rated Low

This tool only reads and surfaces diff information (added, overridden, deleted vector IDs) between a branch and its lineage. It does not modify, delete, or execute anything — it is purely a preview/audit read operation. The description explicitly frames it as a preview tool before promotion, not the promotion itself.

From the tool's definition show what a branch changed relative to its lineage: {added, overridden, deleted} vector-id lists... preview the exact merge... auditing what a branch actually wrote

FAQ

Questions about agenticow_diff

What does the agenticow_diff tool do? +

agenticow — show what a branch changed relative to its lineage: {added, overridden, deleted} vector-id lists. Use when you are about to promote and want to preview the exact merge, or when auditing what a branch actually wrote. Diffing by re-querying is wrong because deletions (tombstones) are invisible to a read — diff() surfaces them explicitly. Requires the branch was opened with edit tracking (default on). It is categorised as a Read tool in the Hamza Agent Hub 252 MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on agenticow_diff? +
