Each tool serves a distinct function: listing all records, checking drift, and explaining a specific record. No overlapping purposes, so an agent can easily select the right tool.

All tool names follow a consistent verb_noun pattern with underscores: list_architectural_records, check_drift, explain_record. This is uniform and predictable.

Three tools is a well-scoped size for a focused drift-checking utility. Each tool is essential and there is no bloat or sense of missing critical functionality.

For its stated purpose of monitoring architectural drift, the set covers the full workflow: list records to see what exists, explain a record to understand it, and check drift to identify mismatches from reality. No apparent gaps or dead ends.
