The read tools (list_tickets, get_ticket_context, search_knowledge) are cleanly separated by scope: queue listing, single-ticket deep context, and policy lookup. The four save_* tools each produce a distinct artifact (assessment record, customer reply draft, escalation brief, KB article draft), though the assessment/escalation pairing requires reading the descriptions to see that escalation targets come from the assessment rather than being a separate judgment call.

All seven tools use a consistent snake_case verb_noun pattern (list_, get_, search_, save_), with save_ uniformly marking the write operations. Minor deviation: object nouns are inconsistently qualified (ticket_context vs response_draft vs the abbreviation kb_draft), so the family prefix is not fully uniform, but the pattern remains predictable.

Seven tools is well-scoped for a support-agent workflow lab: three reads covering queue, ticket context, and policy, plus four write-draft operations for each artifact type. No tool appears redundant or padded, and nothing obviously needed is missing from the count itself.

The write side covers assessments, reply drafts, escalations, and KB drafts, but there is no read-back surface: an agent cannot list or retrieve previously saved assessments, drafts, or escalations to verify or revise them, and there is no operation to advance or resolve a ticket's status. These gaps are partly intentional (human-in-the-loop, nothing is sent), but they leave the agent unable to confirm its own writes or work the ticket lifecycle.
