Most tools have clearly distinct targets (single issue, JQL search, comments, links, my issues, project metadata). However, get_issue already returns comments and linked issues, so it partially overlaps with get_comments and get_related_issues, and get_my_open_issues is essentially a preset of search_issues. Descriptions do help clarify the intended use cases.

All names use snake_case with a verb_noun structure (get_issue, get_comments, get_related_issues, get_project_metadata, get_my_open_issues). The only deviation is search_issues, which is still readable and semantically appropriate for a query action rather than a fetch.

Six tools is well-scoped for a focused read-only Jira integration. Each tool maps to a distinct read operation with no filler or redundancy beyond the mild overlap noted.

The read-only surface covers the core read paths: fetch, search, comments, links/subtasks, assigned work, and project metadata. Minor gaps exist for read-only needs like attachments, worklogs, or listing all accessible projects, but these are workable omissions.
