Scored across 33 tools
Most tools are documented with explicit cross-references and 'prefer X' guidance, but the set contains several closely overlapping note-edit tools (vault_patch_note, vault_replace_in_note, vault_replace_span, vault_insert_at_anchor, vault_delete_span, vault_write_note) whose boundaries an agent must reason through carefully. The search/discovery family also overlaps heavily: vault_search, vault_search_by_tag, vault_search_by_folder, vault_search_by_property, vault_list_notes, vault_recent_notes, and vault_list_files each have justified niches, but choosing among them is not effortless.
Almost all tools use a predictable vault_verb_noun snake_case pattern, with clear names like vault_list_notes, vault_read_note, vault_create_task, and vault_update_properties. Minor deviations such as vault_recent_notes, vault_memory_recall, and the search_by_* family are still readable and consistent enough not to cause confusion.
At 33 tools, the surface is large even for a full-featured Obsidian server spanning notes, search, links, files, memory, tasks, and daily notes. While most tools have domain justification, the total is heavy and includes multiple near-duplicate edit and discovery tools that make the set harder to navigate than necessary.
Core vault workflows are well covered: note CRUD, section edits, property updates, search, tags, backlinks, files, memory, tasks, and daily notes. Minor gaps remain around non-markdown file write/delete, folder management, and broader attachment operations, but agents can work around most of these.
