Most tools have clearly distinct purposes: find_todos ranks priorities, scan_todos_raw returns an unranked list, search_todos does fuzzy searches, resolve_todo marks completion, and get_streak_status/aggregate_debt handle stats. The main potential confusion is between find_todos and scan_todos_raw, as both scan for TODOs, though the ranking distinction helps.

All tool names use lowercase snake_case with leading verbs (find, resolve, scan, search, get, aggregate), forming a consistent pattern. Minor deviations exist: resolve_todo is singular while most others are plural, and scan_todos_raw appends 'raw' as a modifier, slightly breaking the simple verb_noun structure.

Six tools are well-scoped for a tech debt tracking server. Each tool serves a distinct aspect—scanning, ranking, searching, resolving, streak stats, and cross-repo aggregation—so the count feels appropriate without being sparse or bloated.

The tool surface covers the core lifecycle: scanning and ranking TODOs, searching for specific items, resolving them, and tracking streaks across repositories. Minor gaps exist, such as no ability to reopen a resolved TODO or add a TODO, but these are acceptable limitations for a tech debt scanner.
