Each tool occupies a distinct layer of the workflow: browse categories, list a rule index, fetch full rule details, statically scan a project, and generate a submission checklist. The index-vs-detail split between list_rules and get_rules is explicitly described (id+title vs full symptom/cause/fix), and lint_project (code scanning) is clearly separated from submit_checklist (pre-release checklist generation). No two tools appear to do the same thing.

All five names follow a strict snake_case verb_noun pattern (list_categories, list_rules, get_rules, lint_project, submit_checklist), with verb choice matching semantics (list for collections, get for detail, lint/submit for actions). No mixed conventions or vague standalone verbs.

Five tools is right-sized: two discovery tools, one detail tool, one enforcement tool, one release-workflow tool. Each earns its place with no filler or redundant wrappers.

The rule-reference → lint → pre-release checklist lifecycle is covered end to end, with category/severity filtering and id/category/full-detail fetch modes. Minor gaps: no keyword/symptom-based rule search (only category/severity/id), and lint_project has no scope options (e.g., single file, changed files) or severity-threshold configuration.
