Desktop slash command handling needed a few follow-up guards after adding CLI parity. Bare /clear remains a local desktop reset, but /clear with arguments is rejected instead of silently discarding user text. Clear also resets cached slash commands, compact boundaries preserve CLI-provided text, and the help panel now discloses when the More section is truncated. Constraint: Preserve the desktop /clear fast path without accepting accidental arguments Rejected: Let /clear arguments fall through to the CLI | the CLI command still clears context and would keep the footgun Confidence: high Scope-risk: narrow Directive: Keep desktop-local slash command guards in sync with CLI command argument semantics Tested: cd desktop && bun run test src/stores/chatStore.test.ts src/__tests__/pages.test.tsx --run -t "clears local desktop chat state|ActiveSession routes /help" Tested: bun test src/server/__tests__/conversations.test.ts Tested: cd desktop && bun run lint Tested: git diff --check Not-tested: Full pages.test.tsx because unrelated locale-sensitive assertions are already present in that file
