 770. **`claw cost/clear/memory/ultraplan/model` with trailing args fell to credential check** — dogfooded 2026-05-27 on `9e1be056`. Same fallthrough gap as #767/#769: these slash-only verbs had no multi-arg match arms, so `claw cost breakdown`, `claw clear --force`, `claw memory reset`, `claw ultraplan bogus`, `claw model opus extra` all became `CliAction::Prompt` literals, hitting `missing_credentials` at the gate. Fix: added `"cost"`, `"clear"`, `"memory"`, `"ultraplan"`, `"model" if rest.len() > 1` match arms, each returning `interactive_only:` + `\n`-delimited hint. Integration test `slash_only_verbs_with_args_return_interactive_only_not_credentials_770` asserts all five cases. 36 CLI contract tests pass.

 771. **`init extraarg` silently succeeded; `usage`/`stats`/`fork` with args fell to credential check** — dogfooded 2026-05-27 on `3a1d8838`. Two distinct gaps: (1) `claw init extraarg` returned `status:ok` with trailing positional ignored — `"init"` arm always returned `Ok(CliAction::Init)` regardless of `rest[1..]`; (2) `claw usage extra`, `claw stats extra`, `claw fork newbranch` had no match arms and fell to `CliAction::Prompt` + credential gate. Fixes: (1) added extra-arg check in `"init"` arm — rejects with `unexpected_extra_args:` prefix + `\n` usage hint; (2) added `"usage"`, `"stats"`, `"fork"` interactive-only arms. All four now return correct `error_kind` + non-null hint. 36 CLI contract tests pass. [SCOPE: claw-code] Source: Jobdori sweep on `3a1d8838`, 2026-05-27.

+772. **Slash command aliases bypassed `bare_slash_command_guidance` lookup** — dogfooded 2026-05-27 on `bf212b98`. `bare_slash_command_guidance()` only checked `spec.name == command_name`, not `spec.aliases`, so `claw yes`, `claw no`, `claw y`, `claw n`, `claw skill`, `claw cwd` all fell through (either to typo suggestions or `missing_credentials`). Should have returned `interactive_only:` guidance referencing the canonical form. Fix: (1) lookup changed to `spec.name == command_name || spec.aliases.contains(&command_name)`; (2) capture `canonical_name = slash_command.name`; (3) guidance strings updated to reference canonical form in remediation (e.g., `claw yes → /approve`, `claw n → /deny`, `claw skill → /skills`). 36 CLI contract tests pass.
