claude agents: workflow slash-commands missing from dispatch-input completion (regression-adjacent to #61424)

Summary

Inside an active Claude Code session, typing a slash-prefix surfaces autocomplete suggestions for workflows (user-defined /<name> workflow constructs) — but the same prefix in the claude agents dispatch input does not.

This appears adjacent to #61424 (fixed), but the workflow case still doesn't surface.

Environment

• Claude Code: 2.1.153
• OS: macOS (Darwin 25.5.0)
• Workflow under test: a workflow registered as /g9-sdlc in the target directory (described in agent view as [dynamic workflow] g9 feature SDLC: clarify → plan → gate → dev → review…)

Repro

1. In a repo that has a registered workflow (e.g. /g9-sdlc), start an active Claude Code session.
2. Type /sdl at the prompt. The completion popup correctly surfaces /g9-sdlc with its description.
3. From a shell, run claude agents (from a parent directory or any directory; the target repo is reachable via @<repo>).
4. In the dispatch input, type @<repo> /sd (where <repo> is the same repo that has /g9-sdlc registered).
5. Expected: the dispatch input suggests /g9-sdlc the same way the in-session prompt does.
6. Actual: only enter to create · esc to clear is shown — no slash-command suggestion.

Expected behavior

Per the agent view docs:

/<command> — Suggest skills and commands to dispatch as the prompt

Workflows are user-defined slash-commands and should be suggested the same way skills and built-in commands are.

Hypotheses (not asserted, just to narrow the search)

• The dispatch-input completion source may enumerate skills and commands but not workflow constructs.
• Or it may enumerate them from the parent CWD only and not from the @<repo>-resolved target directory.
