…ommand The CLI query assembly kept only the last user line whenever it started with '/', silently discarding the context lines NBI had just appended for the same turn (attachment @-mentions, cell pointers, output context) — the footgun previously documented in extension.py's on_message. Extract the join into assemble_client_query: control-only commands (/clear, /cost, ...) still drop the context since it is meaningless to them, while any other command is moved to the front of the query (the CLI only recognizes a command at the start) with the context lines preserved after it, so custom skill and plugin commands receive the user's attachments. Promote claude_sessions' control-command set to a public name (adding /context) and reuse it as the single source of truth.

LGTM. Nice fix for the context-dropping footgun. The control-command allowlist plus front-hoisting is a clean approach, and I appreciate the documented rationale and the manual verification that the context now rides through into the command arguments.

assemble_client_query:/clear,/cost, ...) still drop the context — it is meaningless to them;claude_sessions' control-command set to a public name (CONTROL_SLASH_COMMANDS, adding/context) and reuse it as the single source of truth; the private alias remains for compatibility.Testing
/nbi-echocommand: an NBI-appended context line (current-directory pointer) thatmaindrops for a slash-command turn now rides through into the command's$ARGUMENTS, confirming the context is preserved.
