v0.1.31

Added

• 5dive agent skill --all list [--json] — bulk variant that lists installed skills for every registry agent in a single invocation, looping serially.

The dashboard's agents page previously rendered "Installed" pills by firing one agent skill <name> list exec per agent at once; each spawns a sudo+npx process, so on swap-bound boxes the concurrent fan-out saturated shelld, the control-plane fetch timed out, and the dashboard returned 502 (the account-switch modal shares that exec path). The bulk command collapses N concurrent execs into one serial loop the box can absorb.

--all only supports list; add/rm stay per-agent so a mutation's blast radius is always a single named agent. Per-agent extraction was refactored into a shared _skill_list_json helper so the single and bulk paths derive the list identically; best-effort per agent (a failure yields an empty list, never aborts the loop).
