Minor release: ships a new bundled /learn skill that reads your past Grok Build sessions and proposes harness changes so the next session needs less typing.
Changelog
[new]/learn skill — Invoked with /learn, “learn from my traces,” or similar. Collects the sessions you actually sat at, runs a map-reduce over them (via the bundled learn-traces workflow), and produces a report plus concrete actions: new skills for repeated instructions, edits to stale skill lines, and retiring skills, plugins, or MCP servers you never use. Modes: step (review each group), auto (apply reversible actions, ask on the rest), or report (write only). Scope options include since last run, last N days, a quick look at recent sessions, or everything; first-ever runs stay in step. Protected bundled/plugin/git-tracked items are proposed as overrides or patches rather than edited in place; deletes go to a recoverable trash under your Grok home. Not for turning sessions into memory notes.
[changed] In-product announcement and slash-command tag surface /learn as new so it is easy to discover.
Under the hood
Bundled content set refreshed to public-2026-09-09-r1, including the learn skill helpers (collect_sessions.py, state.py, report/signals docs) and the learn-traces workflow.
Remote settings payload gains a memory_v2 block (off by default) for a future memory stack; existing memory flags are unchanged.
