What's shipping in ArgosBrain — runtime hooks, agent-companion improvements, language adapters, performance work. We ship every couple of weeks. Subscribe to the GitHub releases feed for a notification on every cut.
Six weeks of focused work on things you'll actually feel — branch-aware comparison, runtime hooks, live ingest progress, aggressive vendored-skip, and a Free tier that no longer holds anything back except more than one repo at a time.
Open a worktree, ingest the branch, and Argos keeps both brains live in one MCP session.
Every search / recall / callers call surfaces the branch result alongside the main-branch baseline so you can see, in one shot, what your refactor actually changed.
Nobody else in this category ships this.
MCP notifications/progress stream during ingest_codebase, every 500 ms, with the
file currently being parsed plus a phase label
([1/4] Scanning → [4/4] Indexing → [done]).
The agent's chat shows real-time motion instead of a frozen tool call.
Default-aggressive skip for __tests__, __snapshots__, *.stories.tsx, *.d.ts, generated & protocol code, and the long-tail of vendored / fixture dirs.
Measured on a 15 685-file open-source monorepo — ingest dropped to 10 061 files (−36 %), proportional ETA reduction.
Opt-in flag re-enables tests for skills that need them (test-gap-analyzer, dead-code).
Claude Code PreToolUse hook fires before every Grep / Read / Glob
and injects an "also try mcp__argos__symbol_exists" nudge into the agent's context.
Non-blocking — Grep stays for free-text. Argos surfaces structural data
(exact file:line, callers, NoConfidentMatch) Grep can't see.

Sinks at all three levels, reachability + blast-radius, dead-code, API & architecture diffs — on Free.
The only Free→Pro gate is multi_project: bind to one repo at a time, swap with argosbrain abandon-primary.
Strategy: convert via experience.
