v0.0.6 is the “open harness” release: research quality, user-defined tools, and MCP servers — without claiming production polish.

Shipped

Files and shell

  • write_file + edit_file as the canonical file surface (replacements + fuzzy diff)
  • grep_file always-on; read_file offset/limit
  • batch_replace / streaming tail UI experiments (later consolidated)
  • Windows-oriented run_shell guidance in tool errors

Research

  • Source credibility tiers and contradiction surfacing
  • Domain-generalized research rules in the system prompt (context-aware, not web-only)

Extensibility

  • Dynamic tools — model-authored tools persisted to disk
  • activate_tools for sub-agent provisioning
  • MCP client + autonomous capability-gap suggestions
  • Progress events from long-running tools (no silent multi-minute stalls)

Web

  • SSE reconnect hardening and harness heartbeat for rate-limit storms
  • Provider retry lines visible regardless of verbosity setting

Not yet

  • Browser automation, resumable streaming writes, harness Settings modal
Next: v0.0.7 →World context, JSONL sessions, agenda/scheduler tools.
