IntelliJ Plugin v0.491.0 Release Notes

Changes below are new since the last stable IntelliJ plugin, v0.488.0-stable.

Improvements

  • The agent now asks for your approval before reading a file that looks sensitive — .env files, private keys and certificates, and credential- or secret-named files — as well as any file excluded by your .augmentignore. Directory listings are unaffected, and .gitignore is still not treated as a read boundary.
  • MCP servers reached over HTTP, SSE, or Streamable HTTP now go through your configured HTTP proxy, so MCP tools work on machines that require a proxy for outbound traffic.
  • Skills with invalid SKILL.md frontmatter are now shown in Settings with an actionable error instead of being silently dropped. An invalid skill also no longer hides a valid skill of the same name.

Reliability & Performance

  • The plugin's sidecar process can now use up to 4096 MB of heap, instead of Node's default ceiling of roughly 1.7 GB, so loading a very large conversation no longer exhausts memory. If it still runs out, you now get an explicit out-of-memory message instead of the sidecar disappearing silently. The ceiling can be overridden with the -Daugment.sidecar.maxOldSpaceSizeMb IDE system property.
  • Chat now automatically retries a response that is interrupted part-way through the stream, instead of ending the turn with an error you have to resend.
  • Opening Find Action no longer freezes the UI while the BYOK actions read your stored credentials; that lookup now runs off the UI thread.
  • After a restart, a turn that was interrupted now stays finished. Previously late startup loading could revive it, leaving the conversation appearing to still generate with tool calls stuck unresolved.

Bug Fixes

  • Fixed remote tool integrations (GitHub, Linear, Notion, and others) disappearing from Settings when the first tool fetch happened before sign-in completed. The list now heals as soon as you sign in, instead of staying empty for up to an hour or until you restart the IDE.
  • Fixed the agent being unable to read a file by absolute path from outside the project's content roots, such as a plugin-installed skill under ~/.augment/skills/.
  • Fixed a response that hits the model's output limit with no tool call ending as a silently truncated success. It is now surfaced as an interrupted response.
  • Fixed agent checkpoints failing to save for files in deeply nested workspaces, where the generated checkpoint filename exceeded the filesystem's limit. Existing checkpoint filenames are preserved.
  • Fixed a git checkout that deletes and immediately recreates a file racing the file watcher into deleting the freshly recreated file.
  • Fixed a chat message whose Markdown could not be parsed breaking the rendered response. It now shows an inline "Failed to render Markdown." notice, and rapid streaming updates always settle on the latest content.
  • Fixed a failed MCP Tool Search setting write in Settings being reported as a load failure, which made the whole MCP server list look broken.

VSCode Extension 0.901.1 Release Notes

New Features

  • Chat submit is now a rebindable VS Code keyboard shortcut. "Submit Chat Message" (Enter) and "Submit Chat Message Immediately" (Ctrl+Enter / Cmd+Enter) appear in Keyboard Shortcuts and can be remapped.

Improvements

  • Workspace-defined Augment hooks now run only in trusted workspaces. Command hooks supplied by a workspace stay disabled until you grant workspace trust, and are armed as soon as trust is granted.
  • The agent now asks for approval before viewing sensitive files — .env files, private keys and certificates, credential- and secret-named files, and paths excluded by .augmentignore.
  • Skills in .augment that fail to parse are now listed in Settings with the reason they were rejected, instead of disappearing silently.
  • MCP Tool Search in Settings now distinguishes a failure to save your changes from a failure to load the current configuration.
  • Remote MCP servers (HTTP and SSE) now honor the HTTP_PROXY and HTTPS_PROXY environment variables.

Reliability & Performance

  • Chat responses now recover from mid-stream interruptions automatically. Recovery is suppressed after a tool call has already completed, so tools are never re-executed by a retry.
  • A stream that ends abnormally now reports a neutral, retriable "response was interrupted" message instead of guessing that your network connection failed.
  • Recovered chat turns settle into a finished state. Tools that were running when a conversation was interrupted no longer appear to run forever after it is restored.
  • The conversation you are working in is preserved when the extension host restarts or reactivates.
  • Remote tool integrations no longer disappear when sign-in finishes while the extension is still starting up.

Bug Fixes

  • Responses cut short by the model's output limit are no longer reported as complete. Chat now shows an explicit truncation failure.
  • Markdown that fails to parse now renders an inline fallback message instead of leaving the response blank.
  • Agent checkpoints in deeply nested workspaces no longer fail to restore because of over-long checkpoint filenames.
  • Files that Git recreates during a checkout are no longer deleted again by the agent's checkpoint file watcher.

Auggie CLI 0.36.0 Release Notes

New Features

  • Reasoning Effort Flag: Added a flag to control the model's reasoning effort from the CLI.

Bug Fixes

  • Fixed a crash that could occur when replaying a session summary that included unsupported thinking content.
  • Removed the `secret get --reveal` flag since it did not work.
  • The daemon now validates the host's Git version at startup and reports a clear error if it's too old.
  • Fixed the agent failing to parse file view ranges from malformed tool calls.
  • Improved error messages when an MCP server's header secret configuration fails.
  • Fixed prompt module output being cut off before completion.
  • Fixed duplicate error notifications when a VFS sync failed.
  • Extended the knowledgebase download timeout to prevent failures on large codebases.
  • Patched security vulnerabilities identified in a routine dependency scan.
  • Fixed several issues where VFS syncing could destroy or resurrect deleted files.

IntelliJ Plugin v0.488.0 Release Notes

Changes below are new since the last stable IntelliJ plugin, v0.482.3-stable.

Improvements

  • Command hooks supplied by a repository's own `.augment/settings.json` now run only in projects you have marked as trusted. In an untrusted project those hooks are blocked; hooks you configure yourself at the user, system, or plugin level continue to run as before. Changing a project's trust state takes effect on the next hook event, with no restart needed.
  • MCP servers that announce a changed tool list during a session are now picked up automatically. Previously the tool list was read once at startup and could go stale for the rest of the session.
  • MCP servers are now verified with a real round-trip at startup, so a server that completes its handshake but cannot actually service calls no longer shows as connected.
  • Removing an MCP server now sticks. Previously a removed server could reappear when the set of active servers was rebuilt.

Groundwork

  • Included early groundwork for a future guided migration experience. It is not enabled in this release and has no effect today.

Reliability & Performance

  • Chat now recovers quickly when a response stream drops mid-way. Previously an interrupted request could keep spinning until it eventually surfaced a "Request appears to have stalled" message; it now surfaces a retriable failure promptly so you can try again.
  • Your most recent conversations are no longer lost on restart after a long chat history grows past the webview's storage limit. Previously the conversation list could revert to an earlier point.
  • Saving a conversation that times out or fails is now retried automatically instead of being marked saved, and concurrent saves of the same conversation no longer pile up.
  • Long-running MCP tool calls now respect the configured timeout, and a tool result that does not match its declared schema is passed through instead of failing the whole call.
  • Long conversations that cross a summarization boundary no longer fail with a provider error on models that return reasoning content.
  • Chat startup is more tolerant of a slow local connection between the chat panel and the plugin, and retries only the cases that can succeed on a retry.
  • Refreshing a project's source roots now tolerates files that have gone away mid-refresh instead of failing the refresh.

Bug Fixes

  • Fixed the chat panel missing indexing progress and the initial codebase summary when the panel was opened after indexing had already started. The current indexing state is now replayed once the panel is ready, including after a panel reload.
  • Fixed the Context Usage popover overstating how full the context window was by counting MCP tool definitions twice. Tool definitions are now counted once, and the breakdown reconciles with the reported total.
  • Fixed a "Failed to render" error in chat caused by a code block whose language tag was unrecognized. Unknown languages now fall back to plain text.
  • Fixed a "Failed to render" error in chat that could appear for conversations saved by an older version of the plugin.

Compatibility

  • Added support for JetBrains 2026.2 IDEs (build 262). The plugin was previously capped at 2026.1.
  • The plugin now requires JetBrains IDEs 2025.2 (build 252) or newer. It previously installed on 2024.2 and later. If you are on an IDE older than 2025.2, this update is not offered and your currently installed version keeps working; update your IDE to 2025.2 or newer to receive further plugin updates.
