Roo Code 3.38 Release Notes (Combined)

Roo Code 3.38 adds Agent Skills and includes follow-up fixes for tool reliability, provider message formatting, and file reading.

Roo Code v3.38 Release

Agent Skills​

Roo now supports Agent Skills, which are portable skill folders containing instructions, scripts, and resources that the agent can discover and load on demand. This lets you package repeatable workflows and domain knowledge once and reuse them across projects to make results more consistent and reliable. (#10335):

📚 Documentation: See Skills for setup and usage.

QOL Improvements​

  • Slash commands can declare a target mode in their front matter, so triggering a command can switch Roo to the right mode first (#10344).
  • Removes the legacy “simple read file” tool path so file reading consistently uses the standard read_file tool (#10254).
  • Clarifies the navigation path for deleting a Roo Code Cloud account in the privacy policy, so you can find Security Settings faster (#10367).
  • Improves internal analytics consistency by recording custom tools the same way as MCP tools, which helps tool usage and error tracking stay accurate (#10364).

Bug Fixes​

  • Fixes an issue where some Claude Sonnet 4.5 requests could fail with HTTP 400 errors after context condensing (#10359).
  • Fixes an issue where manually condensing context while a tool is still running could trigger provider protocol errors, so tool runs and manual condenses can safely overlap (#10379).
  • Reverts a change for OpenAI-compatible providers to avoid message-format regressions related to text appearing after tool results (#10381).
  • Enforces the maxConcurrentFileReads limit for read_file, returning a clear error instead of silently ignoring the setting (#10363).
  • Improves the error shown when read_file is run on a directory by explicitly explaining the issue and suggesting list_files instead (#10371).
  • Fixes an issue where the "open source" link on roocode.com could point to a non-existent GitHub organization, so it reliably opens the correct repository (thanks jishnuteegala!) (#10377).

Misc Improvements​

  • Custom tools can import npm packages, and can load secrets from a same-folder .env file (#10336).

Provider Updates​

  • Removes the “OpenRouter Transforms” setting and stops sending the transforms parameter on OpenRouter requests (#10341).
