Devin CLI adds 16color and nocolor theme modes

Added

• Add 16color and nocolor theme modes. 16color quantizes output to the 16 ANSI color palette (respects terminal color scheme). nocolor disables all color output for VT100 and other monochrome terminals.

• Support multi-root workspaces with additional directories beyond the session working directory.

• Add /workspace and /add-dir slash commands for listing and adding workspace directories at runtime.

• Add workspace-dirs config option for setting workspace directories programmatically.

• Add Ask mode (/ask) for read-only question answering without code changes

• Add /bug slash command for submitting bug reports from the stdio server

• Display a persistent warning banner when running in Windows Conhost, recommending Windows Terminal or Git Bash for a better experience.

• Ctrl+Left and Ctrl+Right now jump between words, matching standard Linux and Windows terminal behavior. Ctrl+Backspace and Ctrl+Delete delete words backward and forward respectively.

• Add custom subagent profiles: define specialized subagents with their own system prompts, tools, and models via AGENT.md files in your project’s agents/ directory (experimental)

• Add subagent and agent frontmatter fields for skills, allowing skills to run as independent subagents instead of inline (experimental)

• Add include_gitignored_files config option to include gitignored files in @ tab completion results (default: off)

• /undo-add-dir command to remove directories from the workspace.

• /rm-session command to delete sessions.

• Added request_scope tool for requesting read/write access to directories when running in sandbox mode

• Added sandbox mode system prompt that informs the agent about sandbox restrictions and how to request additional access

• The --sandbox flag and devin sandbox setup command are now available on all build channels (previously insiders-only)

• Add unicode_mode config option (auto/unicode/ascii) for terminals that don’t support Unicode glyphs

• Add devin version subcommand as an alias for devin --version

Changed

• Include the active interface mode in bug report details
• Migrate all config, data, and cache directories from ~/.config/cognition/, ~/.local/share/cognition/, and ~/.cache/cognition/ to devin/. A backward-compatibility symlink is created at each old path so older sessions continue working.
• Rename the project-level config directory from .cognition/ to .devin/. Existing .cognition/ directories are still read (with a deprecation warning) for backward compatibility.

Fixed

• Hooks defined in .claude/settings.json are now loaded by the CLI (both project-level and global ~/.claude/settings.json)

• Cmd+V now triggers clipboard paste in terminals that report it as a key event (e.g. when pasting non-text data like images)

• Fixed panic when piping CLI output to commands that close early (e.g. devin -p "..." | head).

• Fix partial agent output (thinking and content) being silently dropped when the agent stops with an error during streaming

• Fixed image uploads failing when the file extension doesn’t match the actual image format (e.g. a JPEG saved as .png). The MIME type is now detected from the image content rather than trusting the caller-supplied value.

• Fix devin mcp login failing against servers (e.g. Glean) that only allow /auth/callback as the OAuth redirect path

• Fix CLI freeze when pasting very long single-line text (e.g. JSON blobs, base64 strings) by collapsing pastes that exceed 5,000 characters

• Skills now display their true source path (e.g. .agents/skills/) instead of always showing .devin/skills/

• Fixed pasting text (Ctrl+V / bracketed paste) into slash command prompts like /bug

• Respect the disabled: true flag in MCP server configurations, so servers marked as disabled in Windsurf, Claude, or Devin config files are no longer loaded
