Before submitting your bug report

• I've tried using the "Ask AI" feature on the Continue docs site to see if the docs have an answer
• I believe this is a bug. I'll try to join the Continue Discord for questions
• I'm not able to find an open issue that reports the same bug
• I've seen the troubleshooting guide on the Continue Docs

Relevant environment info

Description

The Issues:
Mixed Command Syntax: I started with bash/Linux syntax (cd coding-agent && mkdir) which doesn't work in PowerShell. PowerShell uses different operators and syntax.

Directory Navigation Problem: When I used cd coding-agent and then pwd, the output still showed D:\Github\Coding CLI (root directory), which means the cd command didn't actually change directories properly.

Incorrect Path Handling: I was trying to use relative paths inconsistently. PowerShell is more strict about path resolution.

Move Command Execution: The Move-Item command may have appeared to succeed, but the subsequent Get-ChildItem shows we're still seeing the root directory contents, not the coding-agent directory contents.

Directory Creation Location: The original mkdir agents, mcp-servers, sdk-implementations... command created all directories in the root (D:\Github\Coding CLI) instead of inside the coding-agent folder because we weren't actually inside the coding-agent directory.

PowerShell Command Issues in Continue IDE

Root Cause Analysis

Based on analysis of the Continue IDE codebase, the directory setup command issues stem from mismatched expectations between the AI's command generation and PowerShell's actual syntax requirements.

Issues Identified

1. Mixed Command Syntax in AI Instructions

Location: core/tools/definitions/runTerminalCommand.ts

Problem: The tool definition contains generic platform detection:

const PLATFORM_INFO = `Choose terminal commands and scripts optimized for ${os.platform()} and ${os.arch()} and shell ${getPreferredShell()}.`;

Issue: The AI is told to "optimize for powershell.exe" but isn't given concrete examples of proper PowerShell syntax vs bash syntax, leading to commands like:

# AI Generated (Incorrect for PowerShell)
cd coding-agent && mkdir agents mcp-servers sdk-implementations

Instead of:

# Correct PowerShell Syntax
cd coding-agent; mkdir agents, mcp-servers, sdk-implementations

2. Misleading Tool Description

Problem: The tool parameter description states:

"The command to run. This will be passed directly into the IDE shell."

Issue: This suggests commands should be written for a generic "IDE shell" rather than explicitly stating they need to be PowerShell-compatible on Windows.

3. Implementation vs Documentation Mismatch

Implementation (Correct): core/tools/implementations/runTerminalCommand.ts

function getShellCommand(command: string): { shell: string; args: string[] } {
  if (process.platform === "win32") {
    // Windows: Use PowerShell
    return {
      shell: "powershell.exe",
      args: ["-NoLogo", "-ExecutionPolicy", "Bypass", "-Command", command],
    };
  }
  // ...
}

Problem: The AI isn't explicitly told that on Windows, commands will be executed via PowerShell with these specific arguments, causing it to generate bash-compatible syntax.

4. Missing PowerShell-Specific Guidance

The system message lacks examples showing critical syntax differences:

Operation	Bash Syntax	PowerShell Syntax
Multiple Commands	command1 && command2	command1; command2
Directory Navigation	cd folder && pwd	cd folder; pwd
Path Handling	./folder	.\folder or folder
Create Multiple Dirs	mkdir dir1 dir2 dir3	mkdir dir1, dir2, dir3
Environment Variables	$HOME	$env:USERPROFILE

Specific Command Failures

Directory Navigation Issue

# What AI Generated (Bash Style)
cd coding-agent && pwd

# What PowerShell Received
cd coding-agent && pwd  # && is not recognized in PowerShell

# What Should Have Been Generated
cd coding-agent; pwd

Directory Creation Issue

# What AI Generated
mkdir agents mcp-servers sdk-implementations

# PowerShell Behavior
# Created all directories in current location instead of relative to cd

# What Should Have Been Generated
New-Item -ItemType Directory -Path agents, mcp-servers, sdk-implementations
# OR
mkdir agents, mcp-servers, sdk-implementations

Path Resolution Issue

# What AI Generated
cd coding-agent
mkdir ./agents ./mcp-servers

# PowerShell Issue
# ./ is not standard PowerShell path syntax

# What Should Have Been Generated
cd coding-agent
mkdir agents, mcp-servers

The Root Problem

The AI generated bash-style commands because:

1. Generic Platform Info: The tool description is generic rather than prescriptive
2. No Syntax Examples: System message lacks PowerShell-specific command examples
3. Cross-Platform Confusion: No explicit warning about syntax differences between shells
4. Implicit Assumptions: AI assumes POSIX-style shell behavior universally

Recommended Solution

The tool definition should include explicit PowerShell syntax guidance when running on Windows:

const POWERSHELL_GUIDANCE = `
CRITICAL: On Windows, commands are executed via PowerShell. Use PowerShell syntax:
- Multiple commands: use semicolons (;) not && or ||
- Paths: use backslashes or forward slashes, avoid ./
- Create directories: mkdir dir1, dir2, dir3 (comma-separated)
- Variables: $env:VARIABLE not $VARIABLE
`;

This would prevent the mixed syntax issues that caused the directory setup failures.

[PierrunoYT]

Based on the analysis, the main file that needs to be edited is:

core/tools/definitions/runTerminalCommand.ts

This file contains the tool definition that generates the system message instructions for the AI. Specifically, these sections need modification:

Current Problematic Code:

const PLATFORM_INFO = `Choose terminal commands and scripts optimized for ${os.platform()} and ${os.arch()} and shell ${getPreferredShell()}.`;

const RUN_COMMAND_NOTES = `The shell is not stateful and will not remember any previous commands.\
      When a command is run in the background ALWAYS suggest using shell commands to stop it; NEVER suggest using Ctrl+C.\
      When suggesting subsequent shell commands ALWAYS format them in shell command blocks.\
      Do NOT perform actions requiring special/admin privileges.\
      ${PLATFORM_INFO}`;

What Needs to Be Added:

1. Platform-specific syntax guidance
2. PowerShell-specific examples
3. Common command translations
4. Explicit warnings about cross-platform differences

Proposed Changes:

The PLATFORM_INFO and RUN_COMMAND_NOTES constants should be enhanced with PowerShell-specific guidance when os.platform() === "win32".

Secondary File (Optional Enhancement):

core/tools/implementations/runTerminalCommand.ts

Could potentially be enhanced to provide better error messages when commands fail due to syntax issues, but the primary fix needs to happen in the definitions file where the AI instructions are generated.

Why This File?

This is the source of truth for:

• Tool parameter descriptions
• System message content that instructs the AI
• Platform detection logic
• Examples provided to the AI

By fixing the instructions in this file, the AI will generate proper PowerShell syntax from the start, preventing the directory navigation and command chaining issues you experienced.
