This pull request introduces significant changes to the ElizaOS CLI's handling of Bun installation and command execution. The main updates involve replacing the execa package with custom Bun-based utilities (bunExec, bunExecSimple, and bunExecInherit) to improve compatibility and streamline operations. Additionally, enhancements were made to the Bun installation workflow and related utilities.

Bun command execution updates:

Added bun-exec.ts with custom utilities (bunExec, bunExecSimple, bunExecInherit) to replace execa for executing commands using Bun's shell functionality. These utilities provide better integration with Bun and support options like cwd, env, and stdio.
Updated auto-install-bun.ts to use bunExec and bunExecInherit for checking Bun installation and executing installation scripts. This improves reliability and removes direct dependencies on execa.
Replaced execa with bunExecSimple in user-environment.ts for fetching Bun and npm versions, ensuring consistency across the CLI. [1] [2] [3]

Bun installation workflow improvements:

Refactored bun-installation-helper.ts to use commandExists from bun-exec.ts for checking Bun availability and added structured BunInstallationResu 8000 lt for clearer installation status reporting.
Simplified installation tips and instructions in bun-installation-helper.ts to provide concise, platform-specific guidance for installing Bun.

Dependency cleanup:

Removed the execa package from package.json as it is no longer needed, reducing external dependencies.

ElizaOS PR Review: Remove execa for bun.Spawn

Review Checklist:

Read and analyze all changed files
Security review of process execution changes
TypeScript type safety verification
Test coverage analysis
ElizaOS architecture compliance check
Monorepo compliance verification
Documentation requirements assessment
Provide comprehensive review feedback

🔴 CRITICAL ISSUES

1. MISSING TEST COVERAGE - CODE IS LIKELY BROKEN

Severity: CRITICAL
Issue: The new bun-exec.ts utility has NO test coverage
Impact: Following ElizaOS guidelines, "CODE WITHOUT TEST COVERAGE IS PROBABLY BROKEN"
Files: packages/cli/src/utils/bun-exec.ts (133 lines of untested code)
Required Action: Comprehensive test suite must be created covering:
- Success scenarios for bunExec(), bunExecSimple(), bunExecInherit()
- Error handling and edge cases
- Cross-platform compatibility (commandExists())
- Argument escaping and command construction
- Process output handling

2. SECURITY VULNERABILITIES IN PROCESS EXECUTION

Severity: CRITICAL
Issue: Potential command injection vulnerability in argument escaping
Location: packages/cli/src/utils/bun-exec.ts:30-36

Problem: The argument escaping logic is insufficient:

if (arg.includes(' ') && !arg.startsWith('"') && !arg.endsWith('"')) {
  return `"${arg}"`;
}

Vulnerability: Does not escape arguments containing quotes, semicolons, or other shell metacharacters
Example: bunExec('echo', ['hello"; rm -rf /']) could execute dangerous commands
Required Fix: Implement proper shell escaping using a secure escaping library

3. IMPROPER ERROR HANDLING

Severity: CRITICAL
Issue: Error handling inconsistencies and potential crashes
Location: packages/cli/src/utils/bun-exec.ts:52-60
Problems:
- No error handling for new Response(proc.stdout).text() if streams are null
- proc.stdout and proc.stderr could be null but are used without proper checks
- Generic catch block at line 80 rethrows errors without proper context

🟠 IMPORTANT ISSUES

4. TYPESCRIPT TYPE SAFETY VIOLATIONS

Severity: IMPORTANT
Issue: Missing proper TypeScript typing
Location: packages/cli/src/utils/bun-exec.ts:97
Problem: Uses any type in error handling: (error as any).exitCode
Fix: Define proper error interface extending Error with exitCode and stderr properties

5. INCONSISTENT ARCHITECTURE PATTERNS

Severity: IMPORTANT
Issue: The new utility doesn't follow ElizaOS architectural patterns
Problems:
- Direct process execution without proper service abstraction
- No integration with existing logging/monitoring systems
- Hardcoded shell commands without configuration options

6. INCOMPLETE PROCESS MANAGEMENT

Severity: IMPORTANT
Issue: No process cleanup or timeout handling
Location: packages/cli/src/utils/bun-exec.ts:63
Problems:
- No timeout mechanism for long-running processes
- No process cleanup on errors
- No signal handling for process termination

🟡 SUGGESTIONS

7. LOGGING IMPROVEMENTS

Severity: SUGGESTION
Issue: Inconsistent logging patterns
Location: Multiple files
Problems:
- Debug logging should use structured logging format
- Missing correlation IDs for tracking related operations
- No performance metrics for process execution

8. CROSS-PLATFORM COMPATIBILITY

Severity: SUGGESTION
Issue: Platform-specific code could be improved
Location: packages/cli/src/utils/bun-exec.ts:123-128
Suggestion: Use cross-platform utilities or test coverage for Windows edge cases

✅ COMPLIANCE CHECKS

ElizaOS Architecture Compliance

✅ Uses @elizaos/core for logger imports
✅ Follows functional programming patterns
✅ No circular dependencies detected

Monorepo Compliance

✅ Successfully removes execa dependency
✅ Uses bun exclusively for package management
✅ Follows existing project structure

Code Style

✅ TypeScript usage (except for noted violations)
✅ Proper file organization
✅ Consistent naming conventions

📋 REQUIRED ACTIONS BEFORE MERGE

Create comprehensive test suite for bun-exec.ts utility
Fix security vulnerability in argument escaping
Add proper error handling for stream operations
Remove TypeScript any types and add proper interfaces
Add timeout and process cleanup mechanisms
Update documentation for the new utility functions

📝 DOCUMENTATION UPDATES NEEDED

The following documentation needs to be updated:

Add JSDoc comments for all public functions in bun-exec.ts
Update any CLI documentation that mentions process execution
Add security notes about shell command execution

🔄 RECOMMENDATION

DO NOT MERGE until critical security and testing issues are resolved. The concept of replacing execa with native bun.Spawn is sound, but the implementation has significant security vulnerabilities and lacks test coverage.

Priority Order:

Fix command injection vulnerability (CRITICAL)
Add comprehensive test coverage (CRITICAL)
Improve error handling (CRITICAL)
Address TypeScript type safety (IMPORTANT)
Add process management features (IMPORTANT)

🟡 REMAINING ISSUES TO ADDRESS

1. PATH Update Issue (Minor)

Issue: auto-install-bun.ts:41 - After Bun installation, PATH isn't updated in current process
Impact: Installation verification may fail even when successful
Location: packages/cli/src/utils/auto-install-bun.ts:41-51
Fix: Add function to update process.env.PATH after installation

Example:

function updatePathForBun(): void {
  const bunPath = process.platform === 'win32' 
    ? path.join(os.homedir(), '.bun', 'bin')
    : path.join(os.homedir(), '.bun', 'bin');
  
  if (!process.env.PATH?.includes(bunPath)) {
    process.env.PATH = `${bunPath}${path.delimiter}${process.env.PATH}`;
  }
}

2. Hardcoded Sleep Duration (Minor)

Issue: auto-install-bun.ts:41 - 2-second hardcoded sleep may be insufficient
Suggestion: Implement retry mechanism with exponential backoff
Impact: Installation verification might fail on slower systems

Comments suppressed due to low confidence (3)

packages/cli/src/utils/bun-installation-helper.ts:49

[nitpick] The naming of displayBunInstallInstructions and displayBunInstallationTipCompact is inconsistent and may confuse maintainers; consider renaming them to clearly reflect their separate purposes or consolidating into a single well-named API.

export function displayBunInstallInstructions(): void {

packages/cli/src/utils/auto-install-bun.ts:122

The removal of the --no-auto-install flag check in shouldAutoInstall may break existing user workflows that disable auto-install via CLI arguments; consider reintroducing or documenting this change as a breaking update.

  // Check if running in a container

packages/cli/src/utils/bun-installation-helper.ts:1

There are no tests covering the new checkBunInstallation, displayBunInstallInstructions, or displayBunInstallationTipCompact functions; adding unit tests for these helpers will improve coverage and guard against regressions.
