How to Invoke

The user will ask something like:

"ask codex what it thinks about this code"
"get codex's opinion on this implementation"
"fais reviewer ce fichier par codex"

Execution

For file review (non-interactive)

codex exec "Review <file_path> and provide 3 specific improvements for production"

For bug analysis

codex exec "Analyze <file_path> for potential bugs and edge cases"

For dedicated code review

codex review

Note:

codex review

opens an interactive review session - use

codex exec

for non-interactive feedback.

Output Format

Present Codex's response clearly to the user. If Codex suggests improvements, summarize them as actionable items.

Examples

File review

User: "demande à codex de reviewer le benchmark"

codex exec "Review scripts/benchmark-semantic-router.py for improvements and potential issues"

Bug analysis

User: "ask codex to find bugs in this file"

codex exec "Analyze scripts/semantic-skill-router.py for potential bugs, edge cases, and error handling gaps"

Troubleshooting

Error	Cause	Fix
`codex: command not found`	CLI not installed	`npm install -g @openai/codex`
`Not authenticated`	Not logged in	Run `codex login`
`Model not available`	Account tier issue	Check ChatGPT subscription
Response timeout	Large codebase	Use specific file path, not whole repo
