Keeping credentials out of your coding agent’s model context

Описание и применение

ContextVeil удаляет выбранные секреты из вывода кода, предотвращая их утечку в модели, при этом не блокируя доступ к файлам.

Задача

Coding agents often read files containing credentials, risking accidental exposure of secrets in their model context.

Результат

ContextVeil successfully removes selected secret values from agent output, reducing accidental credential exposure without blocking legitimate file reads or commands.

Рабочий процесс

• 1. Install ContextVeil via the provided shell script.
• 2. Run contextveil setup in the project directory to review and select secrets to protect.
• 3. Integrate ContextVeil with the chosen coding agent (e.g., Claude Code) by approving the hook.
• 4. Use the coding agent as usual; ContextVeil automatically sanitizes output before it reaches the model.
• 5. Run contextveil doctor to verify the integration and troubleshoot if needed.

Доказательства
