A coding agent becomes more capable when it can edit files, run commands and reach external services. The same permissions also increase the cost of a mistaken instruction, compromised dependency or misleading page.
Read access and write access should be considered separately. Many diagnosis tasks require inspection but do not require changing files or external state.
Prefer service credentials with narrow scopes and short lifetimes. A deployment token should not also provide billing administration or access to unrelated repositories.
Full access may be convenient for a controlled maintenance window, but it should not become the permanent default for routine coding tasks.
Begin with the smallest workspace
Give the agent access only to the repository or project needed for the task. Keep personal folders, credential stores and unrelated projects outside that boundary. Use a separate test environment when production configuration is present.Read access and write access should be considered separately. Many diagnosis tasks require inspection but do not require changing files or external state.
Gate sensitive actions
Require explicit approval for package installation, network transmission, permission changes, production deployment and destructive commands. Store secrets in the environment or a secret manager rather than in prompts, logs or source files.Prefer service credentials with narrow scopes and short lifetimes. A deployment token should not also provide billing administration or access to unrelated repositories.
Keep changes reviewable
Ask the agent to work in small commits or clear diffs, run relevant tests and report remaining uncertainty. Preserve logs for important automated operations without recording secrets.Full access may be convenient for a controlled maintenance window, but it should not become the permanent default for routine coding tasks.
