TL;DR: Claude Code can write outside intended boundaries, read unexpected files, and affect pipelines when authorization lives in prompts or local configuration, according to Cerbos. Prompt-level trust is not a control plane for AI coding agents, and external enforcement is the missing governance layer.
Editorial analysis by NHI Mgmt Group, based on content published by Cerbos: “Your AI coding agents need guardrails. Not the kind you think”.
Key questions
Q: What breaks when Claude Code is allowed to govern its own permissions?
A: Prompt-level controls stop behaving like policy when the agent can interpret, stretch, or bypass the limits it is supposed to follow.
Q: Why do AI coding agents create a runtime authorization problem for IAM teams?
A: Because they can chain many tool calls from one user action, turning a simple session into a sequence of access decisions that humans cannot review in time.
Q: What do security teams get wrong about Claude Code hooks?
A: They often treat hooks as if they are governance by themselves.
Practitioner guidance
- Implement external tool-call authorization Route every Claude Code file read, write, and shell request through an external policy decision point before execution.
- Separate file, command, and secret scopes Define distinct rules for directory access, shell execution, and access to sensitive paths such as .env files or system locations.
- Centralise policy for all developer machines Use centrally managed settings so the hook that enforces runtime checks cannot be removed locally by the user or altered by the agent.
Bottom line: Claude Code becomes a governance risk when prompt-level trust is allowed to stand in for external authorization.

Prompt-level trust is not a control plane: This article exposes a governance model that assumes an AI coding agent will respect its own instructions. That assumption fails because the agent is both the actor and the interpreter of its limits, which makes prompt text too weak to serve as policy. The practitioner conclusion is that runtime enforcement must sit outside the agent process.
A few things that frame the scale:
- Claude Code-assisted commits leaked secrets at a rate of 3.2%, more than double the human-only baseline of 1.5%, with peaks reaching 31 secrets per 1,000 commits in August 2025, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How should organisations govern AI coding agents in the SDLC?
A: Treat them as privileged non-human identities with named owners, narrow task scope, and explicit offboarding. Governance should align access to the exact development activity, not to a broad team role or permanent environment trust. That is the difference between using the agent safely and leaving it as an unowned execution path.
