TL;DR: Coding agents become an authorization problem when they can act inside repositories, terminals, APIs, and CI/CD workflows, according to PermitIO. Per-tool policy has to replace broad inherited access so delegated tasks do not inherit more privilege than they need.
Editorial analysis by NHI Mgmt Group, based on content published by PermitIO: “Securing Coding Agents: What You Need to Know”.
Key questions
Q: Why do coding agents need per-tool authorization instead of session-wide permissions?
A: Session-wide permissions ignore that a coding agent may read files, run tests, edit code, and touch CI/CD systems within the same task.
Q: What are the signs that a coding agent is overprivileged?
A: A coding agent is overprivileged when it can reach high-impact actions that are not required for the task, such as protected branch merges, production deploys, inbox access, package publishing, or secret reads.
Q: What breaks when coding agents inherit a developer's full access?
A: Shared developer access breaks the assumption that a task-specific agent only needs the same authority as a human operator.
Practitioner guidance
- Separate agent authority from developer authority Give coding agents permissions that match the delegated task, not the human’s full repository, cloud, or CI/CD access.
- Enforce tool-call authorization in front of MCP and similar integrations Authorize each invocation using the delegating user, task scope, target resource, and requested action before the tool executes.
- Classify repository text as untrusted input Treat README files, comments, issue bodies, docstrings, and changelogs as possible instruction carriers when an agent is reading a codebase.
Bottom line: Coding agents create an authorization problem because they can act inside repositories, terminals, APIs, and CI/CD workflows, not just generate suggestions.

Tool-level authorization is now the decisive control plane for coding agents: the old assumption that a developer’s access can safely be inherited by an agent no longer holds. A coding agent executes actions, not just suggestions, so the security boundary must move to the tool call itself. The implication is that authorization has to become contextual, not session-based.
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 security teams govern coding agents that can execute repository instructions?
A: Treat repository instruction files as executable input, not documentation. Review AGENTS.md and similar artefacts before unsupervised execution, scan them for shell commands and credential-path access, and enforce allow or block decisions outside the model. The control objective is to prevent untrusted repository content from becoming trusted pre-task execution.
