TL;DR: The boundary shifts when coding-agent tasks leave the workstation for a cloud session, according to Dash Security. Endpoint EDR, telemetry, and monitoring can miss the handoff, so runtime oversight has to follow the task path.
Editorial analysis by NHI Mgmt Group, based on content published by Dash Security: “Sleeper Skills: Evading Endpoint Security Through Cloud Coding Agents”.
Key questions
Q: Why do sleeper skills create a greater risk than ordinary malicious prompts?
A: They separate intent from trigger.
Q: How should security teams detect malicious behaviour inside cloud coding agents?
A: They should correlate repository context, runtime environment signals, and downstream credential or file-access behaviour.
Q: What breaks when coding-agent tasks move from the endpoint to a cloud session?
A: Endpoint-only monitoring stops being a complete control surface.
Practitioner guidance
- Map execution boundaries for coding agents Document where tasks can run locally, in provider-managed cloud sessions, and on customer-managed workers so monitoring does not stop at the developer laptop.
- Inspect repository skills for environment-based branching Review project setup skills and similar context files for logic that changes behaviour when a cloud environment is detected instead of a local one.
- Extend detections beyond endpoint telemetry Correlate endpoint events with cloud-session activity, credential use, and repository actions so a malicious branch can be seen after the task moves off the workstation.
Bottom line: Cloud coding agents create a distinct governance boundary because endpoint controls do not automatically travel with the task into provider-managed or remote execution.

Cloud session drift creates a visibility gap, not just a new deployment model. The article shows that developer endpoint controls can be effective and still miss malicious behavior once execution moves into a cloud worker or provider-managed session. That means the practical security boundary is no longer the laptop; it is the handoff between execution zones. Teams should treat agent runtime location as a first-class governance variable, not an operational detail.
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: What is the difference between endpoint security and agent runtime governance for coding agents?
A: Endpoint security protects the workstation and its local execution context. Agent runtime governance follows the task into cloud sessions, workers, and other environments where the same skill or prompt can behave differently. For coding agents, both matter, but only runtime governance covers the full execution path.
