GitHub Copilot just shipped a real stop hook for agents, tightened CLI sandbox controls, and VS Code now shows what subagents are doing.
The Copilot SDK’s new agentStop lifecycle hook lets apps intercept the natural end of an agent turn and optionally keep it going, useful for enforced validation or retries; plus Rust gets startup timing breakdowns and Java can override tool param JSON schemas release notes.
Copilot CLI 1.0.76 brings enterprise-managed sandbox floors, stricter path-deny enforcement on macOS/Linux, smarter redirects in web_fetch, a Sessions sidebar, and a queue manager; it also adds grok-4.5 model support release.
VS Code 1.131 exposes live subagent model, runtime, and active tool details in the Agents window, with experimental dictation and a hybrid Markdown editor for agent workflows overview.
You can now enforce end-of-turn checks, validations, or retries without bolting on external orchestration.
Enterprise orgs get tighter, centrally managed CLI sandboxes to reduce accidental data exfil and unsafe fetches.
-
terminal
Wire agentStop to run final validation and auto-fix steps in staging; compare failure catch rates vs. today.
-
terminal
Enable a managed sandbox floor and try path-denied access and cross-origin web_fetch redirects to confirm prompts and policy behavior.
Legacy codebase integration strategies...
- 01.
Upgrade Copilot CLI to 1.0.76 and roll out org-managed sandbox; watch for breakages in scripts that rely on symlinks or relative paths.
- 02.
Adopt agentStop without disrupting long-running sessions; ensure continuation turns aren’t accidentally blocked.
Fresh architecture paradigms...
- 01.
Design agents with deterministic end-of-turn gates using agentStop and log each continuation for auditability.
- 02.
Use VS Code’s subagent view to debug tool usage and parallelism early in prototyping.
