the ide is becoming the gatekeeper for agent output. rider now ships quality-check hooks that validate every change from claude code and codex before a task can be marked done, blocking on code issues and even formatting drift.
the review humans were too slow to do is getting automated inside the editor.
Context
JetBrains' Rider 2026.2 EAP 5 post of 8 June 2026 describes quality-check hooks for Claude Code that validate every change an agent makes before it can continue, catching code issues, inspection findings and formatting inconsistencies; errors block the task from being marked complete and warnings come back as feedback. The setting is under Tools | AI Agent Hooks. The post said Codex support is coming. A snippet of the 22 July 2026 release post lists the hooks for Claude Code.
The hooks are first-party and date from a June early-access build and the July release, not from September. Codex was described as coming in June; no source read shows it shipped by 20 September 2026, and absence in the July snippet is not proof it did not. Every change and formatting are JetBrains' wording. That the IDE is becoming the gatekeeper, and that humans were too slow to review, are the author's arguments.
Watch next
- Whether Codex support shipped, and behavior in stable builds.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
