Claude Code v2.1.92 — 5 New Environment Variables: Proxy Simulation, Fast Mode Bypass, and Remote Session Naming#

Published on April 3, 2026

Part of the Claude Code Version Tracker series. | Official Env Vars | Official Changelog

Claude Code v2.1.92 adds 5 new environment variables with no removals since v2.1.91. The additions cluster around enterprise deployment concerns: proxy testing without proxy infrastructure, org-check bypasses for fast mode, and session naming conventions for remote automation. The changelog adds an interactive Bedrock setup wizard, per-model cost breakdowns for subscribers, and policy-enforced remote settings refresh — reinforcing that this release is tuned for teams managing Claude Code across organizations.

New Environment Variables#

VariableLikely Purpose
CLAUDE_CODE_SIMULATE_PROXY_USAGESimulates proxy-based API routing without an actual proxy. This is a testing tool — it lets developers verify that their Claude Code configuration behaves correctly when routed through a corporate proxy, without needing the proxy infrastructure in place. Useful for validating that authentication, headers, and request routing work correctly before deploying to a proxy-gated environment. Enterprise teams can pre-flight their configurations locally and catch proxy-related auth failures before rolling out to the whole organization.
CLAUDE_CODE_SKIP_FAST_MODE_ORG_CHECKDisables the organization-level eligibility check for fast mode. Fast mode (toggled via /fast) normally verifies that the user's organization supports it. This skip flag suggests enterprise environments where the org check fails due to proxy configurations or custom API routing, but fast mode should still be available. A pragmatic escape hatch for the gap between "our org has access" and "the check can reach the server to confirm it."
CLAUDE_REMOTE_CONTROL_SESSION_NAME_PREFIXSets a prefix for Remote Control session names. The changelog[1] mentions improved session naming for Remote Control — this variable lets teams enforce naming conventions for sessions spawned via remote automation, making them identifiable in logs and dashboards. A CI system might prefix sessions with ci- or a team name to distinguish automated from interactive sessions. Essential for organizations running dozens of concurrent remote sessions where "claude-session-abc123" is meaningless without context.
CLAUDE_CODE_EXECPATHOverrides the detected executable path for the Claude Code binary. This matters in environments where the binary is symlinked, wrapped in a shell script, or installed in a non-standard location. Downstream features like auto-update, version detection, and the /doctor diagnostics need to know the true binary path, and this variable provides an explicit override when auto-detection fails.
CLAUDE_BASELikely overrides the base URL or base configuration path for Claude Code. This is a compact alternative to the more specific CLAUDE_CODE_API_BASE_URL — potentially used internally or as a shorthand for environments where a single base path controls both API routing and local configuration resolution.

What These Tell Us#

Enterprise deployment friction is the target. Three of five new variables — proxy simulation, fast mode org check bypass, and session name prefixes — address the gap between "Claude Code works on a developer's laptop" and "Claude Code works behind our corporate proxy with our IAM setup at scale." The SIMULATE_PROXY_USAGE flag is particularly telling: Anthropic is building testing tools for environments they can't directly access. Rather than asking enterprise customers to debug proxy issues in production, this flag lets IT teams reproduce and validate proxy behavior locally. It's the kind of feature that only exists because enough customers hit the same class of deployment problem.

Remote Control is maturing into a managed service. Session name prefixes sound mundane, but they signal that Remote Control is being used in contexts where observability matters — CI/CD pipelines, automated code review bots, and multi-team deployments where you need to know which system spawned which session. Combined with the policy-enforced remote settings refresh announced in the changelog, Remote Control is moving from "a way to control Claude Code remotely" to "an orchestration primitive that enterprises can govern."

The Bedrock wizard is the headline, but the env vars tell the real story. The changelog leads with the interactive Bedrock setup wizard, but the environment variables reveal the operational layer beneath it. SKIP_FAST_MODE_ORG_CHECK and SIMULATE_PROXY_USAGE exist because the wizard's happy path doesn't survive contact with every enterprise network topology. These escape hatches are the unglamorous work that makes Bedrock adoption actually work at scale.
