Claude Code v2.1.148 hotfix restores Bash tool after exit-code-127 regression

The regression itself was severe: every Bash invocation through the Claude Code tool returned exit code 127 (command not found), effectively bricking agentic coding sessions that relied on shell execution. v2.1.148 reverts the broken behavior and restores normal command resolution. The incident is a reminder that Claude Code has quietly become production developer infrastructure — when it breaks, real workflows break.

Claude Code lead Boris Cherny used the week to also tease the next version: a `/usage` command that breaks down token consumption by Skill, Agent, MCP and Plugin — CLI first, Desktop next. That's a direct response to the most-asked enterprise question of 2026: 'where are my tokens actually going?' as agentic stacks proliferate.

Context: a 1,648-upvote r/ClaudeAI post from a decade-experienced engineer described vibe-coding all side projects from their phone via Claude Code without reading any of the code — a vivid illustration of how dependent power users have become. Anthropic's parallel announcement of self-hosted sandboxes and MCP tunnels for Managed Agents (covered separately) makes Claude Code's tool layer increasingly viable for enterprise codebases where Bash execution touching real infra is the norm.

What to watch: the /usage rollout and whether Anthropic publishes a postmortem on the 127 regression — given Karpathy's arrival on the pretraining side and KPMG's 270,000-employee rollout, reliability now matters as much as capability.
