Attribution fields like agent, skill, plugin, and MCP names can now be redacted from emitted metrics

What

Claude Code can now redact certain attribution fields before sending out metrics: agent.name, skill.name, plugin.name, mcp_server.name, and mcp_tool.name. The first time one of these values would differ from a shared baseline, it gets replaced with a common placeholder value instead, unless a setting allows the real, unredacted values to be sent.

Why

This limits how much identifying detail about which agents, skills, plugins, or MCP tools you use gets included in emitted metrics, when the corresponding setting isn't enabled.

Feature flag
tengu_teal_corbel_newel Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.273: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
