Claude Code Undocumented Other

Some parts of Claude Code fit no other area, such as modding, agent teams, and the status line. The official docs do not name the items below. Of its 64 rows, 54 are found only in the program, 7 differ from the docs, and 6 work only behind a flag or a gate. Anthropic can change or remove each item in any release.

Found Only in the Program

54 items are in the program but not in the official docs. These are the most useful ones.

• workflow-subagent: Agent used by Workflow scripts. See Subagents Runtime.
• InstructionFileKind: Tiers managed, user, project, local, memory. See Memory and Rules.
• comment-thread-analyst: Analyzes artifact comment threads. See Subagents Runtime.
• claude-code-github-action: The env var CLAUDE_CODE_ACTION is set. See Architecture.
• autoDreamEnabled: Background memory consolidation (auto-dream). See Memory and Rules.
• Log sinks: Sets the process title to claude and starts the log and telemetry sinks. See Architecture.
• main-session: Internal name for a main session run as a background task. See Subagents Runtime.
• Precomputed: A summary made ahead of time replaces the conversation. See Context and Compaction.
• Main action: Starts telemetry, starts SessionStart hooks (not on resume), checks forced login, and builds the app state. See Architecture.
• Plugin folders: Reads --plugin-dir, --plugin-dir-no-mcp, and --plugin-url. See Architecture.

Where the Docs Differ

7 items work in a different way from what the docs say. This is the whole list.

• autoMemoryDirectory scope: The schema says project settings are ignored. See Memory and Rules.
• next.error: In a .catch handler only. See Mod API Hooks.
• prompt.edit hook time: The docs say 50 milliseconds. See Mod API Hooks.
• vscode: The editor webview. Same table as desktop without Client. See Mod API UI Elements.
• hook type: "script": settings. See Probes.
• Model, fast mode, effort, thinking, and PR status change: Also re-run the command. See Status Line.
• disallowedTools: Denylist of tools. See Subagents Frontmatter.

Behind a Flag or a Gate

6 items work only when a flag or a gate is on. This is the whole list.

• Rollout switch: Bundle strings say installed hooks modules wait for a rollout flag, and a message says installed mods are turned off remotely. See Mod API Nouns and Gates.
• observer: Agent type auto-spawned as a background observer whenever this agent runs. See Subagents Frontmatter.
• observerMessage: Text appended to each activity digest sent to the observer. See Subagents Frontmatter.
• observeSubagents: Whether subagents inherit the observer. See Subagents Frontmatter.
• Agent teams: Several Claude sessions work as teammates. See Subagents Runtime.
• Teammate tools: Extra tools of a teammate. See Subagents Runtime.
