Commands

Updated 2026-10-21

On this page

The command for each task, in each harness. Pick what you are working with, then read across: commands you type in your shell or a script and commands you type inside an open session are listed separately. Commands for renaming sessions are on Thread naming and importing from another harness on Migration.

From your shell

Commands you run in a terminal or script, outside a session.

Notes and sources

Codex CLI

The shell CLI installs and removes plugins but has no enable, disable, update or validate command; the /plugins browser can switch plugins on or off.
--worktree starts new sessions in a managed Git worktree and works with codex fork given an explicit session; resume, queue, archive, unarchive and delete reject it at run time.
MCP protocol capabilities are recorded in mcp.json; these records cover the operator commands.

Claude Code

Some plugin authoring and evaluation commands are newer than the public reference, so each command keeps its live help evidence.
Plugin installs that run a marketplace-declared command need --accept-command <sha256> without a TTY.
Interactive commands are recorded separately from their shell equivalents.
2.1.304 adds /auto-mode-setup across Bedrock, Vertex, Foundry, Claude apps gateway and telemetry-disabled sessions; help output was corrected for several flags, and plugin validate no longer predicts where mod hooks run. Existing command help observations retain their versions.
claude plugin can also be written claude plugins.

Cursor Agent

Nested --help at this version prints the top-level help, so subcommand syntax for plugin marketplaces and in-session commands comes from the docs and changelog.
agent env, agent cloud and agent automations exist behind feature flags and are not recorded.

OpenCode 2.x

@opencode/cli 2.x runs one shared background service per user, managed with opencode service. Session sharing is not supported yet.
2.1 restores archiving through client.session.update({ sessionID, archived: true|false }) and archive filtering in client.session.list. These are SDK/HTTP operations, not newly claimed shell subcommands.
2.1 adds editable saved-grant action/resource patterns through client.permission.saved.update / PATCH /api/permission/saved/:id. Action is a tool/action name, not an allow/deny effect.
2.1.1 fixes provider reasoning variant generation after package normalization; other command observations retain their earlier help/source versions.

Shell MCP commands always use the built-in MCP and do not load extensions. In-session behaviour is documented, not live-probed.
