Agents that Little Spaces setup connects

Setup connects the coding agents below, the same list the Works with table on the Agents page shows. It finds each app by the folder or settings file the app keeps on your computer, and installs only for the apps your approval names. This page lists what works in each app, any one-time step, and how your answers reach its sessions.

What works in each

The What works column uses the Agents page’s words:

Runs, reports and answers: sessions show under Runs, report milestones and ask you questions, and your answers reach them.
Runs and reports; it checks for answers: sessions show under Runs and report, and the agent fetches your answers itself.
Reports; it checks for answers: the app has no automatic hooks. Instructions tell each session to start a run, report milestones and fetch your answers.

Agent	What works	One-time step	Seen working in a real session
Claude Code	Runs, reports and answers	None	Yes
Codex	Runs, reports and answers	Codex asks once to trust new or changed hooks: approve them when it does, or Codex sessions will not show under Runs.	Yes
Cursor	Runs, reports and answers	None	Not yet
Gemini CLI	Runs, reports and answers	Gemini CLI loads hooks when it starts: restart each Gemini CLI session that is running now, or it will not show under Runs.	Not yet
Copilot CLI	Runs, reports and answers	None	Not yet
Devin	Runs, reports and answers	Devin loads no hooks in Restricted Mode: its sessions show under Runs only outside it.	Not yet
Grok Build	Runs, reports and answers	Grok Build loads new hooks when a session starts: in a Grok Build session that is running now, open `/hooks` and press `r` to reload them.	Not yet
Muse Code	Runs, reports and answers	Muse Code loads hooks only when a session starts: start a new Muse Code session for it to show under Runs.	Not yet
Antigravity	Runs, reports and answers	Antigravity may read new hooks only when a conversation starts: start a new Antigravity conversation for it to show under Runs.	Not yet
Goose	Runs, reports and answers	None	Not yet
OpenCode (v2 only)	Runs, reports and answers	None	Not yet
Pi	Runs, reports and answers	Pi loads extensions when a session starts: in a Pi session that is running now, run `/reload` for it to show under Runs.	Not yet
Amp	Runs, reports and answers	Amp loads plugins when it starts: in an Amp that is running now, run its `plugins: reload` command, or restart it, for its threads to show under Runs.	Not yet
Cline	Runs and reports; it checks for answers	Cline runs hooks only while its Enable Hooks setting is on: check it under Feature Settings in Cline, or its tasks will not show under Runs.	Not yet
Aider	Runs and reports; it checks for answers	Aider reads its config when it starts, and asks before it runs a shell command: in a new Aider session, let it run `spaces session start` when it asks, and add the output to the chat.	Not yet
Windsurf Cascade	Reports; it checks for answers	Cascade reads its global rules when a conversation starts: start a new Cascade conversation for it to report.	Not yet
Zed	Reports; it checks for answers	None	Not yet

“Not yet” means the connection was built from the app’s documentation and hasn’t been seen working in a real session yet. The Agents page and setup’s summary say the same. For OpenCode, setup installs only for OpenCode v2. For OpenCode v1, or a version it can’t tell, it installs nothing and says so.

How your answers reach each one

Agent	How answers arrive	Can wake an idle session
Claude Code	A background hook wakes the session when an answer comes within 15 minutes of a turn’s end; otherwise with your next message.	Yes
Codex	The end-of-turn hook continues the turn when an answer arrives; otherwise with your next message.	No
Cursor, Copilot CLI, Grok Build, Muse Code, Goose	The end-of-turn hook continues the turn when an answer arrives.	No
Gemini CLI, Devin	The end-of-turn hook continues the turn when an answer arrives; otherwise with your next message.	No
Antigravity	The end-of-turn hook continues the turn when an answer arrives.	No
OpenCode v2, Pi	With your next message. While the session is idle, Little Spaces’ plugin wakes it with an answer that comes up to two hours after its turn ended.	Yes (not yet seen in a real session)
Amp	With your next message, or the end of the turn continues when an answer arrives. Nothing wakes an idle thread.	No
Cline, Aider, Windsurf Cascade, Zed	The agent fetches answers itself.	No

An end-of-turn hook waits for an answer for five minutes by default, and only while a question or approval from the session is open. An answer that comes later reaches the session as the table says, or when the agent next fetches its answers.

The session you paste the prompt into

That session started before its hooks existed, so setup connects it directly when it can tell which session it is, and it shows under Runs straight away. Some apps load new hooks only in a new session; setup’s summary says when to start one, and the pasted session stays live through its own reports until then.

An agent that isn’t listed

An agent setup doesn’t connect can still connect itself. Setup points it to spaces connect --help, which prints a short guide for the agent to follow. The agent shows you the exact change first, makes it only in its own user-level files, and writes no credential. Its sessions then show under Runs, or report and fetch your answers, under a name it chooses. Hosted assistants, which run on their vendor’s servers, connect differently: see hosted assistants.
