What & why

Fixes #8906

agy (Antigravity CLI) is registered as a built-in terminal agent in @superset/shared (BUILTIN_TERMINAL_AGENTS), PRESET_ICONS, and the usage/quota readers, but had no entry in AGENT_SETUP_TARGETS or AGENT_SETUP_DEFINITIONS in @superset/agent-setup. As a result, no ~/.superset/bin/agy wrapper or lifecycle hooks were installed, leaving terminals running agy stuck in starting (No agent hook from this terminal yet) and causing superset agents wait to never return.

This change adds agy to @superset/agent-setup:

• Adds { id: "agy", managedBinary: true } to AGENT_SETUP_TARGETS and wires createAgyWrapper, createAgyHookScript, createAgyHooksJson, and removeAgyManagedHooks into AGENT_SETUP_DEFINITIONS.agy.
• Installs ~/.superset/bin/agy (agentId: "agy").
• Installs ~/.superset/hooks/agy-hook.sh and registers a managed superset-notify hook group in ~/.gemini/config/hooks.json covering SessionStart, PreInvocation, PostToolUse (matcher: ".*"), and Stop while preserving all other user hook namespaces on setup and teardown.
• In agy-hook.sh, prints {} to stdout as required by agy, guards execution to Superset terminals (SUPERSET_TERMINAL_ID / SUPERSET_TAB_ID) and SUPERSET_AGENT_ID=agy, maps PreInvocation to UserPromptSubmit and conversationId to session_id, skips Stop when fullyIdle is false, and forwards events to notify.sh with SUPERSET_HOOK_HARNESS=agy.

How I tested it

• Added 20 unit tests in packages/agent-setup/src/agent-wrappers-agy.test.ts covering wrapper creation, hooks.json setup/merge/teardown with existing user hook groups, and agy-hook.sh execution across SessionStart, PreInvocation, PostToolUse, Stop (fullyIdle: true and fullyIdle: false), foreign agents, and non-Superset terminals (bun test in packages/agent-setup: 423 pass, 0 fail).
• Ran bun run lint, bun run typecheck, and bun run check:plugins.
• Live end-to-end test in Paradev 2.0.0 with agy 1.4.7:
  1. Ran createAgyWrapper(), createAgyHookScript(), and createAgyHooksJson() to install ~/.superset/bin/agy, ~/.superset/hooks/agy-hook.sh, and the superset-notify group in ~/.gemini/config/hooks.json.
  2. Launched a live session via superset agents create --local --workspace <id> --agent agy --prompt "Say hello in one word".
  3. Sent a tool-calling follow-up turn via superset terminals send --text "Run echo hello-e2e using run_command" --wait --until idle --json and verified that agy transitioned through working -> ToolUse -> Stop (state: "idle", lastEventType: "Stop"), unblocking --wait as soon as the turn finished.

Summary by CodeRabbit

• New Features
  • Added setup support for Antigravity, including lifecycle notifications for session start, tool use, and other supported events.
  • Antigravity setup preserves unrelated hook settings and removes only its own managed hooks during teardown.

Walkthrough

The setup package adds AgY as a managed agent. It creates an AgY wrapper and lifecycle hook script, registers managed hooks in the Gemini hooks configuration, and removes those hooks during teardown.

Changes: AgY support

Layer / File(s)	Summary
Lifecycle hook forwarding packages/agent-setup/src/agent-wrappers-agy.ts, packages/agent-setup/templates/agy-hook.template.sh, packages/agent-setup/src/agent-wrappers-agy.test.ts	The hook script maps AgY lifecycle events and forwards selected events with the conversation ID. It skips forwarding when the required terminal context is absent, the agent identity does not match, the event is unknown, or a Stop event is not fully idle. Tests cover event mapping and filtering.
Managed setup and hook registration packages/agent-setup/src/agent-setup-targets.ts, packages/agent-setup/src/agent-setup.ts, packages/agent-setup/src/agent-wrappers-agy.ts, packages/agent-setup/src/agent-wrappers.ts, packages/agent-setup/src/agent-wrappers-agy.test.ts	AgY is added as a managed setup target. Setup creates its wrapper, hook script, and managed hooks in ~/.gemini/config/hooks.json; teardown removes the managed hooks while preserving other namespaces. Tests cover wrapper generation, hook configuration, and cleanup.

AgY lifecycle events can be attributed to the wrong conversation and lack the required workspace directory. Correct the hook payload before merging.

Full details: Out of Scope Changes check

Explanation

All changed files map to the agy setup objective of #8906: agent-setup-targets.ts (target registration), agent-setup.ts (definition wiring), agent-wrappers-agy.ts (wrapper, hooks.json managed group, hook-script install), agent-wrappers.ts (re-exports of the new helpers), templates/agy-hook.template.sh (hook adapter), and agent-wrappers-agy.test.ts (tests). No unrelated feature, refactor, or dependency change was identified in the reviewed summary. The whole-PR scope was evaluated against merge base e8babde. No previous reviewed head exists, so no incremental scope was used.

Full details: Linked Issues check

Explanation

Issue #8906 is the only active direct link. Most coding requirements are implemented at head 03251a9:

• AGENT_SETUP_TARGETS adds { id: "agy", managedBinary: true } (agent-setup-targets.ts).
• AGENT_SETUP_DEFINITIONS.agy wires createAgyWrapper, createAgyHookScript, createAgyHooksJson, and removeAgyManagedHooks (agent-setup.ts).
• createAgyWrapper sets agentId "agy" (agent-wrappers-agy.ts).
• The managed "superset-notify" group in ~/.gemini/config/hooks.json covers SessionStart, PreInvocation, PostToolUse (matcher ".*"), and Stop. Teardown preserves other namespaces.
• agy-hook.sh prints {} before any other work, maps conversationId to session_id, maps PreInvocation to UserPromptSubmit, skips Stop when fullyIdle is false, and passes SUPERSET_HOOK_HARNESS=agy to notify.sh.
• Unit tests exist in agent-wrappers-agy.test.ts.

Unmet requirement: the issue states that the hook payload's "workspacePaths" first element must be used as "cwd". agy-hook.template.sh reads only INPUT, conversationId, and fullyIdle. It never reads workspacePaths and never emits a cwd value. The payload it forwards is {"hook_event_name","session_id"} only. The downstream notify-hook.template.sh does not consume any cwd field either, so the mapping is absent end to end. The PR description does not mention this requirement.

Resolution

In packages/agent-setup/templates/agy-hook.template.sh, extract the first element of the "workspacePaths" array from INPUT, JSON-escape it, and include it as "cwd" in the payload piped to notify.sh. Add a unit test in agent-wrappers-agy.test.ts that feeds a payload with workspacePaths and asserts the forwarded cwd value. If the owner decides cwd is not needed downstream, the issue requirement must be amended by its author before this check can pass.
