Summary

Brings Google Antigravity CLI (agy) up to full agent parity in NodeTerm, measured against real agy 1.2.7 / 1.3.5 sessions and transcripts (~/.gemini/antigravity-cli/brain/<conversationId>/.system_generated/logs/transcript_full.jsonl and ~/.gemini/antigravity-cli/history.jsonl):

• Capabilities (src/shared/agents/config.ts):
  • Adds antigravity to CONTEXT_LINK_CAPABLE, CANVAS_CONTROL_CAPABLE, PERMISSION_MODE_CAPABLE, MODEL_SWITCH_CAPABLE, USAGE_CAPABLE, CHAT_CAPABLE + CHAT_LOCAL_ONLY, and TRANSFER_SOURCE_CAPABLE (while keeping CLAUDE_TRANSCRIPT_READABLE strictly ['claude']).
• Approval / Permission Modes (src/shared/agents/approval-mode.ts):
  • Maps plan -> --mode plan, acceptEdits -> --mode accept-edits, auto -> --mode auto, and bypassPermissions -> --dangerously-skip-permissions (manualIsDefault: true).
• Model Discovery & Switching (src/shared/agents/model-gateway.ts, src/main/index.ts, src/server/agent-status.ts):
  • Parses TSV output from agy models (<id>\t<Display Name>, including Gemini 4 Argon High/Medium, Gemini 3.1 Pro, Claude 4.6, GPT-OSS) via antigravityModelsFrom and routes modelsForAgent to Antigravity's own catalogue.
• Transcript Locator & Path Validation (src/core/handoff/locate.ts, src/core/claude-accounts-core.ts):
  • Implements locateAntigravity(sessionId) strictly keyed by sessionId under ~/.gemini/antigravity-cli/brain/<sessionId>/.system_generated/logs/ and allows ~/.gemini/antigravity-cli/brain in isSafeLocalTranscriptPath.
• Context Links (src/core/context-link-core.ts, src/core/context-link.ts, src/core/context-link-render.ts):
  • Parses USER_INPUT (<USER_REQUEST>), PLANNER_RESPONSE (assistant text + tool_calls), GENERIC (tool outputs), and ERROR_MESSAGE while ignoring SYSTEM_MESSAGE / CHECKPOINT.
• Context Window Meter (src/core/model-window.ts, src/core/antigravity-session.ts, src/core/context-ensure.ts, src/main/index.ts, src/server/agent-status.ts):
  • Computes live context usage from the latest PLANNER_RESPONSE (input_tokens + cache_read_tokens) and resolves model context windows via antigravityWindowFor (from <USER_SETTINGS_CHANGE> in turn 0 or hook modelName), wired in lockstep across desktop and Server Edition.
• Chat Panel (⌘M), Cross-Agent Handoff & Open Recent (src/core/antigravity-chat.ts, src/core/transcript-ipc.ts, src/main/handoff/render-antigravity.ts, src/core/recent-conversations.ts):
  • Adds paged/unpaged chat transcript reader, markdown handoff renderer, and recent conversations discovery combining brain/<id> with history.jsonl workspace paths.

Test Plan

• npm run typecheck
• npx vitest run src/core/antigravity.test.ts src/shared/agents/config.capabilities.test.ts src/shared/agents/approval-mode.test.ts src/shared/agents/model-gateway.test.ts src/shared/agents/launch.test.ts src/core/context-ensure.test.ts
• Validated end-to-end in a live packaged Windows build (0.4.2-antigravity) with two linked Antigravity 1.3.5 (Gemini 4 Argon) nodes exchanging messages (nodeterm.sh send / reply) and reading each other's transcripts via context.sh summary / terminal.
