Use this subagent PROACTIVELY — don't wait for the user to ask for delegation — whenever a task contains a well-scoped, ABOVE-break-even unit of work for the Antigravity CLI (agy / Gemini): bulk scaffolding, exhaustive test generation, migrations, long-context reads that distill to a digest, or fan-out web / Vertex AI…
Delegates code analysis, large-file analysis, and adversarial review tasks to agy (Google Antigravity CLI) using Gemini Pro. Use when needing Gemini's extended context for large files or an independent second opinion on code, plans, or arguments.
Delegates web search and research tasks to agy (Google Antigravity CLI). Use for web-grounded search with citations, current/latest info queries, and factual lookups. Read-only — no file editing.
Hand a task the user has asked to give to Gemini or AGY -- investigation, diagnosis, a second implementation pass, or a substantial coding task -- to the shared companion runtime. Use only when the user has asked for Gemini or AGY.
End-to-end research-to-spec workflow. Takes raw user research and produces a complete Feature Request with persona context — running synthesize-user-research, build-user-persona, and write-feature-request in sequence. Use when you have research data and want to go straight to a finished FR without managing each skill…
Feature-request-to-dev-ready workflow. Takes a raw feature idea or existing FR through authoring, AC verification, and engineering handoff — running write-feature-request, verify-acceptance-criteria, and write-technical-brief in sequence. Use when you want a complete, dev-ready handoff package in one session. Trigger…
Full sprint-to-communications workflow. Takes sprint data and produces all three stakeholder artefacts — running sprint-review, write-release-notes, and write-stakeholder-update in sequence. Use at the end of every sprint to produce the complete communication package in one run. Trigger on: "run…
Writes tests for existing behaviour. Adds and edits test files only — never touches production code. Use for coverage backfill where the bulk of the work is mechanical.
Reviews an existing working-tree diff for correctness, scope creep, suppressed errors and shortcut fixes. Reports findings only — never edits. Use as a second opinion before the driver accepts a worker's changes.
Read-only surveyor. Maps a repository's architecture, entry points, dependencies, test commands and risky areas without modifying anything. Use before any implementation work so the driver can scope a task accurately.
