Agy Native

AGY Native

Run a supplied packet in AGY (Antigravity) only when the caller explicitly selects that runtime. Scope the run to the supplied workspace and packet, return runtime evidence, and stop.

Before launch

1. Read the live surface. Run agy --help for flags and defaults and agy models for the current model set. The CLI changes faster than skill text. Wrapper drift is a run built from remembered syntax that silently changed: it looks scoped and is not.
2. Absent means stop. If agy is missing or its help cannot be read, report the absence and stop. Never fall back silently to Codex, Claude or any other runtime; a substitute needs a new caller selection. Nothing routes work to AGY on its own either. The repository reviewer library rates AGY a routine-tier, degraded-fallback reviewer; that rating applies only when a caller opts in, and it is not an automatic route.
3. Set an explicit bound. Print mode (agy -p / --print) is the headless path, and it has no built-in limit: --print-timeout defaults to 0, which waits until the turn completes (AGY 1.2.14). Pass --print-timeout from the caller's remaining deadline and hold the same bound outside the process. A run stopped at the bound is a timeout, not a result.
4. Name the posture (below) and confirm the packet's declared effects and the caller's authorization cover it.
5. Keep author and validator apart. A validator is a new run in a new conversation, never -c/--continue or --conversation <author-id>. A session that reviews its own work forfeits the fresh judgment that makes a validator's evidence usable. Validators stay read-only and hand judgment to Validate; they never write the core verdict.

Permission posture (disclose it; never assume it)

Flags choose the posture. Name the one used:

• No posture flag: AGY prompts for each tool permission. A headless run has no one to answer, so a prompt can stall it until the bound.
• --dangerously-skip-permissions: auto-approves every tool call. Use it only when the declared effects and the caller's authorization cover that blast radius.
• --sandbox: restricts the session's terminal access.
• --mode (plan, accept-edits): changes the execution mode; confirm its current meaning in agy --help.

Command

Every agy flag below appears in agy --help for AGY 1.3.1; recheck before use. DEADLINE_EPOCH is an absolute Unix time the caller fixes once and reuses for every run in its scope, so a second run gets what is left rather than a new bound. POSTURE is a Bash array of the posture flags chosen above, for example POSTURE=(--sandbox); an empty array means AGY asks for each tool. PROMPT_FILE is an absolute path. The packet goes by path, not inline: a short -p pointer plus --add-dir, as scripts/lib/codex-exec.sh does, because a large inline prompt can be dropped while the run still looks scoped.

bashCopy code
TO=$(command -v timeout || command -v gtimeout) || { echo "no timeout: not launching" >&2; exit 2; }
remaining=$(( DEADLINE_EPOCH - $(date +%s) ))
[ "$remaining" -gt 0 ] || { echo "deadline passed; not launched" >&2; exit 124; }
cd "$WORKSPACE" || exit 2
"$TO" -k 10 "$remaining" \
  agy --print-timeout "${remaining}s" --model "$MODEL" --output-format json \
  "${POSTURE[@]}" --add-dir "$(dirname "$PROMPT_FILE")" \
  -p "Read the task packet at $PROMPT_FILE and do what it describes." >"$OUT" 2>"$ERR"
rc=$?  # 124, or 137 after the 10 s grace: the outer bound stopped the run

--print-timeout takes a duration with a unit, such as 300s. Add flags before -p so none lands after the prompt text. AGY's help does not say which status it returns when its own print timeout fires, so a run that ends at the bound is a timeout unless its output shows a finished turn.

Return

textCopy code
command:      exact argv (prompt by reference)
posture:      permission, sandbox and mode flags used
model:        requested model; observed model if AGY reported one, else unknown
conversation: id AGY reported, else unknown
bound:        --print-timeout value and the outer deadline
outcome:      exit status | timed out | not run (reason)
artifacts:    captured output and changed-file paths

AGY plugin, memory, permission, retry and session state are runtime facts; they never become AgentOps phase, queue or completion state. Installation, plugin mutation and recurring scheduling need separate explicit authorization.
