Overview ¶
Package antigravitycli implements the Antigravity model adapter. The CLI binary is `agy`. It is a full peer of the codex/claude adapters — reviewer, synthesizer, and input-budget setter.
Invocation ¶
agy is driven non-interactively via:
agy --print=- --print-timeout <dur> (prompt piped via stdin)
agy's `--print` is a string flag that REQUIRES a value (it is not a boolean toggle); `-` is the conventional stdin marker. When stdin is a pipe, agy reads the prompt from it, so prompts up to the 1 MiB input budget travel via stdin per ADR 0007 rather than argv (past ARG_MAX). Output is raw model text with no envelope, so stdout pipes directly into model.ParseFindings — unlike Gemini's `-o json`, which wrapped output in {"response": …}. There is no --output-schema flag, so JSON reliability is prompt-engineered (the same risk profile as codex without a schema), handled by the defensive parser.
Auth (S8b resolved) ¶
Spike S8b (2026-05-22) stubbed this adapter because agy v1.0.0 required interactive browser OAuth on every invocation. agy 1.0.9 fixed that ("Fixed OAuth token persistence and authentication hangs"), so tokens persist across calls and `agy --print` runs non-interactively once the user has logged in. Preflight only checks that `agy` is on PATH; a user who has never authenticated sees agy's own login prompt surfaced at Review time (the runner propagates stderr), matching codex/claude.

Constants ¶
const DefaultInputBudgetBytes = 1024 * 1024
DefaultInputBudgetBytes caps the prompt size sent to agy. Matches the codex/claude budget (1 MiB) so users get consistent behavior regardless of model choice. See codexcli for the underlying rationale.

Types ¶
type Adapter ¶
type Adapter struct {
// contains filtered or unexported fields
}
Adapter implements the model.Model interface against the Antigravity CLI (`agy`). agy 1.0.9 resolved the S8b auth blocker (persistent OAuth tokens), so this is a full peer: it reviews, synthesizes, and honors an input budget, matching the codex/claude adapters.
func New ¶
New constructs an Adapter. Passing nil uses provider.IsolatedRunner so agy can't onboard from the caller's cwd; lookPath defaults to exec.LookPath. Tests override fields directly (the package is internal-only).
func (*Adapter) Name ¶
Name returns the model identifier surfaced to users via the picker and attached to validated findings.
func (*Adapter) Preflight ¶
Preflight verifies the agy binary is on PATH. Auth failures (a user who has never run an interactive `agy` login) surface at Review time via agy's own stderr, which the runner propagates — matching codex/claude.
func (*Adapter) Review ¶
func (a *Adapter) Review(ctx context.Context, input *review.ReviewInput) (*review.ModelReviewResult, error)
Review invokes agy against the standard review prompt.
func (*Adapter) SetInputBudget ¶ added in v0.3.0
SetInputBudget overrides the default prompt-size cap. Values <= 0 are ignored so an unset --input-budget flag can't silently disable enforcement and let an arbitrarily large prompt slip through.
func (*Adapter) Synthesize ¶
func (a *Adapter) Synthesize(ctx context.Context, input *review.ReviewInput, results []*review.ModelReviewResult) (*review.ModelReviewResult, error)
Synthesize runs agy against the synthesis prompt that combines the diff with N other reviewers' findings. Output is parsed identically to Review.
