…#305) ## Summary `skills.NewExecutor` returned `io.EOF` to signal that the skills directory was scanned successfully but contained no `SKILL.md` files. Two callers (`NewSkillsTool` in `gemini.go`, `NewGeminiPlannerAgent` in `gemini_planner.go`) checked this with `err == io.EOF` or `errors.Is(err, io.EOF)` to decide whether to fall back to a no-op tool. `io.EOF` is surprising in this context — the caller has no stream and no end-of-input semantics, just an empty directory. A reader hitting this code has to look up what `io.EOF` means here, and any future code that wraps the error could accidentally make the comparison brittle. ## Change Define a package-level sentinel: ```go var ErrNoSkills = errors.New("no skills found") ``` Return it from `NewExecutor` when `len(found) == 0`, and update both callers to use `errors.Is(err, skills.ErrNoSkills)`. The `io` import is no longer needed in either gemini file. ## Type of Change - [ ] Bug fix - [ ] New feature - [x] Refactor - [ ] Documentation - [ ] Breaking change ## Testing - New unit tests `TestNewExecutor_NoSkills` and `TestNewExecutor_WithSkills` cover both branches. - `go build ./...` clean. - `go test ./...` passes (in particular the gemini package, since both call sites changed).

Split the single combined
aximage into two images:ax— Used by the ax-server and the Go interactions harness.ax-antigravity— Used by the antigravity harness built with python SDK.The resumption time of interactions actor reduce from ~800ms to ~500ms with the removed python dependencies. The resumption time of the antigravity python actor doesn't change much.
Tested
Deployed on substrate and run with both antigravity and antigravity-interactions.
Antigravity actor resume: ~1.6s
Interactions actor resume: ~500ms
