Aegis v1.5.4

on GitHub

Antigravity Host Targets

• Added Google Antigravity as a documented Aegis host target across three
  structural surfaces: Antigravity CLI, Antigravity IDE, and
  Antigravity App.
• Added docs/README.antigravity.md with install guidance, shape-specific
  notes, verification expectations, and official reference links.
• Added skills/using-aegis/references/antigravity-tools.md so Aegis skills can
  map file, shell, search, skill, subagent, and web-tool references onto
  Antigravity host equivalents.

Gemini CLI Transition Boundary

• Kept Gemini CLI as a transitional compatibility surface instead of retiring
  it in this release.
• Documented Google's 2026-05-19 transition announcement, the 2026-06-18
  consumer service-stop boundary, and the enterprise / paid API key caveats.
• Preserved GEMINI.md, gemini-extension.json, and the Gemini tool mapping
  while Antigravity CLI / IDE / App support matures.

Host Compatibility Guardrails

• Updated the host compatibility matrix, known limitations, release checklist,
  prompt hygiene boundary, README files, and skill references for Antigravity
  support.
• Added tests/e2e/antigravity-host-boundary-check.sh and wired it into the
  Layer 1 fast check.
• The new guardrail records Antigravity as structural support only, captures
  Antigravity CLI 1.0.1 plugin discovery evidence, and prevents wording that
  marks Gemini CLI as retired or retiring.
