Antigravity IDE¶
Antigravity IDE is an inventory-only backend for chat. Its persisted
conversation artifacts are encrypted, so agentgrep catalogues where they live
but cannot read them — --agent antigravity-ide never returns chat recall, at
any scope. What you can reach is its Markdown: brain notes, resolved task
plans, and skills. For searchable Antigravity history, reach for
Antigravity CLI instead.
Base path: ~/.gemini/antigravity (no observed env override).
observed_version: Antigravity 1.104.0 (observed 2026-08-08).
Antigravity IDE is documented as its own backend instead of being folded into Gemini CLI.

antigravity-ide.conversations¶
Per-conversation transcripts as loose .pb files. The observed payloads are high-entropy with no extractable UTF-8 runs, no protobuf field framing, and are not gzip/zlib — they appear encrypted or custom-encoded, so agentgrep cannot read them. The encryption is on the loose .pb file, not on protobuf: the sibling user_settings.pb is plaintext protobuf, and the protobuf blobs inside antigravity-cli.conversations SQLite rows still decode. Documented location only; unsupported for search.

Record schemas¶
Conversation artifacts (encrypted, unsupported)¶
antigravity-ide.conversations stores one conversation
artifact at conversations/<conversation_uuid>.pb. The payloads are
high-entropy bytes with no extractable UTF-8 runs, no protobuf field framing,
and no gzip/zlib magic: they are encrypted or custom-encoded, and agentgrep
cannot read them. The store is catalogued for storage inventory only and is
never searched.
The encryption is on the loose .pb file, not on protobuf. The sibling
user_settings.pb is plaintext protobuf, and the protobuf blobs inside
antigravity-cli.conversations’ SQLite rows still decode —
which is why that store stays readable while this one does not.
Implicit artifacts (encrypted, unsupported)¶
antigravity-ide.implicit files at
implicit/<conversation_uuid>.pb have the same encrypted payload shape and the
same catalogue-only treatment.
Brain and skills Markdown¶
antigravity-ide.brain and antigravity-ide.skills are
Markdown planning, memory, and instruction artifacts under brain/**/*.md and
skills/**/*.md. They are safe to inventory, but they are not prompt history or
chat transcripts and are not searched by default.
Resolved task Markdown¶
antigravity-ide.brain_resolved covers expanded task Markdown at
brain/<uuid>/task.md.resolved plus numbered .resolved.0..N snapshots. The
.resolved suffix keeps it outside the **/*.md brain glob, so it is
catalogued separately as inspectable plan text.
