+# Project Instructions (Antigravity)
+
+This project uses the **agentic-stack** portable brain. All memory, skills,
+and protocols live in `.agent/`.
+
+## Before doing anything
+1. Read `.agent/AGENTS.md` — it's the map.
+2. Read `.agent/memory/personal/PREFERENCES.md` — how the user works.
+3. Read `.agent/memory/semantic/LESSONS.md` — what we've learned.
+4. Read `.agent/protocols/permissions.md` — what you can and cannot do.
+
+## Before every non-trivial task — recall first
+For any task involving **deploy**, **ship**, **release**, **migration**,
+**schema change**, **timestamp** / **timezone** / **date**, **failing test**,
+**debug**, **investigate**, or **refactor**, run recall FIRST and present
+the surfaced lessons to yourself before acting:
+
+```bash
+python3 .agent/tools/recall.py "<one-line description of what you're about to do>"
+```
+
+If the output contains a "Consulted lessons for intent:" block with one or
+more results, show them to the user in a `Consulted lessons before acting:`
+block and adjust your plan to respect them. If a surfaced lesson would be
+violated by your intended action, stop and explain.
+
+This is how graduated lessons actually change behavior across harnesses.
+Skip it and the system is just files on disk.
+
+## While working
+- Consult `.agent/skills/_index.md` and load the full `SKILL.md` for any
+  skill whose triggers match the task.
+- Update `.agent/memory/working/WORKSPACE.md` as the task evolves.
+- Log significant actions to `.agent/memory/episodic/AGENT_LEARNINGS.jsonl`
+  via `.agent/tools/memory_reflect.py`.
+- Quick state check any time: `python3 .agent/tools/show.py`.
+- Teach the agent a new rule in one shot:
+  `python3 .agent/tools/learn.py "<the rule>" --rationale "<why>"`.
+
+## Rules that override defaults
+- Never force push to `main`, `production`, or `staging`.
+- Never delete episodic or semantic memory entries — archive them.
+- Never modify `.agent/protocols/permissions.md`.
+- Prefer using the `agentic-stack` tools for all repository-level learning and recall chores.

+# Antigravity adapter
+
+## Install
+```bash
+./install.sh antigravity
+```
+
+## What it wires up
+The Antigravity adapter drops `ANTIGRAVITY.md` into the project root. This file provides
+the system context needed for the agent to utilize the portable brain in `.agent/`.
+
+## Verify
+Ask the agent "What's in your lessons file?" — it should read
+`.agent/memory/semantic/LESSONS.md`.
+
+## Notes
+The Antigravity ruleset ensures that the agent is aware of the `agentic-stack`
+protocols and memory management tools, enabling knowledge persistence across sessions.
+It is designed to be compatible with any agent that respects root-level instruction
+files similar to `CLAUDE.md`.

+# Antigravity setup
+
+## What the adapter installs
+- `ANTIGRAVITY.md` at project root
+
+## Install
+```bash
+./install.sh antigravity
+```
+
+## How it works
+The Antigravity agent detects the `ANTIGRAVITY.md` file in the project root. This
+file instructs the agent to consult the `.agent/` folder for all knowledge, skills,
+and memory requirements. It follows a similar pattern to `CLAUDE.md` but is
+tailored for the Antigravity ruleset.
+
+## Logging note
+Antigravity agents are instructed to call `memory_reflect.py` after significant
+actions to maintain the episodic memory layer. If the harness supports automated
+hooks, these should be configured to run `.agent/memory/auto_dream.py` on session exit.
+
+## Troubleshooting
+- If the agent is not following the instructions in `ANTIGRAVITY.md`, prompt it to "Consult the project instructions in ANTIGRAVITY.md".
+- Ensure that the `.agent` folder exists and is populated. If not, re-run the installer.
+
+## Manual Usage
+The tools can be manually triggered from the terminal:
+- `python3 .agent/tools/recall.py "intent"` to search semantic memory.
+- `python3 .agent/tools/learn.py "rule"` to graduate a new lesson permanently.
+- `python3 .agent/tools/show.py` to see the dashboard of brain state.
