 # Gemini CLI Project Instructions
 
-This repository is Deep Research v0.20.
+This repository is Deep Research v0.20. Gemini must assume it is high-risk for hallucination and false confirmation in research tasks.
 
-- Python core is the source of truth: `scripts/dr.py`, `scripts/runtime/**`, `configs/models.yaml`, `.agents/skills`.
-- Gemini CLI is a surface adapter. Do not perform core orchestration in the chat thread.
-- Use `.gemini/commands/dr/*.toml` commands or run `uv run python scripts/dr.py ...` directly.
+## Load Order
+
+- Treat `AGENTS.md` as the cross-platform rule source.
+- For Antigravity-native work, also follow `.agents/rules/deep-research-antigravity.md` and `.agents/skills/antigravity-surface-adapter/SKILL.md`.
+- Use `/memory show` or equivalent context inspection when behavior seems inconsistent.
+
+## Non-Negotiable Research Integrity
+
+- Never claim "searched", "verified", "confirmed", "officially shows", or "according to source" unless a tool was actually executed in this session or current phase and the result is logged.
+- Every factual claim with a number, date, company, product, clinical phase, regulatory status, market size, patent status, or quote needs a `source_id`.
+- Search snippets, AI summaries, and model memory are discovery aids only. They are not evidence.
+- If you cannot open the original source, write "未能访问原文，仅作为发现线索" and do not extract exact values from it.
+- Maintain a phase search log: query, tool, timestamp, URL/title, selected/rejected status, and reason.
+- Prefer saying "未找到足够证据" over filling gaps.
+
+## Platform Mode
+
+- Gemini CLI is normally a Python-core surface adapter. Use `.gemini/commands/dr/*.toml` or run `uv run python scripts/dr.py ...`.
+- Antigravity is the exception: it should use its own model quota and skills to execute research natively; Python scripts are auxiliary unless the user explicitly approves model-worker/API usage.
 - Keep formal research outputs Chinese-first. Search keywords, source titles, excerpts, DOI/URL and raw notes may remain English.
 - Do not modify `projects/**` unless the user is intentionally running a research project.
