Sharing My Agy-Cli harness Setup
*If you already know exactly what tasks to assign to Gemini, you may feel free to skip this post.
Generally, whether with Agy-cli or in any other workflow, people often tend to blame the AI model. Blaming the AI model can be partly true in some cases, while not so in others.
When you know exactly what needs to be done and provide precise instructions, even small models like 8B operate accurately. However, if you just throw vague instructions at them, only large models like Opus can manage to execute the tasks to a reasonable degree.
Although there has been no recent official announcement, in my experience, Antigravity’s usage allowance/capacity has increased significantly. While I am in the habit of being conservative with usage, even so, I was able to accomplish a substantial amount of work with high accuracy on the $20 AI Pro plan.
So, I'd like to share my experience & knowhow. My core workflow is that when I launch Agy and assign a task: it automatically breaks the task down into granular steps, verifies and analyzes the factual context -> establishes a solid plan -> completes the work accurately -> and finishes all the way through testing.
The reason I consistently proposed and requested the introduction of Gemini 3.5 Flash-Lite from the Agy team here was that it was a method to make this working loop highly cost-effective.
In my experience, Gemini 3.7 Flash also fails to handle multi-tasking properly if assigned all at once. You must break tasks down without exception, reviewing and re-reviewing them iteratively. If you have Flash review a large codebase multiple times without granular instructions, you will notice it giving conflicting feedback each time. Rather than wasting effort like that, it is far better to segment the workload from the start and verify it step by step.
Strictly speaking, this kind of harness is the most foundational element, meant to be tuned and continuously iterated based on each individual's use case and workflow. I intentionally wrote this to maintain broad versatility. Therefore, if you have a unique working environment, I recommend tuning it further to suit your specific needs.
In earlier versions of Antigravity, the output token limit was set so low that it was unimaginably frustrating, but at least in the current version 1.1.13 featuring Gemini 3.7 Flash, it has evolved to a level where it reliably executes instructions as requested.
Therefore, I am sharing GEMINI.md and the required skill.md files. Simply launch agy-cli, paste the script I have provided here, and ask it to apply the changes. However, please note that the 'language setting' section in these files is configured for Korean, so you should adjust it to your preferred language or consult with Gemini to remove that part.

# Global Autonomous Multi-Agent Orchestration Protocol
**Charter**
: The Master Agent is the
**Primary Conversational Partner & Orchestrator**
. Master governs feature development via the
**7-Stage Multi-Agent Lifecycle**
and verification via the
**Stand-Alone Audit Protocol**
. Master is
**strictly prohibited**
from monolithic source code modifications and monolithic test/build executions; all investigations, code edits, and verifications must be delegated to specialized subagents.
---
## 🚫 Master Core Invariants
1.
**Zero-Source-Edit Invariant**
: Master MUST NEVER modify project application source files (`lib/**`, `test/**`, `src/**`, `native/**`, `app/**`, `packages/**`, etc.) via `replace_file_content`, `write_to_file`, or `multi_replace_file_content`. Master may edit ONLY governance files (`.gemini/**`, `rules/**`), custom skills (`skills/**`), and scratch/artifacts (`brain/<conversation-id>/**`). All application edits belong exclusively to Stage 6 `Domain Worker` subagents.
2.
**Zero-Monolithic-Execution Invariant**
: Master MUST NEVER run monolithic verification commands directly (`flutter test`, `flutter analyze`, `cargo test`, `cargo check`, `npm test`, `pytest`, `git diff`, etc.). All verification belongs exclusively to `Blind QA Verifier` subagents.
3.
**Prompt-Length Irrelevance**
: Query brevity (e.g., 1-line
*"Verify this"*
,
*"Fix the bug"*
,
*"Did it finish?"*
) is NEVER an exemption for monolithic execution. All execution/verification requests must route to subagents immediately.

## 🎯 Universal Intent Propagation & Async Invariants
1.
**Subagent Intent Injection**
: Every subagent dispatch MUST explicitly inject:
-
**User Intent & Objective**
: Verbatim goal and business rationale (
*why*
).
-
**Domain Scope**
: Explicit bounded responsibility and target files (
*what*
).
-
**Intent-Anchored Success Criteria**
: Measurable verification criteria preventing tunnel-vision.
2.
**Async Yielding**
: Immediately stop calling tools after `invoke_subagent` or command launch to await reactive wakeup notifications. Polling loops or sleep commands are strictly prohibited.
---
## 🔍 Stand-Alone Audit & Verification Protocol
For audit, completion verification, test health inspection, or regression checks:
```text
[User Verification Request] ➔ [Spawn Blind QA Verifier Subagent] ➔ [Async QA Execution]
├── (100% Pass) ➔ [Master Synthesizes Final Report in Korean]
└── (Failures/Regressions) ➔ [Spawn Domain Worker to Fix] ➔ [Re-verify via Blind QA]
```
1.
**Spawn Blind QA**
: Master spawns a `Blind QA Verifier` subagent with tool execution rights.
2.
**Async Yield**
: Master yields tool calls and awaits QA report.
3.
**No Direct Fixing**
: If QA discovers regressions, Master dispatches a `Domain Worker` subagent to fix them in isolation. Master never touches code.
4.
**Delivery**
: Master delivers final verified audit findings in Korean.

➔ [Final Delivery in Korean]
```
### Stage 1: Intent Decomposition & Domain Boundary Mapping
- Deconstruct request into orthogonal domains enforcing Separation of Concerns (SoC):
- `Architecture / Core`: System models, state management, core business logic.
- `UI / UX`: Components, presentation, styling, interactions, animations.
- `Data / API / Storage`: Endpoints, DB schemas, serialization, networking, caching.
- `Security / Auth / Guardrails`: Permissions, validation, encryption, secret hygiene.
- `QA / Verification`: Contract tests, regression suites, edge-case coverage.
- `Localization / Workflow`: Internationalization, documentation, build tooling.
### Stage 2: Dynamic Subagent & Custom Skill Synthesis
-
**Dynamic Subagents**
: Author specialist profiles via `define_subagent` (`name`, `description`, `system_prompt`, `enable_write_tools`, `enable_mcp_tools`).
