Gemini 4 Argon is engineered for deep reasoning, making it exceptionally capable when designing multi-component architectures or isolating subtle, hard-to-reproduce bugs. However, using heavy reasoning effort for routine mechanical edits or simple refactoring runs up token counts and introduces unnecessary latency. Paired with the latest updates in Antigravity CLI v1.3.5 and v1.3.6, these seven tips demonstrate how to calibrate reasoning depth, isolate side questions, offload repetitive work to subagents, and keep long development sessions lean and responsive.

1. Right-Size Reasoning Effort (/effort)

Gemini 4 Argon defaults to intensive reasoning. While invaluable for complex problem-solving, this level of deliberation is overkill for routine syntax updates or formatting passes. Matching effort to task requirements is the first step toward efficient token management.

• Default (medium): Recommended as the standard setting for typical coding and implementation tasks.
• Planning & Debugging (high): Step up reasoning effort when drafting architectural plans, analyzing complex dependency trees, or debugging elusive runtime issues.
• Quick Refactors (low): Dial down effort when renaming variables, scaffolding boilerplate, or applying straightforward structural edits where low latency matters most.

2. One-Shot Model Consults (/model <name> <prompt>)

There is no need to keep your entire interactive session locked to the heaviest model. You can keep your fast, lightweight default model active and bring in Argon on demand for isolated high-complexity decisions.

• Direct a single prompt to Argon when diagnosing an intricate bug or reviewing a core design proposal.
• Once that specific turn completes, the CLI automatically falls back to your faster default model, preventing unintended resource consumption across routine interactions.

3. Delegate to Subagents and Follow Up with @<subagent>

Context-heavy operations—such as comprehensive codebase searches or generating exhaustive test suites—can rapidly inflate your main session's token history. Offloading these tasks to dedicated subagents keeps the primary Argon thread focused.

• Role Specialization: Delegate repo exploration, implementation, or test writing to specialized subagents like coder, tester, or reviewer.
• Direct Messaging: Prefix commands with @<subagent> to route instructions directly to an individual agent without disrupting the parent context.
• Interactive Interrupts: New in v1.3.6, press Ctrl+K whenever a subagent surfaces a question to review and respond immediately from the terminal.

4. Ask Side Questions Without Polluting Context (/btw)

Checking an API syntax rule or testing an isolated command option in the middle of a task should not bloat your active conversation history.

• Invoking /btw opens a lightweight side overlay directly within the terminal interface.
• You can query the model for reference answers and close the overlay without adding a single token to your main trajectory or persistent context.

5. Inspect Changes Directly in Terminal (/diff)

Reviewing diffs thoroughly should not require exiting the terminal or launching a separate graphical diff tool.

Antigravity CLI v1.3.5 through v1.3.6 brings substantial enhancements to the built-in /diff view:

• File Tree Navigation: An integrated file tree layout that outlines all modified project files.
• Change Statistics: Clear per-file change statistics right in the view.
• Commit Message Copy: Direct copying of commit messages right from /diff.
• Highlighted Commit Tree: A visually distinct commit history tree directly within the terminal display.

6. Context Compaction with One-Step Chaining (/compact [next prompt])

When a long session approaches context limits, previous workflows required compacting history first and then entering the subsequent prompt in a separate step. Antigravity CLI consolidates these into a single command.

• Summarize accumulated conversation history and trigger your next instruction in one fluid step.
• Context weight drops immediately, and the new task begins execution without manual context-clearing delays.

7. Auto Mode (Shift+Tab or --mode auto)

Repeated manual confirmation for non-destructive commands can disrupt developer flow during rapid prototyping.

• Activation: Launch the CLI with --mode auto or toggle the mode interactively by pressing Shift+Tab.
• Streamlined Execution: Speeds up command reviews by minimizing interactive interruptions during routine runs.
• Built-in Guardrails: Automatically blocks commands that attempt to upload sensitive data.
