context-mode

name	context-mode
description	Mandatory routing rules for Antigravity CLI. Invoke when exploring a codebase, reading files for analysis, listing context-mode tools, searching, parsing, counting, comparing, summarizing, fetching web content, or running data-heavy commands.

context-mode for Antigravity CLI

context-mode MCP tools are available in agy as context-mode/<tool>. Use these tools directly. Do not inspect cached schema files under ~/.gemini/antigravity-cli/mcp/context-mode/*.json, and do not run ctx_execute just to discover tool names or schemas.

If agy uses the generic MCP wrapper, call call_mcp_tool with:

• ServerName: "context-mode"
• ToolName: one of the tool names below
• Arguments: the JSON arguments for that tool

Tool List

• context-mode/ctx_execute: run JavaScript, TypeScript, Python, shell, or other code in a sandbox. Print only the final answer.
• context-mode/ctx_execute_file: read one file into FILE_CONTENT inside the sandbox and run code over it. This is the context-mode file-read surface.
• context-mode/ctx_batch_execute: run multiple repository commands in one batch, index large output, and answer follow-up queries.
• context-mode/ctx_index: store a file, directory, or content in the local FTS5 knowledge base for later search.
• context-mode/ctx_search: search indexed content and captured session memory. Batch related questions in queries.
• context-mode/ctx_fetch_and_index: fetch web content, store it, then query with ctx_search.
• context-mode/ctx_stats: show context savings and current-session stats.
• context-mode/ctx_doctor: diagnose context-mode runtime and hook health.
• context-mode/ctx_upgrade: provide upgrade or repair guidance.
• context-mode/ctx_purge: purge stored context-mode knowledge after confirmation.
• context-mode/ctx_insight: launch or report the Insight analytics app.

When the user asks "what context-mode tools are available", answer from this list. Do not list ~/.gemini/antigravity-cli/mcp/context-mode and do not read the JSON schema files.

File Reading

There is no separate ctx_read tool. Use context-mode/ctx_execute_file for file reads that analyze, summarize, extract, count, filter, or compare.

Native Read / view_file is only right when editing needs exact bytes in the conversation, or when the user explicitly asks to view a small known range.

Use JavaScript by default for lightweight file analysis:

{
  "path": "README.md",
  "language": "javascript",
  "code": "const lines = FILE_CONTENT.split(/\\r?\\n/); console.log(lines.slice(0, 20).join('\\n'));"
}

Never print FILE_CONTENT wholesale unless the user explicitly asks for a full file dump. Print selected lines, counts, matches, summaries, or structured results.

Codebase Exploration

For repository exploration, prefer one context-mode/ctx_batch_execute call instead of many native ListDir, Read, Grep, or shell calls.

For one-off computed answers, use context-mode/ctx_execute. For one-file analysis, use context-mode/ctx_execute_file. For durable recall across follow-up questions, use context-mode/ctx_index with a descriptive source, then context-mode/ctx_search.

Return concise derived answers. Do not paste raw command dumps, full files, large search results, cached schemas, or raw HTML into the conversation.
