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.
