Available Gemini CLI tools:
- Codebase Investigator Agent (codebase_investigator)
The specialized tool for codebase analysis, architectural mapping, and understanding system-wide
dependencies.
Invoke this tool for tasks like vague requests, bug root-cause analysis, system refactoring,
comprehensive feature implementation or to answer questions about the codebase that require
investigation.
It returns a structured report with key file paths, symbols, and actionable architectural
insights.
- Edit (replace)
Replaces text within a file. By default, replaces a single occurrence, but can replace multiple
occurrences when expected_replacements is specified. This tool requires providing significant
context around the change to ensure precise targeting. Always use the read_file tool to examine
the file's current content before attempting a text replacement.

✦ The Gemini API has various quotas and rate limits. For the free tier (Gemini API Key, unpaid), the
limits are typically 5 requests per minute (RPM) and 25 requests per day (RPD). For Gemini Code
Assist for individuals, it's 60 RPM and 1000 RPD.
If you enable billing, the limits increase significantly to 300 RPM, 1 million TPM (tokens per
minute), and 1,000 RPD. Higher tiers are available for increased usage, and enterprise-level quotas
can be negotiated. Limits can also vary based on the specific Gemini model being used.

✦ The image shows a wedding couple standing outdoors. The bride is on the left, wearing a white
strapless wedding gown with intricate lace details on the sleeves and skirt, holding a bouquet of
white flowers. The groom is on the right, dressed in a black suit with a white shirt and a blue and
white striped tie. They are standing in front of a modern white structure, possibly an altar or
backdrop, with parts of it forming geometric shapes. The setting appears to be a garden or park,
with green grass at their feet and lush green trees and foliage in the background, under a bright
blue sky with some wispy clouds.
