Renames project ID for telemetry from `GOOGLE_CLOUD_PROJECT` to `OTLP_GOOGLE_CLOUD_PROJECT`.
This change allows for a separate Google Cloud Project to be used for telemetry data, distinct from the project used for other services like Vertex AI or Code Assist. This enhances clarity and flexibility in project configuration.
Introduces telemetry for file create, read, and update operations.
This change adds the `gemini_cli.file.operation.count` metric, recorded by the `read-file`, `read-many-files`, and `write-file` tools.
The metric includes the following attributes:
- `operation` (string: `create`, `read`, `update`): The type of file operation.
- `lines` (optional, Int): Number of lines in the file.
- `mimetype` (optional, string): Mimetype of the file.
- `extension` (optional, string): File extension of the file.
Here is a stacked bar chart of file operations by extension (`js`, `ts`, `md`):

### Telemetry Settings
Refactors telemetry configuration to use a nested `telemetry` object in `settings.json`, for example:
```json
{
"telemetry": {
"enabled": true,
"target": "gcp"
"log-prompts": "true"
},
"sandbox": false
}
```
The above includes
- Centralized telemetry settings under a `telemetry` object in `settings.json`.
- CLI flags for the `gemini` command to override all telemetry sub-settings:
- `--telemetry` / `--no-telemetry`
- `--telemetry-target <local|gcp>`
- `--telemetry-otlp-endpoint <URL>`
- `--telemetry-log-prompts` / `--no-telemetry-log-prompts`
- Updates `packages/cli/src/config/config.ts` and `packages/core/src/config/config.ts` to read from the new settings structure and respect the new CLI flags.
- Modifies `scripts/handle-telemetry.js`, `scripts/local_telemetry.js`, and `scripts/telemetry_utils.js` to align with the new settings structure.
- Updates `docs/core/telemetry.md` to reflect the new settings structure, CLI flags, and order of precedence.
- Renames `logUserPromptsEnabled` to `logPrompts` for brevity.
### `npm run telemetry`
Add a new `npm run telemetry` command that uses `scripts/telemetry.js`, automates the entire process of setting up a local and GCP telemetry pipelines, including configuring the necessary settings in the `.gemini/settings.json` workspace file and installing required binaries (e.g. `otelcol-contrib`).

Make several changes to guide the model to request absolute paths,
reducing frequent accidental relative path tool call failures.
- Switch the parameter name: path --> absolute_path.
- Update the tool definition to strongly require an absolute path.
- Update the system prompt to indicate absolute paths are required.
- Update the system prompt tool use examples to use absolute paths.
Test case:
Open GC in GC: "Locate the primary file calling genai"
- Expected: Model opens files with absolute path, successfully.
- Actual (pre-patch): Failure, attempts to read with relative path.
- Actual (post-patch): Success, attempts to read with absolute path.
Updates the telemetry documentation and the GCP telemetry script to make it clearer that the Gemini CLI needs to be run in a separate terminal session after starting the collector script.
This addresses potential user confusion where they might expect telemetry data to appear without actively using the CLI.

Related to https://b.corp.google.com/issues/423605555 - I figured this might be a simpler solution to start with, while still also being useful on its own even if we do implement that.
Adds a script - `scripts/telemetry_gcp.js` - to simplify setting up a local OpenTelemetry collector that forwards data to Google Cloud. This is a follow up to the script for local telemetry `scripts/local_telemetry.js` added in #1015.
This script automates downloading necessary binaries, configuring the collector, and updating workspace settings.
Also includes `scripts/telemetry_utils.js` with shared helper functions for telemetry scripts. Will refactor `scripts/local_t elemetry.js` in next steps to use this shared functionality.
Updates `docs/core/telemetry.md` to include:
- A new "Quick Start" section
- Detailed instructions for the new GCP automated script
- Reorganization of existing sections for clarity

Make a pass through the docs/deployment.md file to hopefully improve readability and conciseness
Notably, I've proposed axing both the "Core Features" section - which feels too promotional this far down the folder hierarchy and which is somewhat repetitive to later in the page - and the "Basic Interaction" section - which is covered better, and makes more sense, in other parts of the documentation
This change simplifies telemetry setup for users who want to integrate with GCP, as they no longer need to configure a local collector or an explicit endpoint if their project is already set up in the environment.
This change updates the telemetry system to automatically export traces, logs, and metrics to Google Cloud Platform (GCP) if the `GOOGLE_CLOUD_PROJECT` environment variable is set and no explicit `telemetryOtlpEndpoint` is configured by the user.
Key changes:
- The default `telemetryOtlpEndpoint` in `Config` is now an empty string.
- The `initializeTelemetry` SDK logic now prioritizes:
- User-defined `telemetryOtlpEndpoint`.
- `GOOGLE_CLOUD_PROJECT` for direct GCP export.
- Console exporters as a fallback.
- If an invalid `telemetryOtlpEndpoint` is provided, it falls back to console exporters with a warning.
#750
Changes:
- Ensure proper shutdown in non-interactive mode
- Ensures the initial user prompt is logged in non-interactive mode
- Improve telemetry for streaming - handle chunks and input token count is now alongside other token counts in response
To test:
- Follow instructions in https://github.com/google-gemini/gemini-cli/blob/main/docs/core/telemetry.md#google-cloud
- Run CLI in non-interactive mode and observe logs/metrics in GCP Logs Explorer and Metrics Explorer
#750
Refactor OpenTelemetry logging for API requests, responses, and errors. Moved logging responsibility from GeminiClient to GeminiChat for more detailed logging.
#750
Add the user's decision (accept, reject, modify) to tool call telemetry to better understand user intent. The decision provides crucial context to the `success` metric, as a user can reject a call that would have succeeded or accept one that fails.
Also prettify the arguments json.
Example:

#750
Adds the following attributes to the event:
- embedding_model
- api_key_enabled
- code_assist_enabled
- debug_mode
- mcp_servers
This additional data will provide more insight into user configurations.
Adds the text content of the API response to the telemetry event. This provides more context for debugging and analysis without logging the entire, potentially large, response object.
- Adds an optional field to the type.
- Updates to include the field in the logged attributes.
- Modifies the to extract the response text using and pass it to the logger.
- Adds a new test file for the telemetry loggers, including tests for the function to verify the new functionality.
This commit refactors the telemetry system to pass a object to various logging and metrics functions. This change centralizes configuration management within the telemetry system, making it more modular and easier to maintain.
The constructor and various tool execution functions have been updated to accept the object, which is then passed down to the telemetry functions. This eliminates the need to pass individual configuration values, such as , through multiple layers of the application.
Standardizes on the distribution for local and Google Cloud setups.
Restructures the guide to present Docker and standalone binary as clear, parallel options and makes the Google Cloud command more robust.
This commit enhances the telemetry documentation with several key improvements for clarity and usability.
- Adds a prominent note clarifying that telemetry is currently incompatible with sandbox mode.
- Updates the example JSON configuration to explicitly include sandbox: false to prevent user confusion.
- Introduces a new Configurations section with instructions to create the directory.
- Adds a new step for setting necessary environment variables for the Google Cloud setup.
- Makes the command for Google Cloud more portable by using the environment variable instead of a hardcoded path.
- Re-numbers the steps in the Google Cloud setup guide to maintain a logical flow.
This commit adds a new `tutorials.md` file to the CLI documentation.
This section is intended to house various tutorials for using Gemini CLI.
The initial content includes a tutorial on setting up Model Context
Protocol (MCP) servers, using the GitHub MCP server as an example.
The `docs/cli/index.md` has been updated to include a link to this
new tutorials section.
This commit introduces the ability to use system environment variables
within the settings files (e.g., `settings.json`). Users can now
reference environment variables using the `${VAR_NAME}` syntax.
This enhancement improves security and flexibility, particularly
for configurations like MCP server settings, which often require
sensitive tokens.
Previously, to configure an MCP server, a token might be directly
embedded:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "pat_abc123"
}
// ...
}
}
```
With this change, the same configuration can securely reference an
environment variable:
```json
"mcpServers": {
"github": {
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PERSONAL_ACCESS_TOKEN}"
}
// ...
}
}
```
This allows users to avoid storing secrets directly in configuration files.
# Add .gitignore-Aware File Filtering to gemini-cli
This pull request introduces .gitignore-based file filtering to the gemini-cli, ensuring that git-ignored files are automatically excluded from file-related operations and suggestions throughout the CLI. The update enhances usability, reduces noise from build artifacts and dependencies, and provides new configuration options for fine-tuning file discovery.
Key Improvements
.gitignore File Filtering
All @ (at) commands, file completions, and core discovery tools now honor .gitignore patterns by default.
Git-ignored files (such as node_modules/, dist/, .env, and .git) are excluded from results unless explicitly overridden.
The behavior can be customized via a new fileFiltering section in settings.json, including options for:
Turning .gitignore respect on/off.
Adding custom ignore patterns.
Allowing or excluding build artifacts.
Configuration & Documentation Updates
settings.json schema extended with fileFiltering options.
Documentation updated to explain new filtering controls and usage patterns.
Testing
New and updated integration/unit tests for file filtering logic, configuration merging, and edge cases.
Test coverage ensures .gitignore filtering works as intended across different workflows.
Internal Refactoring
Core file discovery logic refactored for maintainability and extensibility.
Underlying tools (ls, glob, read-many-files) now support git-aware filtering out of the box.
