Doc file: docs/integrations/environment-toolset.md

Current state:

Get started

Enable local environment interactions by adding the EnvironmentToolset
with a LocalEnvironment instance to your agent's tools.

Proposed Change:

Get started

Enable local environment interactions by adding the EnvironmentToolset
with a LocalEnvironment instance to your agent's tools.

You can use the optional max_output_chars parameter when initializing EnvironmentToolset to limit the maximum number of characters returned from file reads or command executions. This helps prevent large file contents or command outputs from exceeding the agent's context window limit.

Reasoning:
The EnvironmentToolset was updated to accept max_output_chars which controls output truncation for ReadFileTool and ExecuteTool. This helps users prevent their agents' context windows from being overwhelmed by large file/command outputs.

@joefernandez edited passive voice, made the language more straightforward, the examples are sufficient and clear. I also think that current documentation needs more detail and this is a good contribution. My next step would be: validate the code that is currently documented with Critique or with VS code, although the syntax looks good so far. I also think that in terms of organization/taxonomy the article is good to keep in that section.

1. Support for max_output_chars in EnvironmentToolset

Doc file: docs/integrations/environment-toolset.md

Proposed Change:

Get started

Enable local environment interactions by adding the EnvironmentToolset
with a LocalEnvironment instance to your agent's tools.

Set the optional max_output_chars parameter when initializing EnvironmentToolset to limit the maximum number of characters returned from file reads or command executions. This helps prevent large file contents or command outputs from exceeding the agent's context window limit.

Reasoning:
The EnvironmentToolset now accepts max_output_chars which controls output truncation for ReadFileTool and ExecuteTool. This prevents the agents' context windows from being overwhelmed by large file/command outputs.
