ctxkit 1.2.5

Create AI prompts with files, directories, and URLs

ctxkit

ctxkit is a command-line tool for constructing AI prompts containing files, directories, and URL content. For example:

ctxkit -m "Please review the following source code file." -f main.py

In the preceding example, the -m argument outputs the message text, and the -f argument outputs the main.py file text as follows.

Please review the following source code file.

<main.py>
print('Hello, world!')
</main.py>

API Calling

ctxkit supports calling the Ollama API and the Grok (xAI) API via the --ollama and --grok arguments, respectively.

Ollama

ctxkit -m 'Hello!' --ollama gpt-oss:20b

Grok

export XAI_API_KEY=<key>
ctxkit -m 'Hello!' --grok grok-3

You can call an API with a prompt from stdin by passing no prompt items:

echo 'Hello!' | ctxkit --ollama gpt-oss:20b

Copying Output

To copy the output of ctxkit and paste it into your favorite AI chat application, pipe ctxkit's output into the clipboard tool for your platform.

macOS

ctxkit -m 'Hello!' | pbcopy

Windows

ctxkit -m 'Hello!' | clip

Linux

ctxkit -m 'Hello!' | xsel -ib

Usage

Using the ctxkit command line application, you can add any number of ordered context items of the following types: configuration files (-c), messages (-m), file path or URL content (-i and -f), and directories (-d).

usage: ctxkit [-h] [-g] [-c PATH] [-m TEXT] [-i PATH] [-f PATH] [-d PATH]
              [-x EXT] [-l N] [-v VAR EXPR] [--ollama MODEL | --grok MODEL]
              [--temp TEMP] [--topp TOPP]

options:
  -h, --help          show this help message and exit
  -g, --config-help   display the JSON configuration file format
  -c, --config PATH   process the JSON configuration file path or URL
  -m, --message TEXT  add a prompt message
  -i, --include PATH  add the file path or URL text
  -f, --file PATH     add the file path or URL as a text file
  -d, --dir PATH      add a directory's text files
  -x, --ext EXT       add a directory text file extension
  -l, --depth N       the maximum directory depth, default is 0 (infinite)
  -v, --var VAR EXPR  define a variable (reference with "{{var}}")
  --ollama MODEL      pass to the Ollama API
  --grok MODEL        pass to the Grok API
  --temp TEMP         set the response temperature
  --topp TOPP         set the response top_p

Variables

You can specify one or more variable references in a message's text, a file path, a directory path, or a URL using the syntax, {{var}}. A variable's value is specified using the -v argument. For example:

ctxkit -v package ctxkit -m 'Write a 100 word or less description of the Python "{{package}}"'

Configuration Files

ctxkit JSON configuration files allow you to construct complex prompts in one or more JSON files.

Example: Write Unit Tests

To generate a prompt to write unit tests for a function or method in a module, create a configuration file similar to the following:

{
    "items": [
        {"message": "Write the unit test methods to cover the code in the {{scope}}."},
        {"file": "src/my_package/{{base}}.py"},
        {"file": "src/tests/test_{{base}}.py"}
    ]
}

In this example, the "scope" variable allows you to specify what you want to write unit tests for. The "base" variable specifies the base sub-module name. To generate the prompt, run ctxkit:

ctxkit -v base main -v scope "main function" -c unittest.json

Configuration File Format

The ctxkit -g argument outputs the JSON configuration file format defined using the Schema Markdown Language.

# The ctxkit configuration file format
struct CtxKitConfig

    # The list of prompt items
    CtxKitItem[len > 0] items


# A prompt item
union CtxKitItem

    # Config file path or URL
    string config

    # A prompt message
    string message

    # A long prompt message
    string[len > 0] long

    # File path or URL text
    string include

    # File path or URL as a text file
    string file

    # Add a directory's text files
    CtxKitDir dir

    # Set a variable (reference with "{{var}}")
    CtxKitVariable var


# A directory item
struct CtxKitDir

    # The directory file path or URL
    string path

    # The file extensions to include (e.g. ".py")
    string[] exts

    # The directory traversal depth (default is 0, infinite)
    optional int(>= 0) depth


# A variable definition item
struct CtxKitVariable

    # The variable's name
    string name

    # The variable's value
    string value

Development

This package is developed using python-build. It was started using python-template as follows:

template-specialize python-template/template/ ctxkit/ -k package ctxkit -k name 'Craig A. Hobbs' -k email '[e-mail]' -k github 'craigahobbs' -k noapi 1
