contextualize

contextualize is a utility for working with model context.

Installation

Install the core package:

uv tool install contextualize

or install with the maintained plugin bundle:

uv tool install 'contextualize[plugins]'

The plugins extra installs provider plugins from jmpaz/cx-plugins.

Commands

All of the following commands work with global flags --prompt, --wrap, --copy, --staged-copy, --count, and --write-file.

command	purpose
cat	gather file/target contents
map	survey file/folder structure(s)
shell	capture output from arbitrary shell commands
payload	compose text and file blocks from a YAML manifest
plugins	view installed plugins (see docs/plugins.md)

cat is the default command. Refs given without a subcommand run cat, so contextualize src/ README.md is shorthand for contextualize cat src/ README.md. A subcommand name wins over a same-named path; reach such a path via cat name or ./name.

Sample invocations (cat):

# gather files and copy (individually wrapped + labelled, prefixed by '--prompt') to clipboard
contextualize src/ README.md --prompt "how does this work?" --copy

# fetch a single file from a remote repo (cached under ~/.local/share/contextualize/cache/git/)
contextualize github:jmpaz/contextualize:README.md

# gather multiple files/folder(s) from a repo
contextualize https://git.sr.ht/~cismonx/bookmarkfs:README.md,doc

# fetch a single hosted UTF-8 file
contextualize https://modelcontextprotocol.io/llms.txt

Details and more examples are available in docs/usage.md.

Plugins

contextualize loads source and processor plugins from installed Python packages via the contextualize.plugins entry-point group.

See docs/plugins.md for details.
