Who Context Packing Previewer is for

Developers and maintainers who need reviewable evidence before changing or releasing software.
Users working with AI coding, context windows, token estimates who want the documented v1.0.0 behavior.
People who prefer an open-source release with visible limitations, source, and license terms.

Intended result

Preview file selection, exclusions, token estimates, and truncation risk before an AI coding session.

This summary is reconciled from the current catalog and repository documentation.

Features in v1.0.0

Capabilities below come from the current project README and release documentation.

[](https://github.com/loganpendragonmultiverse/context-packing-previewer/actions/workflows/ci.yml)

Context Packing Previewer shows which local files would enter an AI coding context, estimates their token footprint, records exclusions, and warns when a chosen budget is close or exceeded. Nothing is uploaded.

Verified examples

Screenshots are shown only when the current README references a local source image. Otherwise, repository example files are linked directly.

Quick start

The shortest documented path into the current release.

python -m pip install .
context-preview . --include "src/**/*.py" --include "tests/**/*.py" --budget 32000
context-preview . --exclude "fixtures/**" --format json

The estimate deliberately uses a transparent four-characters-per-token approximation rather than claiming tokenizer-exact billing. Reports identify binary, non-UTF-8, oversized, and excluded files. Default exclusions cover common build directories, repositories, virtual environments, environment files, and private-key extensions.

Current limitations

These boundaries are part of the product and prevent the page from implying unverified capability.

This is a read-only preview, not a secret scanner or an AI client. Review the final file list yourself. Symlinks are skipped, and no file contents appear in the report, but filenames and absolute root paths can still be sensitive.

Requires Python 3.10 or newer. Development checks use Ruff, pytest with branch coverage, and package builds.
