SonyWWS / ATF
Authoring Tools Framework (ATF) is a set of C#/.NET components for making tools on Windows. ATF has been in continuous development in Sony Computer Entertainment's (SCE) Worldwide Studios central tools group since early 2005. ATF has been used by most SCE first party studios to make many custom tools such as Naughty Dog’s level editor and shader editor for The Last of Us, Guerrilla Games’ sequence editor for Killzone games (including the Killzone: Shadow Fall PS4 launch title), an animation blending tool at Santa Monica Studio, a level editor at Bend Studio, a visual state machine editor for Quantic Dream, sound editing tools, and many others.

The timeline comes from the creation date and the releases on the Repository Host, the Admission, the Star History, and the Observations. Star milestones show only when the Star History records the day. The list shows up to 5 stable releases from the latest 10 releases recorded. When none of them is stable, one item counts the pre-releases. On the chart of net stars each day, a solid line marks each recorded release.

Health facts
Measured facts in four separate dimensions, each with a date and a source. AwesomeRepos does not add them into one score. AwesomeRepos reads the weekly commits, the changelog, and the community files each week for the 5,000 visible repositories with the most stars and for each rising repository. How AwesomeRepos defines each check
Copies a prompt for a coding agent. It has 1 task for the maintainers of SonyWWS/ATF.
Improve the Health Facts of the GitHub repository SonyWWS/ATF. AwesomeRepos measures facts about how a repository is maintained, released, secured, and documented. Its page for this repository is https://awesomerepos.com/SonyWWS/ATF. A change to the repository can improve each of the item below. Each item gives the measured fact or score, and a task. 1. A release in the last 365 days Fact: No GitHub release (read on 2026-11-12). Rule: The newest published GitHub release (a pre-release counts; a draft does not) is 365 days old or less. A repository that publishes only tags, or only to a package registry, has no GitHub release. The release refresh reads the 10 newest releases after each push to the repository, and at least each 30 days. The index refresh reads the date of the last push each day. Task: Prepare a release, but do not publish it. Find the changes since the newest release, propose the next semantic version and the release notes, and ask me to publish the GitHub release. If nothing changed since the newest release, skip this item. If the project publishes only to a package registry, add a CI step that also makes a GitHub release for each version tag. Rules for this work: - Each file must be true for this project. Do not copy text that does not apply to it. - Do not choose a licence, a contact, or a release version for me. Ask me. - Do not publish a release, change a repository setting, or push to the default branch. Make the changes on a new branch. - Keep each change small, and run the checks of this repository before you finish. - At the end, list each item as DONE, SKIPPED (with the reason), or NEEDS A DECISION (with the question). AwesomeRepos reads these facts again in its next scan. The definitions of the checks: https://awesomerepos.com/health-facts
