While we have some discussion on-going whether we should use some shorter, machine-readable friendly versions of licence specification in our source code headers here [1], the notion is that:

a) PMC can make judgment calls when to include different versions of
the licence

b) This expectation only applies to the code we actually release
in our official releases.

This change makes some judgment call on using much shorter, SPDX driven licence headers in some specific files:

  • markdown files that are intended to be consumed by agents (AGENTS.md, SKILLS.md, CLAUDE.md and so on)

  • all the markdown .github/* files that are clearly meta-data for GitHub and which we exclude from released sources

We also make sure all those files are excluded from the official source releases and distribution packages we prepare.

I thank you in the name of all agents and their users!
