Read the Version Header
- The file
<SOURCE>contains a header with the last version, in terms of Git hash and timestamp, of the material used to generate the current version of<TARGET>- E.g.,
% git_hash=<GIT_HASH>, timestamp=<TIMESTAMP> % <SOURCE> - E.g.,
% git_hash=f15bc6b9, timestamp=2026-07-15 14:41:12 EDT % book_springer/lectures_source/Lesson02.1_From_Data_Science_To_Decision_Science.txt
- E.g.,
Incorporate Changes
- Find what changed in
<SOURCE>from<GIT_HASH>to now, and modify<TARGET>to incorporate those changes - Follow the same style as
<TARGET>(e.g., read the corresponding.claude/skills/*.rules.md)
Verification
- Confirm every change in
<SOURCE>since<GIT_HASH>is reflected in<TARGET> - Confirm
<TARGET>still follows the style of its corresponding.claude/skills/*.rules.md
