summarize-changes-headless

Current changes

!git diff HEAD

Instructions

If the diff above is empty, output exactly: No uncommitted changes.

Otherwise, output the summary in the following format with no surrounding prose:

SUMMARY
- [bullet point describing the first logical change]
- [bullet point describing the second logical change]
[continue as needed, two to five bullets maximum]


RISKS
- [risk] or NONE

Rules for the SUMMARY section:

  • Each bullet describes a logical change, not a file change. If three files were modified to implement one feature, that is one bullet.
  • Use present tense: “Add validation for email field” not “Added” or “Adding”.
  • Maximum 80 characters per bullet.

Rules for the RISKS section:

  • List only genuine risks: missing error handling, hardcoded credentials, removed tests, breaking API changes.
  • If there are no risks, write NONE on a single line.
  • Do not list stylistic observations as risks.

Output nothing else. No preamble, no “Here is the summary:”, no closing remarks. The output must be parseable by a script that splits on the SUMMARY and RISKS headers.

Note: this skill is optimized for headless use with claude -p "/summarize-changes-headless". The concise, structured output can be captured with claude -p "/summarize-changes-headless" > summary.txt and processed by downstream tools. Compare this to the interactive summarize-changes skill, which produces more readable prose suited to an interactive session. In headless mode, conciseness and consistent structure matter more than readability, because there is no follow-up turn to ask for clarification or a reformatted response.
