upstream-sync

microsoft/intelligent-terminal/.github/skills/upstream-sync/SKILL.md

Periodically sync new commits from microsoft/terminal into this manually-forked intelligent-terminal repo by cherry-picking commit-by-commit onto a dated sync branch, auto-skipping revert pairs and empty commits, auto-resolving known take-upstream files, and stopping cleanly on genuine conflicts. The agent (you, reading this file) is the orchestrator — the PowerShell scripts are atomic operations you invoke one at a time. Use when the user asks to "sync upstream", "pull from microsoft/terminal", "run upstream sync", "catch up to upstream", or wires this into a scheduler (weekly/daily). Designed to be safe under repeated unattended runs.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
