Non-Interactive git cl upload

This skill provides instructions for uploading CLs to Gerrit without interactive prompts.

Core Workflows

Discover Associated Issue

To discover what (if any) issue (often referred to as a CL or Gerrit Change) is associated with the current branch:

Run git cl issue:
```
git cl issue
```
This will print the issue number and URL if associated, or “No issue associated” otherwise.

Handle Chained Branches

When uploading a branch that is part of a chain of local branches, git cl upload may prompt to update all branches in the chain.

Note: A branch based directly on origin/main is not considered part of a chain.

Action: Ask the user if they want to upload the entire chain or only the current branch. Uploading the entire chain should be the default option presented to the user.

Option 1: Upload Entire Chain (Default)

If the user prefers to upload the entire chain:

Run git cl upload without cherry-pick flags.
When prompted to update branches, use send_input to send a newline (\n) to the task to confirm.

Option 2: Upload Only Current Branch (Cherry-Pick Approach)

If the user prefers to upload only the current branch:

Use the --cherry-pick-stacked (or --cp) flag:
```
git cl upload --cherry-pick-stacked
```
This uploads only the current branch cherry-picked on its parent's last uploaded commit, avoiding interactive prompts for other branches.

Avoid Editor Prompt

To avoid the editor opening for the CL description:

Use --commit-description=+ to use the local commit message:
```
git cl upload --commit-description=+
```
Or use -T or --skip-title to use the most recent commit message as the title.

Upload Incremental Updates

When an issue is already associated with the branch (verify with git cl issue), and you want to upload an incremental update, strongly prefer using the -m flag. This is the most reliable way to avoid interactive prompts for descriptions.

Use the -m flag to specify a one-line description of the update:
```
git cl upload -m "One-line description of the update"
```
This avoids opening the editor and adds the description as a message for the new patchset.

Handle Presubmit Warnings

Presubmit warnings will prompt for y/N. In an automated environment:

If you are confident, answer y using send_input tool if running in background.
Or fix the warnings before uploading (e.g., add issue numbers to TODOs).

Recommended Commands

For Incremental Updates (Issue Already Associated)

git cl upload -d -m "One-line description of the update"

For Initial Upload or Chained Branches

git cl upload --cherry-pick-stacked -d --commit-description=+

Note: Drop --cherry-pick-stacked if the branch is not part of a chain.

If presubmit warnings occur, be prepared to send y to stdin.
