Documents the new from option on create_branch, which starts a branch off an existing branch and, on GitHub, GitLab and Azure Repos, targets its pull request at that branch; the agent skill gets the same line.

Based on a merged change that lets the admin MCP and editor agent create branches from a branch other than the deploy branch. Duplicate check: open and recent docs PRs for "create_branch", "admin MCP", "sub-branch"; none found. No mint-instructions topic covers create_branch.

Note

Low Risk
Documentation-only updates to MCP and agent skill markdown; no application code or behavior changes in this PR.

Overview
Documents the admin MCP create_branch from parameter so agents and readers know they can branch off an existing feature branch (not only the deploy branch), with examples in the Admin MCP guide and matching updates in the Mintlify agent skill files (SKILL.md and skill.md).

The ai/mintlify-mcp.mdx page adds Work on a branch detail: invalid from branches are rejected, GitHub/GitLab/Azure Repos sub-branches open pull requests against the parent from branch, and auto-commit/PR behavior is clarified for sub-branches versus the deploy branch. The branches-and-publishing tool reference for create_branch is aligned with the same wording.
