finishing-a-development-branch is agent-read markdown (skill) from ganyuanran/aegis: Use when verified work needs integration or cleanup of an existing task-created branch/worktree, or the user explicitly requests merge, PR, or branch lifecycle handling..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

# Finishing a Development Branch
## Overview
Integration choice and checkout lifetime are separate. Verify first, mutate only
task-owned resources, then prove what was removed or retained.
**Core principle:** fresh evidence -> authorized integration -> ownership-aware
cleanup -> Git/path readback.
**Announce at start:** explain which branch/worktree lifecycle is being closed.
## Step 1: Environment and Ownership Detection
Read the task's `TaskStartSnapshot` and current repository state. Record:
- root, `HEAD`, branch/detached state, upstream divergence, and active Git ops;
- staged/unstaged/untracked paths and the task-owned delta;
- `git worktree list --porcelain`;
- branch/worktree creator, task ownership, base branch, and cleanup trigger.
Stop on conflicts, detached state, failed verification, dirty/untracked state in
a cleanup target, or unknown ownership. Do not infer the base from the names
`main` or `master`; use task records, repository authority, or explicit user
direction. Never auto-stash, reset, clean, pull, rebase, amend, force-push, or
bypass hooks.
If no task-created branch/worktree exists and integration was not requested,
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
