Skill: New Branch Bootstrap

Description

Canonical recipe for spinning up a fresh working branch off the latest upstream main. Use this skill whenever the user says things like "make a new branch off fetched origin/main", "peel off a fresh branch", "dust off #NNNN", or otherwise signals the start of a new unit of work.

This replaces the ad-hoc prose that used to be retyped at the start of every session.

When to Use

• Starting any new feature, fix, chore, or refactor.
• Rebasing a stale PR onto current main (see Rebase variant).
• Reproducing a CI failure from a clean baseline.

Preconditions (verify before branching)

1. Clean worktree. If git status --porcelain is non-empty, ask the user before proceeding.
2. Upstream remote present. git remote -v must list upstream pointing at meshtastic/Meshtastic-Android. If only origin exists on a fork, treat origin as upstream.
3. Secrets: nothing to bootstrap — secrets.defaults.properties is tracked and is the secrets plugin's fallback, so every flavor builds without a local secrets file.

Standard Recipe

# 1. Fetch latest upstream
git fetch upstream --prune --tags

# 2. Create the branch from upstream/main (never from a local stale main)
git switch -c <branch-name> upstream/main

# 3. Sanity check
git --no-pager log -1 --oneline

Branch Naming

Use conventional-commit style prefixes that match the PR title convention in .github/copilot-pull-request-instructions.md:

Prefix	Use for
feat/<scope>	New user-visible behavior
fix/<scope>	Bug fixes
refactor/<scope>	Code structure changes, no behavior change
chore/<scope>	Tooling, deps, CI, cleanup
docs/<scope>	Documentation only

Keep the slug short and kebab-case, e.g. fix/r8-animation-release, chore/koin-application-migration.

Rebase Variant

When the user says "rebase #NNNN" or "dust off PR NNNN":

git fetch upstream --prune
gh pr checkout <NNNN>          # checks out the PR head locally
git rebase upstream/main
# Resolve conflicts, then:
git push --force-with-lease

Never use plain --force. Always --force-with-lease to avoid clobbering collaborator pushes.

Post-Branch Checklist

• Branch name follows conventional prefix.
• ANDROID_HOME exported (see AGENTS.md workspace bootstrap).
• Optional: run ./gradlew assembleDebug once to catch environment regressions before editing.

Tip: Delegate Long Audits to a Subagent

If the user's opening prompt is a sweeping audit or investigation (e.g. "audit changes since v2.7.13 for regressions", "investigate why animations are broken on release"), dispatch the Explore subagent (read-only, broad fan-out) so file dumps stay out of the main context and you get back just the conclusion; use the gradle-runner subagent for heavy ./gradlew runs. See CLAUDE.md → "Delegate to keep context lean".
