At a glance

Create a git branch following Sentry naming conventions. An agent skill from getsentry/skills.

  • Works in 2 steps: Resolve the work description → Classify the branch type
  • Asked to create a branch
  • SKILL.md covers Workflow and References
  • Calls git

What it does

Create Branch is an agent skill from getsentry/skills, published by the product's own GitHub organization. Create a git branch following Sentry naming conventions. Use when asked to "create a branch", "new branch", "start a branch", "make a branch", "switch to a new branch", or when starting new work on the default branch.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Git workflow. It works with Sentry. The repository describes itself as: Agent Skills used by the Sentry team for development. The licence is Apache-2.0.

When your agent uses it

  • Asked to create a branch
  • Switch to a new branch
  • Starting new work on the default branch

Example prompts

  • “create a branch”
  • “new branch”
  • “start a branch”
  • “/create-branch”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Resolve the work description
  2. Classify the branch type

What it can do on your machine

Read from SKILL.md and the folder at commit d18b7aa. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • develop.sentry.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Create Branch loads about 632 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 245 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~632

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: warnings

The automated check found patterns that need a careful read before installing.

  • WarningTells the agent its actions are pre-authorized / not to stop for confirmationSKILL.md:64
    Report the final branch name, but do not stop for confirmation.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

argument-hint
[optional description of the work]

Create Branch

Create a git branch following Sentry naming conventions. Keep this workflow non-interactive unless the user explicitly asks to choose the name manually.

Workflow

  1. Resolve the work description:

    • If $ARGUMENTS is present, use it
    • Otherwise inspect:
      bash
      git diff
git diff --cached
git status --short
    • If there are local changes, derive a short description from the diff
    • If there are no local changes, use a generic description like repo-maintenance, tooling-update, or work-in-progress

  2. Classify the branch type:

TypeUse when
featNew functionality
fixBroken behavior now works
refBehavior stays the same, structure changes
choreMaintenance of existing tooling/config
perfSame behavior, faster
styleVisual or formatting only
docsDocumentation only
testTests only
ciCI/CD config
buildBuild system
metaRepo metadata
licenseLicense changes

When unsure: use feat for new things, ref for restructuring, chore for maintenance.

  1. Generate <type>/<short-description>. Keep <short-description> kebab-case, ASCII-only, and ideally 3 to 6 words.

  2. Choose the base without prompting:

    bash
    git branch --show-current
git remote | grep -qx origin && echo origin || git remote | head -1
git symbolic-ref refs/remotes/<remote>/HEAD 2>/dev/null | sed 's|refs/remotes/<remote>/||' | tr -d '[:space:]'
    • If default branch detection fails, fall back to main, then master, then the current branch
    • If on a detached HEAD, branch from the current commit
    • If already on a non-default branch, branch from the current branch
    • Only switch to the default branch when the user explicitly asks

  3. Avoid collisions by appending -2, -3, and so on until the name is unused locally and remotely.

  4. Create the branch:

    bash
    git checkout -b <branch-name>

    Report the final branch name, but do not stop for confirmation.
