What it does

Branch Check is an agent skill from ossappscollective/oss-weather. Ensure you're on a correct working branch off up-to-date main before planning or editing — starting from a GitHub issue when one is in play.

Its SKILL.md is about 360 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. It works with GitHub and iOS. The repository describes itself as: An OSS weather app for iOS/Android. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/branch-check”

Workflow steps

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

  1. Check the current branch (git branch --show-current).
  2. If you are on main, you must branch — never edit directly on main.
  3. Ensure main is current first: git pull origin main (rebase onto upstream/main if working from a fork).
  4. If a GitHub issue is in play, fetch it with gh and derive the branch from it
  5. If no issue is in play, name the branch / from the change itself (e.g. feat/date-picker-range).
  6. Resolve the branch
  7. Check out the branch BEFORE planning. Interactive: confirm the branch name with the user first. --auto (caller runs autonomously): skip…

What it can do on your machine

Read from SKILL.md and the folder at commit 42715ad. 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
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.

    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

Branch Check loads about 356 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 174 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~356

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 passed

The automated check found no risky patterns in SKILL.md.

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.

Run before anything else, before planning or editing.

  1. Check the current branch (git branch --show-current).
  2. If you are on main, you must branch — never edit directly on main.
  3. Ensure main is current first: git pull origin main (rebase onto upstream/main if working from a fork).
  4. If a GitHub issue is in play, fetch it with gh and derive the branch from it:
    • gh issue view <number> --json number,title,labels — read the title and labels
    • Pick the <type> from the labels/intent (fix for a bug, feat for an enhancement, etc.)
    • Build the name as <type>/<number>-<slug>, where <slug> is the issue title lowercased, non-alphanumerics → -, trimmed (e.g. issue #1234 "ScrollView insets wrong on iOS" → fix/1234-scrollview-insets-wrong-on-ios)
  5. If no issue is in play, name the branch <type>/<short-description> from the change itself (e.g. feat/date-picker-range).
  6. Resolve the branch:
    • If it already exists, check it out.
    • Otherwise create it from up-to-date main.
  7. Check out the branch BEFORE planning. Interactive: confirm the branch name with the user first. --auto (caller runs autonomously): skip confirmation, just check out.
