What it does

Prepare Branch Context is an agent skill from jnsahaj/skills. Analyze the current branch's diff from main and related PR to build context for followup requests. Triggers on "prepare context", "branch context", "catch me up", "what's on this branch".

Its SKILL.md is about 550 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. The repository describes itself as: Agent skills I use daily.

When your agent uses it

  • Prepare context
  • Whats on this branch

Example prompts

  • “prepare context”
  • “branch context”
  • “catch me up”
  • “/prepare-branch-context”

Workflow steps

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

  1. Identify the current branch and base branch
  2. Gather the diff from main
  3. Review the commit history on this branch
  4. Check for a related PR
  5. Summarize your understanding to the user
  6. Signal readiness: Tell the user you're ready for followup questions or tasks related to this branch.

What it can do on your machine

Read from SKILL.md and the folder at commit 170b0b9. 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

Prepare Branch Context loads about 552 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~53
When it runs · the whole SKILL.md, loaded when a task matches
~552

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 251 words (~552 tokens).

“Build a comprehensive understanding of the current branch so you can handle followup requests with full context.”
