Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by jnsahaj on GitHub. Read the source before you install it.

Installation

Install the Prepare Branch Context AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/jnsahaj/skills/tree/main/skills/prepare-branch-context
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/jnsahaj/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/skills/prepare-branch-context .claude/skills/prepare-branch-context

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Prepare Branch Context in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Prepare Branch Context on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Prepare Branch Context is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Prepare Branch Context

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

Steps

Identify the current branch and base branch:

bash
git branch --show-current
git merge-base HEAD main

Gather the diff from main:

bash
git diff main...HEAD --stat
git diff main...HEAD

Read through the full diff carefully. Understand what files were changed, added, or removed, and what the changes do.

Review the commit history on this branch:
```
bash
git log main..HEAD --oneline
```
Read commit messages to understand the progression of changes.

Check for a related PR:

bash
gh pr list --head "$(git branch --show-current)" --json number,title,body,url,state,comments --jq '.[0]'

If a PR exists, read its title, description, and comments for additional context (acceptance criteria, discussion, review feedback).

Summarize your understanding to the user:
- What this branch does (high-level purpose)
- Key files and areas of the codebase affected
- Notable decisions or patterns visible in the changes
- Any open review comments or discussion from the PR
- Current state (clean, uncommitted changes, etc.)
Signal readiness: Tell the user you're ready for followup questions or tasks related to this branch.

Rules

Do NOT make any changes to files. This skill is read-only.
Read the actual diff content, not just the stat summary. You need to understand the code changes.
If there's no PR, that's fine — just skip that step and note it.
If the diff is very large, focus on understanding the overall structure first, then read key files in detail.
Keep the summary concise but thorough enough that you could confidently make changes to this branch.
If the branch is main or has no divergence from main, tell the user there's nothing to analyze.

Frequently asked questions

What does the Prepare Branch Context AI skill do?

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".

Why use Prepare Branch Context on TypingMind?

Because you install it once and use it with any model. Prepare Branch Context is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Prepare Branch Context in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jnsahaj/skills/tree/main/skills/prepare-branch-context. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Prepare Branch Context?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Prepare Branch Context?

As many as you like. As long as a model supports skills, you can use Prepare Branch Context with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Prepare Branch Context AI skill free?

It is published on GitHub by jnsahaj. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
