ctx-index

Index a local file or directory into context-mode's persistent FTS5 knowledge base so future ctx_search calls can retrieve focused snippets without rereading raw files. Trigger: /context-mode:ctx-index

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 mksglu on GitHub. Read the source before you install it.

Installation

Install the Ctx Index 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.
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/mksglu/context-mode.git /tmp/context-mode
mkdir -p .claude/skills
cp -r /tmp/context-mode/skills/ctx-index .claude/skills/ctx-index

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

Use it in TypingMind

Enable Ctx Index 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 Ctx Index 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 Ctx Index 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.

Context Mode Index

Index local project content for later search.

Instructions

Prefer the ctx_index MCP tool when it is available.
Ask for a path only if the user did not provide one and the current project root is ambiguous.
Use path, not large inline content, so file bytes do not enter the conversation.
For repository indexing, pass conservative bounds and a clear source label:

javascript
ctx_index({
  path: ".",
  source: "project:<name>",
  maxDepth: 5,
  maxFiles: 200
})

If MCP tools are unavailable, fall back to the CLI:

bash
context-mode index . --source project:<name>

Report the indexed source label, file count or section count, and the matching search command:

javascript
ctx_search({ source: "project:<name>", queries: ["..."] })

Safety

Do not index dependency directories, build outputs, secrets, or generated artifacts.
Prefer --exclude or exclude for project-specific noisy paths.
For broad repos, ask the user before raising maxFiles above 500.

Frequently asked questions

What does the Ctx Index AI skill do?

Why use Ctx Index on TypingMind?

Because you install it once and use it with any model. Ctx Index 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 Ctx Index in TypingMind?

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

Which AI models can use Ctx Index?

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 Ctx Index?

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

Is the Ctx Index AI skill free?

It is published on GitHub by mksglu. 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.
