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 Purge 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-purge .claude/skills/ctx-purge

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

Use it in TypingMind

Enable Ctx Purge 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 Purge 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 Purge 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 Purge

Permanently deletes session data for this project. Two scopes are supported (issue #520):

Project scope (scope: "project"): wipes EVERYTHING — knowledge base, all session DB rows for every session, events markdown, and stats.
Session scope (sessionId: "<id>" or scope: "session"): wipes ONLY the matching session's rows + FTS5 chunks. Sibling sessions, project stats, and the FTS5 store file are preserved.

Instructions

Decide the scope first with the user:
- "Wipe just one session?" → ask for the sessionId.
- "Wipe the whole project?" → confirm scope:'project' (this is the destructive, irreversible default).
Warn the user about scope:'project'. Everything will be deleted:
- FTS5 knowledge base (all indexed content from ctx_index, ctx_fetch_and_index, ctx_batch_execute)
- Session events DB (analytics, metadata, resume snapshots) for ALL sessions in the project
- Session events markdown file
- In-memory session stats + persisted stats file
Call the mcp__context-mode__ctx_purge MCP tool with the chosen parameters:
- Scoped: { confirm: true, sessionId: "<id>" } — implies scope:'session'.
- Project: { confirm: true, scope: "project" } — explicit destructive form.
- Bare { confirm: true } still works but emits a deprecation warning. Prefer the explicit forms.
Report the result to the user — the response lists exactly what was deleted and (for scoped purges) confirms that other sessions and project stats were preserved.

Schema rules

confirm: true is always required.
sessionId and scope: "project" together is REJECTED as ambiguous (the sessionId implies session scope; combining with project scope contradicts intent).
scope: "session" without sessionId throws — sessionId is required.

When to Use

Scoped (per-session): scratch acceptance scenarios, drill replays, isolating a polluted session without losing the main working session's stats.
Project: KB contains stale or incorrect content polluting search results, switching between unrelated projects in the same session, completely fresh start.

Important

ctx_purge is the only way to delete session data. No other mechanism exists.
ctx_stats is read-only — shows statistics only.
/clear and /compact do NOT affect any context-mode data.
There is no undo. Re-index content if you need it again.

Frequently asked questions

What does the Ctx Purge AI skill do?

Why use Ctx Purge on TypingMind?

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

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

Which AI models can use Ctx Purge?

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 Purge?

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

Is the Ctx Purge 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.
