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

Installation

Install the Session Compact 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/codeaholicguy/ai-devkit/tree/main/skills/session-compact
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/codeaholicguy/ai-devkit.git /tmp/ai-devkit
mkdir -p .claude/skills
cp -r /tmp/ai-devkit/skills/session-compact .claude/skills/session-compact

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

Use it in TypingMind

Enable Session Compact 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 Session Compact 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 Session Compact 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.

Session Compact

Use AI DevKit's Jev-backed CLI to create a structured continuation artifact from a historical session. Prefer this command over a hand-written compact when it is available.

When to Use

Context is getting long and useful state needs to survive compaction.
Work is being handed to another agent or resumed after becoming stale.
A complex implementation or debugging session is closing.
Durable memory candidates or task-progress facts need to be identified after a long run.

Workflow

Find the session ID when it is not already known:

bash
npx ai-devkit@latest agent sessions --all

Produce Markdown for a human handoff:

bash
npx ai-devkit@latest agent session compact --id <session-id>

Use JSON for automation or structured inspection:

bash
npx ai-devkit@latest agent session compact --id <session-id> --format json

Add --type <provider> when the same session ID is ambiguous across providers.
Review the artifact before using its resume prompt, memory candidates, or validation claims. Compaction preserves selected transcript evidence; it does not independently verify that evidence.

Jev Availability

The command requires TYPESAFE_API_KEY. If it reports:

text
Jev is unavailable because TYPESAFE_API_KEY is not set.

report that result clearly and stop the compaction attempt. Do not silently replace it with hand-written summarization or imply that Jev classified the session. A user may explicitly request a separate manual summary afterward.

Never print, log, store, or pass the API key as a command argument. The CLI reads it from the environment.

Boundaries

The command is read-only and does not write memories or mutate tasks.
Treat memory candidates as proposals until they pass the memory skill's quality gate.
Record task progress separately when the task workflow requires it.
API, authentication, schema, or network failures with a configured key are errors, not Jev-unavailable results.

Frequently asked questions

What does the Session Compact AI skill do?

AI DevKit · Compact a historical AI coding session with Jev when context is long, work is handed off or resumed, or durable continuation facts and memory candidates need extraction.

Why use Session Compact on TypingMind?

Because you install it once and use it with any model. Session Compact 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 Session Compact in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/codeaholicguy/ai-devkit/tree/main/skills/session-compact. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Session Compact?

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 Session Compact?

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

Is the Session Compact AI skill free?

Yes. It is published on GitHub by codeaholicguy under the Apache-2.0 license. 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.
