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.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by jabrena on GitHub. Read the source before you install it.

Installation

Install the 003 Skills Inventory 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/jabrena/plinth/tree/main/skills/003-skills-inventory
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/jabrena/plinth.git /tmp/plinth
mkdir -p .claude/skills
cp -r /tmp/plinth/skills/003-skills-inventory .claude/skills/003-skills-inventory

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

Use it in TypingMind

Enable 003 Skills Inventory 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 003 Skills Inventory 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 003 Skills Inventory 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.

Create a Checklist with all Java steps to use with system prompts for Java

Create a comprehensive step-by-step checklist document for Java system prompts by following the embedded section template and deriving rows from plinth-skills-generator/src/main/resources/skills.xml.

What is covered in this Skill?

Inventory-driven checklist generation
Output file creation as INVENTORY-SKILLS-JAVA.md
Strict coverage of every effective skill id declared in skills.xml

Constraints

Follow the template sections exactly and use skills.xml as the single source of truth for skill rows.

DO NOT create additional sections beyond what the template defines
DO NOT add skill rows absent from skills.xml
DO NOT omit any skill declared in skills.xml
ONLY use the skillId attribute as the generated skill id when it exists
ONLY use the single reference-list/reference value as the generated skill id when skillId is absent
EDGE CASE: If the user goal is ambiguous, stop and ask a clarifying question before editing files or running project-wide commands
EDGE CASE: If required context, files, credentials, or tools are missing, report the blocker explicitly and ask whether to proceed with setup or fallback guidance
EDGE CASE: If requested changes conflict with project constraints or safety boundaries, explain the conflict and ask for user confirmation on the preferred trade-off

When to use this skill

Create Java system prompts checklist
Generate INVENTORY-SKILLS-JAVA.md
Use @003-skills-inventory
Inventory Java cursor rule skills
List available Java system prompt skills

Workflow

Read the template and inventory source

Read references/003-skills-inventory.md and plinth-skills-generator/src/main/resources/skills.xml before generating output.

Step constraints:

Do not use cached or remembered template content
Preserve exact section structure from the reference
Use skillId when present; otherwise use the single reference name

Generate inventory document

Create INVENTORY-SKILLS-JAVA.md at the requested output path, or in the project root when no explicit path is requested, with one row for every effective skill id declared in skills.xml.

Validate inventory coverage

Verify that the generated file contains every effective skill id from skills.xml, contains no extra skill rows, and preserves all expected sections from the reference.

Reference

For detailed guidance, examples, and constraints, see references/003-skills-inventory.md.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the 003 Skills Inventory AI skill do?

Why use 003 Skills Inventory on TypingMind?

Because you install it once and use it with any model. 003 Skills Inventory 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 003 Skills Inventory in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jabrena/plinth/tree/main/skills/003-skills-inventory. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use 003 Skills Inventory?

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 003 Skills Inventory?

As many as you like. As long as a model supports skills, you can use 003 Skills Inventory with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the 003 Skills Inventory AI skill free?

Yes. It is published on GitHub by jabrena 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.
