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.
1 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 056 Design Avoid Breaking Changes 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/056-design-avoid-breaking-changes
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/056-design-avoid-breaking-changes .claude/skills/056-design-avoid-breaking-changes

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

Use it in TypingMind

Enable 056 Design Avoid Breaking Changes 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 056 Design Avoid Breaking Changes 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 056 Design Avoid Breaking Changes 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.

Avoid Breaking Changes

Review planned repository changes for breaking-change and compatibility risk before implementation or release promotion. This is an interactive SKILL.

What is covered in this Skill?

Command contract compatibility: names, inputs, owning agents, outputs, safeguards, installer registration, and command inventories
Skill routing compatibility: identifiers, metadata, descriptions, triggers, references, generated local output, and acceptance coverage
Generated-output ownership: XML/source files versus .agents/skills, public skills/, .cursor/commands, .cursor/rules, and docs/
Source and generator contracts: XML, XInclude, XSLT, Maven modules, schema expectations, and module validation
README, localized README, changelog, migration, and deprecation guidance
External and runtime contracts: APIs, schemas, data formats, configuration keys, persistence, CLI behavior, and CI expectations
Structured compatibility reports with severity-ranked findings and validation guidance

Constraints

Keep the review evidence-based, read-only, and scoped to compatibility risk unless the user explicitly asks for implementation.

MUST read references/056-design-avoid-breaking-changes.md before producing compatibility guidance
MUST identify the source artifacts reviewed and the compatibility surfaces considered
MUST distinguish confirmed breaking changes, potential risks, non-breaking changes, and unknowns that need maintainer decision
MUST include migration, deprecation, validation, or release-note guidance for intentional breaking changes
MUST respect repository source ownership: edit XML and source docs, regenerate generated output through documented workflows, and avoid direct generated-output edits unless the repository explicitly owns that file
MUST NOT modify plans, specs, source files, generated outputs, or issue descriptions during review unless the user explicitly requests implementation

When to use this skill

Review breaking changes in this spec
Check compatibility risks
Avoid breaking changes in this OpenSpec change
Review migration impact before release
Assess command and skill compatibility
Find generated output compatibility risks
Review API schema configuration or data contract changes

Workflow

Read the compatibility reference

Read references/056-design-avoid-breaking-changes.md, then identify the source artifacts to review, their authority, and whether the request is read-only review or approved implementation.

Inventory compatibility surfaces

Check commands, skills, generated outputs, XML/source ownership, README/docs, tests, CI/build gates, external contracts, runtime behavior, data/configuration contracts, and release or migration guidance relevant to the proposed change.

Classify findings

Classify each finding as BREAKING, POTENTIALLY BREAKING, NON-BREAKING, or UNKNOWN. Include the affected users, artifacts, contracts, and validation evidence or missing evidence.

Recommend migration and validation

For each confirmed or potential risk, recommend deprecation, compatibility windows, migration notes, release-note updates, generator checks, focused tests, or owner decisions.

Report the review outcome

Produce a concise compatibility report with reviewed sources, risk summary by surface, severity-ranked findings, recommended validation, and a clear no-risk statement when no breaking-change risks are found.

Frequently asked questions

What does the 056 Design Avoid Breaking Changes AI skill do?

Why use 056 Design Avoid Breaking Changes on TypingMind?

Because you install it once and use it with any model. 056 Design Avoid Breaking Changes 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 056 Design Avoid Breaking Changes in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jabrena/plinth/tree/main/skills/056-design-avoid-breaking-changes. 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 056 Design Avoid Breaking Changes?

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 056 Design Avoid Breaking Changes?

As many as you like. As long as a model supports skills, you can use 056 Design Avoid Breaking Changes with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the 056 Design Avoid Breaking Changes 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.
