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

Installation

Install the Fix 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/TheBushidoCollective/han.git /tmp/han
mkdir -p .claude/skills
cp -r /tmp/han/plugins/core/skills/fix .claude/skills/fix

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

Use it in TypingMind

Enable Fix 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 Fix 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 Fix 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.

fix

Name

han-core:fix - Debug and fix bugs, errors, or unexpected behavior

Synopsis


/fix [arguments]

Description

Debug and fix bugs, errors, or unexpected behavior

Implementation

Investigate, diagnose, and fix bugs or unexpected behavior in the codebase.

Process

Follow this process to fix bugs:

Reproduce the issue: Confirm the bug exists and understand when it happens
Gather information: Error messages, logs, stack traces, user reports
Form hypothesis: What might be causing the issue?
Investigate: Use debugging tools, add logging, trace execution
Identify root cause: Find the actual source of the problem
Implement fix: Change code to resolve the issue
Verify fix: Confirm the bug is resolved and no new issues introduced
Add regression test: Prevent the bug from returning

Bug Fixing Principles

Understand before fixing:

Don't guess and patch - find the root cause
Reproduce reliably before attempting fix
Understand why the bug exists, not just symptoms

Fix properly:

Fix the cause, not symptoms
Consider edge cases and similar issues
Add tests to prevent regression
Document why the fix works

Verify thoroughly:

Original issue resolved
No new bugs introduced
Related scenarios still work
Tests pass (existing + new)

Examples

When the user says:

"This function throws an error when passed null"
"The page crashes on mobile devices"
"Users report checkout fails intermittently"
"Fix the memory leak in the background worker"
"Debug why tests are failing on CI"

Debugging Techniques

Add logging:

typescript
console.log('Value at checkpoint:', value)
logger.debug('Processing item', { id: item.id, status: item.status })

Use debugger:

typescript
debugger;  // Browser will pause here

Binary search:

Comment out half the code
If bug disappears, it's in that half
Repeat until isolated

Compare working vs broken:

What changed between working and broken?
Git bisect to find breaking commit
Compare with known-good version

Output Format

After fixing:

markdown
## Bug Fix: [Brief description]

### Issue
[What was broken and how it manifested]

### Root Cause
[Why the bug existed]

### Fix
[What was changed and why it fixes the issue]

### Verification
[Evidence the fix works - use proof-of-work skill]
- Original issue no longer reproduces
- Tests pass (include test output)
- Related scenarios still work

### Prevention
[What test was added to prevent regression]

Notes

Use TaskCreate to track debugging steps
Document findings even if you don't find the root cause immediately
Use proof-of-work skill to show the bug is actually fixed
Consider using boy-scout-rule skill to improve surrounding code
Add test to prevent regression (use test-driven-development skill)

Frequently asked questions

What does the Fix AI skill do?

Debug and fix bugs, errors, or unexpected behavior

Why use Fix on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/TheBushidoCollective/han/tree/main/plugins/core/skills/fix. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Fix?

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 Fix?

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

Is the Fix AI skill free?

It is published on GitHub by TheBushidoCollective. 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.
