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

Installation

Install the Aiwg Regenerate Codex 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/jmagly/aiwg/tree/main/agentic/code/addons/aiwg-utils/skills/aiwg-regenerate-codex
Enable the skill in any chat where you want it available.

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/jmagly/aiwg.git /tmp/aiwg
mkdir -p .claude/skills
cp -r /tmp/aiwg/agentic/code/addons/aiwg-utils/skills/aiwg-regenerate-codex .claude/skills/aiwg-regenerate-codex

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

Use it in TypingMind

Enable Aiwg Regenerate Codex 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 Aiwg Regenerate Codex 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 Aiwg Regenerate Codex 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.

Regenerate Codex Context

Regenerate the Codex context file (CODEX.md or ~/.codex/instructions.md) for OpenAI Codex integration. Performs an intelligent merge — preserving team-written content while updating AIWG context.

Core Principle

Team content is preserved. AIWG content is updated. Full injection used (Codex does not support @-link directives).

Important: No @-Link Support

Codex context files do not support @filename style includes. AIWG content is embedded directly using injection markers:

markdown
<!-- BEGIN AIWG -->
[AIWG content]
<!-- END AIWG -->

This is different from other providers that use the hook file approach.

Parameters

Flag	Description
`--no-backup`	Skip creating backup file
`--dry-run`	Preview changes without writing
`--user-level`	Update `~/.codex/instructions.md` instead of project-level `CODEX.md`
`--migrate`	Extract injection to `AIWG-codex.md` and reference from CODEX.md (future-proofing)

Context File Locations

Scope	Path	Use case
Project-level	`CODEX.md`	Project-specific AIWG context
User-level	`~/.codex/instructions.md`	User-wide context across all projects

Default: project-level CODEX.md. Use --user-level for user-wide context.

Execution Steps

Step 1: Create Backup

Unless --no-backup specified, create CODEX.md.backup-{YYYYMMDD-HHMMSS}.

Step 2: Analyze Existing Content

Read CODEX.md if it exists and categorize:

Team content (PRESERVE): Project rules, conventions, business logic, above or below AIWG block
AIWG content (UPDATE): Content between  and

Step 3: Generate AIWG Content

Generate AIWG content from installed framework manifests. Same content as other providers' hook files, but embedded inline.

Also write AIWG-codex.md as a side file for reference and for potential future migration if Codex adds @-link support.

Step 4: Inject Content

If AIWG markers found: Replace content between markers with freshly generated content.

If no markers found: Append AIWG block to end of file (before  marker if present).

markdown
[team content preserved above]

<!-- BEGIN AIWG -->
<!-- Managed by aiwg — regenerate with: aiwg-regenerate-codex -->
[AIWG content]
<!-- END AIWG -->

<!-- TEAM DIRECTIVES: Add project-specific guidance below -->

Frequently asked questions

What does the Aiwg Regenerate Codex AI skill do?

Regenerate Codex context file (CODEX.md or ~/.codex/instructions.md) with AIWG framework content

Why use Aiwg Regenerate Codex on TypingMind?

Because you install it once and use it with any model. Aiwg Regenerate Codex 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 Aiwg Regenerate Codex in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/jmagly/aiwg/tree/main/agentic/code/addons/aiwg-utils/skills/aiwg-regenerate-codex. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Aiwg Regenerate Codex?

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 Aiwg Regenerate Codex?

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

Is the Aiwg Regenerate Codex AI skill free?

Yes. It is published on GitHub by jmagly under the MIT 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.
