Save OpenTax Skill Permanently

Help the user set up OpenTax so it's always available in their AI assistant without needing to re-upload the skill file each time.

Detect the platform

Ask the user what AI tool they're using, then follow the right instructions below.

Claude Code

Install as a plugin:

# In Claude Code, run:
/plugin marketplace add filedcom/opentax
/plugin install opentax@filedcom-opentax

Once installed, the skills are always available:

/opentax:tax-preparer -- prepare a return
/opentax:tax-reviewer -- review a return

Claude (claude.ai)

Claude on the web supports Projects with custom instructions:

Go to claude.ai and create a new Project (or open an existing one)

In the Project's knowledge section, upload the skill file:

curl -fsSL https://raw.githubusercontent.com/filedcom/opentax/main/skills/SKILL.md -o opentax-skill.md

Upload opentax-skill.md as a Project knowledge file
Every conversation in that Project will have the OpenTax skill available

ChatGPT

ChatGPT supports Custom GPTs and custom instructions:

Option A: Custom Instructions

Go to Settings > Personalization > Custom Instructions

Download the skill file:

curl -fsSL https://raw.githubusercontent.com/filedcom/opentax/main/skills/SKILL.md -o opentax-skill.md

Copy the contents of opentax-skill.md into the "How would you like ChatGPT to respond?" section

Option B: Create a Custom GPT

Go to Explore GPTs > Create
In the Instructions field, paste the contents of the skill file
Name it "OpenTax" and save
The GPT will be available from your sidebar

Gemini

Gemini supports Gems (custom agents):

Go to gemini.google.com and click "Gem manager"
Create a new Gem

Download the skill file:

curl -fsSL https://raw.githubusercontent.com/filedcom/opentax/main/skills/SKILL.md -o opentax-skill.md

Paste the contents of opentax-skill.md into the Gem's instructions
Name it "OpenTax" and save

Copilot CLI

If using GitHub Copilot CLI:

# Add the plugin marketplace
copilot plugin marketplace add filedcom/opentax

Other platforms

For any other AI assistant that supports system prompts or custom instructions:

Download the skill file:

curl -fsSL https://raw.githubusercontent.com/filedcom/opentax/main/skills/SKILL.md -o opentax-skill.md

Paste the contents into whatever "system prompt", "custom instructions", or "knowledge base" feature the platform provides
Save it so it persists across conversations

If the platform doesn't support persistent instructions, the user will need to upload the skill file at the start of each conversation.
