  • 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.

  • 5 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by antoniolg on GitHub. Read the source before you install it.

Installation

Install the Holded Invoices AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. 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.
2

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/antoniolg/agent-kit.git /tmp/agent-kit
mkdir -p .claude/skills
cp -r /tmp/agent-kit/skills/holded-invoices .claude/skills/holded-invoices
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Holded Invoices 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 Holded Invoices 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 Holded Invoices 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.

Holded invoices (PDF/Gmail → Drive archive → Holded inbox email)

Goal: send invoice/receipt PDFs to Holded's inbox email after normalizing their filenames. Prefer direct Gmail delivery via gog; the old n8n webhook is legacy fallback only.

Destinations

Configure defaults in ~/.config/skills/config.json under holded_invoices:

  • company_email
  • freelancer_email
  • sender_email
  • drive_inbox_folder_id (optional, archives a copy before sending)
  • webhook (legacy fallback)

Example:

json
{
  "holded_invoices": {
    "company_email": "empresa@holdedbox.com",
    "freelancer_email": "autonomo@holdedbox.com",
    "sender_email": "sender@example.com",
    "drive_inbox_folder_id": "drive-folder-id"
  }
}

Filename convention:

  • <company>-<YYYY>-<MM>.pdf
  • Vendor slug: lowercased, spaces → dashes, simplified (e.g. "Google INC" → google).

Scripts

1) Extract vendor + date from a PDF

  • scripts/invoice-extract.js --pdf /path/to/invoice.pdf
    • Outputs JSON: { vendor, vendorSlug, year, month }

2) Send a PDF to Holded via Gmail

  • scripts/holded-send.sh --pdf /path/to/invoice.pdf --email <holdedbox> --nombre google-2026-01.pdf
    • Uses gog gmail send with the configured sender_email or --from.
    • If drive_inbox_folder_id or --drive-folder is set, first uploads the normalized PDF to that Drive folder.
    • Use --dry-run before changing the workflow or debugging auth.

Legacy fallback: upload via n8n

  • scripts/holded-upload.sh --pdf /path/to/invoice.pdf --email <holdedbox> --nombre google-2026-01.pdf
    • Uses the webhook config or --webhook.
    • Use only when direct Gmail delivery is not available.

3) End-to-end: from a Gmail message ID

Downloads the first PDF attachment, suggests a filename, and (optionally) uploads.

  • scripts/holded-from-gmail.sh --account <gmail-account> --message-id <id> --type empresa|autonomo
    • If not configured, pass --email-empresa, --email-autonomo, --from, and/or --drive-folder.
    • Passing --webhook forces the legacy n8n path.

Flags:

  • --yes skip confirmation and upload

Agent workflow

When reviewing an email thread with a PDF invoice:

  1. Ask: is it empresa or autonomo.
  2. Download the PDF attachment.
  3. Run invoice-extract.js to infer vendor + year/month.
  4. Propose filename and ask for confirmation.
  5. Send via holded-send.sh so Drive/Gmail return observable output.

If extraction fails, ask for vendor + date and continue.

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 Holded Invoices AI skill do?

Process invoice PDFs/emails: extract vendor + date, generate normalized filename, optionally archive to Drive, and email the PDF to the right Holded inbox.

Why use Holded Invoices on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/antoniolg/agent-kit/tree/main/skills/holded-invoices. 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 Holded Invoices?

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 Holded Invoices?

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

Is the Holded Invoices AI skill free?

It is published on GitHub by antoniolg. 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.
