Custom skills for AI agents
An agent skill is a package of instructions, templates, examples and, where needed, program code that an AI assistant such as Claude, ChatGPT or Copilot uses to carry out a specific task according to your company's rules. Saitai.lt builds skills and, where needed, MCP tools that connect the assistant to your systems. Prices start at €390 per tool, with a timeline of 1–2 weeks.

Who it’s for
- Every employee uses AI to prepare the same document – a quote, a contract annex or a report – in their own way, and the manager keeps fixing the format.
- Your staff upload the same price list, template or style rules into the chat every time.
- You have a procedure that AI only handles well when an experienced employee spells it out in detail.
- You want the AI assistant to look up a customer in the CRM or an order status itself, instead of waiting for someone to copy the data across.
- You need calculations or files that AI must get exactly right, such as estimates based on your formula or Excel reports based on a template.
- You want to try AI on your own processes for less than the cost of a separate AI agent.
When it’s not the right fit
- Your staff don't use an AI assistant and have no subscription. In that case, an AI agent or integration that runs in your own systems is a better fit.
- The task has to run automatically without a person, for example processing all enquiries overnight. A skill is started by a person in a chat, so this needs an AI agent.
- The task is done once a quarter – it's simpler to describe it in an ordinary set of instructions.
- There's no clear procedure, and the work is done differently every time. First you need to agree on a procedure, and then turn it into a skill.
Included
What you get
A procedure written up for the AI assistant
Using your examples and a conversation with the employee responsible, we write the instructions: the steps, rules, exceptions and the most common mistakes to avoid.
Templates and examples
We add your document templates, good and bad examples, price list or glossary to the skill. The assistant uses them every time, so your staff no longer need to upload them.
Scripts for exact actions
Calculations, file creation and data checks are handled by program code rather than the model's guesswork, so totals and formats come out exactly right.
MCP connectors to your systems
MCP (Model Context Protocol) is an open standard for connecting AI assistants to external systems. We build a connector that lets the assistant, for example, look up a customer in your CRM or check an order – only with the permissions it has been given.
Testing on your own tasks
We try the skill out on 10–20 real tasks and check that the result matches your template and rules.
Installation and a guide for your team
We install the skill in your company's AI account, or show you how to do it, and explain to your team when and how to use it.
12-month warranty
For 12 months, we fix errors in the skill and the connector free of charge. If the platform changes its skill or connector format, we assess the adaptation separately.
Price
How much does a custom AI agent skill cost?
Price from
€390
A single agent skill or tool costs from €390: that's the price of a skill that carries out one task using your template and rules, for example preparing a sales quote from your price list. Skills with calculation scripts or an MCP connector to your systems cost more – the price depends on the system and the number of actions.
Prices include all taxes – no VAT is added (we are not VAT-registered). The final price depends on the project: we put it and the timeline in the contract before work starts.
What the price depends on
- How many steps and exceptions the procedure has.
- Whether scripts are needed for calculations, files or data checks.
- Whether an MCP connector to your CRM, online store or another system is needed, and whether that system has an API.
- Whether the connector will only read data or write it as well.
- How many platforms the skill has to work on: Claude, ChatGPT, Copilot.
- How many skills are built together: shared templates and tests can lower the price of each one.
Additional costs
- The AI assistant subscription is paid directly to the platform; before signing the contract, we check whether your plan allows skills and connectors.
- We choose where to host the MCP connector based on its size: a VPS we provide (sized to your needs) or your own server; the price depends on this too. MCP connector support on our VPS costs from €29/month and covers hosting and uptime monitoring.
- New skills and changes after handover – under a separate quote, agreed in writing.
Timeline
How long does it take to build a skill?
A single agent skill takes 1–2 weeks from receiving the deposit and examples. A skill made up only of instructions and templates is usually ready in about a week, and one with scripts or an MCP connector to your system in 1–2 weeks. A set of several skills can be built and handed over in stages.
| Skill type | Example | Timeline |
|---|---|---|
| Instructions and templates | a sales quote based on your template, price list and tone-of-voice rules | 5–7 working days |
| With scripts | an estimate based on your formula, exported to Excel | 1–2 weeks |
| With an MCP connector | looking up a customer in the CRM and summarising their order history in the chat | 1–2 weeks |
Process
How it works
- Free assessment1–2 working days
We discuss the task your team carries out with an AI assistant and the platform you use. We check whether your plan allows skills and connectors.
- Specification and fixed price1–2 working days
We set out what the skill does, which templates it uses and what its limitations are. The price and timeline go into the contract, and we start once we receive the 50% deposit.
- Writing up the procedure1–3 working days
We talk to the employee who does the task best, write down the steps and exceptions, and gather 10–20 examples.
- Development and testing3–7 working days
We write the instructions, put the templates together, build scripts or an MCP connector where needed, and test everything on your examples.
- Installation and handover1 working day
We install the skill in your account, show your team how to use it and hand over a short guide.
- Warranty12 months
For 12 months, we fix errors free of charge. If you spot an inaccuracy, send it to us with an example of the chat – that way we find the cause faster.

| Connection to your systems | limited | via MCP connectors | via API, within the permissions given |

Examples
Typical scenarios
Sales quotes from a single template
- Situation
- For example, the account managers at a signage and print company prepare quotes with ChatGPT, but every quote is structured differently, and prices are sometimes taken from an out-of-date price list.
- Solution
- A skill with the quote template, the current price list and tone-of-voice rules. A script calculates prices and discounts, and the assistant writes the text and produces a Word document.
- Result
- Quotes with the same structure, prices only from the current price list and fewer corrections from the manager.
Order status right in the chat
- Situation
- For example, an online store's customer service team writes replies with Claude, but looks up order statuses in the WooCommerce admin and copies them into the chat.
- Solution
- An MCP connector that lets the assistant get the status, the tracking number and the list of items from the order number. The connector only reads data – it can't change orders.
- Result
- A draft reply with real order details and no copying, plus secure read-only access to the data.
Monthly report for the director
- Situation
- For example, a finance manager prepares a report for the director every month from an accounting software export: the same tables, the same charts, similar comments.
- Solution
- A skill with a script that calculates the figures from the export file and creates an Excel report based on a template, while the assistant writes a short commentary on the changes. The figures come only from the file.
- Result
- The same report every month, accurate figures and more time for analysis instead of arranging tables.

FAQ
Frequently asked questions
It's a folder with instructions, templates, examples and, where needed, scripts, which the AI assistant opens when it gets a suitable task – much like an employee opening a work procedure with the forms they need. Until a skill is needed, the assistant only sees its short description, so you can have many skills.
