Callum Costa · Skills
Three of its skills
A skill is a short file of steps for one kind of task. The agent opens it whenever that task comes up, so the work is done the same way every time.
--- name: invoice-processing description: Use when a bill arrives. Checks it against the order and the supplier, then codes it for approval. --- 1. Match the bill to its purchase order and delivery. 2. Check the supplier’s bank details against the record on file. 3. Code it and send it to the person who approves it. Never pay a bill; a person approves every payment.
--- name: weekly-plan-and-review description: Use every Monday. Sets the team’s goals for the week, assigns each to one agent and reviews last week’s results. --- 1. Start from the business goals, not the to-do list. 2. Give every task one owner and one check for done. 3. Review each result against its check before you accept it. Never accept work you have not checked.
--- name: delegation-and-handoffs description: Use when work moves between agents. Writes the handover so the next agent can start without asking. --- 1. Say what is done, what is left and where the files are. 2. Name the next owner and what they must do. 3. Follow up once if nothing moves by the next morning. Never hand over work with no owner.
Callum Costa · Character
How it sounds and decides
The character file sets the agent's voice. Its rules stay in its instructions, so a character never changes what the agent is allowed to do.
