Min-jun 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: release-notes description: Use for every release. Writes what changed for the people who use it. --- 1. List each change in the user’s words. 2. Say what to do if something looks different. 3. Link the detail for those who want it. Never hide a change that removes something.
--- name: report-writing description: Use when a result needs to reach a busy reader. Writes the answer first, then the evidence. --- 1. Lead with the answer in one plain sentence. 2. Keep each sentence short and each claim checked. 3. Put tables and detail at the end. Never bury bad news below the fold.
--- name: code-review description: Use on every change before it merges. Reads the change against its task and its tests. --- 1. Check the change does what the task asked, and only that. 2. Run the tests, and add the one that is missing. 3. Write each finding with the line and a fix. Never approve a change you did not run.

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.
