Your own skills for Halon
You can now give Halon your own skills under Halon → Skills. A skill is a short recipe for a task: when it applies, the tools it needs, and numbered steps. Halon loads it only when a question fits. See Skills.
Writing one. Choose New skill and fill in its name, when Halon uses it, its tools and its steps. Every save is a new version, and History lets you bring back an earlier one. A skill never widens anyone's access, and one that looks like it holds a password or key is refused.
Copying Firefight's. Copy on one of Firefight's skills makes Halon use your copy instead. When Firefight ships a newer version you are told, and you choose Take Firefight's version or Keep mine.
Proposed by Halon. Ask Halon in a chat to save what it just did as a skill, or work out a better way to do something a skill covers, and it proposes one. Nothing changes until someone accepts it, from the chat, from Slack or on the Skills page.
Adding and changing skills needs the Skills permission, which admins have and can grant. Agents can read and change skills over MCP and the API.
