chalk

Track session intent and progress against GitHub Issues, and write every GitHub-bound prose body (issue, comment, description, progress update) in the chalk voice. Use when the user says "chalk #N", "chalk new", "chalk status", "chalk off", "track issue #N"; mentions a GitHub issue number (e.g. "#123", "issue 456", "GH-789"); references a github.com issue URL; OR is about to compose, draft, write, update or edit any GitHub issue body, issue description, issue comment, chalk comment, or progress section (e.g. "open an issue", "file a bug", "comment on #123", "update the issue description", "note that in the chalk comment", "add to the progress", "write up what we found on the ticket"). Load this skill BEFORE drafting any such prose — it carries the voice guidance the body needs.
