Context

PR #154 (imsg agent skill) originally documented poll behavior that lives in PR #155, not on main:

• poll send echoing --question as a visible plain caption
• the --comment override
• inbound backfill of a native poll's question from its caption row

Shipped imsg 0.12.2 has none of these (imsg poll --help exposes only --question/--option, no --comment), so #154 was decoupled: those lines were stripped so the skill only documents shipped behavior and can merge independently.

What to do after #155 merges

Once #155 (fix(poll): make the poll question visible both directions) lands on main, re-add to .agents/skills/imsg/SKILL.md:

1. On imsg poll send, note --question is echoed as a plain caption right after the poll (what recipients see), and --comment overrides the echoed text.
2. On read, note imsg history/watch backfill an inbound native poll's question from its caption.

The exact wording removed in the decouple commit is the starting point. Verify each claim against merged main behavior (live imsg poll send + imsg history) before re-adding.
