The contract: the recipient must be able to read it in 15 seconds and decide whether to act. Every word that doesn't earn that 15 seconds is a tax.

Use this skill when the user is writing:

a first-touch outreach (founder → VC, candidate → recruiter, writer → editor, partner → partner)
a follow-up to a non-response
an intro request through a mutual connection
a warm-intro template (the "forwardable" email)
a re-engagement after a long pause

This skill does NOT:

write viral posts (use viral-text)
write long-form essays (use essay-write)
shift register of existing content (use tone-shifter)
write fiction outreach (DM to an author, fan letter) — those need a different voice.
