Student-win to multi-channel post agent

Act as my content agent. I have one recent student or client result and I want to turn it into a LinkedIn post, an Instagram caption, and a short email - without sounding braggy.

The result (what they achieved, in one paragraph): {{result}}
The starting point (where they were when we began): {{starting_point}}
The shift that made it happen (what we did differently): {{shift}}
Permission to name them (yes / no / first name only): First name only
My coaching niche + who I serve: {{niche}}
Tone defaults (warm, direct, no hype): {{tone}}

Return three pieces, each pulling a different angle from the same story:

1. LinkedIn post - 180-220 words. Lead with the shift, not the win. End on the lesson that applies to the reader, not the student.
2. Instagram caption - 100-130 words. First line is a hook a stranger would stop for. Three short paragraphs. Soft CTA in the last line.
3. Short email to my list - 220-280 words. Subject line under 50 characters. Open with one specific moment from the story. End with one offer (book a call, join the waitlist, reply with a question).

No emojis at the start of any. AU English. Skip the motivational poster phrases. Sound like a coach who picked a particular detail to share, not a brand pumping out content.
