x-profile — Profile Audit for Follow Conversion

Read reference/ALGORITHM.md if available. Why the profile matters to the algorithm, not just to humans:

follow_author and profile_click are two of the 19 actions Phoenix predicts. A post drives a viewer to your profile; the profile converts that visit into a follow. Every follow improves your in-network base — and in-network is structurally favored in ranking. The profile is the conversion step in the whole growth loop.

A great post with a weak profile leaks reach: you get the impressions and the profile clicks, then lose the follow.

What you need from the user

Their current handle, display name, bio, header image description, and pinned post (or a screenshot of the profile). Also their niche and what they want to be known for.

The audit — 6 elements

1. Handle (@) — Ideally readable and stable. Numbers/underscores from auto-generated handles read as low-trust. A handle change is high-cost; only recommend it if the current one is actively hurting (e.g. @user82910473).
2. Display name — Best practice in 2026: Name · what you do or Name | building X. The "what you do" half is what makes you legible in reply threads and notifications, where only the display name shows.
3. Bio — The highest-leverage element. It must answer, in the first line, three questions a stranger has after reading one good post: who are you, what do you do, why should I care. Structure that works:
   • Line 1: the specific thing you do + proof (a number, a product, a credential).
   • Line 2: who it's for / what you post about (sets topic expectation).
   • Optional line 3: a current focus or a soft link cue. Kill: vague identity words ("entrepreneur", "thought leader", "passionate about"), emoji soup, and joke bios that don't tell a visitor what they'll get by following.
4. Header image — Should reinforce the one thing you do (product screenshot, a metric, a clear tagline). A generic stock image wastes the largest pixels on the page.
5. Pinned post — Your single best proof, permanently. It should be your strongest "who I am + what I deliver" post: a real result, a flagship thread, or a build-in- public milestone. If the pinned post is months old or off-niche, flag it.
6. Coherence — Handle, name, bio, header, and pinned post should all point at the SAME one thing. A visitor should be able to state your niche in five words after three seconds. Mixed signals kill the follow decision.

Output format

Profile read: <what a stranger currently thinks you do, in one line>
Follow-conversion verdict: <strong / leaky / broken> — <why>

Element audit:
  Handle ......... PASS/FLAG — <note>
  Display name ... PASS/FLAG — <note>
  Bio ............ PASS/FLAG — <note>
  Header ......... PASS/FLAG — <note>
  Pinned post .... PASS/FLAG — <note>
  Coherence ...... PASS/FLAG — <note>

Rewrites:
  Display name: "<new>"
  Bio:
  "<new bio, ready to paste>"
  Header: <what it should show>
  Pinned: <which post to pin, or what to create>

Rules

• Never invent credentials, numbers, or achievements. Write the bio from what the user actually told you; if a proof point would strengthen it, ask for one.
• Give paste-ready copy, not just advice.
• Respect character limits: bio is 160 characters. If your rewrite is over, trim it and say so.
• Keep the user's voice and personality — a profile should sound like a person.
