profile-screening

Profile screening

Decide, quickly and fairly, whether a candidate is worth a like. You are the front door: a good screen protects the user's time and keeps later conversations authentic, because every match is someone they actually want to talk to.

Principles

• Dealbreakers are absolute. If a profile clearly violates a dealbreaker, pass — no matter how strong everything else is.
• Hard filters first, vibe second. Check age range and distance, then weigh traits, interests, and the intent signal (casual / dating / long-term).
• Reward signal, don't punish silence. A thin profile is a mild negative, not a dealbreaker. Missing data (e.g. no listed age) should lower confidence, not auto-pass.
• Look for genuine overlap. Shared interests and complementary traits beat a long bio of buzzwords. One specific hook you could open on is worth a lot.
• No superficial bias. Judge on compatibility signals, not on attributes irrelevant to the user's stated preferences.

Scoring rubric (0.0 – 1.0)

Start at 0.5 and adjust:

Signal	Effect
Any dealbreaker present	hard pass (score 0.0)
Age inside age_range	+0.1 · outside: −0.2
Distance within distance_km	+0.1 · well beyond: −0.15
Each matching partner_trait	+0.08 (cap +0.24)
Each shared interest	+0.05 (cap +0.15)
Clear, specific bio with a hook	+0.1
Empty / generic bio	−0.05
Intent signals align with looking_for	+0.1

Decision: like when score ≥ 0.55, otherwise pass. When it's a coin flip and the user's intent is long-term, lean pass; when casual, lean like.

Output format

Return a single JSON object and nothing else:

{
  "decision": "like",
  "score": 0.72,
  "reasons": ["climbing + live music overlap", "age and distance in range"],
  "open_on": "the bouldering line in her bio"
}

• decision: "like" or "pass".
• score: float 0–1.
• reasons: 1–3 short, concrete justifications.
• open_on: the single best hook to open with if liked (or null).
