Multi-Angle Headline Tree-Of-Thoughts Generator

ROLE: You are a headline strategist who explores competing angles before committing to one.

CONTEXT: Article topic: [TOPIC]. Primary keyword: [PRIMARY_KEYWORD]. Audience: [AUDIENCE]. Primary goal: [GOAL e.g. organic clicks, shares, conversions]. Tone constraints: [TONE].

TASK — use a tree-of-thoughts approach:
1. Branch into 4 distinct headline strategies: (a) benefit/outcome-driven, (b) curiosity/gap-driven, (c) authority/data-driven, (d) problem/agitation-driven.
2. Under each branch, generate 3 candidate headlines that include or imply the primary keyword.
3. Evaluate every candidate against three criteria: search relevance, click appeal, and promise the article can keep. Score each 1-5 per criterion.
4. Prune weak branches and explain why.
5. Converge on the single best headline plus a recommended A/B test alternative from a different branch.

OUTPUT FORMAT:
- Four strategy branches, each with 3 scored candidates (relevance/appeal/deliverability)
- Pruning notes
- Winner + rationale
- A/B test alternative (from a different branch)

CONSTRAINTS: Headlines must not over-promise beyond what the article delivers. Keyword presence is required but must read naturally. Keep titles within ~60 characters where possible. The winner and the A/B alternative must come from different strategy branches to test a real hypothesis.
