The promise chain
A hook is a contract, not a trick.
Each stage must carry the same value. The subject appears early, proof follows the opening, and the action preserves the audience and promise.

What it changes
Stronger thinking before stronger copy.
PROMISE AUDIT
Repay every promise
Align title, thumbnail, opening, first proof, body, payoff, CTA, and landing page around the same value.
EXPERIMENTS
Learn from qualified action
Design controlled variants and measure downstream behavior instead of declaring a winner from retention alone.
Format native
One value unit. Rebuilt for the placement.
HookProof does not shrink the same sentence into every channel. It changes disclosure, proof, pacing, and modality while preserving the central value.

Try one prompt
Give the agent the evidence, not a hook template.
Use $write-high-retention-social-content to turn this interview into a LinkedIn post. Mine three evidence-backed angles, show the strongest proof in the next beat, and keep the CTA aligned with the audience.
