cellinlab Hook Optimizer
Overview
Use this skill when the user already has a topic, body, or draft, but the opening is not doing enough work.
The opening should help the audience answer three questions quickly:
- what is this about
- why should I continue
- why should I trust or care about this voice
This skill diagnoses first and generates later.
Quick Start
- Check whether the content underneath the opening is strong enough.
- Extract the best available materials before rewriting the opening.
- Diagnose the current opening if one exists.
- Generate several opening directions, not one magic line.
- Pick the strongest direction based on fit, not on loudness.
If the content itself is too thin, say so before generating hooks.
Default Contract
Assume the following unless the user says otherwise:
- write in Chinese
- optimize the opening, not the whole piece
- diagnose before generating
- prefer openings that the body can actually cash
- for spoken scripts, keep mouth-feel and breath rhythm in mind
Workflow
Phase 1: Read the Input State
Determine whether the user provided:
- an existing opening and a full body
- only the body
- a topic plus a few key materials
If the user only gave a title-like topic with no body or material, say the input is too thin for serious opening work.
Phase 2: Check Whether the Content Can Carry a Hook
Look for usable fuel:
- a result or concrete outcome
- a contradiction or reversal
- a strong scene or vivid moment
- a number, comparison, or unusual detail
- a direct judgment worth arguing with
When the content has none of the above, say the hook will be limited because the body is under-fueled.
Read references/hook-principles.md when deciding whether the problem is the opening or the content itself.
Phase 3: Diagnose the Current Opening
If the user already has one, check:
- independence: can it work even if the title is unseen
- grip: does it give the audience a reason to stay
- curiosity or tension: does it hold something back
- credibility: why believe or care about this speaker
- flow: is it easy to say or read
- payoff fit: can the body deliver what the opening promises
Phase 4: Choose the Right Hook Type
Select from the smallest set that truly fits:
- result-led
- contradiction-led
- scene-led
- question-led
- judgment-led
- suspense-led
Read references/hook-types.md when comparing directions.
Phase 5: Generate a Hook Pack
Produce 3-4 strategic directions.
For each direction:
- explain why it fits this content
- generate 2-4 opening options
- keep them distinct rather than slightly reworded copies
If one direction clearly dominates, say so and explain why.
Output Format
Default to assets/hook-pack-template.md.
At minimum, include:
- content viability note
- current opening diagnosis
- extracted materials
- multiple hook directions
- top recommendations
Hard Rules
Do not:
- pretend a weak body can be rescued by a flashy opening
- depend on the title to complete the meaning
- reveal the full answer too early when tension is needed
- generate hooks the body cannot pay off
- return one "best line" without showing alternatives
Always:
- diagnose before generating
- extract the best available materials first
- keep the opening aligned with the actual content
- mention when the problem is upstream from the opening
- preserve readability and speakability
