Hook Design

Hook Design

Use this skill after the broad opening route is known and before prompt writing gets too concrete.

This skill is for:

• turning rough hook ideas into a stable Hook Brief
• making product reveal timing explicit
• replacing generic hook language with self-identifying specificity
• giving later skills a clean opening logic handoff

This skill is not for:

• choosing the segment family from scratch
• writing the final storyboard grid
• writing provider-ready prompts
• giving final pre-generation approval

Core Rule

The opening should create a concrete viewer question before the content feels like an ad.

Do not let the product appear before the hook logic is doing visible work.

Treat the hook as a mechanism choice, not a line-polishing exercise.

Method

Read hook-principles.md.

Use hook-examples.md for reference examples, mechanism guidance, and output format diagnosis.

Default Workflow

1. Confirm the upstream route

If the segment type or route is still unclear, use pattern-router first.

Do not let this skill replace routing.

2. Classify the hook problem

Choose the closest working need:

• rough hook idea that needs structure
• opening line that sounds generic
• product reveal that happens too early
• hook critique that needs rerun direction

Then identify the dominant Hook mechanism.

Hook Mechanism Taxonomy

Choose one primary mechanism before polishing the line.

1. boldClaim

Use when:

• the opening should challenge a stale belief
• the brand has a clear contrarian stance
• the viewer will pause to evaluate whether the claim is true

Common failure:

• vague provocation with no proof path

2. questionGap

Use when:

• the viewer has a real unanswered question
• the hook should open an information gap, not a dramatic claim
• the body can answer the question quickly

Common failure:

• generic questions with obvious answers

3. proofFirst

Use when:

• trust is the main barrier
• visible evidence or numbers can appear early
• the result is more compelling than the setup

Common failure:

• exaggerated proof with no visible credibility

4. painRecognition

Use when:

• the audience already lives with the pain
• self-identification is stronger than novelty
• the problem needs more specificity, not more hype

Common failure:

• broad category language that fits everyone and therefore no one

5. patternInterrupt

Use when:

• the first second must feel different immediately
• feed sameness is the problem
• the content benefits from a jolt before explanation

Common failure:

• shock without relevance to the next beat

6. socialOrIdentityStake

Use when:

• the pain is really about confidence, status, belonging, or presentation
• the social consequence is more legible than the technical problem

Common failure:

• melodrama that overwhelms the product logic

3. Lock the hook brief before prompt writing

Print this block first:

Hook goal:
Audience state:
Specific pain or desire:
Viewer self-identification cue:
Hook mechanism:
Opening line or opening move:
Listener reaction:
Problem deepening:
Product reveal rule:
Why this mechanism fits:
Success metric:
Hook risks:
Next handoff:

This is the required handoff object for downstream work.

4. Choose the next skill

• If the route is still unclear, go back to pattern-router
• If references exist and need decoding, hand off to reference-decode
• If the mechanism depends on frame-one conflict or visual proof, hand off to visual-hook
• If a prompt already exists, hand off to prompt-preflight-qa

Writing Rules

• make the viewer question concrete
• prefer self-recognition over category language
• choose one dominant mechanism before drafting variations
• keep listener reaction short and believable
• deepen the problem before revealing the product
• make product timing explicit instead of implied
• define success as a diagnostic signal, not a vanity metric

Failure Mode

Stop and say the hook is under-specified if you cannot determine at least:

• what the viewer should recognize about themselves
• what question the opening should create
• what mechanism is carrying the stop-scroll job
• whether the product must stay out of the opening
• which downstream skill should receive the handoff

Do not let later skills guess the opening logic from vague taste words.

Limitations

This skill only handles hook-mechanism selection and hook-brief construction.

It does not validate first-frame strength, benchmark fidelity, narrative fit across later beats, or pre-generation prompt risk.

In Practice

Most teams also need:

• upstream route selection
• reference decoding
• visual-hook translation
• preflight QA before generation

Without those steps, a strong hook brief can still degrade into generic prompts, early product reveal, or weak visual openings. Production teams avoid these gaps by chaining these stages together in an orchestrated workflow.

Orchestrated Workflows

In practice, most hook problems are workflow problems, not single-step problems.

Systems like PostPlus handle this as an orchestrated chain, where routing, hook design, reference decoding, visual execution, and QA are connected automatically.

Ecosystem Mention
