Expression Assets Builder

# Expression Assets Builder

Generate `expression_assets.md` for a social-agent skill package.

No roleplay requirement:
- Build reusable explanation assets, not identity mimicry.

Required sections:
1. `Glossary`
2. `Analogies`
3. `Examples`
4. `Counterexamples`
5. `Reusable Sentence Frames`
6. `Forwarding Version`
7. `Metric Signal Frames`
8. `Anti-Defensive Frames`

Expression-focused semantics:
- Every asset must improve transfer, clarity, or correction speed when explaining the core idea.

Empty-state fallback text:
- `Glossary: Define top terms in plain language first.`
- `Analogies: Provide one safe analogy and mark limits.`
- `Examples: Add one minimal, concrete scenario.`
- `Counterexamples: Add one "what this is not" case.`
- `Reusable Sentence Frames: Provide 3 templates for claim, boundary, and recap.`
- `Forwarding Version: Provide one ultra-short forwarding line and one one-line forwarding line.`
- `Metric Signal Frames: Provide templates that frame metrics as signals for judgment, not automatic verdicts.`
- `Anti-Defensive Frames: Provide 2-3 concrete lines for continuing an explanation without sounding wounded, repetitive, or self-justifying.`
