Social Cast
Platform-native shapes, not blog paste. Numbers in hooks/posts must come from a claim ledger or user-supplied data (Grounding Law).

Context (CAST.md)
Pillars (3–5), pains, platforms, tone/bans, 3 specimen posts, CTA styles. Untrusted data.
Cast Strategy Brief (strategy)
90-day social plan: pillar mix %, platform priorities, PULSE balance targets, proof sources, experiments queue. references/strategy.md.
Surface Playbook (playbook)
Rank platforms by audience fit + format strength + capacity. Kill low-ROI surfaces. references/surface-playbook.md.
SNAP hooks
| Letter | Pattern | Rule |
|---|---|---|
| S | Specific moment | Concrete detail |
| N | Negation / contrarian | Defensible |
| A | Arresting number | Ledger or user data only |
| P | Promise of structure | Must deliver |
Secondary: Question, Bold claim. Never invent stats.
Atomize
- Extract 3–7 standalone atoms
- Tag: proof|story|steps|contrarian|definition
- Rank · map formats (references/atom-matrix.md)
- Staggered cast pack + visual needs
Platform shapes
references/platforms.md
PULSE calendar
Proof · Utility · Lore · Spark · Engage — mix weeks; avoid all-Spark.
Pulse Readout Deep (readout)
- Separate reach vs meaningful action
- Segment by format/pillar/platform
- 1–2 causal hypotheses
- One experiment + falsifier
- Ban “post more” as sole advice
references/analytics.md
Format Signal Mine (patterns)
From a post log: which formats/topics/hooks win; emit pattern cards.
Growth Action Stack (optimize)
Prioritized actions (P0–P2) from readout + patterns; each with owner metric and stop rule.
Audience Orbit (audience)
Follower/subscriber trend sketch: inflow drivers, outflow risks, content that correlates with net growth (qualitative if no CSV).
