name	fpf-strategize
description	Bet on a method family — choose WHICH CLASS of approach to explore, not which specific solution. First-class creative act. MUST invoke for T4 architectural work before variant generation.

What this skill IS

This is strategic betting, not variant selection. You are choosing which class of approach to bet on — scoping the search space for variant generation. "We'll explore variants within [family X] because [reason]."

Strategizing ≠ SoTA survey. SoTA maps the landscape; strategizing bets on a region. Strategizing ≠ variant selection. Strategy scopes the family; selection picks from generated variants.

Prerequisites

• PROB-* or ANOM-* exists with acceptance spec
• SOTA-* exists (if missing: invoke /fpf-sota first)

Constraints (quality bar)

• C1: ≥2 candidate method families evaluated
• C2: Each family assessed for admissibility against PROB-* constraints
• C3: Primary bet stated with rationale (why this family over others)
• C4: Variant generation axes defined (what will differ between variants within this family)
• C5: Invalidation conditions stated (what would cause a pivot to different family)
• C6: Links to PROB-* and SOTA-*
• C7: Scaling-Law Lens (SLL): for each family, state how it scales with more resources (compute/data/time). Minimum two measurement points (Scale-Probe) to claim a slope. Elasticity class: growing | plateau | declining. At comparable budgets, prefer the family with better scaling slopes (BLP — Bitter Lesson Preference).

Format

# Strategy Card
- **ID:** STRAT-...  **Problem:** PROB-...  **SoTA:** SOTA-...
- **valid_until:** YYYY-MM-DD

## Candidate families
| # | Family | Admissible? | Scaling (SLL) | Key risks |
| F1 | ... | Y/N | growing/plateau/declining | ... |
| F2 | ... | Y/N | growing/plateau/declining | ... |

## Bet
Primary: [family]. Rationale: ...

## Variant generation axes
(diversity dimensions within chosen family)

## Invalidation conditions
(what would cause a pivot)

## valid_until
(when does this strategy bet go stale? Tech landscape changes, new SoTA emerges)
