## Edge Quality Review

**REQUIRES edges (strong dependency):** Used when the target skill is a genuine prerequisite. `self-consistency → cot` is correct: you cannot run multi-sample consistency voting without first understanding chain-of-thought output format. `goal-decomposition → planning-decomposition` is correct: decomposing goals at the conceptual level precedes procedural decomposition.

**LEARN_BEFORE edges (sequencing):** Used when the target should be studied first for comprehension, not for execution. `self-consistency → prompt-engineering` is sequencing: prompt engineering scaffolds the prompts that self-consistency samples from.

**RECOMMENDED_WITH edges (synergy):** Used when both skills amplify each other but neither is a hard prerequisite. `meta-prompting → llm-orchestration` is synergy: meta-prompting generates sub-prompts dynamically; orchestration manages their routing.

**Potential concern — mutual reference between `reasoning-under-uncertainty` and `hypothesis-generation`:**  
`hypothesis-generation → reasoning-under-uncertainty` (RECOMMENDED_WITH) and `reasoning-under-uncertainty → hypothesis-generation` (RECOMMENDED_WITH) form a bidirectional recommended pair. This is intentional and not a cycle in the REQUIRES/LEARN_BEFORE sense. The graph schema allows undirected synergy pairs.

## Risk Assessment

| Risk | Severity | Outcome |
|---|---|---|
| Duplicate cot/tot addition | HIGH | ✅ Avoided — confirmed by anti-duplicate check |
| Schema version bump | LOW | ✅ Not bumped — no schema change |
| Orphan node (no edges) | LOW | ✅ None — all 9 nodes have ≥2 edges |
| Edge pointing to non-existent node | HIGH | ✅ None — all targets verified |
