# 1b1 — One by One
Let:
ι := single item from the list
Ι := full list of items to process
D := [] — deferred items accumulator
Walk through Ι from conversation one at a time. ∀ ι: brief context → ask decision → execute.
## Instructions
### 1. Identify Ι
Scan conversation for most recent list (review findings, plan tasks, GitHub issues, TODOs, any enumerated list).
Argument ∃ (e.g. `/1b1 review findings`) → narrow to matching list.
| Condition | Action |
|-----------|--------|
| Ι ∄ | → DP(B) |
| Multiple lists ∃ | → DP(A) |
### 2. ∀ ι ∈ Ι (sequential)
#### 2a. Investigate
ι references file → read relevant lines + surrounding context. ι references issue → `gh issue view`. Trace root cause — ¬stop at symptom.
**Root cause first:** before presenting options, understand *why* ι exists. Read code, check history, follow references. Analysis must be grounded in evidence, ¬speculation.
#### 2b. Brief
```
── Item {N}/{|Ι|}: {title} ──
Summary: {what the item is and its root cause — 2-3 lines}
Benefit: {what improves if we act on it}
Tradeoff: {cost, risk, or complexity of acting}
Recommendation: {Fix now | Defer | Skip | Reject} — {1-line rationale}
```
#### 2c. Ask Decision
→ DP(A) Options adapted to ι type. Always include **Skip**.
| Item type | Options |
|-----------|---------|
| Code findings | **Fix now** · **Reject** (invalid) · **Skip** · **Defer** (valid, not urgent) |
| Tasks / plan items | **Do it** · **Skip** · **Modify** · **Remov
