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 ∄	→ ask user
Multiple lists ∃	→ present choice

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

→ present choice 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 · Remove
Issues / TODOs	Act on it · Skip · Defer
Generic	Act · Skip · Defer

2d. Execute

Decision	Behavior
Fix / Do it / Act	Perform action, show brief confirmation
Reject	Acknowledge invalid, discard, continue
Skip	Next ι silently
Defer	Append to D, continue
Modify	→ ask userfor changes → execute modified
Remove	Acknowledge, continue

3. Summary

── 1b1 Complete ──

Processed: {|Ι|} items
  Acted on:  {count}
  Rejected:  {count}
  Skipped:   {count}
  Deferred:  {count}
  Removed:   {count}

Deferred items:
  1. {title}
  2. {title}

D ≠ ∅ → present choice Process deferred now | Done.

Edge Cases

Scenario	Behavior
Ι ∄	→ ask userwhat to walk through
Multiple lists ∃	→ present choice
User stops mid-way	End early, show summary of processed
ι references files	Read relevant sections before brief
ι already resolved	Note in brief, ask user to confirm skip
|Ι| = 1	Still brief + ask — ¬skip flow

Safety Rules

1. Always investigate then brief before asking — ¬present decision without root cause analysis
2. One ι at a time — ¬batch multiple into one question
3. Track all decisions — maintain tally for summary
4. Respect user pace — ¬rush or skip ahead
