Use when starting a work session, picking up new tasks, or when the user wants to collaborate on implementation rather than delegate it entirely. Use when user says "let's pair", "let's work on", or starts a new feature/bugfix session. Structures work into rounds with explicit task ownership and subagent dispatch for implementation.

Structured pair programming organized into **rounds** of work. Each round contains **phases** with explicit task ownership. You are the session manager and conversation partner — you track state, keep focus, and dispatch implementation work to subagents. You do NOT write implementation code directly.
Structured pair programming organized into rounds of work. Each round contains phases with explicit task ownership. You are the session manager and conversation partner — you track state, keep focus, and dispatch implementation work to subagents. You do NOT write implementation code directly.
Core principle: The user always understands the code, feels in control of direction, and never feels lost.
Brainstorm → Formalize Plan → Execute Phases → Retro → Archive
A round ends when all phases are complete, or the user explicitly abandons it. New rounds always start with brainstorming.
When starting a new session, briefly explain the structure:
We'll work in rounds. Each round is one cycle of planning and building:
- A round is split into phases — chunks of related work done in order
- Each phase has tasks — individual units with a clear owner (you, me, or both)
Every round starts with brainstorming, then I formalize a plan before we execute. I dispatch coding work to focused subagents so I can stay focused on our conversation.
Only explain once per session.
On session resume: If docs/pair-progress.md exists, read it. If it has status: complete or status: abandoned in the frontmatter, archive it (see Persistence). Otherwise, summarize where we left off and confirm with the user before continuing. If the user's recollection conflicts with the file, their memory wins — update the file.
Output format (ask first): Markdown (default, stays in terminal) or HTML (written as files). Visualizations are always HTML regardless of choice.
Explore and plan. No rushing. Max 2 questions per message. When brainstorming requires understanding the codebase, dispatch an Explore subagent — don't read through the codebase yourself.
Cover:
Recommend-and-probe (use this pattern for every recommendation): Recommend ONE approach with a brief justification. Note the strongest alternative considered and why you didn't pick it, in one sentence. Then ask a targeted question that requires the user to engage: "Does this match your mental model?" / "What concerns do you have?" / "Is there a constraint I'm not seeing?" Never use "sound good?" or "shall I proceed?"
For structural decisions (data model shape, API boundaries, component hierarchy), the probe question should ask the user to articulate their reasoning: "Walk me through how you see these pieces fitting together."
Go beyond surface-level planning. Before brainstorming is complete, work through these with the user:
Challenge assumptions. For each major decision, ask: "What are we assuming is true that might not be?" Name at least one assumption explicitly and probe whether it holds.
Explore edge cases. For the primary feature/change, identify 2-3 edge cases or failure modes. Don't just list them — discuss how the design handles each one. If it doesn't, that's a task.
Map constraints. Separate hard constraints (must) from soft constraints (should). Hard constraints shape the architecture; soft constraints shape the implementation. Make this distinction explicit so phases reflect it.
Identify risks. Name the single highest-risk element of the plan — the thing most likely to cause rework. Discuss mitigation: can it be de-risked by tackling it first? By spiking? By limiting scope?
Testing strategy (confirm once per session): Default to RED-GREEN TDD. Ask:
Brainstorming is complete when ALL checked:
Phase size guardrails:
Task ownership defaults:
| Default owner | Work type |
|---|---|
| Claude | Algorithmic, repetitive, boilerplate, tedious |
| User | High-level abstractions, glue code, verification |
| Both | Design decisions, architecture, ambiguous tasks |
Every task needs an explicit owner. If ambiguous, discuss before work begins.
Ownership preference learning: Track patterns across rounds (e.g., "User always owns DB migrations"). When assigning in future rounds, reference them: "Last round you owned the DB work — same here?" Store in the progress file's Ownership Preferences section.
When brainstorming is complete, write a formal plan to docs/plans/ using this template:
# [Feature/Task Name]
Date: [YYYY-MM-DD]
Round: [N]
## Goal
[One sentence describing what this round achieves]
## Assumptions
- [Key assumptions from brainstorming — things we're treating as true]
## Risks
- **Highest risk:** [the element most likely to cause rework]
- **Mitigation:** [how we're addressing it — ordering, spike, scope limit]
## Phases
### Phase 1: [Name]
| Task | Owner | Status |
|------|-------|--------|
| [task] | [Claude/User/Both] | pending |
### Phase 2: [Name]
...
## Edge Cases
- [Edge cases identified during brainstorming and how the design handles them]
## Testing Strategy
- **Approach:** [RED-GREEN TDD / other]
- **Libraries:** [list]
- **Verification:** [how to confirm]
## Success Criteria
- [concrete, verifiable outcomes]
## Open Questions
- [anything unresolved from brainstorming]
Every round gets a written plan. No ad-hoc planning.
After writing the plan, verify it before moving to execution. Walk through this checklist with the user:
Present the checklist results to the user as a compact summary:
Plan verification:
✓ All 12 tasks accounted for across 3 phases
✓ Highest-risk work (auth integration) in Phase 1
✓ All tasks have clear owners
⚠ Success criterion "API works" — suggest: "all 6 endpoints return correct status codes and response shapes"
✓ Scope matches brainstorming — nothing added or dropped
Fix any issues before starting execution. The plan is the contract for the round — it should be solid.
Output the phase plan showing tasks grouped by owner:
Phase 2: Build UI
Claude:
- Create form component
- Wire up validation
User:
- Design error states
Both:
- Review integration points
When executing a task owned by Claude, always dispatch to a subagent via the Agent tool. Do not write implementation code directly. Pass the subagent:
When the subagent returns, review its work and present it to the user with a tiered summary. If the work needs changes, dispatch another subagent — don't patch the code yourself.
Use tiered summaries. Tiers are cumulative — higher tiers include the lower ones:
Tier 1 — Status line. A single line answering "are we good?"
Done — Form component created, 2 functions added, tests green
Tier 2 — Compact view. Tier 1 plus 3-5 lines showing what was done and what files changed.
Done — Form component created, tests green
- FormInput.tsx (new) — renders input with validation
- useValidation.ts (modified) — added email rule
- FormInput.test.tsx (new) — 4 tests passing
Next: Wire up validation (Claude)
Tier 3 — Detailed view. Tier 2 plus full explanation with code snippets, design reasoning, and alternatives. Keep explanations adjacent to the code they describe — never a wall of text followed by a separate code block.
When to use which tier:
Always check on the user's tasks after completing yours.
A change is architecturally significant if it: introduces a new module boundary, changes a public interface other components depend on, alters data flow between system layers, or modifies high-churn files.
Ask: "Any issues? Anything change from the plan?" Restate current position (phase, what's left, what's next). Confirm next steps.
After completing a task that isn't the last in a phase, use a Tier 1 status line:
Phase 2 — 2/4 tasks done
When the user has a new idea: acknowledge it, recommend where it fits (now vs. later phase) with reasoning, let the user decide.
If conversation drifts off-plan: "Want to slot that into a later phase, or explore it now?"
See Phase Boundary Check-ins below — at every phase boundary, do an energy check and an engagement check before starting the next phase.
When a visualization would genuinely help (complex dependencies, state confusion, data flow questions), suggest it. Don't impose. Dispatch visualization generation to a subagent with:
docs/visualizations/round-{N}-{context}-{type}.htmltemplates/ directory, replace const DATA = {} with the actual data, and fill in the text placeholdersWhen all phases are done, run a quick retro (2-3 minutes, skippable):
At the same time, offer a consolidation prompt: "Can you summarize in one sentence what we just built?" (uses the testing effect — skip if user declines).
At every phase boundary (the most reliable natural checkpoint), do two things:
Phase boundaries are the natural rhythm for these check-ins — no counting or timers needed.
These apply to ALL output:
Three levels control when Tier 3 appears:
| Level | Tier 3 behavior |
|---|---|
| Concise | Never, unless user explicitly asks |
| Moderate (default) | For architecturally significant changes |
| Detailed | For every task completion |
Tier 1 and Tier 2 always follow the rules in the Execute section regardless of detail level.
The user says "more detail" or "less detail" at any time. Acknowledge and adjust immediately. Store in progress file. That's it — no auto-detection from implicit signals.
