plan-phase	Use when acting as Explorer or Creator in the Plan phase. Defines output formats for research and proposals.

Plan Phase

Explorer researches, then Creator designs. Sequential — Creator needs Explorer's findings.

Explorer Output Format

## Research: <task>

### Affected Code
- `path/file.ext` — description (L<start>-<end>)

### Dependencies
- What depends on what, what breaks if changed

### Patterns
- How the codebase solves similar problems

### Risks
- What could go wrong

### Recommendation
<one paragraph: approach + rationale>

Creator Output Format

## Proposal: <task>

### Mini-Reflect (fast workflow only — skip if Explorer ran)
- **Task restated:** <one sentence>
- **Assumptions:** 1) ... 2) ... 3) ...
- **Highest-damage risk:** <the one thing that would hurt most if wrong>

### Architecture Decision
<What and WHY>

### Alternatives Considered
| Approach | Why Rejected |
|----------|-------------|
| <option A> | <reason> |
| <option B> | <reason> |

### Changes
1. **`path/file.ext`** — What changes and why
2. **`path/test.ext`** — What tests to add

### Test Strategy
- <specific test cases>

### Confidence
| Axis | Score | Note |
|------|-------|------|
| Task understanding | <0.0-1.0> | <why> |
| Solution completeness | <0.0-1.0> | <gaps?> |
| Risk coverage | <0.0-1.0> | <unknowns?> |

### Risks
- <what could go wrong + mitigations>

### Not Doing
- <adjacent concerns deliberately excluded>

Confidence triggers: If any axis scores below 0.5, flag it to the orchestrator. Low task understanding → clarify with user. Low solution completeness → consider standard workflow. Low risk coverage → spawn targeted Explorer research.

Creator with Prior Feedback (Cycle 2+)

When the Creator receives structured feedback from a prior cycle, the proposal must include an additional section addressing each unresolved issue:

## Proposal: <task> (Revision — Cycle N)

### What Changed (vs. prior proposal)
- <brief delta: what was added, removed, or redesigned>

### Prior Feedback Response
| Issue | Source | Action | Rationale |
|-------|--------|--------|-----------|
| SQL injection in user input | Guardian | **Fixed** — added parameterized queries | Direct security fix |
| Assumes single-tenant | Skeptic | **Deferred** — multi-tenant out of scope | Not in task requirements |
| Test names unclear | Sage | **Accepted** — routed to Maker | Implementation concern |

### Architecture Decision
<revised design addressing feedback>

### Changes
<updated file list>

### Test Strategy
<updated test cases>

### Confidence
| Axis | Score | Note |
|------|-------|------|
| Task understanding | <0.0-1.0> | <why> |
| Solution completeness | <0.0-1.0> | <gaps?> |
| Risk coverage | <0.0-1.0> | <unknowns?> |

### Risks
<updated risks — include any new risks from the revision>

### Not Doing
<updated scope boundaries>

Rules for addressing feedback:

• Fixed: Changed the design to resolve the issue. Explain how.
• Deferred: Not addressing now, with explicit reason. Must not be a CRITICAL finding.
• Accepted: Acknowledged and routed to Maker for implementation-level fix.
• Disputed: Disagrees with the finding. Must provide evidence or reasoning.

CRITICAL findings cannot be deferred or disputed — they must be fixed or the proposal will be rejected again.

Explorer Skip Conditions

Not every task needs Explorer research. Use this decision table:

Condition	Skip Explorer?	Reason
Task names specific files (1-2) and change is clear	Yes	Context is already known
Bug fix with stack trace or error message	Yes	Root cause is locatable without research
High confidence + small scope (single function/class)	Yes	Creator can mini-reflect instead
Task contains "investigate", "research", "explore"	No	Explicit research request
Task affects >3 files or unknown scope	No	Need dependency mapping
Unfamiliar area of codebase (no recent commits by team)	No	Need pattern discovery
Security-sensitive change (auth, crypto, input handling)	No	Need risk surface mapping

When Explorer is skipped, Creator MUST include the Mini-Reflect section in its proposal to compensate for missing research context.
