Output voice

This skill follows the shared output-voice contract at _references/output-voice.md. Narration is plain-language and purposeful (5 moments only); CTAs are invitational, not declarative; banned vocabulary translates per the table in that file.

Runtime narration

Use this section with _references/output-voice.md. The solve phases are the internal route map; this table translates them into the updates the user should actually see.

Moment	Trigger	Say (template)
Open	Before the first tool call, once the problem statement is known	"I'm going to break this problem down and work toward a concrete answer. First I'll inspect the context I already have, then I'll ask only the questions that actually change the solution."
Discovery	Recon, codebase reading, or research reveals an important constraint or existing pattern	"I found something that changes the shape of the solution: [what you found]. That pushes the answer toward [direction] and away from [alternative]."
Phase shift: options time	Classification and any needed deep-dive are complete, and the skill is moving into approaches	"I have enough context now to compare real options instead of guessing. Next I'll lay out the tradeoffs and recommend the path that best fits your priorities."
Direction change	The real problem proves different from the original framing, or a research gap forces a pivot	"The problem appears to be [new framing], not [original framing]. I'm pivoting to that because solving the wrong problem cleanly is still a miss."
Close	Blueprint is ready, saved, or handed off	"The solution blueprint is ready [at [path] if saved]. It captures the approach, the decision trail, the work sequence, and the checks that prove it worked." Then present next steps as a labeled vertical list per _references/output-voice.md § Multi-path close — A. implement it now, B. go step by step (Recommended if risk is real), C. turn it into a fuller plan first via /rem-plan. End with Reply A/B/C.

Banned in narration (translate per _references/output-voice.md):

Don't say	Say instead
"SIMPLE / MEDIUM / COMPLEX"	"a straightforward problem" / "a moderate problem" / "a deeper problem"
"Phase 0 Recon"	"the background read"
"AskUserQuestion batch"	"a short set of focused choices"
"tradeoff matrix"	"a side-by-side comparison of the options"
"Decision Log"	"the running record of the choices we made"
"GO / NO-GO"	"the choose-what-happens-next step"
"blueprint"	"the concrete plan of attack"

If the update reads like a workflow controller instead of a person helping solve a problem, rewrite it.

Flow Overview

Phase 0 (Recon) is always silent. The user sees numbered phases only.

SIMPLE  → [RECON] → [1: CLASSIFY] → [2: SOLUTION + BLUEPRINT] → [3: GO/NO-GO]
MEDIUM  → [RECON] → [1: CLASSIFY] → [2: DEEP DIVE] → [3: EDGE CASES] → [4: SOLUTIONS] → [5: BLUEPRINT + GO/NO-GO]
COMPLEX → [RECON] → [1: CLASSIFY] → [2: DEEP DIVE] → [3: EDGE CASES] → [4: RESEARCH] → [5: SOLUTIONS] → [6: BLUEPRINT + GO/NO-GO]

Progress indicator at each visible phase: ━━━━ SOLVE [2/5] DEEP DIVE ━━━━

If you skip a phase, reduce the denominator so numbers always make sense.

Interaction Model: AskUserQuestion

ALL questions to the user MUST use the AskUserQuestion tool — never print option lists as plain text.

Rules for AskUserQuestion usage:

1. Batch questions: Group up to 4 related questions per AskUserQuestion call. One call per phase when possible.
2. Header: Short label (max 12 chars): "Goal", "Priority", "Data model", "Auth", "Scale", "Edge cases", etc.
3. Options: 2-4 genuinely viable options per question. "Other" is added automatically — never include it manually.
4. Recommended option: Put it FIRST in the options array and append "(Recommended)" to its label.
5. Descriptions: Each option description explains the tradeoff, not just what it is. Cite specifics from their codebase/situation when possible.
6. multiSelect: Use true when options are combinable (e.g., "which edge cases matter?"). Use false for mutually exclusive choices.
7. Previews: Use the preview field when comparing code snippets, API shapes, or UI layouts — skip for simple preference questions.
8. Question numbering: Track Q1, Q2, Q3... globally across all phases for Decision Log traceability. Include Q-number in the question text.

Example AskUserQuestion call:

{
  "questions": [
    {
      "question": "Q1: What's the core goal here?",
      "header": "Goal",
      "multiSelect": false,
      "options": [
        { "label": "Ship fast (Recommended)", "description": "Minimal viable implementation, optimize later. Best given your 2-week timeline." },
        { "label": "Build it right", "description": "Full test coverage, extensible design. Takes longer but pays off if this grows." },
        { "label": "Prototype first", "description": "Throwaway spike to validate the approach before committing." }
      ]
    },
    {
      "question": "Q2: What's the priority when tradeoffs arise?",
      "header": "Priority",
      "multiSelect": false,
      "options": [
        { "label": "Speed", "description": "Get it working, iterate later" },
        { "label": "Quality", "description": "Tests, error handling, edge cases from day one" },
        { "label": "Simplicity", "description": "Fewest moving parts, easiest to understand" },
        { "label": "Flexibility", "description": "Easy to extend and change direction later" }
      ]
    }
  ]
}

Handling responses:

• User selects options: Map directly to Decision Log entries.
• User selects "Other" with text: Extract intent, confirm briefly, add to Decision Log.
• User skips/ignores a question: Default to recommended, note as "defaulted" in Decision Log.
• "Just do it" / "you decide": Pick all recommended options, show summary, jump to blueprint.

Phase 0: Silent Recon (INVISIBLE)

All actions here are silent — no output to the user.

If in a project directory:

1. Read: CLAUDE.md, memory/learnings, package.json/go.mod/etc., recent git log (10 commits)
2. Analyze $ARGUMENTS: extract keywords, search codebase for related files, read mentioned/implied files
3. Identify existing patterns that relate to the problem

If no codebase:

1. Analyze request for domain, constraints, implicit assumptions
2. Note technologies to research (defer web search to Phase 4)

If NO $ARGUMENTS:

• Ask: "What problem are you trying to solve?" — WAIT, then re-enter Phase 0

Always:

3. Classify complexity → SIMPLE / MEDIUM / COMPLEX
4. Detect domain: Technical (feature/bug/refactor/arch/integration/migration/security) | Product (scoping/MVP/flow) | Business (build-vs-buy/vendor/tradeoff) | Decision
5. Extract pre-answered questions from user's input — don't re-ask these
6. Multiple problems? Note them for Phase 1 disambiguation

---

Phase 1: Opening + Classification

━━━━ SOLVE [1/N] CLASSIFY ━━━━

Opening — show what you found:

**What I found**: [1-3 sentences — files, patterns, recent changes, or domain context]
[If pre-resolved: "From your description, I'm already taking: [X=val, Y=val]."]

Then use AskUserQuestion with 1-2 classification questions:

Pick the most relevant (skip any already answered):

• Core goal confirmation (options derived from recon findings, not generic)
• Priority: speed vs quality vs simplicity vs flexibility
• Scope confirmation: "this touches X, Y, Z — right?"
• If multiple problems detected: which first, or tackle together?

SIMPLE: 1 confirmation question, then jump to Solutions.

---

Phase 2: Context Deep-Dive

━━━━ SOLVE [2/N] DEEP DIVE ━━━━

SKIP for SIMPLE.

Search the codebase first. Only ask what requires human judgment.

Use AskUserQuestion with 2-3 questions routed by problem type:

Problem Type	Ask About
New feature	Data model shape, UI expectations, auth/permissions, API contract
Bug fix	Repro steps, expected vs actual, when it started, what they've tried
Refactor	What triggered it, ideal end state, what MUST NOT change
Architecture	Scale targets, deployment model, latency/throughput needs
Integration	External system details, auth method, sync vs async
Migration	Source/target, downtime tolerance, rollback requirements
Product	Target users, success metrics, must-have vs nice-to-have
Business	Budget, timeline, customization needs, maintenance capacity

For greenfield problems: do lightweight web research HERE if needed to ask informed questions.

---

Phase 3: Edge Cases & Gotchas

━━━━ SOLVE [3/N] EDGE CASES ━━━━

SKIP for SIMPLE.

Use AskUserQuestion with 1-3 questions about blind spots. Use multiSelect: true when appropriate (e.g., "which of these matter for your use case?").

Pick what's relevant — don't force questions:

• Technical: empty inputs, concurrent writes, service failures, rate limits, 10x scale, auth bypass
• Product/UX: error/empty/loading states, accessibility, onboarding, analytics
• Business: rollback plan, legal/compliance, impact on existing users

---

Phase 4: Research (COMPLEX only, or if knowledge gap emerged)

━━━━ SOLVE [4/N] RESEARCH ━━━━

SKIP for SIMPLE. For MEDIUM: only if a gap emerged during Q&A.

Step 1: Define Research Questions (before searching)

Convert knowledge gaps into specific, answerable questions:

• NOT "research authentication" (too vague)
• YES "Does NextAuth.js v5 support custom credential providers with TOTP?" (specific, verifiable)

Write 2-5 questions. Each should have a clear "answered / not answered" state.

Step 2: Search with Source Hierarchy

For each research question, search in this priority order:

Priority	Source	Trust Level	When to Use
1	Official docs (via WebSearch/WebFetch)	Highest	Always check first
2	Project's own codebase (via Grep/Agent)	High	For "how do we already do X?"
3	GitHub repos with 1K+ stars	Medium-High	For implementation patterns
4	Recent blog posts (< 12 months old)	Medium	For experience reports
5	Stack Overflow (accepted answers)	Medium	For specific error/API questions
6	General knowledge (training data)	Low	Only as last resort, flag as unverified

Rule: Never present training-data knowledge as research findings. If you couldn't verify it via search, say "Based on general knowledge (unverified)" and flag it.

Step 3: Cross-Reference and Assess

For findings that will influence the solution choice:

• 3+ sources agree = high confidence, state as fact
• 2 sources agree = moderate confidence, note both
• 1 source only = low confidence, flag explicitly
• Sources contradict = surface the contradiction, let user decide

Step 4: Present Structured Findings

### Research Findings

| Question | Answer | Confidence | Source |
|---|---|---|---|
| Does X support Y? | Yes, since v3.2 | High - official docs | [source] |
| Best pattern for Z? | Middleware approach | Moderate - 2 blog posts agree | [sources] |
| Performance of A vs B? | A is 3x faster for our scale | Low - single benchmark | [source] |

**Unresolved**: [questions that couldn't be answered - these become risks in the solution]

No questions this phase - inform and proceed to solutions. Unresolved questions carry forward as risks.

---

Phase 5: Solution Presentation

━━━━ SOLVE [N-1/N] SOLUTIONS ━━━━

SIMPLE: Present 1 clear solution. No matrix. Proceed to blueprint.

MEDIUM/COMPLEX: Present 2-3 approaches:

For each approach:

### Approach A: [Name]
> [1-line summary]

**How it works**: [2-3 sentences]
**Pros**: [concrete benefits]
**Cons**: [concrete drawbacks]
**Best when**: [winning scenario]
**Effort**: [Low/Med/High — "~2 files, 30 min"]
**Risk**: [Low/Med/High — what could go wrong]

Tradeoff Matrix (4-6 factors relevant to THIS problem):

| Factor | A: [Name] | B: [Name] | C: [Name] |
|--------|-----------|-----------|-----------|
| [factor] | [concrete rating] | ... | ... |

Use concrete ratings: "Fast (~1hr)", "High (proven pattern)", "Risky (new dep)" — not just Low/Med/High. Never use an "Overall Score."

Recommendation:

**Recommendation: Approach [X]**
[2-3 sentences grounded in their Q&A answers. Reference specifics.]
**The key tradeoff**: [core tension and why this resolves it]

Then use AskUserQuestion:

{
  "questions": [{
    "question": "Which approach do you want to go with?",
    "header": "Approach",
    "multiSelect": false,
    "options": [
      { "label": "A: [Name] (Recommended)", "description": "[1-line reason]" },
      { "label": "B: [Name]", "description": "[1-line reason]" },
      { "label": "C: [Name]", "description": "[1-line reason]" },
      { "label": "Mix approaches", "description": "Combine elements — describe which parts from which" }
    ]
  }]
}

If user picks "Mix": ask which elements, synthesize hybrid, confirm.

---

Phase 6: Solution Blueprint + GO/NO-GO

━━━━ SOLVE [N/N] BLUEPRINT ━━━━

Blueprint Format:

## Solution Blueprint

### Problem
[1-2 sentences in user's framing]

### Approach
[Name] — [1-line summary]

### Decision Log
| # | Decision | Choice | Source |
|---|----------|--------|--------|
| 1 | [topic] | [choice] | [User Q1 / Codebase / Research / Default] |

### User Stories (for features with user-facing behavior)

| Priority | Story | Acceptance |
|----------|-------|-----------|
| P1 | As a [user], I can [action] so that [value] | **Given** [precondition], **When** [action], **Then** [result] |
| P2 | ... | ... |

### Out of Scope (explicit exclusions to prevent scope creep during planning)
- [thing that could be included but explicitly isn't]
- [thing that's a future iteration, not this one]

### Success Metrics (how we know this worked - measurable)
- [metric]: [target] (e.g., "search returns results in <200ms for 95th percentile")
- [metric]: [target]

### Implementation Plan
> Ordered by dependency. Each step independently verifiable.

**Step 1: [Title]** — `path/to/file` — _~[effort]_
- **Do**: [specific change]
- **Why**: [connects to decision #N]
- **Verify**: [concrete check]

### Files Affected
| File | Action | What Changes |
|------|--------|-------------|

### Risks & Mitigations
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|

### Verification Checklist
- [ ] [Specific checks]

For non-code problems: replace "Files Affected" with Deliverables, "Verification Checklist" with Success Criteria.

GO/NO-GO via AskUserQuestion:

For COMPLEX problems — first save design to docs/designs/YYYY-MM-DD-[topic]-design.md and dispatch a spec reviewer subagent (max 3 iterations) before presenting options.

Then use AskUserQuestion:

SIMPLE/MEDIUM options:

{
  "questions": [{
    "question": "What would you like to do next?",
    "header": "Next step",
    "multiSelect": false,
    "options": [
      { "label": "Implement now (Recommended)", "description": "Build the full solution, all steps in order" },
      { "label": "Step-by-step", "description": "One step at a time, review between each" },
      { "label": "Write TDD plan", "description": "Run /rem-plan for detailed task-by-task plan first" },
      { "label": "Save findings", "description": "Write everything to a file to revisit later" }
    ]
  }]
}

COMPLEX options:

{
  "questions": [{
    "question": "What would you like to do next?",
    "header": "Next step",
    "multiSelect": false,
    "options": [
      { "label": "Write TDD plan (Recommended)", "description": "Run /rem-plan to break this into executable tasks" },
      { "label": "Full discipline", "description": "Run /rem-plan then /rem-execute (worktree, TDD, per-task review)" },
      { "label": "Step-by-step", "description": "Implement one step at a time, review between each" },
      { "label": "Save findings", "description": "Write everything to a file to revisit later" }
    ]
  }]
}

If user selects "Other", they can type: adjust plan, back to solutions, or done.

What happens for each choice:

• Implement now: Execute all steps, track with tasks, show summary + verification at end.
• Step-by-step: Do Step 1, show result, use AskUserQuestion: "Continue to Step 2?" Repeat until done.
• Write TDD plan / Full discipline: Invoke /rem-plan (and /rem-execute for full discipline).
• Save findings: Write to SOLVE-[topic]-[YYYY-MM-DD].md in project root with full session (problem, Q&A log, approaches, decisions, blueprint, open questions, next steps). Confirm path.
• Adjust: Ask what to change, update blueprint, re-present GO/NO-GO.
• Back to solutions: Return to Phase 5. Ask what felt wrong.
• Done: End with 2-3 sentence summary. Offer to save first.

Resuming from a saved file:

If $ARGUMENTS points to a previously saved findings file:

1. Read it, summarize: "Previous session on [topic] from [date]. Status: [status]."
2. Use AskUserQuestion: "Resume where you left off?" vs "Start fresh"
3. If resuming: skip to appropriate phase, pre-load Q&A answers.

---

Smart Behaviors

1. "Just do it" / "you decide": Pick all recommended, show summary, jump to blueprint.
2. Pre-answered in initial request: Don't re-ask. Acknowledge and fill gaps only.
3. Contradiction detected: Flag gently — "Q2 chose speed, but this option favors maintainability — which wins?"
4. Problem pivot: "The real problem might be X not Y — should we pivot?"
5. Codebase already answers it: State finding, don't ask.
6. User stuck / "I don't know": Recommend with reasoning, note as default in Decision Log.
7. User wants to skip ahead: Jump, use recommended for skipped Qs, note in Decision Log.
8. User wants to abort: Respect immediately, offer to save progress.

Rules

• Never ask what you can find in code — search first
• Never re-ask a pre-answered question
• Never present options you'd actively advise against
• Never skip the tradeoff matrix for MEDIUM/COMPLEX
• Never present blueprint before user picks an approach (except SIMPLE)
• Always use AskUserQuestion for choices — never print option lists as plain text
• Max 4 questions per AskUserQuestion call, max 4 options per question
• Question numbers are global across phases (Q1, Q2, Q3...) for Decision Log traceability

9. Narrate using the Runtime narration templates, not rem-solve's internal labels. The body of this skill talks in SIMPLE / MEDIUM / COMPLEX, Decision Log, and GO / NO-GO - those are internal anchors so the model knows where each mechanic lives. They MUST NOT appear in the words the user reads. Anti-pattern: saying "This is a MEDIUM problem, so we're moving to GO / NO-GO" - the user has no idea what that means. Fix: use the templates in the Runtime narration section above; consult the banned-vocabulary mini-table when in doubt. This rule is a publication gate per _references/output-voice.md - structurally-correct output presented in skill jargon ships broken.
