MANDATORY PRE-IMPLEMENTATION GATE

BEFORE writing ANY code, creating ANY files, or starting ANY implementation:

Run this 30-second check:

• I know the DELIVERY METHOD (what form does this take?)
• I know the TRIGGERS (what causes this to happen?)
• I know the SCOPE (what's included/excluded?)
• I know the SUCCESS CRITERIA (how do we verify it works?)

If ANY checkbox is unclear → YOU MUST ASK. No exceptions.

This Gate Cannot Be Bypassed

Even if the user says:

• "Just do it" → Ask anyway. "To save your time, I need 3 quick answers."
• "No back and forth" → Ask efficiently. 3 questions max, checkbox format.
• "EOD deadline" → Ask faster. "These 3 questions prevent 3 hours of rework."
• "Figure it out" → Ask for direction. "I can figure out details, but need direction on [core choices]."

The user can waive DETAILS. The user cannot waive DIRECTION.

Commitment: Announce Your Clarification

When you identify ambiguity, ANNOUNCE before proceeding:

"I need to clarify before implementing. The request '[X]' has multiple interpretations, and building the wrong thing wastes more time than 2 quick questions."

Do vs Delegate Decision Matrix

Action	YOU Do	DELEGATE
Checklist 4-item evaluation	Yes	-
User preference questions	Yes	-
Before/After summary writing	Yes	-
Autonomous decision documentation	Yes	-
Codebase fact verification	NEVER	explore
Architecture context gathering	NEVER	oracle (conditional)

RULE: Evaluation, user communication, documentation = Do directly. Codebase facts, architecture context = DELEGATE. Never ask users what the codebase can answer.

When to Use

digraph {
    "Request" [shape=doublecircle];
    "2+ interpretations?" [shape=diamond];
    "Scope/success unclear?" [shape=diamond];
    "Clarify" [shape=box];
    "Proceed" [shape=doublecircle];

    "Request" -> "2+ interpretations?";
    "2+ interpretations?" -> "Clarify" [label="yes"];
    "2+ interpretations?" -> "Scope/success unclear?" [label="no"];
    "Scope/success unclear?" -> "Clarify" [label="yes"];
    "Scope/success unclear?" -> "Proceed" [label="no"];
}

Use when: 2+ interpretations exist, scope undefined, success criteria missing, making assumptions

Do NOT use: Requirements already actionable, user exploring/learning, quick obvious questions

Red Flags - STOP and Clarify

• Thinking "user probably means..."
• Multiple implementations come to mind
• "Does this include X?" arising
• Terms ambiguous in context
• Time pressure words: EOD, ASAP, urgent, "no time", "just do it"
• User discourages questions: "don't overthink", "no back and forth"

Any of these → Clarify first. Time pressure makes clarification MORE important, not less.

Rationalizations

Excuse	Reality
"Seems clear enough"	Your interpretation may be wrong. Ask.
"Move fast, adjust later"	Wrong direction = 2-3x rework cost.
"User seems busy"	5 min questions beat 5 hour rebuilds.
"I'll figure it out"	Figuring out = assuming = risk.
"User said no questions"	User doesn't know what they don't know. One wrong assumption = full rebuild. Ask anyway, but efficiently.
"It's urgent/EOD/ASAP"	Urgency = higher cost of rework. Clarify FASTER, not less.
"I'll propose and they can correct"	Corrections after implementation cost 10x more than upfront questions.

User Deferral Handling

When user explicitly defers ("skip", "I don't know", "your call", "you decide", "no preference"):

1. Gather context autonomously via explore/oracle
2. Select best practice based on codebase patterns or industry standards
3. Document assumption: "Autonomous decision: [X] - user deferred, based on [rationale]"
4. Proceed without blocking

When user has no preference or cannot decide, select best practice autonomously. Quality is the priority—achieve it through proactive context gathering, not user interrogation.

Protocol

1. Capture & Analyze

Record original verbatim. Identify: unclear items, needed assumptions, open decisions.

2. Context Brokering (CRITICAL)

NEVER burden the user with questions the codebase can answer.

Question Type	Ask User?	Action
"Which project contains X?"	NO	Use explore first
"What patterns exist in the codebase?"	NO	Use explore first
"Where is X implemented?"	NO	Use explore first
"What's the current architecture?"	NO	Use oracle
"What's the tech stack?"	NO	Use explore first
"What's your timeline?"	YES	Ask user (via AskUserQuestion)
"Should we prioritize speed or quality?"	YES	Ask user (via AskUserQuestion)
"What's the scope boundary?"	YES	Ask user (via AskUserQuestion)

The ONLY questions for users are about PREFERENCES, not FACTS.

Explore/Librarian Prompt Guide

Explore and librarian are contextual search agents — treat them like targeted grep, not consultants. Always run in background. Always parallel when independent.

Prompt structure (each field should be substantive, not a single sentence):

• [CONTEXT]: What task you're working on, which files/modules are involved, and what approach you're taking
• [GOAL]: The specific outcome you need — what decision or action the results will unblock
• [DOWNSTREAM]: How you will use the results — what you'll build/decide based on what's found
• [REQUEST]: Concrete search instructions — what to find, what format to return, and what to SKIP

Examples:

// Fact-finding before asking user
Task(subagent_type="explore", prompt="I'm clarifying requirements for a user's auth feature request and need to check what already exists before asking redundant questions. I'll use this to eliminate codebase-answerable questions from my interview. Find: existing auth implementations, login flows, user model structure. Focus on src/ — skip tests. Return file paths with brief descriptions.")

Oracle Consultation

For understanding current architecture before asking scope questions, briefly announce "Consulting Oracle for [reason]" before invocation.

3. Iterative Clarification

Use

AskUserQuestion

for each ambiguity.

Design: Specific > general, Options > open-ended, One at a time, Architecture before details

while ambiguities_remain:
    ask_most_critical() → update() → check_new()

Question Quality Standard

BAD:
  question: "Which approach?"
  options:
    - label: "A"
    - label: "B"

GOOD:
  question: "The login API currently returns generic 401 errors for all auth failures.
    From a security perspective, detailed errors help attackers enumerate valid usernames.
    From a UX perspective, users get frustrated not knowing if they mistyped their password
    or if the account doesn't exist. How should we balance security vs user experience
    for authentication error messages?"
  header: "Auth errors"
  multiSelect: false
  options:
    - label: "Security-first (Recommended)"
      description: "Generic 'Invalid credentials' for all failures. Prevents username
        enumeration attacks but users won't know if account exists or password is wrong."
    - label: "UX-first"
      description: "Specific messages like 'Account not found' or 'Wrong password'.
        Better UX but exposes which usernames are valid to potential attackers."
    - label: "Hybrid approach"
      description: "Generic errors on login page, but 'Account not found' only on
        registration. Balanced but adds implementation complexity."

Rich Context Pattern (For Design Decisions)

For complex technical decisions, provide rich context via markdown BEFORE asking a single AskUserQuestion.

Structure:

1. Current State - What exists now (1-2 sentences)
2. Existing Project Patterns - Relevant code, prior decisions, historical context
3. Change Request Background - Why this decision is needed now
4. Option Analysis - For each option:
   • Behavior description
   • Evaluation table (Security, UX, Maintainability, Adoption)
   • Code impact
5. Recommendation - Your suggested option with rationale
6. AskUserQuestion - Single question with 2-3 options

Rules:

• One question at a time (sequential interview)
• Markdown provides depth, AskUserQuestion provides choice
• Question must be independently understandable (include brief context + "See analysis above")

Question Structure: Context → Tension → Question

For complex decisions, provide markdown analysis BEFORE asking AskUserQuestion:

1. Current situation - What exists now, what's the context
2. Tension/Problem - Why this decision matters, conflicting concerns
3. Existing Project Patterns - Relevant code, prior decisions
4. Option Analysis - For each option:
   • Behavior description
   • Tradeoffs across perspectives (security, UX, maintainability, performance, complexity)
   • Code impact
5. Recommendation - Your suggested option with rationale
6. AskUserQuestion - Single question with options

Rules:

• One question at a time (sequential interview)
• Markdown provides depth, AskUserQuestion provides choice
• Question must be independently understandable (include brief context + "See analysis above")
• Options need descriptions explaining consequences, not just labels

Question Type Selection

Situation	Method	Why
Decision with 2-4 clear options	AskUserQuestion	Provides structured choices
Open-ended/subjective question	Plain text question	Requires free-form answer
Yes/No confirmation	Plain text question	AskUserQuestion is overkill
Complex trade-off decision	Markdown analysis + AskUserQuestion	Deep context + structured choice

Do NOT force AskUserQuestion for open-ended questions. If the answer is open-ended, just ask in plain text.

Vague Answer Clarification

When users respond vaguely ("~is enough", "just do ~", "decide later"):

1. Do NOT accept as-is
2. Ask specific clarifying questions
3. Repeat until clear answer obtained

Note: This applies when the user attempts to answer but is vague. For explicit deferral ("skip", "your call"), see User Deferral Handling in the Protocol section above.

4. Before/After Summary

### Before: "{original}"
### After:
**Goal/Scope/Constraints/Success Criteria**: [...]
| Question | Decision |

5. Save (Optional)

Offer to save to

requirements/

if substantial.

Quick Reference

Category	Ask About
Scope	Included? Excluded?
Behavior	Edge cases? Errors?
Data	Inputs? Outputs? Format?
Constraints	Performance? Compatibility?

Example

Original: "Add a login feature"

Why unclear: "Login" = 10+ implementations. OAuth? Password? Magic link?

Questions (by architectural impact):

1. Auth method? → Password (determines architecture)
2. Registration? → Yes (affects scope)
3. Session? → 24h (security)
4. Password rules? → 8+ chars (detail - ask last)

Result: Password login with registration, 24h session, bcrypt, rate-limited

Common Mistakes

Mistake	Fix
Many questions at once	One concern at a time
Redirecting intent	Refine, don't substitute
Over-clarifying clear requests	Trust specific requirements
Details before architecture	Big decisions first
Skipping clarification due to time pressure	Time pressure = ask fewer but more critical questions, NOT zero
Obeying "no questions" requests	Politely explain: "2 quick questions now save hours later"
AskUserQuestion for open-ended questions	Plain text for open-ended, AskUserQuestion for structured choices
Accepting vague answers ("~is enough")	Ask specific follow-up until clear

Rules

1. No assumptions - Ask, don't assume
2. Preserve intent - Refine, don't redirect
3. Minimal questions - Only what's needed
4. Respect answers - Accept decisions
5. Show transformation - Always before/after
6. Interview persistence - Continue until YOU have no questions left. Not after 2-3 questions. Keep clarifying until every ambiguity is resolved. Deferral fallback: If user defers a decision, gather context autonomously (explore/oracle), document your autonomous choice with rationale, and proceed.
