Implications for Coditect Autonomous Development Platform

Source: Video transcript - AI-assisted development experiment
Analysis Date: January 2026
Relevance: CRITICAL - Validates core Coditect architecture decisions


Executive Summary

This experiment provides empirical evidence for architectural decisions embedded in the Coditect PRD Standards. The key finding—that intent preservation, not model intelligence, determines build quality—directly validates Coditect's Intent Understanding Framework and reveals a critical gap in current AI development tools that Coditect can exploit as competitive differentiation.

2. Key Findings

Finding 1: Planning Mode is a "Powerful Planning Filter"

The Claude Code planning step normalizes all inputs, smoothing out differences between PRDs regardless of quality. This has dual implications:

Positive: Users don't need expensive models for PRD generation
Negative: Planning mode also drops requirements silently

"The planning step was dropping 20 to 30% of my requirements. Not because they weren't clear, not because they were unreasonable, they were just lost."

Finding 2: Intent Preservation is the Critical Variable

When the author added explicit instructions to "carry intent through" and "explain why each one matters," results diverged dramatically:

ModelScore WITHOUT intent instructionScore WITH intent instruction
GPT-5.2 ThinkingMid-80sMid-80s (no change)
Opus 4.5Mid-80s99%

12-point gap from next closest model when intent was explicitly preserved.

Finding 3: Silent Losses at Each Handoff

The "gap between your best idea and what gets built" occurs at multiple stages:

┌─────────────┐    LOSS #1     ┌─────────────┐    LOSS #2     ┌─────────────┐    LOSS #3     ┌─────────────┐
│ INTENT │──────────────▶│ PRD │──────────────▶│ PLAN │──────────────▶│ BUILD │
│ DOCUMENT │ Intent lost │ │ Requirements │ │ Features │ │
│ │ in PRD │ │ dropped in │ │ missing in │ │
│ │ translation │ │ planning │ │ execution │ │
└─────────────┘ └─────────────┘ └─────────────┘ └─────────────┘

Finding 4: Verification Loop Recovers Lost Requirements

Planning PassMissing ItemsRecovery Rate
First pass18 itemsBaseline
Second pass8 items56% recovery
Third passOnly ambiguous items~90%+ recovery

Pattern discovered:

  1. Generate plan
  2. Compare plan against PRD
  3. Find everything missing → create fallout list
  4. Update plan to include missing items
  5. Repeat until stable

4. Coditect Impact Analysis

4.1 Validation of PRD Standards Template

The article directly validates the following sections of the Coditect PRD Standards:

Intent Understanding Framework (Section 2)

Article Quote:

"The issue isn't how smart the model is, the issue is how much intent survives the translation."

Coditect Solution: The Intent Block template captures:

  • Strategic Context (the "why")
  • Success/Failure indicators
  • Implicit assumptions
  • Anti-requirements

This ensures intent is explicitly documented rather than implicitly assumed.

Disambiguation Framework (Section 3)

Article Quote:

"The remaining items were things that I hadn't really specified all that well anyway, they were pretty kind of ambiguous."

Coditect Solution: Ambiguity scoring (0.0-1.0) with escalation triggers ensures ambiguous requirements are resolved before planning, not lost during planning.

AI Agent Interpretation Guide (Section 6)

Article Quote:

"They should be able to evaluate against the original request... It's kind of surprising that they're not doing that."

Coditect Solution: Rule 5 (Document Everything) and the verification loop requirement ensure agents validate against source documents at each stage.

4.2 Required Coditect Architecture Enhancements

Based on this analysis, Coditect should implement:

Enhancement 1: Planning Verification Service

┌─────────────────────────────────────────────────────────────┐
│ PLANNING VERIFICATION SERVICE │
├─────────────────────────────────────────────────────────────┤
│ │
│ INPUT: PRD + Generated Plan │
│ │
│ PROCESS: │
│ 1. Extract all requirements from PRD │
│ 2. Extract all planned items from Plan │
│ 3. Diff: PRD requirements - Plan items = FALLOUT LIST │
│ 4. Score coverage percentage │
│ 5. If coverage < 95%: ITERATE │
│ 6. If coverage < 80%: ESCALATE to human │
│ │
│ OUTPUT: Verified Plan + Fallout Report + Coverage Score │
│ │
└─────────────────────────────────────────────────────────────┘

Enhancement 2: Intent Survival Tracking

@dataclass
class IntentSurvivalMetrics:
"""Track intent through the development pipeline"""

original_intent_items: int # From intent document
prd_intent_items: int # Captured in PRD
plan_intent_items: int # Made it to plan
build_intent_items: int # Implemented in code

@property
def prd_survival_rate(self) -> float:
return self.prd_intent_items / self.original_intent_items

@property
def plan_survival_rate(self) -> float:
return self.plan_intent_items / self.prd_intent_items

@property
def build_survival_rate(self) -> float:
return self.build_intent_items / self.plan_intent_items

@property
def total_survival_rate(self) -> float:
return self.build_intent_items / self.original_intent_items

def identify_loss_stage(self) -> str:
"""Find where most intent is lost"""
losses = {
"PRD Translation": 1 - self.prd_survival_rate,
"Planning": 1 - self.plan_survival_rate,
"Build": 1 - self.build_survival_rate
}
return max(losses, key=losses.get)

Enhancement 3: Fallout List Automation

After each planning phase, automatically generate:

## FALLOUT REPORT - Planning Pass #1

### Missing Requirements (18 items)

| Req ID | Requirement | PRD Section | Severity |
|--------|-------------|-------------|----------|
| FR-012 | Word of the day integration | 4.3.12 | MEDIUM |
| FR-015 | Sound effects on lookup | 4.3.15 | LOW |
| FR-018 | Auto-dismiss behavior | 4.3.18 | HIGH |
| ... | ... | ... | ... |

### Coverage Analysis
- **PRD Requirements:** 67
- **Planned Items:** 49
- **Coverage:** 73.1%
- **Status:** ⚠️ BELOW THRESHOLD (95%)

### Recommended Action
Iterate planning with fallout list appended to context.

4.3 Token Economics Impact

The article reveals that model cost ≠ output quality in planning-mediated workflows:

ModelCost (relative)Output QualityImplication
GPT-5.2 Instant1x~85%Use for PRD generation
GPT-5.2 Pro100x+~85%Wasteful for PRD generation
Opus 4.5 (planning)10xNormalizes all inputsUse for planning orchestration

Coditect Token Strategy:

  • Use cost-effective models for PRD generation
  • Invest tokens in verification loops rather than expensive base models
  • The 3-pass verification pattern costs ~3x tokens but recovers 90%+ of lost requirements

5. Actionable Recommendations

Immediate (Week 1-2)

  1. Add fallout list generation to planning phase
  2. Implement 3-pass verification as default behavior
  3. Track intent survival metrics in development dashboard

Short-term (Month 1)

  1. Update PRD Standards template with explicit intent-carrying instructions
  2. Create Intent Preservation Score as a first-class metric
  3. Build automated PRD ↔ Plan diff tool

Medium-term (Quarter 1)

  1. Train custom model for intent extraction from voice memos
  2. Implement real-time verification during planning (not just post-hoc)
  3. Create "Intent Debugger" showing where losses occur

6. Key Quotes for Reference

"The gap between your best idea and what gets built isn't about using GPT-5 Pro versus 5.2 instant. It's about the silent losses at each handoff."

"The planning step was dropping 20 to 30% of my requirements. Not because they weren't clear, not because they were unreasonable, they were just lost."

"Your intent is the actual you in all of this."

"What actually matters here is getting your intent to survive the journey and then verifying that nothing got dropped along the way."

"They should be able to evaluate against the original request... It's kind of surprising that they're not doing that."


7. Conclusion

This experiment provides empirical validation for Coditect's core architectural decisions:

  1. Intent preservation > model intelligence - The Intent Understanding Framework addresses this
  2. Silent losses are the real enemy - Disambiguation and verification loops address this
  3. Verification against source is not standard - This is Coditect's competitive advantage
  4. Process beats model selection - Multi-pass verification recovers lost requirements

The finding that current AI development tools (Claude Code, Cursor, etc.) do not verify against original requirements represents a significant market opportunity for Coditect in regulated industries where requirement traceability is mandatory.
