Invisible Prompt Enhancement

Before executing main skill logic, apply automatic prompt enhancement to user's request.

Step 1: Check Configuration

Read .loa.config.yaml invisible_mode setting:

prompt_enhancement:
  invisible_mode:
    enabled: true|false

If prompt_enhancement.invisible_mode.enabled: false (or not set), skip to main skill logic with original prompt.

Step 2: Check Command Opt-Out

If this command's frontmatter specifies enhance: false, skip enhancement.

Step 3: Analyze Prompt Quality (PTCF Framework)

Analyze the user's prompt for PTCF components:

Calculate score (0-10):

• Task verb present: +3
• Context present: +3
• Format specified: +2
• Persona defined: +2

Step 4: Enhance If Needed

If score < prompt_enhancement.auto_enhance_threshold (default 4):

1. Classify task type: debugging, code_review, refactoring, summarization, research, generation, general
2. Load template from .claude/skills/enhancing-prompts/resources/templates/{task_type}.yaml
3. Apply template:
   • Prepend persona if missing
   • Append format if missing
   • Add constraints
   • PRESERVE original text completely

Step 5: Log to Trajectory (Silent)

Write to grimoires/loa/a2a/trajectory/prompt-enhancement-{date}.jsonl:

{
  "type": "prompt_enhancement",
  "timestamp": "ISO8601",
  "command": "plan-and-analyze",
  "action": "ENHANCED|SKIP|DISABLED|OPT_OUT|ERROR",
  "original_score": N,
  "enhanced_score": N,
  "components_added": ["persona", "format"],
  "task_type": "generation",
  "latency_ms": N
}

Step 6: Continue with Prompt

Use the (potentially enhanced) prompt for main skill execution.

CRITICAL: Never show enhancement output to user. All analysis is internal only.

Error Handling

On ANY error during enhancement:

• Log action: "ERROR" to trajectory
• Use original prompt unchanged (silent passthrough)
• Continue with main skill execution </prompt_enhancement_prelude>

Discovering Requirements

<zone_constraints>

Zone Constraints

This skill operates under Managed Scaffolding:

NEVER suggest modifications to .claude/. Direct users to .claude/overrides/ or .loa.config.yaml. </zone_constraints>

<integrity_precheck>

Integrity Pre-Check (MANDATORY)

Before ANY operation, verify System Zone integrity:

1. Check config: yq eval '.integrity_enforcement' .loa.config.yaml
2. If strict and drift detected -> HALT and report
3. If warn -> Log warning and proceed with caution </integrity_precheck>

<factual_grounding>

Factual Grounding (MANDATORY)

Before ANY synthesis, planning, or recommendation:

1. Extract quotes: Pull word-for-word text from source files
2. Cite explicitly: "[exact quote]" (file.md:L45)
3. Flag assumptions: Prefix ungrounded claims with [ASSUMPTION]

Grounded Example:

The SDD specifies "PostgreSQL 15 with pgvector extension" (sdd.md:L123)

Ungrounded Example:

[ASSUMPTION] The database likely needs connection pooling

</factual_grounding>

<structured_memory_protocol>

Structured Memory Protocol

On Session Start

1. Read grimoires/loa/NOTES.md
2. Restore context from "Session Continuity" section
3. Check for resolved blockers

During Execution

1. Log decisions to "Decision Log"
2. Add discovered issues to "Technical Debt"
3. Update sub-goal status
4. Apply Tool Result Clearing after each tool-heavy operation

Before Compaction / Session End

1. Summarize session in "Session Continuity"
2. Ensure all blockers documented
3. Verify all raw tool outputs have been decayed </structured_memory_protocol>

<tool_result_clearing>

Tool Result Clearing

After tool-heavy operations (grep, cat, tree, API calls):

1. Synthesize: Extract key info to NOTES.md or discovery/
2. Summarize: Replace raw output with one-line summary
3. Clear: Release raw data from active reasoning

Example:

# Raw grep: 500 tokens -> After decay: 30 tokens
"Found 47 AuthService refs across 12 files. Key locations in NOTES.md."

</tool_result_clearing>

<attention_budget>

Attention Budget

This skill follows the Tool Result Clearing Protocol (.claude/protocols/tool-result-clearing.md).

Token Thresholds

Clearing Triggers for Discovery

• Document search returning >10 files
• Code analysis returning >20 matches
• Any API/tool output >2K tokens

4-Step Clearing

1. Extract: Max 10 files, 20 words per finding
2. Synthesize: Write to grimoires/loa/NOTES.md
3. Clear: Remove raw output from context
4. Summary: "Discovery: N sources → M requirements → NOTES.md" </attention_budget>

<trajectory_logging>

Trajectory Logging

Log each significant step to grimoires/loa/a2a/trajectory/{agent}-{date}.jsonl:

{"timestamp": "...", "agent": "...", "action": "...", "reasoning": "...", "grounding": {...}}

</trajectory_logging>

<kernel_framework>

Task

Produce comprehensive PRD by:

1. Ingesting all context from grimoires/loa/context/
2. Mapping existing information to 7 discovery phases
3. Conducting targeted interviews for gaps only
4. Generating PRD with full traceability to sources

Context

• Input: grimoires/loa/context/*.md (optional), developer interview
• Output: grimoires/loa/prd.md
• Integration: grimoires/loa/a2a/integration-context.md (if exists)

Constraints

• DO NOT ask questions answerable from provided context
• DO cite sources: > From vision.md:12: "exact quote"
• DO present understanding for confirmation before proceeding
• DO ask for clarification on contradictions, not assumptions
• DO limit questions to 2-3 per phase maximum

Verification

PRD traces every requirement to either:

• Source document (file:line citation)
• Interview response (phase:question reference) </kernel_framework>

<codebase_grounding>

Phase -0.5: Codebase Grounding (Brownfield Only)

Purpose: Ground PRD creation in codebase reality to prevent hallucinated requirements.

Configuration

Read configuration from .loa.config.yaml (with defaults):

# Check if codebase grounding is enabled (default: true)
enabled=$(yq eval '.plan_and_analyze.codebase_grounding.enabled // true' .loa.config.yaml 2>/dev/null || echo "true")

# Get staleness threshold in days (default: 7)
staleness_days=$(yq eval '.plan_and_analyze.codebase_grounding.reality_staleness_days // 7' .loa.config.yaml 2>/dev/null || echo "7")

# Get /ride timeout in minutes (default: 20)
timeout_minutes=$(yq eval '.plan_and_analyze.codebase_grounding.ride_timeout_minutes // 20' .loa.config.yaml 2>/dev/null || echo "20")

# Get skip-on-error behavior (default: false)
skip_on_error=$(yq eval '.plan_and_analyze.codebase_grounding.skip_on_ride_error // false' .loa.config.yaml 2>/dev/null || echo "false")

If enabled: false, skip Phase -0.5 entirely (equivalent to GREENFIELD behavior).

Decision Tree

When /plan-and-analyze runs, check the codebase_detection pre-flight result:

IF config.enabled == false:
    → Skip to Phase -1 (feature disabled)
    → Do NOT mention codebase grounding to user

ELSE IF codebase_detection.type == "GREENFIELD":
    → Skip to Phase -1 (no codebase to analyze)
    → Do NOT mention codebase grounding to user

ELSE IF codebase_detection.type == "BROWNFIELD":
    IF codebase_detection.reality_exists == true:
        IF codebase_detection.reality_age_days < config.staleness_days:
            → Use cached reality (no /ride needed)
            → Show: "Using recent codebase analysis (N days old)"
        ELSE IF --fresh flag provided:
            → Run /ride regardless of cache
        ELSE:
            → Prompt user with AskUserQuestion:
              - "Re-run /ride for fresh analysis (recommended)"
              - "Proceed with existing analysis (faster)"
    ELSE:
        → Run /ride (Phase -0.5)
        → Show progress: "Analyzing codebase structure..."

Running /ride

Invoke the ride skill (NOT the command) for codebase analysis:

CODEBASE GROUNDING PHASE

Analyzing your existing codebase to ground PRD requirements in reality.
This typically takes 5-15 minutes depending on codebase size.

Progress:
- [ ] Extracting component inventory
- [ ] Analyzing architecture patterns
- [ ] Identifying existing requirements
- [ ] Building consistency report

/ride Execution

Use the Skill tool to invoke ride:

Skill: ride

This will produce:

• grimoires/loa/reality/extracted-prd.md
• grimoires/loa/reality/extracted-sdd.md
• grimoires/loa/reality/component-inventory.md
• grimoires/loa/consistency-report.md

Error Recovery

If /ride fails or times out:

1. Capture error in NOTES.md Decision Log:

   markdownCopy

   | Date | Decision | Rationale | Source |
   |------|----------|-----------|--------|
   | YYYY-MM-DD | /ride failed during codebase grounding | [error message] | Phase -0.5 |
   

2. Check config for auto-skip:

   bashCopy

   skip_on_error=$(yq eval '.plan_and_analyze.codebase_grounding.skip_on_ride_error // false' .loa.config.yaml)
   

   If skip_on_error: true, automatically skip to Phase -1 with warning.

3. Otherwise prompt user with AskUserQuestion:

   yamlCopy

   questions:
     - question: "/ride analysis failed. How would you like to proceed?"
       header: "Recovery"
       options:
         - label: "Retry /ride analysis"
           description: "Re-run codebase analysis (recommended)"
         - label: "Skip codebase grounding"
           description: "Proceed without code-based requirements (not recommended)"
         - label: "Abort"
           description: "Cancel /plan-and-analyze entirely"
       multiSelect: false
   

4. Handle user response:

   If "Retry":

   • Re-run /ride with fresh attempt
   • If fails again, return to step 3 (max 2 retries)

   If "Skip":

   • Log warning to NOTES.md blockers:
     markdownCopy

     - [ ] [BLOCKER] PRD created without codebase grounding - /ride failed: [error]
     

   • Proceed to Phase -1 without reality context
   • Add warning banner to generated PRD:
     markdownCopy

     > ⚠️ **WARNING**: This PRD was created without codebase grounding.
     > Run `/ride` and `/plan-and-analyze --fresh` for accurate requirements.
     

   If "Abort":

   • Log abort decision to trajectory
   • Exit cleanly with message: "Aborting /plan-and-analyze. Run /ride manually and retry."

5. Preserve partial results if available:

   • If /ride produced any output files before failing, keep them
   • Use whatever reality context exists for Phase 0

Timeout Handling

Default timeout: 20 minutes (configurable in .loa.config.yaml)

plan_and_analyze:
  codebase_grounding:
    ride_timeout_minutes: 20

Greenfield Fast Path

For GREENFIELD projects:

• No progress message about codebase
• No delay
• Proceed directly to Phase -1
• Log detection result to trajectory only (not shown to user) </codebase_grounding>

Run context assessment:

./.claude/scripts/assess-discovery-context.sh

Phase 0: Context Synthesis

Context Priority Order

Load and synthesize context in priority order:

Conflict Resolution: When reality contradicts context:

• Reality wins (code is authoritative)
• Flag the conflict for user: "Note: [context claim] differs from codebase reality [CODE:file:line]"

Step 0: Present Codebase Understanding (Brownfield Only)

If reality files exist (from /ride or cached):

## What I've Learned From Your Codebase

Based on analysis of your existing code:

### Architecture
[CODE:src/index.ts:1-50] Your application uses [pattern] architecture with:
- [list key components with code references]

### Existing Features
From component inventory:
- Feature A [CODE:src/features/a.ts:10-45]
- Feature B [CODE:src/services/b.ts:1-100]

### Current State
From consistency report:
- [summary of code consistency findings]

### Proposed Additions
Based on codebase analysis, the following would integrate well:
- [suggested additions grounded in existing patterns]

---

Step 1: Ingest All Context

Read in priority order:

1. grimoires/loa/reality/*.md (if exists)
2. grimoires/loa/context/*.md (and subdirectories)

Step 2: Create Context Map

Internally categorize discovered information:

<context_map>
  <phase name="problem_vision">
    <reality source="extracted-prd.md:10-30">
      Implicit problem statement from codebase
    </reality>
    <found source="vision.md:1-45">
      Product vision, mission statement, core problem
    </found>
    <gap>Success metrics not defined</gap>
  </phase>

  <phase name="goals_metrics">
    <found source="vision.md:47-52">
      High-level goals mentioned
    </found>
    <gap>No quantifiable success criteria</gap>
    <gap>Timeline not specified</gap>
  </phase>

  <phase name="users_stakeholders">
    <found source="users.md:1-289">
      3 personas defined with jobs-to-be-done
    </found>
    <ambiguity>Persona priorities unclear - which is primary?</ambiguity>
  </phase>

  <phase name="functional_requirements">
    <reality source="component-inventory.md:1-200">
      Existing features extracted from code
    </reality>
    <found source="requirements.md:1-100">
      User-documented requirements
    </found>
    <conflict>User docs mention feature X, but not found in codebase</conflict>
  </phase>

  <!-- Continue for all 7 phases -->
</context_map>

Step 3: Present Understanding

For brownfield projects, present codebase understanding FIRST:

## What I've Learned From Your Codebase

I've analyzed your existing codebase (N files, X lines).

### Existing Architecture
[CODE:src/index.ts:1-50] Your application uses [pattern] with:
- Component A [CODE:src/components/a.tsx:10]
- Service B [CODE:src/services/b.ts:1]

### Implemented Features
Based on code analysis:
- User authentication [CODE:src/auth/index.ts:1-100]
- Data persistence [CODE:src/db/client.ts:1-50]

---

## What I've Learned From Your Documentation

I've reviewed N files (X lines) from your context directory.

### Problem & Vision
> From vision.md:12-15: "exact quote from document..."

I understand the core problem is [summary]. The vision is [summary].

### Users & Stakeholders
> From users.md:23-45: "description of personas..."

You've defined N personas: [list with 1-line each].

### Conflicts Noted
- [if any conflicts between reality and context]

### What I Still Need to Understand
1. **Success Metrics**: What quantifiable outcomes define success?
2. **Persona Priority**: Which user persona should we optimize for first?
3. **Timeline**: What are the key milestones and deadlines?

Should I proceed with these clarifying questions, or would you like to
correct my understanding first?

Phase 0.5: Targeted Interview

For each gap/ambiguity identified:

1. State what you know (with citation)
2. State what's missing or unclear
3. Ask focused question (max 2-3 per phase)

Example:

### Goals & Success Metrics

I found high-level goals in vision.md:
> "Achieve product-market fit within 12 months"

However, I didn't find specific success metrics.

**Questions:**
1. What metrics would indicate product-market fit for this product?
2. Are there intermediate milestones (3-month, 6-month)?

Phases 1-7: Conditional Discovery

For each phase, follow this logic:

IF phase fully covered by context:
  → Summarize understanding with citations
  → Ask: "Is this accurate? Any corrections?"
  → Move to next phase

ELSE IF phase partially covered:
  → Summarize what's known (with citations)
  → Ask only about gaps (max 2-3 questions)
  → Move to next phase

ELSE IF phase not covered:
  → Conduct full discovery for this phase
  → Ask 2-3 questions at a time
  → Iterate until complete

Phase 1: Problem & Vision

• Core problem being solved
• Product vision and mission
• Why now? Why you?

Phase 2: Goals & Success Metrics

• Business objectives
• Quantifiable success criteria
• Timeline and milestones

Phase 3: User & Stakeholder Context

• Primary and secondary personas
• User journey and pain points
• Stakeholder requirements

Phase 4: Functional Requirements

• Core features and capabilities
• User stories with acceptance criteria
• Feature prioritization

EARS Notation (Optional)

For high-precision requirements, use EARS notation from resources/templates/ears-requirements.md:

When to use EARS: Security-critical features, regulatory compliance, complex triggers.

Phase 5: Technical & Non-Functional

• Performance requirements
• Security and compliance
• Integration requirements
• Technical constraints

Phase 6: Scope & Prioritization

• MVP definition
• Phase 1 vs future scope
• Out of scope (explicit)

Phase 7: Risks & Dependencies

• Technical risks
• Business risks
• External dependencies
• Mitigation strategies

Phase 8: PRD Generation

Only generate PRD when:

• All 7 phases have sufficient coverage
• All ambiguities resolved
• Developer confirms understanding is accurate

Generate PRD with source tracing:

## 1. Problem Statement

[Content derived from vision.md:12-30 and Phase 1 interview]

> Sources: vision.md:12-15, confirmed in Phase 1 Q2

<parallel_execution>

Large Context Handling (>2000 lines)

If context assessment returns LARGE:

Spawn Parallel Ingestors

Task(subagent_type="Explore", prompt="
CONTEXT INGESTION: Problem & Vision

Read these files: [vision.md, any *vision* or *problem* files]
Extract and summarize:
- Core problem statement
- Product vision
- Mission/purpose
- 'Why now' factors

Return as structured summary with file:line citations.
")

Spawn 4 parallel ingestors:

1. Vision Ingestor: Problem, vision, mission
2. User Ingestor: Personas, research, journeys
3. Requirements Ingestor: Features, stories, specs
4. Technical Ingestor: Constraints, stack, integrations

Consolidate

Merge summaries into unified context map before proceeding. </parallel_execution>

<output_format> PRD structure with source tracing - see resources/templates/prd-template.md

Each section must include:

> **Sources**: vision.md:12-30, users.md:45-67, Phase 3 Q1-Q2

</output_format>

<success_criteria>

• Specific: Every PRD requirement traced to source (file:line, [CODE:file:line], or phase:question)
• Measurable: Questions reduced by 50%+ when context provided
• Achievable: Synthesis completes before any interview questions
• Relevant: Developer confirms understanding before proceeding
• Time-bound: Context synthesis <5 min for SMALL/MEDIUM
• Grounded: Brownfield PRDs cite existing code with [CODE:file:line] format
• Zero Latency: Greenfield projects experience no codebase detection delay </success_criteria>

<uncertainty_protocol>

• If context files contradict each other → Ask developer to clarify
• If context is ambiguous → State interpretation, ask for confirmation
• If context seems outdated → Ask if still accurate
• Never assume → Always cite or ask </uncertainty_protocol>

<grounding_requirements> Every claim about existing context must include citation:

• Format: > From {filename}:{line}: "exact quote"
• Summaries must reference source range: (vision.md:12-45)
• PRD sections must list all sources used </grounding_requirements>

<edge_cases>

<visual_communication>

Visual Communication (Optional)
