Generating Validation Reports

Generate validation and audit reports following repository standards for naming, progressive writing, and UUID-based execution tracking.

When This Skill Loads

This Skill auto-loads for checker and fixer agents that need to generate validation reports in generated-reports/.

Core Knowledge

Report File Naming Pattern

All reports follow the 4-part pattern:

{agent-family}__{uuid-chain}__{YYYY-MM-DD--HH-MM}__{type}.md

Components:

• {agent-family}: Agent name WITHOUT -checker suffix (e.g., docs, ayokoding-web, plan)
• {uuid-chain}: Execution hierarchy as 6-char hex UUIDs separated by underscores
• {YYYY-MM-DD--HH-MM}: UTC+7 timestamp (double dash between date and time)
• {type}: Report type (audit, validation, fix)

Examples:

generated-reports/docs__a1b2c3__2026-01-03--14-30__audit.md
generated-reports/plan__d4e5f6__2026-01-03--15-00__validation.md
generated-reports/ayokoding-facts__a1b2c3_d4e5f6__2026-01-03--16-45__audit.md

UUID Generation

Generate 6-character hexadecimal UUID at agent startup:

MY_UUID=$(uuidgen | tr '[:upper:]' '[:lower:]' | head -c 6)
# Example output: a1b2c3

Why 6 characters?

• 16^6 = 16,777,216 combinations
• Collision probability for 1000 parallel executions: ~0.003%
• Short for readability, long enough for uniqueness

UUID Chain Logic

Scope-based execution tracking enables parent-child hierarchy:

Tracking File Pattern: generated-reports/.execution-chain-{scope}

Startup Logic:

# 1. Generate own UUID
MY_UUID=$(uuidgen | tr '[:upper:]' '[:lower:]' | head -c 6)

# 2. Determine scope (from EXECUTION_SCOPE or default to agent-family)
SCOPE="${EXECUTION_SCOPE:-docs}"

# 3. Read parent chain from scope tracking file
CHAIN_FILE="generated-reports/.execution-chain-${SCOPE}"
if [ -f "$CHAIN_FILE" ]; then
  read PARENT_TIME PARENT_CHAIN < "$CHAIN_FILE"
  CURRENT_TIME=$(date +%s)
  TIME_DIFF=$((CURRENT_TIME - PARENT_TIME))

  # If parent is recent (< 5 min), append to chain
  if [ $TIME_DIFF -lt 300 ]; then
    UUID_CHAIN="${PARENT_CHAIN}_${MY_UUID}"
  else
    UUID_CHAIN="$MY_UUID"  # Start new chain
  fi
else
  UUID_CHAIN="$MY_UUID"  # First execution
fi

# 4. Write own chain to tracking file
echo "$(date +%s) $UUID_CHAIN" > "$CHAIN_FILE"

Chain Examples:

• a1b2c3 - Root execution (no parent)
• a1b2c3_d4e5f6 - Child of a1b2c3
• a1b2c3_d4e5f6_g7h8i9 - Grandchild (2 levels deep)

UTC+7 Timestamp Generation

Generate timestamp in UTC+7 timezone:

TIMESTAMP=$(TZ='Asia/Jakarta' date +"%Y-%m-%d--%H-%M")
# Example output: 2026-01-03--14-30

Format: YYYY-MM-DD--HH-MM (double dash between date and time for filesystem compatibility)

Progressive Writing Methodology

CRITICAL REQUIREMENT: All checker agents MUST write findings progressively, not buffer and write once at end.

Why? Context compaction during long validation runs can lose buffered findings. Progressive writing ensures audit history survives.

Implementation Pattern:

Step 0: Initialize Report File

- Generate UUID and chain
- Create report file immediately
- Write header with "In Progress" status

Steps 1-N: Validate Content

- For each validation check:
  1. Perform validation
  2. Immediately write finding to report file (append mode)
  3. Continue to next check
- DO NOT buffer findings in memory

Final Step: Finalize Report

- Update status from "In Progress" to "Complete"
- Add summary statistics
- File already contains all findings from progressive writing

Report Template Structure

Initial Header (Step 0):

# Validation Report: [Agent Name]

**Status**: In Progress
**Agent**: [agent-name]
**Scope**: [scope-description]
**Timestamp**: [YYYY-MM-DD--HH-MM UTC+7]
**UUID Chain**: [uuid-chain]

---

## Findings

[Findings will be written progressively during validation]

Progressive Findings (Steps 1-N):

### Finding [N]: [Title]

**File**: path/to/file.md
**Line**: 123
**Criticality**: HIGH
**Category**: [category-name]

**Issue**: [Description of what's wrong]

**Recommendation**: [How to fix it]

---

Final Summary (Last Step):

## Summary

**Total Findings**: [N]

- CRITICAL: [count]
- HIGH: [count]
- MEDIUM: [count]
- LOW: [count]

**Status**: Complete
**Completed**: [YYYY-MM-DD--HH-MM UTC+7]

Scope Definitions

Common scopes for execution tracking:

Tool Requirements

Agents using this Skill MUST have:

• Write tool: Required for creating report files
• Bash tool: Required for UUID generation and UTC+7 timestamps

Usage Example

Checker Agent Startup:

# Generate UUID and determine chain
MY_UUID=$(uuidgen | tr '[:upper:]' '[:lower:]' | head -c 6)
SCOPE="${EXECUTION_SCOPE:-docs}"
CHAIN_FILE="generated-reports/.execution-chain-${SCOPE}"

if [ -f "$CHAIN_FILE" ]; then
  read PARENT_TIME PARENT_CHAIN < "$CHAIN_FILE"
  CURRENT_TIME=$(date +%s)
  TIME_DIFF=$((CURRENT_TIME - PARENT_TIME))

  if [ $TIME_DIFF -lt 300 ]; then
    UUID_CHAIN="${PARENT_CHAIN}_${MY_UUID}"
  else
    UUID_CHAIN="$MY_UUID"
  fi
else
  UUID_CHAIN="$MY_UUID"
fi

echo "$(date +%s) $UUID_CHAIN" > "$CHAIN_FILE"

# Generate timestamp
TIMESTAMP=$(TZ='Asia/Jakarta' date +"%Y-%m-%d--%H-%M")

# Create report filename
REPORT_FILE="generated-reports/docs__${UUID_CHAIN}__${TIMESTAMP}__audit.md"

# Initialize report (progressive writing starts here)
cat > "$REPORT_FILE" << 'REPORT_HEADER'
# Validation Report: docs__checker

**Status**: In Progress
**Agent**: docs__checker
**Scope**: Documentation validation
**Timestamp**: [timestamp]
**UUID Chain**: [uuid-chain]

## Findings

REPORT_HEADER

# Continue with validation, writing findings progressively...

Key Principles

1. Generate UUID early: First thing at agent startup
2. Initialize report immediately: Before any validation begins
3. Write progressively: Append findings as you discover them
4. Use UTC+7 timestamps: Consistent timezone across all reports
5. Follow 4-part naming: Agent-family, UUID chain, timestamp, type
6. Track execution scope: Enable parent-child hierarchy for workflows
7. Require Write+Bash tools: Essential for report generation

Common Mistakes to Avoid

❌ Buffering findings: Don't collect all findings in memory and write at end (context compaction risk) ✅ Progressive writing: Write each finding immediately after discovery

❌ Wrong timestamp format: Don't use YYYY-MM-DD HH:MM (spaces in filenames) ✅ Correct format: Use YYYY-MM-DD--HH-MM (double dash separator)

❌ Missing UUID chain: Don't use timestamp alone for uniqueness ✅ UUID chain: Enables parallel execution without collisions

❌ Generic scope: Don't use same scope for all agents ✅ Specific scope: Use agent-family or language-specific scope

Integration with Other Skills

Works alongside:

• wow__assessing-criticality-confidence - Categorize findings by severity
• wow__applying-maker-checker-fixer - Fixer agents read these reports
• Domain Skills (apps__ayokoding-web__developing-content, etc.) - Provide validation criteria

Benefits

1. Parallelization-safe: UUID chains prevent file collisions
2. Traceable: Can track parent-child execution hierarchy
3. Resilient: Progressive writing survives context compaction
4. Consistent: Standard naming across all checker agents
5. Debuggable: Timestamp and UUID chain aid troubleshooting
