Meta Compound Analyze Command

You are an elite compound engineering analyst specializing in extracting systematic improvement opportunities from PR retrospectives. Your role is to analyze compound_learnings data generated by /clean-branch, identify recurring patterns, cluster similar suggestions, track quality trends, and generate a prioritized improvement roadmap.

Arguments: $ARGUMENTS

Overview

This command analyzes PR retrospective data to identify:

•Theme patterns: Which quality themes appear most frequently across PRs
•Recurring suggestions: Similar improvement ideas suggested multiple times
•Quality trends: Are review iterations, fix commits, and comments trending up or down?
•Priority improvements: Highest-ROI suggestions ranked by frequency × confidence × impact

Data Source: compound_learnings[] array in meta/telemetry.json, generated by /clean-branch after each PR merge.

Workflow

Phase 1: Parse Arguments and Locate Data

bash

PLUGIN_DIR="$HOME/.claude/plugins/marketplaces/psd-claude-coding-system/plugins/psd-claude-coding-system"
META_DIR="$PLUGIN_DIR/meta"
TELEMETRY_FILE="$META_DIR/telemetry.json"

# Parse arguments
SINCE_DAYS=""
MIN_CONFIDENCE=""
OUTPUT_FILE=""

# Parse space-separated arguments
set -- $ARGUMENTS

Phase 2: Read and Validate Compound Learnings Data

Use the Read tool to examine the telemetry file:

bash

# Read telemetry.json to check for compound_learnings array

Expected structure:

json

  "version": "1.1.0",
  "started": "2025-11-30",
  "executions": [...],
  "compound_learnings": [
    {

Validation:

bash

Extract and aggregate theme mentions across all PRs:

Phase 4: Suggestion Clustering Analysis

Group similar suggestions and rank by occurrence:

Phase 5: Quality Trend Tracking

Analyze quality metrics over time:

  fi

  rm -f /tmp/trends.json

echo ""

Phase 6: Priority Ranking & Recommendations

Generate prioritized improvement backlog:

bash

echo "=== RECOMMENDED ACTIONS ==="
echo ""

if command -v jq >/dev/null 2>&1; then
  # Re-extract clustered suggestions with priority scoring
  cat "$TELEMETRY_FILE" | jq -r '
    .compound_learnings // [] |
    map(.suggestions // []) |
    flatten |
    group_by(.suggestion) |
    map({
      suggestion: .[0].suggestion,
      type: .[0].type,
      confidence: .[0].confidence,
      implementation: .[0].implementation,
      occurrences: length,
      priority_score: (
        length *
        (if .[0].confidence == "high" then 3 elif .[0].confidence == "medium" then 2 else 1 end)
      )
    }) |
    sort_by(-.priority_score) |
    .[0:5]
  ' > /tmp/priorities.json

  # Display top 5 recommendations
  cat /tmp/priorities.json | jq -r 'to_entries | .[] |
    "\(.key + 1). **\(.value.suggestion)**\n" +
    "   - Occurrences: \(.value.occurrences) PRs\n" +
    "   - Confidence: \(.value.confidence)\n" +
    "   - Type: \(.value.type)\n" +
    "   - Implementation: \(.value.implementation)\n" +
    "   - Priority Score: \(.value.priority_score)\n"
  '

  rm -f /tmp/priorities.json
else
  echo "⚠️  jq not available - skipping priority ranking"
fi

echo ""
echo "---"
echo "Analysis complete. Use /meta-implement to apply high-priority suggestions."

Phase 7: Output to File (if --output specified)

All analysis output from Phases 2-6 should be captured. If --output is specified, pipe the output to tee:

bash

# Wrap analysis logic in a function (already executed above in Phases 2-6)
# If OUTPUT_FILE was specified, the output has been tee'd to the file

if [ -n "$OUTPUT_FILE" ]; then
  echo ""
  echo "---"
  echo "✓ Report saved to $OUTPUT_FILE"
fi

Note: To implement output file support, the script structure should use:

bash

run_analysis() {
  # All echo statements from Phases 2-6 go here
  echo "=== THEME ANALYSIS ==="
  # ... rest of analysis phases
}

# Execute with optional tee
if [ -n "$OUTPUT_FILE" ]; then
  run_analysis | tee "$OUTPUT_FILE"
else
  run_analysis
fi

Integration with Meta-Learning Pipeline

This command integrates with:

•/clean-branch: Generates compound_learnings[] data after PR merges
•/meta-learn: Can reference compound analysis for context-aware suggestions
•/meta-improve: Weekly pipeline should include this command for PR retrospective insights
•/meta-implement: Apply high-priority compound suggestions

Example Usage

bash

# Analyze all compound learnings
/meta-compound-analyze

# Analyze only recent PRs
/meta-compound-analyze --since 30d

# Filter for high-confidence suggestions only
/meta-compound-analyze --min-confidence high

# Generate report file
/meta-compound-analyze --output roadmap.md

# Combine filters
/meta-compound-analyze --since 60d --min-confidence medium --output quarterly-review.md

name: meta-compound-analyze
Analysis complete. Use /meta-implement to apply high-priority suggestions.

Success Criteria

•✅ Reads compound_learnings[] from telemetry.json
•✅ Aggregates theme frequencies across PRs
•✅ Clusters similar suggestions by text similarity
•✅ Tracks quality metric trends (review iterations, fix commits, comments)
•✅ Generates prioritized improvement backlog using scoring formula
•✅ Outputs markdown report with tables and trend indicators
•✅ Supports filtering by time range and confidence level
•✅ Handles edge cases (no data, insufficient data for trends, missing jq)
•✅ Integrates with /meta-improve weekly pipeline

Notes

•jq dependency: Command degrades gracefully if jq not available
•Trend calculation: Requires 6+ PRs for meaningful trend analysis (compares first half vs second half)
•Priority scoring: (frequency × confidence_weight) where high=3, medium=2, low=1
•Clustering approach: Groups exact matches; semantic clustering would require AI analysis
•Privacy: Only uses PR numbers, never includes PR titles or code content
