Project Progress Tracker

Project: Codebase Onboarding System

Started: December 29, 2025 Status: ✅ Complete


Completed Items

Phase 1: Core Plugin Structure ✅

  • plugin.json - Claude Code plugin manifest
  • README.md - User documentation with installation, usage, examples
  • .gitignore - Git ignore file
  • Directory structure setup

Phase 2: Codebase Explorer Skill ✅

  • skills/codebase-explorer/SKILL.md - Skill documentation
  • scripts/analyze-structure.sh - High-level structure analysis
  • scripts/find-entrypoints.sh - Entry point detection
  • scripts/dep-graph.sh - Dependency graph analysis
  • scripts/hot-files.sh - Technical debt hotspots
  • scripts/find-god-classes.sh - Oversized class detection
  • scripts/find-circular-deps.sh - Circular dependency detection
  • scripts/map-vertical-slice.sh - Vertical slice tracing
  • scripts/find-seams.sh - Module boundary identification

Phase 3: Onboarding System Skill ✅

  • skills/onboarding-system/SKILL.md - Six-phase methodology
  • templates/progress.yml - Onboarding progress tracking
  • templates/setup-notes.md - Environment setup notes
  • templates/overview.md - System overview template
  • templates/domain-glossary.md - Domain terminology
  • templates/module-notes.md - Module exploration notes
  • templates/cross-cutting.md - Cross-cutting concerns
  • templates/journal.md - Daily learning journal

Phase 4: Agents ✅

  • agents/onboarding-orchestrator.md - Opus model, drives 6-phase process
  • agents/codebase-cartographer.md - Sonnet model, high-level mapping
  • agents/module-archaeologist.md - Sonnet model, deep-dive exploration

Phase 5: Commands ✅

  • commands/onboard.md - Start/resume onboarding
  • commands/explore.md - Quick exploration
  • commands/dive.md - Deep-dive into modules

Phase 6: Cross-Platform ✅

  • scripts/build-copilot.sh - GitHub Copilot compatibility builder

Phase 7: Testing ✅

  • Test scripts on sample Java project
  • Verify build-copilot.sh generates correct output
  • All 8 analysis scripts verified working

Notes

Script Testing Results (on /tmp/sample-java-project)

  • analyze-structure.sh: ✅ Working - Detected Maven, Spring Boot, packages, LOC
  • find-entrypoints.sh: ✅ Working - Found main class, controllers, Kafka listeners
  • dep-graph.sh: ✅ Working - Analyzed dependencies and package relationships
  • map-vertical-slice.sh: ✅ Working - Traced user controller through all layers
  • hot-files.sh: ✅ Working (after fix) - Detects TODOs, FIXMEs, complex files
  • find-god-classes.sh: ✅ Working (after fix) - Detects oversized classes
  • find-circular-deps.sh: ✅ Working - Layer violation and cycle detection
  • find-seams.sh: ✅ Working - Module boundary identification

Build Script Testing

  • build-copilot.sh: ✅ Working - Successfully generates dist/copilot/.github/ structure
  • Verified transformations: Claude Code → GitHub Copilot format
  • Agent tool conversion: Agent → Multi-turn, Bash → shell
  • Handoff instructions properly added

Issues Found & Resolved

Issue 1: hot-files.sh integer comparison error

Problem: Script failed with [: : integer expression expected when grep returned empty Solution: Added null checks before integer comparisons

if [ -n "$TODOS" ] && [ "$TODOS" -gt 0 ]; then

Issue 2: find-god-classes.sh integer comparison error

Problem: Script failed with [: 0 0: integer expression expected due to grep output issues Solution: Rewrote script with more robust parsing:

  • Added | head -1 after grep -c to ensure single value
  • Added | tr -d ' ' to remove whitespace
  • Added || echo 0 fallbacks with ${VAR:-0} defaults
  • Wrapped comparisons in 2>/dev/null safety

Issue 3: find-seams.sh exit code 1

Problem: Script exited with code 1 due to set -e and grep returning no matches Solution: Removed set -e since many grep commands legitimately return empty results
