IRON LAW: User Specifications Are Sacred

THIS LAW IS ABSOLUTE AND ADMITS NO EXCEPTIONS.

1. Every word the user says is a specification - follow verbatim, no errors, no exceptions
2. Never modify user specs without explicit discussion - if you identify a potential issue, STOP and discuss with the user FIRST
3. Never take initiative to change specifications - your role is to implement, not to reinterpret
4. If you see an error in the spec, you MUST:
   • Stop immediately
   • Explain the potential issue clearly
   • Wait for user guidance before proceeding
5. No silent "improvements" - what seems like an improvement to you may break the user's intent

Violation of this law invalidates all work produced.

Background Agent Boundaries

When running as a background agent, you may ONLY write to:

• The project directory and its subdirectories
• The parent directory (for sub-git projects)
• ~/.claude (for plugin/settings fixes)
• /tmp

Do NOT write outside these locations.

GHE_REPORTS Rule (MANDATORY)

ALL reports MUST be posted to BOTH locations:

1. GitHub Issue Thread - Full report text (NOT just a link!)
2. GHE_REPORTS/ - Same full report text (FLAT structure, no subfolders!)

Report naming: <TIMESTAMP>_<title or description>_(<AGENT>).md Timestamp format: YYYYMMDDHHMMSSTimezone

ALL 11 agents write here: Athena, Hephaestus, Artemis, Hera, Themis, Mnemosyne, Hermes, Ares, Chronos, Argos Panoptes, Cerberus

REQUIREMENTS/ is SEPARATE - permanent design documents, never deleted.

Deletion Policy: DELETE ONLY when user EXPLICITLY orders deletion due to space constraints.

GHE Changelog Management

Overview

GHE maintains a comprehensive CHANGELOG that tracks:

1. Product Changes - Code, features, bug fixes
2. Design Changes - Architecture, patterns, decisions
3. Requirements Changes - REQ file updates, new requirements

CHANGELOG Structure

Automated Changelog Generation

Using git-diff to Detect Changes

#!/bin/bash
# Generate changelog entries from recent commits

# Get commits since last tag
LAST_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "")
if [ -z "$LAST_TAG" ]; then
  COMMITS=$(git log --oneline)
else
  COMMITS=$(git log --oneline ${LAST_TAG}..HEAD)
fi

# Categorize changes
ADDED=""
CHANGED=""
FIXED=""
REQUIREMENTS=""
DESIGN=""

while read -r commit; do
  HASH=$(echo "$commit" | cut -d' ' -f1)
  MSG=$(echo "$commit" | cut -d' ' -f2-)

  # Get files changed
  FILES=$(git diff-tree --no-commit-id --name-only -r "$HASH")

  # Categorize by commit message and files
  if echo "$MSG" | grep -qiE "^(add|feat|new):"; then
    ADDED="$ADDED\n- $MSG"
  elif echo "$MSG" | grep -qiE "^(fix|bug|patch):"; then
    FIXED="$FIXED\n- $MSG"
  elif echo "$MSG" | grep -qiE "^(change|update|refactor):"; then
    CHANGED="$CHANGED\n- $MSG"

    DESIGN="$DESIGN\n- $MSG"
  else

Detailed Diff Analysis

# Get detailed changes for a specific file type
analyze_changes() {
  local PATTERN=$1
  local SINCE=$2

  git diff "$SINCE" --stat -- "$PATTERN" | while read line; do
    FILE=$(echo "$line" | awk '{print $1}')
    INSERTIONS=$(echo "$line" | grep -oP '\d+(?= insertion)')
    DELETIONS=$(echo "$line" | grep -oP '\d+(?= deletion)')

    echo "- \`$FILE\`: +$INSERTIONS/-$DELETIONS lines"
  done
}

# Example usage
echo "### Code Changes"
analyze_changes "src/**/*.py" "$LAST_TAG"

echo "### Requirements Changes"
analyze_changes "REQUIREMENTS/**/*.md" "$LAST_TAG"

Requirements Changelog Section

Track all REQ file changes:

# Generate requirements changelog
generate_req_changelog() {
  local SINCE=$1

  echo "### Requirements"
  echo ""

  # New requirements
  NEW_REQS=$(git diff "$SINCE" --diff-filter=A --name-only -- "REQUIREMENTS/*.md")
  if [ -n "$NEW_REQS" ]; then
    echo "#### New Requirements"
    for req in $NEW_REQS; do
      REQ_ID=$(grep "^req_id:" "$req" | cut -d' ' -f2)
      TITLE=$(grep "^# REQ-" "$req" | sed 's/^# //')
      echo "- **$REQ_ID**: $TITLE"
    done
    echo ""
  fi

  # Modified requirements
  MOD_REQS=$(git diff "$SINCE" --diff-filter=M --name-only -- "REQUIREMENTS/*.md")
  if [ -n "$MOD_REQS" ]; then
    echo "#### Updated Requirements"
    for req in $MOD_REQS; do
      REQ_ID=$(grep "^req_id:" "$req" | cut -d' ' -f2)
      OLD_VER=$(git show "$SINCE:$req" 2>/dev/null | grep "^version:" | cut -d' ' -f2)
      NEW_VER=$(grep "^version:" "$req" | cut -d' ' -f2)
      echo "- **$REQ_ID**: v$OLD_VER -> v$NEW_VER"
    done
    echo ""
  fi

  # Deprecated requirements
  DEP_REQS=$(git diff "$SINCE" --name-only -- "REQUIREMENTS/*.md" | while read req; do
    if grep -q "status: deprecated" "$req" 2>/dev/null; then
      echo "$req"
    fi
  done)
  if [ -n "$DEP_REQS" ]; then
    echo "#### Deprecated Requirements"
    for req in $DEP_REQS; do
      REQ_ID=$(grep "^req_id:" "$req" | cut -d' ' -f2)
      echo "- **$REQ_ID** (deprecated)"
    done
  fi
}

Design Decision Tracking

Track architecture and design changes:

### Design Decisions

#### [DD-001] Decision Title
- **Date**: YYYY-MM-DD
- **Status**: Accepted | Superseded | Deprecated
- **Context**: Why was this decision needed?
- **Decision**: What was decided?
- **Consequences**: What are the implications?
- **Related**: REQ-XXX, Issue #N

Automated Design Detection

# Detect design-impacting changes
detect_design_changes() {
  local SINCE=$1

  # Architecture files
  ARCH_CHANGES=$(git diff "$SINCE" --name-only -- \
    "docs/architecture*.md" \
    "docs/design*.md" \
    "DESIGN*.md" \
    "ADR/*.md" \
    "**/README.md")

  # Major structural changes (new directories, renamed files)
  STRUCT_CHANGES=$(git diff "$SINCE" --summary | grep -E "^(create|rename|delete) mode")

  # Interface changes
  INTERFACE_CHANGES=$(git diff "$SINCE" -- "**/*.py" | grep -E "^[\+\-].*def __init__|^[\+\-].*class |^[\+\-].*@abstractmethod")

  if [ -n "$ARCH_CHANGES" ] || [ -n "$STRUCT_CHANGES" ] || [ -n "$INTERFACE_CHANGES" ]; then
    echo "### Design Changes Detected"
    echo ""
    echo "Review the following for design documentation updates:"
    echo ""
    [ -n "$ARCH_CHANGES" ] && echo "**Architecture docs modified**:" && echo "$ARCH_CHANGES" | sed 's/^/- /'
    [ -n "$STRUCT_CHANGES" ] && echo "**Structural changes**:" && echo "$STRUCT_CHANGES" | sed 's/^/- /'
    [ -n "$INTERFACE_CHANGES" ] && echo "**Interface changes detected** (review for breaking changes)"
  fi
}

Integration with GHE Workflow

After Each Phase Completion

# Post phase completion, update changelog
update_changelog_for_phase() {
  local PHASE=$1
  local ISSUE=$2

  ISSUE_TITLE=$(gh issue view "$ISSUE" --json title --jq '.title')

  case $PHASE in
    "dev")
      echo "- [$ISSUE_TITLE](#$ISSUE) - Development complete" >> CHANGELOG.md
      ;;
    "test")
      echo "- [$ISSUE_TITLE](#$ISSUE) - Tests passing" >> CHANGELOG.md
      ;;
    "review")
      echo "- [$ISSUE_TITLE](#$ISSUE) - Reviewed and approved" >> CHANGELOG.md
      ;;
  esac
}

On Release

# Prepare release changelog
prepare_release() {
  local VERSION=$1
  local DATE=$(date +%Y-%m-%d)

  # Move unreleased to new version
  sed -i "s/## \[Unreleased\]/## [$VERSION] - $DATE\n\n## [Unreleased]/" CHANGELOG.md

  # Commit
  git add CHANGELOG.md
  git commit -m "Release $VERSION changelog"
  git tag "v$VERSION"
}

Settings Awareness

Respects .claude/ghe.local.md:

changelog_file: CHANGELOG.md      # Changelog location
track_requirements: true          # Include REQ changes
track_design: true               # Include design changes
auto_update: true                # Update on phase completion

Best Practices

1. Commit Messages Matter - Use conventional commits (feat:, fix:, etc.)
2. Version Requirements - Always version REQ files when changing
3. Document Design Decisions - Create ADRs for major changes
4. Review Before Release - Always review auto-generated entries
5. Link Everything - Reference issues, PRs, and requirements
