🚀 DevStream Task Handoff: GitHub Repository Cleanup and Release 0.2.0

FROM: Claude Sonnet 4.5 (Strategic Planning Complete) TO: GLM-4.6 (Implementation Execution)

📊 TASK CONTEXT

Task ID: a708b697-6291-40cd-af06-d3fb9ec8569f Phase: repository-synchronization Priority: 8/10 Status: Steps 1-4 COMPLETED by Sonnet 4.5 → Steps 5-7 DELEGATED to you

Your Role: You are an expert execution-focused coding agent. Sonnet 4.5 has completed all strategic planning. Your job is precise implementation according to the approved plan.

✅ WORK COMPLETED (Steps 1-4)

✅ DISCUSSION: Repository cleanup scope defined, trade-offs identified
✅ ANALYSIS: GitHub repository state analyzed, violations identified, PR status checked
✅ RESEARCH: Context7 findings documented (git-filter-repo, GitHub CLI, semantic-release)
✅ PLANNING: Detailed 6-task implementation plan created (see linked file)
✅ APPROVAL: Plan approved, ready for execution

📋 YOUR IMPLEMENTATION PLAN

COMPLETE PLAN: docs/development/plan/piano_github_cleanup_360.md READ THE PLAN FIRST using:

cat docs/development/plan/piano_github_cleanup_360.md

Plan Summary (excerpt): The plan consists of 6 micro-tasks covering repository cleanup, PR management, changelog generation, and release creation. Each task has specific Context7 patterns, exact function signatures, and 95%+ test coverage requirements. Total estimated duration: 4 hours.

🎯 YOUR MISSION (Steps 5-7)

Step 5: APPROVAL

Review the complete implementation plan
Confirm understanding of all requirements
NEVER proceed without explicit user authorization

Step 6: IMPLEMENTATION

Execute micro-tasks one at a time
Follow plan specifications exactly
Use TodoWrite: mark "in_progress" → work → "completed"
Run tests after each micro-task
NEVER mark completed with failing tests

Step 7: VERIFICATION

95%+ test coverage for all new code
mypy --strict zero errors
Repository health validation
@code-reviewer validation (automatic on commit)

🔧 DEVSTREAM PROTOCOL COMPLIANCE (MANDATORY)

CRITICAL RULES (from @CLAUDE.md):

Python Environment

# ALWAYS use .devstream venv
.devstream/bin/python script.py       # ✅ CORRECT
.devstream/bin/python -m pytest       # ✅ CORRECT
python script.py                       # ❌ FORBIDDEN

TodoWrite Workflow

Mark first task "in_progress"
Implement according to plan
Run tests
Mark "completed" ONLY when:
- Tests pass 100%
- Type check passes
- Acceptance criteria met
Proceed to next task

Context7 Usage

# When you encounter unknowns
library_id = mcp__context7__resolve-library-id(libraryName="git-filter-repo")
docs = mcp__context7__get-library-docs(
    context7CompatibleLibraryID=library_id,
    topic="repository history cleanup invert-paths",
    tokens=2000
)

Memory Search

# Before implementing, search for existing patterns
mcp__devstream__devstream_search_memory(
    query="git repository cleanup .gitignore violations",
    content_type="code",
    limit=5
)

📚 CONTEXT7 RESEARCH (Pre-Completed by Sonnet)

GitHub CLI Integration

Libraries Researched:

GitHub CLI (Trust Score: 8.2/10) - Pull request management and release creation
git-filter-repo (Trust Score: 8.7/10) - Repository history cleanup with invert-paths
semantic-release (Trust Score: 8.7/10) - Changelog generation from conventional commits

Key Findings:

GitHub CLI: Use gh pr merge, gh pr close, gh release create for automation
git-filter-repo: Use --path <directory> --invert-paths for directory removal
Repository Cleanup: Always use git reflog expire --expire=now --all and git gc --prune=now after history changes

Pattern Examples:

# Remove directories from history
git filter-repo --path mcp-devstream-server/ --invert-paths

# Create GitHub release
gh release create v0.2.0 --title "DevStream v0.2.0" --notes-file CHANGELOG.md

# Cleanup repository after changes
git reflog expire --expire=now --all
git gc --prune=now

When to use: Repository cleanup operations that require history rewriting or release management

🏗️ TECHNICAL SPECIFICATIONS

Files to Modify:

.gitignore - Update with missing patterns
CHANGELOG.md - Create comprehensive changelog for v0.2.0
tests/unit/test_github_cleanup.py - Create comprehensive test suite

Files to Remove:

.DS_Store files (multiple locations)
.coverage (root directory)
*.log files in various locations
*.bak files (.env.devstream.bak, etc.)
mcp-devstream-server/ directory
node_modules/ directory
.archive/ directory

Dependencies (already in requirements.txt):

pytest (testing)
mypy (type checking)
structlog (logging)
GitHub CLI (gh) - external tool

Critical Commands:

# Backup before history changes
git clone origin backup-$(date +%Y%m%d-%H%M%S)

# git-filter-repo operations
git filter-repo --path <directory> --invert-paths

# Cleanup after changes
git reflog expire --expire=now --all
git gc --prune=now

# GitHub operations
gh pr merge 10 --merge
gh release create v0.2.0 --title "DevStream v0.2.0" --notes-file CHANGELOG.md

🚨 CRITICAL CONSTRAINTS (DO NOT VIOLATE)

FORBIDDEN ACTIONS:

❌ NO repository history changes without backup
❌ NO force push without verification
❌ NO removal of files without .gitignore update
❌ NO skipping TodoWrite workflow
❌ NO early quit on complex tasks

REQUIRED ACTIONS:

✅ YES use .devstream/bin/python for ALL commands
✅ YES follow TodoWrite plan strictly
✅ YES use Context7 for git operations
✅ YES create repository backup before history changes
✅ YES maintain ALL existing functionality
✅ YES full type hints + docstrings EVERY function
✅ YES tests for EVERY feature (95%+ coverage)

✅ QUALITY GATES (Check Before Completion)

1. Environment Verification

# Verify venv and Python version
.devstream/bin/python --version  # Must be 3.11.x
.devstream/bin/python -m pip list | grep -E "(pytest|mypy|structlog)"

2. Repository Backup

# Create backup before history changes
git clone origin backup-$(date +%Y%m%d-%H%M%S)

3. Implementation

Follow plan in docs/development/plan/piano_github_cleanup_360.md

4. Testing

# After EVERY micro-task
.devstream/bin/python -m pytest tests/unit/test_github_cleanup.py -v
.devstream/bin/python -m mypy tests/unit/test_github_cleanup.py --strict

# Before completion (ALL tests)
.devstream/bin/python -m pytest tests/unit/test_github_cleanup.py -v \
    --cov=tests/unit/test_github_cleanup.py \
    --cov-report=term-missing \
    --cov-report=html

# REQUIREMENT: ≥95% coverage, 100% pass rate

5. Commit (if all tests pass)

git add .
git commit -m "$(cat <<'EOF'
