🧠 Redundancy Patterns¶

Rollback Strategies¶

Feature Rollback (General):

# Revert feature implementation
git revert <feature_commit_range>

# Remove feature flag
sed -i '/ENABLE_FEATURE_X/d' config.py

# Restore previous version
./scripts/mcp/mcp-package --version 1.0 --legacy-mode

Scenario 1: Size Estimation Produces Inaccurate Results

# Rollback: Disable estimation flag
# Users can package normally without estimation

# Root cause investigation
# Check file size calculation accuracy
# Verify overhead percentage correct

# Fix and re-release in next iteration

Scenario 2: Exclude Patterns Break File Selection

# Rollback: Remove --exclude flag from CLI
# Affected users use manual filtering

# Fix: Review glob pattern matching logic
# Test edge cases (nested exclusions, wildcards)
# Re-release with comprehensive tests

Scenario 3: Interactive Mode Terminal Incompatibility

# Rollback: Mark interactive mode as experimental
# Provide terminal compatibility matrix

# Fallback: CLI-only mode remains available
# Fix: Test on additional terminals
# Add compatibility detection

Recovery Procedures¶

Data Integrity: - All features operate on copies (temp directories) - Source repository never modified - Package generation atomic (success or rollback)

State Recovery:

# Clean failed feature state
rm -rf /tmp/mcp_feature_*

# Reset to known good state
./scripts/mcp/mcp-package --reset-config

# Verify base functionality
./scripts/mcp/mcp-package --topic mcp --dry-run

User Migration:

# If breaking change introduced
# Provide migration script
./scripts/mcp/migrate_to_v2.sh

# Generate migration report
# Document all changes
# Offer legacy mode for transition period

Circuit Breakers¶

Performance Degradation: - If feature adds >20% overhead: Disable by default, opt-in flag - If feature causes timeout: Add progress indicators, increase limits - If memory usage spikes: Implement streaming/chunking

Compatibility Issues: - If <90% of users can use feature: Mark experimental - If breaks existing workflows: Immediate rollback - If requires new dependencies: Optional install path

Overview¶

This document outlines the roadmap for advanced features that will make the MCP Package System more powerful, flexible, and user-friendly. Each feature includes implementation details, dependencies, effort estimates, and success criteria.

Feature 1: Package Size Estimation¶

Description¶

Add --estimate flag to predict package size before creation, enabling users to adjust filters proactively.

Use Case¶

# Estimate before creating
./scripts/mcp/mcp-package --topic testing --estimate
# Output: Estimated size: 28.5 MB (1,645 files)
#         Warning: Approaching 50 MB limit

# Adjust and re-estimate
./scripts/mcp/mcp-package --custom "tests/agents/**" --estimate
# Output: Estimated size: 2.1 MB (145 files)

Implementation Details¶

File: scripts/mcp/mcp-package (enhance MCPPackager class)

def estimate_size(self, topic: str = None, custom: str = None) -> Dict[str, Any]:
    """Estimate package size without creating it"""
    # 1. Use select_components.py to get file list
    # 2. Sum file sizes with os.path.getsize()
    # 3. Add ~10% overhead for manifest, README, index
    # 4. Return dict with total_size_mb, file_count, warnings
    pass

def package(self, ..., estimate_only: bool = False):
    """Add estimate_only parameter"""
    if estimate_only:
        result = self.estimate_size(topic, custom)
        self.print_estimate(result)
        return 0
    # ... existing packaging logic

CLI Changes: - Add --estimate flag (alias: -e) - Display size breakdown by file type - Color-code warnings (green <30 MB, yellow 30-50 MB, red >50 MB)

Validation: - Test with small topics (mcp: ~0.1 MB) - Test with large topics (testing: ~28 MB) - Verify estimate within ±5% of actual

Effort: 2-3 iteration-days
Dependencies: None
Priority: High

Feature 2: Exclude Patterns Support¶

Description¶

Add --exclude parameter to filter out unwanted files from selection, complementing include patterns.

Use Case¶

# Package agents but exclude tests
./scripts/mcp/mcp-package --topic agents --exclude "tests/**,**/*_test.py"

# Package docs but exclude drafts
./scripts/mcp/mcp-package --topic docs --exclude "**/DRAFT_*,**/WIP_*"

# Multiple exclusions
./scripts/mcp/mcp-package --custom "src/**" --exclude "**/__pycache__/**,**/*.pyc,**/node_modules/**"

Implementation Details¶

File: scripts/mcp/select_components.py

def expand_globs(patterns: List[str], base_dir: Path,
                 exclude_patterns: List[str] = None) -> Set[Path]:
    """Add exclude_patterns parameter"""
    matched_files = set()

    # ... existing inclusion logic ...

    if exclude_patterns:
        excluded = set()
        for ex_pattern in exclude_patterns:
            for path in base_dir.glob(ex_pattern):
                if path.is_file():
                    excluded.add(path.relative_to(base_dir))

        matched_files = matched_files - excluded

    return matched_files

CLI Changes (mcp-package): - Add --exclude / -x parameter - Accept comma-separated patterns - Show excluded count in summary

Validation: - Test exclusion of test files - Test exclusion of cache directories - Test combined include + exclude - Verify exclusions don't break manifest generation

Effort: 2-3 iteration-days
Dependencies: None
Priority: High

Feature 3: Duplicate Flat Name Resolution¶

Description¶

Automatically detect and resolve duplicate flat names (e.g., src/foo.py and tests/foo.py → src__foo.py and tests__foo.py) by appending short hash suffix.

Use Case¶

# Before: Error on duplicate flat names
# After: Automatic resolution

# Package with duplicates
./scripts/mcp/mcp-package --custom "src/utils.py,tests/utils.py"

# Output:
#   src__utils.py (original)
#   tests__utils_a3f2.py (duplicate resolved with hash)

Implementation Details¶

File: scripts/mcp/package_flatten.sh

# Enhanced flatten_filename function
flatten_filename() {
    local path="$1"
    local base_name=$(echo "$path" | sed 's|/|__|g')

    # Check if name exists in tracking file
    if grep -q "^${base_name}$" "$WORK_DIR/.flat_names"; then
        # Compute short hash of full path
        local hash=$(echo "$path" | sha256sum | cut -c1-4)
        base_name="${base_name%.*}_${hash}.${base_name##*.}"
    fi

    # Track this name
    echo "$base_name" >> "$WORK_DIR/.flat_names"
    echo "$base_name"
}

Manifest Enhancement:

{
  "flat_name": "tests__utils_a3f2.py",
  "original_path": "tests/utils.py",
  "duplicate_resolved": true,
  "conflict_with": "src__utils.py",
  "resolution_method": "hash_suffix"
}

Validation: - Create test with known duplicates - Verify hash suffix appended - Verify manifest documents resolution - Test with multiple duplicates (3+ files same name)

Effort: 3-4 iteration-days
Dependencies: None
Priority: Medium

Feature 4: Package Diff Tool¶

Description¶

Compare two packages to see what changed (added, removed, modified files).

Use Case¶

# Compare two versions
./scripts/mcp/package_diff.py \
  package_agents_2025-12-01.zip \
  package_agents_2025-12-30.zip

# Output:
# Added: 5 files
#   + agents/new_orchestrator.py
#   + tests/agents/test_new_orchestrator.py
# Removed: 2 files
#   - agents/deprecated_module.py
# Modified: 8 files
#   ≠ agents/workflow_navigator.py (SHA256 changed)

        return json.loads(manifest_data)

def diff_packages(pkg1_path: str, pkg2_path: str) -> Dict:
    """Compare two package manifests"""
    m1 = load_manifest(pkg1_path)
    m2 = load_manifest(pkg2_path)

    files1 = {f['original_path']: f for f in m1['files']}
    files2 = {f['original_path']: f for f in m2['files']}

    added = set(files2.keys()) - set(files1.keys())
    removed = set(files1.keys()) - set(files2.keys())
    common = set(files1.keys()) & set(files2.keys())

    modified = []
    for path in common:
        if files1[path]['sha256'] != files2[path]['sha256']:
            modified.append(path)

    return {
        'added': sorted(added),
        'removed': sorted(removed),
        'modified': sorted(modified),
        'unchanged': len(common) - len(modified)
    }

def print_diff(diff: Dict, verbose: bool = False):
    """Print formatted diff"""
    # Color-coded output with stats
    pass

if __name__ == '__main__':
    # CLI argument parsing
    # Run diff and display results
    pass

CLI:

package_diff.py <package1.zip> <package2.zip> [--verbose] [--json]

Output Formats: - Human-readable (default) - JSON (--json flag) - Detailed (--verbose with SHA256 and size changes)

Validation: - Test with identical packages (0 changes) - Test with one file added - Test with one file modified (different content) - Test with one file removed

Effort: 3-4 iteration-days
Dependencies: None
Priority: Medium

Feature 5: Package Merge Tool¶

Description¶

Combine multiple packages into one, resolving conflicts intelligently.

Use Case¶

# Merge agent and testing packages
./scripts/mcp/package_merge.py \
  agents_package.zip \
  testing_package.zip \
  --output combined_agents_testing.zip \
  --conflict-strategy newest

# Conflict strategies:
#   newest: Keep file with latest timestamp
#   largest: Keep larger file
#   manual: Prompt for each conflict
#   rename: Keep both with suffixes

Implementation Details¶

File: scripts/mcp/package_merge.py

#!/usr/bin/env python3
from typing import List, Dict

    for pkg_path in package_paths:
        manifest = load_manifest(pkg_path)

        for file_info in manifest['files']:
            orig_path = file_info['original_path']

            if orig_path in merged_files:
                # Conflict! Apply strategy
                merged_files[orig_path] = resolve_conflict(
                    merged_files[orig_path],
                    file_info,
                    conflict_strategy
                )
            else:
                merged_files[orig_path] = file_info

    return merged_files

def resolve_conflict(existing: Dict, new: Dict, strategy: str) -> Dict:
    """Apply conflict resolution strategy"""
    if strategy == 'newest':
        # Compare generated_at or file modification time
        pass
    elif strategy == 'largest':
        return existing if existing['size_bytes'] > new['size_bytes'] else new
    elif strategy == 'manual':
        # Interactive prompt
        pass
    elif strategy == 'rename':
        # Keep both with _v1, _v2 suffixes
        pass
