CODITECT-STANDARD-SCRIPTS.md

Version: 1.0.0 Status: ✅ Approved Last Updated: December 3, 2025 Authority: Based on 92 production scripts (48,798 lines) in CODITECT framework Compliance Target: Grade B (80%) minimum for all new scripts

Executive Summary

This standard defines requirements for all utility and automation scripts in the CODITECT framework. Scripts are executable automation tools that provide CLI interfaces for framework operations including project lifecycle management, git automation, session management, and intelligent task execution.

Key Requirements:

Python scripts use #!/usr/bin/env python3 shebang
Shell scripts use #!/bin/bash with set -e
All scripts executable (chmod +x)
Comprehensive CLI argument parsing (argparse for Python, getopts for Bash)
Security-first design (input validation, injection prevention)
Integration with skills as Level 3 resources
Structured logging and progress reporting

Target Audience: Developers creating automation scripts for CODITECT framework operations.

Framework Context: CODITECT scripts discovered in skills via progressive disclosure pattern, referenced as Level 3 resources, and executed via Bash tool or direct CLI invocation. Scripts are the executable layer of the CODITECT automation stack.

Directory Rules:

Root level: Project-level operations (setup, git, checkpoints, analysis)
scripts/core/: Framework core utilities (agent dispatch, session management, database)
scripts/workflows/: Complex multi-step workflow orchestration
scripts/generated/: Auto-generated scripts (do not edit manually)
scripts/generated_tasks/: Task-specific execution scripts
scripts/llm_execution/: LLM API adapters and execution wrappers

Naming Conventions

File Names:

Use kebab-case with descriptive names
Extension indicates language: .py (Python), .sh (Bash)
Examples:
- ✅ session-index-generator.py
- ✅ git-workflow.py
- ✅ init.sh
- ✅ update-component-activation.py
- ❌ sessionIndexGenerator.py (camelCase not allowed)
- ❌ script1.py (non-descriptive)

Naming Pattern:

[verb]-[noun]-[modifier].[ext]

Examples:

create-checkpoint.py - Creates checkpoints
session-index-generator.py - Generates session index
export-dedup.py - Exports with deduplication
git-workflow.py - Git workflow automation
init.sh - Initialization script

Function/Method Names (Python):

Use snake_case following PEP 8
Descriptive verbs for actions
Examples: parse_arguments(), validate_input(), update_watermark()

Function Names (Bash):

Use snake_case
Examples: parse_args(), validate_path(), check_dependencies()

File Format Requirements

Python Scripts (.py):

UTF-8 encoding
Unix line endings (LF)
PEP 8 compliant
Type hints for function signatures (Python 3.10+)
Docstrings for modules, classes, and functions (Google style)

Shell Scripts (.sh):

UTF-8 encoding
Unix line endings (LF)
ShellCheck compliant (if available)
POSIX compatible or explicitly Bash-specific
Comment blocks for functions

File Size Guidance:

Small utility scripts: 100-300 lines
Standard scripts: 300-500 lines
Complex scripts: 500+ lines
If >1000 lines, consider splitting into modules

Shebang Requirements

Python Scripts:

#!/usr/bin/env python3

Why: Portable across systems, uses python3 from PATH.

Shell Scripts:

#!/bin/bash

Why: Explicit Bash requirement (not POSIX sh), enables Bash-specific features.

Verification:

# Check shebang
head -1 script.py
# Should output: #!/usr/bin/env python3

head -1 script.sh
# Should output: #!/bin/bash

Permissions

All scripts must be executable:

chmod +x script.py
chmod +x script.sh

Verification:

ls -l script.py
# Should show: -rwxr-xr-x ... script.py

Git Tracking: Git tracks executable permissions. Verify with:

git ls-files -s script.py
# 100755 indicates executable

        default=100,
        help="Limit number of results (default: 100)"
    )

    return parser.parse_args()

Bash: getopts Pattern

OUTPUT_FILE="output.txt"
VERBOSE=false
DRY_RUN=false

while [[ $# -gt 0 ]]; do
    case $1 in
        -h|--help)

Integration with Skills

Scripts are Level 3 resources in skills, invoked via Bash tool:

Skill Reference Pattern

---
name: session-analysis
description: Analyze Claude Code sessions for patterns and progress
version: 1.0.0
---

# Session Analysis Skill

## Level 1: Quick Overview
Analyze session history and extract development patterns.

## Level 2: Usage Instructions
Execute session analysis script to generate reports.

## Level 3: Implementation Resources

### Script: session-index-generator.py

**Location:** `.coditect/scripts/session-index-generator.py`

**Purpose:** Generate comprehensive index of Claude Code sessions

**Usage:**
```bash
python3 .coditect/scripts/session-index-generator.py [options]

Options:

-o, --output PATH - Output file path (default: ./CLAUDE-SESSION-INDEX.md)
-j, --json - Also output JSON format
-p, --project PATTERN - Filter to projects matching pattern
-v, --verbose - Verbose output

Examples:

# Generate index for all sessions
python3 .coditect/scripts/session-index-generator.py

# Filter to specific project
python3 .coditect/scripts/session-index-generator.py -p "coditect-core"

# Output JSON format
python3 .coditect/scripts/session-index-generator.py --json

Output: Markdown index with clickable file:// links and session metadata.

### AI Agent Invocation Pattern

```python
# AI agent invoking script via Bash tool
Bash(
    command="python3 .coditect/scripts/session-index-generator.py --json --output session-index.json",
    description="Generate session index with JSON output"
)

Script Discovery by AI Agents

Scripts should be discoverable via Grep/Glob:

# Find scripts related to session analysis
Grep(pattern="session.*analy", glob="scripts/*.py", output_mode="files_with_matches")

# Find all Python scripts
Glob(pattern="scripts/**/*.py")

Security Best Practices

Input Validation

Always validate input:

# Python: Validate file paths
def validate_path(path: Path, must_exist: bool = True) -> bool:
    """Validate file path for security."""
    # Convert to absolute path
    path = path.resolve()

    # Check for path traversal attempts
    if ".." in str(path):
        logger.error("Path traversal attempt detected")
        return False

    # Check existence
    if must_exist and not path.exists():
        logger.error(f"Path does not exist: {path}")
        return False

    return True

# Python: Validate JSON input
def validate_json_schema(data: Dict[str, Any], schema: Dict[str, Any]) -> bool:
    """Validate JSON against schema."""
    import jsonschema
    try:
        jsonschema.validate(instance=data, schema=schema)
        return True
    except jsonschema.ValidationError as e:
        logger.error(f"JSON validation failed: {e}")
        return False

# Bash: Validate file paths
validate_path() {
    local path="$1"

    # Check for path traversal
    if [[ "$path" == *".."* ]]; then
        error "Path traversal attempt detected: $path"
    fi

    # Check existence
    if [ ! -e "$path" ]; then
        error "Path does not exist: $path"
    fi

    # Check readability
    if [ ! -r "$path" ]; then
        error "Path not readable: $path"
    fi

    return 0
}

Command Injection Prevention

Sanitize inputs before using in shell commands:

# Python: Use subprocess with list arguments (NOT shell=True)
import subprocess

# ✅ GOOD: List arguments (no shell injection)
result = subprocess.run(
    ["git", "log", "--oneline", "-5"],
    capture_output=True,
    text=True,
    check=True
)

# ❌ BAD: Shell command with user input (vulnerable to injection)
user_input = "main; rm -rf /"
result = subprocess.run(
    f"git log {user_input}",
    shell=True,  # NEVER use shell=True with user input
    capture_output=True,
    text=True
)

# Bash: Quote all variables
# ✅ GOOD: Quoted variable
git log --oneline "$USER_INPUT"

# ❌ BAD: Unquoted variable (vulnerable to word splitting and injection)
git log --oneline $USER_INPUT

Dependency Checking

Check dependencies before use:

# Python: Check for required imports
import shutil

def check_dependencies() -> bool:
    """Check for required system dependencies."""
    required = ["git", "jq"]

    for cmd in required:
        if not shutil.which(cmd):
            logger.error(f"Required command not found: {cmd}")
            return False

    return True

# Bash: Check for required commands
check_dependencies() {
    local deps=("git" "jq" "python3")

    for dep in "${deps[@]}"; do
        if ! command -v "$dep" &> /dev/null; then
            error "Required dependency not found: $dep"
        fi
    done

    return 0
}

Secure Temporary Files

# Python: Use tempfile module
import tempfile
from pathlib import Path

# Create secure temporary file
with tempfile.NamedTemporaryFile(mode='w', delete=False, suffix='.json') as f:
    json.dump(data, f)
    temp_path = Path(f.name)

try:
    # Use temp file
    process_file(temp_path)
finally:
    # Clean up
    temp_path.unlink()

# Bash: Use mktemp
TEMP_FILE=$(mktemp)
trap "rm -f $TEMP_FILE" EXIT

# Use temp file
echo "data" > "$TEMP_FILE"
process_file "$TEMP_FILE"

Error Handling Patterns

Python: Try-Except with Specific Exceptions

def main() -> int:
    """Main execution with comprehensive error handling."""
    try:
        # Main logic
        result = process_data()
        return 0

    except FileNotFoundError as e:
        logger.error(f"File not found: {e}")

Bash: Error Trapping

#!/bin/bash

Atomic File Operations

Prevent corruption from partial writes:

# Python: Atomic write with temporary file + rename
import tempfile
import shutil
from pathlib import Path

def atomic_write(path: Path, content: str) -> None:
    """Write file atomically to prevent corruption."""
    temp = Path(tempfile.mktemp(dir=path.parent, suffix='.tmp'))

    try:
        # Write to temp file
        temp.write_text(content, encoding='utf-8')

        # Atomic rename
        temp.rename(path)

    except Exception:
        # Cleanup on failure
        if temp.exists():
            temp.unlink()
        raise

# Bash: Atomic write with temporary file + mv
atomic_write() {
    local target_file="$1"
    local content="$2"

    local temp_file="${target_file}.tmp"

    # Write to temp file
    echo "$content" > "$temp_file"

    # Atomic move
    mv "$temp_file" "$target_file"
}

Logging and Progress Reporting

Python: Structured Logging

import logging
from datetime import datetime

# Setup logging with custom format
logging.basicConfig(
    level=logging.INFO,
    format="%(asctime)s - %(name)s - %(levelname)s - %(message)s",
    datefmt="%Y-%m-%d %H:%M:%S"
)
logger = logging.getLogger(__name__)

# Log levels
logger.debug("Detailed debug information")
logger.info("General informational message")
logger.warning("Warning: something unexpected")
logger.error("Error: operation failed")
logger.critical("Critical: system failure")

# Progress reporting
def process_items(items: List[Any]) -> None:
    total = len(items)
    for i, item in enumerate(items, 1):
        logger.info(f"Processing item {i}/{total} ({i*100//total}%)")
        process_item(item)

Bash: Color-Coded Output

# Color definitions
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[1;33m'
BLUE='\033[0;34m'
NC='\033[0m' # No Color

# Output functions
error() {
    echo -e "${RED}Error: $1${NC}" >&2
}

warn() {
    echo -e "${YELLOW}Warning: $1${NC}" >&2
}

info() {
    echo -e "${GREEN}$1${NC}"
}

debug() {
    if [ "$VERBOSE" = true ]; then
        echo -e "${BLUE}Debug: $1${NC}" >&2
    fi
}

# Progress reporting
process_items() {
    local items=("$@")
    local total=${#items[@]}
    local i=1

    for item in "${items[@]}"; do
        info "Processing item $i/$total ($(( i * 100 / total ))%)"
        process_item "$item"
        ((i++))
    done
}

JSON Output for Programmatic Use

# Python: Structured JSON output
import json
from typing import Dict, Any

def output_json(data: Dict[str, Any], file_path: Optional[Path] = None) -> None:
    """Output structured JSON for programmatic use."""
    json_str = json.dumps(data, indent=2, ensure_ascii=False)

    if file_path:
        file_path.write_text(json_str, encoding='utf-8')
    else:
        print(json_str)

# Example usage
result = {
    "status": "success",
    "timestamp": datetime.utcnow().isoformat() + "Z",
    "processed": 42,
    "errors": []
}
output_json(result, Path("output.json"))

# Bash: JSON output with jq
output_json() {
    local status="$1"
    local message="$2"

    jq -n \
        --arg status "$status" \
        --arg message "$message" \
        --arg timestamp "$(date -u +%Y-%m-%dT%H:%M:%SZ)" \
        '{
            status: $status,
            message: $message,
            timestamp: $timestamp
        }'
}

# Usage
output_json "success" "Processing complete" > output.json

# - Error handling patterns

Migration Guide

Upgrading Existing Scripts to Standard

Phase 1: Basic Compliance (Grade C → B)

Add/Fix Shebang:

#!/usr/bin/env python3  # Add if missing

Make Executable:

chmod +x script.py
git add --chmod=+x script.py

Add Docstring:

"""
Script description.

Usage: python3 script.py [options]
"""

Add argparse:

import argparse

def parse_arguments():
    parser = argparse.ArgumentParser(description="Script description")
    parser.add_argument("-h", "--help", action="help")
    parser.add_argument("-v", "--verbose", action="store_true")
    return parser.parse_args()

Add Logging:

import logging

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

Phase 2: Production-Ready (Grade B → A)

Add Type Hints (Python):

from typing import Dict, List, Optional

def process_data(data: Dict[str, Any]) -> List[str]:
    ...

Add Security Validation:

def validate_path(path: Path) -> bool:
    path = path.resolve()
    if ".." in str(path):
        logger.error("Path traversal detected")
        return False
    return True

Add Progress Reporting:

for i, item in enumerate(items, 1):
    logger.info(f"Processing {i}/{len(items)}")

Add JSON Output:

parser.add_argument("-j", "--json", action="store_true")
if args.json:
    print(json.dumps(result, indent=2))

Document in Skill: Update corresponding skill to reference script as Level 3 resource.

Troubleshooting

Common Issues

Issue: Script Not Executable

Symptom:

$ ./script.py
bash: ./script.py: Permission denied

Solution:

chmod +x script.py
git add --chmod=+x script.py

Issue: Wrong Python Version

Symptom:

$ python script.py
SyntaxError: invalid syntax (type hints not supported)

Solution: Use python3 explicitly:

python3 script.py

Or fix shebang and make executable:

#!/usr/bin/env python3
chmod +x script.py
./script.py

Issue: Module Not Found

Symptom:

ModuleNotFoundError: No module named 'requests'

Solution:

Check dependencies documented
Install missing module:
```
pip3 install requests
```
Add to requirements.txt if project-wide

Issue: Command Injection Vulnerability

Symptom:

# Vulnerable code
os.system(f"git log {user_input}")

Solution: Use subprocess with list arguments:

import subprocess
subprocess.run(["git", "log", user_input], check=True)

Issue: Path Traversal Vulnerability

Symptom:

# Vulnerable code
file_path = Path(user_input)
content = file_path.read_text()

Solution: Validate path first:

file_path = Path(user_input).resolve()
if ".." in str(file_path):
    raise ValueError("Path traversal detected")
