Modify Without Fear
Enterprise-grade safety for production codebases
Scope Management
Protect critical files from modification. Define exactly what AI can touch. Never worry about accidental changes to production code.
Blast Radius Validation
See exactly what will be affected before making changes. Understand the ripple effects across your entire codebase.
Checkpoints & Rollback
Create named restore points before risky changes. Rollback instantly if something goes wrong. Experiment fearlessly.
Preview Changes
Review full diffs before any changes are applied. See exactly what will be modified, line by line.
Read-First Investigation
Understand issues before fixing them. Investigator agent explores your codebase safely without making any changes.
Smart Fixes
AI understands your codebase patterns and conventions. Every fix matches your team's style and standards.
MAINTAIN Command Suite
Six powerful commands for safe code modifications
/siftcoder:fixFix bugs and issues automatically with scoped changes. AI identifies the problem, plans the fix, validates blast radius, and applies changes safely.
What It Does
Investigates issue, plans fix, validates scope, implements changes, runs tests, and validates quality gates.
Best For
Bug fixes, error resolution, issue handling, production problems.
Usage
/siftcoder:fix "Bug description"
/siftcoder:fix "User authentication fails on mobile"
/siftcoder:investigateSafely explore your codebase to understand issues. Read-only mode analyzes code, patterns, and dependencies without making any changes.
What It Does
Explores codebase, finds relevant files, analyzes patterns, identifies root causes, and provides insights.
Best For
Understanding code, investigating bugs, exploring unfamiliar codebases, root cause analysis.
Usage
/siftcoder:investigate "Issue description"
/siftcoder:investigate "Memory leak in checkout"
/siftcoder:scopeManage which files AI can modify. Protect critical files, define safe zones, and control your blast radius.
What It Does
Adds or removes files from protection list. Shows current scope. Validates blast radius before changes.
Best For
Protecting production code, defining boundaries, team safety standards.
Usage
/siftcoder:scope add <file-pattern>
/siftcoder:scope add .env/siftcoder:scope add src/critical/*
/siftcoder:blast-radiusSee what will be affected before making changes. Validates that proposed changes won't impact protected areas.
What It Does
Analyzes proposed changes, identifies affected files, validates against scope, shows impact visualization.
Best For
Pre-change validation, impact analysis, safety checks, risk assessment.
Usage
/siftcoder:blast-radius "Change description"
/siftcoder:blast-radius "Refactor user service"
/siftcoder:checkpointCreate named restore points. Save your codebase state before risky changes. Rollback instantly if needed.
What It Does
Saves current state, manages checkpoints, lists available restore points, rolls back to checkpoints.
Best For
Pre-experiment safety, major refactoring, risky changes, rollback capability.
Usage
/siftcoder:checkpoint save "name"
/siftcoder:checkpoint save "before-refactor"
/siftcoder:previewReview full diffs before any changes are applied. See exactly what will change, line by line, with syntax highlighting.
What It Does
Shows proposed changes, displays diffs, highlights modifications, allows approval before applying.
Best For
Pre-change review, diff visualization, change approval, code review workflow.
Usage
/siftcoder:preview
Full git-style diff with +/- changes
How MAINTAIN Works
A safety-first approach to code modifications
Investigate Read-Only
Understand the issue by exploring your codebase safely. No files are modified during investigation.
Validate Blast Radius
Check what will be affected. Ensure changes won't impact protected files or systems.
Create Checkpoint
Save current state before making changes. You can always rollback if something goes wrong.
Preview Changes
Review full diffs of proposed changes. See exactly what will be modified before applying.
Apply Scoped Changes
Changes are applied only within approved scope. Protected files remain untouched.
Validate & Test
Run tests, check quality gates, ensure nothing broke. Rollback if needed.
Frequently Asked Questions
Start by protecting critical files: configuration (.env, config/), production databases, authentication systems, payment processing, and any irreplaceable code. Use /siftcoder:blast-radius before changes to see what will be affected, then add sensitive files to scope if needed.
Yes! That's a perfect use case. Save a checkpoint, try an experimental approach, test it, and either keep it or rollback to the checkpoint and try a different branch. This is ideal for refactoring, optimization experiments, and exploring alternative solutions.
The system will block the modification and notify you that the file is protected. You'll need to either remove the file from scope using /siftcoder:scope remove [file] or adjust your approach. This prevents accidental changes to critical files.
Blast radius analyzes code dependencies, imports, function calls, and data flow to identify all files that could be affected. It's highly accurate for catching direct dependencies and should be used as a safety check before any significant changes.
Absolutely! MAINTAIN safety features are built into BUILD and autonomous workflows. /siftcoder:fix automatically uses scope validation, blast radius checks, and quality gates. You can also pause autonomous workflows to use preview, checkpoint, or scope commands manually.
