name: atlas-standard description: Standard 5-phase workflow for most development tasks - bugs, small features, refactors (30-60 min)

Atlas Standard Workflow

When to Use This Skill

Perfect for (80% of tasks):

• Bug fixes (2-5 files affected)
• Small features (clear requirements)
• Code refactoring
• Test additions
• Logic changes with moderate complexity

Time estimate: 30-60 minutes

Success criteria:

• Feature complete in < 2 hours
• All edge cases covered
• Tests pass
• Peer review approved

The 5 Phases

Phase 1: Research      → Understand current implementation
Phase 2: Plan          → Design approach
Phase 3: Implement     → Make changes + tests
Phase 4: Review        → Edge cases + security
Phase 5: Deploy        → Full test suite + deployment

---

Phase 1: Research

Goal: Understand the current implementation and identify all affected files.

Steps:

1. Find all related files

   # Search for relevant code patterns
   grep -r "featureName" src/
   grep -r "ComponentName" src/
   
   # Find component/function usage
   grep -r "import.*ComponentName" src/
   

2. Understand current implementation

   • Read the main file(s) involved
   • Trace data flow
   • Identify dependencies
   • Note platform-specific code (if multi-platform)

3. Check for existing patterns

   • Look for similar implementations
   • Identify coding patterns to follow
   • Review related tests

4. Identify potential impacts

   • Which components use this code?
   • Are there platform-specific considerations?
   • What tests cover this area?

Output:

• List of files to modify
• Understanding of current implementation
• Potential risks identified

Research Checklist:

For data/state changes:

• Which state management system? (Redux, Zustand, Context, etc.)
• Which update pattern to use?
• Are there naming conventions to follow?
• Check for data normalization utilities

For UI changes:

• Platform-specific files? (if multi-platform)
• Component library conventions?
• Accessibility requirements?
• Design system rules?

For API/integration changes:

• Check authentication patterns
• Error handling conventions
• Data validation requirements

Example Research Output:

Files to modify:
- /src/services/api/userService.js (main API logic)
- /src/store/userStore.js (state updates)
- /src/utils/validation.js (data validation)

Current implementation:
- API calls use fetch with manual error handling
- State updates use direct mutations
- No data validation on responses

Risks:
- Must preserve backward compatibility with existing API consumers
- Need to handle edge cases for malformed responses

---

Phase 2: Plan

Goal: Design the approach and create a file-by-file implementation plan.

Steps:

1. Design the solution

   • How will you fix the bug / implement the feature?
   • What's the cleanest approach?
   • Are there edge cases to handle?

2. List file changes

   • File 1: What changes?
   • File 2: What changes?
   • Tests: What new tests?

3. Identify dependencies

   • What order to make changes?
   • Any breaking changes?
   • Backwards compatibility needed?

4. Plan testing approach

   • What tests to add/modify?
   • How to verify manually?
   • Platform-specific testing needed?

Output:

• Clear implementation plan
• File-by-file change list
• Testing strategy

Planning Best Practices:

State management strategy:

• Identify which state containers to update
• Use project-specific update patterns
• Plan for optimistic updates if applicable

Code organization:

• Follow project file structure conventions
• Consider separating concerns (business logic vs UI)
• Plan for reusability

Testing strategy:

• Unit tests for business logic
• Integration tests for workflows
• Manual testing checklist

Example Plan:

Solution Design:
- Refactor API error handling into reusable utility
- Add response validation layer
- Update state management to use immutable updates

File Changes:
1. /src/utils/apiHelpers.js
   - Create handleApiError() function
   - Create validateResponse() function
   - Add retry logic for network failures

2. /src/services/api/userService.js
   - Replace inline error handling with apiHelpers
   - Add response validation before state updates

3. /src/store/userStore.js
   - Update state mutations to use immutable patterns
   - Add error state management

4. /tests/services/api/userService.test.js
   - Add test: "handles API errors gracefully"
   - Add test: "validates response structure"
   - Add test: "retries failed requests"

Testing Approach:
- Unit tests for error handling utilities
- Integration test for full API flow
- Manual test: Simulate network failure scenarios

---

Phase 3: Implement

Goal: Make the changes and update tests.

Steps:

1. Implement changes file-by-file

   • Follow the plan from Phase 2
   • Use project conventions
   • Add code comments for complex logic

2. Update/add tests

   • Add tests for new functionality
   • Update existing tests if behavior changed
   • Ensure tests cover edge cases

3. Verify locally

   • Run tests: npm test (or your test command)
   • Run linting: npm run lint (or your lint command)
   • Test manually if UI changes

4. Follow project conventions

   • Use consistent naming patterns
   • Follow code style guidelines
   • Apply project-specific best practices

Implementation Checklist:

Before writing code:

• Understand the pattern to follow (research phase complete)
• Know which update methods to use
• Naming conventions clear

During implementation:

• Use project-specific state update patterns
• Follow naming conventions
• Include proper error handling
• Remove debug logs or make them conditional
• Add comments for non-obvious logic

After implementation:

• All imports correct
• No debug statements left in code
• Tests added/updated
• Validation checks pass

Code Quality Guidelines:

State updates:

// Follow your project's state management pattern
// Examples:

// Redux pattern:
dispatch(updateUser(userData))

// Zustand pattern:
useStore.getState().updateUser(userData)

// Context pattern:
setUser(prevUser => ({ ...prevUser, ...userData }))

Error handling:

// Consistent error handling
try {
  const result = await riskyOperation()
  return result
} catch (error) {
  logger.error('Operation failed', error)
  throw new AppError('User-friendly message', error)
}

Conditional debugging:

// Debug logs only in development
if (process.env.NODE_ENV === 'development') {
  console.log('Debug info:', data)
}

// Or use your project's logger
logger.debug('Debug info:', data)  // Won't log in production

Example Implementation:

// File: /src/utils/apiHelpers.js

/**
 * Handles API errors consistently across the application
 */
export const handleApiError = (error) => {
  // Log for debugging (only in development)
  if (process.env.NODE_ENV === 'development') {
    console.error('API Error:', error)
  }

  // Extract user-friendly message
  const message = error.response?.data?.message ||
                  error.message ||
                  'An unexpected error occurred'

  // Return standardized error object
  return {
    type: 'API_ERROR',
    message,
    status: error.response?.status,
    originalError: error
  }
}

/**
 * Validates API response structure
 */
export const validateResponse = (response, schema) => {
  if (!response) {
    throw new Error('Response is null or undefined')
  }

  // Validate against expected schema
  if (schema.required) {
    for (const field of schema.required) {
      if (!(field in response)) {
        throw new Error(`Missing required field: ${field}`)
      }
    }
  }

  return response
}

---

Phase 4: Review

Goal: Peer review for edge cases and security check.

Steps:

1. Self-review first

   • Re-read all changed files
   • Check for edge cases
   • Verify conventions followed
   • Confirm error handling added

2. Run validation commands

   npm run lint
   npm test
   npm run build  # Ensure it builds
   

3. Invoke peer-reviewer (if using Atlas agents)

   • Provide context: "Review my changes for [feature/bug]"
   • Address feedback
   • Re-run validation after fixes

4. Security check (if applicable)

   • Handling user data? Verify sanitization
   • External API calls? Verify authentication
   • User input? Verify validation
   • Secrets? Verify not hardcoded

Review Checklist:

Code quality:

• Follows project coding standards
• No debugging statements
• Clear variable/function names
• Comments for complex logic
• No copy-paste duplication

Project conventions:

• State management patterns followed
• Naming conventions correct
• Error handling consistent
• Logging appropriate

Platform compatibility (if applicable):

• Cross-platform code works everywhere
• Platform-specific code properly isolated
• No platform-specific APIs in shared code

Edge cases:

• Null/undefined handling
• Empty array/object handling
• Backwards compatibility with old data
• Migration path for breaking changes

Testing:

• Tests cover main functionality
• Tests cover edge cases
• All tests pass
• Build succeeds

Security:

• No hardcoded secrets or credentials
• User input properly validated
• External data properly sanitized
• Authentication/authorization correct

Common Review Issues:

Issue 1: Inconsistent error handling

// Found during review
try {
  await operation()
} catch (e) {
  console.log(e)  // Inconsistent with project pattern
}

// Fixed
try {
  await operation()
} catch (error) {
  logger.error('Operation failed', error)
  throw new AppError('User-friendly message', error)
}

Issue 2: Missing validation

// Found during review
const user = response.data
setUser(user)  // No validation!

// Fixed
const user = validateResponse(response.data, userSchema)
setUser(user)

Issue 3: Edge case not handled

// Found during review
const firstItem = items[0]  // Crashes if empty

// Fixed
const firstItem = items.length > 0 ? items[0] : null
if (!firstItem) return null

---

Phase 5: Deploy

Goal: Run full test suite and deploy via project process.

Steps:

1. Document changes (follow your project's process)

   • Update changelog if applicable
   • Update version numbers if needed
   • Document breaking changes

2. Run full validation

   npm run lint
   npm test
   npm run build
   # Add any project-specific validation commands
   

3. Deploy using project process

   • Follow your deployment workflow
   • May involve: git push, CI/CD pipeline, manual deployment
   • Ensure you're deploying to the correct environment

4. Verify deployment

   • Check deployment output for errors
   • Verify changes in target environment
   • Monitor for issues

Deployment Checklist:

Pre-deployment:

• Changes documented (changelog, release notes, etc.)
• All tests pass
• Linting passes
• Build succeeds
• Working directory clean (if required)

Deployment:

• Use established deployment process
• Deploy to correct environment
• Follow environment-specific requirements

Post-deployment:

• Deployment succeeded (no errors)
• Changes visible in target environment
• No immediate issues detected
• Monitoring shows normal behavior

Quality Gates:

Most projects enforce these automatically:

• All tests must pass
• Linting must pass
• Build must succeed
• Code review approved (if required)

If checks fail:

• Tests fail: Fix them, don't skip
• Linting fails: Fix violations
• Build fails: Debug and fix
• Never bypass quality gates without team approval

Example Deployment:

# 1. Document changes (example: update CHANGELOG.md)
## [1.2.3] - 2025-01-15
### Fixed
- API error handling now consistently formats errors
- Added response validation to prevent malformed data
- Improved retry logic for network failures

### Added

- Comprehensive test coverage for error scenarios

# 2. Run full validation
npm run lint     # Pass
npm test         # Pass (45/45 tests)
npm run build    # Success

# 3. Deploy via project process
git add .
git commit -m "Fix API error handling and add validation"
git push origin feature/api-error-handling

# Or use automated deployment:
npm run deploy:staging
# CI/CD pipeline runs, tests pass, deploys automatically

# 4. Verify
# Check deployment logs, test in staging environment

Customizing for Your Project

Atlas Standard works with any codebase. Customize by creating project-specific configuration:

Create .atlas/conventions.md

Document your project's conventions:

# Project Conventions

## State Management
- Use Redux Toolkit for global state
- Use local state (useState) for component-only state
- Always use selectors, never access state directly

## Naming Conventions
- Components: PascalCase (UserProfile.jsx)
- Utilities: camelCase (apiHelpers.js)
- Constants: UPPER_SNAKE_CASE (API_BASE_URL)

## Code Quality Standards
- No console.log in production code
- Use TypeScript strict mode
- Minimum 80% test coverage

## Platform Rules (if multi-platform)
- Web: Support Chrome, Firefox, Safari latest 2 versions
- Mobile: iOS 14+, Android 10+
- Use feature detection, not browser detection

Create .atlas/validation.sh

Add project-specific validation:

#!/bin/bash

# Project-specific validation checks
check_project_antipatterns() {
    echo "Checking project anti-patterns..."

    # Example: Check for direct state mutations
    if grep -r "state\[" src/ | grep -v "node_modules"; then
        echo "Error: Direct state mutation found (use immutable updates)"
        return 1
    fi

    # Example: Check for hardcoded API URLs
    if grep -r "https://api.example.com" src/ | grep -v "config"; then
        echo "Error: Hardcoded API URL (use config)"
        return 1
    fi

    return 0
}

# Export for use by Atlas validation scripts
export -f check_project_antipatterns

Create .atlas/deployment.md

Document deployment process:

# Deployment Process

## Environments
- **Development**: Local development, any changes
- **Staging**: Pre-production testing, deployed from main branch
- **Production**: Live environment, deployed from release tags

## Deployment Steps

### To Staging
1. Ensure all tests pass: `npm test`
2. Merge to main branch
3. CI/CD automatically deploys to staging
4. Verify in staging environment

### To Production
1. Create release branch: `git checkout -b release/v1.2.3`
2. Update version: `npm version 1.2.3`
3. Create PR to main
4. After approval and merge, tag: `git tag v1.2.3`
5. Push tag: `git push origin v1.2.3`
6. CI/CD automatically deploys to production

## Release Checklist
- [ ] All tests passing
- [ ] Version updated
- [ ] CHANGELOG.md updated
- [ ] Documentation updated
- [ ] Security review (if needed)
- [ ] Stakeholders notified

Using Custom Configuration

The Atlas validation script will automatically load your custom configuration:

# In scripts/validate-standard.sh
if [ -f .atlas/conventions.md ]; then
  echo "Loading project conventions..."
fi

if [ -f .atlas/validation.sh ]; then
  source .atlas/validation.sh
  check_project_antipatterns  # Run custom checks
fi

Success Indicators

You've succeeded when:

• Task completed in < 2 hours
• All 5 phases completed (no skipping)
• Tests pass
• Peer review approved (no major issues)
• Deployed without rollback
• Edge cases covered
• Project conventions followed

You need to escalate to Full workflow if:

• Scope expanded to 6+ files
• Security concerns emerged
• Formal requirements needed
• Architectural changes needed

---

Common Pitfalls

Don't Do This:

• Skip research phase ("I know where the bug is")
• Skip planning ("I'll figure it out as I code")
• Skip review phase ("It's a small change")
• Bypass deployment process ("Manual deployment is faster")
• Ignore project conventions
• Leave debug statements in code
• Skip tests because "it's obvious it works"

Do This Instead:

• Complete all 5 phases (they're quick for Standard tier)
• Follow project patterns consistently
• Use established state management patterns
• Remove debug statements or make them conditional
• Test thoroughly, including edge cases
• Use project deployment process

---

Resources

• Research patterns: See resources/research-patterns.md
• Validation script: See scripts/validate-standard.sh
• Project conventions: See .atlas/conventions.md (create if needed)
• Deployment process: See .atlas/deployment.md (create if needed)

Example: Full Standard Workflow

Task: "Fix bug where API errors crash the application"

Phase 1: Research (10 min)

# Find API-related files
grep -r "fetch\|axios" src/services/
grep -r "error" src/services/api/

# Files found:
# - /src/services/api/userService.js (API calls)
# - /src/store/userStore.js (state management)
# - /src/utils/errorHandling.js (error utilities)

Understanding:

• API calls use fetch with minimal error handling
• Errors throw unhandled exceptions, crashing app
• No consistent error message formatting

Phase 2: Plan (5 min)

Solution:

1. Create centralized error handler in apiHelpers.js
2. Update all API calls to use error handler
3. Add error state to store
4. Display user-friendly error messages

Files to change:

• Create /src/utils/apiHelpers.js - error handling utilities
• Update /src/services/api/userService.js - use new error handler
• Update /src/store/userStore.js - add error state
• Add /tests/utils/apiHelpers.test.js - test error handling

Phase 3: Implement (20 min)

// apiHelpers.js
export const handleApiError = (error) => {
  const message = error.response?.data?.message ||
                  'An unexpected error occurred'

  return {
    type: 'API_ERROR',
    message,
    status: error.response?.status
  }
}

// userService.js
export const fetchUser = async (id) => {
  try {
    const response = await fetch(`/api/users/${id}`)
    return await response.json()
  } catch (error) {
    const apiError = handleApiError(error)
    throw apiError
  }
}

// Add tests
test('handleApiError formats error correctly', () => {
  const error = { response: { data: { message: 'Not found' }, status: 404 } }
  const result = handleApiError(error)
  expect(result.message).toBe('Not found')
  expect(result.status).toBe(404)
})

Phase 4: Review (10 min)

Self-review checklist:

• Error handling consistent across all API calls
• User-friendly error messages
• Tests added
• No debug logs

Run validation:

npm run lint   # Pass
npm test       # Pass (12/12 tests)

Phase 5: Deploy (5 min)

# Update CHANGELOG.md
## [1.2.1] - 2025-01-15
### Fixed
- API errors now handled gracefully without crashing
- Added user-friendly error messages

# Run validation
npm test       # Pass
npm run build  # Success

# Deploy via project process
git add .
git commit -m "Fix API error handling"
git push origin main
# CI/CD deploys automatically

Total time: ~50 minutes

Summary

The Standard workflow is your daily driver for most development tasks. It provides the right balance of:

• Rigor: All 5 phases ensure quality
• Speed: Completed in 30-60 minutes
• Flexibility: Can escalate to Full if needed

When in doubt, choose Standard workflow - it's correct for 80% of tasks.
