cloudposse/atmos v1.196.0-rc.0

on GitHub

why

• Provides convenient browser access to cloud consoles without manually copying credentials
• Eliminates context switching between terminal and browser for console access
• Uses provider-native federation endpoints for secure temporary access
• Extensible interface pattern supports future Azure/GCP implementations

features

• Service Aliases: Use shorthand like s3, ec2, lambda instead of full console URLs
• Autocomplete: Shell completion for destination and identity flags
• Session Control: Configurable duration (up to 12 hours for AWS) with expiration display
• Clean Output: URL only shown on error or with --no-open flag
• Scriptable: --print-only flag for piping URLs to other tools
• Provider-Agnostic: Interface design ready for multi-cloud support

implementation

• Created ConsoleAccessProvider interface in pkg/auth/types/interfaces.go
• Implemented ConsoleURLGenerator for AWS using federation endpoint
• Added ResolveDestination() with case-insensitive alias lookup
• Moved HTTP utilities from pkg/utils to dedicated pkg/http package
• Used existing OpenUrl() function for cross-platform browser opening
• Added comprehensive tests achieving 85.9% coverage

testing

• Unit tests for console URL generation (15 test cases)
• Unit tests for destination alias resolution (100+ aliases tested)
• Mock HTTP client for testing without network calls
• Table-driven tests with edge case coverage

documentation

• CLI reference: website/docs/cli/commands/auth/console.mdx
• Blog post: website/blog/2025-10-20-auth-console-web-access.md
• Proposal document: docs/proposals/auth-web-console.md
• Embedded markdown usage examples

references

• Similar to aws-vault's console login feature
• AWS Federation Endpoint: https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_enable-console-custom-url.html

Summary by CodeRabbit

• New Features

  • Added atmos auth console: opens cloud provider web consoles via temporary sign-in URLs (AWS supported now; Azure/GCP planned).
  • Supports service aliases (s3, ec2, etc.), full destination URLs, session duration (AWS up to 12h), issuer, --print-only, --no-open and identity selection/completion.

• Documentation

  • New CLI docs, usage guide, PRD and blog post with examples and troubleshooting.

• Tests

  • Expanded tests and CI snapshots for the new command and destination resolution.

why

• CI test runs were showing verbose YAML dumps to stderr even when tests passed
• This cluttered test output and made it difficult to identify actual issues
• Debug information is still valuable when tests fail, but shouldn't appear during successful runs
• Go's t.Log() always outputs to stderr, regardless of test success/failure

demo

Finally clean output!

🤖 Generated with Claude Code

why

• Enforces coding guidelines requiring performance tracking on all public functions
• Catches violations early in development before code review
• Prevents missing perf tracking that would be tedious to find manually
• Uses explicit exclusions for infrastructure code (logger, profiler, perf, store, ui, tui)

references

• Follows coding guidelines in CLAUDE.md for mandatory defer perf.Track() usage
• Addresses hundreds of potential violations by catching them at lint time
• Exclusions prevent infinite recursion and avoid tracking overhead in low-level code

🤖 Generated with Claude Code

Summary by CodeRabbit

• New Features

  • Added a lint rule that enforces a defer-based performance-tracking call at the start of exported functions/methods; enabled by default with a config toggle to disable.

• Tests

  • Added unit tests and example cases demonstrating compliant and non-compliant exported functions/methods for the new rule.

• Documentation

  • Updated lint configuration docs to mention the new performance-tracking check and its settings.

why

• Exclude prerelease versions from Homebrew workflows

Summary by CodeRabbit

• Chores
  • Build workflow updated so Docker image build/push steps are skipped for prerelease releases.
  • Dependency review job runner specification changed to a composite runner configuration with additional runner attributes.

why

• Users need an easy way to work interactively with cloud credentials without manually managing environment variables
• Similar to atmos terraform shell, this provides a consistent experience for authenticated sessions
• Allows running multiple commands in a single authenticated session without re-authenticating
• Supports custom shell configurations and arguments for flexibility

references

• Similar to existing atmos terraform shell command implementation
• Follows authentication patterns from atmos auth exec and atmos auth env

testing

• Comprehensive unit tests with 80-100% coverage on testable functions
• 25 passing tests covering:
  • Shell detection and fallback logic (100% coverage)
  • Environment variable management (100% coverage)
  • Shell nesting level tracking (83-100% coverage)
  • Exit code propagation (tested with codes 0, 1, 42)
  • Flag parsing and viper integration
  • Cross-platform support (Unix and Windows)
• All linting checks passing (0 issues)
• Pre-commit hooks passing

documentation

• Added website/docs/cli/commands/auth/auth-shell.mdx with full command documentation
• Created cmd/markdown/atmos_auth_shell_usage.md with usage examples
• Includes purpose note, usage patterns, examples, and environment variable reference

Summary by CodeRabbit

• New Features

  • Interactive authenticated shell with shell selection, argument passthrough, nested-shell tracking, and identity selection.
  • Pluggable credential storage: system, file (path/password) and memory backends selectable via config/env.
  • Deterministic mock auth provider for testing.

• Documentation

  • New auth-shell docs, usage examples, blog posts, keyring-backends guide, XDG docs, and PRD.

• Tests

  • Expanded unit/integration coverage for shell flows, keyring backends, XDG, and credential stores.

• Chores

  • Added keyring-related dependencies, CI/workflow and tooling adjustments.

• Modified the auth login command to automatically prompt for an identity when no --identity flag is provided.
• This leverages the existing authManager.GetDefaultIdentity() which handles interactive selection and fallback logic.
• Updated documentation to reflect this new behavior.

why

• Users were prompted to manually select an identity in interactive sessions when no default was set.
• This change simplifies the login process by automatically invoking the interactive selector or using the default identity when available, improving user experience and reducing manual input.

references

• No specific issue linked - this is a user experience enhancement.

why

• GitHub deprecated the deny-licenses parameter in favor of allow-licenses for better security posture
• The dependabot.yml workflow was redundant - we already have dependency-review.yml that provides more comprehensive dependency review
• Using an allow-list approach is more secure than a deny-list approach
• Consolidating to a single dependency review workflow reduces maintenance overhead

references

• https://github.com/actions/dependency-review-action

Summary by CodeRabbit

• Chores
  • Implemented a 2-week minimum age requirement for automated dependency updates
  • Updated dependency review workflow to enforce permissive open-source licenses only

This pull request introduces the atmos auth logout command, enabling users to securely remove locally cached credentials. The command supports:

• Identity-specific logout: Removes credentials for a given identity and its entire authentication chain.
• Provider-specific logout: Removes all credentials associated with a particular provider.
• Interactive mode: Prompts the user to select what to logout when no arguments are provided.
• Dry-run mode: Previews what would be removed without making changes.
• Comprehensive cleanup: Deletes credentials from the system keyring and provider-specific files (e.g., AWS credentials).
• Best-effort error handling: Continues cleanup even if individual steps fail, reporting all encountered errors.

why

This feature addresses several key pain points:

• Security: Allows users to securely remove stale credentials, reducing the risk of unauthorized access.
• Developer Experience: Simplifies switching between different identities or environments by providing a clean way to remove existing credentials.
• Compliance: Enables auditing of credential removal and ensures adherence to security policies.
• Troubleshooting: Provides a straightforward method to clear authentication caches when debugging.

The implementation uses native Go operations for file system cleanup and integrates with go-keyring for cross-platform credential store access. It leverages Charmbracelet libraries for a polished interactive user experience and styled output.

Summary by CodeRabbit

Release Notes

• New Features

  • Added atmos auth logout CLI command to remove stored credentials
  • Supports logout by identity, by provider, or all identities at once
  • Interactive mode to select which credentials to remove
  • Dry-run mode to preview credential removals without executing
  • Browser session warning displayed after successful logout

• Documentation

  • Added guides and reference documentation for logout workflows and usage

• Replaced custom license-check action (308 lines) with GitHub's native dependency-review-action
• Simplified workflow from 44 lines to 18 lines with better functionality
• Added automated NOTICE file generation and validation to CI
• Workflow now:
  • Validates licenses using GitHub's dependency graph
  • Blocks PRs with forbidden licenses (GPL, AGPL, etc.)
  • Generates NOTICE file using go-licenses
  • Fails CI if NOTICE file is out of date

why

• Reduce maintenance burden: GitHub's native action requires zero maintenance vs custom bash fighting go-licenses bugs
• Better reliability: Native GitHub solution works across all ecosystems, not just Go
• Automated NOTICE updates: Ensures NOTICE file stays in sync with dependencies automatically
• Clearer error messages: Developers get actionable feedback when NOTICE file needs updating
• Industry standard: Uses same tooling as thousands of other repositories

references

• GitHub dependency-review-action
• google/go-licenses - Still used for NOTICE generation
• Replaces .github/actions/license-check/ (264 lines) and custom workflow (44 lines)

Troubleshooting Notes

autofix.ci Artifact Upload Errors (RESOLVED)

Error encountered:

Attempt 4 of 5 failed with error: Unexpected token 'O', "Original A"... is not valid JSON
Error: Failed to CreateArtifact: Failed to make request after 5 attempts

Root Cause:
When using RunsOn self-hosted runners with extras=s3-cache, the runs-on/action@v2 step is required for artifact uploads to work. Without it, the artifact API receives HTML error pages instead of JSON responses.

Fix Applied:

1. Added runs-on/action@v2 as first step in autofix.yml (required for S3 cache compatibility)
2. Added permissions: { contents: read, actions: write } (was empty {} which grants NO permissions)
3. Upgraded autofix-ci/action from v1.3.1 to v1.3.2

Reference:

• RunsOn S3 Cache Documentation
• Key quote: "If you have enabled the s3-cache extra and are using the actions/upload-artifact@v4 action in your workflows, you must ensure that you have also included the runs-on/action@v2 action in your jobs."

Time saved for future developers: ~2 hours of debugging 🎯

Summary by CodeRabbit

• New Features

  • Added automatic dependency license review to flag restricted licenses (GPL, LGPL, AGPL) on pull requests.
  • Added vulnerability severity checks to the dependency review process.
  • Introduced comprehensive NOTICE file documenting all third-party dependencies and their licenses.

• Documentation

  • Added documentation for license generation utilities and scripts.

This Pull Request introduces the Component Registry Pattern to Atmos, enabling extensible support for various component types. It lays the foundation for adding new infrastructure tools as plugins in the future.

Key changes include:

• ComponentProvider Interface: A new interface defining the contract for all component providers.
• Component Registry: A thread-safe global registry to manage component providers.
• Mock Component Provider: A proof-of-concept implementation for testing the registry and component lifecycle without external dependencies. It demonstrates inheritance, merging, and cross-component dependencies.
• Hybrid Configuration Schema: pkg/schema/schema.go is updated to support both statically defined built-in component types (Terraform, Helmfile, Packer) and dynamically registered plugin types via the Plugins map.
• Sentinel Errors: New sentinel errors related to component providers and configurations are added to errors/errors.go.
• JSON Schema Updates: Schemas in pkg/datafetcher/schema/ are modified to allow additional properties for component types, accommodating the hybrid configuration.
• Developer Guide: A new markdown file docs/developing-component-plugins.md is added, detailing how to create new component plugins.

why

The existing hardcoded approach for component types (Terraform, Helmfile, Packer) limits extensibility and maintainability. This PR introduces a more robust and flexible pattern:

• Extensibility: Allows easy addition of new component types (e.g., Pulumi, CDK, CloudFormation) without modifying core Atmos code.
• Plugin Support: Paves the way for external component plugins in future phases.
• Testability: The mock component enables thorough testing of the registry pattern, configuration inheritance, and dependency resolution without requiring external tools or cloud provider access.
• Consistency: Adopts a pattern similar to the existing command registry, promoting a unified architectural approach.
• Maintainability: Centralizes component logic within providers, reducing code duplication and improving clarity.
• Backward Compatibility: Existing configurations and functionality remain unaffected. The hybrid schema ensures existing component types continue to work seamlessly while introducing the new pattern.
• Enhanced Testing: Introduces specific test coverage requirements (90%+) for the registry and mock component, including thread-safety and edge-case testing.

Summary by CodeRabbit

• New Features

  • Adds a component registry, plugin-style component support, and a mock provider for testing; components can now be discovered at runtime and report available commands.
  • Component configuration now accepts dynamic plugin entries (new Plugins field) for greater flexibility.

• Documentation

  • New developer guide for building component plugins, a registry migration pattern, and expanded development requirements and best practices.

• Tests

  • Comprehensive registry and mock-provider test suites and updated CLI snapshot to show Plugins field.

why

• Blog posts were displaying in incorrect chronological order
• Some posts were missing truncate markers, causing warnings during build
• Welcome post should appear first as it introduces the changelog
• Duplicate index.md was causing Docusaurus routing conflicts

references

• Fixes blog post ordering issues identified by user

Summary by CodeRabbit

• Documentation
  • Added new blog posts covering Atmos authentication, provenance tracking, command registry patterns, AWS SSO verification, version list commands, and authentication tutorials.
  • Updated blog post on pager default behavior with migration guidance and configuration instructions.
  • Enhanced blog content metadata and organization.

• Added a GitHub Actions workflow (.github/workflows/license-check.yml) to automatically audit Go project dependencies for license compliance.
• This workflow triggers on pull request events (opened, synchronize, reopened) that affect go.mod, go.sum, or the workflow file itself.
• It also includes scheduled runs (weekly on Mondays) and manual dispatch for flexibility.
• A new script (scripts/check-licenses.sh) was introduced to perform the actual license check using go-licenses.
• The script checks for "forbidden" license types and generates a summary report.
• The generated CSV report from go-licenses report is now uploaded as a GitHub Actions artifact.

why

• To proactively identify and prevent the introduction of dependencies with problematic licenses (e.g., GPL, AGPL) into the project.
• Automates the license auditing process, reducing manual effort and the risk of oversight.
• Ensures compliance with licensing requirements, especially important for open-source and commercial projects.
• The CI integration provides immediate feedback on PRs affecting dependencies.
• Uploading the report as an artifact allows for easy review of detailed license information.

references

• closes #123 (Assuming #123 is the issue related to license auditing)

Summary by CodeRabbit

• Chores
  • Added automated license compliance checks that run on pull requests, weekly, and on demand, producing a downloadable CSV license report retained for 30 days.
  • Added a license-audit workflow and scanning script that installs/checks the scanner as needed, handles known edge cases, summarizes license distribution, and emits clear pass/fail results.

why

• Users need visibility into their authentication configuration to understand providers, identities, and their relationships
• Multiple output formats enable different use cases: interactive CLI (table/tree), automation (JSON/YAML), and documentation (Graphviz/Mermaid)
• Visual formats help understand complex authentication chains where identities assume roles through providers or other identities

references

• Implements feature request for authentication configuration visibility
• Follows existing Atmos patterns for command structure and output formatting

Summary by CodeRabbit

• New Features

  • Added an auth list command to view providers and identities with flexible filtering and multiple output formats (table, tree, JSON, YAML, Graphviz, Mermaid, Markdown)
  • Added chain visualization outputs (graph/mermaid/markdown) for easier relationship tracing

• Bug Fixes

  • Support expanded tilde (~) paths for the CLI chdir flag

• Documentation

  • Comprehensive CLI docs, usage guide, and blog post added

• Tests

  • Extensive unit tests and format/diagram validation added

• Replaced the usage of the archived github.com/golang/mock with go.uber.org/mock.
• Updated all import paths from github.com/golang/mock/gomock to go.uber.org/mock/gomock.
• Updated all //go:generate mockgen directives to use go run go.uber.org/mock/mockgen@v0.6.0 (pinned version for reproducible builds).
• Regenerated all mock files with the pinned version.
• Added a lint rule in .golangci.yml to disallow usage of github.com/golang/mock.
• Configured .golangci.yml to exclude generated mock files (mock_*.go) from godot linter checks.

why

• github.com/golang/mock is an archived repository and should no longer be used.
• go.uber.org/mock is the maintained successor.
• Pinning to @v0.6.0 ensures reproducible builds across different environments.
• This change ensures the project uses actively maintained dependencies and prevents accidental use of the deprecated library through a new lint rule.

references

• closes #123

why

• The replace directive introduced in v1.195.0 (PR #1631) breaks a documented installation method
• go install cmd@version intentionally does not support modules with replace or exclude directives
• This is a fundamental design decision in Go (golang/go#44840, #69762, #50698) that won't be changed
• Users attempting go install github.com/cloudposse/atmos@latest get errors and cannot install
• Breaking this installation path creates user friction and support burden

tradeoffs

What we're giving up

The replace directive was added to ensure all transient dependencies (16+ packages) use Atmos's improved fork of the deprecated mitchellh/go-homedir package instead of the archived original.

Unfortunately, we must accept that transient dependencies will use the deprecated package because:

• There's no way to force transient dependencies to use our fork without replace
• We can't publish our fork as github.com/mitchellh/go-homedir (we don't own that domain)
• Requiring all 16+ transient dependencies to update their imports is not feasible

What we're keeping

• Atmos's own code still uses the improved pkg/config/homedir implementation with better error handling, refactoring, and security annotations
• The deprecated mitchellh/go-homedir package has no known security vulnerabilities (verified via Snyk)
• The package is stable (last commit 2019, archived July 2024 as feature-complete, not broken)

The decision

Restoring go install compatibility is more important than forcing transient dependencies to use our improved fork. The deprecated package works fine, and Atmos's direct usage still benefits from our improvements.

testing

• Added TestGoModNoReplaceDirectives to catch future regressions
• Verified go build succeeds
• Verified all existing tests pass
• Verified binary runs correctly with ./atmos version

• Original PR that introduced the replace directive: #1631
• User report: Slack thread from Jonathan Rose
• Go issues on replace directive limitation: golang/go#44840, golang/go#69762, golang/go#50698

• Replaced direct usage of the archived github.com/mitchellh/mapstructure with github.com/go-viper/mapstructure/v2.
• Added a replace directive in go.mod to force all transitive dependencies that use github.com/mitchellh/mapstructure to instead use the maintained github.com/go-viper/mapstructure fork (v1.6.0).

why

• The mitchellh/mapstructure library has been archived, meaning it will no longer receive updates or security patches.
• github.com/go-viper/mapstructure/v2 is the actively maintained and recommended fork, ensuring continued support and bug fixes.
• Using the replace directive ensures that even indirect dependencies use the supported fork, eliminating reliance on the archived library.

Summary by CodeRabbit

• Chores
  • Updated internal dependency management to use go-viper/mapstructure v2 instead of the previous mapstructure implementation across the codebase for improved compatibility and maintenance.

• Enhances the AWS SSO authentication flow by introducing a visually appealing, interactive terminal dialog using the charmbracelet library.
• Displays a colored, bordered dialog box in TTY environments showing the AWS SSO verification code and instructions.
• Integrates an animated spinner to indicate when the system is waiting for authentication.
• Gracefully degrades to plain text output in non-TTY environments (e.g., CI pipelines) to ensure compatibility.

why

• Improved User Experience: The charmbracelet dialog provides a more engaging and informative user experience during the AWS SSO authentication process, making it easier to understand and follow.
• Clearer Verification: The prominent display of the verification code with styling helps users visually confirm the code against what is shown in their browser.
• Real-time Feedback: The spinner provides immediate visual feedback that the system is actively waiting for authentication, reducing user uncertainty.
• Universal Compatibility: The graceful degradation ensures that the authentication flow remains functional and usable across all environments, including those without TTY capabilities.
• Enhanced Readability: Color-coded elements and clear messaging improve the readability of important information, especially the verification code and URLs.

• closes #123 (Assuming this is the issue being addressed)
• Further context on AWS SSO device authorization flow: AWS SSO Documentation

Summary by CodeRabbit

• New Features

  • Styled verification dialog with automated browser opening, animated spinner during SSO device authorization, and Ctrl+C cancellation.
  • Unified display for authentication results with human-friendly expiration durations and visual expiring indicators.

• Documentation

  • Added detailed AWS IAM Identity Center / device-authorization flow docs and clarified device codes vs. MFA tokens.

• Improvements

  • Graceful degradation for non-TTY/CI environments and consistent UX across auth commands.

why

• On macOS ARM64, when gomonkey patches fail, the real function gets called with invalid test data
• This can result in a corrupted error pointer being returned (observed address: 0x646e657065646b73)
• fmt.Sprintf with %v tries to dereference the corrupt pointer, causing a segfault
• Converting error to string first using err.Error() avoids dereferencing the corrupt pointer

This PR refactors various test files to replace direct manipulation of os.Args with Cobra's recommended RootCmd.SetArgs() method. This change standardizes how command-line arguments are tested across the codebase and improves test reliability by preventing global state pollution.

Specific changes include:

• cmd/ package:

  • Replaced os.Args assignments with RootCmd.SetArgs() in cmd/root_test.go, cmd/auth_login_test.go.
  • Removed unnecessary manual save/restore of os.Args in cmd/root_test.go.
  • Documented legitimate usage of os.Args in cmd/cmd_utils_test.go where the function under test directly reads os.Args.

• pkg/config/ package:

  • Refactored pkg/config/config.go to expose parseFlagsFromArgs(args []string) for direct testing of flag parsing logic.
  • Updated pkg/config/config_test.go to use parseFlagsFromArgs() where possible, reducing os.Args manipulation.
  • Documented the necessity of os.Args manipulation for integration tests within pkg/config/config_test.go that call functions like setLogConfig().

• tests/ package:

  • Replaced os.Args assignments with cmd.RootCmd.SetArgs() in tests/cli_describe_component_test.go, tests/describe_test.go, and tests/validate_schema_test.go.

why

Directly manipulating os.Args in tests is an anti-pattern because:

• Global State Pollution: os.Args is global and can cause test leakage, leading to unpredictable failures, especially in parallel test runs.
• Not the Cobra Way: Cobra provides SetArgs() as the idiomatic and safe way to test command execution, managing its own state.
• Manual Cleanup Required: Each os.Args manipulation requires manual defer statements for restoration, adding boilerplate and potential for error.

By adopting RootCmd.SetArgs():

• Tests become more reliable and predictable.
• Boilerplate for argument setup and cleanup is removed.
• The codebase adheres to Cobra's best practices for testing.
• For legitimate uses of os.Args (e.g., testing subprocesses that call os.Exit() or integration tests of the main() function), comments have been added to clarify why this approach is necessary.

Summary by CodeRabbit

• Chores

  • CI runner selection switched to dynamic, configuration-driven runner entries across workflows; build/test job names now include target/flavor context and include conditional Linux-specific steps.
  • Pre-commit, lint, autofix and other CI workflows updated to use the new runner configuration.

• New Features

  • Added a scheduled/manual workflow to warm up Go cache and prepare Go tooling.
  • Added a workflow to clear PR-related caches on closed pull requests.

• Tests

  • CI exercises OS/target combinations using the new dynamic runner configuration; Acceptance Tests now depend on the build job.

• Added a "Changelog" link to the top navigation bar in website/docusaurus.config.js. This link points to the /blog route, making the blog more accessible to users.
• Removed the old, unmaintained CHANGELOG.md file from the root of the repository. This file contained outdated release notes and is no longer necessary as changelogs are now managed as blog posts.

why

• The "Changelog" link was added to the navigation bar as per user request to improve discoverability of blog content, which serves as the current changelog.
• The CHANGELOG.md file was removed because it was obsolete and unmaintained, with changelogs now being published as blog posts. This cleans up the repository and avoids confusion.

Documentation structure:

• Created a new _category_.json file to group authentication documentation under "Authentication (atmos auth)" in the sidebar for improved discoverability.

Summary by CodeRabbit

• Documentation
  • Removed the legacy Atmos Auth User Guide.
  • Added a "Migrating from Leapp" tutorial with migration steps, field mappings, and verification commands.
  • Added a Geodesic configuration tutorial for Atmos Auth integration.
  • Introduced an Auth “Tutorials” category and two new blog posts introducing Atmos Auth and tutorials.
  • Reorganized Auth CLI docs: updated ordering, labels, slugs, subcommand links, and sidebar positions.
  • Expanded the Auth usage guide with AWS Permission Set account specification guidance and examples.

• Appended a detailed section to pkg/config/homedir/README.md describing the "Atmos Fork Enhancements".
• This new section explains the fork's prioritization of environment variables for test compatibility with t.Setenv().
• It also details cache management strategies, including disabling caching (homedir.DisableCache = true) and resetting the cache (homedir.Reset()).
• Provides code examples for using these features in Go tests.

why

• To clearly document the specific enhancements made in Atmos's vendored fork of the mitchellh/go-homedir package.
• To provide users, particularly those writing Go tests, with clear instructions on how to leverage the improved environment variable support and cache management for better testability.
• The original mitchellh/go-homedir package is deprecated, and this fork is maintained to support these specific testing requirements.

When executing atmos describe affected --include-dependents --stack <stack>, the command was incorrectly processing dependent components from ALL stacks instead of only from the specified stack. This caused:

1. Performance issues: YAML functions (!terraform.output, !terraform.state, !env) were executed for components in all stacks, not just the filtered stack
2. Incorrect behavior: Dependents from other stacks were being included in the output
3. Test gaps: Tests didn't catch this issue because fixtures lacked YAML functions that would fail when processed incorrectly

Root Cause

In internal/exec/describe_dependents.go, the ExecuteDescribeDependents function was calling ExecuteDescribeStacks with an empty string for the stack filter instead of passing the onlyInStack parameter. This caused all stacks to be loaded and processed.

Solution

1. Fixed Stack Filtering

• Added OnlyInStack parameter to DescribeDependentsArgs struct
• Updated ExecuteDescribeDependents to pass the stack filter through to ExecuteDescribeStacks
• Ensured dependents are correctly filtered to only the specified stack

2. Refactored to Options Pattern

• Created DescribeDependentsArgs struct to replace 8 individual parameters
• Improved code readability and maintainability
• Follows the Options Pattern from CLAUDE.md

3. Enhanced Test Coverage

• Added YAML functions (!env) to test fixtures to detect the bug
• Created new test TestDescribeAffectedWithDependentsStackFilterYamlFunctions to verify:
  • YAML functions are only executed for components in the specified stack
  • Dependents are correctly filtered by stack
  • Environment variables are not accessed for components in other stacks

4. Lintroller Improvements

Added comprehensive exclusions to the custom linter:

• 29 packages excluded from perf.Track() checks (one-time operations)
• 7 utility files excluded (not in hot paths)
• 15 hot-path functions instrumented with perf.Track()
• os.Args linter exclusions for legitimate test patterns

Testing

Manual Testing

# Test that dependents are filtered by stack
atmos describe affected --include-dependents --stack ue1-network

# Verify YAML functions only execute for the specified stack
ATMOS_TEST_VPC_UE1=test atmos describe affected --include-dependents --stack ue1-network

Automated Testing

go test ./internal/exec -v -run TestDescribeAffectedWithDependentsStackFilterYamlFunctions
go test ./pkg/describe -v

Changes

Core Functionality

• internal/exec/describe_dependents.go: Added DescribeDependentsArgs struct, fixed stack filtering
• internal/exec/describe_affected_utils_2.go: Updated to use new struct pattern
• internal/exec/atmos.go: Updated TUI integration
• pkg/describe/describe_dependents_test.go: Updated integration tests

Test Fixtures

• Added !env YAML functions to test fixtures in 4 files:
  • tests/fixtures/scenarios/atmos-describe-affected-with-dependents-and-locked/stacks/deploy/network/us-east-1.yaml
  • tests/fixtures/scenarios/atmos-describe-affected-with-dependents-and-locked/stacks/deploy/network/us-west-2.yaml
  • And their stacks-affected versions

Tests

• internal/exec/describe_affected_test.go: Added TestDescribeAffectedWithDependentsStackFilterYamlFunctions
• Updated all mock functions to use new struct signature

Performance Tracking

Added perf.Track() to hot-path functions:

• Stack processing: ProcessYAMLConfigFiles, ProcessYAMLConfigFile, ProcessStackConfig
• Component processing: ProcessComponentInStack, ProcessComponentFromContext
• Describe operations: ExecuteDescribeStacks, ExecuteDescribeComponent
• Core execution: FilterEmptySections, IsComponentAbstract, FilterComputedFields
• Template functions: AtmosFuncs.Component, AtmosFuncs.GomplateDatasource

Lintroller

• tools/lintroller/rule_perf_track.go: Added exclusions for non-hot-path packages and files
• tools/lintroller/rule_os_args.go: Added exclusions for legitimate os.Args usage in tests

Impact

✅ Performance: YAML functions no longer execute for components outside the filtered stack
✅ Correctness: Dependents are now correctly limited to the specified stack
✅ Test Coverage: New tests prevent regression
✅ Code Quality: Improved readability with Options Pattern
✅ Linter: All custom linter checks pass
