…valid multiple %w verbs This fixes Go vet errors caused by using multiple %w verbs in a single fmt.Errorf call. According to Go documentation, only one %w verb is allowed per format string. Changes: - Replace all usages of ErrWrappingFormat with ErrStringWrappingFormat - Fix additional cases with multiple %w verbs by changing second %w to %s - Simplify nested fmt.Errorf calls in pkg/git/git.go Closes #1476 Fixes DEV-3616
## what - Fixed invalid error format constants in pkg/store/errors.go that used multiple %w verbs - Added comprehensive static error definitions for common error patterns - Replaced dynamic error messages with proper static error wrapping across the codebase - Ensured all error wrapping follows Go's single %w verb requirement - Added error format constants to avoid string literal duplication ## why - Go only allows one %w verb per fmt.Errorf call for proper error chain preservation - Using multiple %w verbs causes go vet failures and undefined behavior - Static errors improve maintainability, searchability, and consistency - Proper error wrapping enables reliable use of errors.Is() and errors.As() - Format constants reduce code duplication and satisfy linter requirements ## references - Fixes DEV-3616: Fix invalid ErrWrappingFormat usage with multiple %w verbs - Related PR discussion: #1475 (comment)

🧹 Nitpick comments (28)
pkg/store/redis_store.go (1)
167-173: Use a local err to avoid duplicate calls and pass it through consistently.Minor readability/efficiency tweak; also ensures the same error instance is used in both branches.
Apply this diff:
- if resp.Err() != nil { - if errors.Is(resp.Err(), redis.Nil) { - return nil, fmt.Errorf(errWrapFormatWithID, ErrResourceNotFound, redisKey, resp.Err()) - } - return nil, fmt.Errorf(errFormat, ErrGetParameter, resp.Err()) - } + if err := resp.Err(); err != nil { + if errors.Is(err, redis.Nil) { + return nil, fmt.Errorf(errWrapFormatWithID, ErrResourceNotFound, redisKey, err) + } + return nil, fmt.Errorf(errFormat, ErrGetParameter, err) + }internal/exec/yaml_func_store_get.go (1)
98-101: Prefer the shared wrapping format constant for consistency.Switch the literal "%w: ...: %s" to errUtils.ErrStringWrappingFormat to align with repo-wide conventions.
Apply this diff:
- er := fmt.Errorf("%w: failed to execute YAML function %s for key %s: %s", ErrGetKeyFailed, input, retParams.key, err) + er := fmt.Errorf(errUtils.ErrStringWrappingFormat, ErrGetKeyFailed, fmt.Sprintf("failed to execute YAML function %s for key %s: %s", input, retParams.key, err))Based on learnings.
pkg/git/git.go (4)
126-136: Unify on ErrStringWrappingFormat for error construction.Use the central format constant instead of ad-hoc literals.
Apply this diff:
- if err != nil { - return nil, fmt.Errorf("%w: failed to get local repository: %s", errUtils.ErrFailedToGetLocalRepo, err) - } + if err != nil { + return nil, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrFailedToGetLocalRepo, fmt.Sprintf("failed to get local repository: %s", err)) + } @@ - if err != nil { - return nil, fmt.Errorf("%w: failed to get repository info: %s", errUtils.ErrFailedToGetRepoInfo, err) - } + if err != nil { + return nil, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrFailedToGetRepoInfo, fmt.Sprintf("failed to get repository info: %s", err)) + }Based on learnings.
150-152: Avoid wrapping with %w when passing as %s.Since cause is only printed as a string, build it with Sprintf and drop the inner %w.
Apply this diff:
- cause := fmt.Errorf("GetRepoInfo failed for repo %s: %w", repoPath, err) - return RepoInfo{}, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrFailedToGetRepoInfo, cause) + detail := fmt.Sprintf("GetRepoInfo failed for repo %s: %s", repoPath, err) + return RepoInfo{}, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrFailedToGetRepoInfo, detail)
158-166: Standardize error formatting with the shared constant.Keeps all wrapping consistent and avoids future lint churn.
Apply this diff:
- if err != nil { - return "", fmt.Errorf("%w: failed to get local repository: %s", errUtils.ErrLocalRepoFetch, err) - } + if err != nil { + return "", fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrLocalRepoFetch, fmt.Sprintf("failed to get local repository: %s", err)) + } @@ - if err != nil { - return "", fmt.Errorf("%w: failed to get HEAD reference: %s", errUtils.ErrHeadLookup, err) - } + if err != nil { + return "", fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrHeadLookup, fmt.Sprintf("failed to get HEAD reference: %s", err)) + }Based on learnings.
171-184: Nice helper; consider a fallback open to improve robustness.Optional: if exact-path open fails, retry with DetectDotGit=true so callers can pass subdirs.
Apply this diff:
func OpenWorktreeAwareRepo(path string) (*git.Repository, error) { - // Always try with EnableDotGitCommonDir first - // This works for both regular repos and worktrees - repo, err := git.PlainOpenWithOptions(path, &git.PlainOpenOptions{ - DetectDotGit: false, // We want exact path, not parent search - EnableDotGitCommonDir: true, // Enable worktree support for config/remotes - }) - - return repo, err + // First try exact path with worktree support. + repo, err := git.PlainOpenWithOptions(path, &git.PlainOpenOptions{ + DetectDotGit: false, + EnableDotGitCommonDir: true, + }) + if err == git.ErrRepositoryNotExists { + // Fallback: allow parent search to support subdirectories. + return git.PlainOpenWithOptions(path, &git.PlainOpenOptions{ + DetectDotGit: true, + EnableDotGitCommonDir: true, + }) + } + return repo, err }pkg/utils/shell_utils.go (1)
91-94: Include the offending value for faster debugging.Add the actual ATMOS_SHLVL value to the error context.
Apply this diff:
- if err != nil { - return 0, fmt.Errorf("%w: %s", ErrConvertingShellLevel, err) - } + if err != nil { + return 0, fmt.Errorf("%w: '%s': %s", ErrConvertingShellLevel, atmosShellLvl, err) + }pkg/config/config_merge_test.go (1)
222-223: Switch to assert.ErrorIs for clarity.Swapping this to
assert.ErrorIs(t, err, errUtils.ErrMergeConfiguration)keeps the same intent with cleaner failure output and less ceremony.pkg/pro/api_client_instance_status.go (1)
19-20: Use the centralized wrapping format constant for consistency.Prefer ErrStringWrappingFormat over the literal "%w: %s" to match the rest of the PR.
As per coding guidelines.
- return fmt.Errorf("%w: %s", errUtils.ErrFailedToUploadInstanceStatus, errUtils.ErrNilRequestDTO) + return fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrFailedToUploadInstanceStatus, errUtils.ErrNilRequestDTO)internal/exec/oci_utils.go (4)
46-49: Avoid double-wrapping and add image context.pullImage already formats an error; wrapping again loses clarity and repeats context. Either (a) return the raw error from pullImage and add image context here, or (b) do the static wrap inside pullImage and return err directly here. Option (a) shown below.
As per coding guidelines.
- descriptor, err := pullImage(ref) - if err != nil { - return fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrPullImage, err) - } + descriptor, err := pullImage(ref) + if err != nil { + return fmt.Errorf("%w '%s': %s", errUtils.ErrPullImage, ref.Name(), err) + }Outside this hunk, update pullImage to stop adding its own contextual message and just return the underlying error:
// in pullImage(...) descriptor, err := remote.Get(ref, opts...) if err != nil { log.Error("Failed to pull OCI image", "image", ref.Name(), "error", err) return nil, err }
55-55: Unify wrapping format via a central constant (if available).You’re using "%w '%s': %s" here. If the repo defines a shared format (e.g., ErrIDWrappingFormat), use it for consistency; otherwise consider introducing one.
As per coding guidelines.
70-73: Prefer a central ordinal format for indexed context.The pattern "%w %d: %s" is duplicated. If you have a shared format (e.g., ErrIndexWrappingFormat = "%w [%d]: %s"), use it; otherwise consider adding one.
As per coding guidelines.
- if err := processLayer(layer, i, destDir); err != nil { - return fmt.Errorf("%w %d: %s", errUtils.ErrProcessLayer, i, err) - } + if err := processLayer(layer, i, destDir); err != nil { + return fmt.Errorf("%w %d: %s", errUtils.ErrProcessLayer, i, err) + }
25-26: Centralize ErrNoLayers in errors/errors.go and drop pkg/errors.Define a shared sentinel (e.g., errUtils.ErrNoLayers) in errors/errors.go and use it here to keep all errors centralized and avoid the pkg/errors dependency if not otherwise needed.
As per coding guidelines.
Proposed addition (errors/errors.go):
var ErrNoLayers = errors.New("the OCI image does not have any layers")Then in this file:
- var ErrNoLayers = errors.New("the OCI image does not have any layers") + // use errUtils.ErrNoLayersinternal/exec/validate_utils.go (3)
121-124: Preserve policy and use static sentinel for timeouts.Replacing the cause with errors.New loses the chain and violates the “static errors only” policy. Wrap a static timeout error and include the helpful message as context.
As per coding guidelines.
- if errors.Is(err, context.DeadlineExceeded) { - err = errors.New(timeoutErrorMessage) - } - return false, err + if errors.Is(err, context.DeadlineExceeded) { + return false, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrOPAEvaluationTimeout, timeoutErrorMessage) + } + return false, errIf ErrOPAEvaluationTimeout does not exist yet, add it to errors/errors.go:
var ErrOPAEvaluationTimeout = errors.New("OPA evaluation timeout")
211-215: Apply the same static-timeout wrapping here.Use the shared sentinel and ErrStringWrappingFormat.
As per coding guidelines.
- if err != nil { - if errors.Is(err, context.DeadlineExceeded) { - err = errors.New(timeoutErrorMessage) - } - return false, err - } + if err != nil { + if errors.Is(err, context.DeadlineExceeded) { + return false, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrOPAEvaluationTimeout, timeoutErrorMessage) + } + return false, err + }
224-228: Apply the same static-timeout wrapping on decision errors.Keep consistency across OPA timeout handling.
As per coding guidelines.
- }); err != nil { - if errors.Is(err, context.DeadlineExceeded) { - err = errors.New(timeoutErrorMessage) - } - return false, err - } + }); err != nil { + if errors.Is(err, context.DeadlineExceeded) { + return false, fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrOPAEvaluationTimeout, timeoutErrorMessage) + } + return false, err + }internal/exec/docs_generate.go (5)
121-125: Preserve underlying error from os.Stat in getTerraformSource.Include err when available; keep a no-err path for non-directory.
Apply:
- stat, err := os.Stat(joinedPath) - if err != nil || !stat.IsDir() { - return "", fmt.Errorf("%w: %s", errUtils.ErrSourceDirNotExist, joinedPath) - } + stat, err := os.Stat(joinedPath) + if err != nil { + return "", fmt.Errorf(errUtils.ErrPathStringWrappingFormat, errUtils.ErrSourceDirNotExist, joinedPath, err) + } + if !stat.IsDir() { + return "", fmt.Errorf("%w: %s", errUtils.ErrSourceDirNotExist, joinedPath) + }As per coding guidelines.
137-141: Wrap template read errors with a static error.Return a standardized error for ReadFile failures.
- body, err := os.ReadFile(templateFile) - if err != nil { - return "", err - } + body, err := os.ReadFile(templateFile) + if err != nil { + return "", fmt.Errorf(errUtils.ErrPathStringWrappingFormat, errUtils.ErrOpenFile, templateFile, err) + }Based on learnings.
299-304: Use path-aware format for resolvePath failures.This aligns with other path+error forms used in this file.
- if err != nil { - return "", "", fmt.Errorf("%w: %s", errUtils.ErrPathResolution, err) - } + if err != nil { + return "", "", fmt.Errorf(errUtils.ErrPathStringWrappingFormat, errUtils.ErrPathResolution, pathOrURL, err) + }As per coding guidelines.
306-312: Normalize temp dir errors to shared string-wrapping format.Consistent with other string-wrapped errors in this file.
- tempDir, err := os.MkdirTemp("", "atmos-docs-*") - if err != nil { - return "", "", fmt.Errorf("%w: %v", errUtils.ErrCreateTempDir, err) - } + tempDir, err := os.MkdirTemp("", "atmos-docs-*") + if err != nil { + return "", "", fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrCreateTempDir, err) + } // Ensure directory permissions are restricted. - if err := os.Chmod(tempDir, defaultDirPermissions); err != nil { - return "", "", fmt.Errorf("%w: %v", errUtils.ErrSetTempDirPermissions, err) - } + if err := os.Chmod(tempDir, defaultDirPermissions); err != nil { + return "", "", fmt.Errorf(errUtils.ErrStringWrappingFormat, errUtils.ErrSetTempDirPermissions, err) + }As per coding guidelines.
316-318: Use path+string wrapper for downloader failures.Improves consistency and discoverability with errors.Is.
- if err := downloader.NewGoGetterDownloader(atmosConfig).Fetch(pathOrURL, tempDir, downloader.ClientModeAny, 10*time.Minute); err != nil { - return "", tempDir, fmt.Errorf("%w: %s: %v", errUtils.ErrDownloadPackage, pathOrURL, err) - } + if err := downloader.NewGoGetterDownloader(atmosConfig).Fetch(pathOrURL, tempDir, downloader.ClientModeAny, 10*time.Minute); err != nil { + return "", tempDir, fmt.Errorf(errUtils.ErrPathStringWrappingFormat, errUtils.ErrDownloadPackage, pathOrURL, err) + }As per coding guidelines.
internal/exec/copy_glob.go (6)
57-59: Standardize directory creation error format.Use ErrPathWrappingFormat instead of a bespoke "for %q" phrase.
- if err := os.MkdirAll(filepath.Dir(dst), os.ModePerm); err != nil { - return fmt.Errorf("%w for %q: %s", errUtils.ErrCreateDirectory, dst, err) - } + if err := os.MkdirAll(filepath.Dir(dst), os.ModePerm); err != nil { + return fmt.Errorf(errUtils.ErrPathWrappingFormat, errUtils.ErrCreateDirectory, dst, err) + }As per coding guidelines.
67-69: Optional: add a shared “from→to” path format.Consider introducing ErrPathPairWrappingFormat = "%w from %q to %q: %s" in errors/errors.go and use it here to avoid literal duplication.
- if _, err := io.Copy(destinationFile, sourceFile); err != nil { - return fmt.Errorf("%w from %q to %q: %s", errUtils.ErrCopyFile, src, dst, err) - } + if _, err := io.Copy(destinationFile, sourceFile); err != nil { + // After adding: errUtils.ErrPathPairWrappingFormat = "%w from %q to %q: %s" + return fmt.Errorf(errUtils.ErrPathPairWrappingFormat, errUtils.ErrCopyFile, src, dst, err) + }As per coding guidelines.
75-77: Standardize permission-setting error format.Prefer ErrPathWrappingFormat for consistency.
- if err := os.Chmod(dst, info.Mode()); err != nil { - return fmt.Errorf("%w on %q: %s", errUtils.ErrSetPermissions, dst, err) - } + if err := os.Chmod(dst, info.Mode()); err != nil { + return fmt.Errorf(errUtils.ErrPathWrappingFormat, errUtils.ErrSetPermissions, dst, err) + }As per coding guidelines.
423-426: Wrap cp.Copy errors when no include/exclude patterns.Avoid returning raw cp errors; standardize with a static error.
- if len(s.IncludedPaths) == 0 && len(s.ExcludedPaths) == 0 { - log.Debug("No inclusion or exclusion patterns defined; using cp.Copy for fast copy") - return cp.Copy(sourceDir, finalTarget) - } + if len(s.IncludedPaths) == 0 && len(s.ExcludedPaths) == 0 { + log.Debug("No inclusion or exclusion patterns defined; using cp.Copy for fast copy") + if err := cp.Copy(sourceDir, finalTarget); err != nil { + return fmt.Errorf("%w from %q to %q: %s", errUtils.ErrCopyFile, sourceDir, finalTarget, err) + } + return nil + }As per coding guidelines.
380-390: Use standardized wrappers for directory creation in getLocalFinalTarget.Aligns with the rest of the file.
- if filepath.Ext(targetPath) == "" { - if err := os.MkdirAll(targetPath, os.ModePerm); err != nil { - return "", fmt.Errorf("creating target directory %q: %w", targetPath, err) - } + if filepath.Ext(targetPath) == "" { + if err := os.MkdirAll(targetPath, os.ModePerm); err != nil { + return "", fmt.Errorf(errUtils.ErrPathWrappingFormat, errUtils.ErrCreateDirectory, targetPath, err) + } return filepath.Join(targetPath, SanitizeFileName(filepath.Base(sourceDir))), nil } parent := filepath.Dir(targetPath) - if err := os.MkdirAll(parent, os.ModePerm); err != nil { - return "", fmt.Errorf("creating parent directory %q: %w", parent, err) - } + if err := os.MkdirAll(parent, os.ModePerm); err != nil { + return "", fmt.Errorf(errUtils.ErrPathWrappingFormat, errUtils.ErrCreateDirectory, parent, err) + }As per coding guidelines.
394-398: Standardize directory creation error in getNonLocalFinalTarget.Use the shared path format and error variable.
- if err := os.MkdirAll(targetPath, os.ModePerm); err != nil { - return "", fmt.Errorf("creating target directory %q: %w", targetPath, err) - } + if err := os.MkdirAll(targetPath, os.ModePerm); err != nil { + return "", fmt.Errorf(errUtils.ErrPathWrappingFormat, errUtils.ErrCreateDirectory, targetPath, err) + }As per coding guidelines.
errors/errors.go (1)
157-164: Avoid introducing a duplicate temp-directory sentinel.
ErrCreateTempDir(Line 20) already covers this failure mode. Re-declaring it here creates two distinct sentinels for the same condition, soerrors.Is(..., ErrCreateTempDir)will miss the new branch. Please alias the new name to the existing variable instead of minting anothererrors.New.- ErrCreateTempDirectory = errors.New("failed to create temp directory") + ErrCreateTempDirectory = ErrCreateTempDir

Learning: The user confirmed that the errors package has an error string wrapping format, contradicting the previous learning about ErrWrappingFormat being invalid. The current usage of fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) appears to be the correct pattern.

File: internal/exec/workflow_test.go:0-0
Timestamp: 2025-06-02T14:12:02.710Z
Learning: In the atmos codebase, workflow error handling was refactored to use `PrintErrorMarkdown` followed by returning specific error variables (like `ErrWorkflowNoSteps`, `ErrInvalidFromStep`, `ErrInvalidWorkflowStepType`, `ErrWorkflowStepFailed`) instead of `PrintErrorMarkdownAndExit`. This pattern allows proper error testing without the function terminating the process with `os.Exit`, enabling unit tests to assert on error conditions while maintaining excellent user-facing error formatting.

Learning: ErrWrappingFormat is correctly defined as "%w: %w" in the errors package and is used throughout the codebase to wrap two error types together. The usage fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) is the correct pattern when both arguments are error types.

Learning: The codebase currently uses `log.Fatal` for error handling in library functions, which terminates the program. There is a plan to refactor this approach in a separate PR to improve API design by returning error messages instead of terminating execution.

Learning: In the cloudposse/atmos Go codebase, `InitCliConfig` returns a `schema.AtmosConfiguration` value (not a pointer), while `ExecuteDescribeDependents` expects a `*schema.AtmosConfiguration` pointer parameter. Therefore, when passing the result of `InitCliConfig` to `ExecuteDescribeDependents`, use `&atmosConfig` to pass the address of the value.

pkg/config/process_yaml.go (1)
17-17: Good formatting adjustment for error messages.The change from
"%w: %v %v error %v"to"%w: %v %v error %v"standardizes the error format by adding a colon after the wrapped error. This improves error message readability and consistency.internal/tui/templates/templater.go (2)
10-10: LGTM on the new import alias.Adding the
errUtilsalias for the external errors package follows the established pattern in the codebase and provides clean access to centralized error definitions.
213-213: Excellent migration to centralized error handling.Replacing the inline
errors.New("command cannot be nil")witherrUtils.ErrCommandNilis exactly the right approach. This uses the static error definition fromerrors/errors.goas required by the coding guidelines, improving consistency and making the error testable witherrors.Is().Based on learnings
internal/exec/describe_affected_helpers.go (1)
300-305: Proper error detection using errors.Is.The change from string-based error checking to
errors.Is(err, plumbing.ErrReferenceNotFound)is a significant improvement. This approach is more reliable than checking error message contents and follows Go error handling best practices.pkg/store/errors.go (1)
8-10: Critical fix for invalid error wrapping formats.The changes from
"%w: %w"to"%w: %s"and"%w '%s': %w"to"%w '%s': %s"correctly address the original issue. Prior to Go 1.20, it was invalid to include more than one %w verb in fmt.Errorf, and even in newer versions, using multiple%wverbs only makes sense when you actually want to wrap multiple error values.The updated formats ensure only one error is wrapped (the first one) while the additional context is formatted as a string, which is the intended behavior for these error wrappers.
pkg/store/redis_store.go (1)
6-6: Import looks correct.Needed for errors.Is with redis.Nil. LGTM.
pkg/config/load.go (5)
321-322: Good switch to ErrStringWrappingFormat.Single %w wrapping with a static error is correct here.
As per coding guidelines.
332-333: Marshalling error wrapping looks correct.Uses ErrFailedMarshalConfigToYaml with a single %w as intended.
As per coding guidelines.
341-342: Correct merge error wrapping.Single %w with ErrMerge is compliant.
As per coding guidelines.
515-516: Embedded config merge wrapping is correct.Proper use of ErrMergeEmbeddedConfig with single %w.
As per coding guidelines.
373-374: Replace all two-%w usages with single-%w wrapping format.
pkg/config/load.go:373 – change

Let's uset.Skipfwith the message so we stay aligned with the test guidelines.As per coding guidelines.
87-113: Let's exercise checkArtifactType instead of skipping.
Right now every subtest is skipped, so we still have no coverage oncheckArtifactType. Please refactor the helper (e.g., accept an interface or craft a lightweight fake descriptor) so we can assert both happy and error flows.As per coding guidelines.

File: internal/exec/workflow_test.go:0-0
Timestamp: 2025-06-02T14:12:02.710Z
Learning: In the atmos codebase, workflow error handling was refactored to use `PrintErrorMarkdown` followed by returning specific error variables (like `ErrWorkflowNoSteps`, `ErrInvalidFromStep`, `ErrInvalidWorkflowStepType`, `ErrWorkflowStepFailed`) instead of `PrintErrorMarkdownAndExit`. This pattern allows proper error testing without the function terminating the process with `os.Exit`, enabling unit tests to assert on error conditions while maintaining excellent user-facing error formatting.

Learning: The codebase currently uses `log.Fatal` for error handling in library functions, which terminates the program. There is a plan to refactor this approach in a separate PR to improve API design by returning error messages instead of terminating execution.

Learning: In the atmos codebase, workflow error handling was refactored to use `PrintErrorMarkdown` followed by returning specific error variables (like `ErrWorkflowNoSteps`, `ErrInvalidFromStep`, `ErrInvalidWorkflowStepType`, `ErrWorkflowStepFailed`) instead of `PrintErrorMarkdownAndExit`. This pattern allows proper error testing without the function terminating the process with `os.Exit`, enabling unit tests to assert on error conditions while maintaining excellent user-facing error formatting.

Learning: The user confirmed that the errors package has an error string wrapping format, contradicting the previous learning about ErrWrappingFormat being invalid. The current usage of fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) appears to be the correct pattern.

This change fixes acceptance test failures across Windows, Linux, and Mac platforms by replacing the invalid error format strings with errors.Join, which properly preserves error chains for errors.Is() functionality. Changes: - Removed error format constants (ErrStringWrappingFormat, etc.) from errors/errors.go - Replaced all fmt.Errorf(errUtils.ErrStringWrappingFormat, ...) with errors.Join(...) - Fixed import conflicts between standard errors package and pkg/errors - Wrapped string arguments in fmt.Errorf when needed for errors.Join - Updated test expectations for new error message format This ensures that error chains are preserved correctly, allowing errors.Is() to work as expected throughout the codebase. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

This change refactors error handling patterns to work with the err113 linter
without requiring excessive //nolint comments, ensuring CI/CD passes.
## Changes
### Error Pattern Refactoring
- Replaced `errors.Join(staticErr, fmt.Errorf("text: %s", arg))` pattern
with `fmt.Errorf("%w: text: %s", staticErr, arg)` to satisfy err113
- Simplified `errors.Join(err1, fmt.Errorf("%v", err2))` to `errors.Join(err1, err2)`
- Fixed ~74 instances of error handling to use the approved pattern
- Added constants for repeated error format strings to satisfy revive linter
### Documentation
- Created comprehensive PRD at `docs/prd/error-handling-strategy.md`
- Updated CLAUDE.md with clear error handling patterns and examples
- Documented three distinct patterns for error handling
### Configuration
- Updated .golangci.yml with exclusion rules for legitimate patterns
- Configured linter to allow fmt.Errorf when wrapping static errors
### Results
- All err113 linter violations resolved (0 violations)
- All revive add-constant violations resolved
- Code compiles and tests pass successfully
- No //nolint comments needed
- CI/CD will pass without --no-verify workarounds
## Error Handling Patterns
1. **Combining errors**: Use `errors.Join(err1, err2)`
2. **Adding context**: Use `fmt.Errorf("%w: context: %s", staticErr, value)`
3. **Avoid**: `errors.Join(staticErr, fmt.Errorf(...))` - triggers err113

The test TestProcessConfigImportsAndReapply was failing because the error chain wasn't properly preserved when config parsing/merging failed. The test expected ErrMergeConfiguration to be in the error chain when invalid YAML is provided. Fixed by using errors.Join to wrap both ErrMergeConfiguration and the underlying error, ensuring errors.Is() can properly identify the error type while preserving the detailed error message. This maintains compatibility with the error handling patterns established in the previous refactoring while ensuring tests pass.

The usage fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) is the correct pattern when both arguments are error types.

Learning: The Atmos codebase currently uses `log.Fatal` for error handling in multiple places. The maintainers are aware this isn't an ideal pattern (should only be used in main() or init() functions) and plan to address it comprehensively in a separate PR.

Learning: The user confirmed that the errors package has an error string wrapping format, contradicting the previous learning about ErrWrappingFormat being invalid. The current usage of fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) appears to be the correct pattern.

Learning: ErrWrappingFormat is correctly defined as "%w: %w" in the errors package and is used throughout the codebase to wrap two error types together. The usage fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) is the correct pattern when both arguments are error types.

Learning: The Atmos codebase uses a consistent pattern for commands that delegate to external tools: `PersistentFlags().Bool("", false, doubleDashHint)` where doubleDashHint provides help text about using double dashes to separate Atmos options from native command arguments. This pattern is used across terraform, packer, helmfile, atlantis, aws, and ansible commands.

18-21: Good: centralized flag error format.Using a single fmt.Errorf with "%w: flag: %s" enforces one %w and consistent messages across branches. LGTM.
190-206: Pattern looks consistent across all flags.All invalid-value branches now return fmt.Errorf(errFlagFormat, ErrInvalidFlag, arg). This satisfies “wrap static first, then context.” No issues spotted.

96-98: Fix redundant timeout error message.The timeout message still includes "Timeout evaluating the OPA policy" text at the start, which duplicates the message from
errUtils.ErrOPATimeoutwhen joined on line 148. This creates redundant output like "timeout evaluating OPA policy\nTimeout evaluating the OPA policy. Please check...".Apply this diff to remove the redundant prefix:
-timeoutErrorMessage := "Timeout evaluating the OPA policy. Please check the following:\n" + +timeoutErrorMessage := "Please check the following:\n" + "1. Rego syntax\n" + "2. If 're_match' function is used and the regex pattern contains a backslash to escape special chars, the backslash itself must be escaped with another backslash"Then the
errors.Joinon line 148 will provide clean, non-redundant error context.Also applies to: 148-148

34-38: Consider initializing the default client at construction time.While the inline default client creation works, initializing
c.HTTPClientin the constructor (if nil) would avoid repeated allocation on each call. Not critical, but reduces overhead.

**/*.go: All Go comments must end with periods. Enforced by golangci-lint's godot.
Organize imports into three groups (stdlib, third-party, Atmos) separated by blank lines; sort alphabetically within each group; maintain existing aliases.
Add defer perf.Track(...) to all public functions and critical private functions, with a blank line after the call and package-prefixed name (e.g., "exec.ProcessComponent"). Use atmosConfig if available, otherwise nil.
Wrap all errors using static errors defined in errors/errors.go; never return dynamic errors directly.
Use the error wrapping pattern: fmt.Errorf("%w: details", errUtils.ErrStaticError, ...) with %w to preserve error chains and add context after the static error.
Bind environment variables with viper.BindEnv() and provide ATMOS_ alternatives for every env var (e.g., viper.BindEnv("ATMOS_GITHUB_TOKEN", "GITHUB_TOKEN")).
Ensure cross-platform compatibility: prefer SDKs over invoking binaries, use filepath.Join, os.PathSeparator/PathListSeparator, and runtime.GOOS when necessary.

Learning: The user confirmed that the errors package has an error string wrapping format, contradicting the previous learning about ErrWrappingFormat being invalid. The current usage of fmt.Errorf(errUtils.ErrWrappingFormat, errUtils.ErrAuthAwsFileManagerFailed, err) appears to be the correct pattern.
