…manifest The stacks/stack-config/1.0.json copy of aws_cloudformation_component_manifest was missing "secrets" (present alongside settings/hooks for every other component type, and already present in the atmos/manifest/1.0.json copy), so a component-level `secrets:` block on an aws/cloudformation component was rejected by the schema atmos validate/describe stacks enforce by default. Extended the existing drift-guard fixture to exercise the field. Found via CodeRabbit review. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…ommands Execute's switch already handles "destroy" (alias of delete) and "outputs" (alias of output), but GetAvailableCommands omitted both, so consumers that gate on the returned list (e.g. pkg/composition/executor.go's verb-support check) rejected those two valid aliases even though Execute itself accepts them. Found via CodeRabbit review. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…d error ErrAwsCloudFormationComponentArgRequired's message said the component argument is only optional with --all or --affected, but validateOperationArgs also accepts --tags/--labels as valid selection flags. Updated the message and its test expectations to match. Found via CodeRabbit review. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
SupportedFormats and the terraform output --format flag help text both advertise "table" for single-key output (e.g. atmos terraform output <component> <key> --format=table), and validateOutputFormat accepted it, but singleValueFormatters had no FormatTable entry, so dispatchSingleValueFormat's own "unsupported format" error listed table as a supported format while actually rejecting it. Added a single-value table formatter that renders a one-row styled table via the existing formatTable renderer. Found via CodeRabbit review. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The doc claimed the aws/cloudformation YAML key must be quoted because it contains a slash. Standard YAML does not treat "/" as a special character, so quoting is a readability choice, not a requirement. Found via CodeRabbit review. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…detection fix The component-type path-misdetection fix (this branch, prior commit) correctly stops treating the bare components/terraform base directory as if it resolved to a packer component. Regenerate the snapshot this session's own coverage-fix bug fix made stale -- the new message is factually accurate (no component resolves at all), where the old one wrongly claimed a packer-component match.
…e apply post-deploy gating
Two real-AWS field-test bugs, both rooted in Phase 1's core lifecycle code:
1. newS3Backend (packaging.go) only wired identity-based S3 credentials when
info.Identity was a non-empty *explicit* per-component override. The
standard, documented default-identity pattern (auth.identities.<name>.
default: true, no explicit identity: field) left info.Identity empty, so
the upload silently fell through to the bare ambient AWS SDK credential
chain instead of the identity already working for every other call in the
same command - failing with "no EC2 IMDS role found" against real AWS.
activeIdentityName() now falls back to info.AuthContext.AWS.Profile, the
same signal the CloudFormation client itself already trusts. Also fixed a
second, independent bug in the same function: it called s3store.NewStore
directly instead of the registry's artifact.NewBackend, so opts.Resolver
was never actually wired into the store even for the explicit-identity
case, and opts.Type used the wrong registry key ("s3" instead of "aws/s3").
2. runApply (executor.go) unconditionally ran setStackPolicy/
applyTerminationProtection/describeStackOutputs after deliverApply
returned, regardless of whether a direct stack deploy actually happened.
For a publish-only `--target <aws/s3 target>` delivery (deliverApply
returns result == nil - no stack ever created), these stack-scoped calls
always crashed with a raw AWS "Stack does not exist" error unrelated to
what the user asked for. runApply now returns immediately when
result == nil. Also added wrapAPICallError (changeset.go), a narrowly
scoped helper that recognizes this "does not exist" AWS error shape and
adds an explanation + hint via the error builder, applied at the three
call sites most directly implicated (setStackPolicy, applyTermination
Protection, describeStackOutputs) - every other AWS error still falls
through to the existing plain sentinel wrap unchanged.

…at the repo root components."aws/cloudformation".base_path is a brand-new field this stack introduces: existing atmos.yaml files never set it, and defaultCliConfig's own default only applies via mergeDefaultConfig when no config file is found at all. AtmosConfigAbsolutePaths joined atmosBasePathAbs with the raw (possibly empty) BasePath with no empty-string fallback, so CloudFormationDirAbsolutePath silently collapsed to the bare project root instead of the documented default "components/cloudformation" - confirmed live against a real external repo that had never configured this section, producing a confusing "no such file or directory" instead of working out of the box. Mirrors the identical defensive-default fix already applied a few lines above for Components.Container.BasePath. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…tion base_path default 352c77d defaulted components."aws/cloudformation".base_path to "components/cloudformation" whenever it's unset, but didn't regenerate the golden snapshots that dump the merged config. Fourteen TestCLICommands snapshots (describe config/configuration/component, indentation, secrets-masking, --chdir isolation) still asserted the old empty base_path and repo-root cloudFormationDirAbsolutePath, so CI's acceptance-test shards failed across linux/macos. Regenerated via -regenerate-snapshots; the only diffs are the aws/cloudformation base_path and cloudFormationDirAbsolutePath lines matching the new default.

119-119: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winDrop CloudFormation from the custom-component-types sentence.
Line 115 now lists CloudFormation as a native component type. Line 119 still offers it as an example of a tool you would wrap with a custom component type: "AWS CDK, CloudFormation, Pulumi, Bicep, database migrations". This PR removed CloudFormation from exactly that list in
website/docs/components/custom.mdx, so the two pages now disagree.📝 Proposed fix
-Beyond the native types, you can define **[custom component types](/components/custom)** to manage any tool—AWS CDK, CloudFormation, Pulumi, Bicep, database migrations, and more—with the same stack-based configuration. +Beyond the native types, you can define **[custom component types](/components/custom)** to manage any tool—AWS CDK, Pulumi, Bicep, database migrations, and more—with the same stack-based configuration.🤖 Prompt for AI Agents

assert the second call returns zero events while preserving successful error
handling.
In `@pkg/component/aws/cloudformation/executor_bulk.go`:
- Line 57: Update the bulk CloudFormation execution call to pass ctx.GoContext()
instead of context.Background() into executeGraph, preserving caller
cancellation and deadlines through ExecuteGraph and provider operations.
In `@pkg/component/aws/cloudformation/executor.go`:
- Around line 229-230: Update the summary count in the render-diff flow to count
only changes with non-nil ResourceChange values, matching the entries displayed
by the loop. Adjust TestRenderDiffSummary_ListsResourceChanges to expect the
filtered resource-change count.
- Around line 104-108: Update resolveSpecAndTemplate to build stackSpec before
resolving or provisioning the component path, and return it immediately for
OperationDelete and OperationOutput. Ensure provisionAndResolveComponentPath is
only called for operations that require local files, and add tests verifying
both delete and output bypass it even when provisioning would fail.
- Around line 353-358: Change renderOutputsSummary to return an error: propagate
formatter failures instead of reporting them through ui.Error, and return any
error from data.Write. Update both runOutput and runApply to handle and
propagate the error so output-generation failures are reported as unsuccessful.
In `@pkg/component/aws/cloudformation/packaging.go`:
- Line 66: Update uploadPackage to wrap the backend-construction error before
returning it, including the relevant bucket or target name while preserving the
original error with %w. Keep the existing successful path unchanged.
In `@pkg/component/aws/cloudformation/provision.go`:
- Around line 55-57: Update the CloudFormation provisioning flow in provision.go
at lines 55-57 and 79-79: package oversized templates before direct deployment,
use the resulting URL as TemplateURL in the deployDirect path, and pass the same
packaged reference to the external target artifact instead of the original
template body. Use the existing packaging result consistently across both
delivery paths.
In `@pkg/datafetcher/schema/stacks/stack-config/1.0.json`:
- Around line 1036-1064: Update the aws_cloudformation type-defaults
definition’s properties to include auth, dependencies, source, and provision
alongside vars, env, settings, and hooks, using the corresponding existing
schema references. Keep additionalProperties set to false and align the allowed
properties with the aws_cloudformation definition in the manifest schema.
In `@pkg/hooks/event.go`:
- Around line 54-61: Update HookEvent.Normalize and the lifecycle event
selection around eventsFor so CloudFormation plan hooks execute through the
existing diff events and deploy hooks through the existing apply events, while
preserving any intended original CLI verb behavior. Add coverage for both plan
and deploy mappings in the hook tests.
In `@pkg/vendor/uri.go`:
- Around line 118-120: Update IsArchiveURI to classify sources using go-getter’s
parsed source, subdirectory, and archive option instead of stripping the query
and checking the full URI. Honor archive directives so archive=true and
archive=false override extension-based detection, and correctly handle archive
paths with nested subdirectories. Add regression tests covering ?archive=zip,
.zip?archive=false, and .zip//nested.
In `@website/docs/cli/commands/aws/cloudformation/apply.mdx`:
- Around line 57-58: Update the --stack descriptions in
website/docs/cli/commands/aws/cloudformation/apply.mdx lines 57-58,
website/docs/cli/commands/aws/cloudformation/delete.mdx lines 60-61, and
website/docs/cli/commands/aws/cloudformation/deploy.mdx lines 38-39 to state the
actual requirement: --stack is required only for single-component commands if
that matches the CLI; otherwise add --stack to every --all or --affected
example. Keep the CLI and website documentation consistent.
In `@website/docs/cli/commands/aws/cloudformation/validate.mdx`:
- Line 36: Update the Flags section for the cloudformation validate command to
document the --base option used in the example, using the canonical CLI help
text and keeping the website documentation synchronized with the CLI.
---
Outside diff comments:
In `@pkg/hooks/command_engine.go`:
- Line 744: Update resolveProvisionedWorkdir to include
cfg.CloudFormationComponentType in the provisioned component-type cases, and add
a ComponentPath regression test verifying CloudFormation uses the existing
provisioned workdir rather than the in-repository path.
In `@website/docs/components/components-overview.mdx`:
- Line 119: Update the custom component types sentence near “custom component
types” to remove CloudFormation from its example list, keeping AWS CDK, Pulumi,
Bicep, database migrations, and the surrounding wording unchanged.
---
Nitpick comments:
In `@cmd/aws/cloudformation/cloudformation_test.go`:
- Around line 220-231: Update the test table’s wantErr field to hold error
values and replace substring-based assertions with require.ErrorIs using
errUtils.ErrAwsCloudFormationFlagsMutuallyExclusive,
errUtils.ErrAwsCloudFormationComponentArgRequired, and
errUtils.ErrAwsCloudFormationComponentArgWithSelection for the corresponding
cases. Retain ErrorContains only for the --labels parse case when
tags.ParseLabelsFlag has no exported sentinel.
In `@internal/exec/describe_affected_changed_files_index.go`:
- Around line 200-201: Add atmosConfig.Components.CloudFormation.BasePath to
buildNormalizedBasePaths, using the same empty-path guard as the other component
base paths, so the CloudFormation lookup in the cfg.CloudFormationComponentType
case resolves the indexed path instead of falling back to allFiles.
In `@pkg/component/aws/cloudformation/delete_test.go`:
- Line 17: Refactor TestDeleteStack_BlocksOnTerminationProtection and the other
deleteStack scenario tests into one table-driven test covering all five
scenarios. Define per-case mock setup callbacks and expected outcomes so shared
controller and client initialization is performed once while preserving each
scenario’s behavior.
In `@pkg/component/aws/cloudformation/executor_bulk.go`:
- Line 182: Update the assignments receiving results from
executeAffectedWithRepoPath so they do not use more than three blank
identifiers, preserving the affected and error values; if four discarded results
are unavoidable, add a narrowly scoped nolint:dogsled comment that explains the
reason.
In `@pkg/component/aws/cloudformation/parameters_test.go`:
- Around line 38-46: Convert TestIsTruthy in
pkg/component/aws/cloudformation/parameters_test.go (lines 38-46) and
TestIsArchiveURI in pkg/vendor/uri_test.go (lines 410-423) to table-driven tests
with named cases executed via t.Run, preserving each existing input and expected
result.
In `@pkg/output/format_test.go`:
- Around line 984-996: Replace the manual search in findSubstringIndex with
strings.Index while preserving the existing startIdx boundary behavior and
return value semantics. Remove the dead idx computation and the _ = idx
statement, and add the required strings import.
In `@pkg/output/output.go`:
- Around line 115-122: Update WriteToFile to wrap both OpenFile and WriteString
errors with contextual messages that include filePath, using fmt.Errorf with %w
and adding the fmt import; preserve the existing file handling and return
behavior.
In `@pkg/provisioner/source/vendor.go`:
- Line 471: Update the single-entry check around entries and copySingleFile to
require entries[0].Type().IsRegular() rather than only excluding directories,
while preserving the existing directory-copy path for non-regular entries such
as symlinks to directories.
In `@pkg/terraform/output/format_test.go`:
- Around line 43-46: Update
TestFormatSingleValueWithOptions_DelegatesToSharedOutput to pass a non-default
FormatOptions value, such as Flatten: true, so the assertion verifies that
FormatSingleValueWithOptions forwards opts to the shared formatter.
In `@pkg/terraform/output/output_test.go`:
- Around line 29-36: Add a TestFormatConstants_MatchSharedOutput test alongside
TestWriteToFile_DelegatesToSharedOutput that asserts every re-exported format
constant and slice matches its corresponding sharedoutput value, including
DefaultFlattenSeparator; import the shared output package under the existing
alias convention.

Fixes 15 functional/quality issues CodeRabbit's review of PR #2999 raised, plus documentation gaps and missing screengrab casts: - changeset.go: bound the generated change-set name to CloudFormation's 128-character ChangeSetName limit (a maximum-length stack name previously produced a name AWS would reject). - delete.go: restore termination protection when a delete request fails after --disable-termination-protection cleared it, so a failed delete doesn't silently leave a previously-protected stack unprotected. Also extracted guardTerminationProtection/guardRetainResources/ handleDeleteStackError to bring deleteStack back under the complexity budget. - executor.go: resolveSpecAndTemplate no longer provisions local files (JIT source checkout) for delete/output, which need only spec.StackName; renderDiffSummary's header count now matches the resource-change lines it actually prints; renderOutputsSummary now returns (and both callers propagate) formatter/write failures instead of silently succeeding with no output. - executor_bulk.go: pass ctx.GoContext() into ExecuteGraph instead of a disconnected context.Background(), so bulk runs honor caller cancellation. - packaging.go: wrap the S3 backend-construction error with the bucket name. - provision.go/changeset.go/spec.go: package an oversized template before a *direct* deploy too (not just external-target delivery) and send it via the new stackSpec.TemplateURL/CreateChangeSet's TemplateURL, since AWS rejects a TemplateBody over the inline limit; external-target delivery now sends the packaged reference instead of re-embedding the original oversized body. - internal/exec: addCloudFormationSectionAffected now compares section presence on both sides, not just local presence, so a section removed locally but still present on the remote ref is detected as affected. - pkg/hooks/event.go: Normalize maps aws/cloudformation's plan/deploy CLI verb aliases to the diff/apply events the executor actually emits, so hooks configured for "before.aws/cloudformation.plan"/"...deploy" fire. - pkg/vendor/uri.go: IsArchiveURI now honors go-getter's `archive` query parameter override in both directions and strips a `//subdir` suffix before checking the source's own extension. - Regenerated the 9 missing aws/cloudformation screengrab casts referenced by demo/casts/atmos.d/screengrabs/cli.yaml. - Docs: clarified --stack is required only for single-component commands (not with --all/--affected) across all 8 aws/cloudformation command pages; documented --base where used in examples; added a language identifier to a fenced code block flagged by markdownlint. Also extracted shared gomock expectation-chain test helpers (expectRunApplySuccessfulDeployFlow, expectDescribeStacksWithVpcIDOutput) to resolve dupl findings introduced by the new render-error regression tests, and fixed a lint finding on the new changeSetName truncation logic.

…e query param as bool CodeRabbit review findings on PR #2999: - pkg/component/aws/cloudformation/packaging.go: packageURL interpolated the object key straight into a virtual-hosted-style https:// URL with no escaping, so keys containing spaces, "#", "?", etc. could produce a URL that fails or silently points at the wrong object (e.g. an unescaped "#" truncates the path at a URL fragment). It also always used virtual-hosted-style addressing, which breaks TLS certificate validation for bucket names containing dots (the wildcard cert for *.s3.<region>.amazonaws.com covers exactly one label). packageURL now builds the URL via net/url so the key is percent-escaped per path segment while "/" separators are preserved, and switches to regional path-style addressing (bucket in the path, not the host) specifically for dotted bucket names, keeping virtual-hosted-style for the common case per AWS's own guidance. - pkg/vendor/uri.go: IsArchiveURI only recognized the literal string "false" as disabling the `archive` query param override, so go-getter's own boolean-false spellings ("0", "f", "F", "FALSE", "False") were misclassified as forcing unarchiving instead of disabling it -- go-getter v1.8.6's client.go parses this value with strconv.ParseBool. IsArchiveURI now does the same, extracted into a small archiveQueryOverride helper to keep nesting complexity down; a value ParseBool can't parse at all (e.g. an explicit archive type like "zip") still forces unarchiving as before. Added regression tests: dotted-bucket path-style addressing, non-dotted bucket virtual-hosted-style (unchanged), key-escaping under both addressing styles, and archive=0/archive=f/archive=FALSE/archive=1/archive=t/archive=tar.

…compressors lookup
go-getter's client.go rewrites a ParseBool-false archive= value to the
sentinel "-" but leaves a ParseBool-true value ("true"/"1"/"t") as that
literal string -- neither is ever a Decompressors map key, so go-getter
downloads the source as a plain file either way instead of extracting it.
IsArchiveURI previously treated any ParseBool-true value as forcing
unarchiving, diverging from go-getter's actual behavior. It now returns
false for boolean-true-like values and for any non-boolean value that
isn't one of go-getter's real directory-archive Decompressors keys (zip,
tar, tar.gz, ...), matching the single-file codec keys (bz2, gz, xz, zst)
and unsupported types the same way.
