It keeps any attribution the host environment already set (for\n    example an IDE plugin tagging agent activity through the same variable) and\n    adds the skill tag after it, so neither value clobbers the other:\n\n    ```bash\n    CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" \\\n        gcloud \u003Ccommand> [flags]\n    ```\n\n    Do not use `gcloud config set` for this: it would persist beyond the current\n    task and mislabel unrelated usage.\n\n-   **curl commands:** For direct HTTP calls (such as `curl`), you MUST pass the\n    explicit `-H \"User-Agent: ...\"` header in the shell command syntax exactly\n    like this:\n\n    ```bash\n    curl -H \"User-Agent: gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" ...\n    ```\n\n-   For client libraries, Terraform, and Cloud Storage FUSE, use the user-agent\n    options shown in the corresponding references.\n\n## Follow the Diagnostic Workflow\n\nWhenever a user requests assistance diagnosing a Cloud Storage issue:\n\n### Step 1: Clarify Context and Scope\n\n-   Clarify the exact principal (`user:{email}` or `serviceAccount:{email}`)\n    experiencing the issue.\n-   Clarify the target resource (`gs:\u002F\u002F{bucket_name}` or\n    `gs:\u002F\u002F{bucket_name}\u002F{object_path}`).\n-   Identify the attempted operation (such as read object, write object, list\n    bucket contents, or delete object).\n-   Identify the authentication mechanism (such as Signed URL, Cookieauth, OAuth\n    token, or Impersonation).\n\n### Step 2: Consult Specific Diagnostic Guide\n\n-   If the issue involves a **403 Permission Denied** error or IAM\u002FACL denial,\n    immediately consult and execute the step-by-step diagnostic procedures\n    documented in\n    [`references\u002F403_troubleshooting.md`](references\u002F403_troubleshooting.md).\n-   If running `gcloud storage buckets get-iam-policy` returns 403 Permission\n    Denied, DO NOT loop or retry inspection commands on the bucket. First verify\n    that perimeter security controls (such as VPC-SC or IP Filtering) are not\n    blocking access as detailed in `403_troubleshooting.md`, because granting\n    IAM roles will not resolve perimeter blocks. If perimeters are not the\n    cause, recognize that the diagnostic caller lacks inspection permissions\n    (`storage.buckets.getIamPolicy`). Recommend granting the least-privilege\n    role `roles\u002Fiam.securityReviewer` (or a custom role containing\n    `storage.buckets.getIamPolicy`); never recommend\n    `roles\u002Fstorage.bucketViewer` (which does not grant IAM policy access) or\n    `roles\u002Fstorage.admin`. Propose how to remediate inspection access or\n    fallback to project-level IAM policy checks as outlined in\n    `403_troubleshooting.md`.\n\n### Step 3: Propose Remediation with User Confirmation\n\n-   Synthesize your findings and explain *why* the access or operation failed\n    (such as missing IAM role, UBLA restriction, legacy ACL mismatch, or VPC-SC\n    block).\n-   Provide the exact `gcloud` remediation command.\n-   *Always include an explicit confirmation prompt (for example, \"Do you\n    approve executing this command? [Y\u002FN]\") and wait for explicit Y\u002FN\n    confirmation before executing any modification or remediation command on\n    behalf of the user.*\n\n## Phase Summary\n\n### 1. Discover Scope & Telemetry\n\n-   **Inputs:** User input (principal, bucket\u002Fobject URI, error text)\n-   **Outputs:** Target scope, UBLA vs ACL classification\n-   **Reference Section:** `references\u002F403_troubleshooting.md` Steps 1-2\n\n### 2. Telemetry & Policy Eval\n\n-   **Inputs:**\n    `CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT\n    }gcs-skills...\" gcloud storage buckets describe \u002F get-iam-policy`\n-   **Outputs:** Active IAM roles, VPC-SC alerts, Deny policies\n-   **Reference Section:** `references\u002F403_troubleshooting.md` Steps 3-7\n\n### 3. Edge-Case Root Cause Isolation\n\n-   **Inputs:** Advanced signals (`requesterPays`, `retentionPeriod`, ADC)\n-   **Outputs:** Root cause diagnosis\n-   **Reference Section:** `references\u002F403_troubleshooting.md` Step 8\n\n### 4. Prescriptive Remediation\n\n-   **Inputs:** Root cause diagnosis\n-   **Outputs:** Tagged `gcloud` remediation command + Y\u002FN prompt\n-   **Reference Section:** `Apply Attribution Tags` section & Step 8\n\n## Error Handling Matrix\n\nThe following list provides common Cloud Storage 403 scenarios and the\nprescriptive response you MUST give. Use this exactly.\n\n### `Permission 'storage.buckets.getIamPolicy' denied`\n\n-   **Cause:** Diagnostic caller lacks `storage.buckets.getIamPolicy` permission\n    (such as missing `roles\u002Fiam.securityReviewer`), or request is blocked by\n    perimeter security controls (VPC-SC \u002F IP Filtering).\n-   **Fix:** **DO NOT LOOP OR RETRY.** First check whether perimeter security\n    controls (such as VPC-SC or IP Filtering) are blocking access; do not\n    blindly prescribe role grants when perimeters are involved. If perimeters\n    are not the cause, explain that the account executing the check lacks bucket\n    IAM inspection permissions. Recommend granting the least-privilege role\n    `roles\u002Fiam.securityReviewer` or a custom role containing\n    `storage.buckets.getIamPolicy` (never `roles\u002Fstorage.bucketViewer` or\n    `roles\u002Fstorage.admin`).\n\n### `Bucket is requester pays bucket but no user project provided`\n\n-   **Cause:** `requesterPays: true` enabled on target bucket\n-   **Fix:** **DO NOT LOOP OR RETRY.** Even with full `objectViewer` roles,\n    requests must pass billing project. Prescribe `--billing-project=PROJECT_ID`\n    or `-u PROJECT_ID`.\n\n### `Request is prohibited by organization's policy. vpcServiceControlsUniqueIdentifier`\n\n-   **Cause:** Request blocked by VPC Service Controls (VPC-SC) service\n    perimeter\n-   **Fix:** Inform user that adding IAM roles cannot bypass a VPC-SC perimeter.\n    Direct user to Organization\u002FProject Administrator to update ingress\u002Fegress\n    rules.\n\n### `Request is prohibited by organization's policy.` (No VPC-SC ID)\n\n-   **Cause:** Organization Policy constraint (such as\n    `constraints\u002Fstorage.publicAccessPrevention` or\n    `constraints\u002Fgcp.resourceLocations`) or a VPC-SC perimeter block without a\n    logged UUID\n-   **Fix:** Inspect active Organization Policy constraints (`gcloud\n    org-policies list --project=PROJECT_ID`) or check Cloud Audit Logs for\n    perimeter rejections, and direct the user to the Organization\u002FProject\n    Administrator.\n\n### `Permission '...' denied ... due to an IAM deny policy` (or `403` despite `roles\u002Fstorage.admin` allow bindings)\n\n-   **Cause:** Organization, Folder, or Project IAM Deny policy\n    (`iam.googleapis.com\u002FDenyPolicy`) explicitly denies the permission\n-   **Fix:** Explain that explicit IAM Deny policies take absolute precedence\n    over standard allow roles (including `roles\u002Fstorage.admin`) and cannot be\n    bypassed. Advise checking Deny policies (`gcloud iam policies list\n    --attachment-point=cloudresourcemanager.googleapis.com\u002Fprojects\u002FPROJECT_ID\n    --kind=denypolicies`, and `--attachment-point=organizations\u002FORG_ID` if\n    needed) and contacting the Organization Administrator.\n\n### `403 Insufficient Permission` on a Compute Engine VM despite correct IAM roles\n\n-   **Cause:** Legacy GCE VM Access Scopes (`devstorage.read_only`) restrict\n    OAuth token scopes\n-   **Fix:** **DO NOT RUN LIVE INSPECTION COMMANDS ON FICTIONAL VMS.** Explain\n    immediately that GCE access scopes throttle OAuth tokens regardless of IAM\n    roles. Advise stopping the VM (`gcloud compute instances stop INSTANCE`),\n    setting scopes to `cloud-platform` (`gcloud compute instances\n    set-service-account INSTANCE --scopes=cloud-platform`), and restarting the\n    VM (`gcloud compute instances start INSTANCE`).\n\n### `403 Permission Denied` on object delete despite `roles\u002Fstorage.admin`\n\n-   **Cause:** Bucket has an active Retention Policy (`retention_policy`)\n-   **Fix:** Explain that retention locks act as un-bypassable data protection\n    holds and cannot be overridden by IAM until the retention timestamp expires.\n\n### `403 Permission Denied` on recreated Service Account with exact same email\n\n-   **Cause:** Account deleted and recreated generates a new underlying Unique\n    ID\n-   **Fix:** Instruct user to remove the old IAM policy binding and re-add the\n    exact same binding so IAM registers the new Unique ID.\n\n### `403 Permission Denied` due to Bucket IP Filter\n\n-   **Cause:** The bucket has `ip_filter_config` configured with `mode:\n    \"Enabled\"`, blocking the caller's IP address and preventing live metadata\n    checks.\n-   **Fix:** Route diagnostic queries through Cloud Audit Logs to confirm the IP\n    filter violation:\n\n    ```bash\n    CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" \\\n        gcloud logging read \"resource.type=gcs_bucket AND resource.labels.bucket_name=\\\"{bucket_name}\\\" AND protoPayload.authenticationInfo.principalEmail=\\\"{principal_email}\\\"\" --project=\"{project_id}\" --limit=5 --format=json\n    ```\n\n    If `gcloud logging read` returns permission errors (`403`), `Project not\n    found or deleted`, an empty array `[]`, or only unrelated Admin Activity\n    entries (`cloudaudit.googleapis.com%2Factivity`) with zero Data Access\n    entries (`cloudaudit.googleapis.com%2Fdata_access`) for the failing\n    operation, do not loop or retry. Immediately halt technical diagnosis,\n    inform the user that they lack visibility into the Cloud Audit Logs (due to\n    permissions, disabled Data Access logging, or log exclusions) and cannot\n    definitively diagnose advanced network denials, suggest that Bucket-Level IP\n    Filtering or VPC Service Controls may be blocking access, and direct them to\n    ask a Project\u002FOrganization Administrator to check the Cloud Audit Logs\n    (including `protoPayload.status.code=7` and\n    `vpcServiceControlsUniqueIdentifier`) or enable Data Access Audit Logs.\n\n    **Remediation:** Do not write ad-hoc CLI commands. Refer to Step 8 in\n    `references\u002F403_troubleshooting.md` for proper instructions to fetch the\n    existing `ip_filter_config`, append the caller's CIDR to\n    `allowedIpCidrRanges` in `ALLOWED_IPS.json` without overwriting existing\n    ranges, and apply it via the `gcloud storage buckets update` command.\n\n### `403 Permission Denied` on `storage.cloud.google.com` in Browser (Cookieauth)\n\n-   **Cause:** Browser downloads via the `storage.cloud.google.com` domain use\n    Google Account cookie authentication, also known as `Cookieauth`. Having\n    Data Access Audit Logging (`DATA_READ` \u002F `DATA_WRITE` for\n    `storage.googleapis.com`) enabled on the project conflicts with Cookieauth\n    and causes consistent 403 errors in the browser (or multiple logged-in\n    Google Accounts send the wrong identity cookie).\n-   **Fix:** Inspect the bucket IAM policy\u002Fconfiguration and check the project's\n    audit log configuration using:\n\n    ```bash\n    CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" \\\n        gcloud projects get-iam-policy {project_id} --format=\"json(auditConfigs)\"\n    ```\n\n    Explain that Data Access Logging conflicts with Cookieauth when accessing\n    objects via `storage.cloud.google.com` in the browser. Advise accessing\n    objects via `gcloud`, API endpoints (`storage.googleapis.com`), or Signed\n    URLs to bypass browser cookie authentication limitations (or testing in an\n    Incognito window \u002F adjusting Data Access Audit Logging if browser access is\n    required).\n\n### `404 Not Found` or `Bucket does not exist`\n\n-   **Cause:** Target bucket does not exist or was deleted\n-   **Fix:** **DO NOT LOOP OR RETRY.** Stop trying to execute live commands on\n    the missing bucket. Acknowledge the bucket is missing, but proceed to\n    explain your diagnosis hypothetically based on the provided scenario\n    context.\n","# Cloud Storage Diagnostic\n\n> [!CAUTION]\n>\n> **CRITICAL SAFETY MANDATE: NO AUTO-EXECUTION OF REMEDIATION COMMANDS**\n>\n> **NEVER execute any state-modifying, configuration-changing, or remediation\n> commands** (such as `gcloud storage buckets add-iam-policy-binding`, `gcloud\n> storage buckets update`, ACL modifications, or object\u002Fbucket updates)\n> **autonomously or without prior user approval.**\n>\n> **RATIONALE & BLAST RADIUS**: Cloud Storage security configurations (IAM\n> policy bindings, bucket IP filters, UBLA settings, retention policies) carry\n> an extremely high blast radius.

Use this exactly.\n\n### `Permission 'storage.buckets.getIamPolicy' denied`\n\n-   **Cause:** Diagnostic caller lacks `storage.buckets.getIamPolicy` permission\n    (such as missing `roles\u002Fiam.securityReviewer`), or request is blocked by\n    perimeter security controls (VPC-SC \u002F IP Filtering).\n-   **Fix:** **DO NOT LOOP OR RETRY.** First check whether perimeter security\n    controls (such as VPC-SC or IP Filtering) are blocking access; do not\n    blindly prescribe role grants when perimeters are involved. If perimeters\n    are not the cause, explain that the account executing the check lacks bucket\n    IAM inspection permissions. Recommend granting the least-privilege role\n    `roles\u002Fiam.securityReviewer` or a custom role containing\n    `storage.buckets.getIamPolicy` (never `roles\u002Fstorage.bucketViewer` or\n    `roles\u002Fstorage.admin`).\n\n### `Bucket is requester pays bucket but no user project provided`\n\n-   **Cause:** `requesterPays: true` enabled on target bucket\n-   **Fix:** **DO NOT LOOP OR RETRY.** Even with full `objectViewer` roles,\n    requests must pass billing project. Prescribe `--billing-project=PROJECT_ID`\n    or `-u PROJECT_ID`.\n\n### `Request is prohibited by organization's policy. vpcServiceControlsUniqueIdentifier`\n\n-   **Cause:** Request blocked by VPC Service Controls (VPC-SC) service\n    perimeter\n-   **Fix:** Inform user that adding IAM roles cannot bypass a VPC-SC perimeter.\n    Direct user to Organization\u002FProject Administrator to update ingress\u002Fegress\n    rules.\n\n### `Request is prohibited by organization's policy.` (No VPC-SC ID)\n\n-   **Cause:** Organization Policy constraint (such as\n    `constraints\u002Fstorage.publicAccessPrevention` or\n    `constraints\u002Fgcp.resourceLocations`) or a VPC-SC perimeter block without a\n    logged UUID\n-   **Fix:** Inspect active Organization Policy constraints (`gcloud\n    org-policies list --project=PROJECT_ID`) or check Cloud Audit Logs for\n    perimeter rejections, and direct the user to the Organization\u002FProject\n    Administrator.\n\n### `Permission '...' denied ... due to an IAM deny policy` (or `403` despite `roles\u002Fstorage.admin` allow bindings)\n\n-   **Cause:** Organization, Folder, or Project IAM Deny policy\n    (`iam.googleapis.com\u002FDenyPolicy`) explicitly denies the permission\n-   **Fix:** Explain that explicit IAM Deny policies take absolute precedence\n    over standard allow roles (including `roles\u002Fstorage.admin`) and cannot be\n    bypassed. Advise checking Deny policies (`gcloud iam policies list\n    --attachment-point=cloudresourcemanager.googleapis.com\u002Fprojects\u002FPROJECT_ID\n    --kind=denypolicies`, and `--attachment-point=organizations\u002FORG_ID` if\n    needed) and contacting the Organization Administrator.\n\n### `403 Insufficient Permission` on a Compute Engine VM despite correct IAM roles\n\n-   **Cause:** Legacy GCE VM Access Scopes (`devstorage.read_only`) restrict\n    OAuth token scopes\n-   **Fix:** **DO NOT RUN LIVE INSPECTION COMMANDS ON FICTIONAL VMS.** Explain\n    immediately that GCE access scopes throttle OAuth tokens regardless of IAM\n    roles. Advise stopping the VM (`gcloud compute instances stop INSTANCE`),\n    setting scopes to `cloud-platform` (`gcloud compute instances\n    set-service-account INSTANCE --scopes=cloud-platform`), and restarting the\n    VM (`gcloud compute instances start INSTANCE`).\n\n### `403 Permission Denied` on object delete despite `roles\u002Fstorage.admin`\n\n-   **Cause:** Bucket has an active Retention Policy (`retention_policy`)\n-   **Fix:** Explain that retention locks act as un-bypassable data protection\n    holds and cannot be overridden by IAM until the retention timestamp expires.\n\n### `403 Permission Denied` on recreated Service Account with exact same email\n\n-   **Cause:** Account deleted and recreated generates a new underlying Unique\n    ID\n-   **Fix:** Instruct user to remove the old IAM policy binding and re-add the\n    exact same binding so IAM registers the new Unique ID.\n\n### `403 Permission Denied` due to Bucket IP Filter\n\n-   **Cause:** The bucket has `ip_filter_config` configured with `mode:\n    \"Enabled\"`, blocking the caller's IP address and preventing live metadata\n    checks.\n-   **Fix:** Route diagnostic queries through Cloud Audit Logs to confirm the IP\n    filter violation:\n\n    ```bash\n    CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" \\\n        gcloud logging read \"resource.type=gcs_bucket AND resource.labels.bucket_name=\\\"{bucket_name}\\\" AND protoPayload.authenticationInfo.principalEmail=\\\"{principal_email}\\\"\" --project=\"{project_id}\" --limit=5 --format=json\n    ```\n\n    If `gcloud logging read` returns permission errors (`403`), `Project not\n    found or deleted`, an empty array `[]`, or only unrelated Admin Activity\n    entries (`cloudaudit.googleapis.com%2Factivity`) with zero Data Access\n    entries (`cloudaudit.googleapis.com%2Fdata_access`) for the failing\n    operation, do not loop or retry. Immediately halt technical diagnosis,\n    inform the user that they lack visibility into the Cloud Audit Logs (due to\n    permissions, disabled Data Access logging, or log exclusions) and cannot\n    definitively diagnose advanced network denials, suggest that Bucket-Level IP\n    Filtering or VPC Service Controls may be blocking access, and direct them to\n    ask a Project\u002FOrganization Administrator to check the Cloud Audit Logs\n    (including `protoPayload.status.code=7` and\n    `vpcServiceControlsUniqueIdentifier`) or enable Data Access Audit Logs.\n\n    **Remediation:** Do not write ad-hoc CLI commands. Refer to Step 8 in\n    `references\u002F403_troubleshooting.md` for proper instructions to fetch the\n    existing `ip_filter_config`, append the caller's CIDR to\n    `allowedIpCidrRanges` in `ALLOWED_IPS.json` without overwriting existing\n    ranges, and apply it via the `gcloud storage buckets update` command.\n\n### `403 Permission Denied` on `storage.cloud.google.com` in Browser (Cookieauth)\n\n-   **Cause:** Browser downloads via the `storage.cloud.google.com` domain use\n    Google Account cookie authentication, also known as `Cookieauth`. Having\n    Data Access Audit Logging (`DATA_READ` \u002F `DATA_WRITE` for\n    `storage.googleapis.com`) enabled on the project conflicts with Cookieauth\n    and causes consistent 403 errors in the browser (or multiple logged-in\n    Google Accounts send the wrong identity cookie).\n-   **Fix:** Inspect the bucket IAM policy\u002Fconfiguration and check the project's\n    audit log configuration using:\n\n    ```bash\n    CLOUDSDK_METRICS_ENVIRONMENT=\"${CLOUDSDK_METRICS_ENVIRONMENT:+$CLOUDSDK_METRICS_ENVIRONMENT }gcs-skills gcs-skills\u002F1.0 (skill:google-cloud-storage-diagnostic)\" \\\n        gcloud projects get-iam-policy {project_id} --format=\"json(auditConfigs)\"\n    ```\n\n    Explain that Data Access Logging conflicts with Cookieauth when accessing\n    objects via `storage.cloud.google.com` in the browser. Advise accessing\n    objects via `gcloud`, API endpoints (`storage.googleapis.com`), or Signed\n    URLs to bypass browser cookie authentication limitations (or testing in an\n    Incognito window \u002F adjusting Data Access Audit Logging if browser access is\n    required).\n\n### `404 Not Found` or `Bucket does not exist`\n\n-   **Cause:** Target bucket does not exist or was deleted\n-   **Fix:** **DO NOT LOOP OR RETRY.** Stop trying to execute live commands on\n    the missing bucket. Acknowledge the bucket is missing, but proceed to\n    explain your diagnosis hypothetically based on the provided scenario\n    context.\n",{"name":5,"license":15,"metadata":52,"description":7},{"tags":53,"version":54,"category":55,"publisher":9,"support_tier":56},"gcs, storage, troubleshooting, diagnostic, iam, 403, permissions","1.0.1","Storage","primary","main","cd6fde0b299b34bbad05f64ad1ed5bd2ed05e634","skills\u002Fcloud\u002Fgoogle-cloud-storage-diagnostic",2005,"https:\u002F\u002Fgithub.com\u002Fgoogle\u002Fskills","https:\u002F\u002Fgithub.com\u002Fgoogle","https:\u002F\u002Fopensource.google\u002F","Google ❤️ Open Source","2026-11-14 01:51:35",{"source":8,"skillName":5,"commands":67,"prompt":77,"zipAvailable":78},[68,71,74],{"tool":69,"command":70},"npx","npx skills add google\u002Fskills --skill google-cloud-storage-diagnostic",{"tool":72,"command":73},"bunx","bunx skills add google\u002Fskills --skill google-cloud-storage-diagnostic",{"tool":75,"command":76},"pnpm","pnpm dlx skills add google\u002Fskills --skill google-cloud-storage-diagnostic","安装技能，技能地址：https:\u002F\u002Fgithub.com\u002Fgoogle\u002Fskills\u002Fblob\u002Fmain\u002Fskills\u002Fcloud\u002Fgoogle-cloud-storage-diagnostic\u002FSKILL.md",true,[80],{"path":81,"resourceType":82,"resourceTypeDesc":83,"sizeBytes":84,"sourceHtmlUrl":85},"references\u002F403_troubleshooting.md","REFERENCE","参考文档",25719,"https:\u002F\u002Fgithub.com\u002Fgoogle\u002Fskills\u002Fblob\u002Fmain\u002Fskills\u002Fcloud\u002Fgoogle-cloud-storage-diagnostic\u002Freferences\u002F403_troubleshooting.md",[87,121,152,181,207,231],{"skillNo":88,"name":89,"nameZh":6,"description":90,"descriptionZh":6,"repositoryFullName":8,"ownerLogin":9,"ownerAvatarUrl":10,"ownerAccountNo":11,"ownerDisplayName":12,"repositoryNo":13,"starsCount":14,"licenseSpdxId":15,"licenseFileUrl":6,"sourceHtmlUrl":91,"categories":92,"keywords":101,"publishedAt":47},"01M6998S2EZKD3GEJ7F943RZTE","sign-in-with-google-web","Implement, configure, and secure Sign In With Google (SiwG) using Google Identity Services (GIS \u002F `https:\u002F\u002Faccounts.google.com\u002Fgsi\u002Fclient`) across web architectures.
