Fix Bootstrap Params

by UI52b8c4a944e39No licenseListed Oct 8, 2026Updated Oct 8, 2026

Fix HTML bootstrap parameter issues that UI5 linter reports but cannot auto-fix. Use this skill when linter outputs these rules: - `no-deprecated-api` - For missing/deprecated bootstrap parameters (async, compat-version, animation, binding-syntax, etc.) - `no-deprecated-theme` - For deprecated theme values in data-sap-ui-theme - `no-deprecated-library` - For deprecated libraries in data-sap-ui-libs Trigger on error messages containing: "Missing bootstrap parameter", "Abandoned bootstrap parameter", "Redundant bootstrap parameter", "deprecated value", "bootstrap" Automatically applies safe fixes to HTML files containing UI5 bootstrap script tags.

AI-generated overview

Fixes UI5 HTML bootstrap script parameters flagged by the UI5 linter but not auto-fixable.

What it does
This skill edits the UI5 bootstrap script tag in HTML files to resolve linter findings that cannot be auto-fixed. It adds missing parameters such as data-sap-ui-async and data-sap-ui-compat-version, updates deprecated values, removes abandoned or redundant parameters, replaces deprecated themes with sap_horizon variants, and strips deprecated libraries from data-sap-ui-libs. It preserves formatting and leaves all non-bootstrap script tags untouched.
When to use it
Use it when UI5 linter output reports no-deprecated-api, no-deprecated-theme, or no-deprecated-library issues on HTML bootstrap parameters. It is intended for messages such as missing, abandoned, redundant, or deprecated bootstrap parameters and deprecated theme or library values.
Requirements
No scripts are shipped; it is instructions only. It requires the agent to read and write HTML files and to have the UI5 linter output identifying the affected rules and messages.

Fix Bootstrap Parameters

Key Rules

  1. ONLY modify the bootstrap <script> tag (identified by id="sap-ui-bootstrap" or src matching sap-ui-core.js). All other <script> tags — including inline scripts, config blocks, and non-UI5 script references — MUST be preserved exactly as-is. They will be handled by fix-csp-compliance in a later phase.
  2. Do not delete, move, or rewrite any <script> block that is not the bootstrap tag. If the file has <script>window.config = {...}</script> before or after the bootstrap tag, leave it untouched.

This skill fixes HTML bootstrap parameter issues that the UI5 linter detects but cannot auto-fix because the changes may affect application behavior.

no-deprecated-libraryUse of deprecated library '...'Remove from libs

When to Use

Apply this skill when you see linter output like:

index.html:8:3 error Missing bootstrap parameter 'data-sap-ui-async'  no-deprecated-apiindex.html:9:3 error Missing bootstrap parameter 'data-sap-ui-compat-version'  no-deprecated-apiindex.html:12:3 error Abandoned bootstrap parameter 'data-sap-ui-no-duplicate-ids' should be removed  no-deprecated-apiindex.html:15:3 error Use of deprecated theme 'sap_bluecrystal'  no-deprecated-theme

Fix Strategy

1. Locate the Bootstrap Script Tag

Find the <script> tag with either:

  • id="sap-ui-bootstrap"
  • src attribute matching pattern: sap-ui-core.js, sap-ui-custom.js, sap-ui-boot.js, etc.

2. Apply Fixes Based on Rule and Message

no-deprecated-api - Missing Parameters

Missing data-sap-ui-async: Add data-sap-ui-async="true" Missing data-sap-ui-compat-version: Add data-sap-ui-compat-version="edge"

html
<!-- Before --><script id="sap-ui-bootstrap"    src="resources/sap-ui-core.js"    data-sap-ui-theme="sap_horizon"></script>
<!-- After --><script id="sap-ui-bootstrap"    src="resources/sap-ui-core.js"    data-sap-ui-async="true"    data-sap-ui-compat-version="edge"    data-sap-ui-theme="sap_horizon"></script>
no-deprecated-api - Deprecated Values

data-sap-ui-async="false": Change to "true" data-sap-ui-compat-version with non-edge value: Change to "edge"

no-deprecated-api - Abandoned Parameters (remove completely)

Remove these parameters entirely:

  • data-sap-ui-no-duplicate-ids - Enforced in modern UI5
  • data-sap-ui-auto-aria-body-role - Removed in modern UI5
  • data-sap-ui-manifest-first - Use Component.create manifest option instead
  • data-sap-ui-origin-info - No longer supported
  • data-sap-ui-areas - Use Control.placeAt instead
  • data-sap-ui-trace - No longer supported
  • data-sap-ui-xx-no-less - No longer supported
no-deprecated-api - Redundant Parameters
  • data-sap-ui-binding-syntax="simple" - Remove; complex syntax is enforced in modern UI5
  • data-sap-ui-binding-syntax="complex" - Remove if compat-version="edge" is set
  • data-sap-ui-preload with invalid values - Remove
no-deprecated-api - Replaced Parameters
  • data-sap-ui-animation → data-sap-ui-animation-mode (convert true→full, false→minimal)
no-deprecated-theme - Deprecated Themes

Replace with modern theme:

  • sap_bluecrystal → sap_horizon
  • sap_belize → sap_horizon
  • sap_belize_plus → sap_horizon
  • sap_belize_hcb → sap_horizon_hcb
  • sap_belize_hcw → sap_horizon_hcw
  • sap_hcb → sap_horizon_hcb
  • sap_ux → sap_horizon
  • sap_platinum → sap_horizon
  • sap_goldreflection → sap_horizon
no-deprecated-library - Deprecated Libraries

Remove deprecated libraries from data-sap-ui-libs:

  • sap.ui.commons
  • sap.ui.ux3
  • sap.makit
  • sap.me
  • sap.ca.ui
  • sap.sac.grid
  • sap.ui.suite
  • sap.zen.commons
  • sap.zen.crosstab
  • sap.zen.dsh

Implementation Steps

  1. Read the HTML file
  2. Parse to find the bootstrap script tag
  3. For each linter error (identified by rule ID and message):
    • If missing parameter: Add the parameter with recommended value
    • If deprecated value: Update to recommended value
    • If abandoned/redundant: Remove the parameter
    • If deprecated theme: Replace with modern theme
    • If deprecated library: Remove from libs list
  4. Preserve formatting (indentation, line breaks) as much as possible
  5. Write the updated file

Example Fix

Given linter output:

index.html:8:3 error Missing bootstrap parameter 'data-sap-ui-async'  no-deprecated-apiindex.html:8:3 error Missing bootstrap parameter 'data-sap-ui-compat-version'  no-deprecated-apiindex.html:12:3 error Abandoned bootstrap parameter 'data-sap-ui-no-duplicate-ids' should be removed  no-deprecated-apiindex.html:10:3 error Use of deprecated theme 'sap_bluecrystal'  no-deprecated-theme

Transform:

html
<!-- Before --><script id="sap-ui-bootstrap"    src="resources/sap-ui-core.js"    data-sap-ui-theme="sap_bluecrystal"    data-sap-ui-no-duplicate-ids="true"    data-sap-ui-resource-roots='{"my.app": "./"}'></script>
<!-- After --><script id="sap-ui-bootstrap"    src="resources/sap-ui-core.js"    data-sap-ui-async="true"    data-sap-ui-compat-version="edge"    data-sap-ui-theme="sap_horizon"    data-sap-ui-resource-roots='{"my.app": "./"}'></script>

Notes

  • Always add data-sap-ui-async="true" before other data attributes for consistency
  • Setting compat-version="edge" enables complex binding syntax automatically, so binding-syntax becomes redundant
  • Removed parameters should not leave trailing whitespace or empty lines
  • If the file has multiple script tags, only modify the bootstrap tag — leave all others intact (including inline <script> blocks that will be handled by CSP compliance in Phase 5)
