Boilerplate Update Skill

Update WordPress plugins to the latest plugin-boilerplate features.

User Confirmation Rules

ASK for confirmation before:

• Replacing or significantly restructuring files (Loader.php, main plugin class)

• Changing build tools or asset pipeline

• Modifying CI/CD workflows

• Adding new architectural patterns (Abilities API, Blocks)

• Deleting resources belonging to plugin features

Proceed without confirmation for:

• Updating dependency versions

• Adding/renaming scripts with equivalent functionality

• Syncing QA config files

• Copying .opencode commands and .agents/skills

Identity Replacement Script

Use scripts/boilerplate-replace.php (bundled with this skill) for deterministic placeholder replacement. This avoids manual AI search-and-replace across copied upstream files.

Determine the target plugin identity

Before running the script, read these sources from the target plugin to determine the three required parameters:

• plugin-name — Plugin Name: header in the main plugin PHP file (the root .php file containing @wordpress-plugin headers)

• plugin-text-domain — Text Domain: header in the same file

• plugin-namespace — the PSR-4 namespace mapped to src/ in composer.json (autoload.psr-4 ), or the namespace declaration in src/*.php files

Apply replacements on the cloned boilerplate

Run the script against the cloned boilerplate directory so every file in the reference copy already carries the target plugin's identity before you compare or copy anything:

php tmp/boilerplate-ref/.agents/skills/boilerplate-update/scripts/boilerplate-replace.php
--path tmp/boilerplate-ref
--plugin-name "My Awesome Plugin"
--plugin-namespace "My_Awesome_Plugin"
--plugin-text-domain "my-awesome-plugin"
--cleanup-setup

This does three things in one pass:

• Replaces all boilerplate placeholders (demo-plugin , Demo_Plugin , etc.)

• Strips all BOILERPLATE-DOCS marker sections

• Removes setup-only artifacts (setup.php , src/Cli/Setup.php , composer autoload/hook entries)

After this step every diff between tmp/boilerplate-ref/ and the target plugin shows only real upstream changes -- no placeholder noise and no setup-only files.

Workflow

• Clone fresh boilerplate for comparison: git clone --depth 1 https://github.com/JUVOJustin/wordpress-plugin-boilerplate.git ./tmp/boilerplate-ref

• Determine target plugin identity (see above).

• Run the replacement script on tmp/boilerplate-ref with --cleanup-setup (see above).

• Use one subtask/subagent per key area. Delegate comparison using diff against tmp/boilerplate-ref/ .

• Present findings to user, categorized by confirmation requirement.

• Apply changes incrementally.

• Cleanup: rm -rf tmp/boilerplate-ref

• add_shortcode($tag, $component, $callback)

• add_cli($name, $instance, $args)

• add_ability($ability_class)

• Categories auto-register

• register_blocks()

• See tmp/boilerplate-ref/docs/create-blocks.mdx

6. i18n Workflow

Scripts: i18n:extract (creates .pot, updates .po) and i18n:compile (generates .mo, .json, .php)

See tmp/boilerplate-ref/docs/i18n.mdx for workflow, caveats, and AI command.

7. Abilities API (WordPress 6.9+)

See tmp/boilerplate-ref/docs/abilities.mdx for interface reference and examples.

Key pattern: $this->loader->add_ability(Abilities\My_Ability::class)

8. Agent Configuration

Compare:

• diff -r .opencode/command tmp/boilerplate-ref/.opencode/command

• diff -r .agents/skills tmp/boilerplate-ref/.agents/skills

See tmp/boilerplate-ref/docs/work-with-ai.mdx for AI integration details.

Sync strategy:

• Add new items from upstream

• Update existing (ask user if diff is significant)

• Ask user before removing local-only items

• Adapt text domain and paths after copying

• Remove redundant skills/commands if upstream now includes them or they are possibly renamed

9. File Control files

Compare:

• diff .distignore tmp/boilerplate-ref/.distignore

• diff .gitignore tmp/boilerplate-ref/.gitignore

Verification

• Ran composer install && npm install after changes

• Ran npm run build after changes

• Ran composer phpstan && composer phpcs after changes

• Ran npm run lint:js && npm run lint:style after changes

• Test plugin functionality
