# Developer Hooks and Filters

Use the hooks implemented in the installed release and keep output factual. This reference covers a small verified set rather than hypothetical integration names.

Verified Free hooks
-------------------

HookPurpose`citelayer_llmstxt_content`Filter generated llms text; receives content and is\_full`citelayer_llmstxt_enhancement_block`Filter the enhancement block lines`citelayer_llms_txt_max_posts`Limit listed posts per type`citelayer_organization_schema`Filter Organization output`citelayer_person_schema`Filter Person output`citelayer_website_schema`Filter WebSite output`citelayer_article_schema`Filter Article data; receives schema and post`citelayer_bot_analytics_cleanup_days`Set local log retention`citelayer_ability_called`Observe ability execution through the audit actionExample: change retention deliberately
--------------------------------------

```
add_filter( 'citelayer_bot_analytics_cleanup_days', function ( $days ) {
    return 30;
} );
```

Put custom integration code in your own plugin. Test on a separate environment before production. A lower retention window makes older activity unavailable; it is not a correction to a score.

Integration verification
------------------------

1. Match the hook signature in your installed release source.
2. Return the expected type and sanitize custom input.
3. Test generator and public output, including cached reads and SEO enhancement mode.
4. Check the relevant Woo/EDD route contract separately; do not assume add-ons expose the same hooks.

Current source reference
