## Description

Creator Assistant Knowledge is an add-on for [Creator Assistant – Hub](https://wordpress.org/plugins/creator-assistant-hub/)
that lets you maintain a private, admin-only knowledge base. Entries are vectorized
and stored in your Qdrant cluster so the AI can draw on them when answering search
queries — without ever exposing them to site visitors.

**Your existing posts and pages are never modified.** The plugin creates a new private
post type (`ca_knowledge`) and creates draft entries when visitors give negative
feedback on an AI answer. No public content is touched.

**Key features**

 * **Private knowledge base** — a dedicated `Knowledge` section appears in the WordPress
   admin where you can write private articles, FAQs, and reference material for 
   the AI. These entries are completely invisible to visitors: they have no public
   URL, do not appear in search results, and are never linked from the frontend.
 * **Automatic indexing into a private collection** – knowledge entries are vectorized
   by Creator Assistant Hub whenever they are published or updated, into a Qdrant
   collection this plugin owns (`creator_assistant_knowledge_chunk`) rather than
   the shared one. Nothing else on the site can read them: only the AI Overview 
   answer does.
 * **Feedback loop** — when a visitor reports that an AI Overview answer did not
   help (or a search query receives no answer at all), the plugin automatically 
   creates a draft knowledge entry pre-filled with the query and the AI response.
   Admins can review and improve these drafts, then publish them so the AI learns
   from the gap.
 * **No duplicate drafts** – before creating one, the plugin compares the query 
   with the searches already assigned to existing entries. The same question asked
   in different words is added to the entry that already covers it instead of producing
   a second draft, and the entry counts one more request. How similar two searches
   have to be is a setting.
 * **Sorted by demand** – the entry list shows how many times each gap was asked
   for, and the column sorts, so you can answer the questions people actually ask
   first.
 * **Origin at a glance** – the entry list also shows why each draft exists: a negative
   rating, an unanswered search, or written by hand, so you know which entries came
   from a real gap before you open them.
 * **Sources shown only to editors** – knowledge entries contribute to the AI answer,
   and the AI Overview panel lists them as sources only for users who can edit them,
   linking to the edit screen. A visitor never sees them: a source with no public
   URL would be a dead link, and the knowledge base stays invisible end-to-end.

**Requirements**

 * [Creator Assistant – Hub](https://wordpress.org/plugins/creator-assistant-hub/)
   installed, activated, and configured.
 * [Creator Assistant Search](https://wordpress.org/plugins/creator-assistant-search/)(
   for the feedback feature).
 * WordPress 6.6 or higher.
 * PHP 7.4 or higher.

### External services

This plugin relies on **Creator Assistant – Hub** for its connections to OpenAI 
and Qdrant; see the Hub’s own “External services” section for full details on that
data flow. This plugin’s own use of those services:

 * **OpenAI**: knowledge base entries are sent to the Embeddings API (via the Hub)
   whenever they are published or updated, to generate the vector used to index 
   them and to match visitor searches against private entries.
    - Service: [https://platform.openai.com/](https://platform.openai.com/)
    - Privacy Policy: [https://openai.com/policies/privacy-policy](https://openai.com/policies/privacy-policy)
    - Terms of Use: [https://openai.com/policies/terms-of-use](https://openai.com/policies/terms-of-use)
 * **Qdrant Cloud**: knowledge entry vectors are stored in two collections this 
   plugin owns (`creator_assistant_<id>_knowledge_chunk` and `creator_assistant_
   <id>_knowledge_intent`, where `<id>` is the random identifier Creator Assistant
   Hub gives each site so several sites can share one Qdrant cluster), separate 
   from the Hub’s shared collection so nothing else can read them.
    - Service: [https://cloud.qdrant.io/](https://cloud.qdrant.io/)
    - Privacy Policy: [https://qdrant.tech/legal/privacy-policy/](https://qdrant.tech/legal/privacy-policy/)
    - Terms of Service: [https://qdrant.tech/legal/terms_and_conditions/](https://qdrant.tech/legal/terms_and_conditions/)

Data is only transmitted once you have configured Creator Assistant – Hub with your
own API credentials and accepted its Terms of Service. Nothing is transmitted automatically
upon activation of this plugin.

### Development

The plugin ships no compiled assets: `assets/js/feedback.js`, `assets/js/editor-
panel.js` and `assets/css/feedback.css` are hand-written and need no build step.
Only the PHP development tooling has to be installed to work on it.

    ```
    composer install installs PHPCS with the WordPress and VIP standards, PHPStan and PHPUnit. Then:
    ```

 * `npm run lint:php` runs PHPCS, `npm run fix:php` applies the automatic fixes.
 * `npm run analyse:php` runs PHPStan, which also scans the Hub and Search sibling
   plugins because their classes are used throughout.
 * `npm test` runs the unit tests. They use hand-written WordPress stubs and load
   neither WordPress, a database, nor the Hub.
 * `npm run check` runs the WordPress.org Plugin Check CLI.

## Installation

 1. Make sure **Creator Assistant – Hub** and **Creator Assistant Search** are installed
    and configured.
 2. Upload the `creator-assistant-knowledge` folder to the `/wp-content/plugins/` directory.
 3. Activate the plugin through the **Plugins** screen in WordPress.
 4. A **Knowledge** menu item appears in the WordPress admin. Create and publish entries
    there; they will be vectorized automatically.

## FAQ

### Will knowledge entries appear on my site?

No. The `ca_knowledge` post type is registered as strictly private:

 * `publicly_queryable: false` — direct URL requests return a 404.
 * `exclude_from_search: true` — entries never appear in WordPress search results.
 * `has_archive: false` — no archive page exists.
 * `rewrite: false` — no pretty permalink is generated.

There is no way for a visitor to access or discover knowledge entries from the frontend.

### Does the plugin modify my existing posts or pages?

No. Creator Assistant Knowledge only creates new entries in its own private post
type. Your existing posts, pages, custom post types, and all their content are completely
untouched.

### There is no way to say the answer was good. Why?

Because nothing would be done with it. This plugin acts on gaps: what it can do 
with “this did not help” is open a draft entry for an admin to answer. A button 
that records nothing would be a control that lies about what it does, so there is
only one, and it reports a problem.

### When a visitor reports an answer, does that create a public post?

No. The plugin creates a **draft** entry of the private `ca_knowledge` post type.
Drafts are never publicly visible. The entry is pre-filled with the search query
and the AI response so an admin can review it, improve it, and publish it to the
knowledge base — at which point it becomes available to the AI but remains invisible
to visitors (see above).

### Does every report create a new draft?

No. Before creating a draft the plugin embeds the query and compares it with the
searches already assigned to existing entries, published or draft. Above a similarity
threshold the query is recorded on the entry that already covers it and no new draft
is created, so a gap asked in ten different wordings produces one entry with ten
recorded searches instead of ten drafts. The searches assigned to an entry are listed
in a panel in the editor sidebar, and the entry list shows how many wordings and
how many requests each entry has collected.

### How do I change how aggressively drafts are merged?

Creator Assistant, then Knowledge. The similarity threshold is the only setting 
there, and the page explains what the numbers mean.

The whole range is usable. At 1 nothing is ever merged and every new wording gets
its own entry. At 0 everything is merged: after the first entry, no new one is created
and every unanswered search is filed under it. In between, raise it and you get 
a second draft for a question you already have, which you can see and merge by hand;
lower it and a distinct question ends up filed under an entry that does not answer
it, and nobody notices. The two mistakes do not cost the same, so when in doubt,
raise it.

### Why does the AI Overview panel not appear on my classic theme when only knowledge entries match?

Because there is nothing for the results loop to render. Knowledge entries are private,
so they are never put into the search results, and on a classic theme the panel 
is injected on `loop_start`, which WordPress does not fire when the loop is empty.
Block themes are unaffected: the panel is injected around the query block, which
renders either way.

If your site runs a classic theme and you want the panel on those searches too, 
place it explicitly with the `[creator_assistant_search_ai_overview]` shortcode 
or the AI Overview block in your search template, instead of relying on automatic
insertion.

### What does the plugin write to my database?

Two things:

 1. **`ca_knowledge` posts** — entries you create in the Knowledge admin section, plus
    any drafts created automatically from visitor feedback. All are private and never
    visible on the frontend.
 2. A **post meta entry** (`_creator_assistant_knowledge_reason`) on feedback-generated
    drafts, recording whether the draft was created because of a negative rating (`
    negative_feedback`) or an unanswered query (`no_answer`).
 3. **Post meta entries** (`_creator_assistant_knowledge_queries`), one per search 
    assigned to an entry, so the admin can see which wordings that entry has to cover.
 4. A **post meta entry** (`_creator_assistant_knowledge_hits`) counting how many times
    an entry was asked for.
 5. One **option** (`creator_assistant_knowledge_intent_threshold`), the similarity
    threshold from the settings page.

No existing post content, meta, status, or taxonomy data is ever modified.

### What happens if I deactivate or delete the plugin?

**Deactivating** the plugin hides the Knowledge admin section and stops feedback
processing; your knowledge entries are preserved in the database.

**Deleting** the plugin removes all knowledge entries and their post meta from your
WordPress database, and drops the two Qdrant collections it owns (`creator_assistant_
<id>_knowledge_chunk` and `creator_assistant_<id>_knowledge_intent`, where `<id>`
is the random identifier Creator Assistant Hub gives each site so several sites 
can share one Qdrant cluster). Your regular posts, pages, all public content and
the shared vector collections are completely unaffected.

### What happens to the deduplication data if I reset the Hub or change its embedding model?

Creator Assistant – Hub’s Reset button, and switching to a different embedding model,
both invalidate every stored query vector: the whole point of the similarity comparison
is that queries embedded with different models are not comparable. When either happens,
this plugin drops its query-matching collection (`creator_assistant_knowledge_intent`)
and rebuilds it in the background, in small batches, from the searches already assigned
to your entries. Nothing you have written is lost: the entries, their assigned searches
and their request counts all stay as they were, only the vectors used to recognise
a reworded question are recomputed.

## Changelog

#### 1.0.0

 * Initial release.

   help, and the endpoint behind it.
 * Automatic draft creation for negative feedback and unanswered queries, with semantic
   deduplication of similar queries and a configurable similarity threshold.
