# bDS — Remaining Feature Work
|
|
|
|
This document covers the features described in VISION.md that are not yet
|
|
implemented. Each section is a self-contained plan that can be picked up
|
|
independently.
|
|
|
|
---
|
|
|
|
## ~~1. Template Editor & Per-Entity Template Selection~~ ✅ Done
|
|
|
|
### Goal
|
|
|
|
Users can create, edit, and manage Liquid templates inside the application.
|
|
Categories, tags, and individual posts can select which template to use for
|
|
rendering. The bundled templates serve as defaults; user templates override them.
|
|
|
|
### Current State
|
|
|
|
- Liquid templates are bundled in `src/main/engine/templates/` (3 templates +
|
|
partials + macros).
|
|
- `PageRenderer` resolves templates from fixed directory roots.
|
|
- No user-editable templates, no template CRUD, no per-entity template
|
|
selection.
|
|
- The `ScriptEngine` + `ScriptsView` combination already implements the exact
|
|
pattern needed (file-based storage with YAML metadata, Monaco editor, CRUD,
|
|
database index, file sync).
|
|
|
|
### Implementation Plan
|
|
|
|
#### 1.1 Database Schema
|
|
|
|
Add a `templates` table to `schema.ts`:
|
|
|
|
| Column | Type | Notes |
|
|
|-------------|---------|----------------------------------------------|
|
|
| id | text PK | UUID |
|
|
| projectId | text FK | References projects |
|
|
| slug | text | Unique per project |
|
|
| title | text | Display name |
|
|
| kind | text | `'post'`, `'list'`, `'not-found'`, `'partial'` |
|
|
| filePath | text | Relative path within project `templates/` dir |
|
|
| enabled | integer | 0/1 — disabled templates fall back to built-in |
|
|
| version | integer | Incremented on each save |
|
|
| createdAt | integer | Timestamp |
|
|
| updatedAt | integer | Timestamp |
|
|
|
|
Add template selection fields:
|
|
|
|
- `CategoryMetadata`: add optional `postTemplateSlug` and `listTemplateSlug`
|
|
fields (stored in `meta/project.json`).
|
|
- Posts table: add optional `templateSlug` column for per-post overrides.
|
|
- Tags table: add optional `postTemplateSlug` column for tag-level overrides.
|
|
|
|
#### 1.2 Engine Class — `TemplateEngine`
|
|
|
|
Follow the `ScriptEngine` pattern exactly:
|
|
|
|
- `createTemplate(input)` — write `.liquid` file with YAML frontmatter +
|
|
database entry.
|
|
- `updateTemplate(id, updates)` — update file + database, increment version.
|
|
- `deleteTemplate(id)` — remove file + database entry.
|
|
- `getTemplate(id)` / `getAllTemplates()` — read from database, load content
|
|
from file.
|
|
- `rebuildDatabaseFromFiles()` — scan `templates/` directory, rebuild database
|
|
from file metadata.
|
|
- `reconcileTemplatesFromGitChanges()` — sync database after git operations.
|
|
- `validateTemplate(content)` — attempt Liquid parse, return errors.
|
|
|
|
Store templates as `.liquid` files in the project's `templates/` directory with
|
|
YAML frontmatter:
|
|
|
|
```liquid
|
|
---
|
|
id: <uuid>
|
|
projectId: <uuid>
|
|
slug: custom-post
|
|
title: Custom Post Layout
|
|
kind: post
|
|
enabled: true
|
|
version: 3
|
|
---
|
|
<main>
|
|
<article>{{ post.content | markdown }}</article>
|
|
</main>
|
|
```
|
|
|
|
#### 1.3 Template Resolution in PageRenderer
|
|
|
|
Modify `PageRenderer` to resolve templates with priority:
|
|
|
|
1. Post-specific template override (`posts.templateSlug`)
|
|
2. Tag-level template override (first matching tag with a `postTemplateSlug`)
|
|
3. Category-level template override (`CategoryMetadata.postTemplateSlug`)
|
|
4. Built-in default template
|
|
|
|
Add the project's `templates/` directory to `resolvePageRendererTemplateRoots()`
|
|
so Liquid's `{% render %}` can find user partials.
|
|
|
|
#### 1.4 IPC Handlers
|
|
|
|
Register in `handlers.ts`:
|
|
|
|
- `templates:create`, `templates:update`, `templates:delete`
|
|
- `templates:get`, `templates:getAll`
|
|
- `templates:validate`
|
|
|
|
Expose in `preload.ts` and update `electronApi.ts` types.
|
|
|
|
#### 1.5 UI — `TemplateEditorView`
|
|
|
|
Mirror `ScriptsView`:
|
|
|
|
- Sidebar activity: add "Templates" icon to ActivityBar.
|
|
- Sidebar list: show all templates grouped by kind, with enabled/disabled
|
|
state.
|
|
- Tab content: Monaco editor with `liquid` or `html` language mode.
|
|
- Metadata fields: title, slug, kind dropdown, enabled toggle.
|
|
- Actions: save (Ctrl+S), validate syntax, delete.
|
|
- Footer: created/updated timestamps.
|
|
|
|
#### 1.6 Template Assignment UI
|
|
|
|
In `SettingsView`, extend the category metadata section:
|
|
|
|
- Add "Post Template" and "List Template" dropdowns per category, populated
|
|
from user templates of matching kind.
|
|
|
|
In the post editor metadata area:
|
|
|
|
- Add optional "Template Override" dropdown (only shows user templates of kind
|
|
`post`).
|
|
|
|
#### 1.7 Starter Templates
|
|
|
|
On project creation, copy the bundled templates into the project's `templates/`
|
|
directory so users have a working starting point they can modify.
|
|
|
|

|
|
|
## 2. Post Translation System
|
|
|
|
### Goal
|
|
|
|
Posts have a language attribute. The AI importing agent detects post language
|
|
and can auto-translate posts. Posts link to their translations so the
|
|
publishing pipeline can generate multilingual output.
|
|
|
|
### Current State
|
|
|
|
- Posts have no `language` field.
|
|
- No translation relationship tracking.
|
|
- No language detection during import.
|
|
- No AI translation tools.
|
|
- The `excerpt` field already exists and can serve as the summary field
|
|
mentioned in the vision.
|
|
- `analyzeMediaImage()` in `OpenCodeManager` already demonstrates the pattern
|
|
for single-shot AI analysis with language parameters.
|
|
- Project-level `mainLanguage` exists in `MetaEngine`.
|
|
|
|
### Implementation Plan
|
|
|
|
#### 2.1 Database Schema
|
|
|
|
Extend the `posts` table:
|
|
|
|
| Column | Type | Notes |
|
|
|-----------------|------|-------------------------------------------------|
|
|
| language | text | ISO code (`en`, `de`, etc.), defaults to project `mainLanguage` |
|
|
| translationOfId | text | FK to posts.id — the original post this is a translation of |
|
|
|
|
No separate junction table needed. A translated post is simply a post with
|
|
`translationOfId` pointing at its source. This keeps the model simple: each
|
|
post belongs to exactly one language and optionally references one original.
|
|
|
|
#### 2.2 YAML Frontmatter
|
|
|
|
Extend `postFileUtils.ts` to read/write:
|
|
|
|
```yaml
|
|
language: de
|
|
translationOf: <original-post-id>
|
|
```
|
|
|
|
On `readPostFile()`, parse these fields. On `writePostFile()`, include them
|
|
when present.
|
|
|
|
#### 2.3 PostEngine Extensions
|
|
|
|
Add methods:
|
|
|
|
- `getTranslations(postId)` — find all posts where `translationOfId === postId`.
|
|
- `getOriginal(postId)` — if the post has `translationOfId`, return that post.
|
|
- `createTranslation(originalPostId, targetLanguage, content)` — create a new
|
|
post linked to the original with the target language set.
|
|
|
|
Modify `createPost()` and `updatePost()` to accept and persist the `language`
|
|
and `translationOfId` fields.
|
|
|
|
#### 2.4 AI Translation Tools in OpenCodeManager
|
|
|
|
Add three new methods following the `analyzeMediaImage()` pattern:
|
|
|
|
**`detectPostLanguage(postId)`**
|
|
- Read post content.
|
|
- Send to AI with prompt: "Detect the language of this text. Return a JSON
|
|
object with `language` (ISO 639-1 code) and `confidence` (0-1)."
|
|
- Return `{ language: string, confidence: number }`.
|
|
|
|
**`translatePost(postId, targetLanguage)`**
|
|
- Read full post content + title + excerpt.
|
|
- Send to AI with prompt: "Translate this blog post to {language}. Return JSON
|
|
with `title`, `content` (markdown), and `excerpt`."
|
|
- Return translated fields without creating a post (caller decides).
|
|
|
|
**`generatePostSummary(postId)`**
|
|
- Read post content.
|
|
- Send to AI: "Write a 2-3 sentence summary of this blog post in
|
|
{post.language}. Return JSON with `excerpt`."
|
|
- Return `{ excerpt: string }`.
|
|
|
|
Register these as IPC handlers: `chat:detectPostLanguage`,
|
|
`chat:translatePost`, `chat:generatePostSummary`.
|
|
|
|
#### 2.5 Import Pipeline Integration
|
|
|
|
In `ImportExecutionEngine`, after a post is imported and published:
|
|
|
|
1. Call `detectPostLanguage()` to set the `language` field.
|
|
2. If the detected language differs from the project's `mainLanguage`, queue
|
|
a translation task via `TaskManager`.
|
|
3. The translation task calls `translatePost()`, creates a new post via
|
|
`createTranslation()`, and publishes it.
|
|
|
|
This is optional and should be configurable per import definition (a checkbox
|
|
"Auto-detect language and translate" in `ImportAnalysisView`).
|
|
|
|
#### 2.6 UI — Translation Panel
|
|
|
|
In the post editor metadata area, add a "Translations" section:
|
|
|
|
- Show current post language (dropdown to change).
|
|
- List existing translations with links (open in new tab).
|
|
- "Translate to..." button that opens a language picker, triggers AI
|
|
translation, and creates the linked post.
|
|
- If the post is itself a translation, show "Original: {title}" link.
|
|
|
|
In the sidebar post list, optionally show a language badge per post.
|
|
|
|
#### 2.7 Publishing Pipeline
|
|
|
|
In `PageRenderer` and `BlogGenerationEngine`:
|
|
|
|
- Add `hreflang` link tags to generated HTML when translations exist.
|
|
- Optionally generate a language switcher partial that templates can include.
|
|
- Sitemap should include `xhtml:link` entries for alternate language versions.
|

## 3. MCP Server — Agent-Assisted Content Creation - done
|
|
|
|
### Goal
|
|
|
|
Host an MCP (Model Context Protocol) server inside the application so external
|
|
AI agents (Claude Code, Cursor, etc.) can connect and work with bDS. The core
|
|
principle: **read access is open, write access goes through user-reviewable
|
|
drafts**. External agents never silently mutate data — they propose changes
|
|
that the user accepts or discards inside the agent's UI.
|
|
|
|
This enables powerful workflows: an agent can read existing posts, draft a new
|
|
one with pre-filled content, propose a Python script or Liquid template, or
|
|
suggest image metadata improvements — and the user always has final say before
|
|
anything enters the system.
|
|
|
|
### Current State
|
|
|
|
- `OpenCodeManager` already defines 16 data-access tools and 7 A2UI render
|
|
tools with full implementations (`getToolDefinitions()`, `executeTool()`).
|
|
- `PreviewServer` provides the architectural pattern for an in-process HTTP
|
|
server with lifecycle management.
|
|
- Posts already have a `draft` status (DB-only, no disk writes until publish)
|
|
— the exact pattern needed for MCP draft posts.
|
|
- Scripts and templates are file-first (immediately persisted) — MCP proposals
|
|
need an in-memory staging layer before acceptance.
|
|
- **`@modelcontextprotocol/sdk` v1.27.1 and `@modelcontextprotocol/ext-apps`
|
|
v1.1.2 are installed.**
|
|
- **`ProposalStore` engine is implemented and tested (18 tests).**
|
|
- **`MCPServer` engine is implemented and tested (70 tests).** Standalone HTTP
|
|
server on port 4124, stateless mode (new `McpServer` per request), registers
|
|
5 static resources, 7 resource templates, 8 tools (6 model-facing +
|
|
2 app-only), 3 prompts, and 4 `ui://` review-app resources.
|
|
- **`mcp-views.ts` provides review HTML** for posts, scripts, templates, and
|
|
metadata diffs via `@modelcontextprotocol/ext-apps` App class.
|
|
- **Lifecycle integrated in `main.ts`** — MCP server starts on app ready and
|
|
cleans up on before-quit.
|
|
- **Origin validation** — rejects requests from non-localhost origins to
|
|
prevent DNS rebinding attacks.
|
|
- **`accept_proposal` / `discard_proposal` use app-only visibility** via
|
|
`registerAppTool` with `visibility: ["app"]` — hidden from the agent LLM.
|
|
|
|
### Design Principles
|
|
|
|
1. **Use all three MCP primitives** — expose blog data via the appropriate
|
|
MCP primitive for each use case:
|
|
- **Resources** for passive, read-only data (post content, media metadata,
|
|
category/tag lists, blog stats). These are application-controlled — the
|
|
host decides when to fetch them.
|
|
- **Tools** for parameterized actions (search, drafting, proposing changes).
|
|
These are model-controlled — the LLM decides when to call them.
|
|
- **Prompts** for user-triggered workflow templates (e.g., "draft a blog
|
|
post", "audit content quality"). These surface as slash commands in the
|
|
host UI.
|
|
|
|
2. **Tool annotations** — every tool declares MCP `annotations` to advertise
|
|
its behavior to the host:
|
|
- Read-only tools: `{ readOnlyHint: true, openWorldHint: false }`
|
|
- Proposal tools: `{ readOnlyHint: false, destructiveHint: false }`
|
|
- `accept_proposal`: `{ readOnlyHint: false, destructiveHint: false,
|
|
idempotentHint: true }`
|
|
- `discard_proposal`: `{ readOnlyHint: false, destructiveHint: true,
|
|
idempotentHint: true }`
|
|
|
|
All annotations are hints — hosts must not make security decisions based
|
|
on them alone, but they help hosts choose appropriate UI (e.g.,
|
|
auto-approving reads, showing confirmation for destructive actions).
|
|
|
|
3. **Tool metadata** — every tool includes `title` (human-readable display
|
|
name) and `description` (detailed explanation of what it does and when to
|
|
use it). Descriptions are critical — they are what the LLM reads to decide
|
|
whether and when to call a tool.
|
|
|
|
4. **Draft/Propose pattern for writes via MCP Apps** — every mutation goes
|
|
through a user-gated flow using the MCP Apps extension:
|
|
- Agent calls a `draft_*` or `propose_*` tool. These tools declare a
|
|
`_meta.ui.resourceUri` pointing to a review UI (`ui://` resource).
|
|
- The host (Claude Desktop, VS Code, etc.) renders the review app as a
|
|
sandboxed iframe inline in the conversation.
|
|
- The app shows the proposal (post preview, code block, metadata diff)
|
|
with accept/discard buttons. The agent LLM is **not** in the loop.
|
|
- User clicks accept → the app calls `accept_proposal` tool via the
|
|
MCP App bridge (postMessage) → server commits the change.
|
|
- User clicks discard → the app calls `discard_proposal` tool →
|
|
server cleans up.
|
|
- The tool result flows back to the agent so it can continue.
|
|
|
|
5. **Aligned with internal editors** — the MCP App review UIs mirror what
|
|
the app's own editors show (post metadata + content, script content +
|
|
validation, template content + validation, image metadata diff). This
|
|
keeps the user experience consistent whether they work inside bDS or
|
|
through an external agent.
|
|
|
|
6. **Capability negotiation** — during MCP initialization, the server
|
|
declares its supported capabilities: `tools`, `resources`, `prompts`.
|
|
For MCP Apps, the extension capability `io.modelcontextprotocol/ui` is
|
|
negotiated via the `extensions` field. The server checks whether the
|
|
client supports the Apps extension and adjusts proposal tool responses
|
|
accordingly (structured preview data for Apps-capable hosts, formatted
|
|
text for others).
|
|
|
|
7. **Input validation** — all tool inputs are validated at the MCP
|
|
boundary (via Zod schemas in `inputSchema`) before forwarding to
|
|
engine methods. Do not rely solely on downstream engine validation.
|
|
|
|
### Implementation Plan
|
|
|
|
#### 3.1 Dependencies
|
|
|
|
- `@modelcontextprotocol/sdk` — standard MCP server with transport handling.
|
|
- `@modelcontextprotocol/ext-apps` — MCP Apps extension for serving
|
|
interactive UI resources.
|
|
|
|
#### 3.2 Engine Class — `MCPServer`
|
|
|
|
Follow the `PreviewServer` pattern:
|
|
|
|
```
|
|
src/main/engine/MCPServer.ts
|
|
```
|
|
|
|
- Constructor accepts dependency injection (engines via getters).
|
|
- `start(port)` — create standalone HTTP server on port 4124 using
|
|
`StreamableHTTPServerTransport` in stateless mode.
|
|
- `stop()` — clean shutdown.
|
|
- Manages an in-memory `ProposalStore` for pending proposals (scripts,
|
|
templates, metadata changes). Posts use the existing draft mechanism instead.
|
|
- Serves `ui://` resources for the MCP App review UIs.
|
|
- Exposes three MCP primitive types:
|
|
- **Resources** — read-only blog data (posts, media, tags, categories,
|
|
stats) accessible via URI-based `resources/read`.
|
|
- **Tools** — parameterized actions (search, draft, propose, accept,
|
|
discard). Agent-facing tools are visible to the LLM; app-internal
|
|
tools (`accept_proposal`, `discard_proposal`) are called only by the
|
|
MCP App via the App Bridge.
|
|
- **Prompts** — user-triggered workflow templates surfaced as slash
|
|
commands in the host.
|
|
|
|
#### 3.3 Resources (Read-Only Data)
|
|
|
|
Expose blog data as MCP Resources using URI templates. Resources are
|
|
application-controlled — the host fetches them for context, they are not
|
|
actions. Each resource is registered via `resources/list` and read via
|
|
`resources/read`.
|
|
|
|
| Resource URI | Source | Description |
|
|
|----------------------------------|----------------------------------|------------------------------------|
|
|
| `bds://posts/{id}` | OpenCodeManager.read_post | Full post content + metadata |
|
|
| `bds://posts` | OpenCodeManager.list_posts | Paginated post list |
|
|
| `bds://media/{id}` | OpenCodeManager.get_media | Media item metadata |
|
|
| `bds://media` | OpenCodeManager.list_media | Paginated media list |
|
|
| `bds://tags` | OpenCodeManager.list_tags | All tags with counts |
|
|
| `bds://categories` | OpenCodeManager.list_categories | All categories |
|
|
| `bds://stats` | OpenCodeManager.get_blog_stats | Blog-wide statistics |
|
|
| `bds://posts/{id}/backlinks` | OpenCodeManager.get_post_backlinks | Posts linking to this post |
|
|
| `bds://posts/{id}/outlinks` | OpenCodeManager.get_post_outlinks | Posts this post links to |
|
|
| `bds://posts/{id}/media` | OpenCodeManager.get_post_media | Media attached to a post |
|
|
| `bds://media/{id}/posts` | OpenCodeManager.get_media_posts | Posts using a media item |
|
|
| `bds://media/{id}/image` | OpenCodeManager.view_image | Image binary (for visual context) |
|
|
|
|
Use `bds://` as the custom URI scheme. Parameterized URIs use MCP resource
|
|
templates (`resources/templates/list`).
|
|
|
|
Note: `notifications/resources/list_changed` is not emitted because the
|
|
server runs in stateless mode (new `McpServer` per request, no persistent
|
|
connection). If the server moves to session-based mode in the future,
|
|
change notifications should be added.
|
|
|
|
List resources (`bds://posts`, `bds://media`) support cursor-based
|
|
pagination following the MCP pagination spec. The initial response
|
|
includes a `nextCursor` if more results exist; the host passes it back
|
|
on the next `resources/read` call.
|
|
|
|
#### 3.4 Read Tools (Parameterized Queries)
|
|
|
|
Not all read operations fit the Resources model. Parameterized queries
|
|
that accept complex search criteria are better modeled as tools with
|
|
`readOnlyHint: true`.
|
|
|
|
| MCP Tool Name | Source | Annotations |
|
|
|------------------------|----------------------------------|------------------------------------------|
|
|
| search_posts | OpenCodeManager.search_posts | `readOnlyHint: true, openWorldHint: false` |
|
|
|
|
Each tool includes a `title`, a `description` explaining when it should
|
|
be used, and a JSON Schema `inputSchema`. `search_posts` accepts query
|
|
text, filters (status, category, tag, date range), and pagination
|
|
parameters (cursor, limit).
|
|
|
|
Exclude `update_post_metadata`, `update_media_metadata` (writes go through
|
|
proposals), and A2UI render tools (UI-specific, not useful for external
|
|
agents).
|
|
|
|
#### 3.5 Proposal Tools (Draft-Based Writes)
|
|
|
|
These tools stage content for user review. Each declares a `_meta.ui` field
|
|
pointing to a review UI resource, so the host renders an MCP App inline in the
|
|
conversation. Proposals have a TTL (e.g., 30 min) and are auto-discarded if
|
|
not accepted. All proposal tools use annotations
|
|
`{ readOnlyHint: false, destructiveHint: false }`.
|
|
|
|
##### 3.5.1 `draft_post`
|
|
|
|
Creates a draft post using the existing PostEngine draft workflow.
|
|
|
|
**Input:** `{ title, content (markdown), excerpt?, tags?, categoryId? }`
|
|
|
|
**Tool definition `_meta`:**
|
|
```json
|
|
{ "ui": { "resourceUri": "ui://bds/review-post" } }
|
|
```
|
|
|
|
**Action:**
|
|
1. Call `PostEngine.createPost()` with status `draft`.
|
|
2. Set tags and category if provided.
|
|
3. Return `{ proposalId (= postId), type: 'draftPost', preview: { title,
|
|
excerpt, tags, category, content, wordCount } }`.
|
|
|
|
**On user accept (via app):** `PostEngine.publishPost(postId)` — post
|
|
transitions to published, markdown file is written to disk.
|
|
|
|
**On user discard (via app):** `PostEngine.deletePost(postId)` — draft is
|
|
removed from the database.
|
|
|
|
##### 3.5.2 `propose_script`
|
|
|
|
Stages a Python script in memory for review.
|
|
|
|
**Input:** `{ title, content (python source), description? }`
|
|
|
|
**Tool definition `_meta`:**

|
|
description, content, syntaxValid, syntaxErrors? } }`.
|
|
|
|
**On user accept (via app):** `ScriptEngine.createScript()` — file + DB entry
|
|
created.
|
|
|
|
**On user discard (via app):** Remove from `ProposalStore` — nothing was
|
|
persisted.
|
|
|
|
##### 3.5.3 `propose_template`
|
|
|
|
Stages a Liquid template in memory for review.
|
|
|
|
**Input:** `{ title, content (liquid source), kind ('post'|'list'|'not-found'|
|
|
'partial') }`
|
|
|
|
**Tool definition `_meta`:**
|
|
```json
|
|
{ "ui": { "resourceUri": "ui://bds/review-template" } }
|
|
```
|
|
|
|
**Action:**
|
|
1. Validate Liquid syntax via `TemplateEngine.validateTemplate()`.
|
|
2. Store in `ProposalStore`.
|
|
3. Return `{ proposalId, type: 'template', preview: { title, slug, kind,
|
|
content, syntaxValid, syntaxErrors? } }`.
|
|
|
|
**On user accept (via app):** `TemplateEngine.createTemplate()` — file + DB
|
|
entry created.
|
|
|
|
**On user discard (via app):** Remove from `ProposalStore`.
|
|
|
|
##### 3.5.4 `propose_media_metadata`
|
|
|
|
Stages metadata changes for an existing media item.
|
|
|
|
**Input:** `{ mediaId, title?, alt?, caption? }`
|
|
|
|
**Tool definition `_meta`:**
|
|
```json
|
|
{ "ui": { "resourceUri": "ui://bds/review-metadata" } }
|
|
```
|

|
|
3. Store in `ProposalStore`.
|
|

|
|
|
|
**Input:** `{ postId, title?, excerpt?, slug?, tags? }`
|
|
|
|
**Tool definition `_meta`:**

|
|
|
|
**On user discard (via app):** Remove from `ProposalStore`.
|
|
|
|
#### 3.6 App-Internal Tools (Accept / Discard)
|
|
|
|
These tools are called by the MCP App (via the App Bridge's `tools/call`
|
|
mechanism), **not** by the agent LLM. They are registered with
|
|
`registerAppTool` from `@modelcontextprotocol/ext-apps` using
|
|
`visibility: ["app"]`, which signals to compliant hosts that these tools
|
|
should not be shown to or invoked by the model.
|
|
|
|
##### `accept_proposal`
|
|
|
|
**Input:** `{ proposalId }`
|
|
|
|
**Annotations:** `{ readOnlyHint: false, destructiveHint: false,
|
|
idempotentHint: true }`
|
|
|
|
Looks up the proposal type (draftPost, script, template, mediaMetadata,
|
|
postMetadata) and executes the commit action:
|
|
- draftPost → `PostEngine.publishPost()`
|
|
- script → `ScriptEngine.createScript()`
|
|
- template → `TemplateEngine.createTemplate()`
|
|
- mediaMetadata → `MediaEngine.updateMedia()`
|
|
- postMetadata → `PostEngine.updatePost()`
|
|
|
|
Returns `{ success, message }`.
|
|
|
|
##### `discard_proposal`
|
|
|
|
**Input:** `{ proposalId }`
|
|
|
|
**Annotations:** `{ readOnlyHint: false, destructiveHint: true,
|
|
idempotentHint: true }`
|
|
|
|
Executes the cleanup action:
|
|
- draftPost → `PostEngine.deletePost()`
|
|
- All others → remove from `ProposalStore`
|
|
|
|
Returns `{ success, message }`.
|
|
|
|
#### 3.7 MCP App Review UIs
|
|
|
|
The review UIs are HTML pages served as `ui://` resources by the MCP server.
|
|
They render inside the host's sandboxed iframe and use the
|
|
`@modelcontextprotocol/ext-apps` App class for bidirectional communication.
|
|
|
|
Each review app:
|
|
1. Receives the tool result data (proposal preview) from the host.
|
|
2. Renders a focused review interface:
|
|
- **Post review** (`ui://bds/review-post`): title, metadata fields,
|
|
rendered markdown content preview, word count.
|
|
- **Script review** (`ui://bds/review-script`): title, syntax-highlighted
|
|
Python code, validation status/errors.
|
|
- **Template review** (`ui://bds/review-template`): title, kind badge,
|
|
syntax-highlighted Liquid code, validation status/errors.
|
|
- **Metadata review** (`ui://bds/review-metadata`): side-by-side diff of
|
|
current vs proposed values for each changed field.
|
|
3. Shows accept and discard buttons.
|
|
4. On user action, calls `accept_proposal` or `discard_proposal` via the
|
|
App Bridge's `tools/call`.
|
|
5. Updates its UI to show the outcome ("Published", "Created", "Discarded").
|
|
|
|
These apps are small, self-contained HTML pages — the "slim MCP apps" concept.
|
|
They can share a common layout/style and differ only in the content they
|
|
render. Since the host provides the sandboxing, the apps don't need their own
|
|
authentication or security layer.
|
|
|
|
The review UIs should visually align with what the bDS internal editors show,
|
|
so the user experience is consistent. Where practical, share CSS/component
|
|
patterns between the bDS renderer UI and the MCP App review UIs.
|
|
|
|
#### 3.8 ProposalStore
|
|
|
|
In-memory store for pending proposals (not posts — those use the DB draft
|
|
mechanism):
|
|
|
|
```typescript
|
|
interface Proposal {
|
|
id: string;
|
|
type: 'script' | 'template' | 'mediaMetadata' | 'postMetadata';
|
|
data: Record<string, unknown>; // type-specific payload
|
|
createdAt: number;
|
|
ttlMs: number; // default 30 minutes
|
|
}
|
|
```
|
|
|
|
- Simple `Map<string, Proposal>` with periodic cleanup of expired entries.
|
|
- On app shutdown, all pending proposals are discarded (they were never
|
|
committed).
|
|
- No persistence needed — proposals are ephemeral by design.
|
|
|
|
For draft posts, the `proposalId` is the post ID itself. The `ProposalStore`
|
|
tracks a mapping from `proposalId → 'draftPost'` so the accept/discard
|
|
tools know to call PostEngine rather than look in the store.
|
|
|
|
#### 3.9 Transport
|
|
|
|
**Streamable HTTP** — standalone HTTP server on port 4124 using
|
|
`StreamableHTTPServerTransport` in stateless mode (new `McpServer` per
|
|
request). A single HTTP endpoint at `/mcp` accepts JSON-RPC POST
|
|
requests and responds with `application/json` or `text/event-stream`
|
|
(SSE).
|
|
|
|
**Security:**
|
|
|
|
- Bind to `127.0.0.1` (localhost only).
|
|
- Validate the `Origin` header on all requests — reject non-localhost
|
|
origins to prevent DNS rebinding attacks.
|
|
- Requests without an `Origin` header are allowed (CLI tools like curl
|
|
and local MCP clients typically do not send one).
|
|
|
|
#### 3.10 Lifecycle Integration
|
|
|
|
In `main.ts`:
|
|
|
|
- Initialize `MCPServer` in `initialize()`.
|
|
- Start alongside `PreviewServer` in `app.whenReady()`.
|
|
- Stop in `before-quit` handler (discard all pending proposals).
|
|
- Respect active project context (tools operate on the active project).
|
|
|
|
#### 3.11 Configuration
|
|
|
|
In `SettingsView`, add an "MCP Server" section:
|
|
|
|
- Enable/disable toggle.
|
|
- Port number (for HTTP transport).
|
|
- Show connection instructions (stdio command or URL).
|
|
- Proposal TTL setting (default 30 min).
|
|
|
|
#### 3.12 MCP Prompts (Workflow Templates)
|
|
|
|
Expose MCP Prompts for common agent workflows. Prompts are user-controlled —
|
|
they surface as slash commands or command palette entries in the host and
|
|
produce pre-structured messages that guide the LLM.
|
|
|
|
| Prompt Name | Arguments | Description |
|
|
|------------------------|----------------------------|--------------------------------------|
|
|
| `draft-blog-post` | `topic?`, `category?` | Guides agent through reading existing posts, understanding the blog's style, and drafting a new post on the given topic |
|
|
| `improve-media-metadata` | `scope` (`all`\|`missing`) | Guides agent through reviewing media items and proposing alt text, captions, and titles |
|
|
| `content-audit` | `category?` | Guides agent through reviewing posts for quality, broken links, missing metadata, and suggesting fixes |
|
|
|
|
Each prompt returns a structured message array (system + user messages) that
|
|
sets up the LLM with context about the blog and clear instructions for the
|
|
workflow. The host renders the prompt as a one-click action.
|
|
|
|
This is a lower-priority addition — prompts enhance discoverability but the
|
|
core read/write flow works without them.
|
|
|
|
#### 3.13 Example Workflows
|
|
|
|
**Agent creates a blog post:**
|
|
1. Agent LLM reads `bds://categories` and `bds://tags` resources to
|
|
understand the blog.
|
|
2. Agent LLM calls `draft_post({ title: "...", content: "...", tags: [...] })`.
|
|
3. MCP server creates draft post (DB only), returns preview data.
|
|
4. Host sees `_meta.ui.resourceUri`, fetches `ui://bds/review-post`, renders
|
|
sandboxed iframe inline in conversation.
|
|
5. Review app shows the full post preview with accept/discard buttons.
|
|
6. User clicks accept → app calls `accept_proposal` via App Bridge →
|
|
server publishes post → app shows "Published" → agent is informed.
|
|
|
|
**Agent writes a Python script:**
|
|
1. Agent LLM reads `bds://posts` resource to understand the content model.
|
|
2. Agent LLM calls `propose_script({ title: "Tag Cleanup", content: "..." })`.
|
|
3. MCP server validates syntax, stages in ProposalStore, returns preview.
|
|
4. Host renders `ui://bds/review-script` — shows syntax-highlighted code
|
|
with validation results.
|
|
5. User reviews code, clicks accept → app calls `accept_proposal` →
|
|
server creates script via ScriptEngine.
|
|
|
|
**Agent suggests image metadata:**
|
|
1. Agent LLM reads `bds://media/{id}/image` resource to see the image.
|
|
2. Agent LLM calls `propose_media_metadata({ mediaId, alt: "...",
|
|
caption: "..." })`.
|
|
3. MCP server computes diff, stages in ProposalStore, returns diff preview.
|
|
4. Host renders `ui://bds/review-metadata` — shows current vs proposed diff.
|
|
5. User reviews diff, clicks accept → metadata is updated.
|
|
|
|
#### 3.14 MCP Apps Client Support
|
|
|
|
MCP Apps are currently supported by Claude (claude.ai), Claude Desktop,
|
|
VS Code GitHub Copilot, Goose, Postman, and MCPJam. For hosts that don't
|
|
support MCP Apps, the proposal tools still return structured text content
|
|
that the agent can present as formatted text — the user would then need
|
|
to instruct the agent to accept or discard via conversation, falling back
|
|
to a simpler flow.
|
|
|
|
For hosts without Apps support, the MCP **Elicitation** primitive
|
|
(`elicitation/request`) can serve as a lighter-weight confirmation
|
|
mechanism — the server asks the user to confirm or reject a proposal via
|
|
a simple dialog rather than a full review UI. This requires the host to
|
|
support the `elicitation` capability. When neither Apps nor Elicitation is
|
|
available, fall back to text-based accept/discard in the conversation.
|
|
|
|
#### 3.15 Testing
|
|
|
|
- Unit tests for tool definition mapping (Anthropic → MCP format).
|
|
- Unit tests for resource URI resolution and resource template listing.
|
|
- Unit tests for `ProposalStore` (create, accept, discard, TTL expiry).
|
|
- Unit tests for accept/discard tool handlers.
|
|
- Unit tests for tool annotations (verify correct hints on each tool).
|
|
- Unit tests for prompt templates (verify message structure and arguments).
|
|
- Integration tests: draft_post → app accept flow, propose_script → app
|
|
discard flow.
|
|
- Integration tests: start MCP server, send tool calls, verify responses.
|
|
- Integration tests: capability negotiation (with/without Apps extension).
|
|
- Integration tests: resource read, resource list with pagination, resource
|
|
change notifications.
|
|
- MCP App UI tests: render review apps, simulate user actions, verify
|
|
tool calls through App Bridge.
|
|
- Security tests: Origin header validation, session management, rate
|
|
limiting (for Streamable HTTP transport).
|
|
- Follow existing engine test patterns with mocked dependencies.
|

## 4. AI Post Summary, Title & Slug Suggestions
|
|
|
|
### Goal
|
|
|
|
The post editor has AI buttons that generate summaries (excerpts), improved
|
|
titles, and better slugs — so the user can focus on writing content and let AI
|
|
handle the metadata.
|
|
|
|
### Current State
|
|
|
|
- `analyzeMediaImage()` in `OpenCodeManager` already implements the exact
|
|
pattern: one-shot AI call, JSON response, language-aware.
|
|
- `AISuggestionsModal` already provides the UI: loading state, field-by-field
|
|
checkboxes, current vs. suggested comparison, apply/cancel.
|
|
- The media editor has an "Analyze with AI" button in a quick-actions menu.
|
|
- The post editor metadata area has title, tags, author, slug, and categories
|
|
fields but no AI buttons.
|
|
- The `excerpt` field exists on `PostData` and can serve as the summary.
|
|
- Slug is read-only in the UI after first publish (auto-generated from title).
|
|
|
|
### Implementation Plan
|
|
|
|
#### 4.1 Backend — `analyzePost()` in OpenCodeManager
|
|
|
|
Add a new method following the `analyzeMediaImage()` pattern:
|
|
|
|
**Input:** `postId: string, language: string`
|
|
|
|
**Process:**
|
|
1. Load post content, title, excerpt, and slug via `PostEngine`.
|
|
2. Build a system prompt:
|
|
```
|
|
You are a blog editor assistant. Analyze the following blog post and suggest
|
|
improvements. Return a JSON object with:
|
|
- "title": a clear, engaging title for this post
|
|
- "excerpt": a 2-3 sentence summary suitable for overview pages
|
|
- "slug": a concise, SEO-friendly URL slug (lowercase, hyphens only)
|
|
Respond in {language}. Return only the JSON object.
|
|
```
|
|
3. Send post content as user message to OpenCode Zen API.
|
|
4. Parse JSON response.
|
|
5. Return `{ success, title?, excerpt?, slug?, error? }`.
|
|
|
|
Register IPC handler: `chat:analyzePost`.
|
|
|
|
#### 4.2 Frontend — Post Editor AI Button
|
|
|
|
In the post editor metadata area (`Editor.tsx`, around line 720):
|
|
|
|
- Add a "Quick Actions" dropdown button (same pattern as media editor at
|
|
line 1242).
|
|
- Menu item: "Suggest Title, Summary & Slug" with a robot icon.
|
|
- On click: call `window.electronAPI.chat.analyzePost(postId, projectLanguage)`.
|
|
- Show `AISuggestionsModal` with the results.
|
|
|
|
#### 4.3 Extend AISuggestionsModal
|
|
|
|
The modal currently supports `title`, `alt`, `caption` fields. Adapt it to
|
|
also support a post mode with `title`, `excerpt`, `slug` fields:
|
|
|
|
- Add a `mode` prop (`'media'` | `'post'`) or make field configuration
|
|
dynamic.
|
|
- For post mode, show title, excerpt, and slug fields.
|
|
- Slug field should show a warning that it only applies to unpublished posts.
|
|
|
|
Alternatively, keep the modal generic and pass field definitions as props:
|
|
```typescript
|
|
interface SuggestionField {
|
|
key: string;
|
|
label: string; // i18n key
|
|
currentValue: string;
|
|
suggestedValue?: string;
|
|
warning?: string; // e.g., "slug is locked after first publish"
|
|
}
|
|
```
|
|
|
|
#### 4.4 Applying Suggestions
|
|
|
|
On "Apply Selected":
|
|
|
|
- Title: update via existing `onTitleChange` handler.
|
|
- Excerpt: update via `onExcerptChange` (may need to add this handler if not
|
|
present — excerpt editing may need a field in the metadata area).
|
|
- Slug: only apply if post has never been published. Show a warning and disable
|
|
the checkbox if the post has `publishedAt` set.
|
|
|
|
#### 4.5 i18n
|
|
|
|
Add keys to all 5 locale files:
|
|
|
|
- `aiSuggestions.postTitle`, `aiSuggestions.excerptField`,
|
|
`aiSuggestions.slugField`
|
|
- `aiSuggestions.analyzingPost`
|
|
- `aiSuggestions.slugLockedWarning`
|
|
- `postEditor.quickActions`, `postEditor.analyzeWithAI`
|
|
|
|
#### 4.6 Excerpt Field in Editor
|
|
|
|
If the excerpt/summary is not currently editable in the post metadata area,
|
|
add a multi-line text field for it between title and tags. This is needed both
|
|
for manual editing and for applying AI suggestions.
|
|
|
|

|
|
|
|
## 5. Drag-and-Drop Image Insertion
|
|
|
|
### Goal
|
|
|
|
Users can drag image files from the filesystem onto the editor to insert them.
|
|
Dropped files are automatically imported into the media library and inserted
|
|
as markdown images.
|
|
|
|
### Current State
|
|
|
|
- Images are inserted only via `InsertModal` (browse media library or enter
|
|
URL).
|
|
- `MediaEngine.importMedia(sourcePath)` handles file import, thumbnail
|
|
generation, and database indexing.
|
|
- `imageResolverPlugin` already converts relative media paths to `bds-media://`
|
|
protocol URLs for editor display.
|
|
- `LinkedMediaPanel` has working drag-drop for reordering (reference pattern).
|
|
- `insertImageCommand` from Milkdown inserts image nodes into the editor.
|
|
|
|
### Implementation Plan
|
|
|
|
#### 5.1 ProseMirror Drop Plugin
|
|
|
|
Create a new plugin in `src/renderer/plugins/dropImagePlugin.ts` following the
|
|
`imageResolverPlugin` pattern:
|
|
|
|
```typescript
|
|
// Pseudo-structure
|
|
export const dropImagePlugin = $prose(() => {
|
|
return new Plugin({
|
|
props: {
|
|
handleDOMEvents: {
|
|
drop: (view, event) => {
|
|
// 1. Check for files in dataTransfer
|
|
// 2. Filter to image types
|
|
// 3. Get file paths (Electron exposes .path on File objects)
|
|
// 4. For each file: import via IPC, insert into editor
|
|
// 5. Return true to prevent default
|
|
},
|
|
dragover: (view, event) => {
|
|
// Show drop indicator if files are images
|
|
}
|
|
}
|
|
}
|
|
});
|
|
});
|
|
```
|
|
|
|
#### 5.2 Drop Handler Flow
|
|
|
|
For each dropped file:
|
|
|
|
1. **Validate** — check file extension against supported image types (jpg,
|
|
png, gif, webp, svg, bmp).
|
|
2. **Import** — call `window.electronAPI.media.import(file.path)`. This returns
|
|
`MediaData` with the media ID and file path.
|
|
3. **Insert** — use `insertImageCommand` with `{ src: relativePath, alt: '' }`
|
|
where `relativePath` is the media's storage path (e.g.,
|
|
`media/2025/01/uuid.jpg`).
|
|
4. **Link** — call `window.electronAPI.postMedia.link(postId, mediaId)` to
|
|
track the relationship.
|
|
5. **Resolve** — the existing `imageResolverPlugin` will automatically convert
|
|
the relative path to a `bds-media://` URL for display.
|
|
|
|
#### 5.3 Visual Feedback
|
|
|
|
- On `dragover` with image files: add a CSS class to the editor container
|
|
showing a drop zone indicator (border highlight or overlay).
|
|
- On `dragleave` / `drop`: remove the indicator.
|
|
- During import (for large files): show a small inline spinner or toast.
|
|
|
|
#### 5.4 Integration into MilkdownEditor
|
|
|
|
In `MilkdownEditor.tsx`, register the new plugin alongside existing plugins:
|
|
|
|
```typescript
|
|
import { dropImagePlugin } from '../../plugins/dropImagePlugin';
|
|
|
|
// In the editor setup, add to the plugin list
|
|
.use(dropImagePlugin)
|
|
```
|
|
|
|
Pass `postId` and the import callback to the plugin via the editor context or
|
|
a shared ref.
|
|
|
|
#### 5.5 Paste Support (Optional Extension)
|
|
|
|
The same plugin can handle `paste` events with image files:
|
|
|
|
- Check `clipboardData.files` for images.
|
|
- Same import → insert → link flow as drop.
|
|
- This handles screenshots pasted from the clipboard.
|
|
|
|
#### 5.6 Error Handling
|
|
|
|
- Non-image files: ignore silently (don't prevent default, let editor handle
|
|
text drops normally).
|
|
- Import failure: show toast with error message, don't insert anything.
|

- Multiple files: process sequentially, insert at cursor position for first,
|
|
then append after each previous insertion.

|
#### 5.7 Testing
|
|
|
|
- Unit test the plugin's file validation logic.
|
|
- Integration test: mock `electronAPI.media.import`, verify correct calls and
|
|
editor state after drop.
|
|
- Test edge cases: non-image files, failed imports, multiple simultaneous
|
|
drops.
