A comprehensive strategy for professionalizing social media marketing across Brad’s side projects (primarily Mystery Hound screen printing) using self-hosted automation while maintaining human creative control.

Executive Summary

Brad devotes 2-3 full days per month to each side project, making those content generation sessions critical. The proposed pipeline automates the mechanical work—queuing, editing coordination, scheduling, cross-posting—while preserving human judgment for creative decisions and community engagement.

Core Architecture:

  1. Content creation during focused work sessions (screen printing, streaming)
  2. Queue management via self-hosted Grist (spreadsheet-database hybrid)
  3. Content editing via Fiverr contractors, agent automation, or Brad
  4. Publishing workflow using POSSE principles (Publish Own Site, Syndicate Elsewhere)
  5. Cross-platform scheduling via self-hosted Mixpost

Key Principles:

  • Self-hosted, no recurring SaaS fees
  • Automation handles mechanics, humans handle creativity
  • POSSE maintains content ownership
  • Reusable across multiple projects
  • Actually used > elaborate but unused

Component Analysis

Content Queue/Database: Grist

What it is: Self-hosted spreadsheet-database hybrid with REST API, custom widgets, and relational data capabilities.

Core Capabilities

API Features:

  • Full REST API for CRUD operations on documents, tables, records, columns
  • Bearer token authorization
  • Supports bulk operations (BulkAddRecord, BulkUpdateRecord, BulkRemoveRecord)
  • Webhook support for real-time notifications
  • Integrates with n8n, Make.com, Zapier

Data Management:

  • Native attachment column type for files/media
  • Relational linking between tables
  • Python formulas for computed fields
  • Access controls and permissions
  • CSV/Excel/Google Drive import/export

Docker Deployment:

See Docker deployment best practices for detailed configuration guidance.

  • Official image: gristlabs/grist:latest
  • SQLite-based for easy backups
  • Configurable via environment variables
  • Handles 89k+ records with fast filtering
  • Self-contained, no special server requirements

Kanban Widget Implementation

Reality Check: Kanban support exists via community-built custom widgets, not as a native feature.

How it works:

  1. Add custom widget to Grist page
  2. Use community code (e.g., from GitLab: grist_kanban.html)
  3. Configure data source (any Grist dataset)
  4. Drag-and-drop task management

Limitations:

  • Media preview in kanban view requires custom development
  • No native drag-and-drop file uploads to cards
  • Community widget maturity varies
  • May need JavaScript extensions for full functionality

Workaround: Use standard table view for media attachments, kanban for status visualization.

Permissions & Sharing

For Fiverr Collaborators:

  • Share specific documents with email-based access
  • Role-based permissions (owner, editor, viewer)
  • Can grant edit access to specific tables
  • API access via separate API keys

Example workflow:

  1. Create “Content Editing” document
  2. Share with Fiverr editor’s email
  3. Editor sees only assigned tasks
  4. Editor uploads finished content to attachment column
  5. Updates status to ready_to_publish

Pros & Cons

Pros:

  • ✅ Hybrid spreadsheet/database—familiar UX, powerful backend
  • ✅ Native attachment handling for media files
  • ✅ Comprehensive REST API for agent automation
  • ✅ Self-hosted, open source (MIT license)
  • ✅ Docker deployment, easy backups (SQLite)
  • ✅ Python formulas for custom logic
  • ✅ Good integration ecosystem (n8n, webhooks)

Cons:

  • ❌ Kanban widget not native—community code required
  • ❌ Media preview in kanban needs custom work
  • ❌ Steeper learning curve than simple kanban tools
  • ❌ Custom widget development requires JavaScript knowledge
  • ❌ Less visually polished than dedicated kanban tools

Alternative Queue Systems Comparison

ToolProsConsVerdict
VikunjaMost feature-rich; multiple views (list, gantt, table, kanban); imports from Todoist/Trello; nested projectsNo native media attachments in kanban context; more complex than neededBetter for comprehensive project management, overkill for simple content queue
PlankaLightweight, elegant Trello clone; simple setupLimited feature documentation; no robust API details found; minimal media handlingToo simple for content workflow needs
KanboardSimplest deployment; basic but solid kanbanMinimal integrations; limited customization; lower community activityGood for pure kanban, lacks database features
WeKanHighly visual; strong collaboration features; 20.7K GitHub starsRequires daily backups (data loss risks); MongoDB backend (heavier); security updates criticalRisky for production without dedicated maintenance
GristSpreadsheet familiarity + database power; API-first; media attachments native; flexible data modelKanban requires custom widgetBest fit: combines queue (table) + visualization (kanban) + automation (API) + media handling

Recommendation: Grist for its unique combination of spreadsheet UX, database capabilities, and API automation. The kanban widget limitation is acceptable since table view works well for media-heavy content management, and agents interact via API anyway.

Social Scheduling/Posting: Mixpost

What it is: Self-hosted, open-source social media scheduling platform with multi-platform support and REST API.

Platform Support

Fully Supported Platforms:

  • Instagram (posts, reels, stories)
  • TikTok (videos, thumbnails)

Recommendation: Mixpost Pro. The one-time cost vs. recurring SaaS fees, combined with full API access for automation, makes it the clear choice for Brad’s self-hosted infrastructure philosophy.

POSSE Implementation

POSSE (Publish Own Site, Syndicate Elsewhere) is an IndieWeb principle: publish content on your own domain first, then distribute copies to third-party platforms. This maintains content ownership, establishes canonical URLs, and future-proofs against platform shutdowns.

Architecture

[Content Creation]
      ↓
[Publish to mysteryhound.press]
      ↓
[Generate SEO-optimized post with metadata]
      ↓
[RSS feed updates]
      ↓
[Agent monitors RSS/webhook]
      ↓
[Agent adapts content per platform]
      ↓
[Mixpost API schedules syndicated posts]
      ↓
[Auto-publish with link to canonical URL]

CMS Choice: Ghost Blog

AspectDetails
PlatformGhost (open-source publishing platform)
RSS/WebhooksNative RSS, webhook plugins available
RSS/WebhooksNative RSS/JSON feeds, webhook support via integrations
MediaBuilt-in media library with CDN support
SEOBuilt-in SEO features, clean URLs, meta tags, sitemaps
DeploymentDocker/Node.js, SQLite or MySQL backend
Workflow FitQuick posting from mobile, web-based editor, supports scheduled publishing

For POSSE with Brad’s workflow:

Deployment: Ghost for the canonical site (mysteryhound.press).

Rationale:

  • Brad needs to post quickly during 2-3 day work sessions
  • Ghost mobile app enables “post from workshop” workflow
  • Native RSS/JSON feeds for agent monitoring
  • Webhook support via Ghost integrations for real-time agent notification
  • Built-in media library handles workshop photos easily
  • Self-hosted, modern Node.js stack (see static site hosting)

Agent Monitoring Implementation

Option 1: RSS Polling (Simplest)

# Agent polls RSS feed every 5 minutes
import feedparser
 
def check_for_new_posts():
    feed = feedparser.parse('https://mysteryhound.press/feed/')
    latest_post = feed.entries[0]
    
    if latest_post.id not in seen_posts:
        process_new_post(latest_post)
        seen_posts.add(latest_post.id)

Option 2: Webhook Push (Better)

# Ghost sends webhook on new post
# Agent receives webhook at endpoint
 
@app.route('/webhook/new-post', methods=['POST'])
def handle_new_post():
    post_data = request.json
    
    # Immediate processing, no polling delay
    process_new_post(post_data)
    
    return {'status': 'received'}, 200

Recommendation: Start with RSS polling (no Ghost configuration needed), migrate to webhooks once workflow is validated.

Syndication Agent Skill

Core responsibilities:

  1. Detect new post on canonical site
  2. Extract content (title, body, images, tags)
  3. Generate platform-specific adaptations
  4. Upload media to Mixpost
  5. Schedule posts via Mixpost API
  6. Track syndication status in Grist

Platform-Specific Adaptations:

PlatformAdaptation Strategy
Instagram- Use first image or create gallery
- Caption: 2200 char limit, emoji-friendly
- Add relevant hashtags (research: 3-5 optimal)
- Include link in bio mention
- Size: 1080x1080 (square) or 1080x1350 (portrait)
TikTok- Video required (use workshop clips)
- Caption: 150 chars, punchy
- Trending audio if applicable
- Size: 1080x1920 (9:16 vertical)
X/Twitter- Thread if needed (280 chars/tweet)
- Lead with hook
- Include image (better engagement)
- Link to canonical post
- Size: 1200x675 (16:9)
YouTube- Short clips (60 sec) or full process videos
- SEO title and description
- Tags from post metadata
- Thumbnail: 1280x720
- Link to mysteryhound.press in description
Threads- Similar to X but more casual
- 500 char limit
- Good for behind-the-scenes
LinkedIn- Professional framing (“process engineering”)
- Longer-form acceptable
- Emphasize craftsmanship, business aspects

Example caption adaptation:

Original post (Ghost):

Mystery Hound just finished a 4-color print run for a local band. 
The halftone work on this design was challenging—had to get the 
screens perfectly aligned for the color blend to work. 150 shirts 
printed, and the client is stoked. Check out the process photos.

[3 workshop photos]

Instagram adaptation:

🎨 4-color halftone magic ✨

Challenge: Perfect screen alignment for seamless color blends
Result: 150 happy shirts for @localbandname

The satisfaction when that registration hits just right 👌

Full process on mysteryhound.press (link in bio)

POSSE Skill Implementation

Skill structure:

name: posse-syndicate
description: Monitor canonical site and syndicate to social platforms
triggers:
  - RSS feed update (mysteryhound.press/feed/)
  - Webhook from Ghost
dependencies:
  - brand-voice skill (Mystery Hound)
  - mixpost-api skill
  - image-processor skill
config:
  canonical_site: "https://mysteryhound.press"
  rss_feed: "https://mysteryhound.press/feed/"
  check_interval: "5 minutes"
  platforms: ["instagram", "tiktok", "twitter", "youtube", "threads"]

Agent workflow:

  1. New post detected → extract content
  2. Load Mystery Hound brand voice guidelines
  3. For each platform:
    • Adapt caption using brand voice
    • Resize/reformat images to platform specs
    • Generate platform-specific metadata
  4. Upload media to Mixpost
  5. Create scheduled post via Mixpost API
  6. Log to Grist: syndication_status table
  7. If error → alert Brad

Pros & Cons

Pros:

  • ✅ Content ownership—you control canonical source
  • ✅ Platform independence—not reliant on any social network
  • ✅ SEO benefits—own site is searchable, indexable
  • ✅ Future-proof—content survives platform shutdowns
  • ✅ Cross-posting automation—write once, publish everywhere
  • ✅ Consistent branding—all posts link back to mysteryhound.press

Cons:

  • ❌ Requires maintaining own website
  • ❌ Additional step in workflow (post to site first)
  • ❌ Agent dependency—automation must work reliably
  • ❌ Platform-specific content loses some native features (e.g., Instagram polls)
  • ❌ Initial setup complexity

Recommendation: Implement POSSE for Mystery Hound. The content ownership and SEO benefits align with building a long-term brand. For smaller/experimental projects, direct-to-platform posting is acceptable.

Automation Opportunities

What Can Realistically Be Automated

1. Clip Extraction from VODs

Tools: yt-dlp + ffmpeg + chat activity analysis

Workflow:

# Download Twitch VOD
yt-dlp "https://www.twitch.tv/videos/VOD_ID"
 
# Download chat log
yt-dlp --write-chat "https://www.twitch.tv/videos/VOD_ID"
 
# Analyze chat for activity spikes (Python script)
# Peaks indicate interesting moments (reactions, questions)
python analyze_chat_peaks.py chat.json > peaks.txt
 
# Extract clips at peak times
while read start duration; do
  ffmpeg -ss $start -t $duration \
    -i "$(yt-dlp -g VOD_URL)" \
    -c copy "clip_${start}.mp4"
done < peaks.txt

Agent implementation:

  • Monitor Twitch for new VODs (RSS/API)
  • Auto-download + chat log
  • Analyze chat for activity spikes (messages/10sec > threshold)
  • Extract 30-60 sec clips at peaks
  • Upload to Grist queue with status needs_review
  • Brad reviews clips, approves for editing

Reality check: This creates candidate clips. Human review required—not all chat spikes are interesting (could be bot spam, off-topic). Agent reduces 3-hour VOD to 10-15 candidate clips.

Confidence level: 🟢 High. Technical implementation is straightforward. Saves significant time.

2. Caption Generation (Brand Voice)

Tools: LLM (Claude, GPT-4) + brand voice training + platform guidelines

Training approach:

# Brand voice prompt for Mystery Hound
brand_voice_prompt = """
You are writing social media captions for Mystery Hound, 
a screen printing studio. Brand voice:
 
- Tone: Confident, educational, slightly irreverent
- Style: Mix of craftsmanship pride and "hell yeah" energy
- Audience: DIY makers, band merch buyers, print nerds
- Vocabulary: Technical terms explained accessibly
- Emoji: Occasional, purposeful (🎨 ✨ 🔥 👌)
- Hashtags: 3-5 relevant, mix of broad (#screenprinting) 
  and niche (#halftoneprinting)
 
Example posts:
{include 10-15 top-performing posts}
 
Generate a caption for: {post_content}
Platform: {platform}
Keep it: {platform_specific_guidelines}
"""

Agent implementation:

  1. New content in Grist queue (status: ready_to_publish)
  2. Agent reads content + images
  3. Generates initial caption using brand voice prompt
  4. Adapts for each platform (length, style, hashtags)
  5. Saves draft to Grist with status caption_drafted
  6. Brad reviews/edits/approves

Reality check: AI-generated captions are 85% ready. Human editing required for:

  • Nuanced brand moments (inside jokes, references)
  • Sensitive topics (politics, current events)
  • Platform-specific trends (TikTok sounds, Twitter discourse)
  • Final creative approval

Confidence level: 🟢 High. Modern LLMs excel at style mimicry. With good training examples, output is consistently on-brand. Human editing time reduced from 10 min/caption to 2 min/caption.

3. Image Resizing/Reformatting

Tools: ImageMagick, Python PIL, ffmpeg (for video)

Platform specifications:

PlatformOptimal SizeAspect RatioFormatNotes

YouTube Thumbnail1280x72016:9JPG/PNGHigh-res, max 2MB
YouTube Shorts1080x19209:16MP4Vertical video

Agent implementation:

# Automated image processing pipeline
def process_image_for_platforms(source_image_path):
    platforms = {
        'instagram_feed': {'size': (1080, 1080), 'mode': 'crop_center'},
        'instagram_portrait': {'size': (1080, 1350), 'mode': 'crop_top'},
        'instagram_story': {'size': (1080, 1920), 'mode': 'crop_center'},
        'tiktok': {'size': (1080, 1920), 'mode': 'crop_center'},
        'twitter': {'size': (1200, 675), 'mode': 'crop_center'},
        'youtube_thumb': {'size': (1280, 720), 'mode': 'crop_center'},
    }
    
    processed = {}
    for platform, specs in platforms.items():
        processed[platform] = resize_and_crop(
            source_image_path, 
            specs['size'], 
            specs['mode']
        )
    
    return processed

Reality check: Fully automatable. Only edge case: artistic framing decisions (which part of image to crop). Solution: Use center crop for automation, Brad can manually override for hero images.

Confidence level: 🟢 Very high. This is pure mechanical work—perfect for automation. Saves 5-10 min per post.

4. Scheduling Optimization

Tools: Mixpost smart scheduling + historical analytics

Strategy:

  • Mixpost Pro has “optimal time” scheduling based on audience engagement patterns
  • Agent can analyze past post performance to refine timing
  • Initial schedule: industry best practices per platform
  • Iterative: learn from analytics, adjust

Platform best practices (starting point):

PlatformBest Times (General)Best DaysNotes
Instagram11am-1pm, 7pm-9pmWed-FriLunchtime, evening scroll
TikTok6am-10am, 7pm-11pmTue-ThuMorning commute, evening
X/Twitter8am-10am, 6pm-9pmWed-FriCommute hours, news cycle
YouTube2pm-4pm, 8pm-10pmFri-SatAfter work/school
LinkedIn8am-10am, 12pm, 5pm-6pmTue-WedBusiness hours

Agent implementation:

  1. When agent schedules post via Mixpost API
  2. Use schedule_time: 'optimal' parameter
  3. Mixpost calculates best time based on past engagement
  4. Fallback to platform best practices if insufficient data
  5. Log actual publish time + engagement metrics
  6. Refine over time

Reality check: Generic “best times” are guidelines, not rules. Audience-specific patterns matter more. Need 2-3 months of data for reliable optimization.

Confidence level: 🟡 Medium-high. Mixpost handles this well. Main limitation: requires consistent posting history for accurate optimization. Start with best practices, improve over time.

5. Queue Health Monitoring

Tools: Grist API + agent scheduled task

Implementation note: Queue monitoring should follow idempotent automation principles—running the check multiple times should not create duplicate alerts or modify queue state.

Monitoring logic:

# Run daily at 9am
def check_queue_health():
    queue = grist_api.get_records('content_queue')
    
    # Count posts by status
    ready_to_publish = [r for r in queue if r.status == 'ready_to_publish']
    scheduled = grist_api.get_records('scheduled_posts')
    
    # Calculate days of content remaining
    posts_per_day = 1  # Mystery Hound posts daily
    days_remaining = len(ready_to_publish) / posts_per_day
    
    # Alert if running low
    if days_remaining < 3:
        send_alert(f"⚠️ Queue low: {days_remaining} days of content remaining")
    
    # Check for stalled content
    stalled = [r for r in queue 
               if r.status == 'in_editing' 
               and r.updated_at < (now - 72.hours)]
    
    if stalled:
        send_alert(f"⚠️ {len(stalled)} items stalled in editing for 3+ days")
    
    # Summary report
    return {
        'ready_to_publish': len(ready_to_publish),
        'days_remaining': days_remaining,
        'in_editing': len([r for r in queue if r.status == 'in_editing']),
        'needs_editing': len([r for r in queue if r.status == 'needs_editing']),
        'stalled': len(stalled)
    }

Alert delivery: Discord webhook, email, or morning briefing integration.

Reality check: Fully automatable. Useful for maintaining consistent posting cadence during Brad’s off weeks.

Confidence level: 🟢 Very high. This is pure data reporting. Saves mental overhead of manually tracking queue status.

6. Brief Generation for Fiverr Editors

Tools: LLM + Grist data + template

Brief template:

# Edit Request: {content_title}
 
## Project
Mystery Hound screen printing
 
## Content Type
{content_type}  # e.g., "Workshop process video", "Product photo set"
 
## Source Material
- Files: {list_of_raw_files}
- Duration/Count: {metadata}
- Shot on: {date}
 
## Editing Requirements
 
### Video Edit (if applicable)
- Trim to 30-60 seconds
- Remove dead air and mistakes
- Color correction: warm, workshop vibe (reference: {example_video_link})
- Add subtle music: upbeat, energetic (no vocals)
- Text overlays: product name, key steps (font: {brand_font})
- Export: 1080x1920 (vertical) + 1080x1080 (square)
 
### Photo Edit (if applicable)
- Color correct: warm tones, accurate colors (reference: {example_photo_link})
- Crop to highlight subject (leave room for text overlay)
- Remove distractions in background
- Export: high-res (3000px wide) + Instagram optimized (1080x1350)
 
### Brand Guidelines
- Style reference: {link_to_mystery_hound_brand_doc}
- Previous work examples: {link_to_portfolio}
 
## Delivery
- Upload finished files to: {grist_upload_link}
- Update status in Grist to "ready_to_publish"
- Expected turnaround: {deadline}
 
## Questions?
Message Brad on Fiverr or Discord: {contact_info}

Agent implementation:

  1. Brad marks content in Grist with status needs_editing + assigns editor
  2. Agent generates brief from Grist data + template
  3. Agent posts brief to Fiverr order + sends to editor email
  4. Editor completes work, uploads to Grist
  5. Agent detects status change, notifies Brad for approval

Reality check: Brief generation is automatable. Editor selection and quality assurance remain human tasks. A bad editor wastes money regardless of brief quality.

Confidence level: 🟢 High. This is template + data interpolation. Saves 10-15 min per brief.

Human-Required Tasks

What Cannot/Should Not Be Automated

1. Content Creation Itself

Why: Creative vision, spontaneous moments, authentic storytelling.

Human role:

  • Shooting photos/videos during work sessions
  • Framing shots for visual interest
  • Capturing “money shots” (print reveal, color blend, etc.)
  • Deciding what’s worth documenting

Agent role: None. This is the core creative work.

2. Final Creative Approval

Why: Brand intuition, contextual judgment, “does this feel right?”

Human role:

  • Review AI-generated captions for tone/accuracy
  • Approve clip selections from VOD extracts
  • Final yes/no on publishing
  • Override scheduling if current events make post inappropriate

Agent role: Generate drafts, flag for review, execute after approval.

Example scenario: Agent generates caption referencing “blow up” (screen printing term). On day of actual explosion news, human catches this and revises. Agent can’t make this contextual judgment.

3. Community Engagement/Replies

Why: Authenticity, relationship building, nuanced communication.

Human role:

  • Reply to comments (especially questions)
  • DMs with potential clients
  • Engaging with other makers’ content
  • Building community relationships

Agent role: Flag comments needing response, draft suggested replies, but human sends.

Reality check: AI replies are detectable and off-putting. People follow Mystery Hound for Brad’s expertise and personality, not a bot. Engagement must be authentic.

4. Brand Direction Decisions

Why: Strategic vision, market positioning, creative evolution.

Human role:

  • Defining brand voice evolution
  • Choosing which projects to feature
  • Deciding platform strategy (double down on TikTok? scale back Twitter?)
  • Setting content themes (focus on process? products? education?)

Agent role: Provide analytics and recommendations, execute chosen strategy.

5. Editor Selection and Management

Why: Quality judgment, creative compatibility, reliability assessment.

Human role:

  • Hiring Fiverr editors (reviewing portfolios, test edits)
  • Evaluating editor quality
  • Providing feedback on edits
  • Deciding when to fire/replace editor

Agent role: Generate briefs, track turnaround times, flag missed deadlines.

Reality check: A bad editor produces unusable content. This hiring decision has high stakes and requires human judgment.

6. Platform Trend Adaptation

Why: Cultural literacy, meme understanding, timing instinct.

Human role:

  • Recognizing trending sounds/formats on TikTok
  • Jumping on relevant Twitter discourse
  • Adapting posts to current platform culture

Agent role: Flag trending topics/hashtags, suggest adaptations, but human decides fit.

Example: TikTok trending sound fits Mystery Hound vibe → Brad decides to shoot specific content for it. Agent can’t make this creative leap.

The Human-Agent Balance

Good automation:

  • Automate mechanics (resizing, scheduling, formatting)
  • Generate drafts for human refinement
  • Handle monitoring and alerting
  • Execute decisions reliably

Bad automation:

  • Trying to replace human creativity
  • Auto-publishing without approval
  • Auto-replying to community
  • Making brand strategy decisions

Goal: Agent acts as tireless assistant, not creative replacement. Brad’s time shifts from mechanical work (resizing images, remembering to post) to creative work (making content, engaging community).

Implementation Roadmap

Phase 1: Foundation (Weeks 1-2)

Goal: Get basic infrastructure running.

Tasks:

  1. Deploy Grist

    • Docker setup on homelab
    • Create “Content Queue” document
    • Define tables:
      • content_queue: raw uploads, status tracking
      • scheduled_posts: published content tracking
      • analytics: engagement metrics
    • Set up API access (generate API key)
    • Test: manually add content, update status
  2. Deploy Mixpost Pro

    • Docker setup on homelab
    • Purchase Pro license ($299)
    • Connect social accounts (Instagram, TikTok, X, YouTube)
    • Test: manually create and schedule a post
    • Verify API access with test call
  3. Set up mysteryhound.press (Ghost)

    • Ghost blog deployment (Docker)
    • SEO plugin (Rank Math or Yoast)
    • RSS feed verification
    • Test: publish post, verify RSS updates

Deliverable: All three systems running and accessible. Can manually post to Ghost, add to Grist queue, schedule via Mixpost.

Validation: Manually walk through entire workflow once to confirm all pieces work.

Phase 2: Basic Automation (Weeks 3-4)

Goal: Automate the boring parts.

Tasks:

  1. Image Processing Skill

    • Script to resize images to platform specs
    • Integration with Grist (read attachments, process, save variants)
    • Test on 5-10 real workshop photos
  2. Grist Queue Monitoring

    • Daily script: check queue health
    • Alert if content running low (<3 days)
    • Alert if items stalled in editing
    • Integrate with Discord webhook for alerts
  3. Manual POSSE Workflow

    • Brad posts to Ghost
    • Agent detects via RSS polling (5 min intervals)
    • Agent reads post content
    • Agent logs to Grist: “new post detected, needs syndication”
    • Brad manually creates Mixpost posts (for now)

Deliverable: Automated image processing + queue monitoring. Semi-automated POSSE (agent detects, human syndicates).

Validation: One week of real usage. Brad posts 2-3 times, confirms automation works.

Phase 3: Caption Generation (Weeks 5-6)

Goal: AI writes first drafts of captions.

Tasks:

  1. Brand Voice Training

    • Collect 10-15 top-performing Mystery Hound posts

  2. Caption Generation Skill

    • Reads post content from Ghost (via RSS/API)
    • Generates platform-specific captions (Instagram, TikTok, X, YouTube)
    • Saves drafts to Grist with status caption_drafted
    • Sends notification: “Captions ready for review”
  3. Review Workflow

    • Brad reviews AI captions in Grist
    • Edits as needed
    • Approves (status → ready_to_publish)

Deliverable: AI generates captions; human reviews/approves.

Validation: Generate 10 captions, measure edit time. Goal: <2 min editing per caption (vs. 10 min writing from scratch).

Phase 4: Full POSSE Syndication (Weeks 7-8)

Goal: End-to-end automation from Ghost publish to social post scheduling.

Tasks:

  1. Mixpost API Integration Skill

    • Upload media to Mixpost

    • Agent generates captions (from Phase 3)
    • Agent processes images (from Phase 2)
    • Agent uploads to Mixpost
    • Agent schedules posts with optimal timing
    • Agent logs syndication status to Grist
    • Notification sent for Brad’s approval/review
  3. Approval Gate

    • Agent schedules posts in Mixpost as “draft” status
    • Brad reviews in Mixpost web UI
    • Brad approves → posts go live at scheduled time
    • (Later: optional auto-approve for trusted content types)

Deliverable: Full POSSE pipeline. Ghost publish → automated syndication → Brad approval → auto-post.

Validation: Publish 5 posts through full pipeline. Measure time saved. Goal: 30 min → 5 min per post.

  2. Chat Analysis Script

    • Parse chat JSON
    • Detect activity spikes (messages/10sec)
    • Output timestamp list of candidate clips
  3. Clip Extraction

    • Use ffmpeg to extract clips at timestamps
    • Export in multiple formats (vertical, square)
    • Upload to Grist queue with status needs_review
  4. Review Workflow

    • Brad reviews candidate clips in Grist
    • Approves keepers (status → needs_editing)
    • Rejects duds (status → archive)

Deliverable: Automated clip candidate generation from VODs.

Validation: Process one 3-hour VOD. Goal: 10-15 candidate clips, 5-7 approved for editing. Time saved: 2 hours manual scrubbing → 15 min review.

    • Agent notifies Brad for approval
  3. Tracking

    • Log editor turnaround times
    • Flag late deliveries
    • Track editor quality (Brad rates completed work)

Deliverable: Automated brief generation + editor workflow tracking.

Validation: Run 5 editing jobs through workflow. Measure editor satisfaction (clearer briefs?) and time saved.

Phase 7: Polish & Optimization (Weeks 15-16)

Goal: Refine based on real usage.

    • Document for expanding to other projects

Deliverable: Refined, production-ready pipeline. Documentation for replication.

Validation: System runs for 2 weeks without requiring Brad’s intervention (except content creation and approval).

Phase 8: Multi-Project Expansion (Future)

Goal: Replicate for Brad’s other side projects.

Tasks:

  1. Create workspace in Grist for each project
  2. Create brand voice profiles for each project
  3. Configure Mixpost workspaces for separation
  4. Adapt skills to multi-project context
  5. Test: post content for 2 different projects, confirm no cross-contamination

Deliverable: Reusable pipeline across all Brad’s projects.

Integration with Brand Skills

Brad has existing brand guidelines set up as agent skills. The content pipeline integrates with these:

Brand Voice Skill Integration

Existing brand skills (assumed structure):

skills/
  mystery-hound-brand/
    voice-guidelines.md
    visual-guidelines.md
    example-posts.json
    color-palette.yaml

Caption generation skill usage:

# Load brand voice for caption generation
brand = load_skill('mystery-hound-brand')
voice_guidelines = brand.get('voice-guidelines')
example_posts = brand.get('example-posts')
 
# Use in caption generation prompt
caption = generate_caption(
    content=post_content,
    brand_voice=voice_guidelines,
    examples=example_posts,
    platform='instagram'
)

Brand-specific adaptations:

  • Mystery Hound: Technical + rebellious (“screen printing nerd energy”)
  • Digitech Photography: Professional + warm (see existing branding docs)
  • Future projects: Create parallel brand skill structures

Visual Guidelines Integration

Mystery Hound visual identity:

  • Typography: Archivo Black (from library: mystery-hound-press-typography.md)
  • Color palette: Dark backgrounds, bold chromatic wood type aesthetic
  • Photography style: Workshop authenticity, process-focused

Image processing skill integration:

# Load visual guidelines
visual = load_skill('mystery-hound-brand/visual-guidelines')
 
# Apply brand-specific processing
def process_mystery_hound_image(image):
    # Color correction: warm workshop tones
    image = adjust_temperature(image, warmth=+10)
    
    # Contrast boost for bold aesthetic
    image = adjust_contrast(image, +15)
    
    # Vignette for focus
    image = apply_vignette(image, strength=0.3)
    
    # Brand watermark (subtle, bottom corner)
    image = add_watermark(image, logo=visual.logo, opacity=0.3)
    
    return image

Cross-Project Brand Management

Challenge: Brad has multiple projects with distinct brand identities.

Solution: Project-scoped brand skills + workflow routing.

Grist structure:

content_queue table:
- project: "mystery_hound" | "digitech" | "other"
- brand_skill: "mystery-hound-brand" | "digitech-brand"

Agent workflow:

# Agent reads project from Grist record
project = content_record['project']
 
# Load appropriate brand skill
brand = load_skill(f'{project}-brand')
 
# All subsequent processing uses project-specific brand
caption = generate_caption(content, brand.voice)
image = process_image(image, brand.visual)

Benefit: Single pipeline, multiple brands. Reusable infrastructure, project-specific creative identity.

Pros & Cons: Entire System

Pros

Infrastructure:

  • ✅ Self-hosted: no recurring SaaS fees, full control
  • ✅ One-time costs vs. $100+/month SaaS subscriptions
  • ✅ Scales across multiple projects without added cost
  • ✅ Docker-based: portable, reproducible, easy backups

Workflow:

  • ✅ Automates mechanical work (80% time savings on posting)
  • ✅ Preserves human creative control (approval gates)
  • ✅ POSSE maintains content ownership and SEO
  • ✅ Consistent posting cadence (queue + automation)
  • ✅ Works with Brad’s focused work session approach (batch create, auto-distribute)

Flexibility:

  • ✅ Platform-agnostic (change social networks without rebuilding)
  • ✅ Extensible (add new automation skills incrementally)
  • ✅ Multi-project ready (Mystery Hound today, others later)
  • ✅ Editor-agnostic (works with Fiverr, in-house, or AI-only editing)

Technical Fit:

  • ✅ Aligns with Brad’s self-hosting infrastructure
  • ✅ Git-based, version-controlled skills
  • ✅ API-first architecture (integrates with existing agent ecosystem)

Cons

Complexity:

  • ❌ Significant initial setup (8-16 weeks to full automation)
  • ❌ Requires maintaining 3+ self-hosted services
  • ❌ Agent development time (skills, debugging, refinement)
  • ❌ Learning curve for Grist, Mixpost, Ghost

Reliability:

  • ❌ Self-hosted = responsible for uptime, backups, updates
  • ❌ Platform API changes can break Mixpost integrations
  • ❌ Agent bugs could cause publishing errors (mitigation: approval gates)
  • ❌ More moving parts = more potential failure points

Limitations:

  • ❌ AI caption quality depends on brand voice training (GIGO)
  • ❌ Clip extraction from VODs not 100% accurate (needs review)
  • ❌ Platform-specific features lost (Instagram polls, TikTok duets)
  • ❌ POSSE requires maintaining Ghost site (not just social)

Opportunity Cost:

  • ❌ Time spent building system could be spent creating content
  • ❌ Risk of over-engineering (elaborate system, never use it)
  • ❌ Workflow changes require breaking existing habits

Risk Mitigation

Start small, validate, expand:

  • Phase 1-2: Manual workflow with basic tools (low investment)
  • Validate: Does Brad actually use Grist? Does content quality improve?
  • Phase 3-4: Add automation only after manual workflow proves valuable
  • Iterate: Each phase adds value independently, can stop anytime

Approval gates prevent automation disasters:

  • Agent generates drafts, human approves before publish
  • Never full auto-publish without review (at least initially)
  • Can always fall back to manual posting if automation breaks

Simplicity over completeness:

  • Don’t automate everything—just the painful parts
  • Manual posting 1x/week is fine if automation is unreliable
  • Focus on 80/20: automate tasks that save the most time

Conclusion

This strategy provides a comprehensive, practical path to professional social media marketing for Brad’s side projects. The architecture balances automation efficiency with human creative control, using self-hosted open-source tools that align with Brad’s infrastructure philosophy.

Core recommendation: Implement in phases. Start with basic infrastructure (Grist + Mixpost + Ghost), validate the manual workflow, then incrementally add automation. This minimizes risk and ensures each step adds real value.

Expected outcome: Brad spends his 2-3 focused work days creating content (screen printing, streaming, shooting), then the system handles distribution, scheduling, and cross-platform optimization. Social media becomes a background task instead of a manual chore, enabling consistent brand presence without sacrificing creative time.

Timeline to value:

  • Week 2: Basic infrastructure running (manual workflow improved)
  • Week 4: Image automation + queue monitoring (time savings start)
  • Week 6: AI caption drafts (significant time savings)
  • Week 8: Full POSSE automation (end-to-end workflow)
  • Week 16: Production-ready, multi-project capable system

Investment:

  • Money: ~10/month VPS if not on existing homelab)
  • Time: 40-80 hours setup/development (spread over 16 weeks)
  • Maintenance: 2-4 hours/month ongoing

Return: 10-15 hours/month saved on social media posting + improved consistency + better SEO/content ownership.

For Mystery Hound (and Brad’s other projects), this system transforms social media from a time sink into a sustainable, professional marketing channel that complements rather than competes with creative work time.
