Agent Workflows for Smart Bookmark Creation

Adding URLs with Automatic Metadata

When a user says "Add this to linkding" or "Save this URL", follow this workflow:

1. Extract metadata from the URL

Use the summarize skill to get title and description:

# Get page metadata
summarize url https://example.com --format json

This returns structured data with:

Title
Description/summary
Main content

2. Infer appropriate tags from content

Map the content to existing canonical tags only. Do NOT create new tags.

Use this canonical tag list (263 tags total):

Tech: webdev, design, programming, ai, cloud, devops, docker, linux, networking, security, privacy
Content: content, media, photography, video, audio, books, podcasting
Business: business, marketing, ecommerce, finance, career, productivity
Home: smart-home, home-assistant, esphome, iot, home-improvement
Tools: tools, cli, git, github, editor, reference, documentation
Data: data, analytics, mysql, nosql
Communication: communication, email, messaging, slack
Education: education, guide, howto, research, testing
Locations: texas, seattle, dallas (use sparingly)

Tag Selection Rules:

Use 2-5 tags maximum
Choose the most specific applicable tags
If unsure, default to broader categories (e.g., tools over generator)
Check existing tags first: clinkding tags list --plain | grep -i <keyword>
Never create tags like: awesome, cool, interesting, resources, tips

3. Create the bookmark with metadata

clinkding bookmarks create "https://example.com" \
  --title "Title from summarize" \
  --description "Summary from summarize (1-2 sentences)" \
  --tags "webdev,tools,reference"

Example Workflow

User: "Save this to linkding: https://github.com/awesome/project"

Agent Actions:

# 1. Check if already bookmarked
clinkding bookmarks check https://github.com/awesome/project

# 2. Get metadata (use summarize skill)
summarize url https://github.com/awesome/project --format json

# 3. Analyze content and infer tags
# From summary: "A CLI tool for Docker container management"
# Canonical tags: docker, devops, cli, tools

# 4. Create bookmark
clinkding bookmarks create https://github.com/awesome/project \
  --title "Awesome Project - Docker Container CLI" \
  --description "Command-line tool for managing Docker containers with enhanced features" \
  --tags "docker,devops,cli"

Tag Mapping Heuristics

Use these rules to map content → canonical tags:

Content Type	Canonical Tags
Web development, HTML, CSS, JavaScript	`webdev`, `css`, `javascript`
React, frameworks, frontend	`webdev`, `react`
Design, UI/UX, mockups	`design`
Python, Go, Ruby code	`programming`, `python`/`ruby`
Docker, K8s, DevOps	`docker`, `devops`, `cloud`
Home automation, ESP32, sensors	`smart-home`, `esphome`, `iot`
AI, ML, LLMs	`ai`, `llm`
Productivity tools, workflows	`productivity`, `tools`
Finance, investing, crypto	`finance`
Marketing, SEO, ads	`marketing`
Shopping, deals, stores	`ecommerce`
Tutorials, guides, docs	`guide`, `howto`, `documentation`
Security, privacy, encryption	`security`, `privacy`
Local (DFW/Seattle)	`texas`, `seattle`

Validation Before Creating

Always run these checks:

# 1. Does URL already exist?
clinkding bookmarks check <url>

# 2. Do the tags exist?
clinkding tags list --plain | grep -iE "^(tag1|tag2|tag3)$"

# 3. Are we using canonical tags?
# Cross-reference against the 263 canonical tags
# Never create new tags without explicit user request

User Requests to Save Multiple Links

If user provides multiple URLs:

# Process each URL separately with metadata extraction
for url in url1 url2 url3; do
  # Get metadata
  # Infer tags
  # Create bookmark
done

Updating Existing Bookmarks

If user says "Update that bookmark" or "Add tags to my last save":

# Get most recent bookmark
recent_id=$(clinkding bookmarks list --limit 1 --plain | cut -f1)

# Add tags (don't remove existing ones unless asked)
clinkding bookmarks update $recent_id --add-tags "new-tag"

# Update description
clinkding bookmarks update $recent_id --description "Updated notes"

Key Principles

Always fetch metadata - Use summarize to get good titles/descriptions
Use existing tags - Never create new tags without checking canonical list
Be selective - 2-5 tags max, choose the most specific applicable
Validate first - Check for duplicates before creating
Provide context - Include brief description explaining why it's useful

Current Canonical Tag Structure

Dave's linkding instance has 263 canonical tags after consolidation from 17,189 duplicates.

Top categories (by bookmark count):

pinboard (4,987) - Legacy import tag
ifttt (2,639) - Legacy import tag
webdev (1,679) - Web development
design (561) - Design/UI/UX
content (416) - Content/writing
cloud (383) - Cloud/hosting/SaaS
business (364) - Business/strategy
ecommerce (308) - Shopping/marketplace
smart-home (295) - Home automation
productivity (291) - Productivity tools

Golden Rule: When in doubt, use broader existing tags rather than creating new specific ones.
