Clinkding - Linkding Bookmark Integration

Manage linkding bookmarks - save URLs, search, tag, organize, and retrieve your personal bookmark collection. Use when the user wants to save links, search bookmarks, manage tags, or organize their reading list.

Security Scan

The skill appears to match its stated purpose (wrapping the clinkding CLI for a linkding instance) but the runtime instructions reference credentials, config paths, and file uploads that are not declared in the metadata — a minor coherence issue that users should review before installing.

Purpose & Capability

Name, description, required binary (clinkding), and install methods (Homebrew / Go) align with a CLI wrapper for the linkding bookmark service. The homepage points to a matching GitHub repo, and the commands in SKILL.md are consistent with a bookmark-management CLI.

Instruction Scope

SKILL.md stays within the expected scope of managing bookmarks (create/list/update/delete tags, bundles, assets, etc.). It does instruct the agent to read/write the clinkding config (~/.config/clinkding/config.yaml), honor LINKDING_URL/LINKDING_TOKEN env vars, and to upload local files as assets — all expected for this tool, but worth noting because the agent may read local files or send conversation text as bookmark descriptions.

Install Mechanism

Install methods are Homebrew formula and Go module (building a Go binary). Both are standard and proportionate for a Go-based CLI; no arbitrary download URLs or extraction steps are present.

Credentials

Metadata declares no required environment variables or primary credential, but the SKILL.md explicitly documents LINKDING_URL and LINKDING_TOKEN and a config file containing a token. The skill will need an API token to contact a linkding instance; that credential is not declared in the registry metadata, which is an inconsistency users should verify before granting access.

Persistence & Privilege

Skill is not always-included and does not request elevated platform-wide privileges. The install creates a single CLI binary (expected). The skill does instruct writing/reading its own config file in the user's home (~/.config/clinkding), which is normal for a CLI but means the agent may store credentials there.

What to consider before installing

This skill is a CLI wrapper for the clinkding tool and is generally coherent with that purpose, but review these points before installing: - The SKILL.md expects LINKDING_URL and LINKDING_TOKEN (or a config file at ~/.config/clinkding/config.yaml) even though the registry metadata lists no required env vars — confirm you will supply a token and understand where it will be stored. - The agent may be instructed to upload local files (assets). Only allow the skill/agent to access files you are comfortable sending to your linkding instance. - Verify the Homebrew formula / Go module source (the provided homepage repo) is the legitimate project you expect. - Consider using a least-privilege API token for linkding (limited scope or a dedicated account) rather than a broad personal token. If you prefer, ask the skill provider to update the registry metadata to declare LINKDING_TOKEN (and LINKDING_URL) so the credential requirements are explicit.

clinkding - Linkding Bookmark Manager CLI

A modern Go-based CLI for managing bookmarks in linkding, a self-hosted bookmark manager.

What This Does

Linkding is a self-hosted bookmark manager (like Pocket, Instapaper). clinkding is the CLI that lets you manage your bookmarks from the terminal or via AI agents.

Think of it as:

• Save for later - Capture URLs you want to read
• Searchable library - Full-text search across titles, descriptions, tags
• Organized collections - Tag and bundle related bookmarks
• Personal archive - Keep important links with notes and metadata

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

1. Always fetch metadata - Use summarize to get good titles/descriptions
2. Use existing tags - Never create new tags without checking canonical list
3. Be selective - 2-5 tags max, choose the most specific applicable
4. Validate first - Check for duplicates before creating
5. 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.
