$ npx skills add tech-leads-club/agent-skills --skill component-common-domain-detection -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install tech-leads-club/agent-skills component-common-domain-detection --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/tech-leads-club/agent-skills.git skills-src && mkdir -p .claude/skills && cp -r skills-src/'packages/skills-catalog/skills/(architecture)/component-common-domain-detection' .claude/skills/component-common-domain-detection && rm -rf skills-src

At a glance

Finds duplicate business logic spread across multiple components and suggests consolidation.

  • Works in 5 steps: Identify Common Namespace Patterns → Detect Shared Classes → Analyze Functionality Similarity → …
  • Asking where is this logic duplicated?
  • SKILL.md covers How to Use, When to Use, Core Concepts and Analysis Process, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Component Common Domain Detection is an agent skill from tech-leads-club/agent-skills. Finds duplicate business logic spread across multiple components and suggests consolidation. Use when asking "where is this logic duplicated?", "find common code between services", "what can be consolidated?", "detect shared domain logic", or analyzing component overlap before refactoring. Do NOT use for code-level duplication detection (use linters) or dependency analysis (use coupling-analysis).

Its SKILL.md is about 4.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `QUICK-REFERENCE.md` and `README.md`).

It sits in Development, covering Linting and formatting and Refactoring. The repository describes itself as: The secure, validated skill registry for professional AI coding agents. Extend Antigravity, Claude Code, Cursor, Copilot and more with absolute confidence.

When your agent uses it

  • Asking where is this logic duplicated?
  • Find common code between services
  • What can be consolidated?
  • Detect shared domain logic

Example prompts

  • “where is this logic duplicated?”
  • “find common code between services”
  • “what can be consolidated?”
  • “/component-common-domain-detection”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify Common Namespace Patterns
  2. Detect Shared Classes
  3. Analyze Functionality Similarity
  4. Assess Coupling Impact
  5. Recommend Consolidation Approach

What it can do on your machine

Read from SKILL.md and the folder at commit 6df68d5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and javascript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Component Common Domain Detection loads about 4.3k tokens when it runs. Until then it costs about 109 tokens; SKILL.md has 1,079 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~4.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,079 words (~4,344 tokens).

“This skill identifies common domain functionality that is duplicated across multiple components and suggests consolidation opportunities to reduce duplication and improve maintainability.”
