Modular Design Principles is an agent skill from tech-leads-club/agent-skills. Technology-agnostic guidance for modular systems: bounded contexts, clear boundaries, composability, state isolation, explicit contracts, failure containment, scaffolding workflows, split/merge criteria, sub-units inside a context, and compliance review signals. Use when designing or reviewing module structure, service boundaries, package layout, cross-cutting dependencies, "how should we split this?", modularity assessments, coupling between domains, greenfield context design, or architecture discussions without…
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/principles.md`).
It sits in Development, covering Domain-driven design, Project scaffolding and Microservices. 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.
8 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 6df68d5. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Modular Design Principles loads about 3.1k tokens when it runs, and up to ~4.8k if it reads all its reference files. Until then it costs about 225 tokens; SKILL.md has 1,462 words of instructions outside code blocks.
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.
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.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,462 words (~3,078 tokens).
“Use this skill when reasoning about structure and boundaries in any codebase. It intentionally avoids framework names, folder conventions, and tooling — map principles to your stack locally.”

Technology-agnostic guidance for modular systems: bounded contexts, clear boundaries, composability, state isolation, explicit contracts, failure containment, scaffolding workflows, split/merge…. Modular Design Principles is an agent skill from tech-leads-club/agent-skills. Technology-agnostic guidance for modular systems: bounded contexts, clear boundaries, composability, state isolation, explicit contracts, failure containment, scaffolding workflows, split/merge criteria, sub-units inside a context, and compliance review signals.
Modular Design Principles fits situations like: reviewing module structure; service boundaries; cross-cutting dependencies; how should we split this?.
Run `npx skills add tech-leads-club/agent-skills --skill modular-design-principles -a claude-code`. Or copy the skill folder (packages/skills-catalog/skills/(architecture)/modular-design-principles in tech-leads-club/agent-skills) into .claude/skills/modular-design-principles in your project. Claude Code loads it when a task matches its description.
Run `npx skills add tech-leads-club/agent-skills --skill modular-design-principles -a codex`. Or copy the skill folder (packages/skills-catalog/skills/(architecture)/modular-design-principles in tech-leads-club/agent-skills) into .agents/skills/modular-design-principles in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tech-leads-club/agent-skills --skill modular-design-principles -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/modular-design-principles, .gemini/skills/modular-design-principles, .github/skills/modular-design-principles and .opencode/skills/modular-design-principles in your project.
SKILL.md names no scripts, command-line tools or credentials: Modular Design Principles is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Modular Design Principles has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 3.1k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.7k tokens, read only when the agent opens those files.
