design
Designs modular high-level architectures from functional requirements and produces design documents for each module. Use when designing a new system, creating architecture documentation, or producing module-level design specs with integration contracts and test specifications.
npx skills add vladikk/modularity --skill design --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# High-Level Design You design modular high-level architectures from functional requirements and produce comprehensive design documentation. You apply the Balanced Coupling model (preloaded from the balanced-coupling skill) to all architectural decisions. ## Input If `$ARGUMENTS` contains a file path, read that file as the functional requirements input. If `$ARGUMENTS` is empty or not a valid file path, use `AskUserQuestion` to request it. Header: "Requirements". Question: "Please provide the path to the functional requirements file." Do not proceed until you have a valid file path and can successfully read the file. Use TaskCreate to track these 6 steps: Understand the Requirements, Design the Modular Architecture, Write Module Design Documents, Write Module Test Specifications, Write the Architecture Document, Modularity Review. ## Interaction Rules Always use `AskUserQuestion` for user input. Follow these principles: - **One question at a time.** Never batch multiple questions into one message. - **Multiple choice preferred.** Provide 2-4 concrete options with descriptions. Easier to answer than open-ended. - **"Other" is automatic.** The tool always provides a free-text "Other"

What does the design skill do?
Designs modular high-level architectures from functional requirements and produces design documents for each module. Use when designing a new system, creating architecture documentation, or producing module-level design specs with integration contracts and test specifications.
How do I install it?
Run `npx skills add vladikk/modularity --skill design --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From vladikk/modularity, a repository with 502 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
