What it can do on your machine
Read from SKILL.md and the folder at commit 75e1158. 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
Ships script files (Shell), which the agent can run.
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
Database Design loads about 1.1k tokens when it runs. Until then it costs about 7 tokens; SKILL.md has 169 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.
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.

Questions about Database Design
How do I install Database Design in Claude Code?
Run `npx skills add Leavesfly/Jimi --skill database-design -a claude-code`. Or copy the skill folder (src/main/resources/skills/database-design in Leavesfly/Jimi) into .claude/skills/database-design in your project. Claude Code loads it when a task matches its description.
How do I install Database Design in Codex?
Run `npx skills add Leavesfly/Jimi --skill database-design -a codex`. Or copy the skill folder (src/main/resources/skills/database-design in Leavesfly/Jimi) into .agents/skills/database-design in your project. Codex loads it when a task matches its description.
Can I use Database Design in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Leavesfly/Jimi --skill database-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/database-design, .gemini/skills/database-design, .github/skills/database-design and .opencode/skills/database-design in your project.
What does Database Design need to run?
Going by SKILL.md and its folder, Database Design needs a shell for the scripts in its folder.
Does Database Design access the network?
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.
Is Database Design safe to install?
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.
What licence does Database Design use?
No licence was found for Database Design or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Database Design use?
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Database Design?
Skills that share tags, products or a category with Database Design: SQL Optimization Patterns (ynulihao/AgentSkillOS, 617 stars), Add Mpk Task (mirage-project/mirage, 2.5k stars), B200 Flash Attention4 Planner (mirage-project/mirage, 2.5k stars) and Experiment Audit (wanshuiyin/Auto-claude-code-research-in-sleep, 17k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Database Design?
Leavesfly (a GitHub user) maintains it in Leavesfly/Jimi, which has 237 GitHub stars. The repository holds 9 skills in this directory. The repository was last updated on August 19, 2026.
