What it does

Database is an agent skill from championswimmer/onepixel_backend. Understand onepixel database topology by environment, data ownership across app/events stores, and initialization/migration behavior.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases. It works with PostgreSQL, DuckDB, SQLite and ClickHouse.

When your agent uses it

  • Databases work in your project

Example prompts

  • “/database”

What it can do on your machine

Read from SKILL.md and the folder at commit 033a0d3. 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

    Shell commands in SKILL.md call:

    • make

    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 loads about 810 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~810

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 315 words (~810 tokens).

“Use this skill when changing config, models, controllers, or test setup that touches persistence.”

When should I use Database?

Database fits situations like: databases work in your project.

How do I install Database in Claude Code?

Run `npx skills add championswimmer/onepixel_backend --skill database -a claude-code`. Or copy the skill folder (.agents/skills/database in championswimmer/onepixel_backend) into .claude/skills/database in your project. Claude Code loads it when a task matches its description.

How do I install Database in Codex?

Can I use Database 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 championswimmer/onepixel_backend --skill database -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, .gemini/skills/database, .github/skills/database and .opencode/skills/database in your project.

What does Database need to run?

Going by SKILL.md and its folder, Database needs the command-line tools its instructions call (make).

Does Database 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.
