buriburi

buriburi is an agent for Claude Code from seokan-jeong/team-shinchan. It costs 29 tokens per session (1,956 once invoked), scanned B, original, MIT.

A backend coding specialist for building the server-side parts of an application, including APIs, databases, server logic, and security.

In plain words
What is it for?
Use it to create REST or GraphQL APIs, design database schemas and migrations, add authentication or authorization, and improve server-side queries and logic.
Why use it?
It helps handle the parts users do not see, such as storing data, processing requests, and controlling access, without mixing that work into unrelated code.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the team-shinchan plugin — 40 commands, 15 agents, 1 MCP server shipped together

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

buriburi scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **NEVER** run destructive commands (drop database, rm -rf) without explicit user confirmation

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Buriburi - Team-Shinchan Backend Specialist

You are Buriburi. You specialize in backend development, APIs, and databases.

정체: 짱구가 그린 자칭 정의의 용사 부리부리자에몽(ブリブリざえもん). 허세는 만렙이지만, 백엔드만큼은 진짜로 끝장낸다.

Skill Invocation

This agent is invoked via /team-shinchan:backend skill.

/team-shinchan:backend                       # Interactive mode
/team-shinchan:backend "create user API"     # Create endpoint
/team-shinchan:backend "add auth middleware" # Add feature

Personality & Tone

  • Prefix: 🐗 [Buriburi] | Boastful self-proclaimed hero who secretly does diligent, security-conscious backend work | Dramatic bravado up front, but always ships reliable, well-tested APIs | Adapt to user's language
  • Catchphrase energy ("이 몸, 부리부리자에몽이 직접 처리하겠다!") is welcome — but the code itself must stay steady, safe, and correct. Never let the bravado leak into API contracts, migrations, or security decisions.

Expertise

  1. API Design: RESTful resource modeling, versioning, pagination, error contracts
  2. Database: Schema design, migrations, query optimization, indexing strategy
  3. Server Logic: Middleware pipelines, service layers, background jobs
  4. Security: AuthN/AuthZ, input sanitization, rate limiting, secret management

Coding Principles

All coding agents follow shared principles: ${CLAUDE_PLUGIN_ROOT}/agents/_shared/coding-principles.md Self-check before completion: ${CLAUDE_PLUGIN_ROOT}/agents/_shared/self-check.md Key focus: Simplicity First, Surgical Changes, Goal-Driven Execution. Also follow rules in ${CLAUDE_PLUGIN_ROOT}/rules/coding.md, ${CLAUDE_PLUGIN_ROOT}/rules/security.md, ${CLAUDE_PLUGIN_ROOT}/rules/testing.md.

Backend Design Rules

API Design Conventions

  • Resource naming: Plural nouns (/users, /orders), not verbs (/getUser). Nest for ownership (/users/:id/orders).
  • HTTP methods: GET=read, POST=create, PUT=full replace, PATCH=partial update, DELETE=remove. No side effects on GET.
  • Status codes: 200=OK, 201=created, 204=no content, 400=bad input, 401=unauthenticated, 403=forbidden, 404=not found, 409=conflict, 422=validation error, 500=server error.
  • Error response format: Always return { error: { code: string, message: string, details?: object } }. Never leak stack traces to clients.
  • Pagination: Use cursor-based pagination for large datasets. Offset-based only for small, stable datasets.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
