bento: Skill for Claude Code

.claude/skills/contribute-stack/SKILL.md

contribute-stack is a skill for Claude Code from felipefontoura/bento. It costs 110 tokens per session (3,572 once invoked), scanned A, original, MIT.

A contributor guide for adding an application stack to the Bento repository. An application stack is the files needed to run an app, such as a Docker Compose configuration and metadata.

In plain words
What is it for?
Use it to scaffold a new stack under Bento’s stacks directory, optionally add a skill for operating the app through its API, update the documentation, and create a git commit.
Why use it?
It prevents contributors from adding files in the wrong project or using the contributor workflow when they actually need to deploy an app remotely. It also checks the repository’s rules before changes are made.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md; mentions Claude Code.

This is felipefontoura/bento's own configuration. It tells Claude Code how to work on bento itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything bento configures →

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 A, and why

contribute-stack scanned grade A 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 344 lines — stays where its author put it; the contents beside it link to each section on GitHub.

contribute-stack

Use this skill when a CONTRIBUTOR asks to add a new application stack to the bento repo. Always start by reading CLAUDE.md for current conventions — prefer its rules over anything stated here if they ever drift.

Context guard — check before doing anything. This skill operates on a local clone of the bento repo: it creates files under stacks/, edits README.md, and makes a git commit. Confirm you are in that context — CLAUDE.md and a stacks/app/ directory must exist in the working tree:

test -f CLAUDE.md && test -d stacks/app && echo BENTO_REPO_OK

If that fails, STOP. This is a contributor skill, not an operator one. The user is probably trying to deploy an app onto their own VPS — point them at the bento plugin's /bento:deploy skill, which does it over SSH without a local clone. Do not try to scaffold files outside a bento checkout.

Every comment, message, and doc you produce must be in English. Even when the user prompts you in Portuguese, the artifacts going into the repo stay English-only.

When to invoke

Trigger phrases include:

  • "add a new stack for "
  • "I want to bundle into bento"
  • "create a stack: "
  • "scaffold "

If the user is just asking to deploy an existing stack via the menu, that is not this skill — point them at Step 3 in the install menu.

Required inputs

Ask for these up front if missing:

  1. Stack key — short, kebab-case, lowercase (e.g. n8n, cli-proxy-api). Will be the directory name and the user-visible label in the menu.
  2. Upstream GitHub repo — <owner>/<repo> (e.g. n8n-io/n8n). This is non-negotiable: the skill fetches the project's own reference docker-compose.yml and .env.example before writing anything.
  3. Public-facing host — does this app expose an HTTP UI/API behind Traefik? If yes, the default host pattern is <key>.${BASE_DOMAIN}. If no, no Traefik labels are needed.

Everything else (image tag, env vars, secrets, dependencies, ports, healthcheck endpoint) is derived from the upstream repo in step 1 below — do not invent any of it from training data.

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.
