bayes-platform: Skill for Claude Code

.claude/skills/crud-generator/SKILL.md

crud-generator is a skill for Claude Code from bayesimpact/bayes-platform. It costs 50 tokens per session (6,504 once invoked), scanned A, original, MIT.

A generator for standard create, read, update, and delete files from an existing database entity. CRUD means creating, viewing, changing, and deleting records.

In plain words
What is it for?
Use it to generate NestJS API files and React/Redux frontend files for selected entity operations, including end-to-end tests.
Why use it?
It avoids repeatedly writing the same server and web code for a new entity and keeps the generated pieces consistent.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution. Also seen: reads .claude/ paths.

This is bayesimpact/bayes-platform's own configuration. It tells Claude Code how to work on bayes-platform 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 bayes-platform configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import type { ContextResolver, ResolvableRequest } from "../context-resolver.interface".

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

crud-generator 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 540 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate all CRUD-related files for a new feature based on an existing entity file and a selected list of operations.

Invocation format

The user provides:

  1. Entity file path — absolute or repo-relative path to the existing .entity.ts file (e.g. apps/api/src/domains/widgets/widget.entity.ts)
  2. Methods — a comma- or space-separated list of operations to generate: Create, GetAll, GetOne, Update, Delete

Example invocations:

/crud-generator apps/api/src/domains/widgets/widget.entity.ts Create GetAll Update Delete
/crud-generator entity=apps/api/src/domains/widgets/widget.entity.ts methods=Create,Update

Parse the entity file path and method list from $ARGUMENTS.

Step 1 — Parse inputs

Extract:

  • entityFilePath — the provided entity file (e.g. apps/api/src/domains/widgets/widget.entity.ts)
  • methods — the list of requested operations (default to all four if none are given: Create, GetAll, Update, Delete)
  • Derive names:
    • featureName = folder name (e.g. widgets)
    • entityName = PascalCase singular (e.g. Widget)
    • entityNamePlural = camelCase plural (e.g. widgets)
    • entityNameKebab = kebab-case singular (e.g. widget)
    • entityNameKebabPlural = kebab-case plural (e.g. widgets)
    • routePrefix = the URL segment (e.g. widgets)
    • featureDir = directory of the entity file (e.g. apps/api/src/domains/widgets/)
    • webFeatureDir = apps/web/src/features/{entityNameKebabPlural}/
    • contractsDir = packages/api-contracts/src/{entityNameKebabPlural}/

Step 2 — Read the entity file and reference examples

Read these files to understand the entity shape and codebase patterns before generating anything:

# Entity to scaffold from (user-provided)
{entityFilePath}

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.
