repoforge: Skill for Claude Code

.claude/skills/frontend/types/SKILL.md

add-types-endpoint is a skill for Claude Code from JNZader/repoforge. It costs 30 tokens per session (564 once invoked), scanned A, original, MIT.

A guide for defining the data types used by generation requests. A data type describes the fields and allowed values that a program expects, such as a user record or a generation mode.

In plain words
What is it for?
Use it to define user structures and specify generation modes when working on generation requests.
Why use it?
It makes request data more predictable and documents how users and generation choices are represented in code.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is JNZader/repoforge's own configuration. It tells Claude Code how to work on repoforge 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 repoforge configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python repoforge/cli.py --help.

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

add-types-endpoint scanned grade A with 0 findings 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 24d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

add-types-endpoint

Type-safe frontend types for generation workflows and SSE events.

Trigger: when adding new generation types or events to the frontend.

Quick Reference

Task Pattern
Validate user login User
Create generation request GenerateRequest

Critical Patterns (Summary)

  • User Pattern: Validates github_user_id and login from User interface
  • GenerationRequest Pattern: Constructs GenerateRequest with required repo_url, mode, and provider

Critical Patterns (Detailed)

User Pattern

Validates github_user_id and login from User interface to ensure authenticated session state before initiating generation workflows.

import { User } from '@/lib/types';

if (!User || !User.github_user_id) {
  throw new Error('User not authenticated');
}

GenerationRequest Pattern

Constructs GenerateRequest with required repo_url, mode, and provider fields to start a new generation pipeline.

import { GenerateRequest } from '@/lib/types';

const request: GenerateRequest = {
  repo_url: 'https://github.com/example/repo',
  mode: 'skills',
  provider: 'openai',
};

When to Use

  • Validating authenticated user session before generation
  • Constructing generation requests with proper mode and provider selection
  • Handling user authentication state in generation workflows

Commands

docker build -t repoforge/app:latest .
python repoforge/cli.py --help

Anti-Patterns

Don't: Missing required fields in GenerateRequest

<Why it's wrong: Omitting repo_url, mode, or provider causes runtime errors during generation pipeline initialization. All three fields are required per the GenerateRequest interface definition.>

import { GenerateRequest } from '@/lib/types';

const badRequest: GenerateRequest = {
  // Missing repo_url, mode, provider — will fail validation
  mode: 'skills',
};

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.

add-types-endpoint is a skill published in the GitHub repository JNZader/repoforge (5 stars, last pushed 24d ago), licensed MIT. It adds 30 tokens to every session and 564 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
