FastGPT: Skill for Claude Code

.agents/skills/system/api-development/SKILL.md

api-development is a skill for Claude Code, Codex from labring/FastGPT. It costs 57 tokens per session (6,369 once invoked), scanned A, original, no licence file.

An API development guide for FastGPT services. It standardizes input and output checks with Zod, documents routes in OpenAPI, and validates requests in API routes.

In plain words
What is it for?
Use it when adding or changing FastGPT API routes, request fields, response fields, or OpenAPI documentation.
Why use it?
It helps prevent unclear API contracts and invalid data from reaching route handlers. It also keeps the API documentation aligned with the code.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is labring/FastGPT's own configuration. It tells Claude Code and Codex how to work on FastGPT 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 FastGPT 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

api-development 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 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.

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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
