client-generator-agent

client-generator-agent is an agent for Claude Code from TheLobbi/claude. It costs 31 tokens per session (1,578 once invoked), scanned A, original, MIT.

An API client code generator that turns endpoint schemas into typed code for calling a web service. It creates request building, response parsing, error handling, pagination, batches, and webhook verification helpers.

In plain words
What is it for?
Use it to create a client class, resource methods, request builders, response wrappers, interceptors, pagination helpers, batch requests, configuration types, and usage examples.
Why use it?
It avoids hand-writing repetitive code for each API endpoint and keeps client methods aligned with the API description. Typed requests and responses make incorrect data shapes easier to spot while coding.

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

client-generator-agent 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 2d 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.

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.
