service-builder

service-builder is an agent for Claude Code from nchdatta/projectkit. It costs 42 tokens per session (1,102 once invoked), scanned A, original, no licence file.

A coding agent that connects a finished API endpoint to a client application. It covers the data types, service functions, and TanStack Query hooks and keys used to request and cache data.

In plain words
What is it for?
Use it to expose an existing API endpoint in the client, including entity types, service methods, query hooks, mutation hooks, and query keys.
Why use it?
It removes the repeated wiring work between a server endpoint and the user interface. It also keeps related client-side request code in the designated service and hook areas.

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

service-builder 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.

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.
