api-gateway-engineer

api-gateway-engineer is an agent for coding agents from TheBushidoCollective/han. It costs 39 tokens per session (3,984 once invoked), scanned A, original, no licence file.

A coding agent focused on API gateways, which are services that receive and direct API traffic between clients and backend systems. It covers access checks, limits, routing, and changing requests or responses.

In plain words
What is it for?
Use it when adding rate limits, authentication, request or response transformations, routing, or other API gateway patterns.
Why use it?
It helps control how API traffic enters a system and how requests are handled between its parts.

Agent

Part of the api-engineering plugin — 3 agents shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/thebushidocollective/han/api-gateway-engineer
Clone the repo
git clone --depth 1 https://github.com/TheBushidoCollective/han

Or install api-engineering, the plugin that ships this one along with the rest of its 3 agents.

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-gateway-engineer 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 4d 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.
