sddp-api-designer

sddp-api-designer is an agent for Claude Code from attilaszasz/sdd-pilot. It costs 21 tokens per session (56 once invoked), scanned A, original, MIT.

An agent that generates API contracts, which formally describe how software interfaces exchange data, using formats such as OpenAPI or GraphQL.

In plain words
What is it for?
Use it to design and document REST or GraphQL APIs from project feature requirements.
Why use it?
It helps turn a feature design into a shared, precise description of endpoints, inputs, outputs, and types before implementation begins.

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

sddp-api-designer 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 9d 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.
