repro-api

repro-api is an agent for coding agents from EngDawood/emdash-claude-plugin. It costs 48 tokens per session (1,139 once invoked), scanned A, original, no licence file.

A bug-reproduction workflow for problems below the browser layer, such as REST handlers, command-line tools, MCP, database migrations, schemas, or build tools. It prefers recording the problem in a failing Vitest test; Vitest is a JavaScript testing tool.

In plain words
What is it for?
It is for reproducing failures in server code, command-line interfaces, migrations, schema systems, MCP integrations, and build tooling.
Why use it?
It separates backend and tooling bugs from browser problems and leaves a repeatable test showing the failure.

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

repro-api scanned grade A with 1 finding 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.

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.
