forgecraft-mcp: Agent for Claude Code

.claude/agents/test-hunter.md

test-hunter is an agent for Claude Code from jghiringhelli/forgecraft-mcp. It costs 83 tokens per session (631 once invoked), scanned A, original, no licence file.

An agent that creates adversarial tests for a module or feature. It looks for inputs that break rules, bypass permissions, cause timing problems, or violate stated conditions.

In plain words
What is it for?
Use it to harden an existing test suite by checking security boundaries, race conditions, input handling, and other module contracts.
Why use it?
It helps find failures that normal happy-path tests often miss before sensitive code is merged.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is jghiringhelli/forgecraft-mcp's own configuration. It tells Claude Code how to work on forgecraft-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything forgecraft-mcp configures →

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

test-hunter 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 1mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
