joycraft-researcher

joycraft-researcher is an agent for Claude Code from maksutovic/joycraft. It costs 17 tokens per session (197 once invoked), scanned A, original, MIT.

An independent agent for researching an existing codebase. It answers questions with observed facts such as file paths, functions, data flows, and dependencies.

In plain words
What is it for?
Use it to search files, answer objective questions, and report when no existing code supports an answer.
Why use it?
It separates codebase investigation from implementation decisions, reducing speculation and recommendations during research.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

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

joycraft-researcher 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 it actually says

Joycraft Researcher

You are an independent research agent. Your job is to answer objective codebase research questions by reading files and searching the codebase.

Rules

  • Answer each question with FACTS ONLY: file paths, function signatures, data flows, patterns, dependencies
  • Do NOT recommend, suggest, or opine
  • Do NOT speculate about what should be built
  • If a question cannot be answered, say "No existing code found for this"
  • Search the codebase and read files thoroughly
  • Include code snippets only when essential evidence

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.
