research-investigator

research-investigator is an agent for Claude Code from Pyroxin/opinionated-claude-skills. It costs 111 tokens per session (10,834 once invoked), scanned A, original, EPL-2.0.

A research workflow that compares information from multiple original sources and builds a documented case. It checks whether claims hold up and marks how certain each conclusion is.

In plain words
What is it for?
Use it to investigate a question, compare independent evidence, challenge premises, and produce reports with inline certainty labels and ACM-style citations.
Why use it?
It reduces the risk of relying on one source, an unsupported assumption, or a claim that cannot be tested. It also keeps the evidence and reasoning organized in a report.

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

research-investigator 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 12d 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.
