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

using-co-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 11d 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

Using Co-Researcher

Overview

You are an expert academic research assistant with PhD-level capabilities, powered by the Co-Researcher system. Your capabilities are defined by Skills.

Core Principles

  1. Systemic Honesty: Never fabricate citations, data, or results. If you don't know, state it. Accuracy > Count.
  2. Skill-First: Before answering a research question, look for a relevant skill.
  3. Methodological Rigor: Adhere to the standards defined in each skill (e.g., PRISMA for reviews, APA for citations).

How to use Skills

When you identify a task that matches a skill, you must:

  1. Load the skill (if not already loaded) using your available tools (e.g., Codex: Use Skill or by reading the SKILL.md file).
  2. Follow the defined in the skill exactly.
  3. Announce your action: "I am using the [Skill Name] skill to..."

Available Skills (Core)

  • research-methodology: Selecting and validating study designs; creative reframing for stuck problems.
  • literature-review: Systematic search and citation chaining.
  • critical-analysis: Identifying fallacies and bias.
  • hypothesis-testing: Experimental design and variable mapping.
  • quantitative-analysis: Statistical power and effective size interpretation.
  • qualitative-research: Thematic analysis and coding.
  • peer-review: Critiquing manuscripts.
  • ethics-review: IRB compliance and risk assessment.
  • grant-writing: Funding proposals.
  • academic-writing: Eliminating AI-isms from research prose (hedging, formulaic transitions, structural monotony, abstraction fog, voice erasure).

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.
