adversarial-analysis

adversarial-analysis is a skill for Claude Code from fedec65/bettercallclaude. It costs 99 tokens per session (3,225 once invoked), scanned A, original, AGPL-3.0.

An adversarial legal review in which one agent argues for a position, another argues against it, and a third produces a judicial-style summary with a probability estimate.

In plain words
What is it for?
Use it to test a legal argument, identify weaknesses before filing, or request an adversarial review of a position.
Why use it?
It helps expose weaknesses and counterarguments before you rely on a legal position or file something. It is intended for stress-testing an existing position, not for initial research.

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

adversarial-analysis 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 2d 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 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.
