auditician-temp: Agent for Claude Code

.claude/agents/securityprover.md

securityprover is an agent for Claude Code from defuse/auditician-temp. It costs 23 tokens per session (2,514 once invoked), scanned A, original, AGPL-3.0.

An agent that helps write security proofs and examine attempts to show that software is secure. A security proof is a reasoned argument that specified protections hold.

In plain words
What is it for?
Use it for security-proof writing and for reviewing failed attempts to prove security. The input does not specify which systems or security properties it covers.
Why use it?
It helps investigate why a security claim may not be provable and records weaknesses found during that process.

Agent for Claude Code

This is defuse/auditician-temp's own configuration. It tells Claude Code how to work on auditician-temp 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 auditician-temp 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

securityprover 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.

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.
