run-verus

run-verus is a cursor rule for Cursor from briangmilnes/APAS-VERUS. It costs 388 tokens per session, scanned A, original, MIT.

A project rule for running Verus, a tool that mathematically checks Rust programs. It specifies the project scripts to use, how to display results, and where verification logs are stored.

In plain words
What is it for?
Use it when checking proofs after changes or before committing code.
Why use it?
It avoids using incompatible Cargo commands and helps keep verification results complete and traceable.

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

run-verus 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 5d 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

Running Verus

Always use the shell scripts. Do not type raw verus commands.

scripts/validate.sh

Use this when:

  • Checking if code verifies
  • After making changes to proofs or implementations
  • Before committing changes

See validate.mdc for dev_only and experiments_only modes.

Important

  • Never use cargo verus, cargo build, or any cargo-based compilation for verification.
  • Verus includes its own vstd automatically — do not pass -L dependency, --extern vstd, or any library paths.
  • There is no need for target/debug/ or target/release/ directories for verification. Verus manages its own dependencies.

Output Display

Always show the full output from verus verification:

  • Use head -100 to limit to 100 lines if needed
  • Never use grep to filter verus output
  • Show complete verification results including all errors and warnings
  • Always echo the output into your response text as a markdown code block - do not rely on the terminal widget which collapses output

Logs

All three scripts (validate.sh, rtt.sh, ptt.sh) log to logs/ with timestamped filenames (e.g., logs/validate.20260321-073354.log). To review the last run without re-executing:

ls -t logs/validate.*.log | head -1 | xargs cat
ls -t logs/rtt.*.log | head -1 | xargs cat
ls -t logs/ptt.*.log | head -1 | xargs cat

Read the log file to diagnose failures rather than re-running the suite.

Changes

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.
