# DeepSec — agent-powered deep security audit
[deepsec](https://github.com/vercel-labs/deepsec) by Vercel Labs (Apache-2.0,
~700 stars). Wraps coding agents at maximum thinking levels to find:
- subtle auth-bypass paths
- TOCTOU race conditions
- crypto misuse (custom IV, key reuse)
- SSRF in user-controllable URL handlers
- prototype pollution, ReDoS in dynamic regex
- vulnerable dep transitive paths static SAST misses
Distinct from `daily-supply-chain-audit` (which is dep-tree CVE scanning).
DeepSec reads YOUR code semantically.
## When to invoke
| Trigger | Example |
|---|---|
| Pre-launch deep audit | "Run deepsec on [project-a] before going to mainnet" |
| Post-incident root cause | "Scan [company]-rpc for the auth-bypass class we just patched" |
| Periodic deep dive | "Quarterly deepsec on [project-b]" |
| Specific concern | "Deepsec the new Solana program in anchor-vault" |
DO NOT run automatically. DO NOT run on every PR (cost). DO confirm
budget before kicking off.
## Cost reality
Per the project's own README: scans can cost **thousands of dollars** for
large repos because they fan out parallel workers at maximum reasoning
depth.
**Walter-OS budget guardrail**:
- Confirm $ before any scan
- Use scoped repos (small components, not monorepos)
- Default model tier: Opus or GPT-5.5-pro (cheaper than maximum)
- Cap fan-out workers at 2 unless operator overrides
## Setup (per repo, one-time)
```bash
cd ~/Projects-Personal/<repo> # or ~/work/<repo>
npx deepsec
