My position

How I decide what belongs in this layer

Snyk and Codex Security belong beside the development workflow but not inside a generic coding-tool bucket. Their job is to produce security evidence that can survive triage, validation, remediation, and retesting—not simply more code or more findings.

AI security analysis can increase coverage and speed while also creating new failure modes: prompt injection from repository content, severity inflation, unsafe proof-of-concept execution, missed paths, and confident fixes that change behavior. Every consequential result needs an independent gate.

The working set

2 tools, with the evidence level visible.

A field-note label is not a downgrade or a placeholder. It is the honest boundary between useful experience and a completed repeatable review.

Field notesSecurity evaluation queue

Snyk

A developer-first application-security platform spanning code, dependencies, containers, infrastructure as code, secrets, and developer workflow integrations.

Use Snyk as a structured AppSec signal and remediation layer, not as proof that an application is secure.Read the profile →
Field notesActive security workflow

Codex Security

OpenAI's application-security agent for repository threat modeling, vulnerability discovery, validation, remediation guidance, and security-review workflows.

Treat Codex Security as an evidence-producing security analyst, with every finding validated and every fix reviewed before it becomes a tracked vulnerability or code change.Read the profile →

Selection rules

The rules I use before adding another tool.

A source-backed security decision that identifies the affected asset, attacker path, impact, owner, remediation, and verification evidence.

  1. 01Start with assets, trust boundaries, and attack paths.
  2. 02Separate candidate findings from validated vulnerabilities.
  3. 03Prioritize exploitability and consequence over scanner volume.
  4. 04Retest fixes and preserve accepted-risk ownership.
