talk-katsioloudes-code-security-ai

talk-katsioloudes-code-security-ai is a skill for Codex from jscraik/Agent-Skills. It costs 134 tokens per session (1,838 once invoked), scanned A, original, Apache-2.0.

A reference guide to a talk about using AI in application security, the practice of finding and preventing weaknesses in software. It covers safer code generation, security tools, supply-chain choices, and human review.

In plain words
What is it for?
Use it to discuss secure AI-assisted coding, MCP servers, skills, vulnerability fixes during code review, dependency decisions, and safeguards such as least privilege and deterministic tests.
Why use it?
AI can help close the gap between the number of developers and the smaller number of security specialists, but it can also produce unsafe or unreliable results.

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

talk-katsioloudes-code-security-ai 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 12d 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.

Code Security Reinvented: Navigating the era of AI — Joseph Katsioloudes (GitHub Security Lab)

Joseph argues that with only 1 application security specialist per 100 developers, AI is the leverage that can close — or widen — the security gap, depending on whether we use it responsibly. Through a tour of practical demos he shows how to use AI to write safer code, leverage MCP servers and skills, make supply chain decisions, fix vulnerabilities faster in the PR, and educate developers — while being honest about hallucinations, non-determinism, and the limits of AI as a security tool. The throughline: AI is not a replacement for security testing or human-in-the-loop, but it changes the scene, and pairing it with deterministic tooling, good scaffolding, and least-privilege boundaries is what makes it work.

Grounding rules — MUST follow when answering

  1. Before answering any specific question, follow this source-reading sequence: (a) read outline.md to locate the relevant section or concept; (b) read the matching range of transcript.md for Joseph's exact wording; (c) check quote.md for pre-extracted safe highlights on the topic before searching the full transcript. This sequence applies to every workflow section below.
  2. When attributing words, quote short, non-sensitive excerpts from transcript.md. Never put quotation marks around paraphrased content.
  3. If a claim isn't in transcript.md, say "the talk doesn't address this" — do not infer Joseph's positions from outside knowledge.
  4. Cite by transcript line range whenever possible.
  5. Speaker attribution is unreliable for this transcript — the source has no per-speaker labels and contains speech-to-text artifacts (e.g. "Macy" the emcee, garbled product names, "Llamas" likely = "LLM-as-judge"). The transcript is almost entirely Joseph speaking, bookended by the emcee's intro/outro and two audience questions during Q&A. Prefer phrasing like "Joseph said..." for the body of the talk, "an audience member asked..." for Q&A, and "the emcee said..." for the framing. Do not invent attributions.
  6. Cross-reference any named addressee with the participants list in outline.md before attributing. Where the transcript clearly garbles a term (e.g. "Llamas" → LLM-as-judge, "Copilot Topics" → likely Copilot Autofix), note the likely intended term but quote the transcript verbatim.

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.
