Prompt Injection and Jailbreaks in Depth

A defender's field guide to the injection and jailbreak techniques a red-teamer probes for — the taxonomy, why each one works, and how to turn it into a re-runnable test suite that maps every passed test to a concrete fix.

A deeper, test-focused look at injection and jailbreak families — direct vs indirect (the RAG/agent threat), role-play, obfuscation, many-shot, multi-turn, cross-lingual — plus a red-team methodology: build a probe suite, mutate, test input and retrieval paths, measure, re-test.

Prompt Injection and Jailbreaks

Why the #1 risk on the OWASP LLM Top 10 has no clean fix — the model can't tell your instructions apart from the text it reads — and the defense-in-depth pattern that actually shrinks the blast radius.

The #1 LLM risk: direct vs indirect prompt injection (the latter is the real threat for RAG and agents), jailbreak families, and honestly-rated defense-in-depth — delimiting untrusted data, least-privilege tools, human-in-the-loop, and detection's limits.

Prompt Engineering as Engineering

Treating the prompt as a real engineering artifact — grounded in how a next-token predictor actually works — with roles, specificity, few-shot examples, decomposition, chain-of-thought, grounding, temperature, injection defense, and versioned Go templates you can test.

Prompt engineering as a real engineering discipline: roles, specificity, few-shot, decomposition, chain-of-thought and its cost, grounding, and prompt injection — plus building prompts as versioned, testable Go text/template templates you treat like code.

Policy Is Code, Not a Prompt

Prompt injection can hijack what a model says, but not what it's allowed to do — as long as policy lives in a middleware pipeline the model never sees.

A system prompt saying never delete records is a suggestion the model can be talked out of. A gateway that returns FORBID for the delete tool cannot. Put enforcement where the model can't reach it and prompt injection stops mattering for access control.

The Agent Harness: guardrails as middleware around the model

Lesson 1 of Harness Engineering in Go — why the input guardrail is a hard block, not a warning, and how a plain `net/http` handler wraps the model call so it tests without a running server.

Lesson 1: why the input guardrail is a hard block rather than flag-and-pass, why it counts runes instead of bytes, and how a plain net/http handler wraps the (stubbed) model call so it tests with httptest.

06 · Mixed Workflow — Agents *and* Executors in One Graph

This lesson teaches how deterministic function executors and agent-backed executors compose in one graph with the same `AddEdge` wiring.

One workflow that mixes deterministic executors with two Foundry agent nodes for jailbreak detection and response, joined by the same AddEdge wiring and TurnToken triggering.
