6.7.3 Structured Tracing¶
Why This Sub-Part Matters¶
Structured Tracing is the working skill inside Agent Evaluation and Observability that helps you build the stage artifact, A tool-using agent with typed tools, memory, traces, task evals, prompt-injection tests, and an architecture README, while collecting enough evidence to trust the result. A sub-part is now a folder so longer topics can grow without forcing everything into one huge page.
Study Pages¶
| Page | Purpose |
|---|---|
| Deep Dive | Full explanation, mechanisms, examples, and failure modes. |
| Examples and Practice | Worked exercises, project drills, and self-check prompts. |
Core Ideas¶
- Define Structured Tracing in plain language before naming tools or frameworks.
- Connect it to the stage artifact: A tool-using agent with typed tools, memory, traces, task evals, prompt-injection tests, and an architecture README.
- Measure it with: success, trace completeness, tool errors, cost, and latency
- Name at least one failure mode, because real AI engineering is mostly controlled failure reduction.
- Keep the first implementation small enough to inspect by hand before scaling it.
How to Study It¶
- Read this overview and write the concept in your own words.
- Read the deep dive and identify the input, transformation, output, and failure mode.
- Complete the examples and practice page.
- Add one measurement using: Track success, trace completeness, tool errors, cost, and latency.
Completion Standard¶
- I can explain Structured Tracing without naming a tool first.
- I can connect it to the stage artifact.
- I can show a small artifact, measurement, or test.
- I know how it fails and what I would inspect first.
