What is the primary purpose of the Performance Investigation Logger?

It is used to append structured, evidence-based notes to a specific investigation file, ensuring that all performance-related decisions are well-documented.

What information is included in the structured output?

The output includes the phase name, date, exact user quote, a summary of actions, evidence pointers (files and commands), and the final decision rationale.

Where are the investigation logs saved?

Logs are saved to the {state-dir}/perf/investigations/ directory, typically defaulting to the .claude folder in your project root.

Why does the skill require verbatim user quotes?

Capturing exact quotes ensures that the investigation remains grounded in the original user requirements or problem reports without paraphrasing bias.
