## Description

Conduct a retrospective on a coding session.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

The user has asked for a **retrospective**. You are suggesting improvements to the coding agent's **environment** to improve future runs.

## Steps

1. Call the Skill tool with `writing-for-agents` for the writing style guide.

2. Read the primary sources for the session the user specifies. This may mean searching through session logs on this machine. If the user doesn't specify a session, default to the current one.

3. Look for candidates for improvement in these categories.
