create_lesson

create lesson

Create a lesson — a proactive rule that fires BEFORE risky operations. Unlike observations (passive), lessons are instructions injected at session start and triggered by PreToolUse hooks. Use after learning from a mistake.

Parameters

Param	Type	Required	Description
rule	string	Yes	The instruction/rule (e.g. 'ALWAYS diff dev vs prod config before deploying')
title	string	No	Short title for the lesson
severity	string	No	How important (default: warning)
project	string	Yes	Project path (full cwd) — ALWAYS pass the current project path. Omit ONLY for truly global lessons.
trigger_tool	string	No	Tool to match: Bash, Edit, Write, NotebookEdit (omit for any)
trigger_pattern	string	No	Regex to match against tool input (e.g. 'amplify.*update-app')

Execution

When invoked with /create_lesson, call the create_lesson MCP tool (server: agent-memory) with rule="$ARGUMENTS". IMPORTANT: Always include the project parameter set to the current project path (full cwd from the session-start context).

create_lesson(rule="$ARGUMENTS", project="<current_project>")
