What arscontexta runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.

Cursor
Cursor also runs Claude Code hooks from .claude/settings.json, so copy these hooks there to use them in Cursor.
What fires, and when
SessionStart
Fires once when a session begins, and again after a context compaction. It is where a plugin sets up its environment, or restores state the compaction dropped.

Ars Contexta plugin hooks — session orientation, note validation, auto-commit
A second brain for your agent. A Claude Code plugin that generates complete knowledge systems from conversation. You describe how you think and work.
Stars on GitHub
A skill that shapes Claude Code's output for readers with ADHD: it leads with the next action, numbers multi-step work, restates state across turns, drops tangents, gives specific time estimates, and makes progress visible. Invoke it with /i-h.
@ayghriA Claude Code plugin that makes the assistant work harder when it stalls or repeats failures. It adds pressure-style coaching, plus skills for workplace reminders and senior engineer, CTO and team-lead modes for planning and execution.
@tanweaiTurns the sources you read, such as papers, articles and transcripts, into a linked wiki of Markdown notes in Obsidian. Claude keeps sources and citations so every summary can be traced back to its origin.
@agricidanielGives Claude Code a persistent second brain stored as plain markdown in an Obsidian vault. Notes rewrite themselves as new sources arrive, and scheduled agents handle research synthesis and note capture.
@eugeniughelburA Claude Code workflow plugin that learns from your corrections and keeps a self-correcting memory across sessions. It adds skills for agent teams, parallel worktree batch changes, bug capture as GitHub issues, project auto-setup and context compaction.
@rohitg00Helps you learn any topic with a first-principles curriculum, guided tutoring, and spaced review that schedules free-recall practice. Includes coaching for retention stats and study strategy.
@nagisanzeninA command line tool for HEY that lets you read and send email, manage contacts, labels, calendars, todos, habits, time tracking and journal entries from the terminal or from your coding agent.
@basecampLets you manage Basecamp projects, todos, cards, messages, files and schedules from your terminal or from Claude Code, so you stop switching to the web app for routine updates.
