Experiment Hooks

Category: Science & Research  ·  Sub-category: science-misc  ·  Last updated:
Author pre/post-iteration hooks for an experiment session. Use when the user asks to add research fetching, Slack/webhook notifications, persistent learnings, auto-tagging, anti-thrash intervention, idea rotation, or any side effect around iterations.

From the source SKILL.md

Optional scripts that run at iteration boundaries in an experiment session. Two hooks, both transparent to the loop-running agent — their effect is a file on disk or a steer message.

experiment.hooks/
  before.sh    # fires before each iteration (prospective)
  after.sh     # fires after each experiment-log (retrospective)
