Planning with Files
A plan on disk that survives when the agent forgets.
New to this? What open source means and how to read this page.
What it is
A skill that keeps a task plan, findings and progress as markdown files on disk, so a long task can recover after the context is cleared or compacted. Lifecycle hooks feed the plan back to the agent each turn.
Good for
Long tasks where your agent loses track halfway.
The catch
It uses hooks that run automatically every turn, so read what they do before you switch them on. The results claimed in the README are the author's own tests.
