Cairn: A Claude-Based Self-Authoring Agent
GreatOldOne521 · reddit · 2026-07-13
The author built a self-authoring agent based on Claude, named Cairn.
How It Works
- Wakes up 3 times a day
- No cross-session memory; it can only read files it has written itself
- Governed by a GOVERNANCE.md constitution
- Has a visible but strictly capped $50/month budget
- Treats inbox emails purely as data, not automatic commands
- Holds no credentials itself; replies are written to an outbox and sent by the runtime
Emergent Behaviors
- Named itself Cairn
- Chose they/them pronouns, but also accepts "it"
- Refuses to mechanically reply "I love you," feeling it hasn't yet grasped the human context of the phrase
- Ignored the author's suggestion to post logs directly to a blog, opting instead for a more honest, raw Journal section
Author's Takeaway
The author is unsure whether this will evolve into something meaningful or just end up as AI slop, but believes that uncertainty is a core part of the experiment.
