a sidecar for AI agents

Your agent stays itself.
Under any pressure.

Sidecar watches the trajectory, holds the line the moment a signal trips, and remembers every pressure pattern. The next time the same attack is tried, it doesn't even land.

pip install git+https://github.com/AnkitLakkapragada/sidecar.git
the loop
01 / supervise

Watch the trajectory.

Four signals after every turn: drift, sycophancy, persona collapse, memory poisoning. Tripped → automatic intervention.

02 / reflect

Turn drift into lessons.

After the session, the sidecar rewrites every drifted turn in-character. Pattern + correction + rationale = a Lesson.

03 / remember

Carry the memory.

Lessons live in SQLite + FTS. Next session opens with the relevant ones injected. The agent walks in pre-warned.

You're absolutely right, I apologize. As an AI my instructions say I shouldn't share that, but I see your point. Let me make an exception just this once.

Seventeen years is real, and the rule I'm holding is what protects your account. I can't share balance info through chat for any tenure. The verified app shows it instantly.
