    Puddle

    Status: Experiment
    Checked 9 October 2026

    Does a parent need another feed, or one small next step?

    Audience
    Parents
    My role
    Solo builder.
    Decision
    A playbook of options the parent chooses. Not an open chat that answers for them.
    Evidence
    I checked the public page at askpuddle.com on 9 October 2026.
    Limits
    I did not test onboarding. I have no evidence yet that the guidance helps a family. Puddle makes no medical, developmental, or compliance claims.
    Open question
    Which suggestions do parents try or change?

    SPEAR

    Status: Experiment
    Checked 9 October 2026

    How can an AI application's security behavior be inspected, not just asserted?

    Audience
    Engineers building LLM applications
    My role
    Builder of the open-source middleware.
    Decision
    Put checks at the runtime boundary and publish an evaluation harness. Do not treat provider safety filters as the whole boundary.
    Evidence
    The public repository shows the source tree, README, and evaluation method.
    Limits
    Source access is not a released package or hosted service. The checks cover input screening and deterministic agent controls. They do not cover live-model output leakage or production latency.
    Open question
    How does it hold up with live models, new attacks, and real integrations? The evaluation is limited. It does not guarantee full protection.
