    HOW TO EM=
    POWER YOUR AI AGENT TO ACT...WITHOUT AN ACCESS TOKEN
    (SPONSOR) [4]=20

    =
    An AI agent doesn't simply run your code. It runs your code, plus
    whatev=
    er it finds in a =E2=80=9Crelevant=E2=80=9D GitHub issue, support ticket, o=
    r
    scraped web page.

    What happens when you hand your agent an access =
    token and someone
    opens a GitHub issue asking it to leak your credentials=
    ?

    Relay [5] keeps the credential at WorkOS. Your agent names the user,=

    WorkOS attaches that token, refreshes it, and releases it only to
    allo=
    wlisted hosts.

    =F0=9F=A4=94 It's essentially the same credential proxy=
    ing system [6] that's
    been in use in payments for years: you can't leak s=
    omething you never
    held in the first place.=C2=A0=C2=A0

    available through restricted-access =
    programs for vetted cybersecurity
    and life-sciences organizations. Anthro=

    designed to let organizations retain monitoring data =

    Internal testers are said to prefer the model over Anthropic's Opus
    =
    model for coding tasks. The Flash model series is designed to be
    smaller,=
    cheaper, and faster to run, but has lower capability than the
    largest mo=

    WHAT IS AGENTIC TESTING? (14 MINUTE READ) [12]=20
    =

    Agentic testing is where the developer states the goal and the agent
    =
    works out the steps. Agentic tests set a destination, and the agent
    finds=
    its way there. The loop involves the agent looking, acting, then
    looking=
    again. Meta ran this loop at scale and found that only a
    quarter of the =
    output was worth keeping. However, the loop works
    anyway because the code=
    that doesn't pass is automatically discarded.=20

    A TYPE SYSTEM IS A SE=
    ARCH ORACLE (13 MINUTE READ) [13]=20

    Models tend to output better Rust =
    than C++, and better Lean than
    either. Programs in Rust compile after bei=
    ng checked for a specific
    and useful set of properties that the checker c=
    annot be talked out of
    without writing a lexically visible, greppable adm=
    ission. C++ compiles
    carry far less information than in Rust, which means=
    more code will
    compile even if there are errors. Lean allows for brute f=
    orce due to
    its cheap verifier, which is why models are unreasonably good=
    given
    how little code they have been trained on.=20

    end AI systems are not safe
    enough. The company's statements, aimed at Te=

    launch its Cybercab soon at an event on September 3,=
    kicked off a
    social media fight over the weekend. The debate between whi=

    Agentic testing is where the developer = states the goal and the agent works out the steps. Agentic tests set a dest= ination, and the agent finds its way there. The loop involves the agent loo= king, acting, then looking again. Meta ran this loop at scale and found tha=
    t only a quarter of the output was worth keeping. However, the loop works a= nyway because the code that doesn't pass is automatically discarded.
