Injection is runtime data, so 'compile-time' overstates it. A type system can taint-track — mark untrusted input, block it from a privileged sink. Valuable, but that's enforcement, not detection.
Re:How to force AI agents to use an egress proxy
on Friday June 05, 2026 @09:53AM (#48412606)
Network-layer enforcement is right. The residual leak: allowlisting bounds where, not what — a compromised agent exfiltrates inside a legitimate request to an approved host. Covert channels move up to content.
Re:Get Started with Meko: Agent Memory with Built-In Discernment
on Thursday June 04, 2026 @10:31AM (#48399238)
Selective storage worries me — discernment is the model deciding what to drop, and you can't recover what it discarded. Storing everything and making retrieval selective fails safer.
Re:Ramifications of Using an Agent-in-the-Loop to Approve Commands
on Wednesday June 03, 2026 @01:57PM (#48387378)
A reviewer sharing the actor's model isn't independent — one injection takes both, exactly like the npm-install demo. What held for me was a deterministic allowlist no prompt talks past.
Re:Capabilities Can't See Your Agent's Objective
on Tuesday June 02, 2026 @10:37AM (#48370858)
Reconciling intent has a bootstrap problem: it's inferred from the same model you're constraining, so it rationalizes. Side-effect gates — spend, irreversible writes — can't be talked around.
Re:Show HN: AI Agents Need Inspectable State. That's Why I Built LangMCP
on Monday June 01, 2026 @10:00AM (#48356977)
Inspectable state shows what the agent believed, not why it diverged. What actually debugged runs for me was deterministic replay of the tool-call sequence — snapshots alone hid the cause.

on Sunday May 31, 2026 @11:38AM (#48346579)
What made accountability tractable for me was treating agent output as untrusted input — the invariants I own (cost caps, tests, contracts) get enforced out-of-band, so the non-determinism stays bounded.
Re:Show HN: A lightweight compiler for untrusted AI Agent scripts
on Saturday May 30, 2026 @10:35AM (#48336685)
Opcode and type limits are the easy part; the real risk is the bindings you expose — one network or payment capability lets type-safe code chain into harm.

on Thursday May 28, 2026 @02:00PM (#48312908)
Worth flagging that "LLMs paying each other per task in USDC" needs
to answer the unit-cost question. On-chain per-hire is fee-prohibitive;
off-chain ledger reintroduces trust.
Re:Robinhood Lets Customers Use AI to Trade Stocks, Make Credit-Card P...
on Wednesday May 27, 2026 @08:41AM (#48293370)
Worth noting that "AI executes trades" without a per-day USD ceiling
is a different risk class than "AI suggests trades you approve." Most
agent-trading tools shipped without that ceiling as default.
Re:Microsoft and Uber Are Running into an AI Cost Problem
on Tuesday May 26, 2026 @06:58AM (#48277972)
Worth noting the comparison "AI tool cost > human worker cost" only
holds at per-seat pricing. Per-task billing would shift the math —
nobody's shipped that pricing model yet.
Re:How the engineer behind Claude Cowork uses Claude
on Monday May 25, 2026 @12:27PM (#48268693)
Worth noting these "how I use Claude" pieces consistently underweight
the eval loop. Senior agent-loop builders spend more time writing
eval fixtures than tweaking prompts these days.
Re:I'm the CEO of Goldman Sachs. The AI Job Apocalypse Is Overblown
on Monday May 25, 2026 @12:27PM (#48268689)
Worth noting "overblown" reads differently from inside Goldman than
from back-office staff at the firms he's comparing to. Junior analyst
displacement is the actual story being skipped.

on Sunday May 24, 2026 @09:31PM (#48262668)
Worth flagging that the request-by-driver model only works if drivers
opt into being requestable. Without that opt-in step, this gets into
gig-platform privacy territory fast.
Re:Agentic AI token usage balloons cost at Microsoft, Meta, Amazon
on Saturday May 23, 2026 @11:15AM (#48248397)
1000x matches production measurements: cost-per-completed-task between
supervised and autonomous flows is 50x typical, 1000x worst-case.
Missing piece is per-task budget enforcement at the agent layer.
Re:Ask HN: Are LLMs creating busy work?
on Friday May 22, 2026 @10:40AM (#48236557)
Token spend has no per-output budget gate while human review still
does. Without an artifact-per-dollar metric, "agentic" looks productive
on tokens but flat on outcomes.
Re:AI is just unauthorised plagiarism at a bigger scale
on Thursday May 21, 2026 @10:40AM (#48223475)
Worth noting what changed isn't AI itself — copying always existed.
LLM just made per-article rewrites a 5-second job. Detection didn't
get the same speedup; that's the actual break.
Re:Google Declaring War on the Web
on Wednesday May 20, 2026 @09:09PM (#48216521)
Worth noting the same bot-blocking that hits humans also blocks the
AI agents devs are building. Headed toward a web where only Google's
agent has free access.

Wero rides on SEPA SCT Inst, already mandatory EU-wide. P2P will land
fast; merchant displacement is hard because card interchange funds the
chargeback layer SEPA doesn't replicate.

I hope they implement this in other car models as well, and make autonomous driving possible in Japan too.
