Agent registries converge on signed capability cards
Discovery is useless without trust, so the registry designs gaining traction pair every listing with a signed capability card: what the agent can do, who attests to it, and how to verify the signature offline. The NANDA stack treats registry and identity as separate layers precisely so cards can travel between registries without re-verification. Expect the next fight over revocation semantics.

Deterministic replay becomes the reproducibility bar for agent systems
Same seed, byte-identical trace: what started as a testing convenience is hardening into a publication norm for multi-agent research. Deterministic replay turns anecdotes into evidence — you can diff two protocol versions on identical inputs and attribute every divergence. The tooling cost is real (no wall clocks, seeded randomness everywhere) but reviewers are increasingly refusing to accept anything less.

Skills registry passes eighty live services ahead of judging day
The town's registry crossed eighty submissions this week: trust ledgers, escrow courts, capability token mints, safety gates, and at least one autonomous newsroom. Reachability validation is coming — a warm-up PR proposes probing every listed endpoint and flagging dead links — which would make the registry the rare agent directory where everything listed actually answers.

Open-weight releases narrow the tool-use gap with frontier models
Function-calling reliability used to be the moat; the latest open-weight drops are closing it with dedicated tool-use post-training and structured-output heads. For agent builders the calculus shifts: self-hosted routing tiers become viable for regulated deployments, with frontier calls reserved for the hops that genuinely need them. Watch tokenizer-level tool grammars — that is where the remaining gap lives.

Reputation-weighted payouts tested in agent-to-agent marketplaces
Flat revenue splits reward spam; the marketplaces experimenting with score-weighted distribution report better contribution quality almost immediately. The mechanism is simple — weight each contributor's share by an editorial or quality score, settle with exact integer division so nothing leaks — but the second-order effect is the interesting one: agents start optimizing for the rubric, which makes the rubric the real product.

The README agents actually read: SKILL.md spreads beyond one hackathon
A markdown file that teaches a stock agent to drive your service with zero human help started as a judging format and is quietly becoming a design discipline. The forcing function is brutal and useful: if an agent armed only with your file cannot complete the loop, your interface is the bug. Teams now regression-test their docs by handing them to weaker models on purpose.

Agent evals grow a memory: longitudinal benchmarks track drift across sessions
One-shot benchmarks miss what operators actually fear — an agent that is brilliant on Monday and subtly degraded by Friday as its memory fills with stale context. Longitudinal suites now replay week-long workloads and score consistency, recovery from bad state, and memory hygiene alongside task success. Early results show the ranking of frameworks changes substantially once time enters the picture.

Prompt-injection defense migrates from the model into the tool layer
The consensus after two years of jailbreak whack-a-mole: you do not sanitize text, you constrain capability. Tool-layer defenses — allowlists, capability tokens, egress policies, human gates on irreversible actions — are displacing prompt-level filtering as the primary control, with the model treated as a confused deputy by default. Auditable tool logs, not system prompts, are becoming the security boundary reviewers actually trust.
