The details
HTTP Terminator turns expert security judgment into an autonomous research pipeline - 10/10
Takeaway: Autonomy became useful only after PortSwigger paired hypothesis generation with deterministic validation, authorized targets, anomaly filters, and expert review.
What changed: PortSwigger released a 25-page whitepaper and AGPL pipeline that generated 30,000 HTTP-desync vectors and validated them against authorized live targets.

Prime Agent makes context and harness state programmable - 9/10
Takeaway: Treat context and harness state as programmable infrastructure; Prime Agent’s gains show the wrapper can matter as much as weights.
What changed: Prime Intellect released an MIT-licensed agent with persistent IPython, programmatic subagents, durable harness state, and reviewable self-refinement.

Skill-Use finds that agents trigger skills better than they follow them - 9/10
Takeaway: Skills are not instructions agents reliably obey: benchmark triggering, step compliance, and forbidden actions separately before trusting reuse.
What changed: Skill-Use evaluates 79 real skills and 177 executable tasks; the strongest model-harness pair reaches only 0.613 overall.
