This July 15 paper treats context quality as an independent leading indicator of agent reliability, scoring it with multi-juror consensus across role clarity, guardrail coverage, instruction consistency, tool schema quality, grounding sufficiency, injection hardening, and token efficiency (arXiv 2607.14275). The mappings are specific enough to act on: grounding sufficiency predicts hallucination resistance, guardrail coverage predicts manipulation resistance, instruction consistency predicts instruction-following, tool-schema quality predicts tool-use effectiveness. Run it as a deploy-time preflight, separate from behavioral evals, for a non-circular signal on which failure mode you're about to ship. Harness is open source.

arXiv 2607.26598 targets the failure where an agent recovers from an error within an episode but hits the identical failure in later tasks, because post-episode feedback never revises the persistent harness. Guided by a domain-level Evolution-SOP, it writes episodic memory rec...
It treats the executable runtime, context construction, tool mediation, action validation, execution recovery, as the thing to learn. A separate harness engineer converts batches of target-agent failures into validated executable patches, with same-batch reruns of the frozen t...
Skill-α (arXiv 2608.01678) reframes skill generation as RL over sequential edits, decomposing skill construction into individually evaluable changes. The novel signal is a rollback reward that scores each modification by comparing downstream task execution using the original s...
This one annoyed me, because I've been running the losing pattern. SWE-QA (arXiv 2608.01507) compares the sub-agent grep pattern that Claude Code, Codex and Antigravity all ship by default against a pre-built semantic index over the same repository. Semantic search answered 65...
The Claude Code source leak was the biggest story in developer tools this week. But the most important analysis didn't come from the people picking through feature flags and Easter eggs. It came from Sebastian Raschka, who read the 512,000 lines of leaked TypeScript and reache...
Cisco's State of AI Security 2026 report is the first major infrastructure vendor to formally categorize MCP as an enterprise attack surface. Key findings: 83% of organizations plan to deploy agentic AI, but only 29% feel prepared to secure it. Concrete attack examples: WhatsA...
