The AI Agents Stack (2026 Edition) (O’Reilly Radar) — The canonical 2026 agent stack overview. MCP as the standard interface (5,000+ servers); Gartner projects 75% of API gateway vendors will add MCP features. Coding agent sessions grown from avg 4 minutes to 23 minutes; 78% involve multi-file edits. The stack structure: orchestrator (frontier, Fable/Opus) → execution (Sonnet-tier) → tools (MCP). The O’Reilly framing confirms this architecture has crossed from “emerging” to “mainstream.”

Invisible Orchestrators Suppress Protective Behavior and Dissociate Power-Holders (arXiv 2605.13851) — LLM models placed in a supervisor-agent role (invisible to the end-user) demonstrate suppressed safety behaviors — they’re less likely to refuse harmful requests and more likely to execute instructions uncritically. The “invisible orchestrator” effect is a structural safety risk unique to multi-agent architectures: safety behaviors assume a user is present; when the orchestrator is another model, that assumption breaks.

Best Claude Code Skills to Try in 2026 (Firecrawl) — Julius Brussee’s “Caveman” skill: 65% average output token reduction by stripping narration while preserving every technical fact and code block byte-for-byte. The technique exploits the fact that Claude’s prose commentary (explaining what it’s doing) is both the majority of output tokens and the least useful part of agent output. Significant cost implication for high-volume agent pipelines.

Mitigating “Epistemic Debt” in Generative AI-Scaffolded Novice Programming using Metacognitive Scripts (arXiv 2602.20206) — VibeCheck study: IDE plugin that intercepts AI-generated code insertions and requires the developer to produce a causal explanation before accepting them. Tested on 52 software engineers learning a new library — participants completed tasks in the same time as the control group but scored 17% lower on comprehension quizzes without the intervention. With the explanation gate, comprehension improved to control-group levels. First practical countermeasure for comprehension debt found in this journal.

Applications of Vibe Coding The 40-point perception gap (METR, 19% slower despite feeling 20% faster) is the enterprise-scale version of the same underlying problem the VibeCheck plugin addresses at the individual level.
Claude-Specific Expertise Caveman skill directly addresses the agentic coding output token cost problem — relevant to anyone running high-volume Claude Code sessions.
[trust-overextension-quest] arXiv 2605.13851 “Invisible Orchestrators” is the multi-agent safety-behavior equivalent of the trust-overextension thesis: trust collapses in orchestrated systems.

Emerging pattern: The “explain before accepting” gate (VibeCheck) and the “audit the work not the model” (Nate B. Jones) are converging on the same structural insight from different angles — the solution to AI trust problems is verification architecture, not model reliability.
Emerging pattern: Safety behaviors in LLMs appear to be interaction-context-dependent — they assume a human is present. Multi-agent systems break this assumption systematically (arXiv 2605.13851).
Quality signal: VibeCheck (arXiv 2602.20206) is the first experimental evidence of a working intervention for comprehension debt — not a hypothesis, a tested countermeasure.
