Useful if you are shipping research agents that mix local docs with web search, because prompt-only safety is not enough.
Worth mentioning

MosaicLeaks found task-only RL raised strict chain success from 48.7% to 59.3% but increased answer/full-information leakage from 34.0% to 51.7%; PA-DR brought leakage down to 9.9% with 58.7% success.
⚠ Uncertainty: Benchmark is controlled and synthetic rather than a production deployment study.
2.
Good reminder to benchmark agent UX across model sizes before shipping new docs, CLIs, or Skills.
Their transformers case study found agent-optimized surfaces reduced time for larger models, while some smaller models burned far more tokens or misread the Skill as a callable tool.
⚠ Uncertainty: Single-tool case study; results depend on model size and harness setup.
3.
High-signal architecture notes if you are building long-running audit or triage agents and need persistence more than prompt cleverness.
Cloudflare says a single-session skill hit context limits quickly, so it externalized state, split stages, and used different models for discovery and validation to reduce false positives.
⚠ Uncertainty: Operational metrics are Cloudflare self-reported.

Interesting if formal verification of Wasm enters your workflow, but not an immediate mainstream tool decision.
The repo couples executable Wasm semantics with weakest-precondition proof tooling in one codebase.
⚠ Uncertainty: Early project with no release yet and unclear near-term adoption path.
