Agent and tool routing
- which agent does what
- which tools are exposed
- where policy is enforced instead of implied
architecture / systems design
Enterprise agent architecture.
Boundaries before scale.
Large agent systems fail in predictable ways: too many moving parts, vague tool permissions, weak ownership, and rollout rules that do not exist. I fix the structure before those failures become routine.
- → Tool routing
- → Permission boundaries
- → Fallback design
- → Rollout strategy
What I design
Failure and escalation design
- retries and human handoff
- auditability and stop conditions
- fallbacks for when the model should not improvise
Observability and incident readiness
- traces that explain behavior
- diagnostics that point to the failure
- runbooks that shorten incidents
Phased rollout strategy
- controlled release steps
- eval-backed expansion
- less confidence theater
What breaks first
- every team gets its own routing logic
- tool permissions exist only in people's heads
- fallback paths appear after incidents
- rollout policy is just optimism with a calendar
Defaults beat options. Boundaries beat hope.
