Name the complete default
Record the model, harness, instructions, tools, permissions, routing, workflow, checks, and runtime as one Stack Release that teams can identify six months later when a regression returns.
For Platform & DevEx
What should Platform teams standardize for coding agents?
Platform teams already version CI policy, toolchains, and developer environments, while coding-agent models, harnesses, instructions, tools, permissions, and workflows now change just as often. Treat them that way.
What the release gate checks
The evidence behind the decision
Each result stays tied to the Stack Release, workload, repository state, and coverage that produced it. If evidence is missing, the gap remains visible in the release call.
Test before adoption
Compare the current and candidate defaults on tasks from the teams and repositories they will affect, with the same starting state and acceptance policy.
Keep more than one good default
Routine maintenance and database migrations may need different releases, so a platform standard can include several qualified paths with explicit workload boundaries instead of forcing one blanket choice across every repository and team.
Feed failures back into the platform
Reviewer corrections, CI recoveries, reverts, and incidents become candidate regression cases that the next shared default has to face before another team inherits it.
Bring us the next stack change
Fullbeam recommends which workloads should move, while GitOps, MDM, or your internal platform stays in charge of deploying the approved configuration.
