First practical scenario

AI review is a system, not a script

Read-only code review appears to be a small, safe first step. Yet even the first pilot requires the team not merely to run a model, but to design, measure, and evolve an entire agentic pipeline.

As soon as the team decides to “add AI review,” it inevitably begins discussing not one integration but the structure of a production process:

AgentWhich model or composition of agents finds real defects most effectively?
HarnessWhich harness, system prompt, and set of skills should be used for review?
ContextShould it receive only the diff, the whole module, issue history, or architectural conventions—and how much of each?
AccessDoes the agent need tests, builds, Git history, and project tools, and what must remain read-only?
Jira round tripHow does a finding reach the issue, how can someone ask a follow-up, and how does the dialogue continue with the same executor?
MeasurementWhich findings are useful, where are the noise and misses, how much does a run cost, and which version is actually better?
Local shortcut

Python → Codex → Jira comment

This script demonstrates the idea quickly, but immediately hard-codes one model, one harness, one prompt, one amount of context, and one response path. Every experiment becomes a change to integration code; versions cannot be compared and the choice cannot be justified. It is legacy from the first minute of its existence.

Shared system

Issue → Reviewer.Agent → execution → artifacts → Jira

In Multica, the agent, harness, skills, access, context policy, and return path become configuration and system entities. Every attempt retains a version, trace, and metrics: alternatives can be compared, and the conversation with the executor can continue within the task context.

Multica is not excessive for a single AI review use case. It supports this scenario without a separate custom integration product and simultaneously creates a foundation for subsequent agents, skills, and experiments. The team gets not an authoritarian “this is how we do it,” but a way to demonstrate why a particular pipeline works better than the alternatives.
