Use cases

What you can do with Mutagent

Six use cases across the agent lifecycle, from spec to ship. Pick one to see what it does, what it needs, and what you get back.

Spec

Turn an idea into a signed spec

Define the agent, its architecture, and its eval criteria before any code is written.

  • A signed agentspec.yaml: a framework-agnostic contract with system prompt, LLM config, tools, I/O boundaries, and human-in-the-loop gates
  • A design sidecar carrying the problem, goal, scope, business KPI, failure modes, and the eval rubric
  • A recommended architecture with the agent type locked in

Build( 1 )

Ship a running agent from the spec

Scaffold the code, map your prompts and traces, and wire telemetry into your stack.

  • A working, traced agent as real code on your framework, tests green
  • A functional and regression test suite covering the spec's schema and semantics
  • A faithfulness review report enumerating every spec capability with its trace evidence

Evaluate( 2 )

Score every change with a calibrated judge

Build evals and a judge that matches your team's definition of quality, so every change is measured.

  • A calibrated judge pinned to your quality labels, reproducible run to run
  • A severity-gated scorecard with a fail, incomplete, or pass verdict per behavior
  • Per-behavior criteria and deterministic code checks mined from your failure traces

Diagnose( 3 )

Diagnose why your agents fail

Find the root cause behind runaway cost, silent breakage, and dropped eval scores, then propose the fix.

  • Ranked failure-mode taxonomy
  • Root cause per cluster with cited evidence
  • A review form of issues and recommended fixes

Optimize( 4 )

Optimize agents on a closed loop

Run the diagnose, mutate, evaluate loop and ship fixes that beat baseline.

  • Applied change: prompt, tool, code, or config
  • Pre-merge validation via the evaluator framework
  • Auto-application to your platform, audit trail with rollback

Ship( 5 )
Coming soon

Ship every release behind your evals

Gate releases on your eval suite, pin every version, and roll back when a change regresses.

  • A pass or block verdict on every release
  • A versioned release history
  • A roll back target for every deploy
