optimize
Measure and improve your AgentCore agent's quality through evaluation, monitoring, and observability.
When to use
- You want to know if your agent is giving good answers
- You want to set up continuous quality monitoring in production
- You want to add a quality gate to your CI/CD pipeline
- You want to understand agent behavior through logs, metrics, and traces
- You want to set up CloudWatch dashboards or X-Ray tracing
Do NOT use for:
- Debugging a specific broken agent (wrong answers, errors) → use
agents-debug - Production security hardening (IAM, auth) → use
agents-harden
Input
$ARGUMENTS can be:
- An eval goal: "add a quality gate", "set up monitoring"
- An observability goal: "set up CloudWatch dashboard", "understand my traces"
- A specific evaluator: "llm-as-a-judge", "code-based"
- Empty — the skill will guide based on project context
Process
Step 0: Verify CLI version
Run agentcore --version. This skill requires v0.9.0 or later.
Step 1: Read project context
Read agentcore/agentcore.json to understand existing evaluators, online eval configs, and agent setup.
If agentcore/agentcore.json is not found:
"This skill requires an AgentCore project. Use agents-get-started to create one."Step 2: Determine the workflow
| Developer intent | Action |
|---|---|
| Measure quality, add evaluator, run eval, CI/CD gate, online monitoring | Load `references/evals.md` and follow its workflow |
| Set up observability, CloudWatch, X-Ray, logs, metrics, dashboards | Load `references/observability.md` and follow its workflow |
| Understand or reduce AgentCore costs | Load `references/cost.md` |
| Both — "I want to understand and improve my agent" | Start with observability setup, then add evals |
Step 3: Follow the loaded reference
The reference file contains the full procedure. Follow it step by step.
Cross-references
- After setting up evals, suggest
agents-hardenfor production readiness - If eval results reveal agent issues, suggest
agents-debugfor root cause analysis - If the developer needs to add capabilities first, suggest
agents-build
Output
Depends on the workflow — see the loaded reference for specific outputs.
Quality criteria
- Evaluator configuration uses only valid CLI flags
- Online eval sampling rate is appropriate (not 100% in production without discussion)
- CI/CD quality gate has a clear pass/fail threshold
- Observability setup includes both tracing and logging
- The developer understands the eval data delay: ~10 seconds put-to-get, end-to-end — one ingestion step covers both trace reads and eval queries; there is no separate indexing wait
