TLDR
• Evaluations alone don’t improve AI quality. Convert results into fixes with a structured loop: diagnose low‑scoring cases, iterate on prompts and parameters, compare versions across datasets, and track progress over time with versioning and observability.
• Focus on evaluator‑aligned changes (faithfulness, format adherence, helpfulness), dataset‑level comparisons, and auditable prompt versioning to prevent silent regressions and cost/latency drift.
• Strengthen safety and reliability by formalizing output contracts, retrieval policies, and monitoring. For adversarial risks and integrity concerns, review the Maxim AI engineering note on prompt injection and jailbreaks: Maxim AI.
Introduction
Evaluations quantify agent performance, but the value comes from what you do next. Post‑evaluation action plans should move from raw scores to targeted fixes that are measurable, repeatable, and safe. That means diagnosing failure modes at the dataset level, adjusting prompts and parameters with evidence, publishing new versions, and monitoring changes over time. This article outlines a direct, technical workflow grounded in evaluator metrics, version‑linked decision‑making, and safety posture. For product documentation and platform capabilities, see Maxim’s documentation hub: Documentation (https://www.getmaxim.ai/docs).
Diagnose: Turn Low Scores into Specific, Testable Hypotheses
Start by mapping each low metric to its most likely root cause and a concrete fix you can validate at dataset scale.
• Faithfulness (factuality and grounding)
▫ Symptoms: hallucinations, unsupported claims, poor citation behavior.
▫ Actions: tighten retrieval policies; require citations or refusal on low confidence; clarify what sources the agent must rely on; verify consistent context variable wiring.
▫ Why it matters: weak grounding increases risk from prompt injection and adversarial inputs. See security context and failure modes in the engineering note: Maxim AI.
• Format adherence (structured outputs)
▫ Symptoms: invalid JSON, schema drift, inconsistent keys, parse errors.
▫ Actions: specify strict output contracts; add schema descriptions and examples; include stop sequences; reduce optional fields that cause variability; evaluate for format compliance.
• Helpfulness and relevance (task success)
▫ Symptoms: vague answers, missed constraints, unprioritized requirements.
▫ Actions: clarify the instruction hierarchy; add role and task boundaries; include few‑shot exemplars that demonstrate edge handling and tone; remove ambiguous phrasing.
• Latency and cost (performance budgets)
▫ Symptoms: token spikes, slow responses, excessive tool calls.
▫ Actions: lower temperature, set max tokens, tune top‑p or stop sequences; reduce schema verbosity; clarify tool‑use rules to avoid redundant calls; measure token and tool metrics.
• Tool and retrieval misuse (action reliability)
▫ Symptoms: incorrect tool selection, invalid arguments, unnecessary calls.
▫ Actions: refine tool descriptions and constraints; provide do/don’t examples; enforce argument validation; penalize contradictory calls through evaluators; add recovery logic.
Use evaluator summaries and per‑case logs to isolate patterns across scenarios and personas. Assess whether failures are concentrated (e.g., certain inputs or contexts) and prioritize fixes that improve whole clusters rather than single anecdotes.

Iterate: Apply Evaluator‑Aligned Edits and Compare at Dataset Scale
Move beyond ad‑hoc edits by aligning changes to the exact metrics that matter and validating across comparable test suites.
• Make targeted prompt edits
▫ Add explicit roles, constraints, and step sequencing for deterministic behaviors.
▫ Enforce structured output with a minimal, stable schema and explicit validation rules.
▫ Strengthen retrieval instructions (citation requirements, refusal policies, grounding statements).
▫ Introduce few‑shot examples to clarify formats, tone, and edge-case handling.
• Tune parameters methodically
▫ Lower temperature for precision tasks; set max tokens to cap cost; define stop sequences to prevent run‑on outputs.
▫ Stabilize sampling behavior for production consistency; isolate parameter changes to attribute cost and latency effects.
• Compare versions side‑by‑side
▫ Use dataset-level comparisons rather than spot checks; evaluate score deltas for each metric (faithfulness, format, helpfulness) and performance (latency, cost, tokens).
▫ Deep‑dive into per‑entry logs to confirm that changes target the intended failure modes and do not introduce regressions elsewhere.
• Document intent and scope
▫ Record what you changed (messages, schema, parameters), why (linked to evaluators), and what you expect to improve (target thresholds). Keep descriptions concise and technical.
Refer to product guides and reference materials via the docs hub: Documentation. Keep changes traceable so teams can collaborate efficiently and reviewers can verify improvements.
Version: Publish, Diff, and Track Changes Over Time
Versioning turns prompt edits into auditable artifacts tied to evaluation runs.
• Publish versions for every meaningful change
▫ Include descriptions that state assumptions, intended improvements, and evaluator focus. Avoid vague notes; link to datasets and runs used for validation.
• Diff across versions
▫ Compare messages, configuration, and parameter modifications; confirm that changes align with the diagnostics and do not affect unintended behaviors.
• Link runs to versions
▫ Track performance longitudinally to catch regressions early. Use retrospective comparisons (e.g., month‑over‑month) to quantify cumulative impact on quality, latency, and cost.
• Standardize approvals
▫ Establish thresholds for each evaluator that must be met to advance versions to production flags. Keep decisions evidence‑based and shareable with stakeholders.
Version control for prompts and workflows is essential for audits, compliance, and production reliability. For product documentation and capabilities, see Documentation (https://www.getmaxim.ai/docs).
Monitor: Observe in Production and Close the Loop Weekly
Pre‑release evaluations cannot capture every real‑world condition. Monitoring turns live signals into ongoing improvements.
• Sample real sessions and traces
▫ Periodically run evaluators on production traffic; include node-level checks for tool calls, argument validity, and schema adherence. Track user feedback signals where applicable.
• Set alerts and review queues
▫ Configure thresholds for evaluator scores, latency, and cost; route low-score sessions to human review queues for targeted triage.
• Curate datasets from logs
▫ Convert recurring failures and edge cases into new test items; tag by persona, scenario, and outcome. Keep datasets dynamic so evaluations reflect reality.
• Schedule improvement cycles
▫ Every week, publish a new candidate version based on production learnings; re‑evaluate against updated datasets; retire underperforming prompts and roll back if necessary.
These practices ensure continuous quality and stability, especially in complex agentic systems. To understand security and integrity implications, review the prompt‑injection risks and defensive posture discussed in the engineering note: Maxim AI.
Conclusion
Evaluations are the start, not the finish. Effective post‑evaluation plans diagnose low scores precisely, implement evaluator‑aligned fixes, compare across datasets, and version improvements for auditability. Continuous monitoring then closes the loop, converting live signals into weekly upgrades. This disciplined approach raises agent reliability, prevents silent regressions, and keeps costs and latency in check.
