How to Evaluate an AI Content Agent Before It Can Publish
A safe evaluation architecture for content agents: source-backed drafts, deterministic gates, human approval, and measured outcomes.
Separate the agent from the write path
A content agent can research, rank opportunities, draft changes, and explain its evidence without receiving permission to publish. Keep the actual CMS mutation in tested server code that runs only after an explicit approval or a narrowly defined deterministic rule.
This limits the worst outcome of a poor agent run to a poor suggestion. It also creates a stable boundary: judgment can evolve in prompts or Skills, while permissions, validation, concurrency, and audit behavior remain code.
Evaluate the proposal before evaluating the prose
A polished article can still be the wrong article. First test whether the proposal maps to a real audience question, an uncovered content area, and a supported product capability. Reject topics that duplicate an existing canonical page or require claims the available sources cannot establish.
Use deterministic gates for objective failures
- required title, description, author, and publication fields;
- valid internal links and known replacements for dead links;
- source URLs for code snippets and factual product claims;
- no credentials, customer data, or unsupported outcome claims;
- no duplicate target topic owned by another canonical page.
These are contracts, not matters of taste. The server should revalidate them even if the agent claims they passed.
Reserve judges and humans for subjective quality
Use a reviewed rubric for clarity, usefulness, audience fit, and voice. Calibrate model judges against human labels before making them release blockers. When reviewers disagree, preserve the disagreement instead of forcing a confident score.
Make approval safe under concurrency
An approval should bind to the exact draft and source revision the person reviewed. Lock the suggestion after one decision, reject stale approvals, and refuse to overwrite a newer human draft. Record who approved what and which validations ran.
Measure outcomes without confusing correlation for causation
Take a before snapshot when the approved change goes live, then compare later readings with the site-wide trend over the same period. For a new page with no prior baseline, measure a growth curve. Search position, click-through, referrals, and citations answer different questions and should remain separate signals.
Turn escaped failures into permanent coverage
When an approved draft contains a stale claim, broken snippet, duplicate topic, or unsafe link, preserve the evidence and add a regression case. The system improves because failures become reusable tests, not because the agent receives broader permissions.
Where EvalGate fits
EvalGate can capture the agent trajectory, evaluate deterministic and subjective checks, preserve source and approval evidence, compare candidate behavior with a reviewed baseline, and gate the server-side publish workflow. Start with the agent authoring guide and runtime controls.
