Update evals docs: Add tool-usage argument matching feature

[claude]

Summary

• Documents the new argument conditions capability for the Tool Usage check type in evals
• Adds a new "Argument conditions" subsection inside the Tool Usage accordion, covering four match types: exact match, contains, regex, and not empty
• Notes that conditions compose with existing count and position checks, and that a plain-English preview is shown in the form
• Includes a callout that the feature is currently behind the evals-toolusage-argument-matcher feature flag and works for both single-agent and workforce (node-scoped) evals

Scores

	Dimension	Score	What's holding it back
🟡	Consistency	8/10	"workforce" not capitalized (product noun); bold label inside <Info> callout violates CLAUDE.md rule
🟢	Technical clarity	9/10	Feature flag mentioned on line 108 with no guidance on how to enable it
🟢	Non-technical clarity	9/10	No issues found beyond minor accordion content style
🟡	Structure	7/10	No closing CTA; sequential numbered lists should use <Steps>; example scenario accordions use label-value format instead of flowing sentences

Score key: 🟢 9–10, 🟡 6–8, 🔴 1–5.

✨ Overall vibe: This is a comprehensive, well-structured reference for a complex feature — the table-heavy field descriptions, inline demo videos, and example scenarios are all genuinely useful. Three small issues (a callout rule violation, one missing capitalization, and accordion content style) are easy fixes before merging.

🔧 Issues (3)

• build/agents/build-your-agent/evals.mdx:8 — <Info> callout starts with a bold label **Rollout Status**:. CLAUDE.md prohibits bold labels inside callouts — callouts must be a single plain paragraph. Remove the bold prefix and rewrite as prose: "Evals is rolling out progressively, starting with Enterprise customers. If you don't see this feature in your account yet, reach out to your account manager to discuss access."
• build/agents/build-your-agent/evals.mdx:108 — "workforce (node-scoped) evals" — workforce should be Workforce. This refers to the Relevance AI Workforce product feature, which is a proper noun per CLAUDE.md.
• build/agents/build-your-agent/evals.mdx:108 — The sentence "This feature is currently behind the evals-toolusage-argument-matcher feature flag" gives technical readers no indication of how to enable it. Add a brief note: e.g., "Contact your account manager to have this flag enabled." or link to wherever feature flags are managed.

🧩 Component suggestions (2)

• build/agents/build-your-agent/evals.mdx:118–123, 139–168, 233–235, 283–289 — Four sequential procedures use plain numbered markdown lists ("Follow these steps…", "To create a Check from the Checks tab:"). CLAUDE.md says to use <Steps> for sequential procedures to add visual progress indicators. Note: the sibling page prompt.mdx also uses numbered lists, so this may be a repo-wide convention to align rather than a single-file fix.

• build/agents/build-your-agent/evals.mdx:189–221 — The three example scenario <Accordion> components contain bold key-value labels (**Scenario name**:, **Description**:, **Up to**:, **Check**:, *Evaluation Prompt*:). CLAUDE.md says accordion content should be flowing sentences, not label-value formats. Options: rewrite as narrative prose describing each example ("This scenario simulates a frustrated customer who was double-charged…"), or pull the fields into a compact table that mirrors the scenario creation form.

🏗️ Page structure (1)

• build/agents/build-your-agent/evals.mdx — No closing CTA. This is a concept + how-to page that introduces an entire feature; readers finishing it have no suggested next step. Consider adding a ## What's next? section. Natural candidates from the repo: /build/agents/build-your-agent/agent-settings (for publishing configuration that intersects with the Publish section), /build/agents/build-your-agent/triggers (for understanding what fires Agent tasks that Monitor evaluates), or a Workforce overview page if one exists (since the page references workforce evals).
