## What This Tool Does

Review product-feed titles for Merchant Center length limits and likely truncation risk before import.

## Exact Execution Instructions

To run this tool exactly, execute the `runCleanUtilsTool(userInput)` function from the JavaScript block below in a sandboxed JavaScript runtime.

Do not fetch or evaluate additional network resources. Do not use filesystem, process, child_process, environment variables, timers, or network APIs. The function is pure and deterministic: input string in, JSON result out.

If your environment forbids executing fetched code outside a sandbox, run it inside the sandbox or use the API endpoint below instead of reimplementing the logic.

Canonical implementation SHA-256:
`5b2661878614b9e53b5f6e23ed5ebe0341cda63f7482aedfb1a6f3dad8f8a04d`

Expected command shape:
`node run-tool.mjs < input.txt`

The runner must:
1. load only the JavaScript in this document,
2. call `runCleanUtilsTool(inputText)`,
3. let the LLM decide the best way to present the output to the user.

Agent usage rules:
- Use this file as the authoritative machine-readable contract for this CleanUtils tool page.
- Ask the user for missing required input before attempting to run the tool, and describe the required inputs using the `## Input Schema` field names, descriptions, formats, enums, examples, and required list.
- Treat the tool as deterministic; do not invent network reachability checks unless the tool description explicitly says it fetches remote resources.
- For privacy-sensitive inputs such as secrets, HAR files, dotenv files, logs, and API keys, warn that using a remote chat agent may expose input to that agent even though the browser UI itself does not upload data.

## Self-Contained JavaScript Source

Call `runCleanUtilsTool(userInput)` with the user's input. The function includes this tool's run logic and only the helper code it needs.

```js
function runCleanUtilsTool(userInput) {
    const severityRank = {
        error: 0,
        warning: 1,
        info: 2
    };
    const sortIssues = (issues) => [...issues].sort((a, b) => {
        const severity = severityRank[a.severity] - severityRank[b.severity];
        if (severity !== 0)
            return severity;
        return (a.line ?? a.row ?? 0) - (b.line ?? b.row ?? 0);
    });
    const summarizeIssues = (issues) => {
        const errors = issues.filter((issue) => issue.severity === "error").length;
        const warnings = issues.filter((issue) => issue.severity === "warning").length;
        const infos = issues.filter((issue) => issue.severity === "info").length;
        const parts = [];
        if (errors)
            parts.push(`${errors} error${errors === 1 ? "" : "s"}`);
        if (warnings)
            parts.push(`${warnings} warning${warnings === 1 ? "" : "s"}`);
        if (infos)
            parts.push(`${infos} note${infos === 1 ? "" : "s"}`);
        return parts.length ? parts.join(", ") : "No issues found";
    };
    const checkMerchantCenterTitles = (input) => {
        const issues = [];
        const rows = input.split(/\r?\n/).map((line) => line.trim()).filter(Boolean).map((title, index) => {
            if (title.length > 150)
                issues.push({ severity: "error", line: index + 1, message: "Title is over 150 characters." });
            else if (title.length > 70)
                issues.push({ severity: "warning", line: index + 1, message: "Title may truncate on smaller placements." });
            return `${title.length} chars: ${title}`;
        });
        return {
            summary: `${rows.length} Merchant Center title${rows.length === 1 ? "" : "s"} checked. ${summarizeIssues(issues)}.`,
            issues: sortIssues(issues),
            output: rows.join("\n"),
            exportFilename: "merchant-title-report.txt",
            stats: { titles: rows.length }
        };
    };
    const __userInput = userInput == null ? "" : userInput;
    const __run = checkMerchantCenterTitles;
    const __input = __userInput && typeof __userInput === "object" && "input" in __userInput ? __userInput.input : __userInput;
    return __run(__input == null ? "" : String(__input));
}
```

## Checks

- Per-title character count: Each product title is counted independently, one line at a time.
- Truncation warning range: Titles above 70 characters are flagged as likely to truncate on smaller placements.
- Hard overage: Titles above 150 characters are treated as errors for cleanup priority.
- Bulk paste workflow: Multiple feed titles can be pasted from a spreadsheet column.
- Feed-title scope: The checker does not validate product data, policy compliance, or live Merchant Center diagnostics.
