Replace 'label' terminology with 'name' per PM feedback

The term 'label' has a specific DNS meaning (string between dots).
Using 'name' is clearer and avoids confusion.

+name: doc-update-past-month
+description: Generate a summary of meaningful public documentation updates from the previous calendar month, scoped to a product area.
+---
+
+Use this skill when asked to summarize recent documentation updates, changelog entries, or "what's new" in the public docs for a specific product area.
+
+## How it works
+
+A helper script at `.agents/skills/doc-update-past-month/bin/doc-update-past-month.js` produces a formatted summary of what changed in the previous calendar month.
+
+**Changelog entries** are discovered by scanning all `.mdx` files under `src/content/changelog/` on `origin/production` and filtering by the `date:` field in frontmatter. This ensures entries are included based on their published date, not when the PR was merged.
+
+**Documentation updates** are discovered by querying git commit dates in the target range and filtering out trivial changes.
+
+## Supported areas
+
+| Argument | Area |
+|----------|------|
+| `app_perf` | Application Performance |
+| `app_sec` | Application Security |
+| `cf1` | Cloudflare One |
+| `platform` | Platform |
+| `dev_plat` | Developer Platform |
+
+The following products are **always included** regardless of area:
+- Support
+- Fundamentals
+- Terraform
+
+## Usage
+
+Run the helper script with the desired area:
+
+```bash
+node .agents/skills/doc-update-past-month/bin/doc-update-past-month.js <area>
+```
+
+## Output format
+
+The script prints:
+
+1. A heading with the previous month and year.
+2. **Changelog entries** in the form:
+   ```
+   New changelog entry for <product>: <title from changelog frontmatter>
+
+   <first sentence from changelog body>
+      - https://developers.cloudflare.com/changelog/post/<date-slug>/
+   ```
+   The title is read from the changelog file's frontmatter (`title:` field), and the summary is the first sentence of the body content (after skipping any leading markdown headings or import statements).
+3. **Documentation updates** in the form:
+   ```
+   Update to the <product> documentation: <commit title>
+      - https://developers.cloudflare.com/<product>/<path>/
+   ```
+
+## Filtering heuristics
+
+The script automatically excludes doc update commits that appear trivial:
+- Typo fixes
+- Broken-link fixes
+- Bulk standardization or formatting changes
+- Commits whose message is only "Update index.mdx" or "Update {file}.mdx"
+- Chore commits (`[Chore]`, `chore:`)
+- Release-notes routine updates
+- Build-warning fixes
+- Trailing-space removals
+- Beta-badge removals
+- Style-guide bulk changes
+
+If a commit touches files across more than five different products, it is treated as a bulk change and excluded.
+
+Changelog entries are not filtered by heuristics — every entry whose frontmatter date falls within the target month is included.
+
+## Manual review
+
+After the script runs, review the output. If you notice any remaining trivial items in the docs section, you may remove them before sharing.
