feat: Add EDS content operations skills (first third-party contribution)

[focusgts]

Summary

This adds a new EDS Content Operations plugin with 5 skills for content teams operating AEM Edge Delivery Services sites. Contributed by FocusGTS, an Adobe partner.

These skills complement the existing EDS development skills (create-site, building-blocks, content-modeling, etc.) with operational tooling. Zero overlap — all existing EDS skills are developer-focused; these are content-ops-focused.

Skills included

Skill	What it does
content-audit	Audit an EDS page against 40+ checks across SEO, accessibility, performance, and EDS best practices. Produces a prioritized fix list.
geo-rewrite	Optimize content for AI search discoverability (GEO). Scores AI readability on 6 dimensions and generates optimized rewrites.
accessibility-fix	Scan for WCAG 2.1 AA violations and generate fixes at the source document level (Google Docs / Word / da.live).
bulk-metadata	Audit metadata across multiple pages via the query index. Finds gaps and generates a corrected bulk metadata spreadsheet.
content-diff	Compare preview vs live (or any two URLs) to see what changed before publishing. Flags SEO, performance, and accessibility risks.

Why these belong here

• Fills a gap: Adobe's existing EDS skills help developers build sites. These help content teams operate them — auditing, optimizing, checking accessibility, managing metadata, reviewing changes before publish.
• EDS-native: Built specifically for EDS architecture patterns (E-L-D loading, block-based content, metadata tables, .plain.html, Sidekick workflows, document-based authoring). Not generic web tools.
• Tested against live EDS sites: All 5 skills tested end-to-end against main--aem-boilerplate--adobe.aem.live. Test results: focusgts/eds-content-ops-skills/tests
• Follows the spec: agentskills.io format, matching frontmatter fields, directory structure, package.json, .releaserc.json, CHANGELOG.md, and references/ convention.

Changes

• Added plugins/aem/edge-delivery-services-content-ops/ with 5 skills, plugin.json, and reference files
• Added plugin entry in .claude-plugin/marketplace.json

Hi team — just a note on the CI status: the Tessl Skill Lint actually passed (2/2 skills passed, 0 failures). The job exits with code 1 because the comment-posting step gets an HTTP 403 ("Resource not accessible by integration") when trying to create a sticky comment on this fork PR. The 8 warnings in the lint summary are on existing skills (stardust, edge-delivery-services), not the ones in this PR.

The codeowners-coverage check also fails for the same fork-permissions reason.

All other checks pass: Adobe CLA, conventional-commits, license-field, tessl-eval, tessl-review, and validate.

Happy to make any changes if needed — just let us know!

We cannot publish this with references to non-Adobe controlled repos. This is a hard requirement. Also, please check if the skill files follow best practices, as the "You are a..." type prompts seem outdated.

[trieloff]

We will not add skills from non-Adobe controlled repositories to the Adobe Plugin marketplace, as this puts an unmaintainable review burden on us.

This reads like a 2024-style prompt, not like a skill

[trieloff]

@shsteimer @asthabh23 we'll need a code owner for this if we want to take this on.

Thanks for the review, @trieloff. Both issues are fixed in the latest push:

1. Removed all external repo references. Marketplace.json entry no longer includes homepage/repository pointing outside adobe/skills. Plugin.json repository now points to adobe/skills.

2. Updated skill format. Replaced all "You are a..." persona-style intros with direct functional descriptions (e.g., "Audit metadata across an entire AEM Edge Delivery Services site..."). Aligned with the pattern in the existing EDS skills like block-inventory and code-review.

Happy to adjust further if the format still needs work. We have additional content operations skills ready when these are in good shape. Happy to contribute more once a code owner is in place.
