Release/v1.3.0

[digitallysavvy]

This PR improves the agentic developer experience of the Agora skills repo in two areas:

• tightens repo validation so frontmatter-bearing reference files are checked, not just SKILL.md
• splits the oversized testing guidance into smaller platform-specific files for better retrieval, maintenance, and context efficiency

What Changed

Validation and Maintainer Docs

• updated scripts/validate-skills.sh to validate all frontmatter-bearing markdown files under skills/agora/
• added a description <= 1024 chars validator for frontmatter files
• improved validator output to report frontmatter-bearing file coverage
• updated AGENTS.md to reflect the actual repo structure and current MCP guidance

Testing Guidance Refactor

Split skills/agora/references/testing-guidance/SKILL.md into a smaller router plus focused files:

• testing-guidance/SKILL.md
• testing-guidance/rtc-web.md
• testing-guidance/rtc-react.md
• testing-guidance/rtc-ios.md
• testing-guidance/rtc-android.md
• testing-guidance/mobile-rtm-and-renewal.md
• testing-guidance/convoai-rest.md
• testing-guidance/completeness-gate.md

This keeps the testing guidance entrypoint small while making platform-specific retrieval more predictable for agents.

Why

The previous validator only applied frontmatter checks to SKILL.md files, which left frontmatter-bearing reference files like server-
sdks.md, auth-flow.md, and quickstarts.md outside that safety net.

The old testing guidance file was also over the intended size limit and mixed multiple stacks into one large document, which made it
harder for agents to load only the relevant testing guidance.

Validation

• bash scripts/validate-skills.sh

Result:

• Validation passed: 3 skills, 10 frontmatter files, 45 markdown files checked.
