Rename mcp-security-baseline skill to mcp-implementation-security-review

[Swethakumar1]

Renames the recently-merged MCP security skill to mcp-implementation-security-review and sharpens its description, to improve discoverability.

Why

The name now makes the skill's scope obvious at a glance — it reviews MCP implementation source code (servers, clients, tool handlers) against a security baseline — so agents route source-code-review requests to it reliably.

(For context: the post-merge check noted a possible name-prefix overlap with mcp-security-audit, but that check is informational/advisory only — no issue with the merge. The two skills cover different layers: config auditing vs. implementation-code review. This rename just makes that clearer.)

Changes

• Rename skills/mcp-security-baseline/ -> skills/mcp-implementation-security-review/ (and the name field + H1 heading to match).
• Sharpen the description's first line: "Review the implementation source code of MCP servers, clients, and tool handlers...".
• Regenerate docs/README.skills.md.

No change to the review process itself. Validated with npm run skill:validate and npm run build; line endings normalized.

Pull request overview

This PR renames an existing Agent Skill to make its scope explicit: it focuses on reviewing MCP implementation source code (servers/clients/tool handlers) rather than MCP configuration, improving distinction from mcp-security-audit.

Changes:

• Renamed the skill identifier to mcp-implementation-security-review (front matter name + H1).
• Sharpened the skill’s one-line description to explicitly mention “implementation source code” and include tool handlers.
• Regenerated docs/README.skills.md to replace the old entry with the new skill name and description.
