fix(atomic-agents): use git-subdir source so the plugin subpath resolves

[KennyVaneetvelde]

Problem

The atomic-agents entry in this marketplace is the only subdirectory plugin using source: "url" with a path field. On install, Claude Code clones the full BrainBlend-AI/atomic-agents repo into the cache but does not descend into the claude-plugin/atomic-agents/ subdirectory, so it fails to find .claude-plugin/plugin.json and the plugin loads empty — shown as Enabled in /plugin but with zero agents or skills registered. Users see the plugin in the listing, but /agents does not surface atomic-explorer or atomic-reviewer, and Claude falls back to the built-in Explore agent when asked to review atomic-agents code.

Fix

Switch to source: "git-subdir", which is what the 19 other subpath plugins in this marketplace already use (ai-firstify, aws-serverless, expo, pydantic-ai, neon, stripe, zapier, ui5, ui5-typescript-conversion, deploy-on-aws, amazon-location-service, dataverse, bigdata-com, helius, legalzoom, migration-to-aws, railway, semgrep, google-analytics). Keep the same path: "claude-plugin/atomic-agents" and add ref: "main" for tracking.

Also refreshes the description

The existing description reflects the retired v1.0.0 plugin layout ("specialized agents for schema design, architecture planning, code review, and tool development... guided workflows"). Plugin v2.0.0 shipped on 2026-04-16 as a skills-based architecture with two specialist read-only subagents (atomic-explorer for codebase mapping, atomic-reviewer for framework-specific review) plus the framework progressive-disclosure skill and the new-app scaffolder. Updated description matches the current plugin.json and CHANGELOG.md.

Verification

• JSON validates.
• Diff is minimal (one entry, five lines changed).
• Locally reproduced the original failure mode: with source: "url", the cache contains the full repo at cache/claude-plugins-official/atomic-agents/<sha>/ with the plugin nested three levels deep at cache/.../claude-plugin/atomic-agents/, which Claude Code does not resolve.
• The fix mirrors the working pattern of neighbouring entries. No other changes.
