Cause (Documented platform behavior): With strict:false the entry must be the sole manifest; declaring components alongside plugin.json is a conflict. Entry hooks load only in inline object form when the entry is the manifest.

- not yet supported in a marketplace entry
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/plugins-reference (official_docs, unknown, documented_behavior): Plugins reference: with plugin.json present and strict:false, an entry declaring components fails with 'Plugin <name> has conflicting manifests'; entry hooks as file path/array show 'not yet supported in a marketplace entry'.

Proposed fix: [Claude Code plugins] 'Plugin <name> has conflicting manifests' — marketplace entry with strict: false declares components while plugin.json exists
Recommended action: Either remove component keys from the strict:false entry, drop strict:false (default true appends components), or remove plugin.json; use inline hooks object in marketplace entries.
Option: Either remove component keys from the strict:false entry, drop strict:false (default true appends components), or remove plugin.json; use inline hooks object in marketplace entries. [evidence: official_recommended_action]
Applies when: Installing a plugin whose marketplace.json entry sets strict: false and lists commands/agents/skills/hooks
Steps:
1. Decide which file is the manifest
2. If keeping plugin.json, remove strict:false or the component keys from the entry
3. Write entry hooks as an inline object
4. Run claude plugin validate
Expected: The error no longer appears.
