Plugin Data Convention

Standard convention for plugins that create files in user projects.

Path Convention

.claude/plugin-data/<plugin-name>/<data-type>/

Plugins creating files in user projects MUST use this path structure.

Examples

Plugin Path Purpose
ux .claude/plugin-data/ux/audits/ UX audit findings
seo-audit .claude/plugin-data/seo-audit/reports/ SEO audit reports
commit .claude/plugin-data/commit/history/ If commit needed state

File Naming

Use descriptive, sortable names:

<date>-<type>-<subject>.md

Examples:

  • 2024-01-15-heuristic-checkout-flow.md
  • 2024-01-15-accessibility-homepage.md
  • 2024-01-15-report-full-audit.md

Gitignore

User projects should add to .gitignore:

.claude/plugin-data/

This data is transient and project-specific. It should not be committed.

For specific plugin types, consider more granular patterns:

# Temporary files
**/.claude/plugin-data/<plugin-name>/tmp/

# Cached data
**/.claude/plugin-data/<plugin-name>/cache/

# Log files
**/.claude/plugin-data/<plugin-name>/*.log

Artifact Lifecycle

When designing functionality that creates plugin data files, consider cleanup needs.

Lifecycle Types

Type Example Recommended Approach
Audit findings UX heuristic evaluation Manual cleanup, historical value
Temporary state In-progress work Auto-archive or TTL-based cleanup
Reports SEO audit summary Archival policy, version-dated

Documentation Requirements

  1. In the skill/workflow: Document expected lifecycle of created artifacts
  2. In plugin CLAUDE.md: Add cleanup guidance section

Plugin Author Checklist

When your plugin creates files in user projects:

  • Use .claude/plugin-data/<plugin>/ path
  • Choose semantic subdirectory name (audits/, reports/, state/)
  • Document cleanup expectations in workflow
  • Consider if automated cleanup is warranted
  • Add note to generated files about their transient nature
  • Include cleanup guidance in plugin CLAUDE.md
