Plugin Manager

Unified plugin management skill that combines two capabilities:

1. Extension CRUD -- create, validate, version, and list plugin extensions within existing projects
2. Project Scaffolding -- scaffold entirely new plugin projects as local git repositories with language-specific tooling

Activation

This skill activates when:

• User invokes /aida plugin create
• User invokes /aida plugin validate
• User invokes /aida plugin version
• User invokes /aida plugin list
• User invokes /aida plugin scaffold
• User invokes /aida plugin update
• Routed from aida skill for any plugin operation

Operations

Operation	Mode	Description
create	Extension	Create plugin extension dirs/files
validate	Extension	Validate plugin.json metadata
version	Extension	Bump plugin.json version
list	Extension	List discovered plugins
scaffold	Scaffolding	Scaffold a full new plugin project
update	Migration	Scan and patch plugin to current standards

Path Resolution

Base Directory: Provided when skill loads via <command-message> tags containing the skill base directory.

Script Execution:

{base_directory}/scripts/manage.py

Templates:

{base_directory}/templates/extension/   # Plugin extension templates
{base_directory}/templates/scaffold/    # Project scaffolding templates

Two-Phase Workflow

Extension Operations (create / validate / version / list)

Phase 1: Gather Context

python {base_directory}/scripts/manage.py --get-questions \
  --context='{"operation": "create", "description": "..."}'

Returns questions and inferred metadata. The script auto-sets component_type to "plugin".

Phase 2: Execute

python {base_directory}/scripts/manage.py --execute \
  --context='{"operation": "create", ...}'

Creates, validates, versions, or lists plugin extensions.

Scaffold Operation

Phase 1: Gather Context

python {base_directory}/scripts/manage.py --get-questions \
  --context='{"operation": "scaffold", "plugin_name": "my-plugin"}'

Infers git config (author name/email), checks gh availability, and returns questions for missing fields (name, description, license, language, target directory, stubs, keywords).

Phase 2: Execute Scaffolding

python {base_directory}/scripts/manage.py --execute \
  --context='{"operation": "scaffold", "plugin_name": "my-plugin", "language": "python", ...}'

Creates a complete plugin project with:

• Directory structure (.claude-plugin/, agents, skills, docs)
• Metadata files (plugin.json, marketplace.json, aida-config.json)
• Documentation (CLAUDE.md, README.md, LICENSE)
• Language tooling (pyproject.toml or package.json, linters)
• Composite .gitignore and Makefile
• Optional agent and skill stubs
• Initialized git repository with initial commit

Update Operation

Phase 1: Scan and Report

python {base_directory}/scripts/manage.py --get-questions \
  --context='{"operation": "update", "plugin_path": "/path/to/plugin"}'

Scans the plugin directory against current scaffold standards. Returns a diff report with file-by-file comparison results categorized as: missing, outdated, up-to-date, or custom-skip.

The orchestrator should present the scan report to the user in this order:

1. Version context: scaffolded version vs current standard
2. Summary counts (missing, outdated, up-to-date, skipped)
3. Missing files (will be added)
4. Outdated files (will be updated per merge strategy)
5. Files flagged for manual review
6. Custom content files (will NOT be touched)
7. Merge strategy question (if boilerplate files need updating)

Phase 2: Apply Patches

python {base_directory}/scripts/manage.py --execute \
  --context='{"operation": "update", "plugin_path": "/path/to/plugin"}' \
  --responses='{"boilerplate_strategy": "overwrite"}'

Applies approved patches to the plugin:

• Creates backup at .aida-backup/{timestamp}/
• Adds missing files from templates
• Overwrites or skips outdated boilerplate per strategy
• Merges composite files (.gitignore, Makefile) append-only
• Skips custom content files (CLAUDE.md, README.md)
• Flags dependency configs for manual review
• Updates generator_version in aida-config.json

Present Results

After Phase 2 completes, present the results in this order:

1. Success message with old and new generator version
2. Files created (from files_created)
3. Files updated (from files_updated)
4. Files skipped (from files_skipped, brief)
5. Backup location (backup_path) if any files were modified
6. Manual steps required (manual_steps) -- present as a numbered checklist

File Categories

Category	Strategy	Files
Custom content	skip	CLAUDE.md, README.md,
		LICENSE
AIDA metadata	skip	aida-config.json
Plugin metadata	skip	plugin.json,
		marketplace.json
Boilerplate	overwrite	Linting configs, version
		files
Composite	merge	.gitignore, Makefile
CI workflows	add	.github/workflows/ci.yml
Test scaffold	add	tests/conftest.py
Dependencies	manual_review	pyproject.toml,
		package.json

Post-Scaffold: GitHub Repository (Optional)

If the user requested create_github_repo: true, the result includes this flag. Use the GitHub CLI to create the remote:

cd /path/to/my-plugin
gh repo create my-plugin --public --source=. --push

Plugin Validation Notes

Plugin validation is JSON-based (plugin.json), not frontmatter-based like agents and skills. The validation checks:

• name -- required, kebab-case, 2-50 chars
• version -- required, semver X.Y.Z
• description -- required, 10-500 chars

Error Handling

If Phase 2 returns {"success": false, ...}, report the message field to the user and offer to retry. The response includes path and files_created for any partial output.
