munin-projectid

name	munin-projectid
description	Use when user says "/munin:projectid", "/projectid", or wants to set the current project ID for Munin memory system. Also use when MCP tools fail with "projectId is required" error.

Munin Project ID Skill

What I Do

I set or show the current MUNIN_PROJECT environment variable in the project's .env file (NOT in the global ~/.claude/settings.json). Using per-project .env files is required for multi-project workflows.

How to Use

Set project ID (per-project .env)

When user provides a project ID (e.g., /munin:projectid proj_my-project):

1. Confirm MUNIN_PROJECT should be set in the project directory's .env file.
2. Run: munin-claude env set MUNIN_PROJECT <projectId>
3. Confirm success with the output message.

Show current project ID

When user asks to show/check current project (e.g., /munin:projectid without value):

1. Run: munin-claude env get MUNIN_PROJECT
2. Report the current value or "not set" if null.
3. If the value comes from ~/.claude/settings.json, warn the user that this is deprecated and should be moved to the project's .env file.

Migration from settings.json (Deprecated)

If the user has MUNIN_PROJECT in ~/.claude/settings.json:

1. Read the current value: munin-claude env get MUNIN_PROJECT
2. Navigate to the project directory: cd ~/projects/my-project
3. Set it in the project's .env: munin-claude env set MUNIN_PROJECT <value>
4. Remove it from settings.json: edit ~/.claude/settings.json, remove the MUNIN_PROJECT entry from the env block.
5. Restart the Claude Code session.

Environment Variable Priority

Priority	Source
1 (highest)	Explicit MUNIN_PROJECT env var in shell
2	MUNIN_PROJECT in $PROJECT_DIR/.env.local
3	MUNIN_PROJECT in $PROJECT_DIR/.env
4 (deprecated)	MUNIN_PROJECT in ~/.claude/settings.json (warning emitted)

E2EE Projects — Hash Key Setup

If a project has encryptionEnabled: true or aiPoweredE2EE: true:

1. The Hash Key was set by the user in the WebUI during project creation.
2. Set it in the project's .env: munin-claude env set MUNIN_ENCRYPTION_KEY <user's-hash-key>
3. If the wrong key is set → all memory reads fail. Re-confirm with user.

Never Do

• Never store the Hash Key in ~/.claude/settings.json (shared across all projects).
• Each project with E2EE should have its own MUNIN_ENCRYPTION_KEY in its own .env.

Integration

This skill ensures MUNIN_PROJECT is available so all other Munin skills (memory, architecture, error-catalog) can function correctly.
