Metadata and Tag Governance

lyra check-metadata supports both directory and single-file input, with automatic dedupe and optional AI-assisted tag generation.

# Check directory only (no write)
lyra check-metadata --path ../your-notes-repo

# Normalize tags (dedupe/trim/split delimiters)
lyra check-metadata --path ../your-notes-repo --fix-tags

# Normalize a single file
lyra check-metadata --path ./Input/Notes/today.md --fix-tags

# Normalize + AI enrich tags based on content
lyra check-metadata --path ../your-notes-repo --fix-tags --ai-tags --provider openai

Common options:

• --path <path>: directory or single Markdown file
• --fix-tags: normalize tags (dedupe, trim, delimiter cleanup)
• --ai-tags: generate/enrich tags from title and body content
• --max-tags <n>: max tags per file (default 8)
• --min-tags <n>: min tags per file (default 1)
• --dry-run: preview only, no write

Provider notes:

• openai: requires OPENAI_API_KEY
• anthropic: requires ANTHROPIC_API_KEY
• local: uses local model endpoint

Configuration Discovery

Lyra searches upward from current directory for these config files:

• .lyrarc
• .lyrarc.json
• .lyrarc.yaml
• .lyrarc.yml
• .lyrarc.js
• .lyrarc.cjs
• .lyrarc.mjs
• lyra.config.json
• lyra.config.js
• lyra.config.cjs
• lyra.config.mjs

Minimal Config Example

{
  "global": {
    "logLevel": "info",
    "defaultTemplate": "weekly"
  },
  "templates": {
    "weekly": {
      "enabled": true,
      "template": {
        "path": "./templates/weekly.hbs"
      },
      "sources": {
        "articles": "./articles",
        "tools": "./tools",
        "notes": "./notes"
      },
      "output": {
        "path": "./output",
        "filename": "Weekly-{{issueNumber}}.md"
      },
      "content": {
        "articles": { "topN": 10, "minRating": 0 },
        "tools": { "perCategory": 3 },
        "notes": { "groupBy": "none" }
      }
    }
  }
}

Versioning

Lyra follows semantic versioning (MAJOR.MINOR.PATCH):

• MAJOR: breaking changes
• MINOR: backward-compatible features
• PATCH: backward-compatible fixes

For frequent publishing, increment at least PATCH for every release.

Troubleshooting

Publish Config (Multi-Article + Module Matching)

• Prefer dedicated wechat.publish.json / zhihu.publish.json files
• Publish config should only include platform publish fields (AI follows .lyrarc.json)

{
  "lyraConfig": "./.lyrarc.json",
  "title": "Default Title",
  "author": "Lyra",
  "digest": "Default digest",
  "thumb_image_path": "./Output/Z° North/Publish/default-cover.png",
  "cover_source_order": ["ai", "unsplash", "placeholder"],
  "articles": [
    {
      "title": "Weekly #12",
      "module": "weekly",
      "contentFile": "./Output/Z° North/Z°N Weekly/drafts/2026-03-16-weekly.html"
    },
    {
      "title": "Life Notes",
      "contentFile": "./Output/Z° North/Z°N 生活志/drafts/2026-03-16-life.html"
    }
  ]
}

Publish command:

lyra publish --config ./wechat.publish.json

npm publish fails at prepublishOnly

If publish fails during npm run build with EPERM on dist, rebuild from clean state and check permissions:

rm -rf dist
npm run build

Config file not found

lyra init

Unexpected output quality

lyra weekly --dry-run --verbose
