class-skill-regen

You are an ESO class skill data assistant. You update the TypeScript skill-line files in src/data/skill-lines/class/ by fetching skill descriptions and icons from the ESO-Hub JSON API via a project script, rather than scraping individual pages.

How It Works (API-Based, Efficient)

ESO-Hub exposes a JSON API that returns all skills paginated (100 per page, 10 pages = ~1000 skills). The script scripts/refresh-class-skills.mjs fetches all pages, filters to the 7 class categories (462 skills), compares against local TypeScript files, and applies description + icon updates automatically.

This requires only ~10 HTTP requests instead of hundreds of browser navigations.

What Gets Updated vs What Doesn't

Quick Commands

# Diff only -- see what has changed without writing anything
node scripts/refresh-class-skills.mjs

# Apply all changed descriptions and icons to TypeScript files
node scripts/refresh-class-skills.mjs --apply

# Diff a single skill line (use the URL slug, e.g. ardent-flame)
node scripts/refresh-class-skills.mjs --line ardent-flame

# Apply changes to a single skill line
node scripts/refresh-class-skills.mjs --apply --line ardent-flame

  boneTyrant.ts           -- Necromancer: Bone Tyrant        (bone-tyrant)
  graveLord.ts            -- Necromancer: Grave Lord         (grave-lord)
  livingDeath.ts          -- Necromancer: Living Death       (living-death)
  heraldOfTheTome.ts      -- Arcanist: Herald of the Tome   (herald-of-the-tome)
  curativeRuneforms.ts    -- Arcanist: Curative Runeforms    (curative-runeforms)
  soldierOfApocrypha.ts   -- Arcanist: Soldier of Apocrypha (soldier-of-apocrypha)

Note: The --line flag uses the URL slug from ESO-Hub (e.g., dawns-wrath, winters-embrace). These may differ slightly from the local filename -- the script normalises apostrophe-containing slugs automatically.

Step-by-Step: Full Refresh

1. Run the diff to see what needs updating

node scripts/refresh-class-skills.mjs

Read the summary output:

• Descriptions changed -- skills that exist locally but have different description text on ESO-Hub
• Icons changed -- skills where the ESO-Hub icon name differs from the local value
• New skills on API -- skills on ESO-Hub not yet in any local file (morphs from a new patch; need manual addition)
• Unknown slugs -- skill-line slugs from the API that don't match any local file (usually indicates a new class skill line)

The full diff is also saved to tmp/class-skill-refresh-report.json for review.

2. Apply description and icon updates

node scripts/refresh-class-skills.mjs --apply

This rewrites each skill's description and icon field in-place, preserving the surrounding TypeScript structure (IDs, types, morph relationships, etc.).

3. Validate

npm run typecheck 2>&1 | Select-String "error" | Select-Object -First 20

Fix any syntax errors before proceeding.

4. Handle new skills or morphs manually

If a patch adds a new skill or morph, the script report flags them in the "New skills on API" section. You must add these manually following the existing pattern in the relevant file:

{
  id: ClassSkillId.MyNewSkillId,
  name: 'My New Skill',
  type: 'active',
  icon: 'ability_class_skill_icon',
  description: 'The full description text from ESO-Hub.',
  isPassive: false,
  isUltimate: false,
  baseSkillId: ClassSkillId.BaseSkillId,
},

New skill numeric IDs must first be added to src/features/loadout-manager/data/classSkillIds.ts. Use the skill-data-regen skill for guidance on that process.

API Reference

• Endpoint: https://eso-hub.com/api/search/skills?lang=en&all=1&page=N
• Pages: 10 total (100 skills per page)
• Class categories: Arcanist, Dragonknight, Necromancer, Nightblade, Sorcerer, Templar, Warden
• Join key: skillLine.url last path segment (slug) matches the sourceUrl last path segment in local files
• Icon field: Full URL like /storage/icons/ability_dk_003.png -- strip path and extension -> ability_dk_003
• Description field: html property (contains HTML tags) -- script strips tags and decodes entities
