Stardew Valley SMAPI

When to Use This Skill

Use this skill for Stardew Valley modding tasks involving SMAPI or SMAPI-adjacent packaging:

• Creating or modifying a C# SMAPI mod.
• Writing ModEntry, Entry(IModHelper helper), event handlers, config, data, input, content, translation, multiplayer, or integration code.
• Creating, validating, or fixing manifest.json for a SMAPI mod or content pack.
• Diagnosing SMAPI build errors, load errors, runtime exceptions, missing dependencies, invalid JSON, asset issues, or player logs.
• Reviewing PC and Android compatibility for a mod.
• Preparing a SMAPI mod release package, update keys, Nexus/GitHub release notes, or compatibility statement.
• Deciding whether to use SMAPI APIs, Content Patcher/content packs, Reflection, or Harmony.

Do not use this skill for general Stardew Valley gameplay advice, non-modding C# questions, pixel art, story writing, or pure Content Patcher content.json syntax unless the task also involves SMAPI packaging, manifest, compatibility, or mod architecture.
