Localize Skill Descriptions

Purpose

Document the correct workflow for localizing skill descriptions (or any skill metadata) while protecting local modifications from being overwritten by git pull.

This skill applies to any skills installed via git repositories in AI coding assistants (OpenCode, Claude Code, etc.).

Problem Context

When you want to customize skill descriptions (e.g., translate to Chinese, add custom tags, modify triggers) for skills installed via a git repository, you face a conflict:

• git pull updates will overwrite your local changes
• Creating duplicate files means maintaining two copies
• Using --assume-unchanged is dangerous — git may still overwrite those files

Correct Workflow

Step 1: Modify files in the git repository

Edit the SKILL.md files directly in the git-tracked directory.

# Example: Translate description to Chinese
cd ~/.config/opencode/superpowers
for skill in skills/*/SKILL.md; do
  # Edit the description field in YAML frontmatter
  sed -i '' 's/old description/新描述/' "$skill"
done

Step 2: Protect local changes with skip-worktree

cd ~/.config/opencode/superpowers
git update-index --skip-worktree skills/*/SKILL.md

This tells git to ignore local changes to these files during git pull, git checkout, etc.

Step 3: Create symlink for skill discovery

If the skill discovery mechanism scans a different directory than the git repo, create a symlink:

ln -s ~/.config/opencode/superpowers/skills ~/.config/opencode/skills/superpowers

This avoids duplicating files — the symlink points to the git repo, which already has your localized descriptions.

Common Mistakes

WRONG: Creating duplicate files

# Don't do this — you now maintain two copies of each file
cp ~/.config/opencode/superpowers/skills/*/SKILL.md ~/.config/opencode/skills/

WRONG: Using assume-unchanged

# Don't use --assume-unchanged — it's for performance optimization, not local overrides
git update-index --assume-unchanged skills/*/SKILL.md

CORRECT: skip-worktree + symlink

# Modify in-place, protect with skip-worktree, symlink for discovery
git update-index --skip-worktree skills/*/SKILL.md
ln -s ~/.config/opencode/superpowers/skills ~/.config/opencode/skills/superpowers

Key Differences: skip-worktree vs assume-unchanged

Flag	Purpose	Safe for local overrides?
--skip-worktree	"I modified this locally, don't touch it"	✅ Yes
--assume-unchanged	"This file is huge, skip checking it for performance"	❌ No — git may overwrite it

Verification

# Verify skip-worktree status (S = skip-worktree set)
git ls-files -v skills/*/SKILL.md | grep '^S'

# Verify working tree is clean
git status

# Verify symlink exists
ls -la ~/.config/opencode/skills/superpowers

Rollback

To restore tracking:

git update-index --no-skip-worktree skills/*/SKILL.md
git checkout -- skills/*/SKILL.md  # restores upstream version

Lessons Learned

1. Never duplicate files — always modify in-place and protect with skip-worktree
2. skip-worktree ≠ assume-unchanged — they serve different purposes
3. Symlinks are your friend — use them for discovery mechanisms instead of copying
4. Verify before trusting — always run git status and git ls-files -v after setup
5. SKILL.md 必须有 YAML frontmatter — OpenCode 通过 --- 块中的 name 和 description 字段发现和展示技能。没有 frontmatter 的技能不会出现在 /skill-name 命令列表中。

YAML Frontmatter 格式

---
name: your-skill-name
description: 简短描述技能用途和触发条件（会被 OpenCode 展示给用户）
---

错误路径：直接写 # Skill Title 开头，没有 frontmatter → 技能不被发现。 正确路径：文件必须以 --- 开头，包含 name 和 description。
