cowork-forge: Skill for Claude Code

Repomix Context Skill

Terrain stores a local repomix index at .terrain/agent/repomix.md (gitignored, fast to regenerate).

Read architecture first via terrain-knowledge-skill → .terrain/agent/context.md.

When to use

• Implementation details after reading context.md
• Cross-file symbol search within the indexed snapshot
• Locating handlers, types, routes

Query strategy (mandatory)

1. Read meta — .terrain/agent/meta.json (total_tokens, synced_at, top_files_by_tokens)
2. Search the pack — never load the entire file:

   # <rtk> = ~/.terrain/bin/rtk or bunx @terrain-ai/rtk (see rtk-skill)
   <rtk> grep "struct ProjectOverview" .terrain/agent/repomix.md
   <rtk> grep "### src/lib/api.ts" .terrain/agent/repomix.md
   

   Or agent Grep limited to that path with tight patterns.
3. Read slices — extract matching ### path/to/file sections only:

   <rtk> read .terrain/agent/repomix.md -l aggressive
   

   Then read the specific ### file block (line range), ≤150 lines per read.
4. Refresh — if meta.json.synced_at is stale, ask user to run Terrain 重建源码索引 / scan

Repomix section format

Sections look like:

### src/lib/foo.ts

\`\`\`typescript
... file content ...
\`\`\`

Grep for ### relative/path to jump to a file.

Paths

File	Purpose
.terrain/agent/repomix.md	Full indexed snapshot (local only)
.terrain/agent/meta.json	Pack metrics
.terrain/agent/context.md	Architecture (read first)

Do not

• Commit or assume repomix.md exists in git
• cat / Read the entire repomix.md (can be 100k+ tokens)
• Read the live repository tree when the pack covers the question
• Skip context.md and grep source for architecture questions

Regenerate index

If repomix.md is missing:

# bash / Git Bash — <terrain> = ~/.terrain/bin/terrain or bunx @terrain-ai/cli
if [ -x ~/.terrain/bin/terrain ] || [ -x ~/.terrain/bin/terrain.exe ]; then
  ~/.terrain/bin/terrain assets pack-agent .
else
  bunx @terrain-ai/cli assets pack-agent .
