  3. HARVEST - Extract context from summary files
  4. EXTRACT - Pull specific information from context
  5. COMPRESS - Reduce large file sizes
  6. ORGANIZE - Restructure context by concern
  7. CLEANUP - Remove stale or temporary files
  8. PROCESS - Guided workflow for context operations

Quick Start

Extracts key concepts from summary files into permanent context.

4. Extract Information

bash .opencode/skill/context/router.sh extract code-quality.md "naming conventions"

Pulls specific information from context files.

5. Compress Files

bash .opencode/skill/context/router.sh compress .opencode/context/ 100KB

Reduces large context files to save space.

6. Organize Context

  • Summary and next steps

Common Workflows

Workflow 1: Discover & Extract

1. discover context for: "authentication"
   → Find all auth-related context

2. extract from: "security-patterns.md" what: "auth patterns"
   → Get specific patterns

3. Show results
   → Ready to use in session

Workflow 2: Fetch & Reference

1. fetch external docs for: "Drizzle ORM"
   → Get live documentation

2. Show file paths
   → .tmp/external-context/drizzle-orm/...

3. Reference in session context
   → Add to "## External Context Fetched"

4. Pass to subagents
   → Include in subtask JSONs

Workflow 3: Harvest & Organize

1. harvest context from: "ANALYSIS.md"
   → Extract key concepts

2. organize context by: "concern"
   → Restructure for clarity

3. Update documentation
   → Show new structure

4. Delete original summary
   → Clean up temporary files

Workflow 4: Cleanup & Maintain

1. cleanup .tmp/ directory
   → Remove temporary files

2. cleanup external context older than: "7 days"
   → Remove stale external docs

3. Show space freed
   → Provide statistics

4. Update manifest
   → Keep tracking accurate

Key Principles

1. Lazy Loading

  • Discover files first (glob, grep)
  • Load only what's needed (read specific files)
  • Process incrementally (don't load entire repo)
  • Reference context files, don't duplicate

2. Clear Guidance

  • Explain what you're doing at each step
  • Show file paths and sizes
  • Provide before/after metrics
  • Suggest next steps
  • Ask for confirmation before destructive operations

3. Context Reference

  • When discovering: cite which files found
  • When processing: reference standards applied
  • When organizing: show which patterns used
  • When cleaning: explain what's being removed

4. Safe Operations

  • Ask for confirmation before destructive ops
  • Create backups when needed
  • Verify integrity after operations
  • Provide recovery instructions

Success Criteria

You succeed when: ✅ Context files are discovered efficiently ✅ External documentation is fetched and persisted ✅ Context is harvested from summaries ✅ Key information is extracted clearly ✅ Large files are compressed safely ✅ Context is organized by concern ✅ Stale files are cleaned up safely ✅ User has clear guidance at each step ✅ All operations are reversible ✅ Documentation is updated


Tips & Best Practices

1. Regular Discovery

Run discover operations regularly to understand your context structure and identify gaps.

2. Organize by Concern

Organize context by what you're doing (authentication, testing, etc.) not by function (standards, guides).

3. Lazy Load External Docs

Fetch external documentation only when needed, not preemptively.

4. Harvest Summaries

Convert temporary analysis documents into permanent context using harvest.

5. Regular Cleanup

Schedule regular cleanup operations to remove stale temporary files.

6. Validate After Changes

Always validate context integrity after making changes.

7. Document Organization

Keep navigation.md files up-to-date as you organize context.

8. Reference Standards

When extracting context, always cite the source files.


Troubleshooting

"Context files not found"

Run discover all context files to see what exists and where.

"External docs failed to fetch"

Check that the library name is correct and ExternalScout is available.

"Harvest created empty file"

The source file may not have enough high-signal content. Review and add manually.

"Organization failed"

Check that all referenced files exist and navigation.md is valid.

"Cleanup removed too much"

Check the backup at .backup/cleanup-{date}.tar.gz for recovery.
