Context Manager Skill

Purpose: Comprehensive context management operations with clear guidance, lazy loading, and safe operations for discovering, organizing, and maintaining project context.

What I Do

I provide 8 powerful operations for managing context:

DISCOVER - Find context files by topic or path
FETCH - Get external documentation from libraries
HARVEST - Extract context from summary files
EXTRACT - Pull specific information from context
COMPRESS - Reduce large file sizes
ORGANIZE - Restructure context by concern
CLEANUP - Remove stale or temporary files
PROCESS - Guided workflow for context operations

Quick Start

1. Discover Context

bash

bash .opencode/skills/context-manager/router.sh discover authentication

Finds all context files related to authentication patterns.

2. Fetch External Documentation

bash

bash .opencode/skills/context-manager/router.sh fetch "Drizzle ORM" "modular schemas"

Retrieves live documentation from external libraries.

3. Harvest Context

bash

bash .opencode/skills/context-manager/router.sh harvest ANALYSIS.md

Extracts key concepts from summary files into permanent context.

4. Extract Information

bash

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

Pulls specific information from context files.

5. Compress Files

bash

bash .opencode/skills/context-manager/router.sh compress .opencode/context/ 100KB

Reduces large context files to save space.

6. Organize Context

bash

Removes temporary or old files (older than 7 days).

8. Guided Workflow

bash

bash .opencode/skills/context-manager/router.sh process "organize authentication context" .opencode/context/

Step-by-step guidance for complex context operations.

Operations Reference

Operation 1: DISCOVER

Purpose: Find context files using intelligent discovery or direct search

When to Use:

Need to find all context files in repository
Looking for specific context by topic
Mapping context structure
Understanding what context exists

Syntax:

discover [target]

Examples:

bash

# Discover by topic
./router.sh discover "authentication patterns"

# Discover all context
./router.sh discover "all context files"

# Discover in specific directory
./router.sh discover ".opencode/context/core/"

Output:

List of discovered files with paths and sizes
File statistics (count, total size, last updated)
Categorization by type
Suggestions for next steps

Operation 2: FETCH

Purpose: Fetch external documentation using ExternalScout

When to Use:

Need live documentation from external libraries
Setting up new external library integration
Need version-specific documentation
Want to cache external docs for team

Syntax:

fetch [libraries] [topics]

Examples:

bash

# Fetch single library
./router.sh fetch "Drizzle ORM" "modular schemas"

# Fetch multiple libraries
./router.sh fetch "Drizzle ORM" "Better Auth" "Next.js" "modular schemas" "integration" "app router"

# Fetch with specific query
./router.sh fetch "Better Auth" "Next.js App Router integration with Drizzle adapter"

Output:

Fetched files with paths
File sizes and statistics
Source URLs
How to reference in context
Manifest updates

Operation 3: HARVEST

Purpose: Extract context from summary files and create permanent context

When to Use:

Have summary documents that should become context
Need to convert temporary notes to permanent context
Want to extract key concepts from larger documents
Need to organize scattered information

Syntax:

harvest [source-file]

Examples:

bash

# Harvest from analysis
./router.sh harvest DEVELOPER_PROFILE_ANALYSIS.md

# Harvest from brainstorm
./router.sh harvest AGENT_NAMING_BRAINSTORM.md

# Harvest from UX analysis
./router.sh harvest UX_ANALYSIS_THREE_MAIN_AGENTS.md

Output:

Created context file path
Space saved (original vs. harvested)
Content structure
Updated navigation files
How to use the new context

Operation 4: EXTRACT

Purpose: Extract specific information from context files

When to Use:

Need specific information from context
Creating summaries or reports
Building context bundles for subagents
Validating context completeness

Syntax:

extract [file] [what-to-extract]

Examples:

bash

# Extract naming conventions
./router.sh extract code-quality.md "naming conventions"

# Extract test patterns
./router.sh extract test-coverage.md "test patterns"

# Extract all standards
./router.sh extract ".opencode/context/core/" "all standards"

Output:

Extracted information organized by topic
Source file citations
Relevance scores
Usage suggestions
Next steps

Operation 5: COMPRESS

Purpose: Compress large context files to save space

When to Use:

Context files are very large (>100 KB)
Need to reduce disk space usage
Archiving old context
Preparing context for distribution

Syntax:

compress [target] [size-threshold]

Examples:

bash

# Compress large files
./router.sh compress ".opencode/context/" "100 KB"

# Compress all context
./router.sh compress ".opencode/context/"

# Compress and archive
./router.sh compress ".opencode/context/development/" "50 KB"

Output:

Compressed files with paths
Space savings (before/after)
Compression ratio
Decompression instructions
Manifest updates

Operation 6: ORGANIZE

Purpose: Reorganize context files by concern (what you're doing) rather than function

When to Use:

Context is scattered across multiple locations
Need to reorganize by concern/topic
Creating new context structure
Consolidating related context

Syntax:

organize [target]

Examples:

bash

# Organize by concern
./router.sh organize ".opencode/context/"

# Organize specific topic
./router.sh organize ".opencode/context/development/"

Output:

Current structure analysis
Proposed new structure
Files moved and reorganized
Updated references
Navigation updates
New structure overview

Operation 7: CLEANUP

Purpose: Clean up stale, temporary, or unused context files

When to Use:

Removing temporary files (.tmp/)
Deleting old external context (>7 days)
Removing duplicate context
Archiving unused context

Syntax:

cleanup [target] [older-than-days]

Examples:

bash

# Cleanup .tmp directory
./router.sh cleanup ".tmp/"

# Cleanup old external context
./router.sh cleanup ".tmp/external-context/" "7"

# Cleanup stale sessions
./router.sh cleanup ".tmp/sessions/" "3"

Output:

Files to be deleted
Space to be freed
Impact analysis
Recovery instructions
Manifest updates

Operation 8: PROCESS

Purpose: Provide guided workflow for processing context

When to Use:

Need step-by-step guidance on context operations

Syntax:

process [goal] [scope]

Examples:

bash

# Process authentication context
./router.sh process "organize authentication context" ".opencode/context/development/"

# Process all development context
./router.sh process "organize all development context" ".opencode/context/development/"

# Process external context
./router.sh process "fetch, persist, and reference external context" ".tmp/external-context/"

Output:

Step-by-step workflow
Progress indicators
Discovered context
Processing plan
Execution results
Validation results
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.
