Does this work with other IDEs?

While optimized for Claude Code, Context Optimizer is part of the SpecWeave framework which supports Cursor and GitHub Copilot workflows.

When does the optimizer activate?

It activates automatically when your loaded context exceeds 20k tokens or when your prompt mentions specific features, bugs, or file paths.

How much can I save on token costs?

Most users achieve an 80% or higher total reduction in token usage when combining Context Optimizer with the standard SpecWeave context-loader.

Does it risk removing information I actually need?

The skill uses a high-confidence algorithm that defaults to keeping 'Broad' context if your prompt involves system-wide changes or architecture reviews.

Can I manually trigger an optimization pass?

Yes, you can manually trigger the skill by using phrases like 'optimize context', 'reduce tokens', or 'clean context' in your prompt.

Developer Tools

Reduces token usage by up to 80% through intelligent intent analysis and surgical removal of irrelevant context from Claude's workspace.

SpecWeave Context Optimizer is a high-performance efficiency tool designed to maximize the effectiveness of AI development sessions by managing context window saturation. While basic loaders pull in broad project files, this skill performs a sophisticated 'second-pass' analysis of your specific prompt to discard irrelevant specifications, agent descriptions, and domain-specific skills. By aligning the active context strictly with the current task's domain—such as isolating authentication logic during a login bug fix—it drastically lowers token consumption, minimizes API costs, and improves the precision of AI-generated solutions.

Key Features

01Domain-based filtering for backend, frontend, database, and infrastructure specs

02Real-time token savings reporting and optimization metrics

03Precision manual controls for 'smart cleanup' of active context

0413 GitHub stars

05Intelligent intent analysis to categorize tasks as bug fixes, features, or refactors

06Automatic activation for context windows exceeding 20,000 tokens

Use Cases

01Managing massive codebases in Claude by stripping out non-relevant documentation and skills

02Isolating specific module context during targeted bug fixes to prevent 'hallucinations' from unrelated code

03Optimizing long-running development sessions to stay within context window limits and reduce costs
