[FEATURE] Remove skills from context when not in use.

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Skills are loaded into context and cannot be removed, even if they are definitely no longer needed.

Proposed Solution

Allow skills to be unloaded from context so they don't waste space acrosss a long conversation / workflow. Claude Code can often use multiple 'single-use' skills in a single session, which then sit around clogging context. It's wasteful and probably degrades quality.

Alternative Solutions

Building a plugin where claude creates a new file with it's entire context window minus whatever i want to prune, clears context, then loads the new file.

Priority

Medium - Would be very helpful

Feature Category

Performance and speed

Use Case Example

I begin a chat session asking for a gemini image, claude finds the compound-engineering image gen skill, makes me an image. then we move on to recreating the image in blender. Claude then removes the skill from context to keep it cleaner and more focused.
