Claude Code skills can be silently disabled due to context budget overflow

Claude Code skills are automatically listed in the AI model's context window on every turn, consuming a portion of a user's allocated context budget. This listing has a default budget of 1% of the context window, and when the combined listing of all installed skills exceeds this budget, descriptions are stripped from the least-used skills without any user notification. A skill without its description becomes invisible to the model, causing it to stop being used. A developer has created a command-line tool called 'skill-tax-cli' to audit this system, measure the token cost of all skills and other always-on sources, and predict which skills would be silently disabled. The tool is designed for integration into automated pipelines like CI/CD and pre-commit hooks.
