preamble-gate
preamble-gate is a PreToolUse hook that prevents Write, Edit, and MultiEdit operations from expanding always-loaded files (CLAUDE.md, ~/.claude/rules, MEMORY.md) beyond their token budgets; shrinking edits always pass to allow recovery from over-budget states. It measures token usage using trimwrit's estimate and blocks expansions while allowing configuration via project-level .trimwrit/budget.json or user-level ~/.claude/trimwrit-gates.json.
