claude-token-efficient

claude-token-efficient is a single-file configuration tool that reduces Claude's default verbosity by dropping a CLAUDE.md file into your project root. Claude Code reads it automatically, eliminating sycophantic preambles, unsolicited suggestions, and over-engineered responses. Benchmarks show up to 63% reduction in output word count with no signal loss, making it especially useful for automation pipelines and repeated structured tasks.

• Zero-setup drop-in: Copy CLAUDE.md to your project root via curl or git clone — no code changes, no configuration required.
• Eliminates sycophancy: Removes "Sure!", "Great question!", and closing fluff that adds tokens without value.
• Targeted edits over rewrites: Instructs Claude to prefer minimal, surgical code changes rather than rewriting entire files.
• Multiple profiles: Choose from CLAUDE.coding.md, CLAUDE.agents.md, CLAUDE.analysis.md, and CLAUDE.benchmark.md for different workflows.
• Versioned config sets: Three optimization strategies (v5 multi-file structured, v6 one-shot execution, v8 ultra-lean) let you tune cost vs. capability.
• Composable rules: Works with Claude's global (~/.claude/CLAUDE.md), project-level, and subdirectory-level file hierarchy so rules stay close to where they apply.
• Override-friendly: User instructions always win — ask for verbose output any time and the file won't fight you.
• Model-agnostic rules: Written as plain instructions; should work on any model that reads context, though benchmarks were run on Claude.
• Community-driven: Open to PRs and issue submissions; new fix rules are versioned and credited to contributors.
• Honest trade-offs documented: README explicitly states when the file costs more than it saves (low-volume, single-query, or fresh-session workflows).
