Token Efficient
Documentstoken-efficientToken Efficient is an Agent Skill for documents published in the majiayu000/claude-skill-registry repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Use when processing 50+ items, analyzing CSV/log files, executing code in sandbox, or searching for tools. Load for data processing tasks. Achieves 98%+ token savings via in-sandbox execution, progressive disclosure, and pagination. Supports heredocs for multi-line bash.

How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/majiayu000/claude-skill-registry/blob/HEAD/skills/data/token-efficient-ingpoc-skills-2/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/token-efficient, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
Token-Efficient MCP
Process data in sandbox, return only results. 98%+ token savings.
Instructions
- Search for tool:
search_tools("csv")(95% savings vs loading all) - Process data in sandbox (never load raw to context)
- Use pagination for large files:
offset,limit - Return summaries, not raw data
Quick Commands
# Process CSV with filter
scripts/process-csv.sh data.csv "price > 100"
# Search logs for errors
scripts/search-logs.sh app.log "ERROR|WARN"
# Execute code in sandbox
scripts/run-sandbox.sh script.py
