What it does
Context7 Efficient is an agent skill from aiskillstore/marketplace. Token-efficient library documentation fetcher using Context7 MCP with 86.8% token savings through intelligent shell pipeline filtering. Fetches code examples, API references, and best practices for JavaScript, Python, Go, Rust, and other libraries. Use when users ask about library documentation, need code examples, want API usage patterns, are learning a new framework, need syntax reference, or troubleshooting with library-specific information. Triggers include questions like "Show me React hooks", "How do I use…
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts and reference files (for example `references/context7-tools.md`, `scripts/extract-code-blocks.sh` and `scripts/extract-notes.sh`).
It sits in Databases, covering ORMs and data access and React components. It works with Next.js, React, Prisma and Model Context Protocol. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Users ask about library documentation
- Need code examples
- Want API usage patterns
- Are learning a new framework
Example prompts
- “Show me React hooks”
- “How do I use Prisma”
- “s the Next.js routing syntax”
- “/context7-efficient”
Requirements
- Python 3
- A Bash shell
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Identify Library and Topic
- Fetch with Shell Pipeline
- Use Filtered Output
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 8 files in scripts/ (Shell and Python), which the agent can run.
Shell commands in SKILL.md call:
bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
anthropic.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Context7 Efficient loads about 1.5k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 159 tokens; SKILL.md has 448 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 448 words (~1,497 tokens).
“Fetch library documentation with automatic 77% token reduction via shell pipeline.”
