context-and-tools CLAUDE.md

context-and-tools CLAUDE.md is an instructions file for coding agents from netlify/context-and-tools. It costs 667 tokens per session, scanned A, original, MIT.

Repository instructions for Netlify’s public context and tools, including platform guidance, skills, agent-plugin files, and generated rules for coding assistants.

In plain words
What is it for?
Use them when maintaining Netlify guidance, skills, plugin manifests, MCP configuration, or scripts that generate editor rules.
Why use it?
They help contributors keep platform references and generated outputs consistent across supported agent formats. They also identify which files are sources and which are generated.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

context-and-tools CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Netlify Context and Tools

This repository contains public Netlify skills — factual platform reference for AI agents working with Netlify projects.

Repository Structure

  • context/ — Steering guides (e.g., POWER.md for Kiro deployments)
  • .claude-plugin/ — Plugin marketplace config for Claude Code installation (VS Code agent plugins share this format and auto-detect .claude-plugin/plugin.json; no VS-Code-specific mirror is generated)
  • .grok-plugin/ — Plugin manifest for Grok Build (same plugin format as Claude Code; hand-authored, not generated)
  • .mcp.json — Netlify MCP server config bundled with the Claude Code and Grok Build plugins (hosted HTTP endpoint; OAuth at runtime)
  • skills/ — Netlify platform skills (source of truth for all agent formats)
  • agent-plugin/Agent Plugins spec-compliant package (plugin.json + mcp.json + skills/). Root manifests are hand-authored; agent-plugin/skills/ is auto-generated (do NOT edit directly)
  • cursor/rules/ — Auto-generated Cursor .mdc rule files (do NOT edit directly)
  • codex/ — Auto-generated Codex skills and AGENTS.md router (do NOT edit directly)
  • scripts/build-cursor-rules.sh — Converts skills/cursor/rules/
  • scripts/build-codex-skills.sh — Copies skills/codex/ and generates AGENTS.md
  • scripts/build-agent-plugin.sh — Mirrors skills/agent-plugin/skills/
  • .github/workflows/build-generated-outputs.yml — Rebuilds cursor/, codex/, and agent-plugin/skills/ from skills/ and commits them in a single step (on push to main and on PRs), so the generated mirrors always stay in parity with skills/

Skills

The skills/ directory contains skills covering Netlify platform primitives. See skills/CLAUDE.md for a guide on when to use each skill.

Cursor Rules

The cursor/rules/ directory is auto-generated from skills/ and must never be edited directly. A GitHub Actions workflow rebuilds these files whenever skills/ changes — committing them on same-repo PRs and on push to main (fork PRs are verified, not auto-committed). To rebuild locally:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
