Is the Context Optimizer skill free?

Yes. The skill itself is free from rohitg00/pro-workflow. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Context Optimizer SkillProof Score?

8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 4/5.

How do I install Context Optimizer?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Context Optimizer with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Fetched the repo tree (a 40+ skill monorepo) and the raw skills/context-optimizer/SKILL.md. Frontmatter parses with name+description; body references only Claude Code builtins (/context, /compact, /mcp, /resume) — no broken relative links, no scripts, no hardcoded paths, no exfiltration or base64. Content is concrete: compaction thresholds (70%/90% "dumb zone"), a per-phase context budget table, MCP<10/tools<80 heuristic, and output-reduction rules.

What Context Optimizer does

A pure-prompt skill that tells Claude how to manage its own context window and cut token usage: when to /compact (>70%), how to delegate heavy output to subagents, MCP/tool-count budgets, and output-reduction rules. Triggers when a session feels slow, context is degraded, or the token budget is running low.

How to install Context Optimizer

Copy the `skills/context-optimizer/` folder into your `.claude/skills/` directory (project or `~/.claude/skills/`). Single self-contained SKILL.md, no scripts or dependencies.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Context Optimizer

/context-optimizer Concrete thresholds and commands for managing Claude's context window and token budget

It also activates on plain-language prompts like these:

This session feels slow, optimize my context
Trim unnecessary context before I run out of budget
Help me reduce token usage in this conversation
