Context X-Ray
SkillAI & modelscontext-xray is a skill that lets your AI analyze how much context your local Codex and Claude Code sessions use. Once added, your AI can visualize that usage, open a report, flag warnings, and suggest ways to optimize your prompts and tooling. The result is a clear picture of what is filling up your context and what to change.
Available today. Use it from your connected AI after setup.
No other account needed.
After adding it, ask your AI to analyze the context usage of your Codex or Claude Code sessions and open the report. Then try its suggestions for improving prompts or tooling.
Then ask your AI: use the Context X-Ray skill
What your AI can do with it
- Visualize how much context your local Codex and Claude Code sessions use
- Open a report on context usage
- Flag warnings about context usage
- Suggest prompt optimizations
- Suggest tooling optimizations
What this skill tells your AI
The instructions your AI receives, as published by builderio/agent-native in skills/context-xray/SKILL.md and read by ahel’s review.
Use Context X-Ray when a local coding-agent thread is getting large or the user wants to understand where context is going.
Setup
Recommended install path:
npx @agent-native/core@latest skills add context-xray --client all
That installs a local context-xray command plus Codex/Claude skills and slash
commands. It does not need hosted auth or a remote MCP connector to read local
transcript files.
Use --scope project when you only want project .agents skill and command
artifacts added to the current repo.
Run
Current or most recent local thread:
context-xray --open
Recent thread picker:
context-xray threads --open
Weekly trends:
context-xray trends --since 7d --open
--open opens the generated local HTML file directly in the browser; it does
not keep a background server running.
After running, summarize the report link, sessions analyzed, largest context buckets, warnings, and concrete optimizations.
