Tokens usage breakdown

What variant of Codex are you using?

cli

What feature would you like to see?

Add context token composition breakdown to /status (and optional statusline segment): show absolute tokens and percentage by source, including:

• system prompt total
• AGENTS.md (root/global/project) total
• MCP total, with per-tool breakdown
• tool calls total, with per-kind breakdown

Even a first version with just system prompt, AGENTS.md, and total MCP would already be very useful

Why:

• Makes context pressure explainable instead of opaque.
• Helps identify instruction/tool bloat early.
• Makes it easier to decide when to compact, split sessions, or disable heavy MCP/tool surfaces.
