Plugin pages in /usage now show how much of the system prompt context budget each plugin's skills consume, broken down per skill.
Details
- Shown under "Skill-listing footprint" — the cached input cost after the first turn, before agents and MCP tools are counted
- Lists each skill with its approximate token cost per turn, sorted by size
- Footer note: "For per-skill invocation counts and cost attribution, see /usage"
- When no model-invocable skills are loaded for a plugin, shows "No model-invocable skills loaded for this plugin"
Evidence
New skill footprint UI (search for "Skill-listing footprint" or "What this plugin's skill descriptions add to the system prompt")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
