10831083The Skills row in `/context` reports the size of the listing after the budget is applied, so it matches what the model receives. Before v2.1.196, the row counted the full text of every description and could show a value several times larger than the configured budget.

1085To raise the budget, set the [`skillListingBudgetFraction`](/docs/en/settings-reference#skilllistingbudgetfraction) setting (e.g. `0.02` = 2%) or the `SLASH_COMMAND_TOOL_CHAR_BUDGET` environment variable to a fixed character count. To free budget for other skills, set low-priority entries to `"name-only"` in [`skillOverrides`](#override-skill-visibility-from-settings) so they list without a description. You can also trim the `description` and `when_to_use` text at the source: put the key use case first, since each entry's combined text is capped at 1,536 characters regardless of budget. The cap is configurable with [`skillListingMaxDescChars`](/docs/en/settings-reference#skilllistingmaxdescchars).
