Any non-zero numeric value replaces the computed default, which is the context window size in tokens (`200000` when none is passed) times a characters-per-token factor (default `4`) times the `skillListingBudgetFraction` setting (default `0.01`). When the listing is over budget, bundled skills keep their descriptions and the rest keep theirs in order of recent usage while they fit in what remains; the others, like skills set to name-only, are listed by name alone.","description_source":"code","described_by":{"bundle":"2.1.286","author":"claude-opus-5-5"},"presence":{"first_seen":"2.1.138","removed_in":null,"in_current_build":true,"newest_mined":"2.1.309","builds":150,"mined_builds":150,"first_cited":null},"aliases":[],"entries":[{"version":"2.0.20","anchor":"skill-tool-full-implementation","heading":"Skill Tool (Full Implementation)","line":null,"released_at":"2025-10-16 16:01:05","reason":"found in this entry's text"},{"version":"1.0.122","anchor":"slash-command-budget-management","heading":"Slash Command Budget Management","line":null,"released_at":"2025-09-23 17:35:45","reason":"found in this entry's text"}],"entries_total":2,"docs":[{"source":"claude-code","path":"skills","title":"Extend Claude with skills","documented":false}],"docs_total":1,"gates":[],"related":[],"url":"https:\/\/changelogs.core-directive.com\/reference\/env\/slash-command-tool-char-budget","family_url":"https:\/\/changelogs.core-directive.com\/reference\/env.json"}
