Summary

• sim credentials providers now lists credential providers, the same request as sim credentials providers list (which keeps working)
• Agents consistently treat the providers group as the list (credentials providers | grep -i github) and got the group's usage text back instead of results, costing a retry
• New defaultSubcommand leaf flag: the leaf is registered as its group's default with Commander's native isDefault, so the group keeps no options of its own and the leaf parses its options in either spelling (credentials providers --search x and credentials providers list --search x). Variants never inherit it. Applied only to listCredentialProviders, whose group holds nothing but that list
• No other command, group, or generated doc changes (check:cli-docs and the docs compatibility check are unchanged)

Type of Change

• Improvement

Testing

• New packages/sim-cli/src/runtime/group-default.test.ts through runEmbeddedCli, capturing the real request: the bare group sends GET /api/v2/credentials/providers exactly as list does; --search github reaches the request as search=github in both spellings; a group without a default (credentials) still prints usage and sends nothing. 3/3 pass; the bare-group and option cases fail without the flag
• Related sim-cli suites (build, options, execute, commands, reference, embed isolation): 141 runtime + 19 contract tests pass
• bun run lint, check:cli-docs, check:cli-api, content:verify-compatibility, check:utils, check:comment-hygiene, check:test-patterns, check:explicit-any, check:file-names, check:source-conventions
• Type-check, full check:audits and the test suites run in CI

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
