Patch Changes

• 9454412: Added --token-count, --token-limit, and --token-offset global options for token-aware output pagination. Uses LLM tokenization estimation (~96% accuracy via tokenx). In --verbose mode, truncated output includes meta.nextOffset for programmatic pagination.

Patch Changes

• 6ab9a33: Added --filter-output global option to filter output by key paths with support for dot notation and array slicing.
• 2dc1b00: Added --schema global option to every command that returns its JSON Schema (args, env, options, output).
• c60e6b8: Exposed format and formatExplicit on run and middleware context.
• 0e52ec0: Added cli.fetch to expose CLI as a standard Fetch API handler
• f5b0133: Added optional exitCode to c.error() and IncurError, allowing CLI authors to control the process exit code. Defaults to 1 when omitted (backward compatible).

Minor Changes

• 00b0b2d: Added Fetch API integration — mount any HTTP server as a CLI command.

  • Fetch gateway: .command('api', { fetch: app.fetch }) translates argv into HTTP requests using curl-style flags (-X, -d, -H, --key value query params)
  • Streaming: NDJSON responses (application/x-ndjson) are streamed incrementally
  • OpenAPI support: .command('api', { fetch, openapi: spec }) generates typed subcommands with args, options, and descriptions from an OpenAPI 3.x spec
  • Works with any framework exposing a Web Fetch API handler (Hono, Elysia, etc.)

Patch Changes

• e3aa038: Added dynamic shell completions for bash, zsh, fish, and nushell. CLIs get a built-in completions <shell> command that outputs a hook script. The hook calls back into the binary at every tab press, so completions stay in sync with commands automatically. Supports subcommands, --options, short aliases, enum values, and space suppression for command groups.
• 06580f0: Added short-alias stacking (e.g. -abc parsed as -a -b -c). The last flag in a stack can consume a value; all preceding flags must be boolean.

Patch Changes

• 3f7ca73: Added leading # to CTA command descriptions for easier copy-paste.
• 3f7ca73: Moved environment variables section to bottom of help output.
• 3f7ca73: Fixed invalid subcommand in a group falling through to root handler instead of returning COMMAND_NOT_FOUND. Added CTA with copyable help command to COMMAND_NOT_FOUND errors.
• 50282a8: Added redacted current value indicator for environment variables in help output.
• 79fbabd: Fixed streaming handler ignoring CLI-level and command-level default format. Previously, handleStreaming used only formatExplicit to decide between incremental and buffered mode, causing CLI defaults like { format: 'json' } to be ignored in favor of hardcoded 'toon'.
