  "how": {
    "incantation": "When an agent needs parseable output from a migrated `hf` command, rely on auto-detection or pass `--format agent`, `json`, or `quiet`. Use `agent` for untruncated TSV, `json` for structured output, or `quiet` for IDs only.",
    "examples": [
      "hf models ls --limit 5 --format agent",
      "hf models ls --search bert --limit 2 --json",
      "hf models ls --limit 5 --format quiet"
    ],
    "gotchas": [
      "Version: v1.9.0",
      "--format <value>: Select output format. Documented values: `auto` (default), `human`, `agent`, `json`, `quiet`. `auto` selects agent output when invoked by an AI agent; `agent` produces untruncated TSV, `json` structured JSON, and `quiet` IDs only. The docs do not say these values are mutually exclusive; they describe one selected format.",
      "--json: Alias for `--format json`.",
      "-q, --quiet: Alias for `--format quiet`; prints IDs one per line.",
      "--limit INTEGER: Limit the number of results returned.",
      "--search TEXT: Filter model list by search query.",
      "Prerequisite: Install the `huggingface_hub` package or the standalone `hf` CLI installer to use the CLI.",
      "Automatic detection and migrated output behavior are described for the listed commands; more commands are to be migrated later."

  },
  "why_it_matters": "Inspect Hub models, datasets, Spaces, papers, or authentication details from a coding-agent workflow that needs parseable CLI output.",
  "before": "The release note says output was designed for humans, with ANSI colors, padded tables, and truncated cells, making it harder for agents to parse.",
