agents pull --format yaml succeeded silently and wrote JSON. The global --format flag is defined with .global(true) in src/app.rs:925-931, so clap accepts it on every subcommand, including the hand-written agents-as-code commands in cli/elevenlabs/workflow/, which never read it. Pulled configs are always raw wire JSON, so the flag read as if it controlled the on-disk format and did nothing.

Fix, three parts:

1. cli/elevenlabs/workflow/util.rs gains format_flag (next to dry_run_flag) and one shared helper, warn_format_ignored, called at the top of all six push/pull handlers (agents/tools/tests). The warning goes to stderr and the command still runs:

   --format controls how API responses are printed and has no effect on agents pull; agent configs are always written as JSON.
   

   I chose warn over error so scripts that already pass --format json for logging keep working; the flag is genuinely accepted by clap, so failing felt like a behaviour break. If you prefer a hard error, it is a two-line change in the same helper.

2. The global help now leads with the clarification: "Output format for printed API responses. Does not change files written to disk." I kept the remainder of the old help (format list, TTY default, <NAME>_OUTPUT env var, raw/jsonl/http descriptions) because that string is the only place those are documented. src/app.rs is hand-written (single author, not a Fern path), so I patched it directly.

3. The README "Agents as Code" section now states that configs are always stored as JSON.

Commands run: cargo test (839 passed), the types and sdk crate suites (38 and 118 passed), cargo check (clean). With the binary: agents pull --format yaml, --format yaml agents pull (flag before the subcommand), tools pull --format json, tests push --format csv, agents push --format json each print the warning on stderr and continue; without the flag there is no warning. Two unit tests cover format_flag after and before the subcommand.

Not covered: agents init/add/status warn nothing — they are typed handlers whose parsed args never see the global matches (src/app.rs:489-497), so warning there needs the framework to pass matches to typed handlers. Say the word and I will take that on. The message says "agent configs" on all six commands; for tools pull / tests push a per-family noun ("tool configs") would be more precise if you want it. Hiding --format from these subcommands' help is a possible follow-up.

Fixes #171.
