The --model CLI flag now accepts provider/model format directly,
eliminating the need for a separate --provider flag. The Task tool's
model-resolver returns provider/model format, which the subprocess
CLI correctly parses.
Previously, subprocesses were passed --model gpt-5.2 without --provider,
causing the CLI to ignore the model and fall back to settings default.
Files referenced with @path/to/file.ext syntax are automatically read
and injected as synthetic Read tool calls before the agent responds,
eliminating the need for manual file reads.
- Write input file (.in.md) before spawning subprocess
- Use subtask-specific session file so pi writes jsonl in real-time
- Output file (.out.md) still written at completion (summary)
Enables observing/debugging running subagents via their session files.
message_update events contain full accumulated text, not deltas.
Previously appending them caused repeated content in artifacts and
progress display. Now message_update only updates progress display
(replacing, not accumulating) and message_end handles final output.
