Asta Artifacts

Artifacts are the structured outputs produced by A2A agents. They accumulate in the artifacts[] field of the task response.

Export

# 1. Dump task result
TASK_DIR=$(mktemp -d)
asta <agent> task "<TASK_ID>" > "$TASK_DIR/task.json"

# 2. Export (caller decides output dir and format)
asta artifacts --input "$TASK_DIR" --output "$OUT_DIR" --format md

Produces per-artifact files organized by subtype, plus index.md, references.bib, and manifest.json.

Works on partial task data too — useful for previewing mid-run.
