tail-test.sh

#!/usr/bin/env bash
# Tail the active fusion-skills test run and show tool calls in real time.
#
# Surfaces both raw tool names (Bash, Read, Edit, Skill, …) and — for Bash
# commands — the fusion-skills Python script being invoked (validate.py,
# action_search.py, import_workflows.py, trigger_workflow.py, etc.), so you can
# watch a workflow authoring/deployment run progress through the pipeline.
#
# Usage:
#   ./tail-test.sh              # Auto-detect the latest test log
#   ./tail-test.sh path/to.log  # Tail a specific log

# Each stream-json line may carry tool_use blocks. For every tool call, print:

# When the tool is Bash and the command runs a fusion-skills Python script,
# append "  ->  <script.py>" so the pipeline step is obvious at a glance.
