Feature: Tool call lifecycle
Scenario: Happy path lists the current directory through a tool
# This executable slice asserts the public exec stream and mocked LLM border.
# The PTY screen slice should also assert Statusline state and BlueWhale activity:
# running while the tool is executing, stopped or completed when the turn finishes.
Given an offline CodeWhale workspace containing:
| path | kind |
| README.md | file |
| notes.txt | file |
| src | folder |
And the mocked LLM will request the "list_dir" tool with:
| path |
| . |
And the mocked LLM will answer after the tool result:
| content |
| The directory contains README.md, notes.txt, and src/. |
When the user asks "list the current directory"
Then CodeWhale should send the user request to the mocked LLM
And the public tool lifecycle should show a running tool:
| status | marker | tool | input |
| running | [~] | list_dir | . |
And the public tool result should return directory entries:
| entry | kind |
| README.md | file |
| notes.txt | file |
| src | folder |
And CodeWhale should send the tool result back to the mocked LLM
And the public tool lifecycle should show a completed tool:
| status | marker | tool | input |
| completed | ✓ | list_dir | . |
And the public output should include "The directory contains README.md, notes.txt, and src/."
