TBLite drops the in‑progress transcript when it kills a timing‑out task. The events below were captured turn‑by‑turn by the agent‑loop patch and pieced back together — full content, reasoning, and tool calls are all real; they just came from a different stream than the other tasks.

I'll help you build this Merkle Tree CLI tool step by step. Let's start by creating the main Python file and setting up the basic structure.

→ write_file({"path": "/app/merkle_cli.py", "content": "import os\nimport json\nimport hashlib\nimport argparse\nfrom collections import deque\nfrom pathlib import Path\n\ndef sha512_hash(data):\n    \"\"\"Compute SHA-512 hash of data (bytes) and return 128-character hex string\"\"\"\n    return hashlib.sha512(data).hexdigest()\n\ndef file_hash(file_path):\n    \"\"\"Compute SHA-512 hash of a file's content\"\…)

Now let's create a test directory structure to test our tool. I'll create a test directory with some files and subdirectories.

→ terminal({"command": "mkdir -p /app/test_data/subdir"})

Great! The scan command worked and found 4 files (including the nested one). Let's verify that the merkle_data.json file was created correctly:

→ read_file({"path": "/app/merkle_data.json"})

Perfect! The merkle_data.json file was created with all the required information. Notice that all hashes are 128-character hex strings as required. Now let's test the proof command for one of the files:

→ terminal({"command": "python /app/merkle_cli.py proof file1.txt"})
