The user wants me to perform a sequence of operations using the `shell` tool.

Here is the plan:
1.  **Read the URL** from `challenge-url.txt`.
2.  **Fetch JSON** from the URL.
3.  **Parse the JSON** to get `nonce` and `payload`.
4.  **Calculate the proof**: SHA-256 of the string `<nonce>:<payload>`.
5.  **Create `web-proof.txt`** with the required format:
    *   `NONCE=<nonce>`
    *   `PAYLOAD=<payload>`
    *   `PROOF=<sha256_hex_of_nonce_colon_payload>`

**Step 1: Read the URL**
I will use `cat` to read the content of `challenge-url.txt`.

**Step 2 & 3: Fetch JSON and Parse**
I need a tool to fetch the URL and handle the JSON parsing. `curl` and `jq` (or similar) are usually available in a shell environment. I will use `curl` to fetch the data and pipe it to `jq` to extract the fields, or use `curl` and `jq` together.

**Step 4: Calculate the proof**
I need to use `echo` and `sha256sum` (or `openssl` if available) to calculate the hash.

**Step 5: Create the file**
I will use `echo` or redirection to write the final content to `web-proof.txt`.

Let's start by reading the file.

The previous attempt failed because `jq` was not found. I need to re-evaluate the plan and find a way to achieve the goal without relying on `jq`.

The goal is:
1. Read URL from `challenge-url.txt`. (Done)
2. Fetch JSON from that URL.
3. Extract `nonce` and `payload`.
4. Calculate `PROOF` as SHA-256 of `<nonce>:<payload>`.
5. Create `web-proof.txt`.

Since I cannot use `jq`, I must parse the JSON using standard shell tools like `grep`, `sed`, or `awk`, or by using `curl` to output the raw JSON and then parsing it.

The JSON structure is: `{"nonce":"...","payload":"..."}`.

I can use `curl` to get the raw JSON, and then use `grep` and `sed` to extract the values.

Let's try to fetch the JSON and extract the fields.

**Revised Plan:**
1. Read the URL from `challenge-url.txt`.
2. Fetch the JSON using `curl`.
3. Extract `nonce` and `payload` using string manipulation (e.g., `grep` and `sed`).
4. Calculate the proof using `echo -n` and `sha256sum`.
5. Create `web-proof.txt`.

Let's execute this.
