Might be worth taking over (with proper attribution) #7539 in a follow-up, I think the changes are largely similar.

287-289: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add context to value parsing errors.

Both parsing operations propagate errors without operation-specific context. Add .context(...) so the CLI reports whether attoFIL or human-readable value parsing failed.

Proposed fix
-        return Ok(TokenAmount::from_atto(BigInt::from_str(s)?));
+        let atto = BigInt::from_str(s).context("failed to parse attoFIL value")?;
+        return Ok(TokenAmount::from_atto(atto));
...
-    let amount = crate::cli::humantoken::parse(s)?;
+    let amount = crate::cli::humantoken::parse(s)
+        .context("failed to parse human-readable value")?;

As per coding guidelines, use anyhow::Result<T> and add .context() when errors occur.
