## Tools (as reported by the server, not verified)

- `encode\_base64`: Encode UTF-8 text as standard Base64 \(padded, A-Z a-z 0-9 + /\), for embedding binary-unsafe content in JSON, data URIs, HTTP headers or Basic auth. Returns JSON \{ encoded \}. The output uses the standard alphabet, so it is NOT URL-safe: '+' and '/' must still be percent-escaped before they go in a qu
- `decode\_base64`: Decode a Base64 string back to UTF-8 text. Returns JSON \{ decoded \}. Input is verified by re-encoding, so anything that is not genuine Base64 is rejected with an error instead of returning plausible garbage; binary payloads that are not valid UTF-8 will also fail. It handles Base64 and nothing else:
- `decode\_jwt`: Decode a JWT's header and payload for inspection. Returns JSON \{ header, payload, signatureVerified, note, expiresAt, isExpired \} — structured objects, not a rendered table. The signature is NEVER verified: that needs the issuer's key, which this service does not have, so signatureVerified is always
- `format\_json`: Validate and re-print a JSON string. Returns JSON \{ valid, formatted, minified \} — the indented form and the whitespace-free form as plain strings, with no syntax highlighting or colour. Invalid JSON is rejected with the parser's own error message rather than returned as valid:false, so a successful
- `calculate\_percentage`: Run one of four percentage calculations on two numbers. Returns JSON \{ operation, result \} \(plus unit: 'percent' for the 'change' operation\). The meaning of value1 and value2 depends on the operation, so read their descriptions before calling. Exact arithmetic, no model involved, no rounding applied
