Tools

• toolkit_encode_value ~614 tokens
  Encode or decode a value across base64, base64url, hex, or URL (percent) encoding, in either direction. Set operation to "encode" to transform raw UTF-8 text into the chosen encoding, or "decode" to recover the original bytes from an encoded value. Decoded bytes come back as UTF-8 text by default; s
• toolkit_generate_id ~386 tokens
  Mint cryptographically-random identifiers using the platform CSPRNG — the correct source for IDs that must be unpredictable, unlike model-generated values. type selects the format: uuid_v4 (random, the default), uuid_v7 (time-ordered, sortable by creation), or ulid (26-char Crockford-base32, lexicog
• toolkit_generate_qr ~720 tokens
  Encode text or a URL into a QR code. data is the content to encode (a link, a generated identifier such as toolkit_generate_id's ids[0], or any string). format selects the output: svg returns inline SVG markup sized in pixels, png_base64 returns base64-encoded PNG bytes (with mimeType and byteLength
• toolkit_geolocate_ip ~977 tokens
  Resolve a public IP or dotted hostname to country, region, city, coordinates, ASN, organization, timezone, and proxy/hosting/mobile flags. Supply target for one lookup or targets for an ordered batch, never both; blank target and empty targets are unset. Batches process the first 100 positions (dupl
• toolkit_hash_value ~873 tokens
  Generate a cryptographic digest of a value, or verify a value against an expected digest. Set operation to "generate" for a digest, or "compare" to constant-time-check value against the expected digest — compare is timing-safe and avoids manual string equality checks. Omitting operation compares whe
