No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
base64 Base64 encode / decode (UTF-8 safe) ~203
Encode text or hex bytes to Base64, or decode Base64 / Base64url back to text. Binary-safe via UTF-8 so emoji and non-ASCII round-trip correctly. Supports standard (+ / with = padding) and URL-safe (- _ no padding) variants. Decoding auto-restores padding and falls back to raw hex if the bytes are not valid UTF-8. Runs entirely offline — same logic as the GeraTools Base64 tool.
| Name | Type | Req | Description |
|---|---|---|---|
| input | string | yes | The text/hex to encode, or the Base64 string to decode. |
| input_kind | string | – | When encoding, treat input as UTF-8 "text" (default) or "hex" bytes. |
| mode | string | yes | "encode" text→Base64, or "decode" Base64→text. |
| variant | string | – | Encode output: "std" (default) or "url" (URL-safe Base64url). Ignored when decoding. |
No output schema declared.
No examples provided.
css_unit_convert Convert a CSS length between units ~152
Convert a CSS length value from one unit to every other CSS unit (px, rem, em, pt, pc, in, cm, mm, Q). Absolute units use 1in = 96px; rem depends on root font size and em on parent font size (both default 16px). Offline — same logic as the GeraTools CSS Unit Converter.
| Name | Type | Req | Description |
|---|---|---|---|
| from | string | yes | The unit of the input value. |
| parent_font_px | number | – | Parent font size in px, used for em. Default 16. |
| root_font_px | number | – | Root font size in px, used for rem. Default 16. |
| value | number | yes | The numeric length value. |
No output schema declared.
No examples provided.
hash Cryptographic hash (MD5 / SHA-1 / SHA-256 / SHA-384 / SHA-512) ~150
Compute a cryptographic digest of the input using Node crypto — the same algorithms a browser SubtleCrypto produces. Input can be utf8 (default), hex, or base64; output as hex (default) or base64. Deterministic and offline. Note: MD5 and SHA-1 are provided for checksums/legacy interop only, not for security.
| Name | Type | Req | Description |
|---|---|---|---|
| algorithm | string | yes | Hash algorithm: md5, sha1, sha256, sha384, or sha512. |
| input | string | yes | The data to hash. |
| input_encoding | string | – | How to interpret the input bytes. Default utf8. |
| output_encoding | string | – | Digest output encoding. Default hex. |
No output schema declared.
No examples provided.
jwt_decode Decode a JSON Web Token (no signature verification) ~89
Base64url-decode a JWT into its header and payload JSON, list the iat/nbf/exp time claims as ISO timestamps, and report whether the token is expired. Does NOT verify the signature — never trust an unverified payload for authorization. Offline — same logic as the GeraTools JWT Decoder.
| Name | Type | Req | Description |
|---|---|---|---|
| token | string | yes | The JWT, e.g. "header.payload.signature". |
No output schema declared.
No examples provided.
regex_test Test a regular expression against a string ~129
Run a JavaScript regular expression against a test string and return every match (with index, capture groups and named groups), the match count, and a plain-English, token-by-token explanation of the pattern. Invalid patterns return the engine error rather than throwing. Offline — same logic as the GeraTools Regex Tester.
| Name | Type | Req | Description |
|---|---|---|---|
| flags | string | – | Regex flags, e.g. "gi". Default "g". (g is forced internally for enumeration.) |
| pattern | string | yes | The regular expression source (no surrounding slashes). |
| test_string | string | yes | The string to run the regex against. |
No output schema declared.
No examples provided.
word_count Count words, characters, sentences and reading time ~65
Analyse a block of text: word count, characters (with and without spaces), sentence count, paragraph count, line count, and estimated reading time (200 wpm). Offline — same logic as the GeraTools Word Counter.
| Name | Type | Req | Description |
|---|---|---|---|
| text | string | yes | The text to analyse. |
No output schema declared.
No examples provided.
