Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| validate_usciA | Check whether an 18-character Unified Social Credit Identifier (USCI/USCC) from a mainland China business licence is well formed, and decode its segments. Offline arithmetic check per GB 32100-2015: verifies the character set and the mod-31 check character, and reports the registering authority, entity category and administrative division encoded in the code. Returns explicitly what a passing code does and does not establish. Does NOT query any registry and does NOT prove the company exists, is active, or is trustworthy. |
| usci_check_characterA | Compute the expected check character for the first 17 characters of a Unified Social Credit Identifier. Use when verifying a transcription: compute what the 18th character should be and compare it with what is printed. Offline; queries nothing. |

validate_usci performs full validation and decoding of an entire USCI, while usci_check_character computes only the check character for a partial code. Their purposes are clearly separated, with no practical confusion between validating a complete code and verifying a single digit.
The names follow different structural patterns: validate_usci is verb-noun, while usci_check_character is noun-noun (or noun-verb-noun) and reads more like an object than an action. Although both consistently use lowercase 'usci', the lack of a uniform verb-first convention prevents a higher score.
With only two tools, the server is slightly below the typical 3-15 range, but it targets a very narrow domain (offline USCI validation). Each tool has a distinct and necessary role, so the count feels reasonable even if minimal.
The server covers the core operations needed for offline USCI processing: full validation/decode and check-character computation. It explicitly declares it does not query registries, so the lack of a lookup tool is an intentional boundary rather than a gap, making the surface complete for its stated purpose.
