Problem

wordsOf in shared/tool-name.ts splits a tool name only between a lowercase letter (or digit) and the capital after it. When a camelCase name has an initialism before the next word, the initialism and that word stay glued together:

readToolName("mcp__web__getHTMLContent")  // { label: "Get htmlcontent", detail: "web" }
readToolName("mcp__github__getPRDiff")    // { label: "Get prdiff", detail: "github" }
readToolName("listMCPServers")            // { label: "List mcpservers" }

So the step a person watches reads as a made-up word. wordsOf also breaks server keys into words for the "is the server already named in the label" check, so the same gluing can hide a match there.

Change

wordsOf adds one more split: between the last capital of an initialism and the capitalised word that starts after it (([A-Z]+)([A-Z][a-z])). This is the usual camelCase rule, and it only adds word breaks inside runs of capitals, so names that split correctly today split the same way. With it:

readToolName("mcp__web__getHTMLContent")  // { label: "Get HTML content", detail: "web" }
readToolName("mcp__github__getPRDiff")    // { label: "Get pr diff", detail: "github" }
readToolName("listMCPServers")            // { label: "List mcp servers" }

(HTML comes back in capitals because the existing word table already knows it.)

Proof

New case in app/tests/tool-name.test.ts. On unmodified main:

(fail) naming a tool call > an initialism in camelCase is its own word

With the change, the file passes (24 pass), and app/tests/tool-words.test.ts still passes (2 pass). I ran both with bun test against the shared sources directly, using absolute imports in place of the @openbot/shared and @/ aliases, since I did not install the workspace. biome format and biome lint --error-on-warnings on the changed files are clean.

AI assistance: I used an AI coding assistant to find and write this change, and reviewed and tested it myself.
