Stateless: send every answer collected so far on each call.\n\nProcedure: (1) Decide whether the repository already has real source code and set `isNewBuild` accordingly - it changes which onboarding analysis is generated at the end. (2) Infer what the repo already answers rather than asking: `platforms` from the dependency manifests and layout, `languageOverride`, `ideAgent` (you are the IDE - claudecode, cursor, copilot, codex, windsurf), `handle` from git config or the origin remote, `projectName` from the package manifest or folder name, and `projectDescription` from the README only if it plainly says what the project is. (3) Call this tool with what you have; answer what the repo makes obvious and ask the developer the rest, a whole step per message. Send an empty value for an optional question the developer declines, or it will be asked again; send `todoSentinel` verbatim when they do not know yet. For `projectDescription`, sending one of the returned chip labels exactly is what infers `projectCategory` and gates every later question - free prose infers nothing. Confirm any pre-seeded value rather than accepting it silently. (4) Loop until `done` is true, then call specpilot_generate_specs and follow its `nextSteps` for where each file goes.",
