When the server runs with no default project to fall back to — a gateway
server started outside any repo, or a monorepo root whose .codegraph/
indexes live only in sub-projects — every tool call must carry an explicit
projectPath. Previously projectPath was always optional, so an agent talking
to such a server would omit it, get success-shaped "pass projectPath"
guidance, and not reliably retry; the user had to nudge it by hand.
getTools() now marks projectPath required in the exposed tool schemas on the
no-default-project branch (a high-salience channel clients surface/validate,
unlike the instructions prose the reporter found too weak). When a default
project is open, projectPath stays optional and a bare call falls back to it.
The fix lives at the MCP schema layer, not the Claude-only front-load hook:
the hook is local-filesystem-based and never runs for the reporter (they're
on AGENTS.md / Codex-opencode). The proxy/getStaticTools path is untouched —
index.ts forces direct mode whenever resolveDaemonRoot is null, so the
no-default case never reaches the proxy.
