fix: use snake_case for model-facing tool inputs - #303
Conversation
📝 WalkthroughWalkthroughThe change standardizes MCP tool inputs on snake_case names, updates handlers and instructions, adds schema and runtime coverage, and centralizes historical review payload construction. ChangesSnake_case tool inputs
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to Model-facing tool inputs now use snake_case while internal objects retain their existing camelCase representation. The supplied current-head evidence does not establish an active merge-blocking risk. Suggested reviewers: Poem

Greptile SummaryThis PR consistently changes model-facing MCP tool inputs from camelCase to snake_case while preserving camelCase internal objects, structured outputs, and workspace state.
Confidence Score: 5/5The PR appears safe to merge; the renamed MCP inputs are consistently mapped at the boundary and covered by schema and runtime tests. No actionable failures remain: internal camelCase contracts and structured outputs are preserved, all examined model-facing schemas and callers use snake_case, and historical review restoration matches the updated server contract.

Can you add one real ChatGPT E2E verification against this branch showing yield_time_ms reaches DevSpace unchanged and a ~15s command with a 30s yield returns completed? Also please call out that this intentionally changes the model-facing MCP input contract across tools, not just the affected yield field. make sure you attach the screenshots or share that chatgpt session |

whole PR looks slop to me, why the instructions and whole PR is written as if we have to make it backward compatible?
please rework on it

no need to change the older instructions
throughout this work, you should have just replaced the workspaceId with workspace_id
| `workspaceId`. Reuse that ID for work inside that worktree; call | ||
| `open_workspace` in worktree mode again only when another isolated worktree is | ||

wtf? why instructions are written as if they are trying to make it backward compatible?

This addresses the model-facing input naming part of #297. ChatGPT can mangle camelCase tool fields such as
yieldTimeMs, so DevSpace now exposes snake_case names at the MCP boundary while keeping its internal/domain objects and structured outputs in their existing camelCase form.This intentionally changes the model-facing MCP input contract across the core, Claude, Codex, and artifact tool surfaces; it is not a one-off alias or special case for the affected yield field. The handlers adapt snake_case back to the existing internal camelCase APIs. The historical
show_changesUI call andopen_workspaceinstructions are updated as well, so callers use the returnedworkspaceIdasworkspace_idon subsequent tool calls. The intermittent MCP disconnects described in #297 are intentionally not part of this PR.For head
0e78ad8on base8c5a501, the full test suite passed (109 tests, 104 passed, 5 platform-specific skips), TypeScript typechecking passed, the production build completed successfully, and the PR CI run passed. Upstreammainhas moved since that verification, so the latestmainstill needs to be integrated and the combined tree re-verified before merge.Summary by CodeRabbit
