📝 WalkthroughWalkthroughThe change adds strict parsing for boolean environment variables, validates user and authentication configuration with Zod, updates subagent configuration typing, and expands tests and Codex-mode documentation. ChangesConfiguration validation and mode coverage
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to The PR hardens configuration parsing and preserves existing published behavior. The supplied feedback identifies only localized test and verification follow-up, with no demonstrated runtime, security, or availability issue; no actionable merge-blocking risk remains. Poem

Assert the complete changes tool surface.
The current test does not enforce that changes mode adds only show_changes. Compare its sorted tool names with the minimal-mode baseline plus exactly show_changes.

Greptile SummaryThe PR adds early validation for environment and persisted configuration while retaining supported defaults and forward-compatible top-level settings.
Confidence Score: 5/5The PR appears safe to merge, with no concrete changed-code failure identified. Supported persisted shapes, configuration precedence, feature defaults, and tool surfaces remain covered while malformed environment and file values now fail explicitly.

| Filename | Overview |
|---|---|
| src/env-config.ts | Adds a shared closed-vocabulary boolean parser that reports invalid environment values. |
| src/config.ts | Applies strict boolean parsing consistently across feature switches and logging options while preserving existing defaults. |
| src/user-config.ts | Validates persisted configuration and authentication files while preserving unknown top-level properties. |
| src/local-agent-config.ts | Exposes the stored subagent schema and validates the environment master override through the shared parser. |
| src/config.test.ts | Covers invalid environment values, persisted-file validation, legacy settings, and unknown-key passthrough. |
| src/server.test.ts | Adds integration coverage ensuring each configured tool and widget mode exposes the expected coherent surface. |
| docs/configuration.md | Removes the obsolete claim that Codex mode always uses fixed short names independently of tool naming. |

Closing this stacked review in favor of a single PR containing the complete runtime/config composition refactor. |
1 participant
DevSpace currently accepts some configuration values as loosely interpreted input: malformed booleans silently disable features, while persisted JSON is trusted through a TypeScript assertion. This hardens that boundary by decoding persisted configuration, rejecting invalid environment booleans, and preserving unknown persisted keys so newer config can survive an older binary.
This is the bottom PR in stack #227. It also locks the existing tool and presentation surfaces at the MCP boundary so the runtime refactor above it can remain behavior-preserving.
