Greptile SummaryThis PR adds an opt-in Codex network-access setting and propagates it from persisted configuration through daemon driver construction into workspace-write turn policies.
Confidence Score: 4/5The PR should not merge until the published configuration schema enforces the same Codex-only constraint as runtime validation. The policy propagation and restart behavior are consistent, but the generated schema approves non-Codex configurations that the application rejects when loading. Files Needing Attention: schema/v1/devspace.schema.json and its schema-generation source
|
| Filename | Overview |
|---|---|
| src/local-agent-config.ts | Adds optional boolean parsing and correctly restricts the setting to Codex during runtime validation. |
| src/local-agent-daemon-main.ts | Reads the Codex provider setting at daemon startup and forwards it into driver construction. |
| src/local-agent-codex.ts | Carries network access into new and resumed workspace-write turn policies while preserving other sandbox modes. |
| schema/v1/devspace.schema.json | Adds the setting but exposes it to every provider, diverging from the Codex-only runtime constraint. |
| src/local-agent-codex.test.ts | Covers omitted, false, and true values across sandbox modes and new or resumed sessions. |

The shared provider schema allows networkAccess for every provider, but runtime validation only allows it for Codex. As a result, an editor or CI validator can approve a non-Codex configuration that the application then rejects while loading. Please encode the Codex-only constraint in the generated schema.

Reject networkAccess for non-Codex providers in the JSON Schema.
This schema adds networkAccess to every provider object. The Zod schema rejects the field unless id is "codex". A JSON Schema consumer can therefore accept { "id": "claude", "networkAccess": true }, while DevSpace later rejects it.
Add a conditional or provider-specific oneOf so both schemas enforce the same contract.

Codex subagents currently receive a workspace-write sandbox policy without network access, so tasks that fetch dependencies or call an HTTP endpoint fail even when the owner wants a network-enabled worker. There is no persisted setting to enable networking while retaining the filesystem sandbox.
This adds an optional
networkAccessboolean to thecodexentry insubagents.providers. It defaults to false, is passed through the daemon and driver into Codex turn sandbox policies, and applies to both new and continued agents. Read-only and full-access policies remain unchanged; other providers reject the setting. The configuration reference and generated JSON schema include the option and daemon restart guidance.Verified with typecheck, the full test suite (111 passed, 1 skipped), the configuration round-trip test, build, and package-install smoke test. Regression coverage checks omitted/false/true values and new/resumed turns across the existing sandbox modes. An isolated run through the built DevSpace CLI also loaded
networkAccess: truefrom JSONC, launched a real Codex subagent, and completed an HTTPS request with HTTP 200; its session recorded workspace-write with network access enabled. No MCP-host UI acceptance was repeated for this change.Summary by CodeRabbit
