# Feature 15: Session Creation Richness
|
|
|
|
**Implementation approach:** Check existing extensions — most already implemented
|
|
|
|
## Summary
|
|
|
|
v1 `CreateSessionRequest` had `mcp` (full MCP server config with OAuth, env headers, bearer tokens), `skills` (sources with git refs), `agent_version`, `directory`. v2 needs to support these at session creation time.
|
|
|
|
## Current v2 State — MOSTLY IMPLEMENTED
|
|
|
|
Investigation shows that **most of these are already supported** via `_meta.sandboxagent.dev` passthrough in `session/new`:
|
|
|
|
| Field | v1 | v2 Status | v2 Mechanism |
|
|
|-------|-----|-----------|-------------|
|
|
| `directory` | `CreateSessionRequest.directory` | **Implemented** | `cwd` parameter extracted from payload |
|
|
| `agent_version` | `CreateSessionRequest.agent_version` | **Implemented** | `_meta.sandboxagent.dev.agentVersionRequested` (stored, forwarded) |
|
|
| `skills` | `CreateSessionRequest.skills` | **Implemented** | `_meta.sandboxagent.dev.skills` (stored, forwarded) |
|
|
| `mcp` | `CreateSessionRequest.mcp` | **Stored but not processed** | `_meta.sandboxagent.dev.mcp` passthrough — stored in `sandbox_meta` but no active MCP server config processing |
|
|
| `title` | (session metadata) | **Implemented** | `_meta.sandboxagent.dev.title` extracted to `MetaSession.title` |
|
|
| `requestedSessionId` | (session alias) | **Implemented** | `_meta.sandboxagent.dev.requestedSessionId` |
|
|
| `model` | `CreateSessionRequest.model` | **Implemented** | `_meta.sandboxagent.dev.model` via `session_model_hint()` |
|
|
| `variant` | `CreateSessionRequest.variant` | **Deferred** | Out of scope in current implementation pass |
|
|
|
|
### Confirmation from `rfds-vs-extensions.md`
|
|
|
|
- Skills: "Already extension via `_meta[\"sandboxagent.dev\"].skills` and optional `_sandboxagent/session/set_metadata`"
|
|
- Agent version: "Already extension via `_meta[\"sandboxagent.dev\"].agentVersionRequested`"
|
|
- Requested session ID: "Already extension via `_meta[\"sandboxagent.dev\"].requestedSessionId`"
|
|
|
|
## v1 Types (for reference)
|
|
|
|
```rust
|
|
#[derive(Debug, Deserialize, JsonSchema, ToSchema)]
|
|
pub struct CreateSessionRequest {
|
|
pub agent: String,
|
|
pub message: String,
|
|
pub directory: Option<String>,
|
|
pub variant: Option<String>,
|
|
pub agent_version: Option<String>,
|
|
pub mcp: Option<Vec<McpServerConfig>>,
|
|
pub skills: Option<Vec<SkillSource>>,
|
|
pub attachments: Option<Vec<MessageAttachment>>,
|
|
}
|
|
|
|
#[derive(Debug, Clone, Deserialize, Serialize, JsonSchema, ToSchema)]
|
|
pub struct McpServerConfig {
|
|
pub name: String,
|
|
pub command: String,
|
|
pub args: Option<Vec<String>>,
|

|
|
pub struct SkillSource {
|
|
pub name: String,
|
|
pub source: SkillSourceType,
|
|
}
|
|
|
|
#[derive(Debug, Clone, Deserialize, Serialize, JsonSchema, ToSchema)]
|
|
#[serde(tag = "type", rename_all = "snake_case")]
|
|
pub enum SkillSourceType {
|
|
Git { url: String, ref_spec: Option<String> },
|
|
Local { path: String },
|
|
}
|
|
```
|
|
|
|
## What Remains
|
|
|
|
### MCP Server Config Processing
|
|
|
|
The `mcp` field is stored in `sandbox_meta` but **not actively processed**. To fully support MCP server configuration at session creation:
|
|
|
|
1. Extract `_meta.sandboxagent.dev.mcp` array from `session/new` params
|
|
2. Forward MCP server configs to the agent process (agent-specific: Claude uses `--mcp-config`, Codex/OpenCode have different mechanisms)
|
|
3. This is complex and agent-specific — may be deferred
|
|
|
|
### Recommendation
|
|
|
|
Since most fields are already implemented via `_meta` passthrough:
|
|
- **No new work needed** for `directory`, `agent_version`, `skills`, `title`, `requestedSessionId`, `model`
|
|
- **MCP config processing** is the only gap — evaluate whether the agent processes already handle MCP config from `_meta` or if explicit processing is needed
|
|
- Mark this feature as **largely complete** with MCP as a follow-up
|
|
|
|
## Files to Modify (if MCP processing is needed)
|
|
|
|
| File | Change |
|
|
|------|--------|
|
|
| `server/packages/sandbox-agent/src/acp_runtime/mod.rs` | Extract and process `mcp` config from `_meta.sandboxagent.dev.mcp` during session creation |
|
|
| `server/packages/agent-management/src/agents.rs` | Accept MCP config in agent spawn parameters |
|
|
|
|
## Docs to Update
|
|
|
|
| Doc | Change |
|
|
|-----|--------|
|
|
| `docs/sdks/typescript.mdx` | Document all supported `_meta.sandboxagent.dev` fields for session creation |
|
