Update claude-api skill: scheduled deployments, vault env-var credentials, system.message events (#1297)

Browse Source 
- Add Managed Agents scheduled deployments: new
  shared/managed-agents-scheduled-deployments.md (cron schedules, deployment
  runs, pause/auto-pause), Deployments and Deployment Runs API reference,
  beta-header coverage, and SKILL.md routing
- Vault environment_variable credentials: secrets substituted at egress with
  networking allowlists; secrets guidance in tools, client-patterns, and
  onboarding docs rewritten around them; self-hosted sandbox caveats noted
- Add system.message event for mid-session system prompt updates (Opus 4.8
  only) to the events guide and API reference

**Which beta header goes where:** The SDK sets `managed-agents-2026-04-01` automatically on `client.beta.{agents,environments,sessions,vaults,memory_stores}.*` calls, and `files-api-2025-04-14` / `skills-2025-10-02` automatically on `client.beta.files.*` / `client.beta.skills.*` calls. You do NOT need to add the Skills or Files beta header when calling Managed Agents endpoints. **Exception — session-scoped file listing:** `client.beta.files.list({scope_id: session.id})` is a Files endpoint that takes a Managed Agents parameter, so it needs **both** headers. Pass `betas: ["managed-agents-2026-04-01"]` explicitly on that call (the SDK adds the Files header; you add the Managed Agents one). See `shared/managed-agents-environments.md` → Session outputs.

## Common Pitfalls
- **Agent FIRST, then session — NO EXCEPTIONS** — the session's `agent` field accepts **only** a string ID or `{type: "agent", id, version}`. `model`, `system`, `tools`, `mcp_servers`, `skills` are **top-level fields on `POST /v1/agents`**, never on `sessions.create()`. If the user hasn't created an agent, that is step zero of every example.
- **Agent ONCE, not every run** — `agents.create()` is a setup step. Store the returned `agent_id` and reuse it; don't call `agents.create()` at the top of your hot path. If the agent's config needs to change, `POST /v1/agents/{id}` — each update creates a new version, and sessions can pin to a specific version for reproducibility.
- **MCP auth goes through vaults** — the agent's `mcp_servers` array declares `{type, name, url}` only (no auth). Credentials live in vaults (`client.beta.vaults.credentials.create`) and attach to sessions via `vault_ids`. Anthropic auto-refreshes OAuth tokens using the stored refresh token.
- **MCP auth goes through vaults** — the agent's `mcp_servers` array declares `{type, name, url}` only (no auth). Credentials live in vaults (`client.beta.vaults.credentials.create`) and attach to sessions via `vault_ids`. Anthropic auto-refreshes OAuth tokens using the stored refresh token. Vaults also hold `environment_variable` credentials for non-MCP services (CLIs, SDKs, direct API calls) — substituted at egress, never visible in the sandbox.
- **Reconcile resources before the first run** — a session with a clear ask but a missing tool, credential, data mount, or context will discover the gap mid-run, then flail and give up. Before creating the session, check that every action in the task maps to a configured tool/MCP server, every MCP server has a vault credential, and every referenced file/host is mounted/reachable. When helping a user set one up, run the reconciliation in `shared/managed-agents-onboarding.md` → §3 Pre-flight viability check.
- **Stream to get events** — `GET /v1/sessions/{id}/events/stream` is the primary way to receive agent output in real-time.
- **SSE stream has no replay — reconnect with consolidation** — if the stream drops while a `agent.tool_use`, `agent.mcp_tool_use`, or `agent.custom_tool_use` is pending resolution (`user.tool_confirmation` for the first two, `user.custom_tool_result` for the last one), the session deadlocks (client disconnects → session idles → reconnect happens → no client resolution happens). On every (re)connect: open stream with `GET /v1/sessions/{id}/events/stream` , fetch `GET /v1/sessions/{id}/events`, dedupe by event ID, then proceed. See `shared/managed-agents-events.md` → Reconnecting after a dropped stream.
