Syncs the claude-api skill with the current upstream source.
## Managed Agents — five new features
- `effort` on the agent's `model` object (a level string or `{"type": "<level>"}`).
It is agent-configuration only: setting it in a per-session `model` override is
silently ignored.
- Optional `version` on agent update, for optimistic concurrency. Omit it for
last-write-wins.
- `initial_events` on session create, collapsing create plus first send into one
call. Validation is all-or-nothing and only `user.message` and
`user.define_outcome` are accepted.
- Environment and memory-store webhooks: four `environment.*` events and three
`memory_store.*` events.
- Event deltas on per-thread streams. Previews are thread-scoped, so a child
thread's previews never reach the session-level stream.
## Corrections to behavior the skill already documented
- Tool output offload triggers at 100,000 characters (~25k tokens), not 100K
tokens, and covers built-in tools rather than MCP alone.
- `system.message` works on four models, checks only the primary model, appends
system context instead of replacing the prompt, and is accepted during a
`requires_action` idle when it trails a tool result in the same request.
- Vault-to-MCP credential matching is normalized (scheme and host lowercased,
default ports and trailing slashes stripped), not byte-exact.
- Multiagent depth greater than 1 is a validation error, not silently ignored.
- Outcome `interrupted` fires even when evaluation never started, and then
carries an empty-string `outcome_evaluation_start_id`.
- Deployment jitter is 15% of the run interval, floor 5s, cap 9 minutes.
- Webhooks retry three times with jittered 5-120s backoff, then drop silently.
Auto-disable is duration-based with three named triggers.
- `session.status_terminated` means completion or error.
- `agent.thinking` is a progress signal and carries no thinking content.
- `processed_at` is already populated on first sighting for
`user.define_outcome`, `user.custom_tool_result`, and `user.tool_result`.
- Session creation does not provision the sandbox.
- Skill `version` applies to Anthropic-authored skills too.
- Console-created vault credentials are header-injection only, and vault
environment-variable substitution skips secrets in URL paths.
- Console trace URLs need the real workspace ID when the API key is not in the
Default workspace.
## Elsewhere in the skill
- Note partner pricing under the first-party price table: Microsoft Foundry
bills at standard API rates, while Amazon Bedrock and Vertex AI are
partner-operated with separate pricing.
- Correct the tool-runner human-in-the-loop guidance, which previously pointed
readers at the manual loop for approval gates the runner's per-turn hooks
already cover.
- Repoint links away from the retired documentation hosts.
- Dedupe eagerly loaded SKILL.md content that the per-section files already
cover.
