- 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
- Add Claude Fable 5 and Claude Mythos 5 to the model tables with pricing,
context window, and model-selection guidance
- Document Fable-specific API behavior: always-on adaptive thinking (explicit
disabled returns 400), protected-thinking display and replay rules, new
tokenizer (~30% more tokens), refusal stop reason with server-side fallbacks
and SDK fallback middleware, 30-day data-retention requirement
- Add the full Migrating to Claude Fable 5 guide section and checklist,
including the Mythos Preview migration path
- Refresh skill trigger description, effort/compaction/task-budget notes,
caching minimums, structured-output and dynamic-filtering support tables
The model field on agent create accepts {id, speed}, not
{type: "model_config", id, speed}. Aligns with the shape documented
elsewhere in managed-agents-core.md and the request body table.
Add shared/managed-agents-memory.md covering the Memory Stores public
beta under managed-agents-2026-04-01: object model (memstore_/mem_/
memver_), create + seed, attach via resources[] at session-create time,
FUSE mount at /mnt/memory/<store>/, host-side CRUD with create-by-path
vs update-by-id, content_sha256 preconditions, and versions/redact.
Wire it through all cross-references: SKILL.md beta-headers namespace
and reading guide; api-reference SDK method rows, delete/archive quirks
bullet, AddResource note, and three new endpoint sections; core.md
architecture diagram and resources[] enumerations; environments.md
Resources intro; overview.md beta-headers table, Reading Guide row, and
archive-is-permanent bullet.
