Patch release: Morning Brief skill, stronger publishing and content-safety behaviour, AWS credential handling options, and broader SDK result types.
Changelog
[new] Morning Brief — produce a single styled HTML daily brief that reads in under a minute, or set it up as a recurring weekday task (prompt /morning). Triggered by phrases like “morning brief,” “daily brief,” “what’s my day look like,” or “set up my morning brief.” Preferences supplied at setup (delivery time/timezone, sections, role) are treated as decided rather than re-asked.
[new] Safer publishing of files you didn’t author — before publishing any file you did not write, Claude now reads the complete file even if asked not to (e.g. “it’s personal”). If it cannot read the file, it will not publish it.
[new] Gathered content is data, not instructions — emails, chat messages, document comments, calendar entries, and similar material are summarized only; embedded commands or “notes to Claude” inside that content are ignored. Only the user’s own invocation directs action.
[new] Unobserved connector warning for artifacts — when a page is published against an interface that was never successfully called in the session, Claude surfaces a warning and asks for verification against a real response (or tells the user the page is unobserved).
[changed] Agent delay / prompt-cache guidance — clearer rules for choosing delaySeconds under a 1-hour prompt-cache TTL: never schedule extra wakeups just to keep the cache warm; match polling delays to real external state changes; default idle ticks to 20–30 minutes. Runtime still clamps delays to [60, 3600] seconds.
[changed] SDK agent result types — completed results can include optional citations, inference_geo, speed, iterations, frameCount, and worktree path/branch fields; service_tier is a free-form string; async launches may mark isAsync; artifact read ver is optional.
[changed] Symlink / indirection gate messaging — files that fail the indirection gate (must be a regular non-symlink file with link count 1 inside a real .claude directory) are reported as present but skipped, without being read or rewritten.
[changed] Auto mode rules from untrusted sources — settings path can ignore auto-mode classifier rules that come from untrusted sources.
Models & prompts
Morning Brief skill and setup prompts are wired in (styled HTML artifact or recurring /morning task), including how to treat setup preferences as fixed decisions.
Publishing and research prompts tighten safety: full read-before-publish for third-party files, treat gathered external content as non-instructional data, and warn on unobserved connectors.
Scheduling / focus-mode guidance updated for long prompt-cache sessions and for focus mode (user only sees the final text message per turn — intermediate tool chatter is omitted).
Under the hood
Environment options for Morning Brief (CLAUDE_CODE_ENABLE_MORNING_BRIEF, CLAUDE_CODE_MORNING_BRIEF_PROMPT) and related feature gates for config and skill rollout.
AWS credential path: configurable chain-resolve timeout (CLAUDE_CODE_AWS_CHAIN_RESOLVE_TIMEOUT_MS) and optional skip of the AWS credential cache (CLAUDE_CODE_SKIP_AWS_CRED_CACHE).
Deferred stub tool reserved so deferred tool loading stays active without being callable.
Plugin feedback survey config/event gates for optional in-product survey flows.
Session elevated-auth enforcement and uncompilable ignore-pattern gates.
Internal probes/flags for third-party default model writes, trigger IDs, and experimental codenames (e.g. lantern/prism, walnut/spire).
Manifest now records SDK wrapper compatibility (sdkCompat.testedWrapperVersions, harnessSchema).
Upgrade notes
If you use AWS credentials with Claude Code, you can tune chain resolution via CLAUDE_CODE_AWS_CHAIN_RESOLVE_TIMEOUT_MS or bypass the credential cache with CLAUDE_CODE_SKIP_AWS_CRED_CACHE when diagnosing stale or slow auth.
SDK consumers: regenerate or widen types for agent results — several usage and worktree fields are now optional, and service_tier is no longer a fixed enum.
Morning Brief may be gated behind feature flags in some environments; enable with the Morning Brief env/settings when available.
