chore(deps): bump @anthropic-ai/claude-agent-sdk to ^0.3.302

[edspencer]

Closes #471

Bumps @anthropic-ai/claude-agent-sdk in packages/core from ^0.3.283 to ^0.3.302 (current npm latest) and refreshes pnpm-lock.yaml. packages/core/package.json is the only manifest referencing the SDK.

Retargeted 2026-10-17. This PR originally targeted ^0.3.286. Upstream moved on while it was open, so it now targets 0.3.302. The branch name still says 0.3.286 — harmless, and renaming it would close this PR. Issue #471 has been updated to match.

The lockfile diff is scoped entirely to the SDK and its eight platform binaries. Peer ranges are unchanged: @anthropic-ai/sdk >=0.93.0, @modelcontextprotocol/sdk ^1.29.0, zod ^4.0.0.

Breaking changes reviewed — none require adaptation

Two permissionMode default changes (0.3.286, and 0.3.302 for third-party providers / telemetry-off / fresh installs): when permissionMode is omitted, Claude Code now picks the starting mode itself. Neither reaches herdctl, which never omits it:

• toSDKOptions — packages/core/src/runner/sdk-adapter.ts:181 — always sets result.permissionMode = agent.permission_mode ?? DEFAULT_PERMISSION_MODE ("acceptEdits").
• The CLI runtime — packages/core/src/runner/runtime/cli-runtime.ts:241-242 — always passes --permission-mode.

So an agent configured permission_mode: default still gets exactly default, and one with no permission_mode still gets acceptEdits.

0.3.300 — thinking: { type: 'disabled' } and maxThinkingTokens: 0 now run as adaptive thinking on models that can't disable thinking. Inert here: herdctl never sets either option (see the result.* assignments in sdk-adapter.ts — permissionMode, allowedTools, disallowedTools, systemPrompt, settingSources, mcpServers, plugins, model, maxTurns, resume, forkSession, tools, cwd, env, and the MCP transport fields; no thinking config).

0.3.300 — updatedInput from PreToolUse and PermissionRequest hooks is now validated and unknown keys dropped. Inert here: packages/core/src/session/session-hooks.ts:126-127 registers only Stop and PostToolUse callbacks.

0.3.295 — the SDK now sends named option values as --flag=value. This is internal to the SDK's own spawn of Claude Code. herdctl's CLI runtime builds its own argv and is unaffected.

0.3.299 — reserved MCP server names refused (__proto__, __defineGetter__, …). herdctl does not generate server names from untrusted input in that shape.

One runtime behaviour change to be aware of

0.3.302 makes fork subagents (subagent_type: "fork") on by default in SDK sessions, matching the terminal; CLAUDE_CODE_FORK_SUBAGENT=0 opts out. This is a behaviour change for agents that spawn subagents, not a compile break, and nothing in herdctl needs to change for it. Note this is unrelated to herdctl's own forkSession option, which is session forking.

API surface: additive

Diffing sdk.d.ts, agentSdkTypes.d.ts, sdk-tools.d.ts, core.d.ts and bridge.d.ts from 0.3.286 → 0.3.302:

• Added: BUILTIN_TOOL_NAMES, LEGACY_TOOL_NAME_ALIASES (0.3.301).
• Removed or renamed: none.
• PermissionMode, SdkPluginConfig and SettingSource are byte-identical, so packages/core/src/runner/__tests__/sdk-type-contract.test.ts is unaffected.

Other additions we don't yet consume: per-tool permission_policy on sdk-type MCP configs, addPlugins on reloadPlugins(), claude_code_version on initialize, autoCompactWindow on AgentDefinition, overageEnabled on SDKRateLimitInfo, agent_id / parent_task_id / run_id on subagent and task events, nextFireAt on Cron tool output, and offset on WebFetch input.

Fixes inherited

importSessionToStore skipping transcript rows containing U+2028/U+2029 on Node 24 and Bun; assistant text blocks losing citations in streamed responses; includePartialMessages streams never emitting message_stop on a cut or interrupted stream; a tool call to an in-process MCP server left hanging after toggleMcpServer()/setMcpServers(); commands_changed arriving before init or twice at startup; setModel() failing while at a usage limit; in-process SDK MCP servers named constructor/toString dropped on SpareProcess.claim(); the sandbox option discarding an inline settings.sandbox block; plus the earlier 0.3.284–0.3.286 fixes to foreground subagent task-tracking tools, SDK MCP schema conversion, forkSession() history reading and getSessionMessages().

Verification

Gate	Result
pnpm build	✅ 7/7 packages
pnpm typecheck	✅ 11/11 tasks
pnpm lint	✅ 6/6 tasks (11 warnings / 12 infos, all pre-existing — no .ts changed)
pnpm test (local)	✅ chat 11, slack 16, cli 9, discord 17, web 10 files all pass; core 115/116 files — 1 pre-existing environmental failure below
CI (run 39054880725)	✅ all green — Unit Tests, Typecheck, Build + Smoke Tests, Web UI Tests, Lint & Format, GitGuardian

CI Unit Tests: green, and it settles the earlier failure

Unit Tests passes on this commit: core is 116/116 files, with src/scheduler/__tests__/scheduler.test.ts at 51/51 ✓ and src/state/__tests__/directory.test.ts at 41/41 ✓.

That retroactively confirms the diagnosis on the previous (0.3.286) push, where Unit Tests failed twice on scheduler.test.ts. Those were known open flake #452 (frozen Date.now racing a real setTimeout on the shared self-hosted runner), not the dependency bump:

• No scheduler code changed between the two commits — the retarget touches only package.json, pnpm-lock.yaml and the changeset — yet the same file is now green.
• The failing subset had moved between the two earlier attempts of one identical commit (4 tests, then a different 4), which is load variance rather than regression.
• The SDK is absent from that test's module graph: scheduler.test.ts imports ../scheduler.js, and scheduler.ts never imports ./schedule-runner.js — the only file in packages/core/src/scheduler/ that reaches ../runner/index.js and thence the SDK.

Because #452 is intermittent, this green run should be read as "not caused by the bump", not as "#452 is fixed".

The one local failure (environmental, passes in CI)

src/state/__tests__/directory.test.ts > initStateDirectory > throws StateDirectoryCreateError when parent directory is not writable:

• The dev box used here runs as uid 0. The test chmods a directory to 0444 and expects mkdir to fail, but root bypasses directory permissions — so the test's premise cannot hold.
• It fails identically with the pre-bump package.json restored, and it touches no SDK code.
• It passed in CI on the previous push (41/41 ✓), which runs as non-root — confirming the diagnosis.

No UI surface is touched by this change, so there is no visual evidence to attach.

Explanation

The PR updates packages/core/package.json from ^0.3.283 to ^0.3.286 and adds .changeset/bump-claude-agent-sdk-0-3-286.md for @herdctl/core. The reported pnpm build, pnpm typecheck, and pnpm test results satisfy the verification objective, including the identified pre-existing environment-dependent failure. The summary does not provide reviewable evidence for the required pnpm-lock.yaml refresh. pnpm-lock.yaml is intentionally excluded from review, so this requirement cannot be established. The reported explicit permissionMode handling supports the issue's no-adaptation requirement.

Scope the SDK type claim to herdctl’s APIs.

SDK v0.3.285 added Settings.allowedProviders and startup_failure_reason: "provider_not_allowed". These APIs are not used or re-exported by herdctl. Keep the no-adaptation conclusion, but remove the broad claim that no exported SDK types changed.

Suggested changeset wording

-No exported SDK types changed, so no code adaptation was needed.
+Although v0.3.285 added `Settings.allowedProviders` and `startup_failure_reason: "provider_not_allowed"`, herdctl does not use or re-export these APIs, so no code adaptation was needed.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change

0.3.286 is breaking upstream in one respect — the TypeScript Agent SDK no longer sends a default `permissionMode`, letting Claude Code apply the settings' `permissions.defaultMode` instead — but herdctl is unaffected: `toSDKOptions` always sets `permissionMode` explicitly (`agent.permission_mode ?? "acceptEdits"`), and the CLI runtime always passes `--permission-mode`. No exported SDK types changed, so no code adaptation was needed.
