Conversation
…rsisted A Claude thread records its native session id before the CLI confirms the session. Stopping the first turn while the CLI is still starting (or a CLI killed before it persisted the prompt) leaves an id with no transcript, and every later turn resumed it and failed with "No conversation found with session ID". The V1 adapter had a grace period for this (pingdotgg#13999); V2 did not. ClaudeAdapterV2.resumeThread now checks the CLI's session storage through the SDK (getSessionMessages) when the native session has no live query, and fails when there is no conversation. The turn start then takes its existing fresh-session fallback: a new native id with a full-thread-summary handoff. A transcript that holds no user or assistant message counts as absent, which is what the CLI's own resume reports for it. Fixes pingdotgg#15854 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This PR makes a focused Claude adapter bug fix, adding a persisted-session check while preserving live-query and valid-resume behavior. The recovery uses the existing fresh-session fallback, and the new behavior is covered by targeted tests without schema, deployment, or configuration changes. You can add or adjust custom eligibility rules. Learn more. |

Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~15 minutes Change: Bug fix · Severity of issue fixed: Medium Suggested reviewers: Merge Risk: 🟡 Moderate · up to For Claude providers using a separate storage directory, a valid conversation may be replaced by a fresh native session. Align the lookup with the configured store before merging. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change targets a bounded session-recovery problem and retains existing runtime permission controls. However, the new lookup does not receive the provider’s configured session-store environment, so it may incorrectly replace a valid session. No privilege expansion or transcript disclosure was demonstrated, and some recovery behavior remains unverified. Retained concerns

- Line 848: Update sessionHasMessages in ClaudeAdapterV2 to perform its resume
lookup against the configured Claude store used by the query, including any
provider-level CLAUDE_CONFIG_DIR override, rather than relying on the server
process environment. Keep the SDK’s dir option reserved for the project
directory.

@anthropic-ai/claude-agent-sdk 0.3.276 getSessionMessages implementation getSessionMessages dir CLAUDE_CONFIG_DIR environment github npm source
💡 Result:
For **`@anthropic-ai/claude-agent-sdk@0.3.276`**, the changelog confirms that version, but doesn’t publish the function’s implementation. It records `0.3.276` as a parity update; the nearby `0.3.275` entry describes fixes to `getSessionMessages()`, including missing assistant messages and queued user messages. ([github.com](https://github.com/anthropics/claude-agent-sdk-typescript/blob/main/CHANGELOG.md?utm_source=openai))
**What the available sources establish:**
- `getSessionMessages(sessionId, { dir, limit, offset })` reads the session’s JSONL transcript; `dir` is the project directory, and omitting it searches across projects. ([github.com](https://github.com/xiaolai/anthropic-docs/blob/main/skills/claude-agent-sdk/SKILL-typescript.md?utm_source=openai))
- A secondary description of the storage layout says transcripts are under `~/.claude/projects/<sanitized-cwd>/<session-id>.jsonl`, respecting `CLAUDE_CONFIG_DIR`. That’s useful for locating files, but it is **not** the SDK’s version-pinned implementation source. ([github.com](https://github.com/nshkrdotcom/claude_agent_sdk/blob/main/guides/sessions.md?utm_source=openai))
**What remains unresolved:** I couldn’t verify from a version-pinned `0.3.276` source file exactly how `getSessionMessages` reads `CLAUDE_CONFIG_DIR`—for example, whether it reads `process.env` directly or delegates path resolution to another helper. The current GitHub changelog and third-party docs are not proof of that implementation detail for `0.3.276`.

Use the configured Claude store for the resume lookup.
getSessionMessages(input.sessionId, { limit: 1 }) runs in the server process and resolves CLAUDE_CONFIG_DIR from process.env. It does not receive the query's env option. A provider instance can override CLAUDE_CONFIG_DIR, and the query passes that override to the Claude SDK child process. If the transcript exists only in that configured store, this lookup returns no messages. ProviderTurnStartService then treats the resume as failed, drops the native reference, and starts a fresh native session.
Make sessionHasMessages read the same configured session store as the query before rejecting the resume. Do not pass CLAUDE_CONFIG_DIR as dir; the SDK defines dir as a project directory, not a config directory.

at line 848:
Update sessionHasMessages in ClaudeAdapterV2 to perform its resume lookup
against the configured Claude store used by the query, including any
provider-level CLAUDE_CONFIG_DIR override, rather than relying on the server
process environment. Keep the SDK’s dir option reserved for the project
directory.

What Changed
ClaudeAdapterV2.resumeThreadnow checks whether the CLI actually holds a conversation for the thread's native session id before the turn start resumes it. When the native session has no live query, the adapter asks the SDK (getSessionMessages(id, { limit: 1 })); if there is none,resumeThreadfails withProviderAdapterResumeThreadError, andProviderTurnStartServicetakes its existing fresh-session fallback (new native id,full_thread_summaryhandoff). A live query is skipped: it is the CLI process, and its transcript is empty between CLI startup and the first persisted prompt.The lookup is a new
sessionHasMessagesmethod onClaudeAgentSdkQueryRunner, next to the existingsubagentLaunchToolUseIdthat reads the same storage. The replay testkit answers it withtruewithout consuming a frame, so recorded transcripts are unchanged.Why
Fixes #15854 (V2 recurrence of #2336, which #13999 fixed in the V1 adapter that #2829 later removed).
A Claude thread records its native id as a
strongref before the CLI confirms the session. Pressing Stop within the first couple of seconds of a new thread (beforesystem/init) makes the V2 adapterinterrupt+closeback to back, so the CLI never writes a transcript. The next turn counts the interrupted attempt as a native turn (nativeThreadHasTurns), opens withresume, and the CLI answersNo conversation found with session ID. That repeats on every later turn; the thread can only be fixed by editingstatev2.sqlite.The check is reactive rather than keyed on a persisted "confirmed" flag because the CLI has a window where neither option works — see below.
Verification
How the problem was established. From the per-thread provider log and
statev2.sqliteof an affected thread (details in #15854):query.open { sessionId }→command_lifecycle: queued→ user Stop 2.4 s later →query.interrupt/query.close1 ms apart → next turnquery.open { resume }→result error_during_execution, num_turns: 0, errors: ["No conversation found…"]. Nosystem/initwas ever received and no transcript exists under~/.claude/projects/.Why a transcript check, and why "no messages" rather than "no file". I killed
claude -p --session-id <id> --input-format stream-jsonat each stage and then tried both ways of reopening the id (Claude Code 2.1.287):--resume <id>--session-id <id>system/initai-titlerow onlystream_eventIn the middle row the id is dead both ways, so the only recovery is a fresh id — which is what the turn start's fallback does.
getSessionMessagesreports[]for both of the first two rows and a message for the third, matching--resumeexactly:--resumealso finds a transcript recorded under a different cwd, so the lookup passes nodir.Tests. Three cases added to
ClaudeAdapterV2.test.ts(ClaudeAdapterV2 resume): no conversation →ProviderAdapterResumeThreadErrorwith the lookup recorded; conversation present → resumes; live query → storage not consulted. With the adapter change stashed, the first two fail (Effect.flipon a successful resume; aresumeThreadthat ignores the runner). The fallback that the failure feeds into is already covered byProviderTurnStartService.test.ts.Not checked. I did not run the fix inside a packaged desktop build against the originally stuck thread; the end-to-end path after
resumeThreadfails (fallback →ensureThread→sessionIdopen) is the existing one exercised byProviderTurnStartService.test.tsand #15770's identity tests.Checklist
