hotfix(backend/copilot): refactor transcript to SDK-based atomic full-context model - #12318
Conversation
…-context model Major refactor to eliminate CLI transcript race conditions and simplify code: **Core Changes:** - Build transcript from SDK messages during streaming (TranscriptBuilder) - Atomic full-context model: each upload REPLACES previous transcript entirely - Eliminated CLI file reading race conditions and merge complexity - Removed ~200 lines of transcript merge/synthetic detection code - Use orjson via backend.util.json with fallback for 2-3x faster JSON ops **Key Improvements:** - No more race conditions between CLI writes and SDK reads - Simpler, more reliable transcript handling - Added fallback parameter to json.loads() for cleaner error handling - Fixed garbage collection bug in background task handling - Fixed double upload bug in timeout handling - Moved SDK imports to top-level per code style - Downgraded PII-risk logging from WARNING to DEBUG - Added 30s timeout to prevent session lock hang **Files Changed:** - backend/copilot/sdk/transcript_builder.py (NEW): SDK message → JSONL builder - backend/copilot/sdk/transcript.py: Simplified upload/download - backend/copilot/sdk/service.py: Use TranscriptBuilder, remove stop hook - backend/copilot/sdk/security_hooks.py: Remove on_stop parameter - backend/util/json.py: Add fallback support for graceful error handling - backend/copilot/sdk/transcript_test.py: Updated tests (24/24 passing) **Testing:** - All transcript tests passing (24/24) - Verified with real session logs showing proper transcript growth - Verified with Langfuse traces showing proper turn tracking (1-8) Closes race condition issues and simplifies maintenance going forward.

In `@autogpt_platform/backend/backend/copilot/sdk/service.py`:
- Around line 1212-1219: The transcript builder only records AssistantMessage
right now; extend the SDK message handling loop to also persist the
user/tool-result half of turns by detecting ToolResultBlock and user message
types, calling _format_sdk_content_blocks(sdk_msg.content) and then appending
the formatted blocks to the transcript_builder with the appropriate API (e.g.,
transcript_builder.add_user_message or
transcript_builder.add_tool_result_message—use the builder method that matches
the message type). Ensure the same serialization used for AssistantMessage (via
_format_sdk_content_blocks) is applied so session.messages entries added after
tool execution are also represented in the uploaded transcript.
- Around line 1567-1579: The background upload_task can outlive the session lock
and later overwrite a newer transcript; wrap or replace the scheduled
upload_task (the one added to _background_tasks on TimeoutError) so it never
writes directly to the deterministic session transcript path after being
backgrounded—either await it before releasing the session lock or change the
upload coroutine to write to a temporary/unique path and perform an atomic
rename only if the session id/turn still matches the current session state at
rename time; update the code handling upload_task, _background_tasks, and the
finally block that releases the session lock so the backgrounded task cannot
clobber newer transcripts.
In `@autogpt_platform/backend/backend/copilot/sdk/transcript_builder.py`:
- Around line 59-62: The warning in transcript_builder.py currently logs
transcript content via logger.warning("Failed to parse transcript line: %s",
line[:100]) which can leak user/assistant text; change the warning to a
content-free message like logger.warning("Failed to parse transcript line") and
move any non-sensitive preview to a DEBUG log (e.g., logger.debug) using a
hashed or truncated preview of the line (use a stable hash such as
hashlib.sha256(line.encode()).hexdigest() or a short safe preview) so parsing
failures are visible without exposing raw transcript content; update the code
around the json.loads(line, fallback=None) handling and replace the existing
warning call accordingly.
- Around line 64-67: load_previous() currently discards any entries whose
data["type"] is not "user" or "assistant", which drops non-strippable nodes
(e.g., "system") that strip_progress_entries() preserves and leads to dangling
parentUuid/resume problems; update load_previous() in transcript_builder.py to
reuse the same preservation logic as strip_progress_entries() (or call
strip_progress_entries() first) so that entries marked non-strippable (such as
"system" or other preserved types) are kept instead of filtered out, ensuring
parentUuid links remain valid when reconstructing transcripts.
In `@autogpt_platform/backend/backend/copilot/sdk/transcript.py`:
- Around line 223-230: The loop in transcript validation uses json.loads(...,
fallback=None) but doesn't verify the parsed value is a mapping before calling
entry.get(), causing AttributeError on JSON scalars; update the loop in the
function that contains the shown block to explicitly check that entry is an
instance of dict (or has mapping behavior) after json.loads and return False if
not, then only call entry.get("type") when that shape check passes; apply the
same shape guard in strip_progress_entries() before using .get() so non-object
JSON lines (e.g., strings, numbers, arrays) are treated as invalid and produce a
clean False/skip rather than raising.

Backend/frontend OpenAPI codegen convention: In backend/api/features/store/model.py, the StoreSubmission and StoreSubmissionAdminView models define submitted_at: datetime | None, changes_summary: str | None, and instructions: str | None with no default. This is intentional to produce “required but nullable” fields in OpenAPI (properties appear in required[] and use anyOf [type, null]). This matches Prisma’s submittedAt DateTime? and changesSummary String?. Do not flag this as a required/nullable mismatch.

Learning: Keep the pre-commit hook pattern broad for autogpt_platform/backend to ensure OpenAPI schema changes are captured. Do not narrow to backend/api/ alone, since the generated schema depends on Pydantic models across multiple directories (backend/data/, backend/blocks/, backend/copilot/, backend/integrations/, backend/util/). Narrowing could miss schema changes and cause frontend type desynchronization.

Learning: In the AutoGPT Copilot backend, ensure that SVG images are not treated as vision image types by excluding 'image/svg+xml' from INLINEABLE_MIME_TYPES and MULTIMODAL_TYPES in tool_adapter.py; the Claude API supports PNG, JPEG, GIF, and WebP for vision. SVGs (XML text) should be handled via the text path instead, not the vision path.

125-147: LGTM! Clean removal of Stop hook support aligns with the SDK-based transcript refactor.The function signature correctly removes the
on_stopparameter, and the docstring updates reflect the new approach where transcript handling is managed atomically via the SDK rather than through stop-hook callbacks. Security hooks remain intact:
- Task concurrency limiting with
task_tool_use_ids- Workspace path validation
- User isolation enforcement
- Dangerous pattern blocking
The
on_compactcallback is appropriately retained for context compaction observability.
310-317: Hooks configuration correctly excludes Stop hook.The hooks dictionary now contains only the four necessary event types (
PreToolUse,PostToolUse,PostToolUseFailure,PreCompact), consistent with the removal of stop-hook based transcript capture in favor of the newTranscriptBuilderapproach mentioned in the PR objectives.

PR #12318 — hotfix(backend/copilot): refactor transcript to SDK-based atomic full-context model
Author: majdyz | Reviewer: automated-squad (8 specialists) | Files: 6 (+534/-382, net -200)
🎯 Verdict: APPROVE_WITH_CONDITIONS
What This PR Does
Eliminates CLI transcript race conditions by replacing the file-reading approach with an in-memory TranscriptBuilder that builds transcripts from SDK messages during streaming. Each upload atomically REPLACES the full previous transcript — no more merge logic, no more incomplete writes. Also migrates to orjson, fixes a GC bug in background tasks, fixes a double-upload bug, and adds a 30s upload timeout with background continuation.
Specialist Findings
🛡️ Security ✅ — No blocking issues. Path sanitization intact, auth scoping preserved. Removing read_transcript_file() and stop hook reduces attack surface. PII in DEBUG-level log (acceptable). orjson fallback sentinel pattern is correct.
🏗️ Architecture load_previous() drops summary entries produced by SDK compaction — could lose compacted context on resume. Also: _format_sdk_content_blocks belongs in transcript_builder.py not service.py.
⚡ Performance
🧪 Testing TranscriptBuilder (140 new lines, core class) has zero unit tests. _format_sdk_content_blocks (46 new lines) has zero tests. json.loads fallback parameter (43 lines changed) has zero tests. Existing validate_transcript and strip_progress_entries tests are well-covered. Author reports 24/24 tests passing but coverage gaps are significant for new core code.
📖 Quality ✅ — Clean, well-structured. Excellent structured logging ([SDK][session][Turn]). Good dead code removal. Minor: stale module docstring in transcript.py, _format_sdk_content_blocks placement.
📦 Product ✅ — High positive user impact. Fixes real race conditions causing incomplete transcripts. Breaking changes are internal-only (all callers updated). PII logging downgrade (WARNING→DEBUG) is appropriate.
📬 Discussion json.py only). CodeRabbit posted 5 new findings at 13:10 UTC (unaddressed): (1) tool-result messages not captured in builder, (2) timeout upload race could re-introduce overwrite, (3) PII in WARNING log, (4) load_previous drops non-user/assistant entries, (5) non-object JSON lines cause AttributeError. CI tests (3.11/3.12/3.13) were still pending at review time.
🔎 QA ✅ — Full end-to-end pass. Multi-turn copilot with tool use works correctly. Atomic transcript model confirmed in backend logs: Turn 1 uploaded 5 entries (4264B), Turn 2 downloaded 5, appended, uploaded 18 entries (10498B). Chat history persists across page navigation. No console errors. 7 screenshots captured.
Conditions (Must Address Before/Shortly After Merge)
-
Add unit tests for
TranscriptBuilder— 140 lines of new core code with zero tests. At minimum:load_previousround-trip,add_user_message/add_assistant_messagechaining,to_jsonloutput format, edge cases (empty content, malformed JSON, missing uuid). -
Verify
summaryentry handling inload_previous()— Currently filters to onlyuser/assistanttypes (transcript_builder.py:67). If SDK compaction producessummaryentries, they'll be silently dropped on resume, potentially losing compacted context. Either add"summary"to accepted types or document why it's safe to drop. -
Address CodeRabbit finding: non-object JSON lines —
json.loadswithfallback=Nonesucceeds for JSON arrays/scalars, then.get()raisesAttributeError. Addisinstance(data, dict)guard in bothload_previous()andstrip_progress_entries().
Should Fix (Follow-up OK)
_format_sdk_content_blocksplacement — Move fromservice.pytotranscript_builder.pywhere it belongs (transcript concern, not service concern)- Add unit tests for
_format_sdk_content_blocks— 46-line function handling 4 SDK block types + unknown, zero tests - Add tests for
json.loadsfallback parameter — New feature used throughout transcript code, zero tests - Update stale docstring in
transcript.py— Still references "when the SDK's Stop hook fires we read this file" - Add error-logging callback for background upload tasks — Currently failures are silently swallowed after timeout
- Investigate CodeRabbit timeout-race finding — After 30s timeout, background upload continues while session lock is released. Verify whether a new turn could start and produce a newer upload that gets overwritten by the stale background task
- Triple-parse optimization — Previous entries are parsed 3× (load→Pydantic serialize→strip). Store raw JSONL lines for unchanged entries
- Skip
strip_progress_entriesfor builder-generated transcripts — SDK-built transcripts never contain progress entries
QA Evidence
| Step | Screenshot |
|---|---|
| Landing page | landing |
| Copilot home | copilot-home |
| Turn 1 response | response |
| Turn 2 tool calls | followup |
| Turn 2 complete | done |
| Chat history reload | history |
Risk Assessment
Merge risk: LOW-MEDIUM | Rollback: EASY (revert one commit, old transcript code was self-contained)
The atomic model is architecturally correct and the hotfix solves a real, active bug (incomplete transcripts from race conditions). QA confirms end-to-end functionality works. The conditions above are important but none block the immediate hotfix value — the current race condition in production is worse than any of these edge cases.
@ntindle @Swiftyos @Pwuts — Hotfix looks good overall. Core transcript race condition is fixed, QA confirms multi-turn copilot works end-to-end with atomic uploads. Main gap is test coverage for the new TranscriptBuilder class (140 lines, 0 tests) — recommend adding tests before or immediately after merge. Also verify the summary entry handling if SDK compaction is in use.

Learning: Keep the pre-commit hook pattern broad for autogpt_platform/backend to ensure OpenAPI schema changes are captured. Do not narrow to backend/api/ alone, since the generated schema depends on Pydantic models across multiple directories (backend/data/, backend/blocks/, backend/copilot/, backend/integrations/, backend/util/). Narrowing could miss schema changes and cause frontend type desynchronization.

Learning: In the AutoGPT Copilot backend, ensure that SVG images are not treated as vision image types by excluding 'image/svg+xml' from INLINEABLE_MIME_TYPES and MULTIMODAL_TYPES in tool_adapter.py; the Claude API supports PNG, JPEG, GIF, and WebP for vision. SVGs (XML text) should be handled via the text path instead, not the vision path.

Learning: In Python files under autogpt_platform/backend (recursively), rely on poetry run format to perform formatting (Black + isort) and linting (ruff). Do not run poetry run lint as a separate step after poetry run format, since format already includes linting checks.

ResultMessage represents session completion status (success/error), not tool execution results. Adding it to the transcript corrupts conversation history during --resume by injecting error messages as user messages. Fixes CodeRabbit discussion r2895784911

When
_build_query_message()compressessession.messages[transcript_msg_count:-1]intoquery_message, the builder still records onlycurrent_messagehere. Line 1572 then storesmessage_count=len(session.messages)anyway, so a successful replace can permanently drop the gap while marking the transcript as fully current. Rehydrate the missing turns intotranscript_builderfirst, or keep the stored watermark at the last transcript-covered message.Also applies to: 1138-1141, 1544-1574
1119-1136:⚠️ Potential issue | 🟠 MajorUse the raw user text in the multimodal transcript branch.
The text block at Line 1123 is still built from
query_message, so any<conversation_history>wrapper or attachment hint gets persisted as if the user authored it. The plain-text path already avoids this at Lines 1138-1141; the image path should build transcript blocks fromcurrent_messageplus the actual image blocks instead.🤖 Prompt for AI Agents

## Summary - Fixes tool results not being captured in the CoPilot transcript during SDK-based streaming - Adds `transcript_builder.add_user_message()` call with `tool_result` content block when a `StreamToolOutputAvailable` event is received - Ensures transcript accurately reflects the full conversation including tool outputs, which is critical for Langfuse tracing and debugging ## Context After the transcript refactor in #12318, tool call results from the SDK streaming loop were not being recorded in the transcript. This meant Langfuse traces were missing tool outputs, making it hard to debug agent behavior. ## Test plan - [ ] Verify CoPilot conversation with tool calls captures tool results in Langfuse traces - [ ] Verify transcript includes tool_result content blocks after tool execution
…-context model (#12318) Major refactor to eliminate CLI transcript race conditions and simplify the codebase by building transcripts directly from SDK messages instead of reading CLI files. The previous approach had race conditions: - SDK reads CLI transcript file during stop hook - CLI may not have finished writing → incomplete transcript - Complex merge logic to detect and fix incomplete writes - ~200 lines of synthetic entry detection and merge code **Atomic Full-Context Transcript Model:** - Build transcript from SDK messages during streaming (`TranscriptBuilder`) - Each upload REPLACES the previous transcript entirely (atomic) - No CLI file reading → no race conditions - Eliminates all merge complexity - **NEW**: `transcript_builder.py` - Build JSONL from SDK messages during streaming - **SIMPLIFIED**: `transcript.py` - Removed merge logic, simplified upload/download - **SIMPLIFIED**: `service.py` - Use TranscriptBuilder, removed stop hook callback - **CLEANED**: `security_hooks.py` - Removed `on_stop` parameter - **orjson migration**: Use `backend.util.json` (2-3x faster than stdlib) - Added `fallback` parameter to `json.loads()` for cleaner error handling - Moved SDK imports to top-level per code style guidelines - Fixed garbage collection bug in background task handling - Fixed double upload bug in timeout handling - Downgraded PII-risk logging from WARNING to DEBUG - Added 30s timeout to prevent session lock hang - `merge_with_previous_transcript()` - No longer needed - `read_transcript_file()` - No longer needed - `CapturedTranscript` dataclass - No longer needed - `_on_stop()` callback - No longer needed - Synthetic entry detection logic - No longer needed - Manual append/merge logic in finally block - No longer needed - ✅ All transcript tests passing (24/24) - ✅ Verified with real session logs showing proper transcript growth - ✅ Verified with Langfuse traces showing proper turn tracking (1-8) From session logs: - **Turn 1**: 2 entries (initial) - **Turn 2**: 5 entries (+3), 2257B uploaded - **Turn N**: ~2N entries (linear growth) Each upload is the **complete atomic state** - always REPLACES, never incremental. ``` backend/copilot/sdk/transcript_builder.py (NEW) | +140 lines backend/copilot/sdk/transcript.py | -198, +125 lines backend/copilot/sdk/service.py | -214, +160 lines backend/copilot/sdk/security_hooks.py | -33, +10 lines backend/copilot/sdk/transcript_test.py | -85, +36 lines backend/util/json.py | +45 lines ``` **Net result**: -200 lines, more reliable, faster JSON operations.
