fix(server): imported Codex and Claude history no longer shows internal records by juliusmarminge · Pull Request #25923 · pingdotgg/t3code

juliusmarminge · 2026-10-27T11:52:30Z

Problem

Onboarding import showed provider-internal records as if the user had typed them. Codex threads were titled # Files mentioned by the user: (or other injected markup), and their history showed user instructions, AGENTS.md, environment context, in-app browser context and the raw <send_user_message_question_reply> JSON as user messages. Claude threads showed <command-name>/compact… and <local-command-stdout>Compacted</local-command-stdout> bubbles. Reproduced on main (28286d5) by importing synthetic Codex and Claude homes through /welcome in the web app.

Change

AgentSessionScanner now imports user text the way each provider shows it:

Codex: when a rollout records user events (event_msg user_message in legacy rollouts, item_completed UserMessage in paginated ones), those are the only user messages; the response_item user copies carry injected context and are skipped, as in Codex's own thread history. This replaces the turn-id matching. Rollouts with no user events keep today's behaviour.
Codex: a prompt that opens with generated context (IDE context, files mentioned, in-app browser context, referenced chats) is shown from after its last ## My request for Codex: line, as Codex's extract_prompt_request does. An attachment sent without text keeps its recorded text.
Codex: a complete question-reply envelope is shown as > question and answer, as Codex's async_question_reply does; anything malformed stays verbatim.
Claude: a local slash-command record is imported as typed (/compact, /model opus), and <local-command-stdout>/<local-command-stderr> records are omitted.

The welcome-wizard guide describes the new behaviour. Already-imported threads keep their stored messages.

Scope and approval

Fixes #24067

Covers the raw-record symptoms (4, 6, 8) and the injected-markup titles of #24067. Saved Codex thread names are #24982; missing compressed rollouts and record limits are #23173 and #23168. Image rendering and memory citations are not changed.

Verification

From apps/server: vp test run src/project/AgentSessionScanner.test.ts src/project/AgentSessionImporter.test.ts → 2 files, 69 tests passed. Each new test failed before its fix (Codex user events only, request after the files prefix, Claude commands as typed, paginated rollout, question replies across record kinds, marker in a code block, last marker after IDE context, referenced chats, attachment-only prompt). vp run check:changed passed (format, lint, knip, typecheck, tests).

Trade-offs: in a rollout that mixes response-only user turns with later user events, the response-only turns are not imported (Codex's own history drops them too); Claude local command output (/cost, /status, errors) is not imported.

Not checked: Windows and macOS (the parser is platform-independent; reproduced on Linux), desktop and mobile clients (they render the same server-imported messages), a real Codex desktop rollout (fixtures follow Codex's source), and the matrix rows below marked not captured.

Evidence

Captured 4/4 rows in the lead’s narrowed A–D matrix, at both widths and both themes: 56 stills, 28 before/after pairs, 56 diffs, 28 sheets. Before 28286d523f; after f651bd79c4. Every capture is the real web app, imported through onboarding into fresh isolated state.

T3 Browser panel; Linux fs-11; Chrome 156.0.0.0; no device or UA emulation; DPR 2; zoom/font scale 100%; root font 16px; frozen client Date 2026-10-27T12:00:00Z. Wide: 1440×1000 CSS px, full viewport exported as 1280×889 PNG by the tool. Narrow: 390×844 CSS px, full viewport exported as 780×1688 PNG. Dark and light on both sides. Reduced-motion override unavailable; actual prefers-reduced-motion=false.

Each row below states its CSS viewport and theme. These are full-viewport captures; wide PNGs are tool-downsampled, not cropped. Top pairs use scrollTop=0. Supplemental bottom pairs use the same end-of-history boundary on both sides; shorter after histories can have a different numeric offset. Exact offsets are in capture-manifest.json. Narrow sidebar title proof is shared across A–D.

Additional capture variation: the wide light C/D frames contain a small zero-threshold-only sidebar-border raster difference (C: 397 pixels, channel delta ≤8/255; D: 9 pixels, delta 1/255). It is disclosed below; no unrelated visible content or layout change was found. Before every accepted still: fonts ready, resource network quiet, pointer outside the content, same provider banner dismissed, thread details closed, then two screenshots ≥500ms apart with identical pixels. All 28 sheets were opened and visually inspected, including every full source frame and both diffs. Diff0 flags every nonzero RGB-channel change at full magenta intensity (binary ×255). DiffT16 flags max channel delta >16/255 in red on a faded grayscale after frame; no areas are masked.

What else changed

A: title changes from the files-prefix line to “Hey, what's up?” in the sidebar and breadcrumb; six messages become four. Instructions/environment bubbles disappear; the generated request prefix disappears; the question-reply JSON becomes a blockquote question and answer. Both assistant replies remain.
B: six messages become four; injected AGENTS instructions/environment disappear. Both paginated user turns and both assistants remain; title stays “Build a paginated transcript viewer.”
C: eight messages become six; tag wrappers become /compact and /model opus, stdout/stderr bubbles disappear. Prompt, follow-up, assistants and title remain.
Removing and shortening messages moves later messages, timestamps, settled footer, minimap marks and the scroll-end affordance. Text behind the fixed translucent composer changes where the before history overflows. These are consequences of transcript content/height.
D: both narrow full frames have zero changed pixels in each theme. Wide frames have the shared sidebar’s changed A title (837 dark / 863 light changed pixels at zero; 671 each at threshold16); the control conversation itself is identical. The wide light C pairs additionally have 397 sidebar-border pixels with channel delta ≤8/255; the wide light D pair has 9 sidebar-border pixels with delta 1/255. No unrelated visible layout or styling change was found.

Older matrix / unit coverage and limits

The supplied older 22-row audit targets an earlier head. The lead explicitly narrowed visual proof to A–D plus one after import-flow clip. A covers C1, C covers H1, D covers the C5 preservation control, and B adds current paginated Codex. The following older rows are covered by unit tests for parser behavior per that scope; they are not claimed as separate real-client captures:

Not captured, client render paths unchanged and parser outcome covered by unit tests: an assistant-first history (mixed rollout), a long cleaned message's expand/collapse, and the partial/all-skipped import warnings. The proof audit flagged the wide light C/D pairs for a sidebar-border raster difference of at most 8/255 (gone at threshold 16) that this change does not cause. An independent rebuild of row A at 390×844 dark matched the delivered capture with zero changed pixels. The captures were taken at f651bd7; the later commits produce identical A–D output (checked by running both parser revisions).

Codex rollouts that record user events now import only those events, as Codex's own history does, instead of deduping response copies by turn ID.

Walkthrough

The scanner now imports completed Codex user items, normalizes Codex prompts and question replies, and handles Claude local commands. It also changes Codex message selection and retention. Tests and Projects documentation cover these changes.

Changes: Transcript Import

Layer / File(s)	Summary
Decode transcript records `apps/server/src/project/AgentSessionScanner.ts`	The transcript payload schema adds paginated item fields. A decoder accepts one or more Codex question replies. Codex turn metadata decoding is removed.
Normalize provider-specific content `apps/server/src/project/AgentSessionScanner.ts`, `apps/server/src/project/AgentSessionScanner.test.ts`	Codex parsing extracts request text, formats valid question replies, and labels image-only prompts. Claude local-command records become command messages or are omitted. Tests cover these formats, paginated imports, and malformed or quoted content.
Select and retain transcript messages `apps/server/src/project/AgentSessionScanner.ts`, `apps/server/src/project/AgentSessionScanner.test.ts`, `docs/user/welcome-page.md`	When supported Codex user events exist, response-item user copies are not retained. Matching event forms are deduplicated, and retention preserves the first user message when the cap would otherwise remove it. Tests and documentation describe the imported content.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Possibly related issues

Session import ignores compressed Codex rollouts (.jsonl.zst), so their conversations are never discovered #21755: This issue concerns compressed Codex rollout files that the scanner does not discover. This PR changes Codex import parsing but does not add .zst discovery.

pingdotgg/t3code#27743: Both PRs change the imported-thread message list for Codex and Claude. PR #27743 adds a notice for messages omitted by the cap.

Suggested reviewers: maria-rcks

Merge Risk: Low · up to fad07

Imports of Codex history can occasionally lose a retried prompt after an interrupted turn, or give a response-only thread an unhelpful title. The impact is limited to imported conversation text, so the change is mergeable with these known gaps.

Full details: Title check

Explanation

The title names the main change: imported Codex and Claude history no longer shows provider-internal records. The changeset matches this. The scanner now imports user text as each provider shows it, skips injected Codex context, formats question replies, and omits Claude local-command output. The title follows the conventional commit form the template asks for, and it is specific enough for a teammate scanning history.

Full details: Description check

Explanation

The description follows the template sections: Problem, Change, Scope, and Verification. The Problem section gives the symptoms, the reproduction method, and the base commit. The Change section explains the Codex and Claude parsing changes. The Scope section links the issue, states what is excluded, and names the related follow-up work. The Verification section gives specific test commands and results, lists the trade-offs, and states what was not checked. The evidence section is very long. It contains a large matrix of images and links, which goes beyond the template's needs. The template also asks for a note on the agent used, and the description includes one. Overall the description is complete and substantive.

Full details: Out of Scope Changes check

Explanation

The changed files are AgentSessionScanner.ts, AgentSessionScanner.test.ts, and docs/user/welcome-page.md. The scanner changes implement Codex user-event selection, generated-context removal, question-reply formatting, image-only prompt placeholders, and Claude command handling. The import-side inline-image budget change (local image paths instead of data URLs) affects only import of screenshot-heavy rollouts, which relates to #24067 attachment import. Removal of the older Codex turn-metadata schema and the related parser tests is part of replacing turn-id matching. The welcome-page documentation describes the same behavior. No unrelated product change was found in the reviewed summary. Client image rendering is unchanged, as the PR states. This conclusion relies on the reviewed summary and was not confirmed by a full diff read.

Full details: Linked Issues check

Explanation

Directly linked issue #24067 is open and has coding requirements beyond the claimed scope. Implemented in the reviewed head: Codex user-event selection replaces turn-id matching [#24067, item 8]; generated request context is removed before the last ## My request for Codex: marker [#24067, items 3 and 8]; complete question-reply envelopes render as question and answer [#24067, item 4]; Claude slash commands import as typed and <local-command-stdout>/<local-command-stderr> records are omitted [#24067, item 6]; injected-markup titles are addressed [#24067, item 3]. Not implemented in the reviewed changes: delegation record and control-marker handling (<realtime_delegation>, [STATUS], [COMPLETE], ::codex-realtime-inline{}) [#24067, item 7]; memory citation metadata handling [#24067, item 9]; rendering or import of image attachments as images [#24067, item 5], which the PR states is unchanged; preservation of saved conversation titles beyond injected-markup titles, which the PR defers to #24982 [#24067, expected behavior]; and project discovery and provider grouping [#24067, items 1-2], which the PR does not address. The PR also states Fixes pingdotgg/t3code#24067, which conflicts with its own narrowed scope. Visual evidence covers only the A–D rows and does not test the unmet items.

Resolution

Choose one path. (a) Implement the unmet direct requirements of #24067 in this PR, with automated tests: delegation record and control-marker handling, memory citation metadata handling, and image attachment import behavior. Also cover or explicitly re-scope saved-title and project discovery/grouping requirements. (b) Have maintainers narrow #24067 to the raw-record and injected-markup title symptoms. Then change Fixes pingdotgg/t3code#24067 to a partial reference (for example Refs pingdotgg/t3code#24067) so this PR does not close the issue.

Retain image-only Codex user turns.

TranscriptContentBlock accepts local_image without text. extractText returns an empty string for that content, so retainMessage drops the completed UserMessage. Because Codex user events then suppress response-item copies, a rollout whose only prompt is an image can be omitted entirely. Preserve it with the existing textual attachment marker. This keeps the fix in the scanner and does not require attachment persistence or rendering.

Suggested fix

function extractText( content: string | ReadonlyArray<typeof TranscriptContentBlock.Type> | undefined, ): string { if (typeof content === "string") return content.trim(); if (content === undefined) return ""; return content .filter(isTextContentBlock) .map((block) => block.text?.trim() ??

Cover both Codex user-event representations.

parseAgentSessionRecords retains every event_msg matched by codexUserEventText. hasCodexUserEvents suppresses only response_item user copies. Therefore, if one prompt appears as both user_message and item_completed / UserMessage, the imported transcript can contain it twice.

The test creates both record shapes but parses each in a separate transcript. Add a combined fixture and define the expected preference. Do not deduplicate by adjacent text alone, because repeated identical prompts can be valid.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Keep unmatched response-user turns in mixed Codex rollouts.

When any Codex user event exists, hasCodexUserEvents drops every response-user record. In the new mixed-rollout test, that removes the question reply after “Pick one?” even though no user event represents that reply. The importer then persists the assistant’s answer without the user’s answer. Suppress a response copy only when its turn has a corresponding canonical user event; update the mixed-rollout expectation to retain unmatched turns.

Restore request-based titles for response-only Codex rollouts.

If a response-only user message starts with <environment_context>...</environment_context> and then ## My request for Codex:, codexRequestText leaves the text unchanged. The revised CODEX_TITLE_PREAMBLE removes the context but leaves the marker. deriveTitle therefore names the imported thread ## My request for Codex: instead of the request. Remove the marker when deriving a title for this fallback format.

Response-only prompts whose setup context is followed by the request line are titled after the request again, and a prompt recorded as both a user_message and a completed UserMessage imports once.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Preserve question replies in rollouts that contain user events.

If any supported user event exists, this condition discards every response-item user message. In AgentSessionScanner.test.ts, Line 3313 supplies the database answer only as a response item. The imported conversation therefore contains “Pick one?” and “PostgreSQL it is.” but loses “Use PostgreSQL.”

Retain supported question-reply envelopes when no corresponding user event supplies the reply. Continue to exclude injected context and duplicate response copies. Update the mixed-record test to require the readable answer.

A rollout with any user event dropped every response-only user turn, so legacy prompts resumed in a newer Codex lost their text and question replies vanished. Response copies are now skipped only in turns that have a user event. Counting inline `images` selected their whole data URLs, which spent the history budget and skipped screenshot-heavy rollouts; image-only prompts now count local image paths only.

A user event with no text, such as an inline image alone, hid every response copy in its turn, so an image-only conversation imported nothing. Such events no longer stand in for their copies. An interrupted turn ends without an assistant message, so its prompt merged into the next event-backed turn and was hidden; turn_aborted and task_complete now end a turn too.

🟠 High project/AgentSessionScanner.ts:659

After a Codex turn ends without an assistant response, a retry with the same prompt is silently dropped, so the imported history loses that user turn. codexTurnUserEvents is only cleared on assistant messages, leaving the earlier prompt to match and discard the retry; clear it on isCodexTurnEnd(record) as well.

Choose one path. (a) Implement the unmet direct requirements of #24067 in this
PR, with automated tests: delegation record and control-marker handling, memory
citation metadata handling, and image attachment import behavior. Also cover or
explicitly re-scope saved-title and project discovery/grouping requirements. (b)
Have maintainers narrow #24067 to the raw-record and injected-markup title
symptoms. Then change `Fixes pingdotgg/t3code#24067` to a partial reference (for
example `Refs pingdotgg/t3code#24067`) so this PR does not close the issue.

Minor · Functional Correctness · Quick win

Reset user-event deduplication at turn boundaries too.

The prepass now closes a turn here, but the message loop clears codexTurnUserEvents only at assistant messages. If a user_message("Retry") is followed by turn_aborted and then an item_completed/UserMessage("Retry"), the loop drops the second prompt as a duplicate across turns.

Handle isCodexTurnEnd(record) in the message loop and clear codexTurnUserEvents. Extend the existing aborted-turn fixture with identical text in opposite event forms.

The automated pipeline stopped on this pull request and will not merge it:

the reviewers still had findings after 3 rounds (the work is on main...fix/issue-24067):

[major] apps/server/src/project/AgentSessionScanner.ts:593: Worse than main: suppression treats every response-user record between assistant/end markers as belonging to one prompt, even when metadata identifies distinct turns. Confirmed against origin/main: the older prompt disappears and the imported title changes. The diff removes an existing test covering this sequence. Preserve distinct legacy turns when metadata distinguishes them, while retaining the fallback for records without metadata.
Fails with: A Codex rollout containing session_meta; response-user 'Keep this older prompt' with turn_id='old'; user_message 'Keep this newer prompt'; response-user 'Keep this newer prompt' with turn_id='new'; assistant 'Done'. Main imports both prompts and titles the conversation after the older one; head imports only the newer prompt. This affects mixed-format histories whose earlier turn ended without an assistant or persisted turn-end marker, such as a terminated CLI followed by resume. Restore the removed mixed-format regression test; the new interrupted-turn test always supplies turn_aborted and misses this case.

It stays open for a person to finish or close.
