can you figure out why convx is not pulling in the claude sessions that I've been doing in this folder last few days? mainly it pulls in cursor but hardly any claude from today/yesterday

Let me look at what's actually on disk for the Claude sessions related to this project.

## Agent

_`2026-02-24T19:31:31.086Z`_

Now I can see there's no `sessions-index.json` for this project. Let me check the history output and understand what's been exported.

## Agent

_`2026-02-24T19:32:17.736Z`_

The index was updated at 20:28 today, but sessions from 19:06, 20:07, and 20:12 are missing. Let me run sync with some debug output to see what happens.

## Agent

_`2026-02-24T19:32:25.624Z`_

Discovery works fine. Let me check what the engine does when it encounters these sessions - specifically the fingerprinting/skip logic.

## Agent

_`2026-02-24T19:32:54.554Z`_

Let me run a trace to see exactly what happens during sync for each session.

## Agent

_`2026-02-24T19:33:10.341Z`_

4 sessions are definitely `NEW` and should be processed. But they weren't picked up during the last sync at 20:28. Let me check if parsing them fails.

## Agent

_`2026-02-24T19:33:18.225Z`_

Parsing works. Let me look at the CLI sync command to see how it's invoked, and check the `history_subpath` and `output_repo_path` being used.

## Agent

_`2026-02-24T19:33:31.020Z`_

Found it. The sessions are being filtered by `skip_if_contains`. Let me verify — sessions that involved reading convx source code would contain the literal string `CONVX_NO_SYNC` from the code itself.

## Agent

There's the bug. Every Claude session working on the convx codebase gets filtered out because the sessions contain the literal string `CONVX_NO_SYNC` — which appears in `cli.py` and `engine.py` as the default value of `--skip-if-contains`. Since you're doing AI-assisted development on convx itself, every session that reads those source files ends up with the marker in its content.

The fix is to make the skip marker something that can't accidentally appear in source code — ideally something that requires deliberate action to include. A good option is a special comment format or a dedicated marker that's clearly a user-intent signal, not a code string.

One clean approach: change the marker to something like `CONVX_NO_SYNC_THIS_SESSION` and write it only in a way that's unambiguous (e.g., require it to appear on its own line, or change it to a completely different sentinel). But that still has the same self-referential problem.

A better fix: keep the skip logic but make the `skip_if_contains` check ignore occurrences that came from tool output (i.e., only check user/assistant text messages, not tool results). Or alternatively, change the default skip marker to something that would never appear in normal code, like `CONVX:NOSYNC` or just have users pass `--skip-if-contains` explicitly with no default.

The simplest reliable fix: **remove the default value** and make `skip_if_contains` empty by default, or use a marker that's clearly not a Python string literal, like `<!-- CONVX_NO_SYNC -->`.

## Agent

_`2026-02-24T19:34:15.247Z`_

The fix: `_session_contains` checks all messages including tool results (file contents). When any session reads `cli.py` or `engine.py`, the file content with `CONVX_NO_SYNC` ends up in a tool result message and triggers the filter. 

The right fix is to only check user-typed messages (kind `"user"`) for the skip marker — that's the only place where it makes sense as a deliberate opt-out signal.

## Agent

_`2026-02-24T19:34:19.143Z`_

Now let me verify the fix works and run the tests:

## Agent

_`2026-02-24T19:34:28.214Z`_

`265e1a71` still triggers. Let me see where the marker is appearing in that session.

## Agent

_`2026-02-24T19:34:47.762Z`_

The `265e1a71` session is correctly skipped — it's the Feb 22 session where you literally typed "CONVX_NO_SYNC then :)" as a user message while testing the feature. The fix is working exactly right:

- `265e1a71`: user typed `CONVX_NO_SYNC` → correctly skipped
- `4386297b`: marker only in tool output (file reads) → correctly NOT skipped

Let me run the tests:

## Agent

_`2026-02-24T19:34:53.237Z`_

Let me look at the failing test and its fixture data to understand what needs to change.

## Agent

_`2026-02-24T19:35:25.198Z`_

The test fixture has `"Plan"` in a `kind="system"` message (injected context, not user-typed). The test expected the old "check all messages" behavior. I need to update the fixture to have the skip marker in a genuine `kind="user"` message.

## Agent

_`2026-02-24T19:35:48.068Z`_

The fixture's "Plan" message is `kind="system"` because there's no corresponding `event_msg` entry to mark it as user-typed. I need to add that to the fixture so the message is classified as `kind="user"`.

## Agent

_`2026-02-24T19:35:57.413Z`_

But the test expects `filtered=2` (both sessions filtered). Session 0002 has cwd `/Users/alice/Code/other-project` which won't match the backend repo, so it gets filtered by the cwd filter — not by the skip marker. That's still counted as `filtered`. Let me verify the test should still pass with this logic, and run the tests.

## Agent

_`2026-02-24T19:36:02.018Z`_

All 44 tests pass. Now let's run sync to pick up the missing sessions:

## Agent

_`2026-02-24T19:36:09.822Z`_

4 new sessions exported. The 3 filtered are the 2 peek-errors (empty sessions with no user/assistant messages) plus the one where you deliberately typed `CONVX_NO_SYNC`.

**Root cause:** `_session_contains` was checking all message kinds including `tool` (file read results). Any Claude session that involved reading `cli.py` or `engine.py` — which contain the literal string `"CONVX_NO_SYNC"` as a default argument — would be silently filtered out.

**Fix:** Changed the check to only match `kind="user"` messages (human-typed text), which is the only place the opt-out marker makes sense as a deliberate signal.
