- CWD: `/Users/pascal/Code/business/convx`

## User

complete .gitignore with some light python defaults

## Agent

Updated `.gitignore` with common Python entries:

- `__pycache__/` – bytecode cache
- `*.py[cod]` – compiled Python files
- `*.egg-info/` – package metadata
- `dist/`, `build/` – build artifacts
- `.env` – local env vars and secrets

## User

OK let's change the terms. 

- convx sync => checks if currently in a git repo. Syncs all conversations that took place in this repo and its subfolders into the repo
- convx backup => does the full backup.

Can you change the terms and docs etc

## Agent

Let me also look at the CLI source code.

## Agent

Now I have the full picture. Here's the plan:
- `convx sync` → replaces `sync-repo`, auto-detects the current git repo (no `--repo-path` needed, uses CWD)
- `convx backup` → replaces `sync`, the full backup to a target repo
- `sync-repo` goes away

Let me update the CLI and both docs.

## Agent

Now update the README:

## Agent

Now update the developer documentation:

## Agent

Done. Here's a summary of what changed:

**`cli.py`**
- `sync` now auto-detects the CWD as the git repo, filters and writes conversations for that repo only — no `--output-path` or `--repo-path` needed.
- `backup` is the new name for the old `sync` — full export to a specified `--output-path`.
- `sync-repo` is removed.

**`README.md`** — updated all command examples and descriptions to match.

**`documentation.md`** — added a Commands section up top and updated the repo-scoped sync explanation.

## User

Okay, so if we do a sync for a specific repository, then of course the folder structure shouldn't contain the entire relative path of the user to the home directory, but it should be top level the user, next level the tool, next level concrete sessions

## Agent

Let me look at how the path mapping is done in the engine.

## Agent

The fix touches `_build_output_dir` in the engine (add a flat mode) and the `sync_command` in the CLI to pass it through.

## Agent

Now pass `flat_output=True` from the `sync` command in the CLI:

## Agent

Now update the docs to reflect the flat structure for `sync`:

## Agent

Now update the example output section to show both cases:

## Agent

Finally update `documentation.md` to reflect the flat path for sync:

## Agent

Done. Here's what changed:

**`engine.py`** — `_build_output_dir` now accepts a `flat` flag; when `True` it produces `history/<user>/<source-system>/` with no machine name or path nesting. `sync_sessions` takes a matching `flat_output` param.

**`cli.py`** — `sync_command` passes `flat_output=True`; `backup_command` leaves it at the default `False`.

**`README.md` / `documentation.md`** — updated path structure descriptions and example outputs to show the difference between the two commands.

## User

Okay, so now all we need to do is yeah, yeah. make sure that the output markdown that is being spit out. Okay, a couple of things. So one is currently the the JSON I think when you when it says developer it should actually be the system prompt, right?

Because that's the system prompt. let's do the following. Anytime it's either a tool use or it's a system prompt, let's wrap that in markdown inside of a HTML. comment block because I actually I want to be able to read that markdown kind of like a conversation which is a turn by turn between the user and the agent.

And so ideally that's almost resembles the typical conversation flow that one can have in like ChatGPT and Gemini and Claude and whatnot. and the system prompt at the beginning is a bit confusing because it always takes a lot of space. but one actually wants to be able to read immediately okay what the what did did what did the user say and what did the agent reply.

So let's put into code blocks all of the system prompt bits. and then looking at one concrete example that we've already exported the first two messages are currently stating role developer then two role user but these are actually agent files in environment context then two more role developer and then finally the actual user message so can you also check whether codecs the codecs files that we extract data from if they give better hints at what is actually coming from the user and what is system prompt, etcetera. 

relevant files: @history/pascal/codex/.2026-02-15-1642-agents.md-instructions-for--users-pascal-code-business-convx.json  and@symlinks/codex/sessions/2026/02/15/rollout-2026-02-15T17-42-31-019c622e-a9f9-7d62-a898-31059da7705e.jsonl

## Agent

Let me read both files to understand the structure.

## Agent

Now let me look at the raw JSONL source to understand what Codex provides:

## Agent

Now let me read the codex adapter and render code:

## Agent

Now let me look at the models:

## Agent

Now I have a complete picture. Here's what the Codex JSONL reveals that the current adapter misses:

1. `role: "developer"` = system/infrastructure (permissions, app context, collaboration mode) — should be `system`
2. `role: "user"` with `# AGENTS.md` or `<environment_context>` = injected context — also `system`
3. Actual user input is confirmed by `event_msg` entries with `type: "user_message"` — use those as the ground truth
4. `function_call` / `function_call_output` types = tool use — also need wrapping
5. `reasoning` entries have a human-readable `summary` field

The plan: add a `kind` field to `NormalizedMessage` (`user`, `assistant`, `system`, `tool`), update the Codex adapter to classify correctly, and update the renderer to wrap `system`/`tool` in HTML comments.

## Agent

Now rewrite the Codex adapter:

## Agent

Now update the renderer:

## Agent

Now let's run the existing tests to make sure nothing is broken:

## Agent

The test predates our CLI rename. Let me look at it and fix it:

## Agent

The tests need updating for the CLI rename and flat structure. Let me rewrite them:

## Agent

All passing. Let me also do a quick smoke test by running the actual sync on this repo and checking the output:

## Agent

The session is skipped because the index fingerprint hasn't changed. Let me force re-export by clearing the index entry:

## Agent

The output still shows the old format — let me check the actual current file:

## Agent

The new render code works correctly — the HTML comments are there. Let me verify the file was actually written correctly:

## Agent

The new file has the correct slug (derived from the real first user message). Let me peek at it:

## Agent

Let me jump ahead to where the actual conversation starts:

## Agent

Everything is working correctly. Here's a summary of what changed:

**`models.py`** — Added `kind: str = "user"` field to `NormalizedMessage`. Values: `"user"`, `"assistant"`, `"system"`, `"tool"`.

**`adapters/codex.py`** — Full rewrite of parsing logic:
- `session_meta.base_instructions` → extracted as the first `system` message (the actual Codex personality/instructions prompt)
- `role: "developer"` → `kind: "system"` (permissions, app-context, collaboration_mode)
- `role: "user"` → cross-referenced against `event_msg` type `user_message` entries (the ground-truth for what the human actually typed); matching → `kind: "user"`, non-matching (AGENTS.md injections, `<environment_context>`) → `kind: "system"`
- `function_call` / `function_call_output` → `kind: "tool"` with structured text
- `reasoning` → `kind: "system"` using the summary text

**`render.py`** — `system` and `tool` messages are wrapped in `<!-- ... -->` HTML comments (invisible when rendered, preserved in raw file). `user` shows as `## User`, `assistant` as `## Agent`. `first_user_text` now only looks at `kind == "user"` so the filename slug is derived from the actual human message.

**Side effect:** the exported filename changed from `agents.md-instructions-for-...` (old — slugified from the injected AGENTS.md context) to `can-you-check--history-codex-...` (new — slugified from the real first user message).

## User

OK now make a plan for how to do the same that we have for codex but for claude history sessions. I symlinked the claude config in symlinks/claude for your convenience. 

Their file structure looks a bit more complex though. can you see if you can reproduce the hierarchy there to determine which files belong to "the current git repo"?

## Agent

Let me explore the Claude file structure to understand what we're working with.

## User

I think the sessions-index.json is super valuable

## Agent

There it is — it's inside each project directory, not at the top level. Let me read it.

## User

check symlinks/claude/projects/-Users-pascal-Code-everycure-orchard/sessions-index.json

## Agent

This is perfect. The `sessions-index.json` gives us everything we need without even opening the JSONL files. Here's what each entry contains and how it maps to our needs:

**Fields available:**
- `sessionId` — UUID matching the `.jsonl` filename
- `fullPath` — direct path to the session file
- `projectPath` — the actual decoded filesystem path (e.g. `/Users/pascal/Code/everycure/orchard`)
- `summary` — Claude's own human-readable title for the session
- `firstPrompt` — first user message (truncated, useful for filename slug)
- `created` / `modified` — ISO timestamps
- `gitBranch` — what branch was active
- `messageCount` — quick stats
- `isSidechain` — `false` for main sessions, `true` for subagent sessions
- `fileMtime` — for change detection / idempotency

**How this makes the Claude adapter much cleaner than Codex:**

1. **Repo detection is trivial**: the project folder name is just `projectPath` with `/` replaced by `-` (plus a leading `-`). So to find all sessions for `/Users/pascal/Code/business/convx`, you look up folder `-Users-pascal-Code-business-convx`, read its `sessions-index.json`, and you're done — no scanning JSONL files at all.

2. **No `cwd` ambiguity**: `projectPath` in the index is the canonical repo root, not a working directory mid-session. Clean.

3. **Subagents are already flagged**: `isSidechain: false` means top-level conversation. Subagent files are in the `<uuid>/subagents/` subdirectory and would be `isSidechain: true` — easy to skip.

4. **Summary is free**: Claude already generates a `summary` per session. We can use it directly for the filename slug instead of parsing the first user message out of the JSONL.

5. **Idempotency via `fileMtime`**: the index already has modification times, so fingerprinting can use that instead of hashing file content.

**Proposed plan for the Claude adapter:**

```
discover_files(input_path, repo_filter_path):
  - for each project dir under input_path/projects/:
    - decode dir name back to a path (replace leading `-` and `-` → `/`)
    - if repo_filter_path is set and decoded path doesn't start with repo_filter_path: skip
    - read sessions-index.json
    - yield all entries where isSidechain == false

peek_session(entry):
  - return NormalizedSession stub from index fields only (no JSONL read):
    - cwd = entry.projectPath
    - started_at = entry.created
    - title = entry.summary
    - fingerprint = str(entry.fileMtime)

parse_session(entry.fullPath):
  - read the JSONL
  - entry type "user" with role "user" and content type "text" (not "tool_result") → kind="user"
  - entry type "user" with content type "tool_result" → kind="tool"
  - entry type "assistant" with content type "text" → kind="assistant"
  - entry type "assistant" with content type "tool_use" → kind="tool"
  - entry type "assistant" with content type "thinking" → kind="system"
  - entry type "system" → kind="system"
  - skip: queue-operation, file-history-snapshot, summary, progress
```

The JSONL structure is also much simpler than Codex — no ambiguous role assignments, no `developer` vs `user` classification needed. The `type` field on the outer entry cleanly separates what is user input vs tool vs assistant. Would you like me to switch to Agent mode and implement this?

## User

what about all the subfolders of that repo? Maybe users opened an AI session in the subfolders of the repo, we want those too. 

and the subagents conversations would be super valuable to have actually. Would make sense to have a _folder_ per session instead of a markdown file with the root convo at index.md and then the subagents sessions in subfolders

## Agent

Good questions both. Let me check the subagent file structure first.

## Agent

Now I have a complete picture. Here's what I found:

## Agent

The prefix matching strategy works perfectly. Here's the full picture and the updated plan:

---

**Subfolder discovery**

Claude creates one project directory per distinct path the user opened a session in. So `/Users/pascal/Code/everycure/core/apps/home` gets its own project dir `-Users-pascal-Code-everycure-core-apps-home`. Importantly, the encoding is just `path.replace('/', '-')`, so to find all sessions belonging to a repo we don't need to decode — we just match project dirs where the name equals the encoded repo path **or starts with `<encoded-repo>-`**. This correctly captures all subfolders.

Two caveats:
- Subfolder project dirs don't always have a `sessions-index.json` (only populated ones do). Need to fall back to scanning `.jsonl` files directly.
- The encoding is slightly lossy (dashes in path segments look the same as slashes), but in practice this is fine — a false positive means we'd include a session from a sibling repo with a name starting with the same prefix, which is unlikely enough to accept.

---

**Subagents**

The subagent files are at `<project-dir>/<session-uuid>/subagents/agent-<id>.jsonl`. Key observations:
- `sessionId` in subagent entries matches the parent session UUID — so linking parent→subagents is trivial
- `agentId` field identifies the subagent (e.g. `a2636f6`)
- `isSidechain: true` on all entries
- Same message structure as main sessions (user/assistant/tool_use/tool_result entries)
- Not listed in `sessions-index.json` — must be discovered by scanning `<session-uuid>/subagents/` directories

---

**Proposed output structure**

```
history/pascal/claude/
  2026-01-27-preview-deployment-cors-auth-config/   ← folder per session (slug from summary)
    index.md                                         ← main conversation
    agent-a2636f6.md                                 ← subagent by agentId
    agent-a5ac8bd.md
  2026-01-26-pr-preview-deployments-setup/
    index.md
```

This means `NormalizedSession` needs a small tweak — it currently maps 1:1 to one output file, but for Claude we'd want to output a directory. The cleanest approach is probably to keep `NormalizedSession` as-is and introduce a concept of **child sessions** (the subagents), so the engine can render them as sibling files within the same folder.

**One open question**: do you want subagents always included, or only when a session actually has them (i.e. skip creating the folder if there are no subagents, and fall back to a single `.md` file)? Given that subagents are very common in Claude Code, always using the folder structure is probably cleaner for consistency.

## User

yeah do always. Let's plan the full implementation including integration tests please.

## Agent

Let me read the existing code to plan accurately.

## Agent

Now I have everything I need. Let me create the plan.

## User

Implement the plan as specified, it is attached for your reference. Do NOT edit the plan file itself.

To-do's from the plan have already been created. Do not create them again. Mark them as in_progress as you work, starting with the first one. Don't stop until you have completed all the to-dos.

## Agent

Implementing engine changes.

## Agent

Writing child session files as `agent-<id>.md`:

## Agent

Updating discover_files to fall back to `project_dir / f"{sid}.jsonl"` when `fullPath` is missing or the file doesn't exist:

## Agent

Creating tmp_path-based fixtures so project dir names match the encoded repo path:

## Agent

Creating fixtures dynamically so project dir names match the encoded repo path. Adding a test helper and updating the tests:

## Agent

Updating the sync test: the "other" session is excluded at discovery (project dir doesn't match), so `filtered` stays 0.

## Agent

Summary of what was implemented:

## Summary

**Models** ([`models.py`](src/conversation_exporter/models.py))
- Added `summary: str | None = None` and `child_sessions: list["NormalizedSession"] | None = None` to `NormalizedSession`.

**Engine** ([`engine.py`](src/conversation_exporter/engine.py))
- Passes `repo_filter_path` into `adapter.discover_files()`.
- Uses `peek.get("fingerprint")` when available, otherwise `sha256_file()`.
- Uses `session.summary` for the slug in `_session_basename` when present.
- Adds folder-based output when `session.child_sessions is not None`: writes `index.md` and `.index.json` in a session directory, plus `agent-<id>.md` for each child.

**Codex adapter** ([`adapters/codex.py`](src/conversation_exporter/adapters/codex.py))
- Adds `repo_filter_path=None` to `discover_files`.

**Claude adapter** ([`adapters/claude.py`](src/conversation_exporter/adapters/claude.py))
- `discover_files`: scans project dirs, uses `sessions-index.json` when present, filters by encoded repo path prefix.
- `peek_session`: reads from `sessions-index.json` when available, otherwise from the first JSONL line.
- `parse_session`: parses JSONL (user/assistant/system/tool), discovers subagents under `<uuid>/subagents/agent-*.jsonl`, returns `NormalizedSession` with `child_sessions` set.

**Adapters init** ([`adapters/__init__.py`](src/conversation_exporter/adapters/__init__.py))
- Registers `ClaudeAdapter` and `default_input_path("claude") = ~/.claude/projects`.

**Fixtures** (`tests/fixtures/claude_projects/`)
- Static fixtures for manual use.
- Tests use `_setup_claude_fixtures()` to build project dirs that match the encoded repo path.

**Tests** ([`tests/test_integration_claude.py`](tests/test_integration_claude.py))
- `test_claude_backup_writes_session_folders`: backup creates session dirs with `index.md` and `agent-abc1234.md`.
- `test_claude_backup_is_idempotent`: second backup run reports `skipped=4`.
- `test_claude_sync_filters_to_repo_and_subfolders`: sync includes backend and backend-api, excludes other.
- `test_claude_sync_always_uses_folder_structure`: sessions use `slug/index.md` instead of `slug.md`.

All 6 tests pass (4 Claude, 2 Codex).

## User

if I run convx sync I don't see claude sessions

## Agent

Checking the sync command and how it discovers Claude sessions:

## Agent

Adding support to sync multiple sources so `convx sync` can include both Codex and Claude.

## Agent

Adding support for syncing multiple sources so `convx sync` includes both Codex and Claude by default.

## Agent

Sync now defaults to `all` (Codex and Claude). Updating the README to document this:

## Agent

Made two changes:

1. **Default sync sources** – `convx sync` now defaults to `--source-system all`, so it syncs both Codex and Claude. You can still use `--source-system codex` or `--source-system claude` for a single source.

2. **README updates** – The docs now describe the new default and the supported sources.

Running `convx sync` from the convx repo now syncs both Codex and Claude sessions for that repo. Output is under `history/pascal/codex/` and `history/pascal/claude/`.

## User

excellent let's commit your work

## Agent

Commit created. 26 files added in the initial commit, including the convx exporter with Codex and Claude adapters, sync/backup commands, and integration tests.
