About

Inspect and explain conversations in the local Deep Agents Code SQLite session store. Use to look up the current thread's title or name, as a fallback when LangSmith trace tooling is unavailable, for offline or untraced sessions, or when asked to identify or summarize a local dcode thread, inspect checkpoint metadata, list recent local threads, or parse $DEEPAGENTS_HOME/.state/sessions.db and a thread UUID or prefix.

Use cases: monitoring-observability, debugging

# Deep Agents Thread Inspector

For conversation inspection, prefer LangSmith tooling when available for a traced thread. For saved thread titles, use the local store. Use `scripts/inspect_sessions.py` instead of manually decoding database blobs. It opens the database read-only and deserializes the root message channel with LangGraph's strict MsgPack loader — reading the materialized messages from the latest checkpoint, or replaying writes in checkpoint order when that fast path is unavailable — and emits JSON.

## Look up the current thread's title

Call `get_current_thread_id` to identify this conversation, then run the script with that ID and `--mode summary` as shown below. Read `thread.thread_name`: it contains the saved title, including manual renames, with a fallback to the latest root checkpoint's name for older stores. If it is `null`, report that the thread has no saved title. If the current ID is unavailable, ask for it; do not infer the current thread from the most recent entry in the thread list.

## Inspect local state

Resolve `SKILL_DIR` to the directory containing this `SKILL.md`; do not assume a user, project, or installation-specific location. Start with the smallest useful view:

```bash
python3 "$SKILL_DIR/scripts/inspect_sessions.py" THREAD_ID --mode latest-turn
```

A unique thread-ID prefix is accepted. Select another view when needed:

```bash
python3 "$SKILL_DIR/scripts/inspect_sessions.py" THREAD_ID --mode summary
python3 "$SKILL_DIR/scripts/inspect_sessions.py" THREAD_ID --mode transcript
```

Use `--include-metadata` only when run, repository, model, checkpoint, or LangGraph metadata matters. Use `--max-content N` to raise or lower the default 4,000-character limit per message, tool result, or tool-call argument.

If the user does not know the ID, list recent threads first:

```bash
python3 "$SKILL_DIR/scripts/inspect_sessions.py" --list 20
```

Pass `--db PATH` only for a non-default session store. The default is `$DEEPAGENTS_HOME/.state/sessions.db`, or `~/.deepagents/.state/sessions.db` when that variable is unset. `DEEPAGENTS_SESSIONS_DB` overrides both. The script applies the same rules dcode does, so a relative or `~user` value is rejected rather than resolved to a database dcode never writes.

## Explain the result

Synthesize the JSON rather than pasting it verbatim.

- State the user's request, the assistant's conclusion, and significant tool actions or failures.
- Distinguish stored facts from your interpretation.
- For the latest turn, describe only the final user message and subsequent activity unless earlier context is required to make it understandable.
- Mention truncation when a relevant record has `content_truncated` or `args_truncated` set.
- Surface reconstruction problems when the result includes a top-level `warnings` array (for example, a corrupt checkpoint, a skipped write, or malformed metadata) so conclusions are appropriately hedged.
- Do not expose unrelated credentials, tokens, personal data, or hidden reasoning that may appear in local records.

## Safety

Keep inspection read-only. Do not deserialize an untrusted database: checkpoint deserialization is intended for trusted local Deep Agents state. Do not mutate or delete session rows unless the user separately and explicitly requests it.
