# Deep Agents Thread Inspector If LangSmith tooling is available for a traced thread, prefer it. Otherwise, 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. ## 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.
