Deepagents Code Review
Reviews Deep Agents code for common configuration mistakes and runtime gotchas. It checks for the critical stuff like using interrupt_on without a checkpointer, forgetting the store parameter with StoreBackend, or expecting files to persist across threads with the default StateBackend. Also catches backend misconfiguration, subagent setup errors, and filesystem tool path issues. The anti-confabulation gate is interesting: it forces the reviewer to quote the actual code before flagging anything, which should reduce false positives from LLMs hallucinating problems. Use this when you're working with create_deep_agent, custom backends, or the human-in-the-loop patterns and want a second pair of eyes on the wiring.

Deep Agents Code Review
When reviewing Deep Agents code, check for these categories of issues.
Anti-confabulation (gate 0 — runs before every other gate)
Before issuing any finding — flag a bug, anti-pattern, or improvement — you MUST echo the exact artifact you are judging, quoted from a source you read in this turn:
- The code finding: its
file:lineplus the cited code, read freshly now. - The agent code under review: the
create_deep_agent, backend, subagent, or middleware snippet your finding depends on, quoted from the file you just read.
The artifact is the only source of truth. Never infer what you are reviewing from the branch name, the working directory, surrounding files, or recollection. If your mental model differs from the freshly read source, the source wins. A finding issued without a same-turn echo of its target is invalid — emit the echo first, or do not emit the finding.
This gate exists because an LLM under contextual priming will confidently flag code that is not in the file. It runs before the gates below.
