# Spec Herdr Review Use this skill to ask one or more external agent CLIs for a review from visible Herdr panes in a per-project reviews workspace, separate from the dev-server and working workspaces. This skill drives **interactive agent CLIs through Herdr's agent surface**, not headless prompt mode. Herdr starts the real CLI UI in a pane, `herdr agent prompt` submits the instruction, and Herdr's lifecycle states tell you when each reviewer is finished. Read the `herdr` skill first if you are not already fluent in the CLI. This skill covers the review workflow; `herdr` covers the command surface, ID rules, and safety rules. ## Preflight Herdr is required. Verify you are inside a Herdr-managed pane before doing anything else: ```bash test "${HERDR_ENV:-}" = 1 ``` If the check fails, say you are not running inside Herdr and stop. Do not fall back to another multiplexer. ## Two Review Modes This skill runs in one of two modes. **Decide the mode before doing anything else**, because it changes the filenames, what the request file points the reviewer at, and what the reviewer is allowed to read/run. ### Mode A — Spec review (BEFORE implementation) Review the **design itself**, verified against the **existing codebase**. The reviewer judges whether the plan is correct, complete, and safe to build — and a core part of that is **reading the current code to confirm the spec's claims are true**: that the files, line references, integration points, current behaviors, and ass
