herdr from istin/flutter_agent_harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Drive the herdr terminal multiplexer from inside fa: report on sibling agent panes, wait until another agent is genuinely blocked, spawn panes and prompt other agents through the herdr CLI/socket API. Only act when actually running inside herdr (HERDR_ENV=1); say so and carry on alone otherwise.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# herdr You may be running inside a [herdr](https://herdr.dev) pane — a terminal multiplexer that owns agent PTYs and marks every pane `working / blocked / idle / done`. ## Guard — read this first If `$HERDR_ENV` is not `1`, you are NOT inside herdr: this skill is inert. Do not install, probe for, or mention herdr; carry on without it. Verify from the bash tool (`herdr` calls are ordinary exec-tier commands, so the user's approval settings apply): ```bash printf 'herdr=%s' "$HERDR_ENV" ``` ## What herdr gives you - `herdr list` — panes with agent ids and states (`working`, `blocked`, `idle`, `done`, `unknown`). `blocked` means a sibling agent is waiting on a human — herdr exists to surface exactly that; do not busy-poll it. - `herdr spawn <agent> [prompt]` — start a new agent pane. - `herdr prompt <pane> <text>` — send a prompt to a pane. - `herdr wait <pane> --state blocked` — block until a pane reaches a state (use a timeout; never wait forever). ## Working with siblings 1. `herdr list` first; address panes by their id, never by guessing. 2. To hand work over: `herdr prompt <pane> '…'` then `herdr wait <pane> --state blocked --timeout 300`. …

How to install
mdr add istin/flutter_agent_harness/herdr@sha256:f6e0ce26c82b78a4The line at the top of this page pins the label git:20260925.4b7f8dd, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
