fr-runner

fr-runner is a skill for Claude Code from derio-net/super-fr. It costs 83 tokens per session (677 once invoked), scanned A, original, MIT.

A skill for operating and troubleshooting an autonomous runner, including the VibeKanban adapter. The runner picks up queued work phases and sends them to coding workspaces.

In plain words
What is it for?
Use it to check runner health, inspect phase readiness, diagnose dispatch failures, verify repository registration, and recover orphaned workspaces.
Why use it?
It helps explain why queued work was not dispatched, whether the runner is healthy, and how to recover workspaces left behind after a problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fr-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 27d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fr-runner

The runner is the autonomous consumer of queued phases. The framework surface is fr_dispatch (discover_plans + tick against the Runner protocol); the VibeKanban adapter is fr_vk (VkRunner, MCP client, card/workspace creation, the cron daemon python -m fr_vk.bridge). Neither is wired into the fr CLI — the daemon consumes them as a library on its pod.

Health checks

  1. Is the daemon ticking? The heartbeat gauge (willikins_heartbeat_last_success_timestamp) must be recent. Sync/failure counters: willikins_vk_bridge_sync_total, willikins_vk_bridge_failure_total{reason=…} — reasons: project_id_missing, unknown_repo, unit_mismatch, mcp_error, gh_error. unit_mismatch means the Issue is labelled for a runner that never takes that unit (e.g. phases labelled runner:herdr); fr apply --to now refuses that up front, so it points at labels set by hand or by an older fr.
  2. Is a phase eligible? fr status <plan-dir> on the plan: a phase dispatches only when its RENDERED labels say ready-but-not-synced, it has a tracking_issue, and the plan + spec are on origin/HEAD (the bridge pod pulls; reachability is why dispatch requires merged plans).
  3. Repo known to the runner? The VK adapter refuses repos its board doesn't list (unknown_repo failures) — add the repo in VK first.

Common faults

  • Queued forever, no failures: pod checkout stale (pull the repo on the pod), or every slot is in use (workspace budget — the runner defers and retries next tick, no action needed).
  • project_id_missing: the pod env lost VK_DERIO_OPS_PROJECT_ID.
  • Dispatched in error: fr undispatch <plan-dir> --yes closes the Issues and nulls the tracking fields; the runner's reaper archives the orphan workspaces on its next pass.
  • Card exists, workspace missing: set VK_BRIDGE_RECOVER_ORPHAN_CARDS=1 for one tick (opt-in recovery).

Boundaries

This skill OPERATES runners; queueing work to them is fr-dispatch's ceremony, and implementing phases is fr-execute's. The daemon never creates Issues (operator-only via fr apply --yes) and never implements work itself.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fr-runner is a skill published in the GitHub repository derio-net/super-fr (2 stars, last pushed yesterday), licensed MIT. It adds 83 tokens to every session and 677 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
