herdr-issue-coordinator

herdr-issue-coordinator is a skill for Claude Code from owainlewis/agent-skills. It costs 68 tokens per session (3,109 once invoked), scanned A, original, MIT.

A coordinator for processing groups of GitHub issues through separate Claude Code sessions in visible Herdr tabs. Herdr is a tool that runs coding sessions in separate workspaces and tabs.

In plain words
What is it for?
Use it to coordinate several related GitHub issues, a parent issue, or a milestone, with one worker session and worktree per issue and tested pull requests.
Why use it?
It keeps each issue's code, branch, session, pull request, and progress separate while coordinating their order. It adds testing, review, and merge gates to the batch process.

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

herdr-issue-coordinator 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 10d 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 — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Herdr issue coordination

Use this session as the coordinator. Give each dispatched GitHub issue its own git worktree, branch, Herdr tab, and Claude Code session. Sequence the work. Keep implementation context in workers and all durable state in GitHub.

This skill is experimental. It depends on the herdr CLI and its API changes between versions. Verify the commands below against the installed binary before relying on them.

Explicitly naming /herdr-issue-coordinator, or explicitly telling the coordinator that agents may merge, authorizes in-scope workers to merge their own pull requests after every merge gate below passes. An implicit skill match does not grant merge authority: run in no-merge mode unless the user's words grant it. Neither mode authorizes deployment, release publication, destructive operations, branch-protection bypasses, or changes outside the supplied batch.

Preconditions

Stop if any of these fail. Do not substitute hidden subagents for workers.

  1. test "${HERDR_ENV:-}" = 1. You must be running inside a Herdr pane.
  2. herdr --version reports 0.8.0 or later. Earlier versions have no agent prompt and no agent start --pane, and this skill will not work.
  3. herdr agent lists prompt, and agent start accepts --kind and --pane. The binary is the authority, not this document.
  4. The working directory is a git repository with a GitHub remote and gh authenticated.
  5. Read the repository instructions, parent issue, sub-issues, declared dependencies, project board, issue state, and linked open or merged pull requests. A merged pull request is only evidence of completion when it closes or explicitly references the issue and its final change and proof satisfy the issue scope. Reconcile that state instead of dispatching again.
  6. Make every issue a complete task before dispatch. If a missing product or technical decision could change behavior, data, security, compatibility, operations, cost, or proof, mark that issue as needing human input.
  7. Build a dependency graph. Stop for human correction on a dependency cycle.

What this file has done since we first saw it

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.
