good-first-issue-batch

good-first-issue-batch is a skill for Claude Code, Codex from jayminwest/warren. It costs 80 tokens per session (2,249 once invoked), scanned A, original, MIT.

A workflow for turning a backlog of proposed GitHub issues into verified, contributor-ready issues. Each candidate is checked against the current code before it is published.

In plain words
What is it for?
Use it to recheck backlog entries, confirm defects at the latest revision, write accurate issue descriptions, and publish batches of beginner-friendly GitHub tasks.
Why use it?
It prevents filing issues that have already been fixed, are only partly valid, or no longer describe the current code.

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

good-first-issue-batch 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 5d 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.

Protocol: Good-First-Issue Batch

You turn seeds backlog rows into GitHub issues a stranger can actually pick up. The hard part is not writing them. It is proving they are still real.

The failure this skill exists to prevent

On 2026-08-07 six issues were bulk-filed straight from seeds rows. Within four hours a contributor commented on #808 that the work was already merged — it had been fixed in PR #774 four days before the issue was filed. Two more issues in the same batch (#806, #807) turned out to be half-dead. Nobody noticed because the seeds rows still said open, and the seeds rows still said open because the PRs that killed them were about something else entirely.

A tracker row is a lead, not evidence. Its age, its open status, and its description are all things a human wrote once and never revisited. The only evidence that a bug is real is the bug, in the code, at HEAD, today.

1. Operating principles

  • Re-derive every claim from HEAD. Never copy a defect description from the seeds row into the GitHub body. Open the file, confirm the defect, and write the body from what you just read.
  • Verify bullets independently. A three-bullet issue is three issues wearing a trenchcoat. One bullet dying does not kill the others, and one bullet surviving does not vindicate the rest. Grade each separately.
  • Line numbers are always stale. Every file:line in an old row has drifted. Re-resolve all of them; cite what you actually saw.
  • A dead issue costs more than no issue. A contributor who burns an evening on already-merged work may not come back. When verification is ambiguous, leave the row in seeds rather than publishing a maybe.
  • Never file for volume. Six solid issues beat twenty speculative ones. There is no quota.

2. Gather candidates

Pull open seeds rows that are plausibly contributor-sized and self-contained:

sd list --status open --format compact
sd search "<theme>" --format compact

Good raw candidates are bounded in blast radius, need no cluster access or live credentials to reproduce, and have an obvious done condition. Drop anything needing a running k8s deployment, a GitHub App token, or judgement about product direction.

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.
