issue-development-loop

issue-development-loop is a skill for Claude Code, Codex from XnLemon/Neneko-skill. It costs 137 tokens per session (1,938 once invoked), scanned A, original, MIT.

A workflow for implementing GitHub issues from discovery through a reviewed pull request. A pull request is a proposed code change submitted for review before it is merged.

In plain words
What is it for?
Use it to inspect an issue, implement and test its changes, create a feature branch, open or update a pull request, and handle review feedback.
Why use it?
It organizes issue work into defined stages and validation, reducing the chance of publishing incomplete or unrelated changes.

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

issue-development-loop 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 4d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Issue Development Loop

Own the implementation loop from issue discovery through a clean reviewed pull request. Treat invocation of this skill as authorization to create a feature branch, commit the issue work, push that branch to origin, open or update its pull request, post review comments and replies, and resolve addressed review threads. Do not merge, close the issue manually, force-push, or modify unrelated work unless the user explicitly authorizes it.

Required Inputs And Dependencies

Require the user to identify the related issue by URL, repository plus number, or an unambiguous issue reference in the current repository. If multiple issues are declared, build one shared scope only when they are tightly coupled; otherwise process them as separate loops and PRs.

Require an origin remote and authenticated GitHub write access before the publication phase. Use the GitHub CLI or available GitHub connector according to repository conventions.

Load and follow both installed skills when their phases begin:

  • Use $neneko-cr only for the delegated review phase, subject to the strict review-only profile below.
  • Use $handle-review for the main agent's review-triage and fix phase.

If either dependency is unavailable, stop before that phase and report the missing dependency. Do not silently replace the independent review loop with a local self-review.

Establish The Contract

Before editing code:

  1. Read the complete issue, linked discussions, acceptance criteria, referenced documents, and relevant repository instructions.
  2. Inspect the current repository state, default branch, remotes, worktree changes, architecture, tests, and the current code paths implicated by the issue. Preserve unrelated user changes.
  3. Confirm that the reported problem or requested capability still applies to the current base. Separate the underlying need from any proposed solution in the issue.
  4. Create an issue ledger containing every required behavior, compatibility constraint, documentation change, test obligation, and explicit non-goal. Record ambiguous or contradictory requirements as blockers rather than guessing across a material product or API decision.
  5. Split substantial work into coherent development stages. Each stage must be independently testable and must advance the same PR toward the complete issue contract. Keep small issues as a single stage.

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.
