vinext: Command for Claude Code

.opencode/commands/fix-issue.md

fix-issue is a command for Claude Code, OpenCode from cloudflare/vinext. It costs 19 tokens per session (484 once invoked), scanned A, original, MIT.

A command workflow for fixing a GitHub issue from investigation through a pull request, a proposed code change for review.

In plain words
What is it for?
Use it when you need to read an issue, reproduce and fix the problem, update tests, run project checks, and prepare a pull request.
Why use it?
It keeps the work isolated in a separate Git worktree and branch, protecting the main checkout while the issue is being fixed. It also defines build, test, type-check, and lint checks for verification.

Command for Claude CodeOpenCode ✓ vendor

Written for Claude Code and OpenCode: $ARGUMENTS substitution, but also installed under .opencode/. Also seen: mentions AGENTS.md.

This is cloudflare/vinext's own configuration. It tells Claude Code and OpenCode how to work on vinext itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vinext configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is git worktree add ../vinext-fix-$ARGUMENTS -b fix/$ARGUMENTS-<slug> origin/main.

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

fix-issue 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 2mo 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.

What it actually says

Fix GitHub issue #$ARGUMENTS on cloudflare/vinext.

Step 1: Understand the issue

Run gh issue view $ARGUMENTS to read the issue. Understand what's expected, what's broken, and any reproduction steps.

Step 2: Create worktree and branch

Generate a short slug from the issue title (lowercase, hyphens, max 30 chars, no special chars).

git fetch origin main
git worktree add ../vinext-fix-$ARGUMENTS -b fix/$ARGUMENTS-<slug> origin/main

All subsequent commands must target the worktree directory. Use the bash tool's workdir parameter or explicit paths. Do NOT modify the main worktree.

Install dependencies in the worktree:

pnpm install

Step 3: Fix the issue

Work in ../vinext-fix-$ARGUMENTS/:

  1. Research the codebase to understand the problem area
  2. Implement the fix following the patterns described in AGENTS.md
  3. If touching server code, check dev/prod parity across:
    • entries/app-rsc-entry.ts
    • server/dev-server.ts
    • server/prod-server.ts
    • cloudflare/worker-entry.ts
  4. Add or update tests as appropriate

Step 4: Verify

Run all checks from the worktree:

pnpm run build
pnpm test
pnpm run typecheck
pnpm run lint

Fix any failures before proceeding.

Step 5: Commit and create PR

  1. Stage and commit with a clear message: fix: <description> (#$ARGUMENTS)
  2. Push: git push -u origin fix/$ARGUMENTS-<slug>
  3. Create PR:
gh pr create \
  --title "fix: <description>" \
  --body "Fixes #$ARGUMENTS

## Summary
<1-3 bullet points explaining what changed and why>

## Test plan
<what tests were added/updated>"
  1. Print the PR URL and number at the end. The review step needs the PR number.

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.
