hotfix

hotfix is a skill for Claude Code from bullish0x/GameStudio. It costs 35 tokens per session (1,556 once invoked), scanned A, a copy of hotfix, MIT.

A documented emergency-fix workflow for serious game bugs or security problems. It creates a separate hotfix branch, records approvals, and backports the fix to other branches.

In plain words
What is it for?
Use it to assess severity, record the incident, coordinate approval, apply the fix, and transfer it to the required branches.
Why use it?
It provides a traceable process for releasing urgent fixes while keeping the normal sprint workflow separate.

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

hotfix 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.

Origin

This is a copy

98% identical to hotfix — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explicit invocation only: This skill should only run when the user explicitly requests it with /hotfix. Do not auto-invoke based on context matching.

Phase 1: Assess Severity

Read the bug description or ID. Assess severity using these criteria:

  • S1 (Critical): Game unplayable, data loss, security vulnerability
  • S2 (Major): Significant feature broken, workaround exists
  • S3 or lower: Minor issue — normal bug fix workflow applies

Confirm with AskUserQuestion:

  • Prompt: "I've assessed this as [assessed severity] — [brief rationale]. Confirm severity to proceed:"
  • Options:
    • [A] S1 (Critical) — game unplayable, data loss, or security issue
    • [B] S2 (Major) — significant feature broken, workaround exists
    • [C] S3 or lower — redirect to normal bug fix workflow

If [C]: stop. Verdict: REDIRECTED — use the normal bug fix workflow for S3 and below.


Phase 2: Create Hotfix Record

Draft the hotfix record:

## Hotfix: [Short Description]
Date: [Date]
Severity: [S1/S2]
Reporter: [Who found it]
Status: IN PROGRESS

### Problem
[Clear description of what is broken and the player impact]

### Root Cause
[To be filled during investigation]

### Fix
[To be filled during implementation]

### Testing
[What was tested and how]

### Approvals
- [ ] Fix reviewed by lead-programmer
- [ ] Regression test passed (qa-tester)
- [ ] Release approved (producer)

### Rollback Plan
[How to revert if the fix causes new issues]

Ask: "May I write this to production/hotfixes/hotfix-[date]-[short-name].md?"

If yes, write the file, creating the directory if needed.


Phase 3: Create Hotfix Branch

Check whether this is a git repository:

Bash: git rev-parse --is-inside-work-tree 2>/dev/null

If this command fails or returns empty: note "Not a git repository — create the branch manually." and skip branch creation.

If the check passes, use AskUserQuestion before creating the branch:

  • Prompt: "Ready to create hotfix branch 'hotfix/[short-name]' from [base-ref]?"
  • Options:
    • [A] Yes — create branch
    • [B] Use a different base ref — I'll specify it
    • [C] Skip — I'll create the branch myself

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.
