hotfix

hotfix is a skill for Claude Code from IdoCohen560/claude-unity-game-studio. It costs 35 tokens per session (1,221 once invoked), scanned A, a copy of hotfix, MIT.

An emergency software-fix workflow for serious problems such as an unplayable game, lost data, or a security flaw. It creates a separate Git branch and records the fix, approvals, testing, and rollback plan.

In plain words
What is it for?
Use it to assess critical or major bugs, prepare a hotfix, track regression testing, and apply the fix back to the relevant code lines.
Why use it?
It lets teams handle urgent fixes outside the normal sprint process while keeping a clear record of what changed and who approved it.

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

100% identical to hotfix — 0 lines 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 — 155 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. Determine severity:

  • S1 (Critical): Game unplayable, data loss, security vulnerability — hotfix immediately
  • S2 (Major): Significant feature broken, workaround exists — hotfix within 24 hours
  • If severity is S3 or lower, recommend using the normal bug fix workflow instead and stop.

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

If git is initialized, create the hotfix branch:

git checkout -b hotfix/[short-name] [release-tag-or-main]

Phase 4: Investigate and Implement

Focus on the minimal change that resolves the issue. Do NOT refactor, clean up, or add features alongside the hotfix.

Validate the fix by running targeted tests for the affected system. Check for regressions in adjacent systems.

Update the hotfix record with root cause, fix details, and test results.


Phase 5: Collect Approvals

Use the Task tool to request sign-off in parallel:

  • subagent_type: lead-programmer — Review the fix for correctness and side effects
  • subagent_type: qa-tester — Run targeted regression tests on the affected system
  • subagent_type: producer — Approve deployment timing and communication plan

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.
