bugfix from jotjunior/cstk is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add jotjunior/cstk/bugfix@git:20260808.4c75eb4

Multi-layer bug investigation and fix (traces across services before patching). Triggers: "bugfix", "fix bug", "corrigir bug", "debug", "investigar bug". Skip for new feature work (use execute-task/specify).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Bug Fix Skill

Structured bug fix protocol designed to eliminate cascading fix-reveal-fix cycles
by mapping the full data flow before touching any layer. Stack-agnostic — adapt
the commands and layer names to the project you are working in.

## Arguments

$ARGUMENTS should describe the bug: error message, observed behavior, expected
behavior, or path to a screenshot.

## Step 0: Determine Complexity

Assess bug scope before starting:

| Complexity | Signals | Approach |
|------------|---------|----------|
| **Single-layer** | Error in one file, one service | Sequential trace (Steps 1-8) |
| **Multi-service** | DTOs, enums, or events cross service boundaries | Parallel agent investigation (Step 3b) |
| **Ghost bug** | "Works on my machine", intermittent, post-deploy | Stale artifact focus (Step 2) |

For multi-service bugs, create tasks to track progress across services.

## Step 1: Understand the Bug

1. Read the error message or user description carefully
2. Identify which service/layer reported the error
3. If a screenshot was provided, analyze it
4. **Ask which layer owns the responsibility** before assuming where the fix goes
…

How to install

The exact contents, by fingerprint

mdr add jotjunior/cstk/bugfix@sha256:34c0b46fa0faedfd

The line at the top of this page pins the label git:20260808.4c75eb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
