At a glance

Generates a structured Bug Fix Brief (BFB) to document issue corrections.

  • Works in 4 steps: Gather Information → Generate Template → Ask Confirmation → …
  • User asks to create a BFB
  • SKILL.md covers Overview, When to Use, Instructions and Examples, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Bug Fix Brief is an agent skill from giuseppe-trisciuoglio/developer-kit. Generates a structured Bug Fix Brief (BFB) to document issue corrections. Includes root cause analysis, repro steps, fix options, and fix checklist. Use when user asks to create a BFB, document a bug fix, or generate a bug correction document.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Debugging and Root cause analysis. The repository describes itself as: Modular plugin marketplace for Claude Code and agentic CLIs, with validated, spec-driven skills, agents, commands, and workflows for Java, TypeScript, Python, PHP, AWS, and AI. The licence is MIT.

When your agent uses it

  • User asks to create a BFB
  • Document a bug fix
  • Generate a bug correction document

Example prompts

  • “Use the bug-fix-brief skill to generate a structured Bug Fix Brief (BFB) to document issue corrections”
  • “/bug-fix-brief”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, AskUserQuestion, Glob

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather Information
  2. Generate Template
  3. Ask Confirmation
  4. Write to Disk

What it can do on your machine

Read from SKILL.md and the folder at commit fe73fb3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • AskUserQuestion
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bug Fix Brief loads about 871 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 243 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~871

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Bug Fix Brief (BFB)

Overview

This skill generates a Bug Fix Brief (BFB): a structured document in docs/bfb/ that uniformly captures every bug fix with root cause, repro steps, fix options, and checklist.

When to Use

  • User asks to create a BFB
  • User wants to document a bug fix in a structured way
  • After identifying the root cause of a bug and before implementing the fix

Trigger: "create BFB", "document bug", "bug fix brief", "document fix"

Instructions

Phase 1: Gather Information

Check existing numbering:

bash
ls docs/bfb/ 2>/dev/null || echo "Directory does not exist"

Ask the user for:

  • BFB number (or propose next sequential)
  • Concise title (3-5 words, kebab-case)
  • Issue link (e.g. #1287)
  • Environment (Prod/Stg/Dev) + version
  • Observed vs expected behavior
  • File/function/line of the cause
Phase 2: Generate Template

Complete the full BFB template:

markdown
## BFB-XXX: [Title]

**Reference:** [Issue link]
**Environment:** [Env] `vX.Y.Z`
**Date:** YYYY-MM-DD

---

### 1. Bug
- **Observed:** [wrong behavior]
- **Expected:** [correct behavior]

### 2. Repro
  1. ...
  2. ... → [error/output]

### 3. Cause
`path/file.ext` — `function()` @ line N
[Why it happens, max 3 lines]

### 4. Decision
| Option | Fix | Choice |
|--------|-----|--------|
| A | [desc] | ✅/❌ |
| B | [desc] | ✅/❌ |

**Rationale:** [why]

### 5. Fix
- [ ] [change 1]
- [ ] [test]
- [ ] [verify repro]

### 6. Notes
[recurring patterns, links, warnings]
Phase 3: Ask Confirmation

Show the generated BFB and ask with AskUserQuestion:

  • "Create the BFB"
  • "Edit before creating"
  • "Cancel"
Phase 4: Write to Disk

Only after approval:

bash
mkdir -p docs/bfb

Write to docs/bfb/BFB-XXX-title.md

Examples

Input: "create BFB for login email null crash"

Final output:

markdown
## BFB-042: Login crash with null email

**Reference:** #1287
**Environment:** Prod `v2.4.1`
**Date:** 2026-05-02

---

### 1. Bug
- **Observed:** App crashes if email field is empty
- **Expected:** Error message "Email required"

### 2. Repro
  1. Open login screen
  2. Tap "Login" without entering email → NullPointerException @ AuthManager.kt:34

### 3. Cause
`AuthManager.kt` — `validateEmail()` @ line 34
Missing null check on email.trim()

### 4. Decision
| Option | Fix | Choice |
|--------|-----|--------|
| A | Add safe call `?.` | ✅ |
| B | Refactor with Result type | ❌ |

**Rationale:** Option A is minimal, zero impact.

### 5. Fix
- [ ] Add `email?.trim()?.isNotEmpty() == true`
- [ ] Test `validateEmail_null_returnsFalse()`
- [ ] Verify repro

### 6. Notes
- Check other forms for missing null checks

Best Practices

  1. Sequential numbering: BFB-001, BFB-002, no gaps
  2. Concise title: 3-5 words, kebab-case in filename
  3. Root cause: exact file, function, line
  4. 2+ fix options: with pros/cons and rationale
  5. Verifiable checklist: each item must be testable

Constraints and Warnings

  • Confirmation required: Always ask before writing
  • Max 3 lines for cause: Stay concise
  • Directory docs/bfb/: Create if it does not exist
