What it does

Focused Fix is an agent skill from borghei/Claude-Skills. This skill should be used when the user asks to "fix a bug with minimal changes", "analyze change scope for a bugfix", "find the minimal set of files to change", "do a focused bugfix", or "scope a minimal repair".

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `evals/README.md`, `evals/grader.py` and `evals/runner.py`).

It sits in Development. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.

When your agent uses it

  • Asks to fix a bug with minimal changes
  • Analyze change scope for a bugfix
  • Find the minimal set of files to change
  • Do a focused bugfix

Example prompts

  • “fix a bug with minimal changes”
  • “analyze change scope for a bugfix”
  • “find the minimal set of files to change”
  • “/focused-fix”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Write a clear bug description — reproduction steps, expected vs actual behavior
  2. Run change_scope_analyzer.py to identify scope
  3. Review the recommended files and approach
  4. Make ONLY the changes needed to fix the bug
  5. Verify no unrelated changes leaked in
  6. Submit PR with focused change set

What it can do on your machine

Read from SKILL.md and the folder at commit 4a698e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Focused Fix loads about 1.5k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 736 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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); the scripts in this folder are not scanned.

Focused Fix

Category: Engineering Domain: Debugging & Maintenance

Overview

The Focused Fix skill enforces a disciplined minimal-change approach to bug fixing. Instead of refactoring or improving code during a bugfix, it identifies the smallest possible change set that resolves the issue. This reduces risk, simplifies code review, and prevents scope creep.

Use when

  • The user asks to "fix a bug with minimal changes", "do a focused bugfix", or "scope a minimal repair"
  • A bug report needs triage to identify the smallest set of files to touch
  • A PR is at risk of scope creep (unrelated refactors, style changes, "nearby" fixes)
  • A hotfix or release-blocker needs a low-risk, reviewable change set
  • The user asks "what is the minimal change to fix X?" or "which files do I need to touch for this bug?"

Clarify First

Before scoping the fix, confirm these inputs. If any is unknown or vague, ASK — do not assume:

  • Observable failure — the exact symptom, repro steps, and expected vs actual behavior (the bug description the analyzer matches against, and what the fix must resolve — not a guess at the cause)
  • Codebase path & file types — which directory and extensions to search (sets --path/--extensions)
  • Minimal vs structural — confirm this is a focused fix, not a refactor (determines whether out-of-scope "while I'm here" changes are rejected)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

bash
# Analyze a bug description to identify minimal change scope
python scripts/change_scope_analyzer.py --bug "Login fails when email has + character" --path ./src

# Analyze with JSON output
python scripts/change_scope_analyzer.py --bug "API returns 500 on empty array input" --path ./src --format json

# Analyze with specific file extensions
python scripts/change_scope_analyzer.py --bug "CSS overflow on mobile" --path ./src --extensions .css .scss .html

Tools Overview

ToolPurposeKey Flags
change_scope_analyzer.pyIdentify minimal files to change for a bugfix--bug, --path, --extensions, --format
change_scope_analyzer.py

Analyzes a bug description against a codebase to identify:

  • Files most likely related to the bug (keyword matching, import tracing)
  • Estimated change scope (number of files, lines)
  • Risk assessment for the change
  • Recommended fix approach (minimal vs. structural)

Workflows

Focused Bugfix Workflow
  1. Write a clear bug description — reproduction steps, expected vs actual behavior
    • Validate: the description names the observable failure, not a guess at the cause
  2. Run change_scope_analyzer.py to identify scope
    • Validate: analyzer output lists concrete files and an estimated line count
  3. Review the recommended files and approach
    • Validate: recommended approach is "minimal" — if it says "structural", stop and scope a refactor PR separately
  4. Make ONLY the changes needed to fix the bug
    • Validate: git diff --stat matches (or is smaller than) the analyzer's recommendation
  5. Verify no unrelated changes leaked in
    • Validate: git diff shows no formatting-only changes, no unrelated imports, no "while I'm here" edits
  6. Submit PR with focused change set
    • Validate: commit message states the exact bug fixed, and a regression test is included
Show full SKILL.md (299 more words)Show less
Scope Validation
  1. After making changes, re-run analyzer
  2. Compare actual changes against recommended scope
  3. Flag any out-of-scope modifications for separate PRs
    • Validate: any file touched that was not in the analyzer recommendation has a one-line justification or is reverted

Reference Documentation

Common Patterns

Do
  • Fix the exact bug reported
  • Add a regression test for the fix
  • Document why the fix works in the commit message
  • Keep the diff as small as possible
Don't
  • Refactor surrounding code during a bugfix
  • Fix "nearby" issues in the same PR
  • Change formatting or style in touched files
  • Add features disguised as bugfixes

Anti-patterns

Anti-patternFailure modeFix
"While I'm here" refactors in the bugfix PRBlast radius explodes; review time multiplies; unrelated regressions masked by the real fixOpen a separate PR for the refactor, tagged as refactor: not fix:
Reformatting or auto-save style changes in touched filesDiff becomes unreadable; real fix hidden in 200 lines of whitespaceRevert style changes before committing; configure the editor to format-on-save only for new files
Fixing the symptom in the wrong layerBug returns in a new form; accumulates workaround debtTrace to the root layer — analyzer's keyword-match output is a hint, not an answer
Skipping the regression test "because the fix is obvious"Bug silently returns on a refactor 6 months laterEvery fix: commit adds at least one failing-then-passing test
Treating change_scope_analyzer.py output as authoritativeAnalyzer is keyword/import-based, not semantic — misses dynamic dispatch, reflection, config-driven pathsUse it as a starting set; grep for callers and tests before committing to the scope
Bundling the fix with a dependency upgradeTwo risk profiles in one PR; if rollback is needed, both are lostLand the upgrade separately, then the fix against the upgraded baseline
