Automated summary
Scans and reports technical debt in source code, including TODOs, dead code, overly long functions, and outdated dependencies.
Strengths
- Systematic detection of multiple types of technical debt
- Prioritized report that facilitates corrective actions
- Uses native tools (grep, bash) with no external dependencies
- Multi-language support (JS, Python, Go, Ruby)
Limitations
- Heuristic detection may produce false positives
- No automatic fixes, only reports
- Can be slow on very large codebases
When you want to assess codebase quality, prepare for refactoring, or track technical debt over time.
If you need automatic problem correction, or if you require a deeper analysis with specific metrics.
Security analysis
SafeThe skill uses only read-only shell commands (grep) to scan source files for patterns; no destructive commands, no exfiltration, no disabling of safety features. The allowed Bash tool is used for benign code analysis.

技術的負債レポーター
コードベースの技術的負債を検出し、優先度付きのレポートを生成します。
検出項目
1. TODOコメント

grep -rn "TODO\|FIXME\|HACK\|XXX\|TEMP" --include="*.ts" --include="*.js" --include="*.py" --include="*.go" --include="*.rb"
2. 重複コード
- 類似パターンの検出（5行以上の重複）
- コピペの痕跡
3. 未使用コード
- 未使用の import/require
- 未使用の変数・関数・クラス
- デッドコード（到達不能なコード）
4. 長すぎる関数

5. 深いネスト
- 4階層以上のネストを検出
- 複雑な条件分岐
6. マジックナンバー
- 意味不明な数値リテラル
- ハードコードされた文字列
7. 古い依存関係
- package.json / go.mod / requirements.txt の outdated チェック
- セキュリティ脆弱性のある依存
実行フロー

- 各検出項目を並列で実行
- 結果を集計・優先度付け
- レポートを生成

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/technical-debt-detector-mm78nng6/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/technical-debt-detector-mm78nng6' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/technical-debt-detector-mm78nng6/download' --output '.skill-downloads/technical-debt-detector-mm78nng6/SKILL.md.part' && mv '.skill-downloads/technical-debt-detector-mm78nng6/SKILL.md.part' '.skill-downloads/technical-debt-detector-mm78nng6/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Read, Grep, Glob, Bash
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.
Claude Code
test -f '.skill-downloads/technical-debt-detector-mm78nng6/SKILL.md' && test -s '.skill-downloads/technical-debt-detector-mm78nng6/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/techdebt' && cp -R '.skill-downloads/technical-debt-detector-mm78nng6' '.claude/skills/techdebt'OpenSkills
OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/technical-debt-detector-mm78nng6'openskills read 'technical-debt-detector-mm78nng6'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/technical-debt-detector-mm78nng6/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
