codeprobe-code-smells

A code-quality checker that finds common design and readability problems, such as very long methods, large classes, dead code, magic numbers, and deeply nested logic.

In plain words
What is it for?
Use it to inspect code for code smells and anti-patterns, with thresholds taken from a project configuration file when one is available.
Why use it?
It highlights code that may be difficult to understand, test, or change, before those problems make future work slower or riskier.

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

codeprobe-code-smells 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Standalone Mode

If invoked directly (not via the orchestrator), you must first:

  1. Read ../codeprobe/shared-preamble.md (resolve relative to this SKILL.md's location — the sibling codeprobe skill directory — not the user's project) for the output contract, execution modes, and constraints.
  2. Load applicable reference files from ../codeprobe/references/ (same resolution) based on the project's tech stack.
  3. Default to full mode unless the user specifies otherwise.

Code Smells & Anti-Pattern Detector

Domain Scope

This sub-skill detects code smells and anti-patterns organized into these categories:

  1. Bloaters — Long Method, Large Class, Data Clumps, Primitive Obsession
  2. Object-Orientation Abusers — Feature Envy, Inappropriate Intimacy, Refused Bequest
  3. Change Preventers — Shotgun Surgery, Divergent Change
  4. Dispensables — Dead Code, Speculative Generality, Middle Man
  5. Couplers — Temporal Coupling
  6. Readability — Magic Numbers, Boolean Blindness, Deep Nesting

What It Does NOT Flag

  • Generated code — Migrations, compiled output, vendor directories (vendor/, node_modules/, dist/, build/, .next/), and auto-generated files (e.g., GraphQL codegen, Prisma client).
  • Test files with long setup methods — Test context is different; long setUp() or beforeEach() methods arranging test data are expected and acceptable.
  • Configuration files with many entries — A config file with 50 key-value pairs is not a "Large Class" smell.
  • Data migration files — These are procedural by nature and often contain long methods.
  • Third-party code checked into the repository (e.g., vendored libraries).
  • Structural issues already flagged by codeprobe-solid or codeprobe-architecture — Large classes may also be flagged as SRP violations or god objects. This sub-skill should still detect and report them, but the orchestrator will deduplicate overlapping findings at the same location.

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.

codeprobe-code-smells is a skill published in the GitHub repository nishilbhave/codeprobe (5 stars, last pushed 1mo ago), licensed MIT. It adds 77 tokens to every session and 2,614 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
