What is code-patterns?

A catalogue of recurring design and coding patterns found in a project’s own source code. It explains each detected pattern with a short real example and its file location.

Use it to browse all detected patterns, inspect one pattern, or see patterns added recently during a sprint.

It makes the team’s existing ways of solving problems easier to discover and reuse. This reduces the need to infer conventions from unrelated files.

code-patterns — Command for Claude Code by gonzalezpazmonica

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/gonzalezpazmonica/pm-workspace

Made for: Claude Code.

Or install pm-workspace, the plugin that ships this one along with the rest of its 124 commands, 75 agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00017	$0.00620
Opus 5.5	$0.00007	$0.00248
Sonnet 5.5	$0.00003	$0.00124
Haiku 4.5	$0.00002	$0.00062

Security

Grade A, and why

code-patterns 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 1mo 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.

Flujo

Paso 1 — Detectar patterns en el código

Analizar el código del proyecto buscando:

Categoría	Patterns a detectar
Arquitecturales	Repository, Service, Controller, CQRS, Mediator
Creacionales	Factory, Builder, Singleton, DI registration
Estructurales	Adapter, Decorator, Facade, Proxy
Comportamiento	Strategy, Observer, Command, Chain
Resiliencia	Retry, Circuit Breaker, Fallback, Timeout
Testing	AAA, Builder, Mother, Fixture

Paso 2 — Extraer ejemplos reales

Para cada pattern detectado:

Encontrar la mejor implementación en el código del equipo
Extraer snippet representativo (máximo 20 líneas)
Identificar fichero y autor

Paso 3 — Generar catálogo

🦉 Code Patterns — {proyecto}

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.

code-patterns is a command published in the GitHub repository gonzalezpazmonica/pm-workspace (50 stars, last pushed 3d ago), licensed MIT. It adds 17 tokens to every session and 620 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
