What is claude-code-workshop-gdl-practica CLAUDE.md?

Repository instructions for a Spanish-language workshop that teaches Claude Code through small exercises and a toy payments app. The payments app contains deliberately planted bugs for later exercises.

Use it when working on the workshop exercises, the payments app, or the visual exercise guide. It explains where each section lives and which repository rules apply.

Without this context, an agent might repair intentional bugs, read protected files, or ignore the workshop's language and structure. The instructions mark those boundaries clearly.

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	$0.00223	$0.00223
Opus 5	$0.00112	$0.00112
Sonnet 5	$0.00045	$0.00045
Haiku 4.5	$0.00022	$0.00022

Measured 8d ago against content hash 94636f804730, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-07, from the pricing page.

Security

Grade A, and why

claude-code-workshop-gdl-practica CLAUDE.md 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 8d 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.

What it actually says

claude-code-workshop-gdl-practica

Repo de ejercicios del workshop. Root = mapa; el detalle vive en cada carpeta.

Estructura

03-conceptos/ a 11-insights/: un ejercicio por sección del deck, cada una con README
apps/pagos/: app de juguete con bugs sembrados (la usan 07, 08 y 09); ver apps/pagos/CLAUDE.md
guia/index.html: el mapa visual de los ejercicios

Reglas del repo

Los bugs de apps/pagos/ están sembrados A PROPÓSITO: no los "arregles" salvo que un ejercicio lo pida
Todo secreto aquí es falso; aún así, .env está fuera de alcance por hook
Los ejercicios se practican en español, términos técnicos en inglés

Por qué este archivo es corto

Es el ejemplo vivo de la sección 03: cada línea pasó el test "would removing this cause mistakes?". El resto son pointers.

Changes

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.
