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.

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 | $0.00076 | $0.00666 |
| Opus 5.5 | $0.00030 | $0.00266 |
| Sonnet 5.5 | $0.00015 | $0.00133 |
| Haiku 4.5 | $0.00008 | $0.00067 |
Grade A, and why
diagram 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.

Objetivo
Analizar el código fuente del proyecto (imports, llamadas a funciones, modelos de datos, flujos) y producir automáticamente diagramas en formato Mermaid o C4. Elimina el mantenimiento manual de documentación visual y la mantiene sincronizada con el código real.
Uso
/dc:diagram class
/dc:diagram sequence --file src/auth/login.ts
/dc:diagram architecture
/dc:diagram erd --dir src/models
/dc:diagram flowchart --feature checkout
/dc:diagram --output docs/arquitectura.md
Comportamiento
- Determinar tipo de diagrama solicitado
- Analizar archivos relevantes según el tipo:
class→ analizar definiciones de clase/interfaz e importssequence→ analizar llamadas a funciones y flujo de ejecuciónarchitecture→ analizar módulos de alto nivel, dependencias y boundaries (C4 Context/Container)erd→ analizar modelos, entidades y relacionesflowchart→ analizar lógica de negocio de un flujo o feature
- Construir el diagrama en sintaxis Mermaid
- Validar que la sintaxis sea correcta (no generar Mermaid inválido)
- Guardar como bloque en el archivo destino o imprimir en stdout

Reglas
- Máximo 20 nodos por diagrama para mantener legibilidad
- Si el scope es mayor, segmentar en subdiagramas por módulo
- Nunca inventar relaciones que no existen en el código
- Anotar la fecha de generación como comentario

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.
- 1mo ago First seen · 72 lines · 76 tokens per session scan A 4d424005e87f
diagram is a command published in the GitHub repository doncheli/don-cheli-sdd (57 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 76 tokens to every session and 666 once invoked, about $0.0003 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.
