What is kdd-security-scan?

A Spanish-language software skill for scanning a repository for security vulnerabilities and producing structured scan files that can be checked by automated rules.

Use it to audit a repository and produce a scan manifest, findings, and coverage data for a KDD security gate.

It turns a security review into versionable files with defined formats and coverage, instead of leaving the result as an informal report.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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	$0.00140	$0.02034
Opus 5	$0.00070	$0.01017
Sonnet 5	$0.00028	$0.00407
Haiku 4.5	$0.00014	$0.00203

Security

Grade A, and why

kdd-security-scan 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 11d 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.

Security Scan (Capa 3 de KDD)

Produce hallazgos de seguridad de un repositorio en el formato de contrato que audita la Capa 3 de KDD. Esta skill NO es el gate -- es la parte creativa/no determinista (la hace un LLM, con o sin subagentes) que el gate despues valida. Distincion central: el agente decide QUE es un hallazgo; el gate solo audita que el artefacto sellado cumpla forma y politica. Ningun LLM participa en el gate.

Adaptada del flujo de las skills de openai/codex-security (_bundled_plugin/skills/security-scan/, Apache-2.0), quitando toda dependencia del binario codex y de sus tools MCP especificas de la app de escritorio. Esta version corre con Bash + lectura de archivos nada mas -- cualquier agente sirve.

Cuando usarla

El usuario pide auditar un repo (propio o externo) por vulnerabilidades y quiere el resultado gobernado por KDD (versionable, gateado en CI, con politica declarativa), no un reporte suelto en prosa.

Insumos que necesitas antes de empezar

repo_root: raiz del repositorio a escanear (puede ser un clon separado del propio KDD -- ver la nota de portabilidad en scripts/vendor/codex-security/README.md, el finalizer no asume que el target viva dentro del repo KDD).
scan_dir: donde vas a escribir los 3 JSON. Por defecto security/scan dentro del repo KDD (coincide con el default de validate_security_findings.py); si estas gobernando un repo EXTERNO, cualquier directorio disponible sirve, con tal de que se lo pases explicito a finalize_scan_contract.py --scan-dir.
Los 3 schemas viven en knowledge/data_models/security/ (vendorizados del mismo origen, no los reinventes ni los edites).

Flujo

1. Alcance

Antes de tocar codigo, fija por escrito (2-3 lineas, no hace falta un documento aparte): que directorio/paquete se revisa, que queda explicitamente fuera, y contra que amenaza (codigo de terceros ejecutado localmente, superficie de red expuesta, manejo de secretos, etc.). Esto se vuelca en scan.scope.summary del manifest.

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.

kdd-security-scan is a skill published in the GitHub repository MauricioPerera/KDD (7 stars, last pushed 2d ago), licensed MIT. It adds 140 tokens to every session and 2,034 once invoked, about $0.0007 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.
