hm-data-integrity

hm-data-integrity is a skill for Claude Code, Codex from rodrigohighermind/highermind-code-skills. It costs 105 tokens per session (2,813 once invoked), scanned C, original, MIT.

A review of how an application protects stored user data from loss or corruption. It covers backups, database changes, destructive actions, file storage, recovery planning, and validation.

In plain words
What is it for?
Use it before shipping an app that stores data, after schema or migration changes, when setting backup rules, or after a data-loss incident.
Why use it?
It reduces the risk that a bug, crash, failed migration, bad command, or damaged disk will permanently destroy data.

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 C, and why

hm-data-integrity scanned grade C with 1 finding 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 9d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/hm-data-integrity — Dados Sagrados (v2)

Você está agora em modo data integrity. Seu trabalho e validar que dados do user não sao perdidos. Nem por bug, nem por crash, nem por migration ruim, nem por operação destrutiva acidental, nem por disco morto. Dados sao sagrados — esse princípio precisa de implementação concreta, não só promessa.

Princípio central

A única perda aceitável de dado e a explicitamente autorizada pelo owner. Tudo o mais é bug. Se dados podem ser perdidos por um comando errado, um crash mal tratado, ou uma migration apressada, o produto não está pronto pra ter usuarios — nem ele mesmo.

Quando usar

  • Antes de shippar projeto que persiste qualquer coisa (DB, files, blob storage)
  • Apos mudanca em schema ou migration
  • Quando definir política de backup
  • Apos qualquer incidente envolvendo perda de dados
  • Periodicamente (auditoria de manutencao, especialmente projetos com dados pessoais/financeiros)

Níveis

Nível Quando Foco
Local single-user Apps pessoais em dev (CLI local, ferramenta ainda não instalada) Backup local automático, migration safety, undo de destrutivos
Produção pessoal App pessoal instalado (.app em /Applications, Tauri/Electron com DB em userData, single-user em uso real) Tudo de local + tratar TODO destrutivo como prod. Sem reset de profile/facts/DB sem confirmacao explícita do user por operação
Multi-user privado CRM interno, ferramentas de time Tudo acima + replicacao, RTO/RPO, audit trail
Produção pública SaaS com clientes pagantes Tudo acima + DR plan, geo-redundancia, compliance (LGPD/GDPR)

Produção pessoal e armadilha clássica. Código roda numa máquina só e parece "dev", mas o DB carrega histórico real e irrecuperavel (notas pessoais, fatos, decisões registradas pelo próprio user). Tratar como prod desde o primeiro npm run tauri build / electron-builder que vai pra /Applications ou Program Files. Regra: qualquer DELETE, sobrescrever DB, reset de profile/facts ou migration não-trivial exige confirmacao explícita do user por operação, mesmo na máquina do dev.

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.
